Shocking images of dead coral pieces fused and speckled with brightly colored plastics brought my attention to a new concern regarding coral reefs. Plastic pollution fused with coral rubble has been found along the shores of vulnerable coral reefs. Researchers took a closer look at colorful specks found within coral rubble and confirmed that the specks are common household plastics that have seeped into the pores of dead coral pieces.

Researchers from the Okinawa Institute of Science and Technology (OIST) and the University of the Ryukyus have called the fusion of polymers and dead coral ‘plasticorals’. This unfortunate discovery shows the impact of plastic pollution on the already threatened reef ecosystems. Pieces of dead coral themselves normally play an important role in an ocean’s ecosystem. New corals use these pieces as a stable material to build upon, and small marine life may use them for shelter.

The negative impact of plastic pollution on coral reef organisms has already been seen in previous studies. The occurrence of plasticoral fragments pushes for further research on its origin. Once the source has been determined, hopefully actions can be taken to reduce the impact and presence of plastic pollution in the ocean!

A beautiful image of the Joro spider brought me to this news release from the University of Georgia. The large black and yellow spider species that recently made its way to where I live in North Carolina has brought some concerns about how it may impact local insect populations. However, after researching the stomach contents of hundreds of Joro spiders across Georgia and South Carolina, they found that their diet is significantly different from local orb weavers. With a diet that consists largely of flies, there does not appear to be too much impact on struggling insect species.

While Joro spiders are not significantly affecting the food networks of local orb weavers or preying on other insects, they are taking up a lot of space. The spiders themselves are large, and the webs they make are often found to have tangled with other webs. The impact on physical space is difficult to determine due to a lack of data and researchers can’t say for certain if there is a competition for space.

The South has a similar climate to Japan, where the Joro spider originates from, which means they will likely be here to stay. The spiders are adaptable and can use their silk to carry themselves across long distances, and since they don’t pose a threat to other species, researchers suggest making peace with their presence. They are also pretty docile and make a meal of pests, so I am happy to accept the arrival of the Joro spiders!

What makes a good press release?

A news release that includes striking images initially catches my attention, but what prompts me to keep reading is a clear and direct headline. This gives me a pretty good idea of what to expect from the rest of the story, so I rely on approachable language that speaks to the purpose behind the release. I enjoy reading releases on conservation efforts because I have a soft spot for exotic species, especially those that aren't traditional favorites. It is also interesting to the narrative of a news release to be able to read quotes from the author that include a call to action and give more perspective to the inspiration for the research that is covered!

Professor Kyoko Miura from Kyushu University’s Faculty of Medical Sciences has found clues to living a long and healthy life through the biology of naked mole-rats. I was surprised to find that not only do naked mole-rats have particularly long lives, but they are also resistant to cancer. With advances in genome sequencing technologies, Professor Miura expanded genomic research from humans and mice to naked mole-rats to investigate what may cause the surprising resistance to age-related diseases in this species.

Her lab has a shocking 1,950 naked mole-rats, which makes it one of the world’s largest naked mole-rat colonies in the world. The population has gradually increased over the years, and the size of the population allows research on everything from genomes to cells and organs. Researchers were able to uncover a biological mechanism that allows the naked mole-rat to eliminate senescent cells on their own. These cells are believed to contribute to chronic inflammation and may progress various diseases in mammals, so this discovery could be a key factor in their longevity.

With lifespans increasing and more people living to old age, it is incredibly important to find ways to maintain our health as we age. The incredible discoveries by Professor Miura and her lab could allow people to live active and healthy lives with less threat of disease!

New research from the Integral Ecology Research Center provides evidence as to why the invasive barred owl has become a threat to the northern spotted owl. The researchers used GPS trackers on 56 barred owls in northwestern California, a first-time practice, to determine the types of forest features the invasive barred owls occupy. The results showed that barred owls chose the same types of old-growth habitats that spotted owls need to nest and roost, with 64% of a barred owl’s range overlapping with spotted owl habitats.

Barred owls put significant pressure on native California species which would affect more than just the spotted owl. Barred owls hunt several different species that spotted owls rarely go for, which implies there could be pressure on the broader old-growth community. While barred owls affect the greater food web, the forest stays the same. This allows researchers to manage pairs of barred owls out of the area, freeing a significant amount of space for spotted owls to reclaim. This research encourages important conservation efforts to manage invasive barred owl populations and protect native species like the spotted owl.

