Eocene ungulates were very selective in their feeding
A study by the UPV/EHU-University of the Basque Country into the paleodiet of extinct paleotheriidae (or pseudo horses) provides information about their feeding strategy and the environment they inhabited at the end of the Eocene. Plagiolophus was a.....»»
Great White feeding ground reveals shockingly low populations of famed shark
Perhaps no other ocean creature lives in the human imagination like the great white shark. But while great white sharks might be plentiful in the minds of beachgoers across the country, there are only a handful of places in the world where white shar.....»»
Selective mRNA degradation via autophagy: A novel role for autophagy in gene regulation
Optimal cell function requires a fine balance between the synthesis and degradation of biomolecules. Autophagy is the process by which cells degrade and recycle their own components, helping to clean up and maintain the cell's internal environment an.....»»
Study snapshot: Untested admissions
In undergraduate admissions, the adoption of test-optional policies at selective private institutions was linked to a 3-4 percent increase in enrollment of Pell Grant recipients, a 10-12 percent increase in enrollment of first-time Black, Latinx, and.....»»
Foliar application boosts the zinc content of wheat grain by up to 50%
A team from the Department of Agronomy at the UCO has demonstrated, through field tests carried out during 8 agricultural seasons, that foliar feeding with fertilizer increases the concentration of zinc in wheat more than if it is applied to the soil.....»»
Depositing iron species inside ZSM-5 to oxidize cyclohexane to cyclohexanone
The directly catalytic oxidation of alkanes has high atomic economy and application value to form corresponding chemical organic products such as alcohols, aldehydes, ketones and carboxylic acid. It is challenging to achieve efficient and selective o.....»»
Climate change is feeding our plants junk food
The human-led climate crisis has begun to impact our world in profound ways......»»
Study finds that offshore pile driving noise alters feeding behaviors of longfin squid
With the offshore wind industry expanding in the United States and elsewhere, a new study raises questions about how the noise from impact pile driving to install turbine supports can affect feeding behaviors of longfin squid, a commercially and ecol.....»»
Plasmonic nanoreactors regulate selective oxidation via energetic electrons and nanoconfined thermal fields
When optimizing catalysis in the lab, product selectivity and conversion efficiency are primary goals for materials scientists. Efficiency and selectivity are often mutually antagonistic, where high selectivity is accompanied by low efficiency and vi.....»»
Feeding cattle seaweed reduces their greenhouse gas emissions 82 percent
A bit of seaweed in cattle feed could reduce methane emissions from beef cattle as much as 82 percent, according to new findings from researchers at the University of California, Davis. The results, published today in the journal PLOS ONE, could pave.....»»
For migrating elephant seals, "lightscapes of fear" shape feeding, resting strategies
Every year in May, female elephant seals leave the beaches in California where they gave birth, nursed young, and molted, to embark on a seven-month foraging migration across the North Pacific Ocean. There is danger in the open ocean, however, and th.....»»
Solar cells: Losses made visible on the nanoscale
Solar cells made of crystalline silicon achieve peak efficiencies, especially in combination with selective contacts made of amorphous silicon (a-Si:H). However, their efficiency is limited by losses in these contact layers. Now, for the first time,.....»»
How filter-feeding bivalves could be used to clean up microplastics
On a hot summer day in Connecticut, it's common to go to a beach-side restaurant, eat some fresh oysters and mussels, and enjoy the crashing of the waves against the sand. For a group of University of Connecticut faculty and a Florida Atlantic Univer.....»»
Coronavirus pandemic restrictions can help or hinder schoolchildren with anxiety disorders
Parents fear children stuck at home for almost a year during the coronavirus pandemic, will lose critical social skills. And children with selective mutism, a severe form of anxiety, will lose even more......»»
Researchers design a new highly-selective tool to study "undruggable" proteins through the sugars they depend on
Sugar has been called "evil," "toxic," and "poison." But the body needs sugars, too. Sugar molecules help cells recognize and fight viruses and bacteria, shuttle proteins from cell to cell, and make sure those proteins function. Too much or too littl.....»»
Fossilized feeding frenzy: 47-million-year-old fly found with a full belly
An international team of scientists with Fridgeir Grímsson from the University of Vienna has found a previously unknown fossil fly species in old lake sediments of the Messel Pit, a UNESCO World Heritage Site in Germany. In the stomach of the fossil.....»»
Long-accepted theory of vertebrate origin upended by fossilized fish larvae
A new study out of the University of Chicago, the Canadian Museum of Nature and the Albany Museum challenges a long-held hypothesis that the blind, filter-feeding larvae of modern lampreys are a holdover from the distant past, resembling the ancestor.....»»
Supplementary feeding changing reindeer behavior and reindeer husbandry culture
Changing land use and the changing climate have both contributed towards supplementary feeding of reindeer becoming an established practice in the reindeer husbandry areas of Finland, Sweden and Norway. According to a recent Nordic research report, s.....»»
An astronaut"s guide to out-of-Earth manufacturing
mprovising new stuff from the stuff you have is part of an astronaut's job description—think Apollo 13's crew refitting CO2 filters to save their own lives, or stranded Mark Watney in The Martian, feeding himself on the Red Planet. Now plans are un.....»»
Oceans were stressed preceding abrupt, prehistoric global warming
Microscopic fossilized shells are helping geologists reconstruct Earth's climate during the Paleocene-Eocene Thermal Maximum (PETM), a period of abrupt global warming and ocean acidification that occurred 56 million years ago. Clues from these ancien.....»»
BCAS3-C16orf70 complex is a new actor on the mammalian autophagic machinery
Autophagy is an intracellular degradation process of cytosolic materials and damaged organelles. Researchers at Ubiquitin Project of TMIMS have been studying the molecular mechanism of mitophagy, the selective autophagy process to eliminate damaged m.....»»
