New research into the changing ecology of thousands of shallow lakes on the North Slope of Alaska suggests that in scenarios of increasing global temperatures, methane-generating microbes, found in thawing lake sediments, may ramp up production of the potent greenhouse gas– which has a global warming potential 25 times greater than carbon dioxide.
To better understand the variety of Salmonella species harbored by captive reptiles, the Staten...
Scientists have recently discovered a link between inflammation and depression, which affects...
The editors of Laboratory Equipment want you to start your week with a smile on your face. With years of science experience, we've heard every science joke there is. So, here’s a science joke you might like. Q: What is the name of the molecule bunny-O-bunny?
Monsanto Co. has agreed to pay $600,000 in fines for not reporting hundreds of uncontrolled releases of toxic chemicals at its eastern Idaho phosphate plant. The EPA and the U.S. DOJ announced the agreement involving the biotechnology company's Soda Springs facilities.
One infrared scan can give pathologists a window into the structures and molecules inside tissues and cells, enabling fast and broad diagnostic assessments, thanks to an imaging technique. Using a combination of advanced microscope imaging and computer analysis, the new technique can give pathologists and researchers precise information without using chemical stains or dyes.
Researchers have created a transparent nanoscale capillary out of graphene to investigate the atomic structure of water trapped inside. They used high magnification electron microscopy that allowed them to see individual water molecules. To their surprise, the scientists found small square crystals of ice at room temperature, provided the graphene capillaries were narrow enough, allowing no more than three atomic layers of water.
The AIDS virus can genetically evolve and independently replicate in patients' brains early in the illness process. An analysis of cerebral spinal fluid, a window into brain chemical activity, revealed that, for a subset of patients, HIV had started replicating within the brain within the first four months of infection.
New research concludes that there is limited evidence to show that xylitol is effective in preventing dental cavities in children and adults. Xylitol is a natural sweetener that is widely promoted globally, and can be found in wide range of everyday products including sugar-free chewing gum, toothpaste, gels, lozenges and sweets.
Newly published research details a discovery explaining why the 100 million Americans estimated to be taking prescription and over-the-counter antacid and heartburn medications may be at an increased risk of bone fractures.
A plastic used in filters and tubing has an unusual trait: it can produce electricity when pulled or pressed. This ability has been used in small ways, but now researchers are coaxing fibers of the material to make even more electricity for a wider range of applications from green energy to "artificial muscles."
Orchestrated costume changes make it possible for certain nasty microbes to outsmart the immune system, which would otherwise recognize them by the telltale proteins they wear. By taking the first detailed look at how one such parasite periodically assumes a new protein disguise during a long-term infection, research challenges many assumptions about one of the best-known examples of this strategy.
A pocket-sized device that can rapidly determine the sequence of an organism's DNA has shown its potential in disease detection. In the first analysis of its kind, researchers were able to use the device to accurately identify a range of closely related bacteria and viruses within six hours, demonstrating the potential for this technology to be used as a mobile diagnostic clinic during outbreaks.
Scientific literature traces manhole explosions back nearly a century, but a series of such incidents in Indianapolis has authorities looking for a quick solution. A combination of power system design, winter road salt, older electrical cable insulation and basic chemistry have triggered underground explosions in older downtowns, launching 350-pound manhole covers high in the air.
Effective lab-based tests are required to eliminate the need for animal testing in assessing the toxicological effects of inhaled chemicals and safety of medicines. A 3-D model of human respiratory tissue has been shown to be an effective platform for measuring the impact of chemicals, like those found in cigarette smoke, or other aerosols, on the lung.
Antimicrobial resistance is a major health care problem worldwide. In the first installment of a new series in The BMJ, a professor asks why authorities are approving drugs with little evidence they do anything to tackle the problem of antimicrobial resistance.
Drugmakers are pouring billions into developing treatments for rare diseases, which once drew little interest from the industry but now point the way toward a new era of innovative therapies and big profits. The investments come as researchers harness recent scientific advances, including the mapping of the human genome, sophisticated and affordable genetic tests and robots that screen thousands of compounds per hour.
Water-borne algal blooms from farm fertilizer runoff can destroy aquatic life and clog rivers and lakes, but scientists are working on a way to clean up these environmental scourges and turn them into useful products. The algae could serve as a feedstock for biofuels, and the feedstock leftovers could be recycled back into farm soil nutrients.
Inspired by the popular "USDA organic" label, House Republicans are proposing a new government certification for foods free of genetically modified ingredients. The idea is part of an attempt to block mandatory labeling of foods that include genetically modified organisms, or GMOs.
Scientists have looked at the effect of low levels of manganese, a common industrial pollutant, on the behavior of honey bees. At levels considered safe for human food, the metal seemed to addle bees. The bees advanced through age-related work assignments faster than normal, yet completed fewer foraging trips than their sisters who were not exposed to manganese.
The sweet taste and smell of antifreeze tempts children and animals to drink the poisonous substance, resulting in thousands of accidental poisonings in the U.S. every year. But today, researchers are describing a new, nontoxic product based on a common food additive that could address this health issue and help the environment at the same time.
The Supreme Court is taking up a challenge by industry groups and Republican-led states that want to roll back Obama administration environmental rules aimed at reducing power plant emissions of mercury and other hazardous air pollutants that contribute to respiratory illnesses, birth defects and developmental problems in children.
Two separate studies have found that air pollution is linked to a higher risk of stroke, particularly in developing countries, and is associated with anxiety. Stroke is a leading cause of death and kills around 5 million people each year worldwide. Anxiety is the most common psychiatric disorder and globally affects around 16 percent of people at some point in life.
Three organic food companies that use spinach in their food have recalled hundreds of thousands of items over listeria concerns. And, Blue Bell is expanding the recall of some ice cream products to include 3-ounce cups of chocolate, strawberry and vanilla ice cream that have tab lids because of possible exposure to the listeria bacteria.
Improving the efficiency of the current wastewater cleaning process, using membrane filtration and oxidation, can remove more than 95 percent of contaminants, such as drug residues and pesticides, from water. The results show that these technologies remove up to 99 percent of contaminants and nutrients.
The nutritional benefits of breast milk for babies are widely documented, but many new mothers find it difficult or are unable to breastfeed. This pushes some mothers to purchase human breast milk on the Internet. Despite appearing as healthy and beneficial products, many new mothers— and even some healthcare workers— are not aware that this market is dangerous because it is not regulated.
Kansas farmers are paying for genetic research to figure out exactly why some people struggle to digest wheat. The hard science is aimed at developing new varieties of wheat at a time when the gluten-free industry is worth nearly a billion dollars a year in the U.S. alone.
Natural gas that is leaked into the atmosphere could speed global warming and climate change. Now, researchers are presenting new and different techniques to make atmospheric observations that are being used to locate, quantify and attribute sources of leaked methane emissions.
