Phys.org / Smart materials and drug delivery could exploit lipid molecules that reorganize at drying interfaces
Minor changes in moisture level can promote lipid molecules to reorganize themselves in biomaterial or biomembranes. This can affect how the skin, lungs and tear film protect us from dehydration. This new discovery from Lund ...
Phys.org / Birds achieve sweet success: What adaptations to high-sugar diets reveal about metabolism
Anyone who has seen a hummingbird poking her beak deep into a trumpet creeper blossom, or a honeyeater using its brush-tipped tongue to extract nectar from eucalyptus flowers, has witnessed something that, from a human perspective, ...
Phys.org / Rice gene discovery could cut fertilizer use while protecting yields
Researchers from the University of Oxford, Nanjing Agricultural University, and Institute of Genetics and Developmental Biology (Chinese Academy of Sciences) have finally identified the master regulator in plants that balances ...
Phys.org / How RNA binding selectivity arises from disordered regions
RIKEN researchers have discovered how an enzyme modifies gene expression by targeting certain stretches of messenger RNA (mRNA) while leaving others alone. This finding could contribute to the rational design of drugs that ...
Phys.org / Ancient mosquitoes developed a taste for early hominins, research reveals
The preference of some mosquitoes in the Anopheles leucosphyrus (Leucosphyrus) group—including those that transmit malaria—for feeding on humans may have evolved in response to the arrival of early hominins in Southeast ...
Phys.org / How oxygen enriched Earth's atmosphere 2.5 billion years ago
Cyanobacteria, as they still exist today, were the first organisms to carry out photosynthesis and release oxygen. Produced in primeval oceans about 2.5 billion years ago, this oxygen accumulated in Earth's atmosphere on ...
Phys.org / Atomic precision unlocks smarter oxygen reduction catalysts
Tiny changes at the atomic scale can determine the future of clean energy. In a new study, Tohoku University researchers have revealed how the precise coordination environment surrounding a single cobalt atom dramatically ...
Phys.org / Nanochannel method makes ion membranes twice as strong for clean energy
Researchers have found a way to fabricate film-thin membranes imbued with super strength that could extend the durability of decarbonization technologies. Chemical engineers at The University of Queensland are harnessing ...
Phys.org / Will melting glaciers slow climate change? A prevailing theory is on shaky ground
For scientists who study the Southern Ocean, a long-standing silver lining in the gloomy forecast of climate change has been the theory of iron fertilization. As temperatures rise and glaciers in Antarctica melt, ice-trapped ...
Phys.org / Endangered giant clam feeding strategies could determine species' future survival
Giant clams (Tridacna gigas), members of the family Tridacnidae and among the most striking inhabitants of tropical coral reefs, are being driven toward extinction. Over-harvesting for jewelry, the aquarium trade, and food, ...
Phys.org / Wildfire smoke linked to rise in violent assaults, 11-year study finds
A new study spanning 11 years of data has revealed a clear link between wildfire smoke pollution and an increase in violent assaults in Seattle. These findings represent the first direct causal evidence that short-term exposure ...
Phys.org / A puddle that jumps: What bubble bursts reveal about water on lotus-like surfaces
Water droplets have a unique ability: They can leap from a surface on their own. This can happen for a variety of reasons, such as when a surface repels water or when heat is involved, such as a water or oil droplet skittering ...