The incredible image of a tobacco hawkmoth feeding from a tobacco flower brought my attention to a news release by The Company of Biologists which discussed scent receptors in moth wings. Until now, there had been little known whether moth wings had a sense of smell. Bisch-Knaden and colleagues found that the wings have receptor proteins in their wings that can detect of different smells and tastes. This allows the moths to sniff out the plants they lay their eggs on.

After months of analysis, they identified the mRNA for 33 taste and scent receptors, 15 of which produced along the wing’s edge. The team fixed an electrical circuit to a wing and blew puffs of different odors. The wings only picked out two odors that naturally come from the leaves of the night shade plants they lay eggs on. There is still much to uncover about the many species of moths. Since they are primarily active at night, it requires an even more dedicated effort to observe their habits. It is amazing what new discoveries can be made when taking a closer look at moths and other insects!

While my daughter was hospitalized for her heart surgeries, she had many sensors and patches to help monitor vitals and heart activity. So, we are no stranger to uncomfortable sensors and patches that are a struggle to stay attached. Engineers at Penn State have found a fun and colorful approach that may make hospital stays and exams a bit easier.

The team has designed conductive ink that can be painted onto the skin in cute designs that can power robotic prosthetics, read brain waves, and other vital information! Traditional wearable technologies can be uncomfortable, restrict movement, and often fall off or become misplaced especially on little ones. This can result in inaccurate readings or the loss of signals entirely.

With this new technology, it creates not just a more approachable method to collect this information. The sensors are responsive, easier to apply to the skin, and is less likely to have the same interference as traditional electrodes. Having seen my daughter go through several ECG electrodes within a day, it’s amazing to see that these could effectively track readings during daily activities over 12 hours! It is exciting to see medical equipment develop in a way that is reliable and could be easier to track, but also approachable for kids receiving medical care!

Researchers from the School of Biology at the University of St Andrews with an international team analyzed a huge range of populations of over two thousand marine and terrestrial species. The team found a higher risk of extinction associated with decreasing local prevalence of species using a long-term database developed at the University of St Andrews to collect the data. They focused on groups of species from the same taxonomic group that are found in the same location and period of time which allowed scientists to observe change over time in a range of species. The analysis showed trends in prevalence matched extinction risks with decreasing prevalence typically associated with higher risk of extinction.

It is incredible to see how much data researchers were able to collect using BioTIME. It seems to be an incredible tool for tracking changes to different ecosystems over time and allowing scientists to monitor population changes. Extinction risks have risen with global climate changes which affect groups of co-existing species. The team found populations of at-risk species could be stable while non-threatened species could be decreasing. These temporal changes could give insight to better understanding of biodiversity changes and, hopefully, enable further conservation efforts in threatened species.

When a whale dies, the carcass sinks to the seafloor creating a whale fall which provides food to deep-sea life. From this release, I also learned that this results in a hotspot of biodiversity and an extensive fossil record. In collaboration between the Institute of Deep-sea Science and Engineering (IDSSE) of the Chinese Academy of Sciences, the University of Pisa, Italy, and Earth Sciences New Zealand in Wellington, researchers document the world’s deepest and largest deposit of whale fossils and active whale falls ever recorded. This site has been referred to as a “whale necropolis” due to the size and active ecosystem.

The research team completed over 30 dives using the HOV Fendouzhe submersible where they discovered five active whale falls and 476 whale fossils. Extrapolating from this data estimates this zone could contain over 10 million whale carcasses. The fossil record at this site spans at least 5.3 million years, and the newer skeletal remains support several communities of smaller marine organisms. This fascinating “whale necropolis” has already provided significant data on deep-sea ecosystems and evolutionary history of the organisms found here, and I look forward to what new discoveries the data reveals!

An international team of researchers from Hebrew University and the University of East Anglia have identified a gene that connects early life advantages with later life health risk. The team looked at a species of African turquoise killifish and focused on a gene previously linked to puberty to uncover more on this theory called “antagonistic pleiotropy.” Modifying this gene allowed fish to grow and reach sexual maturity faster, but this came with shorter lifespans and increased risk of cancer.

