Scientists Uncover Secret Foraging Havens of the World’s Largest Turtles

Researchers in the US have used advanced tracking technology to uncover new migratory corridors and foraging areas for leatherback sea turtles along the US east coast, notably in the South Atlantic Bight, Mid-Atlantic Bight, and southern New England. These findings, published in Frontiers in Marine Science, highlight significant foraging grounds and have implications for the conservation of this endangered species, particularly in light of threats from fishing and offshore wind farm developments.Leatherback sea turtles,…

A Multi-Billion-Dollar Question – Researchers Are Closer to Understanding Hydrogen’s Great Challenge

Researchers at the University of Sydney have discovered that adding molybdenum to steel, combined with metal carbides, significantly improves its ability to trap hydrogen, potentially solving the issue of hydrogen embrittlement. This breakthrough, using advanced cryogenic atom probe tomography, could pave the way for large-scale hydrogen transport and storage solutions, essential for transitioning to a hydrogen economy.Solving embrittlement is a multi-billion-dollar question.Why hydrogen causes steels to become brittle…

The Untold Cancer Risk of Ultra-Processed Food

A recent study indicates a potential link between increased consumption of ultra-processed foods and a higher risk of cancers in the upper aerodigestive tract, suggesting that factors beyond obesity, such as additives in UPFs, might contribute to this risk. International study, led by the University of Bristol and the International Agency for Research on Cancer, analysed diet and lifestyle data on 450,111 adults who were followed for approximately 14 years.Eating more ultra-processed foods (UPFs) may be associated with a…

The Scent of a Female Can Trigger Early Death in Male Mice : ScienceAlert

Smelling a potential new mate could impact how long an animal lives and its ability to reproduce, according to a new study.Scientists found that simply exposing male mice to the scent of unknown females during middle to old age decreased the number of litters they could sire later in life. If these female-odor-sniffing males were allowed to mate, they were also likelier to die earlier than males who didn't smell outsider females before mating.The researchers from New Zealand and Australia say their study demonstrates…

Billionaires are building bunkers and buying islands—are they prepping for apocalypse or pioneering a new feudalism?

Zuckerberg and his wife, Priscilla Chan, are constructing a gigantic compound—known as Ko'olau

Star with a scar spotted in our galaxy

Astronomers spotted a “metal scar” on a white dwarf star found within our galaxy. After closer observation, the astronomers say the scar could be the remains of a destroyed planet that the star ate.The white dwarf, known as WD 0816-310, is a superdense dead star that is located just 63 light-years away from Earth. The star with the scar, as we’ll call it for now, has caught scientists’ attention as we originally assumed that the fragments of planets and asteroids eaten by white dwarfs would spread evenly across…

New Findings Shed “Literal Light” on a Decades-Long Mystery About How Photoreceptors Work

Johns Hopkins Medicine researchers have discovered that certain retinal photoreceptors employ two signaling pathways simultaneously for vision signal transmission, suggesting ancient evolutionary origins. This finding provides new insights into the complex functioning of the mammalian eye and marks a significant advancement in the field of neuroscience.Neuroscientists at Johns Hopkins have demonstrated that specialized cells can signal the presence of light simultaneously in two distinct waysWorking with mammalian retinal…

But craters weren’t all that was left behind; the intense pressure and temperature of such a collision also impacts the rocks and dust covering the lunar surface, known as regolith, altering its mineral…

How Ancient Carnivores Evolved To Dominate Land

Singh.Researchers from the University of Bristol and the Open University propose that the evolutionary success of the earliest large land predators was fueled by their need to improve as killers.The forerunners of mammals ruled the Earth for about 60 million years, long before the origin of the first dinosaurs. They diversified as the top predators on land between 315…

Scientists Reveal That Nearly All Older Americans Follow One of Nine Trajectories in Their Last Three Years of Life

A Rutgers Health study analyzing Medicare records revealed nine end-of-life care trajectories for older Americans, categorized into home, skilled home care, and institutional care clusters. This research aims to tailor end-of-life care interventions to individual preferences, improving care quality and reducing costs by understanding the factors influencing these care patterns. Credit: SciTechDaily.comA Rutgers Health analysis of millions of Medicare records has laid the groundwork for improving end-of-life care by…
