Phys.org / Tiny Mars's big impact on Earth's climate: How the red planet's pull shapes ice ages
At half the size of Earth and one-tenth its mass, Mars is a featherweight as far as planets go. Yet new research reveals the extent to which Mars is quietly tugging on Earth's orbit and shaping the cycles that drive long-term ...
Phys.org / A new valve for quantum matter: Steering chiral fermions by geometry alone
A collaboration between Stuart Parkin's group at the Max Planck Institute of Microstructure Physics in Halle (Saale) and Claudia Felser's group at the Max Planck Institute for Chemical Physics of Solids in Dresden has realized ...
Phys.org / Tissue repair slows in old age. These proteins speed it back up
As we age, we don't recover from injury or illness like we did when we were young. But new research from UCSF has found gene regulators—proteins that turn genes on and off—that could restore the aging body's ability to ...
Phys.org / Overlooked decline in grazing livestock brings risks and opportunities
For decades, researchers have focused on the problem of overgrazing, in which expanding herds of cattle and other livestock degrade grasslands, steppes and desert plains. But a new global study reveals that in large regions ...
Phys.org / 'Death by a thousand cuts': Pablo's galaxy ran out of fuel as black hole choked off supplies
Astronomers have spotted one of the oldest "dead" galaxies yet identified, and found that a growing supermassive black hole can slowly starve a galaxy rather than tear it apart.
Phys.org / El Niño and La Niña synchronize global droughts and floods, study finds
Water extremes such as droughts and floods have a huge impact on communities, ecosystems, and economies. Researchers with The University of Texas at Austin have turned their attention to tracking these extremes across Earth ...
Phys.org / The cosmic seesaw: Black holes eject material as winds or jets, but not both at once
Astronomers at the University of Warwick have discovered that black holes don't just consume matter—they manage it, choosing whether to blast it into space as high-speed jets or sweep it away in vast winds.
Phys.org / Robotic nanoprobe enables precise extraction of a single mitochondrion from a living cell
Mitochondrial dysfunction is associated with various chronic diseases and cancers, including neurodegenerative diseases and metabolic syndrome. Gently extracting a single mitochondrion from within a living cell—without ...
Phys.org / Designer enzyme enables yeast to produce custom fatty acids, reducing need for palm oil
Whether they are laundry detergents, mascara, or Christmas chocolate, many everyday products contain fatty acids from palm oil or coconut oil. However, the extraction of these raw materials is associated with massive environmental ...
Phys.org / Yeast DNA changes reveal hidden triggers for cancer-linked chromosome chaos
Changes in genes have been linked to the development of different diseases for a while. However, it's not exactly clear what the mechanisms, or the causes behind those specific genetic changes, are. Recent studies using fission ...
Phys.org / How E. coli exploit fluid flow and channel shape to swim upstream and cause infections
"The UN estimates that by 2050, common bacterial infections could kill more people than cancer," says Arnold Mathijssen, a biophysicist at the University of Pennsylvania who studies how active particles like bacteria move ...
Phys.org / Surface ceramics reveal self-sufficient rural economy in Ancient Samos
An international team of researchers has uncovered hidden clues about life in the hills of ancient southwest Samos, Greece.
