Obesity: Reviving the promise of leptin
The discovery more than a decade ago of leptin, an appetite-suppressing hormone secreted by fat tissue, generated headlines and great hopes for an effective treatment for obesity.   view more (2009-01-07)

Study Yields Clues About the Evolution of Epilepsy
Two children have a seizure. One child never has another seizure. Twenty years later, the other child has a series of seizures and is diagnosed with epilepsy. A study being led by researchers at Rensselaer Polytechnic Institute is looking at what could possibly happen in the development of these... view more (2009-01-07)

NYU scientists discover dangerous new method for bacterial toxin transfer
Scientists have discovered a new way for bacteria to transfer toxic genes to unrelated bacterial species, a finding that raises the unsettling possibility that bacterial swapping of toxins and other disease-aiding factors may be more common than previously imagined.   view more (2009-01-07)

Describing Soils: Calibration Tool for Teaching Soil Rupture Resistance
A new calibration tool was recently developed to help students and soil scientists calibrate their thumb and forefinger for the correct amount of pressure.   view more (2009-01-06)

Prolonged nevirapine in breast-fed babies prevents HIV infection but leads to drug-resistant HIV
Babies born to HIV-positive mothers and given the antiretroviral drug nevirapine through the first six weeks of life to prevent infection via breast-feeding are at high risk for developing drug-resistant HIV if they get infected anyway, a team of researchers report.   view more (2009-01-06)

Fewer deaths with preventive antibiotic use
Administering antibiotics as a preventive measure to patients in intensive care units (ICUs) increases their chances of survival. This has emerged from a study involving nearly sixthousand Dutch patients in thirteen hospitals.   view more (2009-01-05)

Blocking the spread of antibiotic resistance in bacteria
It's as simple as A, T, G, C. Northwestern University scientists have exploited the Watson-Crick base pairing of DNA to provide a defensive tool that could be used to fight the spread of antibiotic resistance in bacteria -- one of the world's most pressing public health problems.   view more (2008-12-19)

Not Just for Depression Anymore
Prozac is regularly prescribed to ease the emotional pain of patients who are being treated for cancer. But can this common anti-depressant help to fight cancer itself?   view more (2008-12-19)

First experimental evidence for speedy adaptation to pesticides by worm species
Scientists at the Instituto Gulbenkian de Ciencia (IGC) and the Faculty of Science of the University of Lisbon, in Portugal, have shown that populations of the worm Caenhorabditis elegans become resistance to pesticides in 20 generations, that is, in only 80 days.    view more (2008-12-18)

Scientists fool bacteria into killing themselves to survive
Like firemen fighting fire with fire, researchers at the University of Illinois and the University of Massachusetts at Amherst have found a way to fool a bacteria's evolutionary machinery into programming its own death.   view more (2008-12-17)

MU Researcher Refining Synthetic Molecules to Prevent HIV Resistance
Evolving HIV viral strains and the adverse side effects associated with long-term exposure to current treatments propel scientists to continue exploring alternative HIV treatments.   view more (2008-12-17)

Charting HIV's rapidly changing journey in the body
HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person's cells.   view more (2008-12-12)

Use weights, not aerobics, to ease back pain
People who use weight training to ease their lower back pain are better off than those who choose other forms of exercise such as jogging, according to a University of Alberta study.   view more (2008-12-12)

New polymer coatings prevent corrosion, even when scratched
Imagine tiny cracks in your patio table healing by themselves, or the first small scratch on your new car disappearing by itself. This and more may be possible with self-healing coatings being developed at the University of Illinois.    view more (2008-12-10)

Overweight siblings of children with type 2 diabetes likely to have abnormal blood sugar levels
Overweight siblings of children with type 2 diabetes are four times more likely to have abnormal glucose levels compared to other overweight children. Because abnormal glucose levels may indicate risk for diabetes or diabetes itself, these children could benefit from screening tests and diabetes... view more (2008-12-10)

Red alert! How disease disables tomato plant's 'intruder alarm'
How a bacterium overcomes a tomato plant's defences and causes disease, by sneakily disabling the plant's intruder detection systems, is revealed in new research out today (4 December) in Current Biology.    view more (2008-12-05)

Apple or pear shape is not main culprit to heart woes - it's liver fat
For years, pear-shaped people who carry weight in the thighs and backside have been told they are at lower risk for high blood pressure and heart disease than apple-shaped people who carry fat in the abdomen. But new findings from nutrition researchers at Washington University School of Medicine in... view more (2008-12-05)

Vaccine and drug research aimed at ticks and mosquitoes to prevent disease transmission
Most successful vaccines and drugs rely on protecting humans or animals by blocking certain bacteria from growing in their systems. But, a new theory actually hopes to take stopping infectious diseases such as West Nile virus and Malaria to the next level by disabling insects from transmitting... view more (2008-12-03)

Vitamin D found to fight placental infection
In a paper available at the online site of the journal Biology of Reproduction, a team of UCLA researchers reports for the first time that vitamin D induces immune responses in placental tissues by stimulating production of the antimicrobial protein cathelicidin.   view more (2008-12-02)

Claudin 11 stops the leaks in neuronal myelin sheaths
Devaux and Gow demonstrate how a tight junction protein called claudin 11 makes the neuronal myelin sheath a snug fit.   view more (2008-12-01)

Long-term antibiotics reduce COPD exacerbations, raise questions
Long-term use of a macrolide antibiotic may reduce the frequency of exacerbations in patients with moderate to severe chronic obstructive pulmonary disease (COPD) by as much as 35 percent, according to a London-based study.   view more (2008-11-21)

Stopping germs from ganging up on humans
Keeping germs from cooperating can delay the evolution of drug resistance more effectively than killing germs one by one with traditional drugs such as antibiotics, according to new research from The University of Arizona in Tucson.   view more (2008-11-20)

OHSU Knight Cancer Institute researcher: study may result in more targeted drugs for GIST
According to Oregon Health & Science University Knight Cancer Institute researchers, there is strong evidence that patients can have varying clinical responses to medications depending on the specific makeup of their cancer.   view more (2008-11-13)

Lead-flapping objects experience less wind resistance than their trailing counterparts
It is commonly known that racing cars and bicyclists can reduce air resistance by following closely behind a leader, but researchers from New York University and Cornell University have found the opposite is true with flapping objects, such as flags.   view more (2008-11-11)

Montana State University researchers find gene that regulates mold's resistance to drugs
Montana State University scientists concerned about lethal mold infections have found a gene that regulates the mold's resistance to drugs.   view more (2008-11-07)
