Synthetic biologists hack bacterial sensors

Rice University synthetic biologists have hacked bacterial sensing with a plug-and-play system that could be used to mix-and-match tens of thousands of sensory inputs and genetic outputs. The technology has wide-ranging implications ...

Virulence factor of the influenza A virus mapped in real-time

The influenza A viruses, which are responsible for deadly pandemics in the past, still remain a major global public health problem today. Molecules known as virulence factors are produced by bacteria, viruses, and fungi to ...

Producing F-18 radiopharmaceuticals for PET imaging

Recently ANSTO researchers have made progress investigating improved ways to make life-saving radiopharmaceuticals using the fluorine-18 radioisotope so they can be available in more hospitals at lower cost.

Metals influence C-peptide hormone related to insulin

Metals such as zinc, copper and chromium bind to and influence a peptide involved in insulin production, according to new work from chemists at the University of California, Davis. The research is part of a new field of "metalloendocrinology" ...

Engineered microbial production of grape flavoring

Researchers report a microbial method for producing an artificial grape flavor. Methyl anthranilate (MANT) is a common grape flavoring and odorant compound currently produced through a petroleum-based process that uses large ...

Designing biological movement on the nanometer scale

Synthetic proteins have been created that move in response to their environment in predictable and tunable ways. These motile molecules were designed from scratch on computers, then produced inside living cells.

Chemists ID possible addiction-free pain reliever

An estimated 1.7 million Americans suffer from substance abuse disorders related to opioid use for pain relief, according to the National Institute on Drug Abuse. This causes an economic burden of more than $78 billion per ...

Ragweed compounds could protect nerve cells from Alzheimer's

As spring arrives in the northern hemisphere, many people are cursing ragweed, a primary culprit in seasonal allergies. But scientists might have discovered a promising new use for some substances produced by the pesky weed. ...

A hydrogel that can stop bleeding from an artery

A team of researchers affiliated with several institutions in China has developed a hydrogel that can stop bleeding from a punctured artery. In their paper published in the journal Nature Communications, the group describes ...

Early in vitro testing for adverse effects on embryos

ETH researchers have combined embryonic cells and liver cells in a new cell culture test. This combination lets them detect adverse effects that new medications may have on embryos early on in the drug development process.

Extreme cold could reveal herpesvirus infection dynamics

The funny thing about the virus that causes chicken pox is that no one knows for sure how it or many of its herpesvirus cousins invade and infect cells. It's a bit of a problem: Without that knowledge, it's been hard to find ...
