Phys.org / DNA-binding protein blocks virulence cascade in a diarrhea pathogen outside hosts, study finds
Some pathogens use temperature as a trigger and activate virulence only after entering the warmer environment of a host. A research team from Ruhr University Bochum, Germany, and the University of Münster, Germany, investigated ...
Phys.org / Software package makes gene regulation easier to study—and tweak
Understanding how genes are switched on and off in specific cell types remains one of biology's central challenges. While AI has made major progress in decoding the regulatory logic of DNA, applying these approaches across ...
Phys.org / AI turns electron microscopy into materials insights in minutes
An electron microscopy image can capture atoms arranged in a crystal lattice or defects threading through a semiconductor material, but turning that image into materials insight can take weeks of careful analysis. Now, an ...
Phys.org / Protostars 'sneeze' and produce rings of gas and magnetic flux as they grow
Researchers have uncovered new insights into the early development of baby stars. As published in The Astrophysical Journal Letters, a research team from Kyushu University and Kagawa University reports that during the early ...
Phys.org / Microscopic coils and coffee trees lead to new fungal discovery
Yunnan Province in southwestern China is a global biodiversity hotspot, accommodating an incredible variety of plants and animals. It is also the heart of China's coffee industry, with Yunnan accounting for almost all of ...
Phys.org / Native Americans were making dice, gambling, exploring probability millennia before their Old World counterparts
A new study in American Antiquity presents evidence that the earliest known dice in human history were made and used by Native American hunter-gatherers on the western Great Plains more than 12,000 years ago at the end of ...
Phys.org / Unexplained sky flashes from the 1950s: Independent analysis supports their existence
Historical observations from an observatory in Germany have now independently verified evidence for brief, mysterious flashes of light in the night sky, first picked up by an American astronomical survey in the 1950s. Through ...
Phys.org / Gravitational waves as possible candidates for the origin of dark matter
Gravitational waves could be responsible for the production of dark matter during the early phases of our universe's formation, according to results of a new study by Professor Joachim Kopp from Johannes Gutenberg University ...
Phys.org / Thirty previously unpublished verses by Empedocles discovered on a papyrus from Cairo
A 2,000-year-old papyrus fragment, discovered in the archives of the French Institute of Oriental Archaeology in Cairo, reveals 30 previously unpublished verses by Empedocles, a pre-Socratic philosopher of the fifth century ...
Phys.org / Lakes forming next to Greenland's melting ice sheet are speeding up glacier flow
A growing network of meltwater lakes at the edge of the Greenland ice sheet is accelerating the flow of major glaciers, potentially increasing the pace of global sea-level rise. Warmer air and sea temperatures have led to ...
Phys.org / High nickel concentrations in Martian bedrock point to potential biosignatures
In 2024, NASA's Perseverance rover found surprising levels of Nickel in the Martian bedrock of an ancient river channel, called Neretva Vallis, which flowed into the Jezero crater. A new study, published in Nature Communications, ...
Phys.org / Gravitational waves suggest a 'forbidden zone' for stellar-origin black holes
An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive ...
