Phys.org / Microbes make microplastics more likely to form ice in clouds, research reveals
Tiny pieces of plastic, called microplastics, are showing up everywhere, even in the water in clouds, rain, and snow—and they may be affecting our weather and temperatures. A study published in Environmental Science & Technology ...
Phys.org / DNA analysis reveals two Hirondellea amphipods range farther and deeper than known
Two deep-sea amphipod species have been found to live in both hemispheres and share features, according to a new study that boosts our understanding of the biodiversity and evolutionary processes shaping deep-sea ecosystems. ...
Phys.org / Courting the competition: Some male fruit flies serenade each other rather than fight
Like the males of many animal species, male Drosophila melanogaster fruit flies, a commonly studied lab animal, are aggressive toward one another and even fight when competing for resources such as food and females. Researchers ...
Phys.org / Sea creatures reveal the physics behind animal body shape diversity
Animals come in an extraordinary range of body shapes. A starfish looks nothing like an earthworm, a mouse, or a human. Yet even closely related species can appear radically different: corals, jellyfish, and sea anemones ...
Phys.org / Chemo-optogenetic tool uses vitamin B₁₂ and green light to precisely regulate cell communication
Researchers at The Hong Kong University of Science and Technology (HKUST) have developed CarGAP, a chemo-optogenetic tool that uses vitamin B₁₂ and green light to precisely control gap junctions, the microscopic channels ...
Phys.org / How clonal raider ants update their friend-or-foe recognition
For ants, the ability to instantly distinguish nestmates from outsiders who might hijack the colony is crucial. Now, a new study shows that the system that ants use to determine who belongs in the colony is far more flexible ...
Phys.org / Moss-associated nitrogen fixation helps sustain plant growth in warming permafrost ecosystems
Climate warming can increase plant growth in permafrost regions by lengthening the growing season, speeding up plant metabolic processes, and allowing deeper root penetration as permafrost thaws. However, the capacity for ...
Phys.org / Cells in the mosquito's gut drive its appetite, research shows
Researchers have known for decades that female mosquitoes—the ones responsible for the itchy and irritating bites that can also transmit disease—lose their desire to bite humans for several days after feeding, as they ...
Phys.org / Low-cost test dissolves threat of fake drugs
Fake news can be tricky to spot, but spotting fake drugs just got a little easier. Researchers have devised a low-cost way to help distinguish legitimate medications from counterfeit ones.
Phys.org / 'Plastic-eating' fusion enzyme improves polyester textile recycling
In a new study, scientists from the universities of Portsmouth and Manchester report that a specially engineered enzyme can significantly speed up the breakdown of PET—the plastic used in water bottles, food packaging and ...
Phys.org / Pompeii's battle scars linked to an ancient 'machine gun'
The ancient city of Pompeii is one of those archaeological sites that keeps on giving with one discovery after another. While much of what we know about the Roman settlement comes from the eruption of Vesuvius in AD 79, another ...
Phys.org / The discovery of a buried delta on Mars could boost the search for life
There's more evidence that water once flowed on Mars with the discovery of an ancient river delta deep below the surface. NASA's Perseverance rover found it more than 35 meters beneath Jezero Crater using ground-penetrating ...