Researchers were able to see the process of evolution making trade-offs for the sake of reproduction. It is incredible to uncover natural biological priorities of continuity rather than longevity and how this is shown in our genes. This gene is also connected to cellular activity. With the increased activity during rapid growth in younger fish eventually is mirrored by the cellular damage that gradually leads to later life disease and decline.

This research can give valuable insight into cancer prevention and age-related diseases. With this understanding of natural trade-offs, the next step for this research will explore the possibility to separate the early-life benefits of this gene from the late-life consequences.

A news release by the University of Tokyo caught my eye with images featuring the beautiful blue colors of the sea creature appropriately referred to as the blue button. New research from the University of Tokyo’s Misaki Marine Biological Station has found that the species may live much longer than previously thought.

While upon initial inspection, the blue button looks like a jellyfish, it is actually a colony of small marine invertebrates. The colony is attached to a circular disc of chitin which acts as a flotation device. The individuals perform different tasks such as catching prey or reproducing to sustain the colony. Blue buttons are only 4-5 centimeters in diameter and drift with the current, making them difficult to find. They are able to survive conditions at sea, but struggle in captivity, which also proves a challenge for uncovering more about the organism.

After testing different conditions, researchers from the University of Tokyo and specialists at two Japanese aquariums found success in keeping 10 blue button colonies alive for up to 21 days. This allowed data to be collected on the colony and confirm that they could live several years. They were also able to take photographs of the blue buttons and observe their lifecycle. This incredible research allowed a closer look at the typically elusive blue button and how the colony works together to act as a single organism!

I recently discovered that a part of getting older is the unexpected and newfound interest in bird watching. So of course, my husband and I have downloaded an app developed by Cornell to identify birds based on their calls. Now, scientists from Cornell Lab of Ornithology have found that they can find more than just identifying information, but also how birds communicate the presence of predators to each other.

Networks of inexpensive microphones were placed so scientists could record and analyze hours of recorded bird sounds. The team of researchers used a tool that identified birds in the recording to better understand how birds respond to calls from a common predator, the American goshawk. The results showed that chickadees switched from territorial songs to alarm calls in response to a goshawk call only in areas with less vegetation beneath the trees. While territories with less vegetation are better for nesting, they are more open to predators. The pattern showed evidence that chickadees were making tradeoffs between defending a territory and evading predators.

Developments and accessibility in sound recording technology allow researchers to gather a wide range of valuable information. This data has the potential to further expand understandings of bird behavior without the costs and manpower of sending researchers out into the field!

While I have always relied on, and enjoyed the ambience of, lamps and streetlights during evening riverwalks, I never considered how much these may affect the ecosystem. Research from RPTU University Kaiserslautern-Landau shows that artificial light has a significant influence on natural life between bodies of water and surrounding habitats. Light pollution is increasing worldwide and can negatively impact the existing ecosystem even more than invasive species.

Researchers looked at how the feeding behaviors of spiders are affected by nighttime lighting and an invasive crayfish species. The results showed nighttime lighting caused spiders and crayfish to consume more, which included the larvae that would have hatched to be more food for land spiders. I was unaware how widespread the effects of light pollution can be in disrupting the natural transport of nutrients between water and land. However, this study provides insight that can enable conservation efforts and urban planning to find a more sustainable and eco-friendly approach to riverbank lighting!

Carcinization is a phenomenon in which species independently evolve to take on crab-like qualities. I have always wondered what about the shape of crabs was such an advantageous form to take. While several species adopt similar traits, the sideways crab walk is not as persistent. Researchers from eLife have examined the crab walk and how sideways locomotion may have developed over time.

Behavioral analyses of 50 species of true crabs revealed that sideways movement was only present in 35 species, while forward movement presented in 15 species. This change from forward to sideways walking occurred only once from a single common ancestor and was found primarily in true crabs. This deviation from carcinization habits in decapod species shows that while the body shapes may have evolved many times, behavioral changes like the sideways walk are more rare. The sideways crab walk has contributed to the ecological success of true crabs, but this advantageous trait has not been adapted as readily as the crab-like shape. This trait may affect other behaviors, or it may also be the result of a unique need for true crabs and few others. Luckily, the ecological success of true crabs means there are plenty of species to study. Though, I do look forward to seeing what other crab-like traits persist or deviate in other decapods!

