An international collaborative study involving researchers from Massey University, the University of Canterbury, NIWA, and Flinders University has analyzed the isotopic niche of 21 species of toothed whales in New Zealand.

Knowing the structure of a complex biological system isn't nearly enough to understand how it works. It helps to know how the system moves.

Understanding the busy networks inside our cells can help researchers develop new cancer treatments and prevent dangerous fungal infections.

Six of NASA's SunRISE small satellites will work together, creating the largest radio telescope ever launched to detect and track hazardous explosive space weather events.

Scientists using sophisticated computational chemistry techniques have identified a new pathway for how sulfur particles can form in the atmosphere of Venus. These results may help to understand the long sought-after identity of the mysterious ultraviolet absorber on Venus.

Space may look empty, but it contains extreme temperatures, high levels of background radiation, micrometeoroids, and the unfiltered glare of the sun. In addition, materials and equipment on the outside of the International Space Station are exposed to atomic oxygen (AO) and other charged particles as it orbits the Earth at the very edge of our atmosphere. Only the hardiest materials, equipment, and organisms can withstand this harsh environment, and scientists conducting research on the orbiting... Читать дальше...

For the first time, researchers successfully captured CT images of an entire wooly mammoth tusk, according to a new "Images in Radiology" article published in the journal Radiology. Researchers were able to do a full scan of the tusk in its entirety—or in toto—using a newer clinical CT scanner. The new technology allows for large-scale imaging without having to do multiple partial scans.

Banana peels aren't always destined for the trash or compost anymore. They're making their way onto people's plates, replacing pork in "pulled peel" sandwiches and getting fried up into "bacon." And now, researchers reporting in ACS Food Science & Technology show that incorporating banana peel flour into sugar cookie batter makes the treats more healthful. In taste tests, cookies enriched with some banana peel flour were more satisfying than those baked with wheat flour alone.

Guides suggest some species are better than others for pollinators, but when you get to the plant nursery you're confronted by half a dozen cultivars of the same species. How do you pick between them?

Microorganism-free enzyme-based reaction systems are now used for the production of hydrogen, bioelectricity, and useful biochemicals. In these biosystems, raw materials called substrates are broken down by a series of enzymes (i.e., biological catalysts) to obtain the desired end-product. In several cases, the substrates are carbohydrates such as sucrose, cellulose, or starch. In the first step of these reactions, sucrose is converted to glucose derivatives like ɑ-glucose 1-phosphate (ɑ-G1P) or glucose 6-phosphate (G6P)... Читать дальше...

In late May of 2021, 172 runners set out to tackle a 100-kilometer (62-mile) ultramarathon in northwestern China. By midday, as the runners made their way through a rugged, high-elevation part of the course, temperatures plunged, strong winds whipped around the hillslopes and freezing rain and hail pummeled the runners. By the next day, the death toll from the sudden storm had risen to 21.

A new research paper was published in Oncotarget on August 3, 2022, entitled, "A novel mechanism of regulation of the oncogenic transcription factor GLI3 by toll-like receptor signaling."

Although some researchers have identified peptides through multiple methods, as in Arabidopsis and maize, the biological functions of most non-conventional peptides (NCPs) remain to be demonstrated. NCPs function by modulating larger regulatory proteins, and their functions can therefore be predicted from the proteins on which they act. In addition, the functions of NCPs can also be predicted by genome-wide association studies, such as the combination of NCPs with quantitative trait locus (QTL) or domestication analysis.

Most of us have felt the shock from static electricity by touching a metallic object after putting on a sweater or walking across a carpet. This occurs as a result of charge build-up whenever two dissimilar materials (such as our body and the fabric) come in contact with each other.

Phytoplankton is the foundation of all life on the planet. Understanding how these photosynthetic organisms react to their ocean environment is important to understanding the rest of the food web.

New research has found there are significant differences in the earnings between white and ethnic minority workers who are colleagues in the same workplace.

The tropical forests of the Western Ghats, a vast mountain range in Western India, are home to many diverse species, especially endemic ones. In a recent study, published in the journal Molecular Phylogenetics and Evolution, researchers at the LIB have for the first time analyzed the distribution of pseudoscorpions (an arachnid group) in this region in the light of geo-climatic fluctuations and continental drift, providing evidence of ancient species lineages.

A new study from North Carolina State University explores the connection between hearing loss and dementia in geriatric dogs. The work could aid in both treatment of aging dogs and in understanding the relationship between sensory loss and cognitive function in dogs.

An online database developed at the University of Sussex which documents pollinator-plant interactions, could help the public understand how to plant for pollinators and support biodiversity.

French marine experts will attempt Tuesday to rescue a beluga whale that swam up the Seine river and return it to the sea, officials said, a complex and risky operation for an animal already sick and malnourished.

Nature strives for chaos. That's a nice, comforting phrase when yet another coffee cup has toppled over the computer keyboard and you imagine you could wish the sugary, milky brew back into the coffee cup—where it had been just seconds before. But wishing won't work. Because, as mentioned, nature strives for chaos.

Every 60 seconds the equivalent of a truckload of plastic enters the global ocean. Where does it end up? Right now, researchers simply don't know. But in a bid to help find out, an ESA-led project developed floating transmitters whose passage can be tracked over time, helping in turn to guide a sophisticated software model of marine plastic litter accumulation.

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.

New research describes food systems designed not by the logic of growth such as efficiency and extraction, but by principles of sufficiency, regeneration, distribution, commons, and care. It argues that food systems can instead be the foundation of healthy communities, ecologies and economies.

About 15 years ago, a group of researchers discovered mutant zebrafish. The eyes of these zebrafish did not develop correctly, resulting in significantly smaller eyes than those of wild zebrafish. Now, one of these researchers—Prof. Ichiro Masai—who leads the Developmental Neurobiology Unit at the Okinawa Institute of Science and Technology (OIST), alongside his former Ph.D. student Dr. Swathy Babu, has used this mutation to understand the role of a protein in preventing cell death. This could have... Читать дальше...
