Another reason to avoid high-fat diet -- it can disrupt our biological clock
Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms - everyone's 24-hour biological clock, Hebrew University of Jerusalem researchers have shown.   view more (2008-12-29)

How to tell if a hepatitis-C-virus-infected patient will respond to therapy
Hepatitis C virus (HCV) causes hepatitis and increased risk of developing liver cancer. Current treatments are expensive, have severe side effects, and fail in about half the patients treated.   view more (2008-12-23)

Using math to understand hep. C: Patterns paint picture of who will respond to treatment
Genetic patterns are like the tea leaves in the bottom of a cup for predicting which patients are likely to respond to medical therapy for life-threatening viruses such as hepatitis C, Saint Louis University researchers have discovered.   view more (2008-12-23)

New evidence that people make aspirin's active principle -- salicylic acid
Scientists in the United Kingdom are reporting new evidence that humans can make their own salicylic acid (SA) - the material formed when aspirin breaks down in the body.   view more (2008-12-23)

Researchers find chink in the armor of viral 'tummy bug'
Researchers at Griffith University's Institute for Glycomics in collaboration with colleagues at the University of Melbourne have moved a step closer to identifying a broad spectrum treatment for the dreaded 'viral tummy bug' or rotavirus.   view more (2008-12-23)

Researchers push nature beyond its limits to create higher-density biofuels
For the first time, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have successfully pushed nature beyond its limits by genetically modifying Escherichia coli, a bacterium often associated with food poisoning, to produce unusually long-chain alcohols essential in... view more (2008-12-19)

Earth's original ancestor was LUCA, not Adam nor Eve
Here's another argument against intelligent design. An evolutionary geneticist from the Université de Montréal, together with researchers from the French cities of Lyon and Montpellier, have published a ground-breaking study that characterizes the common ancestor of all life on earth,... view more (2008-12-18)

New Satellite Data Reveal Impact of Olympic Pollution Controls
Chinese government regulators had clearer skies and easier breathing in mind in the summer of 2008 when they temporarily shuttered some factories and banished many cars in a pre-Olympic sprint to clean up Beijing's air. And that's what they got.   view more (2008-12-17)

Hundreds of millions of people, mainly in developing countries, are disabled by infectious diseases, according to the World Health Organization.   view more (2008-12-17)

Potential breakthrough for T-Cell lymphoma patients with drug that mimics folic acid
Preliminary results of a pivotal Phase 2 clinical trial of pralatrexate (PDX), a drug that partially works by mimicking folic acid, showed a complete or partial response in 27 percent of patients with recurrent or resistant peripheral T-cell lymphoma (PTCL).   view more (2008-12-10)

Study sheds light on causes of HIV dementia
A new study led by researchers at Albert Einstein College of Medicine of Yeshiva University has clarified how two major variants of HIV differ in their ability to cause neurologic complications.   view more (2008-12-04)

Risk of death may be higher with drug commonly used during cardiac surgery
The risks of death are probably higher with aprotinin, a drug commonly used to control blood loss and transfusions during cardiac surgery.   view more (2008-12-03)

Calcium and vitamin D may not be the only protection against bone loss
Diets that are high in protein and cereal grains produce an excess of acid in the body which may increase calcium excretion and weaken bones, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).   view more (2008-12-03)

Drink brewed tea to avoid tooth erosion
Today, the average size soft drink is 20 ounces and contains 17 teaspoons of sugar. More startling is that some citric acids found in fruit drinks are more erosive than hydrochloric or sulfuric acid-which is also known as battery acid.   view more (2008-11-26)

Ocean growing more acidic faster than once thought
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide.   view more (2008-11-25)

Hairspray is linked to common genital birth defect, says study
Women who are exposed to hairspray in the workplace during pregnancy have more than double the risk of having a son with the genital birth defect hypospadias, according to a new study published today in the journal Environmental Health Perspectives.    view more (2008-11-24)

Conference report highlights new research into drug delivery to treat eye disease

'Airport malaria' -- cause for concern in the US
In a global world, significant factors affect the spread of infectious diseases, including international trade, air travel and globalized food production. "Airport malaria" is a term coined by researchers to explain the more recent spread of malaria to areas such as the United States and... view more (2008-11-12)

Scientists map steps to block key enzyme action in heart failure
Taking a cue from the way drugs like Viagra put the biological brakes on a key enzyme involved in heart failure, scientists at Johns Hopkins have mapped out a key chemical step involved in blocking the enzyme.   view more (2008-11-12)

UC Davis researchers discover Achilles' heel in pancreatic cancer

Extreme weather postpones the flowering time of plants
Extreme weather events have a greater effect on flora than previously presumed. A one-month drought postpones the time of flowering of grassland and heathland plants in Central Europe by an average of 4 days.   view more (2008-11-06)

Folic acid, B vitamins do not appear to affect cancer risk
A daily supplementation combination that included folic acid and vitamin B6 and B12 had no significant effect on the overall risk of cancer, including breast cancer, among women at high risk of cardiovascular disease, according to a study in the November 5 issue of JAMA.   view more (2008-11-05)

Is ineffective esophageal motility associated with gastropharyngeal reflux disease?
IEM is associated with an increased acid clearance times in the distal esophagus. Gastropharyngeal reflux causes supraesophageal manifestations such as globus, chronic cough, hoarseness, asthma, chronic sinusitis, or other otorhinolaryngologic diseases.   view more (2008-11-03)
