A new study finds wine-derived human gut metabolites may have neuroprotective capabilities.Low to moderate intake of red wine can delay the onset of neurodegenerative diseases such as Alzheimer's and Parkinson's. Researchers have now found out how wine compounds are protective against neuronal death: they should pass through your stomach first.

Using fruit flies, Johns Hopkins researchers say they have identified a specific and very small set of brain cells—dubbed dopamine wedge neurons—responsible for driving the insects' food preferences toward what they need, rather than what they like.

What to consider when making a cardio choice

The bionic eye just got a lot more eye-friendly.

As animals increasingly acquire interacting mutations that result in loss of gene function, the relative decline in their fitness may only be exacerbated, a new study in humans and fruit flies suggests.

Novel proteins, created from scratch with no particular design in mind, can sometimes do the work of a natural protein. The discovery may widen the toolkit of synthetic biologists trying to build bespoke organisms.

For a healthy body full of ‘good’ bacteria, you may need to do a lot more than eat a probiotic yoghurt, as Adam Rutherford discovered when he took a rather uncomfortable test.

To explore these possibilities, the Defence Advanced Research Projects Agency (DARPA) has just awarded more than an estimated US$50 million in funding to eight teams looking into how electrical stimulation of the nervous system can help facilitate learning.
