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 / Urine tests confirm alcohol consumption in wild African chimpanzees
Aleksey Maro knows far more than he cares to know about the urination habits of chimpanzees. But if you want to measure the alcohol intake of chimps in a Ugandan rain forest, where a breathalyzer is impractical, collecting ...
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 ...
Tech Xplore / Protecting perovskite solar cells against environmental influences with light-switchable molecules
A team from the University of Stuttgart, together with international researchers, has succeeded in enhancing both the efficiency and environmental resilience of perovskite solar cells. This is another important step toward ...
Medical Xpress / More sensitive HIT cell therapy shows promise against solid cancers
CAR T cell therapy has revolutionized the treatment of many blood cancers, but has shown little success against solid tumors, which account for over 85% of all cancers. Columbia researchers have now found that a new type ...
Phys.org / Major gap in Earth's rock record likely due to tectonics—not glaciers
The Great Unconformity is a major gap in Earth's geologic record. The missing layer between Precambrian and Cambrian rocks represents a gap of around a billion years of history. Among much debate surrounding the cause of ...
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 / 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 ...
Medical Xpress / New atlas maps how aging reshapes cells across the entire mammalian body
As we age with each passing year, we become more susceptible to chronic diseases like cancer, heart disease, and dementia. Scientists have long focused on fighting these conditions one at a time. Recently, however, many have ...
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 / Thunderstorms conjure ghostly coronae in treetops, observed outdoors for the first time
For the first time, researchers have observed and measured weak electrical discharges, known as coronae, on trees during thunderstorms. A new study describes the near-invisible sparkles appearing similarly on branches of ...
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 ...
