45,000-year-old human genomes reveal extent of Neanderthal interbreeding

Two new genetic studies have shed light on just how often our ancestors got frisky with Neanderthals. Scientists analyzed the genomes of 45,000-year-old human remains found in caves in Czechia and Bulgaria, including the oldest known genome of a modern… Continue reading 45,000-year-old human genomes reveal extent of Neanderthal interbreeding

AI identifies three subtypes of multiple sclerosis in MRI brain scans

Scientists may have identified three new subtypes of multiple sclerosis (MS). A team trained artificial intelligence algorithms on a large dataset of MRI scans of the brains of MS patients, and uncovered patterns regarding which areas of the brain are … Continue reading AI identifies three subtypes of multiple sclerosis in MRI brain scans

Samsung’s more precise SmartTag+ uses AR to guide you to lost items

Trackers like Tile or Pixie have been helping us find lost keys and wallets for years now, but they aren’t all that precise beyond “it’s within Bluetooth range.” Samsung has now unveiled the Galaxy SmartTag+, the first tracker to use the more accurate … Continue reading Samsung’s more precise SmartTag+ uses AR to guide you to lost items

Natural brilliant blue food coloring wrung out of red cabbage

It may seem like a basic color, but blue is actually rather rare in the natural world. That complicates the search for natural blue food colorings, but now a team of scientists has found a promising candidate hiding in red cabbage.Continue ReadingCateg… Continue reading Natural brilliant blue food coloring wrung out of red cabbage

Protein bath helps “recellularize” organs for safer transplants

Organ transplants save lives, but complications can arise if the recipient’s immune system rejects the foreign cells. An emerging technique reduces that risk by stripping the donor cells out of the donor organ and replacing them with the recipient’s ow… Continue reading Protein bath helps “recellularize” organs for safer transplants

Microsoft’s new cooling system dunks data servers in boiling liquid

Liquid cooling is one of the most effective ways to keep computers from overheating. While the natural first choice might be a liquid that runs cold, Microsoft has now done the exact opposite, demonstrating a system to cool its cloud servers by dunking… Continue reading Microsoft’s new cooling system dunks data servers in boiling liquid

Bacterial “homing missiles” could unlock new antibiotic treatments

Microscopic wars are constantly raging all around, on and inside us, as bacteria fight for resources and room. They’ve developed some crafty weapons in the process, such as tailocins, which act somewhat like “homing missiles” against their enemies. Now… Continue reading Bacterial “homing missiles” could unlock new antibiotic treatments

Experimental oral pills auto-release insulin when glucose levels are high

Daily injections of insulin are a hassle for the hundreds of millions of people with diabetes. An oral pill would be much easier to swallow (pun intended), and now researchers from New York University Abu Dhabi have developed a new method for packing i… Continue reading Experimental oral pills auto-release insulin when glucose levels are high

Smart stent coatings release drugs for better artery healing

Scientists have developed a new type of smart stent that can help prevent some of the complications these implants bring. The stent is coated in a substance that minimizes the inflammatory response, while promoting tissue repair.Continue ReadingCategor… Continue reading Smart stent coatings release drugs for better artery healing

“Magnetic” dark matter may be accelerating the universe’s expansion

The expansion of the universe is accelerating, but we’re not really sure why. The current best models give the driving force the placeholder name of “dark energy” – but that might not even exist. A new study has found that if dark matter had some unusu… Continue reading “Magnetic” dark matter may be accelerating the universe’s expansion
