Mythbusting: 5 common misperceptions surrounding the environmental impacts of single-use plastics
Stand in the soda pop aisle at the supermarket, surrounded by rows of brightly colored plastic bottles and metal cans, and it's easy to conclude that the main environmental problem here is an overabundance of single-use containers: If we simply recycled more of them, we'd go a long way toward minimizing impacts.

Greenhouse effect of clouds instrumental in origin of tropical storms
With the tropical storm season in the Atlantic Ocean underway and already well into the Greek alphabet for naming, better storm track prediction has allowed timely evacuations and preparations. However, the formation and intensification of these storms remains challenging to predict, according to an international team of researchers who are studying the origin of tropical cyclones.

Hidden losses deep in the Amazon rainforest
New research shows that animal patterns are changing in the absence of landscape change, which signals a sobering warning that simply preserving forests will not maintain rainforest biodiversity.

Accessible healthcare could be key to solving climate crisis
Making high-quality care accessible to local and Indigenous communities was correlated with a 70 percent reduction of deforestation in an Indonesian national park. By offsetting healthcare costs, the community-designed program reduced incentives for illegal logging. Watch the video:

Super-resolution microscopy and machine learning shed new light on fossil pollen grains
Plant biology researchers at the University of Illinois and computer scientists at the University of California Irvine have developed a new method of fossil pollen identification through the combination of super-resolution microscopy and machine learning. The team developed and trained three convolutional neural network models to identify fossil pollen specimens from an unknown group of legumes.

Chemists develop framework to enable efficient synthesis of 'information-dense' molecules
A team led by scientists at Scripps Research has developed a theoretical approach that could ease the process of making highly complex, compact molecules. Such molecules are often found in plants and other organisms, and many are considered desirable starting points for developing potential new drugs. But they also tend to be highly challenging for chemists to construct and modify in the lab--a process called synthesis.

Coastal permafrost more susceptible to climate change than previously thought
Research led by Micaela Pedrazas, who earned her masters at The University of Texas at Austin Jackson School of Geosciences working with Professor Bayani Cardenas, has found permafrost to be mostly absent throughout the shallow seafloor along a coastal field site in northeastern Alaska. That means carbon can be released from coastline sources much more easily than previously thought.

Easy home cancer test means patients can avoid hospital for colonoscopies
Findings from the largest international research study found that using FIT is almost 100% accurate at ruling out bowel cancer in patients with suspicious symptoms. During COVID, cancer diagnostics services were suspended and continue to be disrupted. Clinicians in London, along with NHS England, London region, agreed to rapidly implement the use of the same easy home test used in the bowel cancer screening programme, the FIT (faecal immunochemical test), to rule out cancer in people with suspected symptoms.

Where will the seabirds go?

Seabird response to abrupt climate change 5,000 years ago transformed Falklands ecosystems
A 14,000-year paleoecological reconstruction of the sub-Antarctic islands led by University of Maine researchers has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Islands ecosystems through the deposit of high concentrations of guano that helped nourish tussac, produce peat and increase the incidence of fire.

Ancient Maya built sophisticated water filters
Ancient Maya in the once-bustling city of Tikal built sophisticated water filters using natural materials they imported from miles away, according to the University of Cincinnati. A multidisciplinary team of UC anthropologists, geographers and biologists identified quartz and zeolite, a crystalline compound consisting of silicon and aluminum, that created a natural molecular sieve. Both minerals are used in modern water filtration.

RIT scientist receives NSF funding to explore cellular compartmentalization in bacteria
A Rochester Institute of Technology scientist received funding from the National Science Foundation to better understand the fundamental rules that allow bacteria to compartmentalize the functions within their cells. The $559,000 NSF grant will allow Moumita Das, an associate professor in RIT's School of Physics and Astronomy, to explore the role phase separation plays in this process.

Type 1 diabetes: Tannic acid encapsulation protects transplanted islets from rejection
One therapy for Type 1 diabetes is promising -- transplanting pancreatic islets from cadavers -- but a need for immunosuppression and a reactivated autoimmunity lead to low graft viability and function after five years. Now researchers show that a protective coating of alternating layers of two biopolymers delays allograft and autoimmune-mediated rejection in mouse models of T1D.

Cicada-inspired waterproof surfaces closer to reality, researchers report
A multidisciplinary group that studies the physical and chemical properties of insect wings has demonstrated the ability to reproduce the nanostructures that help cicada wings repel water and prevent bacteria from establishing on the surface. The new technique - which uses commercial nail polish - is economical and straightforward, and the researchers said it will help fabricate future high-tech waterproof materials.

Finally, a way to see molecules 'wobble'
Researchers at the University of Rochester and the Fresnel Institute in France have found a way to visualize those molecules in even greater detail, showing their position and orientation in 3D, and even how they wobble and oscillate. This could shed invaluable insights into the biological processes involved, for example, when a cell and the proteins that regulate its functions react to a COVID-19 virus.

Researchers examine impact of digital information on COVID-19 decisions and behavior
Misra and Wernstedt have received a Rapid Response Research (RAPID) grant from the NSF to conduct a survey among 400 respondents in five metropolitan areas in the United States -- Washington, DC; New York; Chicago; Houston; and Atlanta -- that will track differences in risk perceptions, preferences, and self-reported behaviors within each area and compare them across locations. The study commenced in April, and data will be collected at multiple time points during the remainder of 2020 and through the middle of 2021.

Researchers eye a system that uses marine microplastics to get rid of marine microplastics
Tiny particles of plastic, called microplastics, pose a host of environmental problems in marine ecosystems and beyond. Recent research has found that these microplastics are found in more places, and in larger amounts, than anyone anticipated. Now researchers are working to develop a self-sustaining system that uses microplastics to capture more microplastics.

Simple actions can dramatically improve a person's chances of surviving a landslide, according to records from 38 landslides in the US and around the world. People who survived landslides tended to show key behaviors such as being aware of the risk, moving to higher ground, and making noise if buried.

How'd we get so picky about friendship late in life? Ask the chimps
When humans age, they tend to favor small circles of meaningful, already established friendships rather than seek new ones. People are also more likely to lean toward positive relationships rather than ones that bring tension or conflict. These behaviors were thought to be unique to humans but it turns out chimpanzees, one of our closest living relatives, have these traits, too. The study shows what's believed to be the first evidence of nonhuman animals actively selecting who they socialize with during aging.
