Beyond oxidative damage: Reactive Oxygen Species (ROS) are essential for ordered plant development—ROS-producing enzymes coordinate cell proliferation, tissue integrity, and differentiation

Tokyo University of Science
Peer-Reviewed Publication

Reactive oxygen species (ROS) are often linked with oxidative damage. However, they are essential for cell signalling. A new study highlights their crucial role in plant development and morphogenesis. Using the liverwort Marchantia polymorpha, researchers found that disrupting the two genes responsible for producing ROS molecules led to disrupted plant growth and formation of disordered cellular masses. The study reveals a fundamental mechanism connecting cell division, tissue structure, and plant development.

The academic significance of this study has been highly recognized internationally, as evidenced by the simultaneous publication of a highlighted Dispatch article in the same journal by Professor Christine Foyer (University of Edinburgh, UK), a world-leading authority in plant reactive oxygen research.

Scientists uncover key protein that helps build and strengthen bone

Peer-Reviewed Publication

A recent study identified carbonic anhydrase III (CAR3) as a previously unrecognized protein critical for healthy bone development and regeneration. Using single-cell RNA sequencing, genetically modified mice, and bone repair models, researchers found that CAR3 helps osteoblasts mineralize collagen and strengthen bone tissue by interacting with collagen and bone sialoprotein. Mice lacking CAR3 developed low bone density and impaired bone formation, while CAR3-functionalized scaffolds significantly improved bone healing and regeneration following skeletal injury.

Sea anemone flips a human antiviral strategy on its head

The Hebrew University of Jerusalem
Peer-Reviewed Publication

A new study has uncovered a previously unknown antiviral defense mechanism in sea anemones, revealing that animals may have evolved more than one way to fight viral infections. Researchers discovered that a protein resembling a key component of the human immune system actually plays the opposite role, yet remains essential for effective antiviral protection. The findings challenge assumptions about the evolution of immunity and suggest that fundamentally different antiviral strategies have emerged across the animal kingdom.

A “copper economy” helps fungi and bacteria build better biofilms

University of Exeter
Peer-Reviewed Publication

Researchers led by Dr Seána Duggan, from the University of Exeter’s MRC Centre for Medical Mycology, have discovered that copper plays a central role in the partnership between fungus and bacterial microfilms The study, supported by the NIHR Exeter Biomedical Research Centre, reveals what the team describes as a microbial “copper economy”, in which the fungus and bacterium handle copper in different but complementary ways.

Does iron accumulation in the brain contribute to neurodegeneration?

Salk Institute
Peer-Reviewed Publication

Salk scientists explore long-standing mystery of why iron that builds up in neuronal cells becomes harmful over time in neurodegenerative diseases like Alzheimer’s and Parkinson’s, finding a new cellular process, named chronoferroptosis, wherein chronic iron dysregulation in neurons makes them more vulnerable to stressors. The study complements other ongoing research at Salk to design compounds that inhibit this pathway, and could be a promising future avenue for creating therapies that boost resilience in aging brains.

Teamwork: An unexpected strategy bacteria use to survive antibiotics

Baylor College of Medicine
Peer-Reviewed Publication

When bacteria are under antibiotic attack, it is not ‘every man for himself.’ Researchers have discovered that bacterial populations work as a team to survive antibiotics. The study reveals that bacteria pool their resources, helping quiescent or dormant cells survive. The findings help explain why some bacteria are hard to eliminate and suggest potential future approaches to improve antibiotic effectiveness.

Flowering plants diversified seed dispersal strategies earlier than thought, study suggests

American Association for the Advancement of Science (AAAS)
Peer-Reviewed Publication

While reproductive evolution of flowering plants (angiosperms) is traditionally linked to the end-Cretaceous biotic crisis, new research suggests angiosperm dispersal ecologies had already diversified by that time. The study is based on an analysis of flowering plant diaspores – the units comprising seeds and associated structures – from a Late Cretaceous fossil forest site in New Mexico. Flowering plants possess remarkable diversity in fruit and seed size and shape, reflecting morphology for dispersal by wind, water, and animals. This diversity is thought to have only originated during the Paleogene, despite an earlier increase in abundance and diversification of angiosperms across the Cretaceous. Here Jaemin Lee et al. suggest an earlier origin of variation in angiosperms seeds and fruits. They describe a relatively well-preserved collection of 77 diaspore morphotypes from a Late Cretaceous fossil forest in New Mexico, USA, featuring fleshy fruits and an average weight approximately the size of a blueberry. Though likely dispersed by vertebrates, their emergence may have been part of the shift to shady, humid tropical forests, rather than driven by vertebrate diversification. The results broaden “our understanding of forest ecology and plant-animal interactions during the first half of angiosperm evolutionary history,” say the authors.

Egg shuffle reveals how innate drivers and early environments affect European songbird’s ranges

American Association for the Advancement of Science (AAAS)
Peer-Reviewed Publication

Migratory birds fly precise seasonal paths to their breeding and non-breeding grounds, even when those grounds are separated by thousands of miles. But how do the birds know the difference between these two areas – is this information innate, or is it learned as hatchlings? The answers may affect how or if these birds can adapt to potential shifts in these grounds caused by global climate change. To learn more about what determines the non-breeding ranges of the pied flycatcher, Koosje Lamers and colleagues performed an egg shuffle, moving eggs from nests in the Netherlands to Sweden in a five-year experiment. The resulting “common garden” of fully genetic Dutch birds hatched in Dutch nests, genetically Dutch but Swedish-hatched birds, and fully genetic and hatched Swedish birds offered a way to track differences in migratory journeys. The researchers found that both inheritance and the hatching environment determined non-breeding areas, with the “half Dutch” birds traveling to non-breeding areas that were intermediate in location between the fully Swedish and Dutch populations.