As beautiful as butterflies are, my favorite fluttering pollinators have always been moths. I was immediately drawn to this release by the School of Science at the University of Tokyo which features fascinating close-up images of hawkmoths visiting the Japanese flower, Jasminanthes mucronate.

I was surprised to find out that this flower produces black nectar. This is the first time the colored-nectar flower is confirmed to be mainly pollinated by these nocturnal insects as opposed to daytime pollinators. Plants that produce colored nectar have been a recent point of interest as most nectar tends to be transparent. Color being the initial point of interest for these flowers, most research has been done in the day.

First author, Chiyoda shares a similar fondness for moths and investigates their underrepresented ecology. When he learned of the J. mucronate flowers, he hypothesized that it may be a perfect attraction to moths. After many attempts to catch hawkmoths and 75 hours of observation, Chiyoda and his colleagues confirmed a hawkmoth carrying the pollen.

There are still many interesting discoveries to be made with the flowers of J. mucronate flowers and their nighttime pollinators!

Much to the detriment of the gardens and house plants I have tried to keep, I do not have a green thumb. Which is what brought my attention to a news release by ETH Zurich which considers the question of why plants may not do well in dry soil. The basic needs of a plant are simple: water, light, and air. But the way they take up water from the soil requires a phenomenon called “negative water potential.” This occurs when negative tension allows plants defy gravity and move water from the soil up to their leaves. However, the plant’s ability to uptake water is limited by the way water moves through the soil.

As the soil dries, it is more difficult for the plant to draw water from the soil. Plants are able to conserve water through a few different methods. Stomata, sensitive valves on the underside of leaves, opens to allow carbon dioxide to flow in and closes to conserve water, depending on the environment. To draw up the water from pores in the soil requires a lot of energy for plants and there have been efforts to selectively breed plants that will absorb water more efficiently.

Researchers meet in the middle with an interdisciplinary approach. Soil physicists look at the foundation of plant growth and can see how soil pores can predict plant growth. Plant physiologists, however, focus on the plant from cells to roots to calculate water potential and understand how plants function. Admittedly, I may have oversimplified how complicated a plant’s needs in order to thrive! Which explains the browning leaves on my monstera and may indicate that it is time for a soil change.

Researchers have used samples collected from the Ryugu asteroid to learn more about the history of our solar system. To do so, scientists from Tokyo University of Science looked at a process called natural remanent magnetization (NRM) in which the magnetization of solar nebula materials can become locked in for billions of years when they are formed or altered. The measurements can provide valuable information on how the solar system evolved over time and how it was formed.

In 2020, Japan’s Hayabusa2 spacecraft collected samples from Ryugu, an asteroid that is thought to be related to events early in the solar system’s history. Materials from this asteroid offer an opportunity to further investigate the materials where there was previously limited information due to limited available samples.

The research team from the University of Tokyo was able to determine that the magnetization occurred before the particles solidified and was likely not a result of handling the materials after they were collected. The findings also suggest that the NRM characteristics were likely related to water-driven alterations on the Ryugu asteroid’s parent body. In these small details from an asteroid, scientists are able to better our understanding of the history of our solar system.

A new study from the Swedish Museum of Natural History tells how a collection of fossils recovered over 60 years ago have shed new light on a desert in northwestern Australia that was once a bay on the border of a prehistoric ocean.

Mass extinction and increasing temperatures marked the beginning of modern marine ecosystems which resulted in some of the earliest appearances of sea-going tetrapods, which quickly became aquatic apex-predators. The study, which looked at fossil remains from 250 million years ago, reveals a diverse ecosystem with worldwide trans-oceanic links.

Fossils of the marine amphibian, Erythrobatrachus noonkanbahensis, were initially discovered and recorded in the early 1960’s and 70’s. The original fossils were lost for around 50 years before being rediscovered in a search through international museum collections and leading to a reassessment of the species in 2024. The Erythrobatrachus fossils has been found to be the oldest currently known group of Mesozoic marine tetrapods and also show they came from two distinct species. Fossils of one of these species have even been found in deposits in the Scandinavian Arctic, which reveals these species were more diverse and spread out than previously known.

