Phys.org / New findings challenge idea that human bodies simply got bigger and bigger over time in a steady line
The biggest jump in body size among our ancestors happened around 2–2.5 million years ago, with the appearance of Homo rudolfensis or Homo erectus/ergaster, rather than gradually across the whole human family tree.
Medical Xpress / Why pollution affects some asthma patients more than others
For many people with asthma, air-quality advisories are harbingers of worsening symptoms. But for reasons science has struggled to explain, the extent to which pollution exacerbates asthma varies widely from person to person.
Phys.org / Images: Perseverance reaches 'marathon' milestone on Mars
NASA's Perseverance rover appears as a green speck on the Martian surface on June 13, 2026, a day before the robotic explorer marked a distance milestone, having traveled a full marathon (26.2 miles, or 42.195 kilometers) ...
Medical Xpress / Can AI be your therapist?: Q&A with an expert
More than a third of psychologists report having patients who use artificial intelligence as an additional source of mental health support. As more people turn to AI for advice, companionship and help navigating difficult ...
Phys.org / Bird-derived gene tool inserts plant DNA 30 times more efficiently than CRISPR
In a rapidly changing climate landscape, the plants we rely on for food, textiles and more face a multitude of challenges, including rising temperatures, drought and disease. Caltech's Gözde Demirer, the Clare Boothe Luce ...
Phys.org / Image: Roman Telescope arrives at Kennedy Space Center
In this photo from June 21, 2026, NASA's Nancy Grace Roman Space Telescope arrives at the agency's Kennedy Space Center in Florida aboard NASA's Pegasus barge. After offloading and transportation to the spaceport's Payload ...
Phys.org / Why warmer seas may not wipe out female fish in some species
In many fish species, water temperature determines the sex of the fry. This biological mechanism threatens to wipe out entire populations because of a shortage of females in the face of global warming. However, an international ...
Phys.org / Nanoparticles sneak antibodies into cells to inhibit cancer and inflammation
A delivery system that uses lipid nanoparticles to sneak proteins into cells can accomplish the same feat by smuggling therapeutic antibodies, new research has found.
Phys.org / How continental shelf seiches triggered flooding following New York and New Jersey hurricanes
In 1938 and 1944, two major hurricanes struck Long Island, and after the initial winds subsided, the surges came back unexpectedly hours later, leading observers to wonder whether this was a tsunami. In a study appearing ...
Phys.org / Four-decade mystery solved as PKCβ structure reveals new drug target
After nearly four decades of research, Mayo Clinic scientists have revealed the molecular structure of protein kinase C beta (PKCβ), a key protein linked to cancer and neurological diseases. The findings, published in Nature ...
Phys.org / New algorithm identifies disease-linked changes in cells without prior training
A new algorithm could drive breakthroughs in understanding cancer, Alzheimer's disease and other potentially fatal conditions. Researchers from the University of Waterloo developed the machine-learning algorithm, called RNovA, ...
Phys.org / Self-driving chemistry lab discovers catalysts that can switch products on demand
Researchers have developed a self-driving chemistry lab that can autonomously search through hundreds of catalyst recipes and reaction conditions to identify faster, more selective and more programmable ways to make important ...
