Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that cosmologists search for -- and moreover, they...
A species of tropical butterfly with unusually expanded brain structures display a fascinating mosaic pattern of neural expansion linked to a cognitive innovation.
The new mammal lived in Colorado 70 to 75 million years ago -- a time when a vast inland sea covered large portions of the state, and animals like sharks, turtles and giant crocodiles abounded.
Researchers created MobiPrint, a mobile 3D printer that can automatically measure a room and print objects onto the floor. The team's graphic interface lets users design objects in a space that the robot has mapped out. The prototype,...
For Halloween, the European Southern Observatory (ESO) reveals a spooktacular image of a dark nebula that creates the illusion of a wolf-like silhouette against a colourful cosmic backdrop. Fittingly nicknamed the Dark Wolf Nebula, it...
Researchers have developed a model to calculate how quickly or slowly an organism should ideally learn in its surroundings. An organism's ideal learning rate depends on the pace of environmental change and its life cycle, they say.
Understanding animal emotions has been a long-running question at the forefront of welfare studies, but a new study may hold the key to decoding the chatter. The answer involves two baby chickens and a mirror.
Using a few zaps of electricity to the skin, researchers can stop bacterial infections without using any drugs. For the first time, researchers designed a skin patch that uses imperceptible electric currents to control microbes.
Researchers who work with bacteriophages -- viruses that eat bacteria -- had a pleasant and potentially very important surprise after treating samples to view under an electron microscope: they had joined together into three-dimensional...
A woman who pleaded guilty to dressing as a clown and in 1990 murdering the wife of a man she later married has been released from a Florida prison. Sheila Keen-Warren was released Saturday from a prison near Tallahassee. She pleaded...
Paleobiologists have found that the sinuses of ocean dwelling relatives of modern-day crocodiles prevented them from evolving into deep divers like whales and dolphins.
A team of scientists has developed grain-sized soft robots that can be controlled using magnetic fields for targeted drug delivery, paving the way to possible improved therapies in future.
Biomedical engineers have invented a 3D printing system, or bioprinter, capable of fabricating structures that closely mimic the diverse tissues in the human body, from soft brain tissue to harder materials like cartilage and bone.
A viral video has left people scratching their heads after an optical illusion made it look as though a ballet dancer was spinning in two different directions.
CIUDAD DE MÉXICO (AP) — Cuando se acercan los festejos del Día de Muertos, a la mexicana Meztli Lizaola le resulta inevitable no acordarse de su entrañable mascota y amigo Taco, un chihuahua de pelaje marrón claro y de enternecedora...
Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing...
For the first time since 1938, children in Des Moines, Iowa, will go trick-or-treating on Halloween. Going door-to-door for candy on All Hallows’ Eve has long been commonplace throughout the country, but not in Des Moines. In Iowa’s...
Cultured meat is grown from animal muscle cells, and animal serum is required to promote the growth of these cells. However, the use of serum poses significant challenges because of its high cost and associated ethical concerns. Now,...
Researchers have developed a miniature soft lithium-ion battery that could be used as a defibrillator to control heart rhythm during surgery. The flexible lithium-ion battery is constructed by assembling biocompatible hydrogel droplets....
A surprising discovery about the black hole V404 Cygnus is expanding our understanding of black holes, the objects they can host, and the way they form.
Researchers give robots a sense of touch by 'listening' to vibrations, allowing them to identify materials, understand shapes and recognize objects just like human hands. The ability to interpret the world through acoustic vibrations...
A new PET scan reliably detects benign tumors in the pancreas, according to new research. Current scans often fail to detect these insulinomas, even though they cause symptoms due to low blood sugar levels. Once the tumor is found,...
New research shows that a large, ubiquitous mobile genetic element changes the antagonistic weaponry of Bacteroides fragilis, a common bacterium of the human gut.
Twenty-two new species of gall wasps have been identified and named, thanks to new research. The study nearly doubles the number of known species in this genus of wasps.
A new study shows the remarkable adaptability of the critically endangered Cat Ba langurs. Despite low genetic diversity, the langurs have retained key genetic traits that help them survive in their isolated environment on Cat Ba Island...
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, palaeontologists and biologists is using robots to study how the ancestors of modern land animals...
During the Day of the Dead celebrations that take place in late October and early November, Latin Americans honor their departed loved ones by setting up altars adorned with food, flowers and photographs. But what about carving the...
Researchers have pored over more than two decades' worth of data from NASA's Chandra X-Ray Observatory to show there's new knotty science to discover around black holes.
Tourists eager to fulfill the fabled promise to return to the Eternal City are being forced to toss coins over a plastic barrier and into a small makeshift pool in front of Rome’s Trevi Fountain while the iconic attraction is being...
A groundbreaking, nine-year study has revealed that elephants approaching small-scale farms in Kenya avoid beehive fences housing live honey bees up to 86% of the time during peak crop seasons, helping to reduce human-elephant conflict...
