Lithium commonly used to treat bi-polar disorder increases lifespan in Nematode worms

Nematode worms treated with lithium show a 46 percent increase in lifespan, raising the tantalizing question of whether humans taking the mood affecting drug are also taking an anti-aging medication.

Stanford scientists find gene that gives dogs black fur

A discovery about the genetics of coat color in dogs could help explain why humans come in different weights and vary in our abilities to cope with stress, a team led by researchers from the Stanford University School of Medicine reports.

Scientists unveil structure of molecular target of many drugs

More than 40 years after beta blockers were first used clinically, scientists can finally get a detailed, three-dimensional look at the drugs' molecular target - the beta2-adrenergic receptor.

Odd protein interaction guides development of olfactory system

Scientists have discovered a strange mechanism for the development of the fruit fly antennal lobe, an intricate structure that converts the chaotic stew of odors in the environment into discrete signals in the brain.

Red hair and freckles - Neanderthals in Europe

Fossil remains of Neanderthals paint an incomplete picture; they cannot tell us about their cognitive skills or give us details of what they looked like.

Scientists discover new causes for neurodegeneration

Diseases that cause neurons to break-down, such as Alzheimer's, Multiple Sclerosis and Creutzfeldt-Jakob disease (Mad Cow Disease), continue to be elusive to scientists and resistant to treatments.

New type of biodegradable nanoparticle for drug delivery

The spherical structures can encapsulate various fat-soluble medicines, which makes it easier to target tumour tissue. These nanoballs are highly promising carriers for the controlled release of anticancer drugs. Rijcken recently gained her doctorate for this research from Utrecht University.

How Rhesus Macaques and Humans have conquered the world

When it comes to their social behavior, people sometimes act like monkeys, or more specifically, like rhesus macaques, a type of monkey that shares with humans strong tendencies for nepotism and political maneuvering, according to research by Dario Maestripieri, an expert on primate behavior and an Associate Professor in Comparative Human Development and Evolutionary Biology at the University of Chicago.

Transparent zebrafish help the study inflammatory breast cancer

What if doctors could peer through a patient's skin and see a cancer tumor growing? They'd be able to study how tumor cells migrate: how they look, how they interact with the blood system to find nourishment to grow and spread through the body.