Scientists from the National Air and Space Museum’s Center for Earth and Planetary Studies map small mare ridges (SMRs) and how the formation may be connected to new potential sources of moonquakes that might affect future landings. I never considered how the moon’s tectonic activity may differ from Earth’s, or that a common tectonic formation, lobate scarps, comes from the moon slowly shrinking!

This tectonic activity has only recently been seen throughout the lunar mare. To understand future moonquakes, scientists compiled a catalogue of the known SMRs. They found SMRs originate from the same type of tectonic activity that forms lobate scarps and these often transition to SMRs. The discovery of these new SMRs and their similarity to lobate scarps may mean that moonquakes could occur in the lunar maria. This research not only gives us a better idea of the tectonic activity on the moon but also helps prepare for future missions!

Having seen the effects of Alzheimer’s disease on family members, I understand how crucial it is to intervene early. In recent years, it has been incredible to see research that has come out to enable lifestyle changes to reduce the likelihood of a dementia diagnosis. New findings from researchers at Johns Hopkins Medicine show that adults at the age of 65 or older who completed five to six weeks of cognitive speed training, with follow-up sessions one to three years later, were less likely to receive dementia or Alzheimer’s diagnosis even up to two decades later.

This is the first study that assesses 20-year links with dementia and Alzheimer’s disease with adults who participated in an earlier study between 1998 and 1999. The study looked at the long-term benefits of cognitive training. In the recent follow-up study, researchers found 25% fewer incidence of dementia diagnosis compared to the control group.

The findings of this two-part study are incredible as they suggest that relatively modest intervention and lifestyle change can have long-term effects and could offer some delay to dementia diagnoses. While more research is needed to understand and confirm the overall benefits of combined lifestyle changes and early intervention, this study suggests exciting potential to reduce risks in later-life health.

New diseases were among the many things introduced to the Americas from European settlers. Though new research from the University of Lausanne shows evidence that there were more pathogens in the region long before European contact than many, myself included, previously thought. Scientists have recovered a genome of a bacterium from human remains dating back roughly 5,500 years whose subspecies is associated with four modern treponemal diseases. This discovery has pushed back the genetic record of this species of pathogen by more than 3,000 years.

There are still many mysteries around when or how the different forms of the disease came about. The DNA recovered from the bacterium does not match any known forms that cause disease today, which shows that this form diverged very early on from the others, a split estimated to have happened around 13,7000 years ago. This research provides valuable insight into the diversity of pathogens that existed in the Americas much earlier than we previously thought, and my serve to help scientists prepare for future developments of disease emergence.

There has been recent speculation on the validity of “blue zones,” or regions where there are notably higher cases of longevity. However, a recent study co-authored by Dr. Steven Austad from the American Federation for Aging Research confirms the scientific validity of these zones.

This study references recent public discourse which questions the truth behind the record-keeping and suggests the potential for instances of fraud. However, authors of the study argue that these concerns were already considered in the development of the methods used to identify potential blue zones. Four regions showed an unusually high probability of individuals aged 90 and up with the information confirmed through records and demographic systems.

Blue zones are defined by patterns of longevity in the population rather than individual cases or outliers. As patterns change, the study also emphasizes that blue zones can lose their status with modernization, migration, and lifestyle changes that may disrupt the patterns of longevity. New blue zones emerge around the world while others, such as Okinawa and parts of Nicoya, lose patterns of longevity.

Dr. Austad argues that the appearance and disappearance of blue zones strengthen their scientific value and allows researchers to do further research on the factors that can influence healthy aging. This news release was great in explaining recent public perceptions of blue zones and how the study used this as an opportunity to expand further on the methodology and reinforce its scientific validity.

A news release from the Natural History Museum of Los Angeles County ends a longtime dispute over the existence of the Nanotyrannus. A multi-institutional team of researchers looked at the throat bone in the specimen and compared it to other similar species and the T. Rex. They found that though the Nanotyrannus was smaller, it was fully grown and distinct from the larger T. Rex.

Researchers are able to get an idea of an animal’s maturity by measuring the organization of the tissue in cross-sections of their bones. The initial hypothesis was that the bone belonged to a juvenile T. rex, so the bone structure was expected to show the animal was still growing. But after closer examination of the neck bone, it indicated the animal was near maturity and no longer growing.

