Our intestinal microbiome influences metabolism -- through the immune system
The innate immune system, our first line of defense against bacterial infection, has a side job that's equally important: fine-tuning our metabolism.

Zebrafish's near 360 degree UV-vision knocks stripes off Google Street View
A zebrafish view of the world has been forensically analyzed by researchers to reveal that how they see their surroundings changes hugely depending on what direction they are looking.

Fish's use of electricity might shed light on human illnesses
African weakly electric fish, commonly called baby whales, use incredibly brief electrical pulses to sense the world around them and communicate with other members of their species. Part of that electrical mechanism exists in humans -- and by studying these fish, scientists may unlock clues about conditions like epilepsy.

A mechanism behind choosing alcohol over healthy rewards is found
Changes in a brain signalling system contribute to the development of alcohol addiction-like behaviors in rats, according to a new study. The findings indicate a similar mechanism in humans.

California Aedes mosquitoes capable of spreading Zika
Over the last five years, Zika virus has emerged as a significant global human health threat following outbreaks in South and Central America. Now, researchers have shown that invasive mosquitoes in California -- where cases of Zika in travelers have been a regular occurrence in recent years -- are capable of transmitting Zika.

Caffeine from four cups of coffee protects the heart with the help of mitochondria
A new study shows that a caffeine concentration equivalent to four cups of coffee promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage.

DNA enzyme shuffles cell membranes a thousand times faster than its natural counterpart
A new synthetic enzyme, crafted from DNA rather than protein, flips lipid molecules within the cell membrane, triggering a signal pathway that could be harnessed to induce cell death in cancer cells. This is the first such synthetic enzyme to outperform its natural counterpart -- and it does so by three orders of magnitude.

DNA barcodes that reliably work: A game-changer for biomedical research
Researchers have developed a new method for correcting the errors that creep into DNA barcodes -- labels used in a wide range of biological experiments -- yielding far more accurate results and paving the way for more ambitious medical research in the future.

Rewiring plant defense genes to reduce crop waste
Plants could be genetically rewired to better resist disease, helping safeguard crop yields worldwide according to new research. Defensive feedback control system developed enables plants to strengthen their defenses to withstand attack by re-wiring existing gene connections. The system uses same approach as aircraft autopilots use to counteract turbulence.
