When people replace the monster myth with ecological truth, they see sharks not as threats, but as marvels. Cultural narratives about sharks stands in the way of conservationfear drives policymyth drives management. Knowledge dissolves fear, compassion replaces misunderstanding, and empathy leads to protection. Sharks are fascinating animals with a range of personalities. They suffer from numerous misleading stereotypes and myths and instill fear in many people who so much as think about them.1 However, shark attacks on people are actually rare.2
Now, in a recent episode of "The Kardashians " her doctor told her that she has "holes" in her brain, based on recent scans, which are related to "low activity" and caused by chronic stress. Don't necessarily take it at face value. In a recent piece for The Conversation, Curtin University neurology senior research fellow Sarah Hellewell warned that there's little merit to the tech used by Kardashian's physician, and that we should take his diagnosis with a massive grain of salt.
The Earth's Surface geology layer depicts geologic units exposed at the Earth's surface in the conterminous United States, ranging in age from Quaternary glacial deposits and alluvium to Precambrian crystalline bedrock. In the U.S. West and Southeast, the map is a composite of 29 state geologic maps depicting geology at the Earth's surface. In the glaciated region of the Midwest and Northeast, the map is a composite of 21 state geologic maps depicting pre-Quaternary rocks ("bedrock"), 8 state geologic maps depicting Quaternary deposits, and 18 USGS Quaternary Atlas Series maps depicting Quaternary deposits. The Quaternary Atlas maps were used where modern state geologic maps were not available.
ESA / Webb, NASA & CSA, G. Mahler Day 7 of the 2025 Space Telescope Advent Calendar: A Warped View Through an Einstein Ring. You are seeing two galaxies here, one in front of the other. The more distant spiral galaxy appears warped and distorted due to the gravitational lensing occurring around a massive, much closer galaxy, which is part of galaxy cluster SMACSJ0028.2-7537.
Modern military aircraft reflect some of humanity's most sophisticated engineering achievements in the world. These planes combine cutting-edge technology, effective design, and top-of-the-line performance. They're built not only to fly faster and farther than ever before but also to accomplish a variety of other tasks, like gather intelligence, evade detection, and carry out specific missions. Today's incredibly built craft are a testament to true innovation, from stealth fighters that remain invisible on radar to surveillance aircraft that can track threats with precision.
For the first time in California, citizen scientists like Hernandez can join the effort to track monarch butterflies thanks to Blu+, a new generation of ultra-light tags that communicate using Bluetooth technology. Through the Project Monarch app, available for iPhone or Android, anyone with a smartphone can assist researchers in monitoring migration patterns by scanning their surroundings. If a Blu+ tagged butterfly flutters within a 100-yard range, the phone detects the signal and uploads data to a central database.
Numerous stories have been written about the growing swarm of Starlink satellites in low earth orbit (LEO) over the past few years, as astronomers grow increasingly worried about the crafts' impact on their observation equipment. Launched by Elon Musk's SpaceX, each satellite has the potential to disrupt astronomy through both radio emissions and light pollution - and as the number of satellites grows, so too does the amount of interference. Now, a new study by researchers at NASA is warning that obstructions caused by SpaceX and other private satellite companies are becoming so severe that not even the Hubble Space Telescope is safe.
Some 4,500 years ago, people dug a series of deep, wide pits in the area near Durrington Walls in southern England. They were gemometrically arranged, forming a 2-kilometer (1.2-mile) wide circle that enclosed over three square kilometers (1.16 square miles). Long mistaken for naturally occuring features, the circle of human-made shafts has now come to be understood as a colossal project that lends new dimensions to the Stonehenge landscape.
Astronomers have long sought a cosmic explanation for the Bible's Star of Bethlehem, the shining celestial object that, so the story goes, guided the wise men, or magi, from Jerusalem to greet the baby Jesus. One long-standing hypothesis held that the Star of Bethlehem was in fact a conjunction, perhaps between Jupiter and Saturn. But this holiday season, a scientist has presented a new contender: a comet.
