Researchers develop solid-state, free-standing carbon nanofiber supercapacitor

A group of Drexel University researchers have created a fabric-like material electrode that could help make energy storage devices—batteries and supercapacitors—faster and less susceptible to leaks or disastrous meltdowns. Their design...Show More Summary

Ensuring broccoli sprouts retain their cancer-fighting compounds

Raw broccoli sprouts, a rich source of potential cancer-fighting compounds, have become a popular health food in recent years. But conventional heat treatment used to kill bacteria on produce can reduce levels of the broccoli sprouts' helpful phytochemicals. Show More Summary

Lipid vesicles replace blood in new bacteria test

As schools around the U.S. start back up, so do trips to the doctor's office. But is that raw sore throat due to bacteria, which can be fought off with antibiotics, or a virus? Getting a definitive diagnosis of bacterial infections like Strep throat can take days. Now, one group reports in ACS Sensors that they have developed a new test that will provide results in just hours.

Novel small antibody fragment—a valuable tool in crystallography

Antibodies are a powerful weapon system in defending our body against invaders such as bacteria and viruses. Each antibody consists of four amino acidpolypeptide chains: two heavy chains and two light chains joined to form a Y-shaped molecule. Show More Summary

More mouths can be fed by boosting number of plant pores

Environmental studies have shown that 40% of the atmospheric carbon dioxide (CO2) passes through plant stomata every year. Thus, controlling stomatal development and function is considered as a key for increasing crop plant productivity and water-use efficiency. Show More Summary

Naked molecules dancing in liquid become visible

Capturing the movement of molecules is not an easy task. Scientists at the Center for Soft and Living Matter, within the Institute for Basic Science (IBS) were able to observe the movement of molecules stored inside a graphene pocket without the need to stain them. Show More Summary

Technique could make it easier to use mRNA to treat disease or deliver vaccines

By delivering strands of genetic material known as messenger RNA (mRNA) into cells, researchers can induce the cells to produce any protein encoded by the mRNA. This technique holds great potential for administering vaccines or treating diseases such as cancer, but achieving efficient delivery of mRNA has proven challenging.

Team develops gas-sensing technology that could revolutionize environmental and medical diagnostics

Relying on nanotechnology, scientists from Russia and Germany led by Skoltech research scientist Fedor Fedorov have developed an innovative solution for detecting traces of gas in the air.

New infrared imaging technique reveals molecular orientation of proteins in silk fibres

A large international collaboration has used a specialised technique on the infrared microspectroscopy (IRM) beamline at the Australian Synchrotron to determine the structure of proteins in individual silk fibres that has potential use in the design of new biomaterials with desirable properties.

Complex life evolved out of the chance coupling of small molecules

Complex life, as we know it, started completely by chance, with small strands of molecules linking up, which eventually would have given them the ability to replicate themselves.

New biomaterial could replace plastic laminates, greatly reduce pollution

An inexpensive biomaterial that can be used to sustainably replace plastic barrier coatings in packaging and many other applications has been developed by Penn State researchers, who predict its adoption would greatly reduce polluti...

Supercontinuum lasers can lead to better bread and beer

Researchers from the Department of Food Science (FOOD) at the University of Copenhagen in Denmark are the first in the world to have analysed whole grains with long near-infrared wavelengths using a new type of light source, the supercontinuum laser. Show More Summary

Slowing the clockwork

Progress on the way to smart nanomachines: LMU chemists have modified the synthesis of a molecular motor so as to reduce the speed of its light-driven rotation, thus permitting the researchers to analyze the mechanism of motion in complete detail.

Device for measuring inflammation at home

VTT Technical Research Centre of Finland has developed a portable device for measuring inflammation levels quickly in home environment.

Nanocapsules enable cell-inspired metabolic reactions

Researchers at the University of Basel succeeded in developing capsules capable of producing the bio-molecule glucose-6-phosphate that plays an important role in metabolic processes. The researchers were able to produce the metabolite in conditions very similar to the biochemical reaction inside natural cells. Show More Summary

Destabilization processes in foam

Oktoberfest is an exciting cultural event, but it is also a source of inspiration for materials scientists and engineers. Not the beer itself, but rather the beer foam is a source of inspiration.

Self-healing catalysts make it easier to store solar energy with water

(Phys.org)—Currently one of the most efficient ways to store solar energy is to transfer the energy to catalysts that split water into hydrogen and oxygen. Then the hydrogen can either be used as a fuel or later recombined with oxygen to produce water and release electricity when needed.

Scientists find way to remove 'noise' from big data in metabolomics study

Not long ago, scientists placed wagers on the number of genes in the human genome. Some bets ranged upward of 100,000 genes being present. Once the human genome sequence was completed, a project led in part by the McDonnell Genome Institute at Washington University School of Medicine in St. Louis, even the lowest guess of 25,947 proved to be above the true number.

An effective way to eliminate atrazine and its byproducts in surface water

Atrazine, widely used as a weedkiller, is known to have harmful effects on aquatic wildlife and presents a risk to human health by altering the action of certain hormones. In a study published recently in Water Research, a team of researchers...Show More Summary

Ironing out a puzzle

Alison Butler has never met Canadian chemist and philanthropist Alfred Bader, but they have something important in common.
