Physical fertility of typical Mekong delta soils (Vietnam) and land suitability assessment foralternative crops with rice cultivation
Most of the soils in the Mekong delta, Vietnam are formed and developed during the Holocene period. The first Viet people came to reclaim and exploit this plain at the beginning of the 17th century. As a result, in the middle of the 19th century, the Mekong delta had become the largest region of... view more (2002-11-27)

Antibody-based therapies effective at controlling malaria
Passive immunization through the development of fully human antibodies specific to Plasmodium falciparum may be effective at controlling the disease, report researchers led by Dr. Richard S. McIntosh from the University of Nottingham in a paper published this week in the open-access journal PLoS... view more (2007-05-18)

Effectiveness of mouse breeds that mimic Alzheimer's disease symptoms questioned
Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease (AD) may not be as effective as previously assumed.   view more (2007-08-17)

Alzheimer's disease prevention may be easier than cure
Current hypotheses suggest that it is the accumulation over time of amyloid beta peptide 1-42 (Abeta42) that triggers changes in the brain that lead to cognitive dysfunction in Alzheimer's disease.   view more (2005-12-09)

Dartmouth researchers study trends in how movies depict cigarette use
Dartmouth researchers have determined that youth-rated movies contain more images of cigarette smoking than R-rated films.   view more (2006-07-17)

Reversal of role for a viral protein associated with the development of lymphoma
A protein previously thought to merely hinder the activity of a key cellular protein linked to cancer cell death, now appears to mimic the cellular signaling of that protein; potentially leading to the development of lymphoma.   view more (2005-08-23)

Researchers map infectious hepatitis B virus
Using electron cryomicroscopy and computer image analysis, the scientists visualized two intermediate forms of the virus that exist within infected cells. In addition, they were able to determine a three-dimensional map by analysis of infectious hepatitis B virus isolated from patient blood samples.   view more (2006-06-26)

Ago2 and hematopoiesis
Argonaute 2 (Ago2) is unique among its family: It is the only one of the four mammalian Argonaute proteins that exhibits endonuclease "slicer" activity (facilitation of miRNA-guided cleavage of target mRNA).   view more (2007-07-12)

GM crops show promise for developing world
Genetically modified crops could help small-scale farmers in developing countries according to the Nuffield Council on Bioethics in The use of genetically modified crops in developing countries, a Discussion Paper published today. The Nuffield Council is inviting comments on the draft paper which... view more (2003-06-09)

Daily alcohol use causes changes in sexual behavior, new study reveals
A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition.   view more (2008-01-03)

Dressman - the ironing robot
The main objective of the Dressman robot is to dry and press shirts. On placing a damp shirt on the ironing figure, this dummy inflates with hot air in its interior, and thus puffs the shirt up, removing creases drying the garment (it has to be previously wet and undergone a spin-dry in a washing... view more (2004-05-27)

Jefferson scientists find boosting protein levels staves off heart failure
Boosting levels of a protein in the heart might help protect against the development of heart failure, particularly in those who have had heart attacks.   view more (2006-09-22)

Tillage, Rotation Impacts Peanut Crops
The increasing popularity of reduced tillage on crops has not only been an important development in combating soil erosion, but it has also been associated with increasing organic material and producing high crop yields.    view more (2008-11-11)

Royal Medals for scientific achievement
The Royal Society - the UK's independent academy for science - has announced the winners of its Royal Medals for 2002. The three winners receive the awards in recognition of their achievements in the fields of cancer research, nuclear magnetic resonance and the epidemiology of smoking and chronic... view more (2002-07-30)

Friend or foe? How the body's clot-busting system speeds up atherosclerosis
Sometimes it's hard to tell friends from foes, biologically speaking. Naturally produced in the body, urokinase plasminogen activator and plasminogen interact to break up blood clots and recruit clean-up cells to clear away debris related to inflammation. In fact, urokinase manufactured as a drug... view more (2008-10-31)

Gene that magnetically labels cells shows potential as imaging tool
Mammalian cells can produce tiny magnetic nuggets after the introduction of a single gene from bacteria, scientists have found. The gene MagA could become a valuable tool for tracking cells' movement through the body via magnetic resonance imaging (MRI), says Xiaoping Hu, PhD, professor of... view more (2008-06-04)

Penn study suggests a new type of pain reliever that may benefit the heart
Building on previous work, researchers at the University of Pennsylvania School of Medicine have found that deleting an inflammation enzyme in a mouse model of heart disease slowed the development of atherosclerosis.   view more (2006-09-13)

Anti-aging hormone reduces reactive oxygen species
Scientists recently discovered an anti-aging hormone called Klotho. Now, a new study shows that this protein acts by increasing the cell's ability to detoxify harmful reactive oxygen species.   view more (2005-11-04)

Gene breakthrough heralds better prospect for malaria solution
Scientists have made a major breakthrough in understanding the genetics of the insect parasite that is being targeted by researchers as a way of preventing the spread of malaria.   view more (2006-07-25)

Scientists identify a septic shock susceptibility gene
Septic shock often follows a bacterial infection, and is characterized by the overwhelming release of pro-inflammatory cytokines by the body's immune system.   view more (2006-11-03)

The optimal stuff
Most chaotic systems are hard to grasp. This is also true of the snarls of fibers found in filters, fabrics and insulation material that filtrate solutions, absorb noise or retain heat. Manufacturers typically approach product development by trial and error. What they expect to see as a result is... view more (2003-04-24)

For two primates, patience takes different forms, shaped by ecology
Across the animal kingdom, individuals face choices between patience and impulsivity. A classic case, confronted by all animals-humans included-is that between a small, immediate food reward and a delayed, but larger, reward.   view more (2005-10-25)

Vitamin D compounds show promise for prevention of prostate cancer
The active metabolite of vitamin D, calcitriol, and other vitamin D analogs are promising chemopreventive agents that may prevent prostate cancer.   view more (2005-11-02)

Would you like gene chips with your salad ?
The first public release of plant gene chip information is being launched at the Society for Experimental Biology conference in Swansea on Friday 12th April. Scientists from the Nottingham Arabidopsis Stock Centre (NASC), part of a multi-million pound resource network, will announce a newly... view more (2002-04-11)

Methamphetamine: Use, as well as "meth mouth," on the rise
t's cheap, addictive and can harm your smile for life. Its use is also rapidly increasing both nationally and world-wide. It is methamphetamine.
