Phys.org / A famous galaxy's black hole has been hiding its most violent behavior

Astronomers have found that a nearby galaxy's black hole is blasting out a far more powerful and hidden gas outflow than previously realized. Studying NGC 1068, a well-known galaxy with an actively feeding black hole at its ...

Phys.org / Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show

When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, ...

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: ...

Medical Xpress / 'Momnesia' is real—scientists find a biological explanation for temporary forgetfulness during pregnancy

Many women say the same thing during pregnancy: They walk into a room and forget why, misplace their keys or struggle to follow a conversation. This phenomenon, often called "pregnancy brain" or "momnesia," has long lacked ...

Phys.org / Engineers solve puzzle of Arctic sea ice movement

Arctic sea ice moves and spreads in ways that wind alone cannot explain. A new UC Riverside-led study finds that collisions between individual pieces of ice provide a surprisingly simple explanation for these movements, potentially ...

Medical Xpress / Metabolite buildup reveals how aggressive brain tumors activate nearby neurons

Virtually all high-grade, aggressive gliomas in adults accumulate massive amounts of a metabolite called guanidinoacetate (GAA) that overstimulates nearby neurons and promotes tumor growth, according to new research from ...

Medical Xpress / Early changes in the tumor environment may explain why immunotherapy works for some patients but not others

Two patients receive the same immunotherapy for the same cancer. In one, the tumor retreats and stays gone for years. In the other, the treatment does nothing. Oncologists still have no reliable way to tell these patients ...

Medical Xpress / New test could dramatically speed diagnosis of hard-to-detect lung infections

A little-known chronic lung disease is silently emerging as a growing public health threat in the U.S. and around the world. Nontuberculous mycobacteria—a group of 200 known environmental bacteria found in soil and water, ...

Phys.org / Fungi neutralize spruce defense mechanisms with sugar

A research team at the Max Planck Institute for Chemical Ecology discovered a previously unknown strategy by which certain fungi neutralize spruce defense compounds. These fungi are introduced into trees by bark beetles, ...

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 / Muon rings enable precise calibration of telescopes at the Cherenkov Telescope Array Observatory

Research initiated as part of a bachelor's thesis in physics at the Universitat Autònoma de Barcelona (UAB) has culminated in a new analytical description of the muon-based calibration of dual-mirror Cherenkov telescopes. ...
