Mystery of 'very odd' elasmosaur finally solved: fiercely predatory marine reptile is new species
A group of fossils of elasmosaurs -- some of the most famous in North America -- have just been formally identified as belonging to a 'very odd' new genus of the sea monster, unlike any previously known. This primitive 85-million-year-old, 12 meter-long, fiercely predatory marine reptile is unlike any elasmosaur known to-date and hunted its prey from above. 05/23/2025 12:06 PM
Different phases of evolution during ice age
Cold-adapted animals started to evolve 2.6 million years ago when the permanent ice at the poles became more prevalent. There followed a time when the continental ice sheets expanded and contracted and around 700,000 years ago the cold periods doubled in length. This is when many of the current cold-adapted species, as well as extinct ones like mammoths, evolved. 05/23/2025 12:04 PM
Researchers make breakthrough in semiconductor technology set to supercharge 6G delivery
Self-driving cars which eliminate traffic jams, getting a healthcare diagnosis instantly without leaving your home, or feeling the touch of loved ones based across the continent may sound like the stuff of science fiction. But new research could make all this and more a step closer to reality thanks to a radical breakthrough in semiconductor technology. 05/22/2025 06:32 PM
New ketamine study promises extended relief for depression
For the nearly 30 percent of major depressive disorder patients who are resistant to treatment, ketamine provides some amount of normalcy, but it requires frequent treatment and can have side effects. Researchers now show in proof-of-concept experiments that it may be possible to extend ketamine's antidepressant effect from about a week to up to two months. 05/22/2025 06:32 PM
Brain drain? More like brain gain: How high-skilled emigration boosts global prosperity
As the US national debate intensifies around immigration, a new study is challenging conventional wisdom about 'brain drain'--the idea that when skilled workers emigrate from developing countries, their home economies suffer. 05/22/2025 06:31 PM
The scent of death? Worms experience altered fertility and lifespan when exposed to dead counterparts
Research reveals that for C. elegans worms, the presence of dead members of their species has profound behavioral and physiological effects, leading them to more quickly reproduce and shortening their lifespans. 05/22/2025 04:27 PM
New study reveals how competition between algae is transforming the Gulf of Maine
New research shows how rapidly proliferating turf algae are waging 'chemical warfare' to inhibit the recovery of kelp forests along Maine's warming coast. 05/22/2025 04:27 PM
Ancient DNA used to map evolution of fever-causing bacteria
Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process. 05/22/2025 04:25 PM
Why Europe's fisheries management needs a rethink
Every year, total allowable catches (TACs) and fishing quotas are set across Europe through a multi-step process -- and yet many fish stocks in EU waters remain overfished. A new analysis reveals that politically agreed-upon catch limits are not sustainable because fish stock sizes are systematically overestimated and quotas regularly exceed scientific advice. In order to promote profitable and sustainable fisheries, the researchers propose establishing an independent institution to determine ecosystem-based catch limits that management bodies must not exceed. 05/22/2025 04:25 PM
Scientists have figured out how extinct giant ground sloths got so big and where it all went wrong
Scientists have analyzed ancient DNA and compared more than 400 fossils from 17 natural history museums to figure out how and why extinct sloths got so big. 05/22/2025 04:25 PM
A new approach could fractionate crude oil using much less energy
Engineers developed a membrane that filters the components of crude oil by their molecular size, an advance that could dramatically reduce the amount of energy needed for crude oil fractionation. 05/22/2025 04:25 PM
Social connection is still underappreciated as a medically relevant health factor
New studies reveal that both the public and healthcare providers often overlook social connection as a key factor in physical health, even though loneliness rivals smoking and obesity in health risks. 05/22/2025 01:35 PM
Tapping into the World's largest gold reserves
Earth's largest gold reserves are not kept inside Fort Knox, the United States Bullion Depository. In fact, they are hidden much deeper in the ground than one would expect. More than 99.999% of Earth's stores of gold and other precious metals lie buried under 3,000 km of solid rock, locked away within the Earth's metallic core and far beyond the reaches of humankind. Now, researchers have found traces of the precious metal Ruthenium (Ru) in volcanic rocks on the islands of Hawaii that must ultimately have come from the Earth's core. 05/22/2025 01:35 PM
'Selfish' genes called introners proven to be a major source of genetic complexity
A new study proves that a type of genetic element called 'introners' are the mechanism by which many introns spread within and between species, also providing evidence of eight instances in which introners have transferred between unrelated species in a process called 'horizontal gene transfer,' the first proven examples of this phenomenon. 05/22/2025 01:35 PM
Climate change poses severe threat to bowhead whale habitat
New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent. 05/22/2025 12:55 PM
New atom-swapping method applied to complex organic structures
Chemists have developed an efficient skeletal editing method for frequently used heteroaromatic structures. The technique could serve as a means to chemically modify biologically active compounds. 05/22/2025 12:54 PM
ALMA measures evolution of monster barred spiral galaxy
Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our understanding of how barred spiral galaxies, like our own Milky Way Galaxy, grow and evolve. 05/22/2025 12:54 PM
Saturn's moon: Mysterious wobbling atmosphere like a gyroscope
The puzzling behavior of Titan's atmosphere has been revealed. The team has shown that the thick, hazy atmosphere of Saturn's largest moon doesn't spin in line with its surface, but instead wobbles like a gyroscope, shifting with the seasons. 05/22/2025 12:52 PM
How property owners can work to prevent flooding
The risk of heavy rainfall and severe flooding increases with climate change. But property owners -- regardless of size -- often underestimate their own responsibility and are unaware of what preventive measures they can take themselves. 05/22/2025 12:48 PM
Breakthrough AI model could transform how we prepare for natural disasters
From deadly floods in Europe to intensifying tropical cyclones around the world, the climate crisis has made timely and precise forecasting more essential than ever. Yet traditional forecasting methods rely on highly complex numerical models developed over decades, requiring powerful supercomputers and large teams of experts. According to its developers, Aurora offers a powerful and efficient alternative using artificial intelligence. 05/22/2025 12:48 PM
