Supercomputer turns back cosmic clock
Astronomers have tested a method for reconstructing the state of the early universe by applying it to 4000 simulated universes using the ATERUI II supercomputer at the National Astronomical Observatory of Japan (NAOJ). They found that together with n.....»»
How climate change is messing up the ocean"s biological clock, with unknown long-term consequences
Every year in the mid-latitudes of the planet, a peculiar phenomenon known as the phytoplankton spring bloom occurs. Visible from space, spectacular large and ephemeral filament-like shades of green and blue are shaped by the ocean currents......»»
The best MagSafe stands for iPhone and StandBy
One of my favorite features in iOS 17 is StandBy, which turns your iPhone into a smart display when it’s in landscape orientation and charging. One of the best ways to take full advantage of StandBy is with an upright wireless charger. Head bel.....»»
Research finds geochemical landscape drives musk oxen reproductive success
Researchers have studied Greenland musk oxen that have been followed for 25 years to see how their feeding habits affect their reproductive success. And it turns out that when they go to areas with more copper and selenium in the ground, they have mo.....»»

Step aside, internal tides: Supercomputer modeling improves satellite altimetry precision
Waves don't take place just on the ocean's surface. Underneath the crests and troughs that we can see from above are internal tides, which form when tidal flows collide with seamounts, continental slopes, and ridges on the seafloor......»»
Cosmic dust could have helped get life going on Earth
Life on our planet appeared early in Earth's history. Surprisingly early, since in its early youth our planet didn't have much of the chemical ingredients necessary for life to evolve. Since prebiotic chemicals such as sugars and amino acids are know.....»»
Predatory fish use rapid color changes to coordinate attacks, scientists discover
Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study reported in the journal Current.....»»
America returns spaceship to the Moon, a private sector first
For the first time since the Apollo era, an American spaceship has landed on the Moon: an uncrewed commercial robot, funded by NASA to pave the way for US astronauts to return to Earth's cosmic neighbor later this decade......»»
LHAASO discovers giant ultra-high-energy gamma-ray bubble, identifying the first super PeVatron
The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin of cosmic rays with energy higher than 10 Peta-Elec.....»»
Stop using rice to save your wet phone, Apple warns. What to do instead.
Stop putting wet phones in rice, Apple warns. Here’s why. As it turns out, the decades-old method of saving one's wet phone in rice isn't a good idea, according to Apple. A recent support document states that this hack actually makes things w.....»»
Quantum dark states lead to an advantage in noise reduction
While atomic clocks are already the most precise timekeeping devices in the universe, physicists are working hard to improve their accuracy even further. One way is by leveraging spin-squeezed states in clock atoms......»»
Astronomers are figuring out what causes incredibly bright flashes in space
Some of the oddest cosmic phenomena are short but powerful flashes called fast radio bursts. Now astronomers have observed one before and after it occurred,.....»»
