Travellers and night shift workers should save their money and look elsewhere for help to fall asleep.
The U.S. Department of Health and Human Services released information today about research on melatonin supplements. The research was conducted at the University of Alberta for the U.S. National Center for Complementary and Alternative medicine. U of A researchers did a comprehensive review of all studies on the use of melatonin supplements to treat sleep disorders. Some of the h
Atmospheric scientists have developed simple, physics-based equations that address some of the limitations of current methods for representing cloud formation in global climate models – important because of increased aerosol pollution that gives clouds more cooling power and affects precipitation.
These researchers – led by the Georgia Institute of Technology — have also developed a new instrument for measuring the conditions and time needed for a particle to become a cloud drop
Exposure to low levels of hydrogen sulfide and possibly other airborne chemicals from nearby asphalt plants may have contributed to an increased suicide rate in a North Carolina community, a study suggests for the first time.
In 2003, the suicide rate in two Salisbury, N.C., neighborhoods was found to be 192 per 100,000 individuals a year, roughly 16 times the statewide average, as stated in community reports confirmed by death certificates for that year by the Blue Ridge Environmental De
Because up to 75 percent of breast cancer patients have an abnormality in a specific cell signaling pathway, drugs that target different molecules along that pathway may be especially effective for treating the disease, says a researcher from The University of Texas M. D. Anderson Cancer Center.
A clearer picture is now emerging about the importance of the phosphatidylinositol 3 kinase (PI3K) pathway to breast cancer development, says Gordon Mills, M.D., Ph.D., a professor and c
Transplant recipients have 96 percent survival rate after first year
Transplant researchers at the University of Pittsburgh’s Thomas E. Starzl Transplantation Institute have dramatically improved intestinal transplant graft survival, and reduced rejection and infection rates by successfully using a novel immunosuppression minimization protocol, thus improving patients’ overall quality of life and avoiding the use of several anti-rejection drugs, which can cause serious in
Despite the common belief in the oncology community that cancer research and treatment have focused on breast tumors that are estrogen receptor (ER)-positive, a researcher from The University of Texas M. D. Anderson Cancer Center maintains that clinicians have made “enormous strides” in treating patients with tumors that are ER-negative.
In a presentation at the annual meeting of the San Antonio Breast Cancer Symposium, Donald Berry, Ph.D., a professor and chair of the Depart
Men are more likely to want to marry women who are their assistants at work rather than their colleagues or bosses, a University of Michigan study finds.
The study, published in the current issue of Evolution and Human Behavior, highlights the importance of relational dominance in mate selection and discusses the evolutionary utility of male concerns about mating with dominant females. “These findings provide empirical support for the widespread belief that powerful women are at a
In a project that will likely be watched by football players, runners and other athletes, researchers at MIT and Harvard Medical School say they are developing an injectable gel that could speed repair of torn cartilage, a common sports injury, and may help injured athletes return to competition sooner. The technique uses the patient’s own cartilage-producing cells and has the potential to be more effective and less invasive than conventional cartilage repair techniques, which may include extens
Genetics, genomics, bioinformatics and neuroscience join forces
Children’s Hospital Boston has begun enrolling patients as part of an ambitious new multidisciplinary study of autism that will attempt to pin down its genetic and biochemical causes. Results could be available in a year or two, and could yield a greater biological understanding of autistic spectrum disorders, better diagnostic and prognostic techniques, and potential medical treatments.

If one of your New Year’s resolutions is to start a fitness regimen, you might want to seek professional help. A study by McMaster University’s Department of Kinesiology has found that people who are new to an exercise activity perform better when their goals are set by a fitness professional rather than by themselves.
In a study at McMaster University, exercisers were asked to perform a grip-strength task. After their first attempt, half of the participants set their own goal for the s
A group of researchers from the Department of Computer Languages and Systems at the Universitat Jaume I is taking part in a project to improve realism in video games. The goal is to design software that makes the task of game programmers easier so that they can create more credible environments without having to carry out complex operations. The research, which has received financial help of 1,649,000 euros from the European Commission and is to last for 33 months, involves 11 other members from
Secrets that zip across offices through wireless computing networks all too easily also zip through office windows into the hands of competitors – now researchers at the University of Warwick have devised a method of producing tunable surfaces that can selectively block signals from wireless networks from spilling out of the office.
Dr Christos Mias, in the University of Warwick’s School of Engineering has developed a “dipole grid based frequency–selective surface” (also known as an F
When it comes to protecting America’s combat troops in battle, research under way at the Florida A&M University-Florida State University College of Engineering could be a lifesaver.
Under a partnership with Armor Holdings, Inc. of Jacksonville, FSU researchers are developing and testing first-of-its-kind body armor for soldiers’ arms and legs that could reduce fatalities and loss of limbs when they are wounded.

Immunitor USA Inc., announces that its licensed vaccine candidate V-1 Immunitor (V1) has shown promising results in Phase II, placebo-controlled, clinical trial involving 47 HIV-infected individuals (http://www.emediawire.com/releases/2004/12/emw186195.htm)
The study was published in the special December issue of the Journal of Clinical Virology – the official journal of The Pan American Society for Clinical Virology and The European Society for Clinical Virology. The abstract o
Some researchers have doubts that mammoths lived in the cold climate zones. Recently, Russian scientists have received strong evidence of woolly mammoths’ frost-resistance – they possessed sebaceous glands. The trip to visit mammoths was paid by the International Scientific and Technical Center, and the researchers’ search for sebaceous glands was supported by the Federal Target Scientific and Technical Program entitled “Investigations and Developments for Science and Engineering Priority Guid
People quickly get used to good things. The person who has experienced joy of victory many times would wish to feel it over and over again and (s)he turns into aggressor. This has been proved by Russian researchers investigating aggressive behavior of mice.
