A new, computationally inspired approach has led a team of chemists to re-conceptualize a highly valued catalytic process, dramatically increasing the efficiency of a chemical transformation that selectively produces chiral, or handed, molecules valued for medical and life sciences research.
Engineers have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope. Such a system could greatly improve the efficiency of digital pathology, in which specialists need to review large numbers of tissue samples.
High levels of arsenic in rice have been shown to be associated with elevated genetic damage in humans.
A study that draws upon more than 30 years of research reports that, despite long-held beliefs, there is no association between pre-natal mercury exposure and autism-like behaviors.
Using gold nanoparticles, researchers have devised a new way to turn blood clotting on and off.
Chili peppers contain an activator of heat-sensitive pain receptors. A team has now converted an antagonist in the compound into a light-sensitive regulator of receptors that can differentially modulate the effects of various stimuli.
Engineered microbes could turn the CO2 emitted from natural gas and coal-burning power plants into clean, green and renewable liquid transportation fuels.
New observations from the ALMA telescope have given astronomers the best view yet of how vigorous star formation can blast gas out of a galaxy and starve future generations of stars of the fuel they need to form and grow.
Diagnosing the presence of Yersinia pestis, the cause of plague, may soon be easier than ever before.
Scientists have developed a quick and simple method for connecting and assembling new molecules, paving a new road for synthetic chemistry, material science, chemical biology and even drug discovery.
Artists and craftsmen more than 2,000 years ago developed thin-film coating technology unrivaled even by today’s standards for producing DVDs, solar cells, electronic devices and other products.
A new biosensor, applied to the human skin like a temporary tattoo, can alert marathoners, competitive bikers and other “extreme” athletes when they’re about to “hit the wall.”
Scientists are worried by their new findings showing that several bioaccumulative perfluoroalkyl substances are crossing the blood-brain barrier of polar bears.
The virus that causes cold sores has an internal pressure eight times higher than a car tire, and uses it to literally blast its infectious DNA into human cells.
Researchers have identified a pair of genes that appear to be responsible for allowing a specific strain of bacteria to break down a widely prescribed cardiac drug into an inactive compound, as well as a possible way to turn the process off.
A benign crystal protein, produced naturally by bacteria and used as an organic pesticide, could be a safe, inexpensive treatment for parasitic worms in humans, and provide effective relief to more than a billion people around the world.
Understanding the strength of the shellfish’s underwater attachments could enable better glues and biomedical interfaces.
Specific light wavelengths can manipulate volatile compounds that control aroma and taste in several high-value crops, including petunias, tomatoes, strawberries and blueberries.
Researchers have discovered a new chemical reaction that has the potential to lower the cost and streamline the manufacture of compounds ranging from agricultural chemicals to pharmaceutical drugs.
Concentric hexagons of graphene grown in a furnace represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up— atom by atom.
Scientists have created the thinnest, most efficient absorber of visible light on record. The nanosize structure could lower the cost and improve the efficiency of solar cells.
The first-ever snow line seen around a distant star gives astronomers a great thrill because of what it reveals about the formation of planets and our Solar System's history.
A protein found in the membranes of ancient microorganisms that live in desert salt flats could offer a new way of using sunlight to generate environmentally friendly hydrogen fuel.
A team has developed a computational technique that can predict whether a given compound will be toxic even at a low dose and thus allow alternatives to be found when necessary.
