Phys.org / Fossils from Wyoming's Smiley Draw deepen understanding of early primate evolution
A new study from the University of Kansas complicates the picture of primates living in North America some 55 million years ago during the Eocene, a warm period that allowed mammals to diversify quickly.
Phys.org / Ant teams beat gravity-based puzzle solvers
Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial ...
Phys.org / Cannabis farming is changing streams in California, experts warn
Groundwater pumped to irrigate cannabis crops in California's Emerald Triangle can cause some streams that normally run year-round to dry up entirely during summer, say researchers from Simon Fraser University, the University ...
Medical Xpress / Researchers discover immune 'off switch' used by cancer cells
Mayo Clinic researchers have identified a protein that cancer cells use to shut down the body's immune response, a discovery that could help scientists develop new treatments that make cancer immunotherapies more effective.
Phys.org / Simulations hint at a hidden population of companionless black holes
So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...
Medical Xpress / Social media algorithms expose many adolescents to self-harm content, study finds
Digital technologies have profoundly transformed how adolescents acquire information and interact with each other outside school. Numerous preteens and teenagers worldwide access social media platforms daily to read posts, ...
Phys.org / New quantum encryption method prevents ciphertext from being cloned
Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the information is locked inside a math problem that would take a modern computer thousands of years ...
Medical Xpress / Rare bone disease often goes untreated while patients quietly live with chronic pain
Teeth and bones are among the hardest structures in the human body, but certain inherited conditions can rob them of that strength. One of them is hypophosphatasia (HPP), a rare, lifelong genetic bone disorder that disrupts ...
Phys.org / 3D DNA mapping in rare immune cells reveals new genes linked with autoimmune disease risk
Our DNA is often pictured as a simple spiral, like a piece of rope held taut. But inside cells, it folds into a complex three-dimensional structure, with 2 meters (6.6 feet) of DNA scrunched like a headphone wire in a pocket. ...
Phys.org / Two materials, one photonic chip: Unlocking a new way to generate light frequencies
Modern photonic chips can pack sophisticated optical functions onto devices smaller than a fingernail. They are increasingly used to generate, manipulate and measure light for applications ranging from communications to sensing. ...
Phys.org / Quantum fluid reveals hidden states that can be switched with a magnetic field
Bose-Einstein condensates (BECs) are often described as a "fifth state of matter": a quantum state in which many particles lose their individual identities and behave as one collective object. For more than 60 years, researchers ...
Phys.org / Decades-old theory for how insect societies evolve challenged
For more than 60 years, evolutionary biologists have debated whether a unique genetic system found in ants, bees and wasps helps explain one of nature's most remarkable innovations: eusociality, a form of social organization ...