This study is important in understanding the growth of different species and their accurate identification. The discovery of the Nanotyrannus gives us better insight on the ecosystem and depiction of Late Cretaceous North America. Now we know that the T. rex was not the sole predator and likely competed with the Nanotyrannus!

A news release from Osaka Metropolitan University discusses a new culture medium that allows stem cells from dogs to change into heart muscle cells. There are certain diseases that are similar between dogs and humans, which means these cells could have potential use in medicine.

These cells are typically difficult to study due to their sensitivity to culture conditions and risk losing their ability to develop or develop into the wrong type. However, an international team of researchers led by Professor Shingo Hatoya of the Graduate School of Veterinary Science at Osaka Metropolitan University has developed a culture medium that allows stem cells to develop into heart muscle cells.

The cells can be developed into heart muscle cells and would allow researchers to study how they are affected by new compounds. This would result in incredible development in drug development!

It is typically understood that invading queens will fight and kill the existing queen herself to take over a colony. However, new research from Kyushu University in Fukuoka Japan details a new strategy in which an invading ant queen compels the colony to attack their own queen before taking her place. This was an interesting discovery because it was first made by first author of the paper, Taku Shimada, in his blog, ‘AntRoom.’ Assistant Professor Keizo Takasuka from Kyushu University found the post three years later and wanted to document the discovery.

The parasitic queen used two chemical sprays, suggested to be formic acid, against the host colony queen to incite a lethal attack from the host to their queen. After the host queen’s death, the parasitic queen is accepted by the colony and begins laying her own eggs. The formic acid is commonly used by ant species to warn comrades of predators, but in this case, deceives the colony to attack their queen. The host and parasite are not closely related, but belong to the same genus, which is known for two origins of social parasitism. This is an example of convergent evolution, where unrelated species develop similar traits.

This release includes fascinating imagery depicting the parasitic ant queen inciting the attack on the host queen. There is also a link to a video to see the ants in action! The background to the study is also an interesting case on how other types of media, in this case a blog post, can lead to new scientific discoveries!

A news release from the University of Copenhagen highlights three new toad species that skip the tadpole phase of life and instead give birth to live toadlets. The tree-dwelling toads from Africa have developed internal fertilization and are able to give birth away from water. This is a rare trait that only a few frog species from South America and southeast Asia have developed. Textbooks and common knowledge consider the lifecycle of frogs as a standard process from eggs to tadpoles to froglets to adults. But there is more variety to their reproduction than you may think!

The first toad species capable of live birth was discovered in 1905 and thought to be the only one. After conducting more research on the evolution and genetic diversity of these frogs, first author Christian Thrane from the University of Copenhagen, was able to bring awareness to these new species. This study not only provides more insight to different evolutionary directions of certain species but could also have important implications for conservation. Many of these species exist in small habitats that are threatened by deforestation, mining, and climate change. With threatened habitats and most of the Tree toads on the brink of extinction, the group of researchers are concerned about the impacts this will have on biodiversity and the future of these species.

A new species of the jellyfish known as the man-of-war has been discovered by a student-led research group from Tohoku University. A new species of Physalia which was named Physalia mikazuki after a Sendai samurai, Date Masamune, known for the crescent moon on his helmet. There are four other known species of Physalia, so the researchers recorded any and all features that were unique. There was previously assumed to be only one genus of the jellyfish in the area, but after the careful analysis, and matching DNA sequences, it was revealed that there had always been two species, the difference had just gone unnoticed until now.

This jellyfish had previously never been seen this far north. To understand why, researchers used simulations of ocean currents and found that warm currents have likely begun to extend farther north, bringing the jellyfish with them. The discovery of the new jellyfish species, with a particularly nasty sting, shows how important it is for researchers and the public to be aware of changes in the ocean’s ecosystem. These changes can result in new appearances of otherwise unexpected organisms.

Much like second author Yoshiki Ochiai, the striking blue jellyfish is what initially caught my eye. The text was well structured, summarizing the key findings in the first paragraph, following with a captivating perspective of the researcher’s process in making this discovery. The release concluded with quotes from the author that tied in public relevance, which communicates the importance of the study to journalists and the general public.

