Phys.org / Nearly 50 years of data reveal happiness gap for single parents
Single parents are less happy than parents with a partner, according to a comprehensive analysis of global studies spanning nearly 50 years of data. With the number of solo caregivers on the rise in many countries, scientists ...
Medical Xpress / Experimental mRNA vaccine shows promise against multiple Ebola strains
Scientists from China have developed a new broad-spectrum mRNA vaccine that could provide long-term protection against the most lethal family of Ebola viruses, including the Bundibugyo strain behind the current outbreak in ...
Phys.org / Gentoo penguins cope with climate change heat waves by breeding earlier
Over the past few decades, heat waves have become more common in several parts of the world as our planet warms. That's a huge problem for many animals, as it can lead to habitat loss and push their bodies to lethal thresholds. ...
Phys.org / AI makes a major breakthrough in a math problem that had stumped experts for decades
For nearly 80 years, mathematicians have struggled to solve a classic geometry puzzle first posed by Paul Erdős in 1946: the planar unit distance problem. The question posed by the legendary Hungarian mathematician was, on ...
Tech Xplore / Smartphones may soon be able to track hidden objects using LiDAR
Modern smartphones are packed with incredible technology, from high-resolution cameras and advanced graphics chips to AI processors. In premium models, this hardware includes LiDAR (light detection and ranging), which helps ...
Science X / Hidden menstrual cycle patterns offer new way to track aging and long-term health
Scientists at SRI International in the US have developed an open-source tool designed to analyze the vast wealth of physiological data hidden within the menstrual cycle. Their long-term goal is to provide personalized health ...
Science X / A whale meets itself at last: Belugas may have crossed a cognition line to join an elite group of animals
For humans, recognizing our reflection comes naturally, and we barely give it a second thought. Called mirror self-recognition (MSR), it is widely considered a sign of self-awareness and cognitive development. In the animal ...
Science X / A 6,000-year-old necropolis in central Spain is forcing a radical rethink of who built Europe's first great tombs
Archaeologists working in Toledo, central Spain, have discovered what they believe is the oldest documented monumental necropolis in the interior of the Iberian Peninsula. This ancient site dates back to about the end of ...
Phys.org / New insights into how the human hand evolved from our ape-like ancestors
The human hand is an evolutionary marvel. While other primates rely on their hands for locomotion and basic grasping, ours can shape tools, manipulate objects, and perform detailed tasks requiring great dexterity and precision. ...
Phys.org / Climate catch-22: Cleaning up air pollution could speed key Atlantic current decline
It may sound counterintuitive, but new research suggests that cleaning up air pollution could contribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This is the ocean current system that acts ...
Phys.org / Rare seals hide in underwater bubble caves to escape tourists
The uninhabited islet of Formicula in Greece's Inner Ionian archipelago is a popular tourist draw for its clear waters, swimming spots, and marine diversity. A major attraction is the Mediterranean monk seal, one of the world's ...
Science X / How swarms of tiny light-controlled robots could revolutionize wound care
Having a swarm of microbots moving across your body may sound like the stuff of a horror movie, but it could actually be the future of targeted drug delivery and advanced wound healing. Scientists have developed a way to ...
Science X / The asteroid that wiped out the dinosaurs may have triggered a global fungal bloom
The asteroid that smacked into our planet about 66 million years ago at the Cretaceous-Paleogene (K/Pg) boundary may have been bad news for dinosaurs, but it was good news for fungi. According to new research published in ...
Phys.org / Webb discovers one of the universe's first galaxies
Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe's first stars and is one of the most chemically primitive galaxies observed ...
Medical Xpress / Ultra-processed foods tied to nearly fourfold asthma risk in children
Children who get more than 30% of their daily energy from ultra-processed foods (UPFs), such as soda drinks, packaged snacks, and sweetened breakfast cereals, have a nearly fourfold risk of developing asthma in their early ...