The emerging consensus is striking-the mind does not merely interpret reality; it actively participates in shaping it. Across research on the placebo effect, athletic peak performance, and self-fulfilling prophecies, a consistent pattern appears: what we expect, believe, and even feel profoundly alters how we experience the world. Put differently, the mind is not a passive observer. It is a predictive, generative, reality-filtering system-one that continually constructs the lens through which we live our daily experiences.
Priceless rock extracted from Scotland's legendary Great Glen Fault could help answer 'fundamental questions about the history of the Earth'. Experts at the British Geological Survey say the extracted core sample - essentially rock pulled from Earth using a hollow drill - measures a total of about 5,000 feet. It has been taken from more than 2,000 feet below ground level along the Great Glen Fault, which stretches from Norway through Scotland to Ireland.
The same optic fibers that pulse with the world's Internet traffic are now listening to the pulse of the planet, picking up earthquake tremors in better detail than traditional seismic networks do. In a recent Science study, researchers used 15 kilometers of telecom fiber near Mendocino, Calif., to record the region's biggest earthquake in five yearscapturing in fine detail how the magnitude 7 rupture started, slowed and sped up, accelerating even faster than the speed of sound.
Paul shared a video with his 6.4million followers on X Thursday night, showing a mysterious bright orb hovering over Puerto Rico on December 3. A member of Paul's business team claimed to have witnessed the unidentified object flying over a local marina on the island before shooting up into space and leaving a visible streak in the sky as it disappeared, the X post stated.
The billionaire CEO of the Columbia Sportswear Company has just made anyone who believes the Earth is flat an opportunity of a lifetime. Tim Boyle, 76, announced a new competition on Tuesday, which challenged 'flat Earthers' to find the actual edge of the planet and bring back a picture of the abyss that sits beyond. Boyle, who is worth an estimated $1.6billion, said the reward for their world-changing discovery would be the control of his $3billion family business, which was founded in 1938.
If you're on the surface of Earthand I'm betting you arethere are many ways to reliably estimate the distance to some object. One we use almost subconsciously is to compare an object's apparent size with how big we know it to be. For example, you have a good feel for the size of, say, a typical human. So if you see someone looming large in your vision, you can reckon they're nearby, whereas if they appear very small, they must be much farther away.
Astronomers have found what could become the first target for a crucial test of NASA's upcoming Nancy Grace Roman Space Telescope, a soon-to-launch observatory that serves as a pathfinder mission for discovering Earthlike worlds around other stars. In a pair of new studies, an international research team has revealed two newfound objects around nearby stars: a gas-giant exoplanet orbiting the star HIP 54515 and a brown dwarf around the star HIP 71618.
China is redrawing the global science map, according to an analysis of citation data by the analytics firm Clarivate. The country is increasing research collaborations with European partners, even as it expands into emerging areas from southeast Asia to the Middle East and Africa. The United States, meanwhile, is losing its long-held lead as a research powerhouse and collaborator in world science.
Though they look still on the surface, millions of optical and radar satellite images collected from 2014-2022 reveal that the rate of each glacier's flow depends on the season and geographic location. In Arctic regions of Russia and Europe, for instance, glaciers typically reach top speeds during summer or early fall, while in Alaska, they accelerate the most during spring.
Dyer told Space.com that solar radiation on the day of the flight was within normal levels and far too low to affect the aircraft. '[Cosmic rays] can interact with modern microelectronics and change the state of a circuit,' Dyer said. 'They can cause a simple bit flip, like a 0 to 1 or 1 to 0, messing up information and making things go wrong. 'They can even induce hardware failures when they generate a current in an electronic device and burn it out.'
The book is a history of carbon dioxide's complicated and vital role in shaping life on Earth, told across many millions of years. It is only during the very last bit of that span when humans had the chance to start messing around with everything, and while we talked about that part, a lot of this first segment was spent with Drew and I asking Peter very basic questions about carbon dioxide, and him giving very interesting and detailed answers.
Using some of the world's most powerful telescopes, a team of researchers found more than 280 galaxies stretched in a line through the cosmos. These galaxies are studded throughout a vast filament of gas and dark matter, which is turning on its central axis like a giant cosmic 'rolling pin'. The researchers say that this filament, and the hundreds of galaxies inside it, is spinning at speeds over 246,000 miles per hour (396,000 km/s).
