Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless
... cellular DNA, thus rendering them inert. They actually
convert known carcinogens to non-toxic chemicals, and studies have shown a correlation between deficient expression of these enzymes and increased risk of developing some cancers, Chow said. Expression of this enzyme varies dramatically in people ...
X-ray images help explain limits to insect body size
...ps confirm the hypothesis that the tracheal system actually
limits how big insects can be. The research provides a specific explanation for what limits size in beetles: the constriction leading to the legs. A collaborative team of researchers from Argonne's Advanced Photon Source (APS), Midwestern Universit...
Abnormal fat metabolism underlies heart problems in diabetic patients
...diabetic heart tissue, diabetic heart muscle cells actually
take in excess lipids. But as these lipids enter cells they activate lipid-digesting enzymes. In previous studies, Gross and colleagues identified a particular lipid-digesting enzyme that becomes more active in diabetic heart muscle and contributes t...
Circadian clock controls plant growth hormone
... for daylight. A circadian response to auxin was actually
observed in 1937 but then forgotten for 70 years, Harmer said. The researchers hope to understand exactly why having a functional internal clock is important for plant health. ...
Smokeless tobacco more effective than cigarettes for delivering dangerous carcinogens into the body
...to support the notion that the oral use of tobacco actually
provides a more efficient means for delivering certain carcinogens into the body through the bloodstream, although cigarette smoke includes a host of carcinogenic products that arent a major factor in smokeless tobacco, Hecht said. The study partic...
Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
...lead to a viscous feedback of carbon exchange that actually
fuels future climate change. The loss of permafr..., and so on, she said. But what the researchers actually

OHSU turns mouse into factory for human liver cells
...y current technology, such as computer models. You actually
have to see what human liver cells do with any given drug." And human liver cells must be used instead of cells from laboratory animals because liver enzymes that break down these compounds are species specific. "Animal liver cells process drugs qu...
Antioxidant overload may underlie a heritable human disease
... mice that an overload of natural antioxidants can actually
lead the heart to failure. There is plenty of evidence about the damaging effects of oxidative stress, but there is another side to the coin, said Ivor Benjamin of the University of Utah, Salt Lake City. There has been so much emphasis on free radi...
Experiment suggests limitations to carbon dioxide 'tree banking'
...the Environment and Earth Sciences. "In order to actually
have an effect on the atmospheric concentration of CO2, the results suggest a future need to fertilize vast areas," Oren added. "And the impact on water quality of fertilizing large areas will be intolerable to society. Water is already a scarce reso...
High-intensity ultrasound may launch attack on cancer, wherever it lurks
...onal Institutes of Health. In most cancers, what actually
ends up killing the patient is the spread of the cancer from its original site to other parts of the body, said Pei Zhong, an associate professor in Dukes mechanical engineering and materials science department. If the patient has a tumor in the kidn...

Link identified between Alzheimer's disease and glaucoma
...pticians when they look at the back of the eye, is actually
an extension of brain tissue, travelling down the optic nerve into the back of the eye," she says. " High street opticians have been routinely looking at the brain in a more direct way than has been possible by high tech brain scanners such as MRI an...
Computer graphics spills from milk to medicine
...mputer graphics by determining how the light would actually
scatter and be absorbed. It is this information that is used to render realistic images. We have the first complete, bottom-up theoretical model that addresses the shortcoming of the Lorenz-Mie theory for participating media. It allows us to rende...
UF, French scientists seek test to detect gene doping in athletes
...iation of boosting red blood cell production is to actually
inject the EPO gene itself, which would cause increases in red blood cells, said Richard Snyder, Ph.D., an assistant professor of microbiology and molecular genetics at UF and director of UFs Center of Excellence for Regenerative Health Biotechnology...

In a first, Einstein scientists discover the dynamics of transcription in living mammalian cells
...y one percent of polymerases that bind to the gene actually
remain on to help in synthesizing an RNA molecule. Transcription is probably inefficient for a reason. Were not sure why, but it may be because all the factors needed for transcription have to come together at the right time and the right place, so t...
Discredited Korean embryonic stem cells' true origins revealed

Where broken DNA is repaired
...likely, Costes believes, that the damaged sections actually
migrate toward the less-dense chromatin and concentrate at the high-density/low-density interface. Researchers have previously proposed the existence of "repairosomes" in mammalian cells, similar to specific regions where DNA is repaired in yeast,...
Biologists at Tufts University discover 1 reason why chromosomes break, often leading to cancer

stops replication," Freudenreich said. "So when replication gets there, it has trouble, it stops, it pauses, it can't go further very easily." Most of the time, chromosomes break and heal correctly. The problem arises when they do not heal correctl...
