Bacteria could travel from the nose to the brain and trigger Alzheimer’s

A new study has found that nose bacteria can make their way into the brain through nerves, and could lead to Alzheimer’s disease. The work adds to the growing body of evidence that Alzheimer’s may be triggered through viral or bacterial infections.

Physicists measure gravitational time warp to within one millimeter

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest distance yet.

Astronomers discover new type of star with puzzling origins

Astronomers have discovered a new type of star, and exactly how these weird white dwarfs came to be remains a mystery. They're covered in a layer of “ash” that’s usually produced by burning helium, indicating they may have formed as other stars collided.

Bio-composite combines hardness of aluminum with toughness of bone

When it comes to plant-based materials, many people may picture something that's "green" but not very robust. Such is not the case with a new MIT-designed composite, however, which is claimed to be as hard as aluminum and as tough as bone.
