Prenatal Exposure to Marine Toxin Causes Lasting Damage
Duke University Medical Center researchers have found that the naturally occurring marine toxin domoic acid can cause subtle but lasting cognitive damage in rats exposed to the chemical before birth.   view more (2005-09-07)

Testing your reflexes until you've had enough
Can't squeeze in another mouthful? Feeling full is all a question of reflexes, according to Leeds biomedical researcher Dr David Lewis. He hopes to open the way for new therapies to treat obesity, by looking at how, why and when our brain tells our stomach it's had enough. The basic reflexes... view more (2002-05-20)

Metabolic syndrome heightens risk for development of uric-acid kidney stones
Researchers at UT Southwestern Medical Center have found that patients suffering from the metabolic syndrome - a cluster of conditions that increases the risk for heart disease, stroke and diabetes - also have a propensity to develop highly acidic urine, which increases the risk of developing... view more (2007-09-13)

British Ecological Society Winter Meeting
Press Invitation You are invited to the UK's premier ecological event, the British Ecological Society's Winter Meeting, being held at the University of Warwick on 18-20 December 2001. Thousands of ecologists from the throughout the world will be attending the meeting, which includes more than 300... view more (2001-11-23)

Drought reduces nitrogen-fixing in legumes
In drought conditions, the capacity for retaining carbon in legume nodules is limited and this may be the reason why there is a drop in nitrogen-fixing in legumes under these conditions. This was the conclusion of Mar'­a Dolores G'Ħlvez in defending her PhD thesis at the Public University of... view more (2005-02-04)

Drug slows prostate tumor growth by keeping vitamin A active
A novel compound that blocks the breakdown of retinoic acid, derived from vitamin A, is a surprisingly effective and "promiscuous" agent in treating animal models of human prostate cancer, say investigators from the University of Maryland, Baltimore (UMB).   view more (2007-11-07)

Killing brain tumors from within: A 'Trojan horse' approach
A new method for targeting malignant brain tumors through inducing the cancerous cells to "commit suicide" has been developed by a team of researchers headed by a Hebrew University of Jerusalem professor of biochemistry.   view more (2006-10-25)

Separating uranium from plutonium
Moscow researchers have made the supercritical carbon dioxide work. Saturated with special reagents, carbon dioxide first extracts uranium from the spent nuclear fuel waste, then extracts plutonium and then flies away into the atmosphere. As a matter of fact, the spent nuclear fuel consists of... view more (2003-08-08)

Researchers outline structure of largest nonvirus particle ever crystallized
Researchers at UCLA's California NanoSystems Institute, the David Geffen School of Medicine at UCLA and the Howard Hughes Medical Institute have modeled the structure of the largest cellular particle ever crystallized, suggesting ways to engineer the particles for drug delivery.   view more (2007-11-27)

New mechanism discovered for DNA recombination and repair
A biochemistry research team led by Dr. Andrew H.-J. Wang and Dr. Ting-Fang Wang at the Institute of Biological Chemistry, Academia Sinica(IBCAS), has discovered that the RecA family recombinases function as a new type of rotary motor proteins to repair DNA damages.   view more (2007-09-12)

Salmon go veggie to save wild fish stocks
Salmon, like humans, require omega-3 fatty acids in their diet to function healthily. But as the fish farming industry expands, feeding salmon and other aquatic species with pellets containing fishmeal and oil derived from processing wild-caught marine fish is unsustainable in the long term.   view more (2006-04-04)

Killing the messenger RNA — But which one?
Tiny molecules called microRNAs, only 19 to 21 nucleotides in length, are able to effectively silence sometimes large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA, responsible for conveying the information from genes to the... view more (2007-02-23)

Discovery about obesity drug helping scientists develop new cancer treatments
Based on their surprising discovery that an obesity drug can kill cancer cells, scientists at Wake Forest University School of Medicine have made a new finding about the drug's effects and are working to design more potent cancer treatments.   view more (2007-07-09)

Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage.   view more (2007-11-07)

Database shows effects of acid rain on microorganisms in Adirondack Lakes
Prior to the federal Clean Air Act, unhindered industrial emissions were released into the air throughout the Midwestern and Eastern United States for decades. Many of those harmful chemicals came right back down to earth in the form of acid rain, a chemical concoction that includes nitric and... view more (2008-06-24)

Health: Improving the recognition of brain tumours
Researchers at the Institute of Nuclear Chemistry in Jülich have developed a short-lived, radioactive amino acid that delivers much more precise information on brain tumours and their structure than was possible in the past. By combining positron emission tomography (PET), a process that... view more (2005-05-04)

Vitamin B12 function may be diminished by excessive folate
In a study of adults aged 20 and over, researchers at Tufts University showed that homocysteine and methylmalonic acid are at much higher levels in individuals who have a combination of vitamin B12 deficiency and high blood folate levels than in individuals who are also vitamin B12 deficient but... view more (2007-12-19)

Acid suppression medication linked with increased risk of hip fracture
Use of the drugs proton pump inhibitors (PPIs) for the treatment of acid-related diseases such as gastro esophageal reflux disease (GERD) is associated with a greater risk of hip fracture.   view more (2006-12-27)

Selecting life: Scientists find new way to search for origin of life
Over the last half century, researchers have found that mineral surfaces may have played critical roles organizing, or activating, molecules that would become essential ingredients to all life-such as amino acids (the building blocks of proteins) and nucleic acids (the essence of DNA). But which of... view more (2006-11-10)

How corals adapt to day and night
Researchers have uncovered a gene in corals that responds to day/night cycles, which provides some tantalizing clues into how symbiotic corals work together with their plankton partners.   view more (2008-09-15)

Surprisingly, Chemists Find, Some Solvents Can Alter Chemical Bonds
New University at Buffalo research demonstrates that some solvents can significantly enhance certain acid-base interactions and strengthen the bonding interaction between two molecules when one is electron-deficient and one is electron-rich.   view more (2007-07-25)

Major Science Prize to Nordic Scientists
Marcus Wallenberg Prize awarded for an innovation that improves environmental performance and cost-efficiency in the pulp and paper industry. Finnish scientists Johanna Buchert, Maija Tenkanen, and Tapani Vuorinen and Swedish scientist Anita Teleman, have been awarded a major international... view more (2003-01-16)

Potassium limitation, ammonium toxicity and amino acid excretion in yeast
As a single-celled eukaryote organism, the yeast strain S. cerevisiae has some limitations in terms of how it can be used as a model for more complex multicellular eukaryotes.   view more (2006-10-17)

New UNC experiments show very weak chlorine solutions can kill noroviruses
Chlorine solutions much weaker than previously believed can still be used to kill more than 99 percent of noroviruses, the chief cause of outbreaks of gastrointestinal illness around the world, a new University of North Carolina at Chapel Hill study concludes.   view more (2005-12-20)

Hot volcanic eruptions could lead to a cooler Earth
