In world first, 13-year-old has been cured of incurable brain cancerIn a historic medical breakthrough, a 13-year-old Belgian boy has been cured of incurable brain cancer.

A Simple Blood Test Could Soon Predict Your Risk of DementiaA detailed look at minute differences in the levels of specific proteins in blood has allowed researchers to identify potential early warning signs of dementia.

New research helps create new antibiotic that evades bacterial resistanceScientists at the University of Illinois Chicago and Harvard University have developed an antibiotic that could give medicine a new weapon to fight drug-resistant bacteria and the diseases they cause.

New species of pirate spiders discovered on South Atlantic islandOn a remote tropical island in the Atlantic Ocean, a pair of marooned pirates have been discovered. While they lack eyepatches and cutlasses, the two new species of pirate spider certainly live up to their nautical name, which refers to their habit of violently taking over the webs of other spiders and killing the occupants.

Can the Gaia Hypothesis Be Tested in the Lab?During the 1970s, inventor/environmentalist James Lovelock and evolutionary biologist Lynn Margulis proposed the Gaia Hypothesis. This theory posits that Earth is a single, self-regulating system where the atmosphere, hydrosphere, all life, and their inorganic surroundings work together to maintain the conditions for life on the planet. This theory was largely inspired by Lovelock’s work with … Continue reading "Can the Gaia Hypothesis Be Tested in the Lab?"

Lab study creates artificial magnetosphere to explore spontaneous excitation of chorus emissionsA dipole magnetic field, created by a ring current, is the most fundamental type of magnetic field that is found both in laboratories and in space. Planetary magnetospheres, such as Jupiter's, effectively confine plasma.

Amazon unveils largest text-to-speech model ever madeA team of artificial intelligence researchers at Amazon AGI announced the development of what they are describing as the largest text-to-speech model ever made. By largest, they mean having the most parameters and using the largest training dataset. They have published a paper on the arXiv preprint server describing how the model was developed and trained.

Polar bears unlikely to adapt to longer summersMore time stranded on land means greater risk of starvation for polar bears, a new study indicates. During three summer weeks, 20 polar bears closely observed by scientists tried different strategies to maintain energy reserves, including resting, scavenging and foraging. Yet nearly all of them lost weight rapidly: on average around 1 kilogram, or 2.2 pounds, per day. Some have speculated that polar bears might adapt to the longer ice-free seasons due to climate warming by acting like their grizzly bear relatives and either rest or eat terrestrial food. The polar bears in this study tried versions of both strategies -- with little success.

Climate Change Will Make Locust Outbreaks Harder to ControlDesert locust outbreaks will be “increasingly hard to prevent and control” in a warming climate.

Amazon Rainforest Facing Drastic Collapse From 2050, Scientists WarnThe Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world.

Why Wellness Culture Has Cozied Up to LeechesThe bloodsucking worms might conjure an era of vampiric pseudoscience, but their powerful jaws are inspiring new applications.

Ancient DNA Reveals a Tragic Genocide Hidden in Humanity's PastThe rise of farming in late Stone Age Europe was no smooth transition from hunter-gatherer lifestyles but a bloody takeover that saw nomadic populations wiped out by farmer-settlers in a few generations, a new study has found.

MIT's Albumin-based cancer vaccine shows promising results in trialsMIT's albumin-based cancer vaccine shows promise in clinical trials, yielding robust immune responses, raising hope for effective cancer treatment.

From crop to cup: A new genetic map could make your morning coffee more climate resilientA new genetic map of the arabica coffee plant, Coffea arabica, could help breeders develop to more climate-proof brews.

Regular Erections May Be Vital For Erectile FunctionCars should be taken out for a spin every now and then to keep them in tip-top working order.

Bizarre “Alien-Faced” Multi-Legged Forest Dwellers Discovered in Remote African JungleResearchers have uncovered a new genus and five new species of millipedes in remote African jungles – and say the many-legged creatures could hold important clues to whether woody vines are choking or protecting the world’s forests. University of the Sunshine Coast Professor Andy Marshall said th

This Ancient Cave Art Passed Survival Information Across 130 Human Generations in Patagonia, Study SuggestsDating to as early as 8,200 years ago, the paintings may have maintained collective memories during an extremely dry period in history

What turned Earth into a giant snowball 700 million years ago? Scientists now have an answerInspired during field work in South Australia's Flinders Ranges, geoscientists have proposed that all-time low volcanic carbon dioxide emissions triggered a 57-million-year-long global 'Sturtian' ice age.
