Phys.org / Brazilian sedge reproduces sexually but without DNA reshuffling, producing genetic clones
Sexual reproduction usually reshuffles genetic information, creating offspring that differ from their parents. But one small plant takes an unexpected route. In a new study published in Nature, an international team led by ...
Phys.org / Snow, monsoons and oceans shift Earth's center of mass each year, satellite tracking shows
Seasonal changes redistribute enough water around Earth to shift the planet's center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations ...
Phys.org / Why you really shouldn't overcook your proteins
The development of cooking was a major milestone in the evolution of human civilization because it made food easier to digest and more energy-efficient. Heating food can also kill harmful pathogens and make certain foods ...
Phys.org / Why do some chimpanzee mothers carry their dead infants for months?
Chimpanzee and bonobo mothers sometimes continue to carry their infants after they have died, a behavior known as infant corpse carrying (ICC). It is widely documented, and many explanations have been proposed, but few have ...
Phys.org / Iron, sulfur and purple light unlock greener carbon-carbon bond formation
Much of organic chemistry, including the type used to create and alter medicinal drugs, relies on modifying carbon bonds. Rice University's Julian West has been developing a less expensive, faster and more environmentally ...
Phys.org / Newfound 'baby' planet smashes record for youngest known world
Astronomers have confirmed a world less than a million years old as the youngest known planet, using data from archives. Called Elias 2-24 b, the baby planet is still whirling in its natal disk of dust and gas.
Phys.org / Tiny oyster larvae rely on gravity to feed
Eastern oyster larvae are only 100–300 micrometers long, but their dense calcium carbonate shells make them substantially heavier than the surrounding seawater. A new study led by the Woods Hole Oceanographic Institution ...
Phys.org / Thinking outside the binding site: Drug molecule makes a square peg fit a round hole
A square peg doesn't fit a round hole. But what if the peg could change the shape of the hole? A newly developed drug molecule can do something surprisingly similar when binding to its target protein, according to a University ...
Phys.org / AI struggles to decipher 'animal language' because sound doesn't equal meaning, experts say
In recent years, numerous attempts have been made to use artificial intelligence to decipher the communication of bats, whales, birds and other animals. However, a new study led by a team of researchers from Tel Aviv University ...
Phys.org / Bacterial invasion proteins could improve detection of live crop pathogens
Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State's College of Agricultural Sciences. The research—published ...
Phys.org / Compact optical screen could pave the way for cheaper infrared cameras
New research led by the ARC Center of Excellence for Transformative Meta-Optical Systems (TMOS) at the University of Melbourne demonstrates a new way to make invisible infrared light visible without relying on the expensive ...
Phys.org / Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show
When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, ...
