Tech Xplore / Sheepdogs reveal a better way to guide robot swarms
Sheepdogs, bred to control large groups of sheep in open fields, have demonstrated their skills in competitions dating back to the 1870s. In these contests, a handler directs a trained dog with whistle signals to guide a ...
Medical Xpress / MRI study finds Down syndrome brain lesions can shrink over time
What has long been interpreted as permanent and irreversible vascular damage may not be exclusively so. In people with Down syndrome—one of the most robust populations for studying Alzheimer's disease due to the near-universal ...
Phys.org / Rapid melting of Antarctic sea ice is largely driven by ocean warming, research reveals
Sea ice around Antarctica expanded for several decades until a dramatic decline in 2015. The reasons behind this are revealed by research led by the University of Gothenburg, which is published in Nature Climate Change.
Phys.org / Potential Strait of Hormuz blockade could disrupt global supply chains, study finds
A prolonged closure of the Strait of Hormuz, one of the world's most important oil shipping routes, could severely disrupt global supply chains and destabilize energy markets, potentially leading to far-reaching economic ...
Phys.org / How humans took over the planet: The role of cultural evolution
Humans really do rule the world. We took over fast and far, more than any other wild vertebrates. We inhabit nearly every corner of the world, and can thrive in deserts, tropical rainforests and even extremely cold climates. ...
Phys.org / Quantum dots generate entangled photon pairs on demand
For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment surrounding a single quantum ...
Medical Xpress / Parthanatos pathway behind neuron loss in multiple sclerosis identified
Multiple sclerosis (MS) is a chronic, often debilitating autoimmune disease that affects the central nervous system (CNS). This disease causes the immune system to mistakenly attack the protective sheath surrounding nerve ...
Phys.org / Protein sequencing advance offers new insights into life's foundations
Proteins, one of the smallest building blocks of life on Earth, hold promise for answering some of biology's biggest questions. Consisting of amino acids strung together into peptide chains, these molecules perform much of ...
Medical Xpress / Usage of psychedelic psilocybin rises after state decriminalization, new study finds
Psilocybin is a naturally occurring psychedelic compound that is the active ingredient in certain types of mushrooms (also called magic mushrooms), long used by Indigenous communities in parts of Mexico and Central America ...
Medical Xpress / Clot buster may stop promising stroke medicine from working properly
A clotbusting drug commonly used to treat ischemic stroke interacts negatively with a promising anti-inflammatory treatment (anakinra), underscoring the need to test new stroke therapies alongside existing standard care. ...
Medical Xpress / The next leap for AI scribes provides eyes in the clinic
The introduction of vision-enabled artificial intelligence (AI) to medical scribes—the recording devices used by doctors to document meetings with patients in real-time—could increase the accuracy of patient notes and ...
Phys.org / Perovskite crystals can host qubits, challenging long-held assumptions
For the first time, researchers have demonstrated that the properties of the perovskite family of materials can be used to create so-called quantum bits. The findings, published in the journal Nature Communications, pave ...