Researchers at Utrecht University look into why earthquakes still occur in regions that tectonically, should have low activity. There are regions in America, France, and the Netherlands where there is a shallow subsurface which allows the faults to become stronger when they start to move. In theory, this should make it impossible for earthquakes to occur. However, while faults in shallow the subsurface are expected to be stable, earthquakes still happen.

When this movement happens, it is usually the result of human activity. These shallow faults have previously been stable and have not moved for millions of years. During this time of inactivity, the faults can gradually “heal” and build up extra strength. So, when movement does happen, the faults can release that stored energy in a single seismic event.

This can be an issue as people living in areas where earthquakes rarely occur, they may lack infrastructure that would withstand earthquakes. Since they are also occurring near areas of human activity, this could be a greater hazard than natural earthquakes, which typically occur deeper underground. It was interesting that once these earthquakes do occur, they return to a stable state. This research will be incredibly important for ensuring safe geothermal energy extraction, underground storage, and earthquake risk assessment.

Promoting conservation efforts, especially in the case of important pollinators like bats, has always been an interest of mine! In this release from The Company of Biologists, research from the University of New England, Australia, suggests that efforts to support the bat population could be unintentionally dangerous. Bat boxes are set out to give bats a place to roost and encourage them to stay in certain areas. These boxes are often designed to stay warm to provide bats a comfortable place to rest. However, in warm weather, the boxes have been exceeding safe temperatures for their survival. If the bat box has been set in a spot exposed to full sun, rising temperatures could cause the box to exceed 122 degrees Fahrenheit or 50 degrees Celsius. The rise in temperatures could be fatal while the bats are sleeping and unable to relocate.

This was incredibly eye-opening to me, as I live in an area with high temperatures and hadn't considered how much planning should really go into setting up bat houses or similar conservation practices. I have been thinking about setting up bat houses on my property to encourage bats to hang around and help with pest control and pollination, so this news release helped me get a better idea of risks and best practices!

When I was pregnant, like many other expecting parents, I looked for every method and tip to promote my baby’s development. In a study from the University of Cambridge, researchers found that a good type of gut bacteria in pregnant parents could help! The study looked at the placentas of mice with the gut bacteria compared to those without it. More complications occurred in the pregnancies of mice without the bacteria present, which shows that the gut microbiome affects the placenta and can significantly impact pregnancy!

It is incredible to see the many factors that contribute to the health of the parent and the baby during pregnancy as more research comes out. This study could change the outcome of many pregnancies by testing the gut biome for potential complications and allow for early intervention. For instances of gestational diabetes, pre-eclampsia, miscarriage, and stillbirth could potentially be avoided by the use of probiotic supplements.

With all the risk and uncertainty in pregnancy, it would be amazing to see the types of intervention made possible by this research!

Scientists from the Graduate University for Advanced Studies, SOKENDAI, found that shortfin mako sharks were warming up before diving deep to hunt for food. Scientists attached data loggers to the sharks to track the temperatures of the water, their bodies, and the depths of their dives. Though the sharks are a species found in warm water, they swim to deeper waters where more prey are found. Scientists found that their body temperature decreased slowly while descending to cold waters, but increased much quicker when rising to warmer water at the surface. But rather than just swim to warm waters to recover from the cold, one shark prepared for its dive by warming up beyond the surrounding water to stay in warm in cold water for a longer period! This is a fascinating ability of regulating their body heat that is not seen in other fish species, and it was incredibly interesting to see a shark prepare for its journey to deep water!

Researchers from Huntsman Cancer Institute found that individuals with multiple tattoos may have less risk of skin cancer. Conversely, the team noticed that those with only one tattoo had an increased likelihood of having melanoma. At first, it was thought that those with tattoos would have an increase in skin cancer risk due to potential heavy metal exposure and irritation from tattoo sessions, but it was really interesting to see that the risk was lower for those with multiple tattoos! There is speculation that those with multiple tattoos take sun protection precautions to keep tattoos from fading, but more research is needed to understand the pattern. I have a few tattoos myself, so it is really fascinating to consider if I may be mitigating my risk in my own tattoo care!

