Phys.org / Scientists identify first non-coding gene that controls cell size
What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis behind cell size has ...
Phys.org / Rare brown dwarf discovered orbiting ancient star
Astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere report the discovery of a new brown dwarf about 60 times more massive than Jupiter. The newfound substellar object, designated TOI-7019 ...
Phys.org / Signature of climate change: Nearly half of harmful wildfire smoke exposure linked to human-caused warming
Across the western U.S., wildfires and the dangerous smoke that results have increased in frequency and intensity since the 1990s—that much is clear. Surprisingly less clear are the exact reasons why: While greenhouse gas-related ...
Phys.org / Vital intertwining: Blood parasite's chainmail-like DNA structure could inspire next-generation materials
As tough as medieval chainmail armor and as soft as a contact lens. This material is not taken from science fiction, it is a natural structure made of thousands of DNA circles interlinked with each other. Studying it can ...
Phys.org / Your body is full of medicine. Researchers can now synthesize it
Northeastern University researchers have made a breakthrough drug discovery, developing the first synthetic endogenous cannabinoid compound, with repercussions for new therapeutics from pain and inflammation to cancer.
Phys.org / AI and underwater recordings reveal bowhead whale breeding grounds in Arctic sea ice
If bowhead whales produce particularly varied and diverse calls in one area, it is very likely that the area is a breeding ground. The species occurs exclusively in the Arctic Ocean and is therefore endemic to this region.
Phys.org / Altermagnetism in RuO₂ thin films: A new magnetic material for the AI era
A research team has demonstrated that thin films of ruthenium dioxide (RuO₂) exhibit altermagnetism—the defining property of what is now recognized as the third fundamental class of magnetic materials.
Phys.org / Climate change's hidden price tag: A 12% drop in our present income
For decades, economists have focused on how climate change will impact the future. New research from Derek Lemoine, APS Professor of Economics in the Eller College of Management, shows the impact is already here: climate ...
Phys.org / A photographer finds thousands of dinosaur footprints near Italian Winter Olympic venue
A wildlife photographer stumbled upon one of the oldest and largest known collections of dinosaur footprints, dating back about 210 million years to the Triassic Period, high in an Italian national park near the 2026 Milan ...
Phys.org / Shaking magnets with ultrafast light pulses reveals surprising spin control
An international team of researchers led by Lancaster University has discovered a highly efficient mechanism for shaking magnets using very short light pulses, shorter than a trillionth of a second. Their research is published ...
Phys.org / Storms reveal how marine snow shapes carbon flow in the deep ocean
In the midst of the COVID pandemic, scientists embarked on an ambitious research expedition to the North Atlantic to investigate the inner workings of the ocean's carbon cycle. A series of storms hammered the three vessels, ...
Phys.org / People tend to overestimate others' emotions, but this may boost empathy
According to a new study led by Prof. Anat Perry and her Ph.D. student, Shir Genzer, of the Hebrew University of Jerusalem, together with Prof. Noga Cohen from the University of Haifa, chances are you're overestimating just ...
