Phys.org / Consistency check casts doubt on evolving dark energy
Cosmologists have long struggled to determine whether the universe's accelerating expansion is being driven by a simple cosmological constant, or whether dark energy's influence is evolving over time. In a new analysis published ...
Phys.org / Developing seed atlas uncovers active genes tied to crop resilience and nutrition
Seeds like wheat, rice, and corn are at the center of the global food supply and provide most of the daily calories consumed worldwide. But despite their importance, scientists still do not fully understand many of the basic ...
Phys.org / Discovery of new fossils in Northwest Canada changes view of early animal evolution
Researchers have uncovered a remarkable fossil site in a remote part of Canada's Northwest Territories, offering unprecedented insight into the earliest evolution of complex animal life on Earth. Findings from the site represent ...
Medical Xpress / A brief kidney crisis in childhood can cast a long shadow over health for years afterward
Acute kidney injury (AKI) is a condition in which the kidneys suddenly lose their ability to filter waste from the blood. Developing within hours or days, AKI can cause dangerous waste accumulation and disrupt the body's ...
Phys.org / Less low cloud cover lets in more heat from the sun—and may lock in centuries of sea level rise
According to NOAA, the global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. The rate at which the sea level is rising is increasing, threatening coastal cities and ecosystems around the world.
Phys.org / How Earth recycles continents deep underground
Scientists have uncovered new evidence that Earth's continents are continuously reworked deep beneath the surface, offering fresh insight into how continents have evolved over billions of years.
Phys.org / Capturing an elusive step in molecular sandwich making
Since their discovery in the 1950s, metallocenes—chemical compounds where a metal atom sits "sandwiched" between two carbon rings—have been at the heart of organometallic chemistry research, finding applications in catalysis, ...
Medical Xpress / Early warning signs: Poor grip strength linked to greater odds of developing depression
Handgrip strength is the maximum force a person can apply with their hand, and it is often used as a proxy for overall muscular strength, functional capacity, and aging. Scientists have found that it can also be an indicator ...
Science X / Seen from Mars, an interstellar visitor looks completely different and changes what astronomers thought they knew
Last fall, a Chinese spacecraft orbiting Mars captured images of a comet from another star system, offering scientists a fresh vantage on a rare visitor.
Medical Xpress / AI atlas reveals hidden whole-body-damage caused by obesity
Obesity affects far more than metabolism and fat storage. It alters immune activity, nerve structure, and tissue organization across multiple organ systems, increasing the risk of diseases including type 2 diabetes, cardiovascular ...
Phys.org / Hellish Venus-like planets may be more prevalent than true exoEarths
Preliminary results of a study presented at the recent European Geosciences Union General Assembly in Vienna indicate that hellish Venus-type planets may be about twice as common as habitable planets that form with oceans.
Phys.org / 129,000 years of crocodiles: What we know about Australasia's ancient apex predators
The sight of a saltwater crocodile basking on a mudbank is one of the most iconic and intimidating images of northern Australia. Yet the crocodiles that inhabit the region today are just the survivors of a much richer and ...
