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 / 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 / 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 / SpaceX prepares for first orbital flight of Starship rocket
SpaceX announced Tuesday that it was planning to send its flagship rocket, Starship, into orbit, a key step in its project to one day reach the moon or Mars.
Phys.org / Dogs show human-like brain activity when they restrain themselves
When we tell a dog "no" and it resists temptation, what happens in its brain? New research from the Department of Ethology at ELTE and the HUN-REN Research Centre of Natural Sciences suggests that dogs may do more than respond ...
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 / 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 / First-of-its-kind preventive phage therapy provides promising results against Salmonella
The mammalian gut microbiome teems with a delicate balance of bacteria and the viruses that keep them in check, called bacteriophages, or phages. Each bacterial species usually has its own set of phage partners.
Phys.org / Engineers solve puzzle of Arctic sea ice movement
Arctic sea ice moves and spreads in ways that wind alone cannot explain. A new UC Riverside-led study finds that collisions between individual pieces of ice provide a surprisingly simple explanation for these movements, potentially ...
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, ...
Phys.org / A 16-minute train delay shows how a solar storm disrupted Victorian technology
A 178-year-old mystery surrounding one of the earliest recorded examples of space weather affecting technology has been solved by an international team led by Lancaster University.
Phys.org / A world 20 light-years away reveals surprisingly organized, Jupiter-like weather
Scientists from Trinity College Dublin have developed a way to unravel changing weather patterns on distant worlds. Using this approach, they discovered that the weather on a well-studied brown dwarf, SIMP 0136, previously ...
