Silky shark observed with regrown fin after extensive injury
A marine biologist at the University of Miami's Rosenstiel School of Marine, Atmospheric, and Earth Science, has documented a case of a silky shark with a regenerated dorsal fin, after much of it was lost due to maiming by an unknown person. In her p.....»»
Oceans without sharks would be far less healthy, says new research
There are more than 500 species of sharks in the world's oceans, from the 7-inch dwarf lantern shark to whale sharks that can grow to over 35 feet long. They're found from polar waters to the equator, at the water's surface and miles deep, in the ope.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Great white sharks secretly roam through Bahamas
It's incredibly rare to spot a great white shark in the waters around the Bahamas, but a new study published in the journal Frontiers in Marine Science shows they visit the area more often than people realize......»»
Big sharks equal big impact, but there"s a big problem: Those most affected by fishing are most needed for ocean health
Shark conservation must go beyond simply protecting shark populations—it must prioritize protecting the ecological roles of sharks, according to new research published in Science......»»
New evidence of Neolithic occupations in the Aragonese site of Huerto Raso
Researchers from the UAB and the University of Zaragoza who have carried out the first extensive excavation campaign of the Huerto Raso site (Huesca) have made new discoveries that reinforce the hypothesis of its occupation during the ancient Neolith.....»»
Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»
Hyundai recalls about 50,000 vehicles over electrical wiring faults linked to airbag failures
Hyundai is recalling its 2024 Santa Fe gasoline and hybrid models in Canada and the U.S. because of electrical wiring faults that could cause airbags to deploy incorrectly or not at all, increasing the risk of injury in a crash......»»
How Kepler’s 400-year-old sunspot sketches helped solve a modern mystery
A sharp decline in sunspot activity in the 17th century has long puzzled astronomers. Enlarge / A naked-eye sunspot group on May 11, 2024. There are typically 40,000 to 50,000 sunspots observed in ~11-year solar cycles. (credit:.....»»
Substack blames iCloud Private Relay outage for big drop in newsletter open rates
Last week, Apple’s iCloud Private Relay feature experienced a days-long outage. Today, that outage is being blamed by Substack for a troubling trend that its writers observed: a substantial drop in open rates for newsletters sent during the outage......»»
Researchers create a cell atlas of the regenerating liver
The liver has a remarkable ability to regenerate. This property is crucial for maintaining organ function and recovery after injury or surgery. Scientists from the University of Leipzig Medical Center, the Max Planck Institute for Evolutionary Anthro.....»»
Injury dressings in first-aid kits reveal shark species
Scientists have revealed that injury dressings found in first-aid kits can reliably be used to identify shark species involved in bite incidents by deploying medical gauze to gather DNA samples from aquatic equipment, such as surfboards......»»
Ensuring quality in tropical vegetables: Addressing chilling injury through antioxidant systems
A research team has found that optimal storage temperatures are crucial for preserving vegetables' quality, with tropical plants particularly susceptible to low temperatures, leading to a "chilling injury" (CI) condition......»»
New data-driven map reveals extensive peatlands in Amazon Basin
A consortium of researchers led by the University of St Andrews, Scotland, and Charles University, Prague have developed a new data-driven map which predicts substantially more peatland area in the Amazon basin than previously estimated. The high-res.....»»
Dark matter seen through forest: Study examines matter distribution and supports unknown influence or new particle
The dense peaks in the wavelength distribution graph observed in a Lyman-Alpha forest indeed resemble many small trees. Each of those peaks represents a sudden drop in "light" at a specific and narrow wavelength, effectively mapping the matter that l.....»»
Two shark species documented in Puget Sound for first time
Oregon State University researchers have made the first scientific confirmation in Puget Sound of two distinct shark species, one of them critically endangered......»»
Confined water gets electric: Study reveals dielectric response of water in nanopores
When water gets inside nanopores with sizes below 10 nanometers, new physics emerge: new phases of ice were observed and ultrafast proton transport was measured. Confined water also plays a role in biology, where aquaporins cross cellular membranes t.....»»
James Webb takes rare direct image of a nearby super-Jupiter
The James Webb Space Telescope has directly imaged a gas giant beyond our solar system, and it's one of the coldest exoplanets observed so far......»»
BMW recalls almost 300,000 vehicles over rear cargo rail failures
BMW is recalling 291,112 vehicles due to rear cargo rails detaching in the event of a crash, increasing the risk of serious injury. Following a crash involving a 2022 BMW X3, BMW North America and BMW AG were legally served. An investigation led to t.....»»
