Japanese chemists develop vicinal reaction for creating highly functionalized ketones

Organic chemists are molecular architects, designing sophisticated structures. As the molecules used in science and medicine become ever more complex, new tools are needed to piece together the building blocks.

Discovery of 'cellular bike couriers' could shed light on disease spreading mechanisms

A previously unknown component of our cells that delivers proteins like a bike courier in heavy traffic could shed light on the mechanisms that allow cells to spread in diseases such as cancer.

Creating ‘green’ antibiotics from the waste products of Greek yogurt

The modern biomedical industry requires new approaches to the production of antimicrobials. The use of by-products from the food industry could represent a new and interesting development in the field of antibiotic production.

KAUST researchers one step closer to understanding brain function

Researchers at King Abdullah University of Science and Technology (KAUST) are officially one-step closer to understanding the brain and its function.

Scientists solve first structure of human cotransporter protein KCC1

In work that could someday improve treatments for epilepsy, UT Southwestern scientists have published the first three-dimensional structure of a member of a large family of human proteins that carry charged particles – ions – across the cell membrane.

Some plant foods causing paralysis, death, in malnourished populations

There are a lot of plants eaten for food that may also contain toxins that harm the brain and the nervous system, when present in amounts that cross the limit of individual tolerance. This happens when such toxin-containing foods are the chief or only source of nutrition.

Researchers use 3D electron microscopy to unravel dense networks in the cerebral cortex

Unlike any other organ, our brains contain extremely densely packed networks of membranous cables that are used by our about 86 billion nerve cells for communication amongst each other.

Columbia researchers capture new detailed images of a temperature-sensing molecule

Columbia University researchers have captured new detailed images of a temperature-sensing molecule in its open, intermediate, and closed states.

Discovery about DNA-reeling bacteria can help inform strategies to stop bacterial infection

A new study from Indiana University has revealed a previously unknown role a protein plays in helping bacteria reel in DNA in their environment -- like a fisherman pulling up a catch from the ocean.

Blue light and fruit flies: a warning for humans

A new study involving the fruit fly, Drosophila melanogaster, published in the journal npj Aging and Mechanisms of Disease, shows that when flies are kept in darkness, or in white light from which the blue spectrum has been excluded, they live longer, compared to flies kept in alternating 12-hour shifts of blue LED light and darkness. The reason appears to be a speeded-up version of aging; the brain cells, retinal cells and climbing ability, all suffer a breakdown.

New technique reveals how the brain responds to light signals received by the retina

In recent decades, scientists have learned a great deal about how different neurons connect and send signals to each other. But it's been difficult to trace the activity of individual nerve fibers known as axons, some of which can extend from the tip of the toe to the head.

Glycans in mucus are responsible for microbe-taming, study reveals

More than 200 square meters of our bodies -- including the digestive tract, lungs, and urinary tract -- are lined with mucus. In recent years, scientists have found some evidence that mucus is not just a physical barrier that traps bacteria and viruses, but it can also disarm pathogens and prevent them from causing infections.

Understanding protein aggregation over time can help decipher early stages of Parkinson's

One of the biggest difficulties in treating Parkinson's disease, a progressive neurodegenerative disorder, is the understanding of when it starts.

Structural biology reveals 3D structure of asthma-linked receptor

A new study has laid bare the structure of a protein receptor called the CysLT1 receptor that is implicated in a range of allergic and cardiovascular conditions as well as some types of cancer. Published in Science Advances, the paper shows how the researchers used structural biology techniques to accomplish this feat.

New liquid-cell technology provides first 3D view of life’s processes

A new liquid-cell technology allows scientists to see biological materials and systems in three dimensions under an electron microscope (EM), according to researchers at Penn State, Virginia Tech and Protochips Inc.

Scientists uncover details of antibody response to Ebola virus vaccine

In the recurring, deadly Ebola outbreaks in parts of Africa, today's health workers now have at least some tools to fight the disease: vaccines. Vaccines against Ebola have been administered to over 100,000 people to date, but they are barely out of the experimental stage.

Scientists decode molecular architecture of secretion systems involved in tuberculosis

Tuberculosis is a highly contagious infectious disease that is typically spread through aerosols and mainly affects the lungs. According to the World Health Organization (WHO), an estimated 1.7 million people die from such an infection worldwide every year.

New insight into presynaptic distribution and profile of mitochondria in calyx of Held

The ability to hear relies on neurons to constantly transmit information at very rapid timescales. This rapid rate of information transmission results in intense energetic demands. Within our cells, microscopic power plants called mitochondria provide the main source of energy keeping our bodies moving.

Researchers determine how the colon prioritizes gas detox over energy use

Onions, cabbage, garlic. While nutritious, eating these foods can lead to an embarrassing side effect: smelly flatulence. More than just smelly, hydrogen sulfide, the chemical compound responsible for the rotten-egg aroma, is deadly if inhaled at doses of more than 700 parts per million.
