Artificial intelligence can now predict whether someone will develop dementia within two years, a new study claims. Researchers hope the technology will cut down on false diagnoses and help doctors catch the condition earlier. Researchers from the University of Exeter in the UK took data from more than 15,000 memory …

A NASA spacecraft became the first to “touch the sun,” scientists announced Tuesday — a long-awaited milestone and a potential giant leap in understanding the sun’s influence on the solar system. The Parker Solar Probe successfully flew through the sun’s corona, or upper atmosphere, in April to sample particles and …

A brand-new space telescope will soon reveal a hidden vision of the cosmos, potentially transforming our understanding of black holes, supernovas and even the nature of the universe itself. No, not that one. Much attention is being devoted this month to the James Webb Space Telescope, from NASA and the …

The fossils obtained from across the globe have introduced us to countless types of creatures that once lived on the planet—from the giant birds of Antarctica to the largest dinosaurs of the Americas. Whenever paleontologists dig out such remarkable well-preserved fossils of these ancient creatures, they open new possibilities for …

NASA early Tuesday postponed a spacewalk outside the International Space Station by two of its astronauts after receiving a “debris notification” for the orbital outpost. Astronauts Thomas Marshburn and Kayla Barron had been due to head outside the space laboratory later Tuesday on a six-and-a-half-hour spacewalk to replace a faulty …

Poor sleep in the over 50s is linked to more negative perceptions of ageing, which in turn can impact physical, mental, and cognitive health, new research has revealed. A study led by the University of Exeter and found that people who rated their sleep the worst also felt older, and …

A US Geological Survey research geophysicist named Tom Parsons says that San Francisco is sinking into the Earth. NBC Bay Area reports that Parsons examined every single building in the Bay Area, using satellite images captured by European Space Agency’s Sentinel 1 satellite. Most of the settling appears to be …

Bedtime for adolescents is hardly ever fun. According to a new study, however, moms and dads apparently have the right idea when they make sure their kids are in bed at a reasonable hour. Scientists from Boston’s Children’s Hospital report inadequate sleep can be absolutely devastating for the developing pre-teen …

An object lurking in the outer region of our solar system may well be the elusive Planet 9, a leading British astronomer has suggested after digging through the telescope archives of 250,000 point sources. Possible evidence of a mysterious planet up to 10 times bigger than Earth, with a distant …

The phenomena named by the scientists “space weather” can affect Earth in a variety of ways: from creating fascinating light shows like auroral displays, to actually causing damage to satellite infrastructure. Earth can brace itself for solar storms “cannibalising” one another to hit the planet in the upcoming four years, …

A new species of dinosaur has been discovered on the Isle of Wight off the coast of England. With its long bulbous nose, Brighstoneus simmondsi was around eight metres long and weighed about 900kg. The name Brighstoneus comes from the village of Brighstone, near the site where the remains were …

NASA on Tuesday delayed putting astronauts back on the moon until 2025 at the earliest, missing the deadline set by the Trump administration. The space agency had been aiming for 2024 for the first moon landing by astronauts in a half-century. In announcing the delay, NASA Administrator Bill Nelson said …

A study conducted by a British research team has concluded that a regular bedtime between 10 p.m. and 11 p.m. is linked to better heart health and lower risks of heart disease. A total of 88,000 volunteers were studied during the research where each person wore a tracking bracelet that …

NASA and SpaceX have delayed a mission sending four astronauts to the International Space Station to avoid “a large storm system,” the agency said Saturday. The astronauts of “Crew-3” were due to launch aboard a Crew Dragon spacecraft named “Endurance” fixed atop a Falcon 9 rocket from the Kennedy Space …

Imagine a scorpion! What usually comes to mind is a reasonably small, finger-length, venomous creature who primarily inhabits the land. But imagine diving into a sea and coming face-to-face with a meter-long scorpion! Scientists from the Nanjing Institute of Geology and Palaeontology recently unearthed a fossil of a scorpion that …

Scientists in the US used a camera connected to a brain implant to help a blind person see again, NPR reported. The former teacher who had been blind for 16 years had the device implanted in her brain with no disruptions to brain activity or other health complications, according to …

Researchers in the Netherlands are developing laser technology to enable “virtually painless” injections without needles in what they call a breakthrough that will ease fear and lower the threshold for vaccinations. The “Bubble Gun” uses a laser to push tiny droplets through the outer layer of the skin, said David …

German Benjamin List and Scottish-born David MacMillan won the 2021 Nobel Prize in Chemistry for their development of asymmetric organocatalysis, a “new and ingenious tool for molecule building”. “Organic catalysts can be used to drive multitudes of chemical reactions,” the Royal Swedish Academy of Sciences said in a statement. “Using …

The 2021 Nobel Prize in physics has been awarded to a trio of scientists whose work laid the foundations for how we understand complex physical systems, including Earth’s climate. Syukuro Manabe, of Princeton University in New Jersey, and Klaus Hasselmann, formerly of the Max Planck Institute for Meteorology in Hamburg, …

Two scientists won the Nobel Prize in medicine on Monday for their discoveries into how the human body perceives temperature and touch, revelations that could lead to new ways of treating pain or even heart disease. Americans David Julius and Ardem Patapoutian identified receptors in the skin that respond to …
