Nanowires can detect molecular signs of cancer, scientists find
Harvard University researchers have found that molecular markers indicating the presence of cancer in the body are readily detected in blood scanned by special arrays of silicon nanowires - even when these cancer markers constitute only one hundred-billionth of the protein present in a drop of... view more (2005-09-26)

Psychopathic behaviour linked to brain chemical imbalance
Psychopathic behaviour seems to be linked to an imbalance in critical brain chemicals, reveals a study of violent and sexual offenders, reported in the Journal of Neurology Neurosurgery and Psychiatry. The findings are based on 28 men up to the age of 45, all of whom had committed violent crimes,... view more (2003-06-18)

New technique sheds light on Alzheimer’s and CJD
Researchers using laser light fired at proteins believe they could be close to identifying the molecular architecture that predisposes certain proteins to become ‘corrupted’ and misfold, causing diseases such as Parkinson’s, Alzheimer’s and the spongiform encaphalopathies,... view more (2000-11-16)

ASGE offers guidelines on endoscopic treatment of dyspepsia
The American Society for Gastrointestinal Endoscopy (ASGE) has issued guidelines for the role of endoscopy in treating dyspepsia, discomfort thought to arise from the upper-gastrointestinal tract, which affects a fourth of the population in Western countries.   view more (2007-12-26)

UNH Scientists Continue To Fly High As NASA Unlocks The Puzzle Of Global Air Quality
The National Aeronautic and Space Administration's (NASA) DC-8 research aircraft is arguably the world's most sophisticated flying laboratory and scientists from the University of New Hampshire have been onboard the jet conducting one-of-a-kind science for the past two decades.   view more (2006-04-28)

Common anti-convulsant drug may help slow the progression of dementia
Researchers have found that a common anticonvulsant drug improved cognitive function and appeared to restore nerve cells in the brains of patients with HIV-related dementia.   view more (2006-03-14)

Healthier milk straight from the cow
British scientists have found a natural way to produce healthier milk and butter, according to new research in the Journal of the Science of Food and Agriculture. Cows fed rapeseed oil as part of their daily diet produce milk with a significantly less saturated fat. Butter made from the milk is... view more (2004-03-11)

UF scientists find sugar may have a sour side
University of Florida researchers have identified one possible reason for rising obesity rates, and it all starts with fructose, found in fruit, honey, table sugar and other sweeteners, and in many processed foods.   view more (2005-12-08)

Bacteria that cause tooth decay able to survive without important biochemical pathway
Leave it to the bacteria that cause tooth decay to be able to live without something all cells were thought to require.   view more (2005-12-14)

World's largest flower evolved from family of much tinier blooms
The plant with the world's largest flower - typically a full meter across, with a bud the size of a basketball - evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science.   view more (2007-01-12)

Antioxidants may protect against tick-borne illness
Researchers are investigating the role that antioxidants - alpha-lipoic acid and potentially others like green tea and vitamins C and E, for example - might play in preventing or treating the deadly rickettsia bacteria.   view more (2006-08-10)

Stanford researchers make first direct observation of 3-D molecule folding in real time
All the crucial proteins in our bodies must fold into complex shapes to do their jobs. These snarled molecules grip other molecules to move them around, to speed up important chemical reactions or to grab onto our genes, turning them "on" and "off" to affect which proteins our... view more (2008-02-15)

Coding for arthropods-what's so special about insects and spiders?
The central dogma of molecular biology is that DNA makes RNA makes protein. This relies on a specific underlying code which relates given triplets of RNA nucleotides into specific amino acids.   view more (2006-04-25)

Chemistry can make us greener
The way in which chemistry can make industry greener is highlighted in a new website for A-level students. The site focuses on the practical application of chemistry to make industrial processes more environmentally friendly. It gives students vital examples of real-world problems and how to solve... view more (2004-03-09)

Mayo Clinic proceedings highlights research about cardiovascular benefits of omega-3 fatty acids
Thousands of research studies have documented how the oils known as omega-3 fatty acids can benefit the cardiovascular system, particularly among people diagnosed with coronary artery disease.   view more (2008-03-11)

Common epilepsy drug could prevent and treat Alzheimer's disease
The team led by UBC Psychiatry Prof. Weihong Song, who is also the Jack Brown and Family Professor and Chair in Alzheimer's Disease at UBC, found that if Valproic Acid (VPA) is used as a treatment in early stages of AD memory deficit is reversed.   view more (2008-10-27)

Levels of folate in men's diets is linked to chromosomal abnormalities in their sperm
Researchers have found an association between a vitamin found in leafy green vegetables, fruit and pulses and levels of chromosomal abnormalities in men's sperm. Men who consumed high levels of folate (a water-soluble B vitamin that occurs naturally in food) and folic acid (the synthetic form of... view more (2008-03-20)

Leprosy, tuberculosis, and peanuts
Nitric oxide is a natural part of the body’s immune defense. Linköping University researcher Thomas Schön has studied this compound in connection with the skin disease leprosy and the lung disease tuberculosis. The Swedish researcher has found that nitric oxide probably contributes... view more (2002-11-01)

A fatty acid found in milk may help control inflammatory diseases
One of the isomers of conjugated linoleic acid, a group of fatty acids found in milk, is a natural regulator of the COX-2 protein, which plays a significant role in inflammatory disease such as arthritis and cancer.   view more (2005-10-19)

Genome sequence of lancelet shows how genes quadrupled during vertebrate evolution
The newly sequenced genome of a dainty, quill-like sea creature called a lancelet provides the best evidence yet that vertebrates evolved over the past 550 million years through a four-fold duplication of the genes of more primitive ancestors.   view more (2008-06-19)

Details of the life cycle of SARS coronavirus
A team of scientists studying Severe Acute Respiratory Syndrome (SARS) has, for the first time, described how the SARS virus manufactures several of the materials required for making copies of itself. "It is essential, when you are looking for ways to stop a disease, that you know exactly how... view more (2003-07-08)

Omega-6 fats cause prostate tumors to grow twice as fast
Omega-6 fatty acids-such as those found in corn oil-caused human prostate tumors in cell culture to grow twice as quickly as tumors to which omega-6 fats had not been added, according to a study conducted at the San Francisco VA Medical Center.   view more (2006-02-01)

Protein sensor for fatty acid buildup in mitochondria
Just as homes have smoke detectors, cells have an enzyme that responds to a buildup of fatty acids by triggering the production of a key molecule in the biochemical pathway that breaks down these fatty acids, according to investigators at St. Jude Children's Research Hospital.   view more (2007-02-15)

Improper consumption of acidic foods could lead to destroyed enamel
Fruit, yogurt, citric and soft drinks, may seem like harmless snacks and beverages, but improper consumption and overuse may lead to devastating and permanent damage to teeth.   view more (2007-06-26)

Lactic acid not athlete's poison, but an energy source-if you know how to use it
In the lore of marathoners and extreme athletes, lactic acid is poison, a waste product that builds up in the muscles and leads to muscle fatigue, reduced performance and pain.   view more (2006-04-20)
