Green Tea May Protect Brain Cells Against Parkinson's Disease
Does the consumption of green tea, widely touted to have beneficial effects on health, also protect brain cells? Green tea polyphenols protect dopamine neurons and this effect increases with the amount consumed, according to new research. Integral Reveals New Class Of 'Supergiant' X-ray Binary Stars
ESA's Integral gamma-ray observatory has discovered a new, highly populated class of X-ray fast 'transient' binary stars, undetected in previous observations. With this discovery, Integral confirms how much it is contributing to revealing a whole hidden Universe. The new class of double star systems is characterised by a very compact object that produces highly energetic, recurrent and fast-growing X-ray outbursts, and a very luminous 'supergiant' companion. The Grass Isn't Always Greener
In a series of eight experiments, scientists found that when consumers expect to make similar choices in the future, they selectively pay attention to information that suggests that an alternative would be better. These consumers also tend to disregard information that indicates their current choice is the best possible choice. Chemical Compounds Found In Whale Blubber Are From Natural Sources, No
Chemicals found in whale blubber, and initially suspected of being from industrial sources, have turned out to be naturally occurring, raising questions about the accumulation of both natural and industrial compounds in marine life. Intensive therapy for narrowed arteries linked to fewer heart events
Intensive medical therapy, including aggressive control of blood pressure and cholesterol levels, for patients with asymptomatic plaque buildup in their carotid arteries (which supply blood to the brain) appears to be associated with reduced rates of cardiovascular events and reduced risk of microemboli (microscopic-sized blood clots) in the brain arteries, according to a new study. Warning For Women Who Binge Drink: Bladder Can Rupture
As levels of binge drinking in the UK rise, doctors report three cases of bladder rupture in women who attended hospital with lower abdominal pain. In all these cases, diuresis (increased discharge of urine) and the dulling effect of alcohol, without the relief of bladder voiding, was thought to be the cause. Breastfeeding protects women from metabolic syndrome, a diabetes and h
A new study finds that breastfeeding a child may lower a woman's risk of developing metabolic syndrome, a condition linked to heart disease and diabetes in women, by up to 86 percent. The 20-year prospective study of 704 ethnically diverse women found the protective association of breastfeeding was even stronger for women who had gestational diabetes. This is the first study to measure all components of metabolic syndrome before pregnancy and after weaning. Combating Holocaust Denial: Holocaust Deniers and Public Misinformatio
This essay discusses Holocaust denial--the belief that the Holocaust never happened--with a focus on refuting the reasons for these beliefs. Includes links to related essays on Holocaust denial, annotated website links, and a press release about the December 2006 Holocaust conference in Iran, stating that it "will serve as nothing more than an international platform for Holocaust denial."From the Holocaust Encyclopedia, U.S. Holocaust Memorial Museum. Slippery Salmonella: Proteomics Exposes An Infectious Agent Of Decepti
How Salmonella escapes detection by macrophages, turning predator cells to prey complicit in promoting infection, has seemed impossibly complicated, a needle-in-a-haystack proposition involving thousands of proteins, the building blocks that carry out cells' vital functions. Now, applying the high-volume sorting and analytical power of proteomics -- a detailed survey of microbial proteins present in the 24 hours that follow mouse-macrophage infection -- a team from Pacific Northwest National Laboratory has turned up a suspect protein. Blood Vessel-building Protein Halts Blood Vessels From Forming In Canc
A piece of the protein cellular scaffolding involved in building blood vessels during development might have the opposite effect in tumors. Cell biologists at Jefferson Medical College and the Kimmel Cancer Center of Thomas Jefferson University in Philadelphia have found that the protein fragment endorepellin blocks both skin and lung cancer tumors from progressing in animal models by preventing their ability to recruit new blood vessels, a process called angiogenesis. They showed that endorepellin has surprisingly powerful effects on halting a cancer tumor's ability to move about and spread.
