Nuclear spectroscopy breakthrough could rewrite the fundamental constants of nature

Raising the energy state of an atom's nucleus using a laser, or exciting it, would enable development of the most accurate atomic clocks ever to exist. This has been hard to do because electrons, which surround the nucleus, react easily with light, increasing the amount of light needed to reach the nucleus. By causing the electrons to bond with fluorine in a transparent crystal, UCLA physicists have finally succeeded in exciting the neutrons in a thorium atom's nucleus using a moderate amount of laser light.

Potential new target for early treatment of Alzheimer's disease

A class of proteins that regulates cell repair and enhances cell growth-signaling systems could be a promising new target for the treatment of Alzheimer's and other neurodegenerative diseases, according to a new study. They found that disrupting necessary sugar modifications of these proteins promotes cell repair and reverses cellular abnormalities that occur in neurodegenerative diseases.

A new breakthrough in understanding regeneration in a marine worm

The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.

A new target for treatment of one type of macular degeneration

A new study in mice hints at the promise of an eventual alternative treatment option for the 'wet' version of age-related macular degeneration (AMD). Researchers determined in mice that an enzyme related to cell growth and division is a culprit in the blood vessel invasion in the back of the eye that causes blurred central vision in wet AMD. Targeting the enzyme, called telomerase, with an experimental drug suppressed abnormal vascular growth in the animals' retina.
