Phys.org / Ushikuvirus: Newly discovered giant virus may offer clues to the origin of life
The origin of life on Earth becomes even more fascinating and complex as we peer into the mysterious world of viruses. Said to have existed since living cells first appeared, these microscopic entities differ greatly from ...
Phys.org / CRISPR discovery could lead to single diagnostic test for COVID, flu, RSV
Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to disable and modify genes, ...
Phys.org / Urban atmosphere acts as primary reservoir of microplastics, researchers find
Over the past two decades, microplastics (MPs) and nanoplastics (NPs) have been recognized as emerging pollutants, detected across every environmental compartment of Earth's system—the atmosphere, hydrosphere, lithosphere, ...
Phys.org / Long day at work? Go ahead and watch some TV, research suggests
Brain dead after a hard day of work? It turns out it's totally fine to park yourself in front of the TV. It might even make recovery—an essential part of burnout prevention—easier.
Phys.org / Sandblasting on Mars: Camera reveals how prevailing winds shape elongated landforms in volcanic zone
Martian winds can have quite an impact. ESA's Mars Express has spotted them whipping up sand grains and acting as a cosmic sandblaster, carving out intriguing grooves near Mars's equator.
Phys.org / How a parasite 'gave up sex' to find more hosts—and why its victory won't last
Australian researchers have uncovered how a particular strain of a diarrhea-causing parasite managed to infect more animal species, offering new insights into how parasitic infections emerge and spread to people.
Phys.org / Inflatable fabric robotic arm picks apples
A low-cost, simple robotic apple picker arm developed by Washington State University researchers may someday help with fruit picking and other farm chores.
Phys.org / Sentinel-1's decade of essential data over shifting ice sheets
The extent and speed of ice moving off the ice sheets of Greenland and Antarctica into the sea—an important dynamic for climate and sea-rise modeling—has been captured over a 10-year period by satellites from the Copernicus ...
Phys.org / Stars that die off the beaten path
Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, opening a new window into how exploding stars shape the cosmos. Focusing on M33, a spiral galaxy about ...
Phys.org / Small chimps, big risks: What chimps show us about our own behavior
The riskiest behavior in humans peaks in adolescence. Researchers from the University of Michigan and James Madison University expected to find risky behavior to peak in adolescence in a study of chimpanzees as well. But ...
Phys.org / You've heard of climate change. What is the climate debt doom loop?
Municipal bonds are a time-honored way to fund roads, schools, bridges and other public projects while paying investors interest, usually at tax-free rates.
Phys.org / How rice viruses manipulate plant defenses to protect insect vectors
Planthoppers and leafhoppers not only feed on rice plants but also act as highly efficient vectors for plant viruses, causing substantial yield losses worldwide. Notably, their persistent ability to evade natural enemies ...
