May 21, 2025 Biologists recently announced that they have released the first broad scale, comparative, fine-grained analysis linking the amplitude, or volume, of a birds' song to its vocal frequency, or pitch. Though biologists have long wondered whether birds are able to control their pitch as they get louder or if their vocal abilities are mechanically limited, until now there has been no wide-ranging data ...

May 20, 2025 Proteins are among the most studied molecules in biology, yet new research shows they can still hold surprising secrets. Researchers have discovered previously undetected chemical bonds within archived protein structures, revealing an unexpected complexity in protein chemistry. These newly identified nitrogen-oxygen-sulphur (NOS) linkages broaden our understanding of how proteins respond to ...

May 19, 2025 Researchers have discovered a new way to reduce obesity. Supplying the gut with extra acetate reduces fat and liver mass in both normal and obese mice, as long as bacteria of the Bacteroides species is also present. When both these conditions are met, gut bacteria can eliminate more sugars from the gut and promote the burning of fats for energy in the ...

May 9, 2025 As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the structure of oxygen vacancies in perovskite oxide catalysts, the researchers successfully reduced the reaction temperature from 80-150 C to nearly 30 C, ...

May 20, 2025 The Arctic is one of the coldest places on Earth, but in recent decades, the region has been rapidly warming, at a rate three to four times faster than the global average. However, current climate models have been unable to account for this increased pace. Now, researchers have reported that clouds may be to ...

May 20, 2025 Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. The research not only adds a facet to possible evolutionary strategies, but also lends weight to Darwin's suspicion that this strategy might be a path to ...

May 20, 2025 African elephants are the largest land animals on earth and significantly larger than their relatives in Asia, from which they are separated by millions of years of evolution. Nevertheless, Asian elephants have a 20 percent heavier brain, as scientists were able to demonstrate. They also showed that elephant brains triple in weight after birth. These results provide potential explanations for ...

May 20, 2025 Using synchrotron X-ray nanotomography with detailed 3D imaging and in-situ mechanical testing, researchers are peering inside shark skeletons at the nanoscale, revealing a microscopic 'sharkitecture' that helps these ancient apex predators withstand extreme physical demands of constant motion. After hundreds of millions of years of evolution, scientists can now finally see how shark cartilage ...

May 20, 2025 To better understand the circadian clock in modern-day cyanobacteria, a research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, and KaiC (Kai-proteins) in modern cyanobacteria, comparing it to the function of ancestral Kai ...
