Researchers have developed a new kind of “x-ray vision”—a way to peer inside real-world devices such as batteries and catalysts to map the internal nanostructures and properties of the various components, and even monitor how properties evolve as the devices operate.
Scientists at the University of Wisconsin-Madison have made a discovery that, if replicated in humans, suggests a shortage of zinc may contribute to diseases like Alzheimer’s and Parkinson’s, which have been linked to defective proteins clumping together in the brain.
Geologists found that the likelihood that tungsten will seep into an aquifer's groundwater depends on the groundwater's pH level, the amount of oxygen in the aquifer and the number of oxidized particles in the water and sediment.
Genes in mitochondria, the “powerhouses” that turn sugar into energy in human cells, shape each person’s risk for heart disease and diabetes.
University of Virginia researchers have found that the Marcellus Shale geological formation in Pennsylvania has the potential to store roughly 50 percent of the U.S. carbon dioxide emissions produced from stationary sources between 2018 and 2030.
Breaking Bad is wrapping up this week and with Walter White's life collapsing around him, it begs the question: Is "Heisenberg’s" science up to snuff? We put that question to some of Dalhousie's scientific experts.
Chemists from Iowa State and the Ames Laboratory are part of a research team that discovered where a protein binds to plant cell walls, a process that makes it possible for plants to grow. The discovery could lead to bigger harvests for bioenergy.
Candida albicans is a double agent: In most of us, it lives peacefully, but for people whose immune systems are compromised by HIV or other severe illnesses, it is frequently deadly. Now a new study from Johns Hopkins and Harvard Medical School shows how targeting a specific fungal component might turn the fungus from a lion back into a kitten.
Sandia National Laboratories researchers are studying the movement of iodine-129 from spent nuclear fuel through a deep, clay-based geological repository. Understanding the process is crucial as countries worldwide consider underground clay formations for nuclear waste disposal.
Researchers have reported the first experimental evidence that supports the theory that a soccer ball-shaped nanoparticle commonly called a buckyball is the result of a breakdown of larger structures rather than being built atom-by-atom from ground up.
In synthetic chemistry, making the best possible use of the needed ingredients is key to optimizing high-quality production at the lowest possible cost. The element rhodium is a powerful catalyst — a driver of chemical reactions — but is also one of the rarest and most expensive. In addition to its common use in vehicle catalytic converters, rhodium is also used in combination with other metals to efficiently drive a wide range of useful chemical reactions.
Now, research from UNC School of Medicine biochemist Charles Carter, PhD, appearing in the September 13 issue of the Journal of Biological Chemistry, offers an intriguing new view on how life began.

A new study — the first to apply a new screening technique to human platelets — netted a potential drug target for preventing dangerous blood clots in high-risk people.
For many migraine sufferers, bright lights are a surefire way to exacerbate their headaches. And for some night-shift workers, just a stroll through a brightly lit parking lot during the morning commute home can be enough to throw off their body's daily rhythms and make daytime sleep nearly impossible. But a new molecule that selectively blocks specialized light-sensitive receptors in the eyes could help both these groups of people, without affecting normal vision.
Scientists at The Scripps Research Institute (TSRI) have found a way to apply a powerful new DNA-editing technology more broadly than ever before. “This is one of the hottest tools in biology, and we’ve now found a way to target it to any DNA sequence,” said Carlos F.

The American Chemical Society, the world’s largest scientific society, is holding a symposium on those substances during its 246th National Meeting & Exposition.
Mention cars that get barely 3 miles to a gallon and are built for speed rather than cleanliness, and images of gas-guzzling, pollution-belching menaces burning leaded gasoline or nitro may spring to mind. But experts today described how ethanol blends used as fuel in the race cars of the Indianapolis 500 actually make those emissions cleaner than cars on the street. They spoke at the 246th National Meeting & Exposition of the American Chemical Society.
One of the first analyses of laws banning disposal of electronic waste (e-waste) in landfills has found that state e-waste recycling bans have been mostly ineffective, although California’s Cell Phone Recycling Act had a positive impact. However, e-waste recycling rates remain “dismally low,” and many demographic groups remain unaware of their alternatives, according to the study, which was presented today at the 246th National Meeting & Exposition of the American Chemical Society.

A somber picture of the struggle against super-weeds emerged here today as scientists described the relentless spread of herbicide-resistant menaces like pigweed and horseweed that shrug off powerful herbicides and have forced farmers in some areas to return to hand-held hoes. The reports on herbicide resistance and its challenges to modern agriculture were part of a symposium at the 246th National Meeting & Exposition of the American Chemical Society.
Evidence from people with heart disease strongly supports the existence of the molecular link first discovered in laboratory mice between the body’s natural circadian rhythms and cardiac arrest or sudden cardiac death — the No. 1 cause of death in heart attacks, a scientist said here today at the 246th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

The scientist who turned fresh-cut apple slices into a popular convenience food, available ready-to-eat in grocery stores, school cafeterias and fast-food restaurants, today described advances in keeping other foods fresh, flavorful, and safe for longer periods of time through the use of invisible, colorless, odorless, tasteless coatings. The overview of these edible films was part of the 246 National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.
Honey bees should be on everyone’s worry list, and not because of the risk of a nasty sting, an expert on the health of those beneficial insects said here today at the 246th National Meeting & Exposition of the American Chemical Society. Despite years of intensive research, scientists do not understand the cause, nor can they provide remedies, for what is killing honey bees.
“Biofuel” is a global buzzword, with cars and trucks powered by fuel made from corn, switchgrass and waste cooking oil, envisioned as a way to stretch out supplies of crude oil and cope with global warming. A symposium being held here today at the 246th National Meeting & Exposition of the American Chemical Society considers: What are the health and environmental effects of alternative fuels, and how do they compare with conventional fuels?
With the “Valley of Death” looming as an increasingly serious obstacle to introducing better ways of preventing, diagnosing and treating diseases, a noted scientist today described a new approach for moving promising drug compounds out of laboratories and into the hands of patients and physicians.

Unlikely as it may sound, giant pandas Ya Ya and Le Le in the Memphis Zoo are making contributions toward shifting production of biofuels away from corn and other food crops and toward corn cobs, stalks and other non-food plant material. Scientists presented an update today on efforts to mine Ya Ya and Le Le assets for substances that could do so during the 246th National Meeting & Exposition of the American Chemical Society.
In an advance in determining the role of environmental agents in causing cancer, scientists described discovery of a long-sought way to use biopsy samples from cancer patients to check on human exposure to substances that damage the genetic material DNA in ways that can cause cancer. Their report on the method, which taps into a treasure trove of information left by biopsy patients, was part of the 246th National Meeting of the American Chemical Society.
