New Laser Technique Measures Distance Between Faraway Labs To A Fraction Of Hair’s Width
A new application of laser technology known as two-way dual-comb ranging (TWDCR) has demonstrated with unprecedented precision in measuring the distance between instruments more than 100 kilometers (62 miles) apart. Improvements in long-distance ranging could help satellites fly better in formation and enhance the accuracy of scientific instruments for gravitational wave detection and very-long-baseline astronomical […]
First Infrared Flare-Up Detected From The Milky Way’s Supermassive Black Hole
Sagittarius A* is the supermassive black hole at the center of the Milky Way. As supermassive black holes go, it is fairly quiet. It’s not creating any galaxy-wide tantrums that should worry us. It does flare up though, and studying these flares across wavelengths has been very important to create models about the extreme environments […]
Study Links Frequent AI Use With Lower Critical Thinking Abilities
A new study investigating artificial intelligence (AI) and “cognitive offloading” by humans has found a negative correlation between frequent AI use and critical thinking abilities. Advertisement Large language models have become more freely available these days, whether it’s OpenAI’s ChatGPT or Google’s AI summaries, providing (often not entirely accurate) answers at potentially huge costs to […]
Rats Hiding From Scary “Robogator” Reveal How The Brain Creates A “Worry Map”
Anxiety can act as a great motivator to avoid potentially uncomfortable interactions, and it seems that even rats may fall victim to it. A new study involving rats being let loose in a maze populated by food-guarding robots has revealed how their brains behaved when anticipating future threats, changing their behavior so that they could […]
NASA Marsquake Data May Show Mars Has A Solid Inner Core, Like Earth
A new preprint study looking at data from NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) Lander has claimed to find evidence that Mars has a solid inner core, just like the Earth. Advertisement By looking at the seismic vibrations from beneath the surface, scientists can put together a picture of the […]
A Prehistoric Forest Has Hidden In The Greater Yellowstone Ecosystem For 6,000 Years
Thawing ice has unveiled remains of a long-lost forest in the Greater Yellowstone Ecosystem, indicating the profound changes that have influenced the area – and perhaps what might lie ahead. Scientists at Montana State University (MSU) studied the remains of a mature whitebark pine forest that formed nearly 6,000 years ago on the Beartooth Plateau […]
La Niña Has Finally Returned To The Pacific With A Weird And Weak Episode
La Niña reared its head in the tropical Pacific in December 2024 and it’s likely to linger for a few more months. What does that mean? In short, colossal climatic forces are set to drive lower average temperatures, as well as noticeable changes to rainfall. Advertisement The NOAA Climate Prediction Center recently announced the emergence […]
People Who’ve Had COVID Could Be Almost 8 Times As Likely To Develop ME/CFS
COVID-19 appears to be associated with a substantial rise in the number of ME/CFS cases, according to a new study. Using data from a long COVID research initiative run by the US National Institutes of Health (NIH), the scientists calculated that the incidence of ME/CFS is now 15 times higher than pre-pandemic levels, and found […]
A Giant Aquifer Discovered Beneath Oregon Could Reshape Future Volcanic Eruptions
An enormous body of water has been found in volcanic rocks below the peak of the Oregon Cascade Range. The volume is so large, the push to use it to address regional water shortages is likely to come quickly, but the solution is not that easy. Meanwhile the proximity to slumbering volcanoes could have implications […]
White Dwarf Is Refusing To Be Eaten By Supermassive Black Hole
Supermassive black holes are not picky eaters. They placidly sit at the center of galaxies, but if material gets too close, they’ll voraciously gorge on it. Stars have been disrupted and eaten too when they got too close. Now, researchers report that they have caught a supermassive black hole in the act of eating a […]
Huge Ancient Inca Underground Labyrinth Discovered Beneath Cusco, Starting At Sun Temple
After centuries of rumor and speculation, archaeologists have finally confirmed the existence of a colossal underground tunnel system beneath the Peruvian city of Cusco. Built by the ancient Inca, the labyrinth – or Chincana – radiates outwards from the Temple of the Sun, extending for more than a mile towards a fortress on the edge […]
In 1863, Samuel Butler Predicted Predicted AI Would Rise – And Rule Over Humanity
Nearly 162 years ago, a visionary predicted the evolution of machines and the rise of artificial intelligence (AI) with unnerving accuracy. He boldly foresaw a future where humanity’s mechanical creations might even gain consciousness and supplant us as the dominant species on Earth. Advertisement His name was Samuel Butler, a British-born writer (not to mention […]
Stone Age Artisans Chose Their Materials For A Reason. A New Study Is Figuring Out Why
The human Stone Age was, undeniably, the first step on a journey towards the species total technological dominance – but it didn’t have to be. After all, pick a rock that’s too soft, or too wonky, and our ancestors may never have made it past “ape with aspirations”. So how did they manage to get […]
“Mountains” On Neutron Stars Could Be Detected With Gravitational Waves
Neutron stars are among the densest objects in the universe. Their crust is far stronger than any material on Earth and a spoonful of this matter is heavier than a mountain. Talking about mountains, if they exist on neutron stars, some have hypothesized that they might be just a few millimeters tall. New work suggests […]
Women Seeking Abortions More Likely To Be Using “Natural” Birth Control Than 5 Years Ago
New data from England and Wales has identified an increase in women seeking abortions after using “natural” birth control methods – things like menstrual cycle tracking, and systems that use body temperature fluctuations to predict fertility. These methods are known to be less effective than other options like hormonal contraceptives and condoms, so there was […]
Over One-Third Of Supermassive Black Holes Are Hiding – Maybe Even More
At the center of almost every galaxy, there is a supermassive black hole. Well, astronomers think it’s every galaxy, but it is a difficult claim to confirm. Not because there might be many exceptions – the difficulty lies in the fact that many black holes are so well hidden that we wouldn’t know they are […]
Australia’s Most Deadly Spider Is Now Three Species Instead Of One
Australia might be home to a large proportion of the world’s deadliest animals but it’s about to have three more. The iconic Sydney funnel-web spider, with one of the world’s deadliest bites, has been discovered to be three species instead of one, each with a separate geography to match. Considered the spider with the most […]
“Supergiant” Sea Bug Named After Darth Vader Is 32 Centimeters Long And Weighs A Kilo
Scientists working at a crustacean laboratory in Singapore have discovered a new-to-science species of “supergiant” isopod, and it’s an absolute wedge. Known as bọ biển or “sea bugs” in Vietnam, its angular noggin has inspired an out-of-this-world species name: Bathynomus vaderi, after everyone’s favorite absent father figure, Darth Vader. B. vaderi is part of the […]
