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 / Ultrathin membranes unlock nano-infrared views of biomolecules in water
Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: ...
Phys.org / The Mediterranean is getting warmer and saltier at an ever-faster pace—even thousands of meters below the surface
Across its basins and thousands of meters down, the Mediterranean Sea is getting warmer and saltier. Now, a new study finds it is also doing so at an increasingly rapid pace. The speedup is largest in the central and eastern ...
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 / Heating mica to 200°C reveals friction independent of sliding speed
Through joint research with the U.S. Geological Survey and the University of Tokyo, NIMS for the first time experimentally demonstrated friction completely independent of sliding velocity—an ideal that had never been realized—by ...
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 ...
Phys.org / New breeding approach targets crop rotations, not yield alone
Breeding crops for farming systems rather than yield alone could exploit untapped genetic potential and help farmers cut fertilizer bills.
Phys.org / The local costs of remote sensing: Examining the ethics of laser scanning in tropical forests
Laser scanning, often referred to as lidar, has rapidly transformed how tropical forest regions are studied, monitored and understood across academic disciplines. The technology enables researchers to peer through dense forest ...
Phys.org / Australia's ancient rainfall patterns more complex than previously believed
"Sediment and fossil records are a major pillar of our understanding of how the climate works—but climate scientists have gotten something wrong about Australia's ice age," says Dr. Alex F. Wall, lead author of a new research ...
Phys.org / 'Born-again' star offers rare chance to watch stellar evolution in real time
Astronomers have confirmed that one of the fastest-changing stars ever observed has entered a new stage of its evolution, offering a rare opportunity to watch a star's life unfold on human timescales.
Phys.org / Well-preserved tooth from Pacific mastodon found in a creek in San Francisco Bay Area
Brigid Lynch was working along a wooded creek in a mountainous part of the San Francisco Bay Area when something that didn't look like the rocks she'd been studying caught her eye. It turned out to be the fossilized tooth ...
Phys.org / Speeding glaciers drive half a century of polar ice loss
The longest satellite record ever assembled shows that Greenland and Antarctica have lost 11.3 trillion metric tons of ice since the 1970s, raising global sea level by more than 3 centimeters (1.2 inches)—and that most of ...