Color changing mold on cheese rinds offers a fascinating, and delicious, opportunity to see evolution in action! Researchers from Tufts University collected samples of mold growing on Bayley Hazen Blue rinds from the Jasper Hill caves, where they are left to ripen. Upon returning to the cave for more samples, they noticed the mold had changed from green to white! The mold was green from a gene that produces melanin, but to save energy, stopped melanin production causing the mold to turn white. It is so interesting that researchers were able to see this process happening over just a few years. Now, researchers can study the mold and look into its genetic diversity at the same time as contributing to new attributes in the cheese!

Microplastics have become a major concern in recent years with its presence in drinking water, food, and even in our own bodies. Researchers from the University of Rhode Island College of Pharmacy have found these plastics can collect in the brain and cause Alzheimer’s disease-like symptoms. Assistant professor Jaime Ross and her team conducted an experiment exposing groups of mice with different genetic indicators of Alzheimer’s disease to microplastics. The results showed that male and female mice experienced different symptoms of cognitive decline, similar to what we see in humans. With how prevalent micro- and nanoplastics are, her research will hopefully inspires more research and regulation regarding plastic use!

Northwestern University scientists have created a new tool to help track infant development as early as 16 days old! As a new mom, making sure my daughter is meeting her goals and developmental milestones is my primary focus and this is an incredibly helpful toolkit to make available to families. The existing tool to track an infant's development began at three years old, which made early intervention difficult. This new NIH Baby Toolbox aims to be widely available and measure the development in children too young to answer questions. It can be difficult to keep track of each developmental leap as a parent, and even more so to get the necessary support should your child require extra help. It is amazing to see this kind of tool be made available for babies at such a young age so that early intervention is possible!

As someone who always manages to let their phone die, this release from the University of Ottawa stood out to me! Researchers from uOttawa in collaboration with Canadian Nuclear Laboratories, found a way to measure and compare batteries’ performance to develop long-lasting betavoltaic batteries. This advancement could allow pacemakers to run for a lifetime without depletion, batteries to function in extreme conditions, and provide a more sustainable source of energy!

A news release by Kyoto University details an unexpected comeback from the brink of extinction in red headed wood pigeons. Although the population of this pigeon fell drastically low, it made a quick comeback after its primary predator - the feral cat - was removed. This was unexpected due to the low genetic diversity of the species after inbreeding due to low population. However, researchers found that a harmful mutation common in other wood pigeons was lower in this small population of the red headed wood pigeons. With how difficult it is to bring a species back even with devoted conservation efforts, it is amazing that a feature of its population decline actually enabled its revival!

This release from the Frontiers tells an interesting story of how a reading robot became part of the family for many households. A robot designed to help preschoolers with reading was introduced to 20 families in 2021 and by 2025, almost all still had their robot. It had become a point of nostalgia, comfort, or even like a member of the family for many. In a time when technology is shaping so much of the world we live in, it was so interesting to see other ways assistance technology can be integrated into people’s lives; even as intimately as family!

A news release by the National Institutes of Natural Sciences describes the discovery of an object beyond Pluto that provides more insights into the outer Solar System. The object, currently labeled as 2023 KQ14, has a peculiar orbit that is different from other objects of its kind. The FOSSIL team’s simulations of 2023 KQ14’s orbit, some of which utilized National Astronomical Observatory of Japan’s PC cluster, suggest that the orbit has been maintained for at least 4.5 billion years. These observations imply ancient astronomical events that contribute to our understanding of the history of the Solar System. It is interesting how this could imply that a ninth planet may have existed but was potentially pushed out of the Solar System.

Microplastics are a recent point of concern in conversations about plastic waste and its impact on the environment. This news release by Kaunas University of Technology was informative in how it broke down the different challenges in combating plastic waste. With an increased use in plastic worldwide, pollution from plastic use has made its way into water supplies, different food sources, and even the most unexpected places such as breast milk. One of the main challenges faced with dealing with plastic waste is outdated waste management. I was surprised to learn that even with the increased plastic use, new regulations have only just been proposed. The EU has a goal of reducing plastic waste overall, but a significant challenge is dealing with the plastic waste that already exists. With increased and more efficient recycling efforts, the target is to recycle 55 percent of plastic waste by 2030.
