Phys.org / Overlooked molecule points to new treatments for drug-resistant fungal infections
Fungal infections kill millions of people each year, and modern medicine is struggling to keep up. But researchers at McMaster University have identified a molecule that may help turn the tide—butyrolactol A, a chemical ...
Phys.org / Supernova remnant video from NASA's Chandra is decades in making
A new video shows the evolution of Kepler's Supernova Remnant using data from NASA's Chandra X-ray Observatory captured over more than two and a half decades.
Phys.org / Marine geoscientists link warming with ancient ocean 'salty blob'
Climate change has many culprits, from agriculture to transportation to energy production. Now, add another: the deep ocean salty blob.
Phys.org / Four baby planets show how super-Earths and sub-Neptunes form
Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune orbit most stars. Oddly, our sun lacks such a planet. That's been a source of frustration for planetary ...
Phys.org / Small-scale rainforest clearing drives majority of carbon loss, study finds
Think of the destruction of Earth's rainforests and a familiar image may come to mind: fires or chainsaws tearing through enormous swaths of the Amazon, releasing masses of planet-warming carbon dioxide.
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 / 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 / Boosting the cell's own cleanup: New class of small molecules accelerate natural protein degradation
Cells have a remarkable housekeeping system: Proteins that are no longer needed, defective, or potentially harmful are labeled with a molecular "tag" and dismantled in the cellular recycling machinery. This process, known ...
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 / 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 / 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 ...
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.
