Researchers identify genetic mutations for rare disorder causing cognitive declineA rare cause of hereditary cognitive decline known as CSF1R-Related Disorder (CSF1R-RD) gets its name from mutations in the CSF1R gene, discovered by Mayo Clinic. Memory loss occurs as the condition advances, while early symptoms include personality changes, anxiety, depression and loss of inhibition. Genetic testing has become more widely available, but there is no cure for the disorder. | |
Earth to capture a 'second moon' this weekend, NASA saysEarth will capture a miniature, "second moon" this week, according to NASA scientists. | |
Previously unknown Neolithic society in Morocco discovered: North Africa's role in Mediterranean prehistoryArchaeological fieldwork in Morocco has discovered the earliest previously unknown farming society from a poorly understood period of northwest African prehistory. | |
Bottled water has a huge and growing toll on human and planetary health, experts warnThe huge and growing toll bottled water is taking on human and planetary health warrants an urgent rethink of its use as 1 million bottles are bought every minute around the globe, with that figure set to rise further still amid escalating demand, warn population health experts in a commentary published in the open access journal BMJ Global Health. | |
Perseverance rover spots unusual striped rock on MarsLast week, team scientists and the internet alike were amazed when Perseverance spotted a black-and-white striped rock unlike any seen on Mars before. Is this a sign of exciting discoveries to come? | |
Multiple surgeries could contribute to cognitive decline in older peopleMultiple surgeries could lead to cognitive decline, a University of Sydney study has found, using data from the United Kingdom's Biobank to analyze half a million patients aged 40 to 69 and followed over 20 years of brain scans, cognitive tests and medical records. | |
Mysterious orca group near Chile tracked down, revealing newly discovered hunting skillsOff the coast of Chile, in waters filled with krill and anchovy by the Humboldt Current system, live an elusive and little-known population of orcas. Thanks to citizen science and years of dedicated surveillance, a team of scientists led by Dr. Ana García Cegarra of the Universidad de Antofagasta is unveiling their secrets—starting with dinner. | |
First observation of ultra-rare particle decay could uncover new physicsScientists at CERN have discovered an ultra-rare particle decay process, opening a new path to find physics beyond our understanding of how the building blocks of matter interact. | |
'Doomsday' glacier set to melt faster and swell seas as world heats up, say scientistsTidal action on the underside of the Thwaites Glacier in the Antarctic will "inexorably" accelerate melting this century, according to new research by British and American scientists. The researchers warn the faster melting could destabilize the entire West Antarctic Ice sheet, leading to its eventual collapse. | |
Low gravity in space travel found to weaken and disrupt normal rhythm in heart muscle cellsJohns Hopkins Medicine scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in space weakened the tissues and disrupted their normal rhythmic beats when compared to Earth-bound samples from the same source. | |
Enigmatic archaeological site in Madagascar may have been built by people with Zoroastrian origins, research suggestsAt the turn of the first millennium AD, an unknown group of people lived in the inland Isalo massif of southern Madagascar. Here, they built vast terraces and carved large stone chambers and small hollow rock niches. The architecture is unlike anything else found in Madagascar or the adjacent East African coast. Who built these structures, when they arrived, and why was unknown. | |
New physics needed? Experts suggest possibility of updating fundamental physics conceptsAn unexpected finding about how our universe formed is again raising the question: do we need new physics? The answer could fundamentally change what physics students are taught in classes around the world. | |
Unexpected deep-sea discovery shines light on life in the twilight zoneThe ocean's twilight zone is deep, dark, and—according to new research—iron deficient. No sunlight reaches this region 200 to 1,000 meters below the sea surface, where levels of iron, a key micronutrient, are so low that the growth of bacteria is restricted. To compensate, these bacteria produce molecules called siderophores, which help the bacteria scavenge trace amounts of iron from the surrounding seawater. | |
Archaeologists use AI to find hundreds of geoglyphs in Peru's Nazca DesertA small team of archaeologists at Yamagata University, working with a colleague from Université Paris, and a pair of AI researchers from the IBM Thomas J. Watson Research Center, used an AI model to find more geoglyphs on the floor of Peru's Nazca Desert. | |
Quantized redshift and challenges to Big Bang hypothesisA Doppler shift is defined as a change of frequency of light or sound when an object is moving toward or away from an observer. Edwin Hubble observed in 1929 that galaxies appear on average to be moving away from us (see figure above), which could indicate that the universe is expanding, an effect that became known as the Hubble Law. | |
Seal species carries 'genetic scars' after being hunted to the edge of extinction, new research revealsNorthern Elephant seals have staged a remarkable comeback after narrowly escaping extinction by hunting, but new research reveals lasting genetic effects in the present population. | |
Telescope captures the most detailed infrared map ever of our Milky WayAstronomers have published a gigantic infrared map of the Milky Way containing more than 1.5 billion objects―the most detailed one ever made. Using the European Southern Observatory's VISTA telescope, the team monitored the central regions of our galaxy over more than 13 years. At 500 terabytes of data, this is the largest observational project ever carried out with an ESO telescope. | |
Study suggests moon may have been captured from space rather than formed from collision particlesOver six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basaltic and dating to about 60 million years after the solar system formed. | |
Hubble finds that a black hole beam promotes stellar eruptionsIn a surprise finding, astronomers using the NASA/ESA Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but are apparently in a dangerous neighborhood nearby. | |
