Researchers have characterized changes in the structure of motor proteins, called myosins, and energy consumption that occur during hibernation, highlighting key differences in large and small hibernators.
Rain Comes to the Arctic, With a Cascade of Troubling Changes
In August of 2021, rain fell atop the 10,551-foot summit of the Greenland ice cap, triggering an epic meltdown and a more-than-2,000-foot retreat of the snowline.
Microplastics found in every human placenta tested
Researchers reported finding microplastics in all 62 of the placenta samples tested, with concentrations ranging from 6.5 to 790 micrograms per gram of tissue.
Even Very Low Levels of Pesticide Exposure Can Affect Fish for Generations, Study Finds
Fish exposed to some pesticides at extremely low concentrations for a brief period of time can demonstrate lasting behavioral changes, with the impact extending to offspring that were never exposed firsthand, a recent study found.
Spartans Introduce a Big New Idea With the Help of Tiny Plankton
Researchers at Michigan State University and the Carnegie Institution for Science have developed a model that connects microscopic biology to macroscopic ecology, which could deepen our understanding of nature’s laws and create new opportunities in ecosystem management.
America’s Sinking East Coast
In many parts of the U.S. East Coast, rising seas driven by melting ice and the thermal expansion of warming water is only part of what threatens coastal areas.
Mystery solved: The oldest fossil reptile from the alps is an historical forgery
Palaeontological analysis shows renowned fossil thought to show soft tissue preservation is in fact just paint. Fossil discovered in 1931 was thought to be an important specimen for understanding early reptile evolution. While not all of the celebrated fossil is a forgery, scientists urge caution in how the fossil is...
Advanced artificial photosynthesis catalyst uses CO2 more efficiently to create biodegradable plastics
A research team that had previously succeeded in synthesizing fumaric acid using bicarbonate and pyruvic acid, and carbon dioxide collected directly from the gas phase as one of the raw materials, has now created a new photosensitizer and developed a new artificial photosynthesis technology, effectively doubling the yield of fumaric...
Environmental monitoring offers low-cost tool for typhoid fever surveillance
Researchers can accurately track where typhoid fever cases are highest by monitoring environmental samples for viruses called bacteriophages that specifically infect the bacterium that causes typhoid fever.
What can bulls tell us about men?
Researchers have found genes in the reproductive organs of bulls that influence fertility. The findings can be transferred to humans, as these genes are also present in men.
