Ultrasmall Space Junk Can Be an Invisible Satellite Killer. Scientists Are Learning How to Track It
An ambitious U.S. government program is working to detect and track millions of tiny space junk pieces—down to the size of a sand grain—throughout low-Earth orbit and beyond.....»»
Where"s my qubit? Scientists develop technique to detect atom loss
Quiet quitting isn't just for burned out employees. Atoms carrying information inside quantum computers, known as qubits, sometimes vanish silently from their posts. This problematic phenomenon, called atom loss, corrupts data and spoils calculations.....»»
Uncovering a centaur"s tracks: Scientists examine unique asteroid-comet hybrid
Although our solar system is billions of years old, we've only recently become better acquainted with one of its more dynamic and captivating inhabitants known as (2060) Chiron......»»
Scientists provide insights into photosystem II under low-light conditions
In higher plants and green algae, photosystem II (PSII) usually combines with light harvesting complex II (LHCII) to form the PSII-LHCII supercomplex. Under low-light conditions, the PSII-LHCII supercomplexes are organized laterally into higher-order.....»»
Melting sea ice in Antarctica causes ocean storms, scientists say
The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday......»»
How bad will it get? Political scientists have a pessimism bias, study finds
The past decade has seen historic challenges for U.S. democracy and an intense focus by scholars on events that seem to signal democratic decline. But new research released Dec. 17 finds that a bias toward pessimism among U.S. political scientists of.....»»
Ice is melting, seas are rising—how scientists are tracking the changes
Will the sea rise by 20 cm or 3 meters by 2100? This is obviously an interesting question to answer. Predicting the sea level in 75 years requires precise calculations and correct models of the melting of the ice from, e.g., Greenland. To do so, rese.....»»
Scientists witness evolution in action when two lizard species meet for the first time
In South Florida, two Caribbean lizard species met for the first time. What followed provided some of the clearest evidence to date of evolution in action......»»
Spiderweb protocluster captured by Webb shows supermassive black holes can halt star formation
An international research team has used the James Webb Space Telescope (JWST) to observe massive galaxies discovered by the Subaru Telescope in a corner of the early universe known as the Spiderweb protocluster. The JWST results confirm what had been.....»»
Machine learning framework improves groundwater recharge estimates in Western Australia
A new study led by Griffith University has unveiled a machine learning-based framework to accurately estimate groundwater recharge in the Perth Basin, with a particular focus on the Gnangara groundwater system......»»
Ancient clay remedy may have potential to boost modern gut health
A team of scientists has discovered that an ancient medicinal clay known as Lemnian earth (LE) could inspire new understanding of how to support present-day gut health......»»
Climate change made Cyclone Chido stronger: Scientists
Climate change intensified Cyclone Chido as it barreled toward the Indian Ocean archipelago of Mayotte, said a preliminary study by scientists studying the link between global warming and tropical storms......»»
Building a backbone: Scientists recreate the body"s "GPS system" in the lab
Scientists at the Francis Crick Institute have generated human stem cell models which, for the first time, contain notochord—a tissue in the developing embryo that acts like a navigation system, directing cells where to build the spine and nervous.....»»
Dormant massive black hole in the early universe challenges existing models
Scientists have spotted a massive black hole in the early universe that is "napping" after stuffing itself with too much food. Like a bear gorging itself on salmon before hibernating for the winter, or a much-needed nap after Christmas dinner, this b.....»»
Thin-film tech makes nuclear clocks a 1,000 times less radioactive and more affordable
In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in the atom's nucleus, which are less affected b.....»»
Chinese astronauts perform record-breaking 9-hour spacewalk
Two Chinese astronauts have performed the longest-ever single spacewalk, from the Tiangong space station......»»
Russian space chief says country will fly on space station until 2030
"Space is an area of activity where there is never a 100 percent guaranteed result." In a wide-ranging interview with a Russian television station, the chief executive of Russia's.....»»
Leakers clash over iPhone 17 camera layout – triangular versus horizontal
Two leakers, each with enough of a track record to give them some credibility, are clashing over the iPhone 17 camera layout. The first says that the iPhone 17 Pro will adopt a horizontal layout in a module with a similar shape to the Dynamic Isla.....»»
Japanese startup"s space rocket launch fails
A space rocket built by a Japanese startup blasted off on Wednesday but was later seen spiraling downwards in the distance as the company said the launch had to be terminated......»»
Young exoplanet"s atmosphere unexpectedly differs from its birthplace
Just as some children physically resemble their parents, many scientists have long thought that developing planets should resemble the swirling disk of gas and dust that births them......»»
NASA again delays return of astronauts stranded on space station
