Phys.org / Tomb more than 1,000 years old found in Panama
Archaeologists have discovered a tomb more than a thousand years old in Panama containing human remains alongside gold and ceramic artifacts, the lead researcher told AFP on Friday.
Phys.org / Water is bed bugs' kryptonite: The parasites avoid wet surfaces at all costs
Humans tend to fear bed bugs, and rightly so. The bloodsuckers are tough to get rid of once they've entered a home. But new research has, for the first time, identified one thing the bugs seem to fear—water and wet surfaces.
Phys.org / Cosmologists collaborate to sharpen measurements of the Hubble constant
Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...
Medical Xpress / A silent signaling network deep in the gut protects against inflammatory intestinal disorders, scientists find
Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are listening and signaling. When ...
Tech Xplore / AI model edits can leak sensitive data via update 'fingerprints'
Artificial intelligence (AI) systems are now widely used by millions of people worldwide, as tools to source information or tackle specific tasks more rapidly and efficiently. Today, some of the most used are large language ...
Phys.org / The greatest risk of AI in higher education isn't cheating—it's the erosion of learning itself
Public debate about artificial intelligence in higher education has largely orbited a familiar worry: cheating. Will students use chatbots to write essays? Can instructors tell? Should universities ban the tech? Embrace it?
Phys.org / Engineered nanoparticles could deliver better targeted cancer treatment to lymph nodes
Scientists at McGill University and the Rosalind and Morris Goodman Cancer Institute have developed a new way to deliver cancer immunotherapy that caused fewer side effects compared to standard treatment in a preclinical ...
Phys.org / Metamaterial image sensor keeps colors clear even under oblique light
Smartphone cameras are becoming smaller, yet photos are becoming sharper. Korean researchers have elevated the limits of next-generation smartphone cameras by developing a new image sensor technology that can accurately represent ...
Medical Xpress / Oxytocin reverses anxiety-like behavior after three months of isolation in mice
Periods of prolonged social isolation have long been associated with difficult emotions and, in some cases, with the emergence of psychiatric symptoms, such as depression, anxiety, and difficulties connecting with others. ...
Medical Xpress / The postpartum experience: Recognizing complications
Postpartum experiences are as unique as the pregnancies that come before them. Because of this, it can be difficult to recognize what's normal and what could be a complication—even if you've given birth before.
Phys.org / Occupy Mars? Or the moon? Get a reality check on Elon Musk's plans
It's an age-old debate in space circles: Should humanity's first city on another world be built on the moon, or on Mars? As recently as last year, SpaceX founder Elon Musk saw missions to the moon as a "distraction." In a ...
Phys.org / Cosmic curveball: Distant system challenges planet-formation theory
An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a characteristic pattern in planetary ...
