Liver disease drug could help restore cells damaged

Posted by in categories: biotech/medical, neuroscience

A drug which has been used to treat liver disease for decades could help to restore cells damaged by Alzheimer’s, a new study from the University of Sheffield has found.

The pioneering study, funded by Alzheimer’s Research UK, discovered the drug ursodeoxycholic acid (UDCA) improves mitochondrial dysfunction – which is known to be a causative factor for both sporadic and familial Alzheimer’s disease.

Mitochondria play a pivotal role in both neuronal cell survival and death as they regulate energy metabolism and cell death pathways acting as a cell’s battery.

This Is A Sailboat And Those Are Sails

Posted by in categories: energy, physics

We are undeniably using up what little remains of Earth’s petroleum, and because of that, it’s getting expensive. To reduce fuel costs, shipping companies are turning back to sailboats. Yes, seriously. Sailboats. But they don’t look like any sails you’ve seen before.

You know sails – most of the time big rectangle things, sometimes big triangle things, almost always (but not always-always) made out of cloth. But while those things in the top gif don’t look like your normal sails, that’s what they are. They just don’t work like any sail you’ve ever seen before.

Most sails you’ve seen rely on the wind directly acting against them to provide propulsion. But these new types of sails, known as “rotor sails” rely on a physics principle called the Magnus Effect. Here, I’ll let the people with delightfully thick Finnish accents from Norsepower, the company that makes them, explain it:

Scientists Have Found Secret Tunnels Between The Skull And The Brain

Posted by in categories: biotech/medical, neuroscience

Did you know you have tiny tunnels in your head? That’s OK, no one else did either until recently! But that’s exactly what a team of medical researchers have just found in mice and humans — tiny channels that connect skull bone marrow to the lining of the brain.

The research shows they may provide a direct route for immune cells to rush from the marrow into the brain in the event of damage.

Previously, scientists had thought immune cells were transported via the bloodstream from other parts of the body to deal with brain inflammation following a stroke, injury, or brain disorder.
