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 / Tackling the global tuberculosis crisis: An emerging class of antibiotics offers hope
Researchers from the University of Sydney and the Centenary Institute have discovered how a promising class of experimental antibiotics disrupts the bacterium that causes tuberculosis (TB), paving the way for urgently needed ...
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 / 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 / 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 / New technique spots hidden defects to boost reliability of ultrathin electronics
Future devices will continue to probe the frontier of the very small, and at scales where functionality depends on mere atoms, even the tiniest flaw matters. Researchers at Rice University have shown that hard-to-spot defects ...
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 / Turning over a new leaf in analyses of natural products
Scientists have developed a new way to help understand what happens in the body when people consume a plant product and the many chemicals it contains. The Journal of Natural Products published the method to quickly analyze ...
Phys.org / Undergrads expand the chemical toolbox for cancer drugs
Thanks to modern therapies, a cancer diagnosis is no longer an automatic death sentence. But many patients still suffer from unwanted side effects and limited efficacy. In a recent Bioconjugate Chemistry publication, William ...
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 / 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 ...
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 ...
