Study: Showering boosts concentrations of potentially hazardous trihalomethanes

CHAPEL HILL -- Trihalomethanes -- byproducts of interaction between chlorine used to disinfect water and organic matter found in raw water -- increase significantly in the bloodstream after showering, a new study shows. Public health experts suspect the chemicals may boost the risk of cancer an...

DEET brain effects in animals warrant caution

...and damage consistent with the presence of harmful byproducts called oxygen free radicals (also known as reactive oxygen species), which can damage DNA and cell membranes in the brain and the nervous system. The most severe brain cell changes and sensorimotor deficits were seen among rats exposed to combinatio...

Don't be fooled about your oral health: AAP uncovers common misconceptions

... When the gums are infected, periodontal bacterial byproducts can enter the blood stream and travel to major organs and set off other problems. Research suggests this may: contribute to the development of heart disease, the nation's leading cause of death; increase the risk of stroke; increase a woman's risk o...

Dietary supplements make old rats youthful, may help rejuvenate aging humans, according to UC Berkeley study

...s the accumulation of destructive free radicals - byproducts of normal metabolism - that disable enzymes and other chemicals. The combination therapy targets mitochondria to get rid of destructive radicals and to boost the activity of a damaged enzyme, carnitine acetyltransferase, that plays a key role in burn...

Engineers develop odour eaters for pulp mills

...echniques that use bacteria to "eat" air pollutant byproducts from the pulp process and thereby filter out the smell. "All industrial processes have air emissions and, in the case of pulp and paper mills, the smell can be quite overwhelming. This biofilter operates like a mini ecosystem. It's a microbial commun...

Chlorophyllin reduces Aflatoxin indicators among people at risk for liver cancer

...greatly reduces the levels of aflatoxin-DNA damage byproducts in the body, which are indicators of exposure to carcinogenic aflatoxins and increased risk of liver cancer. Chlorophyllin is a derivative of chlorophyll and is used as an over-the-counter diet supplement and as a food colorant. The results appear in...

Study examines how prion disease adapts to new species

... the practice of giving animals feed made from the byproducts of other animals. Some evidence suggests that cattle in the United Kingdom contracted mad cow when they ate feed made from the bone meal of sheep infected with scrapie. Cows are no longer given such feed, but other farm animals are, the researchers...

MIT chemist wins national award for catalyst research

...o simply [the reactions are] fast, clean, with no byproducts or residue, Schrock said. Without them, our syntheses would be far longer and embarrassingly inefficient, wrote a colleague to support his nomination for the award. It would be difficult to identify another organometallic chemist who has more profoun...

Rutgers biologist wins a $1.03 million, 5 year contract to study how microbes can help clean up Superfund sites

... metals arsenic and chromium, as well as petroleum byproducts such as benzene, toluene and xylene often found mixed with the metals in hazardous waste sites. She also plans to learn which types of bacteria are most effective and the best way to use them. "To what extent do they reduce arsenic and ...

ORNL technology puts power of lab into the field

...and a photo sensor to detect toxic chemicals, TNT, byproducts from explosives, drugs and hundreds of chemicals. The material can be in liquid or powder form. Raman technology involves illuminating a sample with a laser beam and measuring the reflected light. The light shows the vibration energies, which are uni...

New study could lead to better treatment of septic shock

...d circulation and free radicals, harmful chemical byproducts created during an immune system response. Both are produced in abundance during septic shock. Studies suggest that the potent combination produces a substance called peroxynitrite, which causes a normal immune response to go haywire, damaging bl...

Small streams contribute far more than previously thought to cleaning waterways

...urces, including runoff from residential lawns and byproducts of automobile combustion, taking greater care to insure that small streams can work effectively to clean the water will reduce the overall nitrogen load that makes its way into larger bodies of water. "It doesn't mean that you can ignore you...

New study reveals a major cause of global warming - ordinary soot

...such as carbon dioxide and methane, which also are byproducts of fossil fuel burning. But according to IPCC scientists, atmospheric soot has relatively little effect on world climate. Jacobson disagrees. ``Only a handful of studies have considered the impact of soot on global warming,`` he says, ``and most of...

On a daily basis we are exposed to UV light, which can introduce covalent bonds between adjacent bases in DNA, thereby altering the normal double-helical shape of DNA and blocking its replication. Whether or not this DNA d...

INEEL creates a method to link energy use, greenhouse gases

...t other environmental gases were created either as byproducts or in other processes, and what environmental factors either mitigated or exacerbated its effect. For example, the INEEL buys a large portion of its electricity from utilities that are hydropower-based. Therefore, a smaller amount of carbon is rel...

Researchers develop tastier low-fat cheddar

...ents to his group's low-fat cheddar. The metabolic byproducts of the bacterial micro-organisms, and the way they interact during cooking, release certain enzymes that appear to degrade or destroy substances that your taste buds find less savory. For example, bitterness, a common off-flavor in reduced-fat cheese...

Creating a standard spectrum of smell

Environmental technology-based industries will develop new equipment, applications and services related to drinking water. And the federal and provincial governments could use the results to strengthen guidelines for the protection ...

Study details genetic basis of aging -- and how it might be delayed

...o energy. In the process of metabolism, some toxic byproducts are produced, damagingproteins and triggering a stress response that acts to repair damaged moleculesand that seems to be governed by a few select genes. But with age, the body'sability to repair damaged proteins declines, possibly as a result of shr...
