Phys.org / Are cats 'vegan' meat eaters? Why isotopic signatures of feline fur could trick us into thinking that way
Cats—unlike humans—are true carnivores: they must eat meat to survive because their bodies can't draw some essential nutrients from plants. By looking at tissues, researchers can get a good understanding of what foods ...
Medical Xpress / Two in five cancers worldwide are likely preventable, says new research
Nearly 40% of new cancer cases worldwide in 2022 may be associated with modifiable risk factors, according to an analysis of 36 cancer types from 185 countries. The findings suggest that reducing exposures such as tobacco ...
Medical Xpress / Pandemic disruptions to health care worsened cancer survival, study suggests
During the early years of the COVID-19 pandemic, experts worried that disruptions to cancer diagnosis and treatment would cost lives. A new study suggests they were right.
Phys.org / Removing livestock from grasslands could compromise long-term soil carbon storage
Removing sheep and other livestock entirely from upland grasslands—a strategy often promoted as a way to boost carbon storage and tackle climate change—may actually reduce the most stable forms of soil carbon, according ...
Medical Xpress / 'Missing link' protein key to restoring disorganized blood vessels
Blood flows around the body through a complex network of vessels, which must constantly adapt to changing needs. The balance between growing new vessels and stabilizing existing vessels, so they aren't leaky, must be finely ...
Phys.org / Urban light pollution disrupts nighttime melatonin in wild nurse sharks
Artificial light from major coastal cities can disrupt the nighttime biology of sharks, according to new research that provides the first-ever measurements of melatonin—a hormone tied to biological rhythms—in wild sharks.
Phys.org / Ancient American pronghorns were built for speed
The fastest land animal in North America is the American pronghorn, and previously, researchers thought it evolved its speed because of pressure from the now-extinct American cheetah. But recently, that theory has come under ...
Tech Xplore / Unhackable metasurface holograms: Security technology can lock information with light color and distance
A research team led by Professor Junsuk Rho at POSTECH (Pohang University of Science and Technology) has developed a secure hologram platform that operates solely based on the wavelength of light and the spacing between metasurface ...
Phys.org / AI accelerates access to insect collections
Researchers at the Museum für Naturkunde Berlin, together with data scientists, have developed a new method to largely automate the extraction of label information from digitized insect specimens. The pipeline, named ELIE, ...
