Phys.org / Corrected Pantheon+ analysis of supernovae challenges accelerating universe claim
Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating ...
Phys.org / Poo emoji, earthworm castings and pasta all obey the same coiling theory, physicists find
Ask a child to draw some poo, and the shape will invariably be the same: a coil, broad at the base and pointy at the top, similar to a spiral swirl of soft-serve ice cream. In fact, the often-used poo emoji has this exact ...
Phys.org / California has lost more than half of its coastal sand dunes, first-ever assessment reveals
A study conducted by UC Santa Barbara researchers and collaborators has found that California has lost more than half of its coastal dune systems. The researchers' assessment—the first of its kind for the California coast—estimates ...
Tech Xplore / Top Indian tech supplier reports 'cybersecurity incident'
A top Indian maker of iPhone parts has confirmed it was hit by a "cybersecurity incident," with media reports alleging that Apple supplier specifications had been leaked.
Phys.org / Leaf-based fluorescence test speeds search for plant gene-editing targets
Gene editing of plant DNA has the potential to produce crops with increased performance and resilience, but it can take a long time to achieve these gains. To shorten this process, scientists often use screening tools to ...
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.
Phys.org / Mosquito-borne viruses avoid killing hosts by limiting protein output, study reveals
The increase in mosquito-borne virus infections is a growing public health concern. Diseases traditionally confined to tropical or subtropical regions, like dengue or West Nile virus, are expanding their geographic scope. ...
Phys.org / Women negotiate as effectively as men—but leave people happier
Men and women achieve similar economic outcomes in negotiations, but female negotiators foster stronger interpersonal relationships, which lead in turn to greater satisfaction with the result and a greater desire to negotiate ...
Medical Xpress / Coordinated brainstem slow waves may determine when it's time for REM sleep
Sleep is one of the most widely studied states of consciousness, known to play a role in physical recovery, the processing of memories and the regulation of immune functions. During sleep, the brain transitions between light ...
Phys.org / Nanotube-based thermoelectrics open a new pathway to waste-heat energy conversion
Whenever someone asks ChatGPT a question, heat is generated somewhere in the server room—a data center. When an electric vehicle battery generates heat during operation, the heat must be managed continuously. Manufacturing ...
Tech Xplore / Trump signs executive orders to boost US quantum computing
President Donald Trump signed two executive orders Monday aimed at accelerating the development of quantum computing, a cutting-edge technology that could potentially outpace today's supercomputers.