Scientists have identified a protein that may be key to proper sperm formation. Without it, male mice produced no viable sperm, they found. A team at the RIKEN Center for Biosystems Dynamics Research in Japan found that a protein called Poc5 appears critical to the development of sperm's tailthe vital part that helps them swim toward an egg in order to fertilize it.
Day 4 of the 2025 Space Telescope Advent Calendar: Star Birth in the Lobster Nebula. NASA's James Webb Space Telescope recently imaged a region where the radiation and winds from a group of superhot infant stars are blasting and sculpting dense clouds of surrounding dust.
Then the proboscis/nozzle was aligned with the outlet of the plastic tip. Finally, the proboscis and the tip were bonded with UV-curable resin. The necroprinter achieved a resolution ranging from 18 to 22 microns, which was two times smaller than the printers using the smallest commercially available metal dispensing tips. The first print tests included honeycomb structures measuring 600 microns, a microscale maple leaf, and scaffolds for cells.
It could also be the time he led an expedition in the Canadian high Arctic, battling unforgiving ice to locate a lost British vessel crushed by those same elements. Or, when diving in waters off the Florida Keys humming with history, he passed a pod of lobsters clustered in a reef that was composed entirely of 16th-century silver bars from a Spanish galleon.
The clear divergence in approaches to public research funding in the East and West is laid bare in the first Nature Index ranking for applied sciences. China dominates the ranking and other Asian countries, such as South Korea and Singapore, boast an outsized performance in the field for the scale of their overall research output. It's a different story for many Western countries, however, which have a relatively small Nature Index output in the applied sciences.
Here, using an optimized 3D suspension culture system, we have successfully advanced the in vitro culture of a stem cell-derived monkey blastoid to day 25. Morphological and histological analyses showed that these monkey embryoids underwent gastrulation and largely recapitulated key developmental events of the late gastrulation stage observed in vivo, with the appearance of a neural plate, haematopoietic system, allantois, primitive gut, primordial germ cells, yolk sac structures and progenitors of other organs, excluding trophoblast derivatives.
She imagined colleagues thinking, "Oh, that's the weird one who works on astrocytes," says Goshen, whose laboratory is at the Hebrew University of Jerusalem. A lot of people were sceptical, she says. But not any more. A rush of studies from labs in many subfields are revealing just how important these cells are in shaping our behaviour, mood and memory. Long thought of as support cells, astrocytes are emerging as key players in health and disease.
Oleg Artemyev is said to have been accused of photographing classified documents and rocket equipment at a SpaceX facility in Hawthorne, California, and then 'smuggling' that information out of the building on his phone in late November. The 54-year-old was scheduled to be part of the SpaceX Crew-12 mission, led by NASA, heading to the International Space Station (ISS) in early 2026.
Kian Sadeghi, the 25-year-old founder and CEO at Nucleus Genomics, believes every parent has a right to do just that, selecting qualities they desire - from height to weight to intelligence. He calls it "genetic optimization," and it's part of a Silicon Valley push to breed "super-babies." Sadeghi dropped out of the University of Pennsylvania and started the company in 2021, inspired by a cousin who died of a rare genetic illness.
Even before this year's Spotify Wrapped dropped, I had a hunch what mine would reveal. Lo and behold, one of my most-listened-to songs was an obscure 2004 track titled " Rusty Chevrolet " by the Irish band Shanneyganock. I heard it first thanks to my son, whose friend had been singing it on the swings at school. My son found it utterly hilarious, and it's been playing in our house nonstop ever since.
The authors have retracted this paper for the following reasons: post-publication, the results were found to be sensitive to the removal of one country, Uzbekistan, where inaccuracies were noted in the underlying economic data for the period 19951999. Furthermore, spatial auto-correlation was argued to be relevant for the uncertainty ranges. The authors corrected the data from Uzbekistan for 19951999 and controlled for data source transitions and higher-order trends as present in the Uzbekistan data.
