Phys.org / How migrating cells build their leading edge: Master regulator may resolve long-standing debate
The ability of cells to move and change position is essential for various processes in our bodies. Immune cells move to sites of action, epithelial cells migrate during wound closure, and neurons extend their axons for signal ...
Phys.org / Student-led missions deploy free-flying light sails from CubeSats in low Earth orbit
Students in Cornell's Space Systems Design Studio (SSDS) have released mission results for two unique light-sail experiments. These sails are slightly larger than a pizza box and harness momentum from photons to accelerate ...
Phys.org / As cities prepare for 2026's super El Niño, some crucial blind spots can't be ignored
This year's El Niño has the potential to be one of the strongest in living memory, and the evidence is showing up around the world.
Tech Xplore / Snapping rods let frog-like robot outrun rigid legs across six terrains
Roboticists at the UCLA Samueli School of Engineering and the University of Michigan have shown that elastic rods can be bent and twisted to repeatedly snap between shapes, releasing built-up energy that enables small robots ...
Medical Xpress / Social context matters when studying the genetics of social behavior
Social behavior is heritable but heterogeneous. A mother reporting on her toddler learning to share, a teacher observing a schoolchild navigating friendships and peer relations, and a teenager describing their own social ...
Phys.org / Inclusion is central to England's education policy—but what it means is changing
Inclusion has become one of the most prominent concepts in contemporary education policy in England. Its position at the center of the Department for Education's ambitions can be seen in recent guidance on the creation of ...
Phys.org / Does Tutankhamen's tomb hold his stepmother Queen Nefertiti's remains? New study offers tantalizing clues
When Tutankhamun's tomb was discovered over a century ago, it became an immediate worldwide sensation, revealing a wealth of treasures from ancient Egypt. In the decades that followed, the tomb was meticulously cleared, cataloged ...
Medical Xpress / Two protective genetic pathways may converge to reduce Alzheimer's disease risk
Alzheimer's disease is the most common form of dementia worldwide. Although the APOE ε4 allele is the strongest genetic risk factor for late-onset Alzheimer's disease, not all carriers develop dementia, indicating that other ...
Medical Xpress / RNA therapy may help preserve muscle during GLP-1 weight loss
GLP-1 drugs have revolutionized obesity treatment, but they can lead people to lose muscle mass along with fat. And when patients stop treatment, they often regain their weight—primarily as fat.
Phys.org / A newly discovered mechanism helps cells prevent errors during DNA replication
At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart muscle cells divide ...
Medical Xpress / Batteries that safely break down in the GI tract could improve ingestible devices
Using materials safe for human consumption, MIT researchers have created tiny batteries that could be used to power ingestible electronic devices. Such batteries could make the devices safer for patients and minimize the ...
Phys.org / New ligand design balances radical generation and catalyst regeneration for challenging chemical reactions
Radicals, atoms or molecules that readily react with other substances to form new bonds, are useful tools for building complex substances such as pharmaceuticals. But even when a radical is generated efficiently, the reaction ...
