New insight into methanotrophs, bacteria that can oxidize methane, may help us develop an array of biotechnological applications that exploit methane and protect our environment from this potent greenhouse gas.
Researchers are developing a next generation positron beam facility that will enable them to analyze the properties of advanced materials for future electronics applications, such as ultra compact high-speed computers and ultra small high-powered batteries.
Researchers at Case Western Reserve University and the University of Michigan have produced the first image of an important human protein as it binds with ribonucleic acid (RNA), a discovery that could offer clues to how some viruses, including HIV, control expression of their genetic material.
It is possible to make metabolite maps of living plant tissues both quickly and accurately by using laser ablation electrospray ionization mass spectrometry imaging.
An international team of researchers developed a method that identifies up to twice as many proteins and peptides in mass spectrometry data than conventional approaches. The method can be applied to a range of fields.
At the University of Melbourne, a rare, eight-carat diamond has been smashed to smithereens in a bid to discover the secrets of its origin and a potential "mother lode" of diamonds.
A researcher has developed a new camera color filter that lets in three times more light than conventional filters, resulting in much cleaner, more accurate pictures taken in lowlight. The new filter can be used for any kind of digital camera.
In what they say was a lucky and unexpected finding, researchers at Johns Hopkins say they’ve discovered that male fruit flies lay down an odorant, or pheromone, that not only attracts females to lay eggs nearby, but also guides males and females searching for food.
A new study indicates that the most polluted waters, the ones with the highest levels of bioconcentration, the highest percentage of intersex fish, etc., exist around wastewater treatment plants. Most of these plants are not equipped to eliminate compounds, because legislation in this matter has yet to catch up with the development of the chemical industry.
Just 2 centimeters long and 2 millimeters in diameter, a sorbent tube invented by an FIU researcher could bring analytical chemistry to the masses. The simple yet highly sensitive device is designed to sample volatile chemicals in the air, your home, food and even your body.
A new study led by scientists at The Scripps Research Institute (TSRI) shows that a technology used in thousands of laboratories, gas chromatography mass spectrometry (GC-MS), fundamentally alters the samples it analyzes.
Forensic analysis reveals clues as to what new substances and drugs were introduced to England in the 16th and 17th century from the New World- and if Shakespeare and his contemporaries were taking part in these new activities.
A bioelectronic nose that mimics the human nose can detect traces of bacteria in water by smelling it, without the need for complex equipment and testing. The sensor is simple to use and it can detect tiny amounts of contamination in water, making it more sensitive than existing detection methods.
The Rice lab of chemist Christy Landes invented a technique to characterize such nanoscale spaces, an important advance toward her group’s ongoing project to efficiently separate “proteins of interest” for drug manufacture. It should also benefit the analysis of porous materials of all kinds, like liquid crystals, hydrogels, polymers and even biological substances like cytosol, the compartmentalized fluids in cells.
Biologists at ETH Zurich have developed a method that, for the first time, makes it possible to measure concentration changes of several hundred metabolic products simultaneously, and almost in real-time. The technique could inspire basic biological research and the search for new pharmaceutical agents.
Researchers analyzed Eocene rocks found in the Green River Formation, a lake system extending over parts of Colorado, Utah and Wyoming. These Green River rocks have features that visually indicate the presence of life, and they argue that probes to Mars should identify similar indicators on that planet and double-check them through chemical analysis.
Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have reported a major advance in understanding the biological chemistry of radioactive metals, opening up new avenues of research into strategies for remedial action in the event of possible human exposure to nuclear contaminants.
For decades, a particular class of toxic chemicals was added to everything from clothing to carpeting to fire-fighting foams to make them stain- or water-resistant or nonstick--until scientists discovered the compounds were toxic. But how can we be sure that the raw materials those companies obtain, like the fabric for a shirt, aren't already tainted with them?
A sophisticated imaging technique has allowed scientists to virtually peer inside a 10-million-year-old sea urchin, uncovering a treasure trove of hidden fossils. The international team of researchers from the United Kingdom, Spain and Germany, including Dr Imran Rahman from the University of Bristol, studied the exceptional specimen with the aid of state-of-the-art X-ray computed tomography (CT).
Comet impact on Earth are synonymous with great extinctions, but now research shows that early comet impact would have become a driving force to cause substantial synthesis of peptides– the first building blocks of life. This may have implications for the genesis of life on other worlds.
To lose weight, boost energy or soothe nerves, many consumers turn to dietary supplements. But some of these products contain undeclared substances. To protect consumers from taking something without their knowledge, scientists have developed a technique to determine what secret ingredients could be lurking in these supplements.
