A large, 18-country study may turn current nutritional thinking on its head. The new research suggests that it’s not the fat in your diet that’s raising your risk of premature death, it’s too many carbohydrates — especially the refined, processed kinds of carbs — that may be the real killer. The research also found that Read more about Large diet study suggests it’s carbs, not fats, that are bad for your health[…]

Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U(VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits. Here we show that non-crystalline U(IV) generated through biologically mediated U(VI) reduction is the predominant U(IV) species in an undisturbed U roll-front ore deposit in Wyoming, Read more about Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits[…]
Researchers at the University of Waterloo have been able to capture the first composite image of a dark matter bridge that connects galaxies together. The scientists publish their work in a new paper in Monthly Notices of the Royal Astronomical Society. The composite image, which combines a number of individual images, confirms predictions that galaxies Read more about Researchers capture first ‘image’ of a dark matter web that connects galaxies[…]
Researchers have discovered that the lungs play a far more complex role in mammalian bodies than we thought, with new evidence revealing that they don’t just facilitate respiration – they also play a key role in blood production. In experiments involving mice, the team found that they produce more than 10 million platelets (tiny blood Read more about An Unexpected New Lung Function Has Been Found – They Make Blood[…]
Imagine a liquid that could move on its own. No need for human effort or the pull of gravity. You could put it in a container flat on a table, not touch it in any way, and it would still flow. Brandeis researchers report in a new article in Science that they have taken the Read more about Self flowing liquids[…]
The human brain reaches its adult volume by age 10, but the neurons that make it up continue to change for years after that. The connections between neighboring neurons get pruned back, as new links emerge between more widely separated areas of the brain. Eventually this reshaping slows, a sign that the brain is maturing. Read more about Your brain doesn’t stop developing[…]
Fillings could be consigned to history after scientists discovered that a drug already trialled in Alzheimer’s patients can encourage tooth regrowth and repair cavities. Researchers at King’s College London found that the drug Tideglusib stimulates the stem cells contained in the pulp of teeth so that they generate new dentine – the mineralised material under Read more about End of fillings in sight as scientists find Alzheimer’s drug makes teeth grow back […]
Today, the University of California at Berkeley has deleted 20,000 college lectures from its YouTube channel. Berkeley removed the videos because of a lawsuit brought by two students from another university under the Americans with Disabilities Act. We copied all 20,000 and are making them permanently available for free via LBRY. This makes the videos Read more about 20,000 Worldclass University Lectures Made Illegal, So We Irrevocably Mirrored Them – LBRY[…]
By using lasers to manipulate a superfluid gas known as a Bose-Einstein condensate, the team was able to coax the condensate into a quantum phase of matter that has a rigid structure—like a solid—and can flow without viscosity—a key characteristic of a superfluid. Studies into this apparently contradictory phase of matter could yield deeper insights Read more about Researchers create new form of matter—supersolid is crystalline and superfluid at the same time[…]
A new material can absorb up to 90 times its own weight in spilled oil and then be squeezed out like a sponge and reused, raising hopes for easier clean-up of oil spill sites. But to determine whether this material could help sort out a big spill in marine waters, they needed to perform a Read more about Sponge can soak up and release spilled oil hundreds of times[…]
“It has been established that charge transport is possible in DNA, but for a useful device, one wants to be able to turn the charge transport on and off. We achieved this goal by chemically modifying DNA,” said Tao, who directs the Biodesign Center for Bioelectronics and Biosensors and is a professor in the Fulton Read more about Switched-on DNA: Sparking nano-electronic applications[…]
