A new study defines previously unknown properties of transmitted HIV-1, the virus that causes AIDS.
An intuitive approach, which co-opts the body’s own molecular machinery, has led to massive expansions of umbilical cord blood cells. It and other new approaches “will revolutionize all transplantation,” says University of Minnesota Blood and Marrow Transplantation Director John Wagner.
A team of researchers has generated new insight on how a stem cell’s environment influences what type of cell a stem cell will become. They have shown that whether human mesenchymal stem cells turn into fat or bone cells depends partially on how well they can “grip” the material they are growing in.
In a laboratory study pairing food chemistry and cancer biology, scientists tested the potentially harmful effect of foods and flavorings on the DNA of cells. They found that liquid smoke flavoring, black and green teas and coffee activated the highest levels of a well-known, cancer-linked gene called p53.
Engineers have developed a portable device to count white blood cells that needs less than a pinprick's worth of blood and takes just minutes to run.
Microarrays started as research tools and now often appear in clinical applications. To survey some of the hybridization systems available for this technology, we talked with experts from Agilent, SciGene, and Tecan.
Researchers have identified a humanized monoclonal antibody that targets and directly kills chronic lymphocytic leukemia (CLL) cells. The findings represent a potential new therapy for treating at least some patients with CLL, the most common type of blood cancer in the United States.
The first multi-gene test that can help predict cancer patients' responses to treatment using the latest DNA sequencing techniques has been launched in the NHS. The test detects mutations across 46 genes in cancer cells.
Under the crushing weight of many new studies finding even small head injuries can cause massive damage, the National Football League (NFL) has launched a new $60 million brain initiative. The initiative is co-sponsored by General Electric (GE).
Ever find yourself racking your brain on a Monday morning to remember where you put your car keys? When you do find those keys, you can thank the hippocampus, a brain region responsible for storing and retrieving memories of different environments- such as that room where your keys were hiding in an unusual spot.
Inflammation is stirring up headlines again. Anti-inflammatory aspirin prevented thousands more cancers. The anti-inflammatory “miracle molecule” resveratrol came back. Psychologists report inflammation is stoked by even minor tensions. And archaeologists say all this knowledge is long overdue, as even Egyptian mummies have clogged arteries. We have been plagued by inflammation since the time of the Pharaohs.
An interdisciplinary team of mechanical engineers and autism experts at Vanderbilt University have developed a system that demonstrates that robotic systems may be powerful tools for enhancing the basic social learning skills of children with autism spectrum disorder.
Researchers in Germany said Tuesday they have completed the first high-quality sequencing of a Neanderthal genome and are making it freely available online for other scientists to study. The genome produced from remains of a toe bone found in a Siberian cave is far more detailed than a previous Neanderthal genome sequenced three years ago by the same team.
Pittcon 2013 continues to showcase the release of groundbreaking products for a variety of life science applications.
To many people, spider webs are a nuisance, something that needs to be knocked down and cleared out of the way. They’re reminders that you haven’t cleaned lately. To Jeffery Yarger, spider webs, and more specifically the spider silk that makes up the webs, are structures of beauty, especially when you look at them at the microscopic level.
As Pittcon 2013 kicks off this week, companies are unveiling their latest products to the market.
Researchers have identified an elusive anti-cancer property of vitamin E that has long been presumed to exist, but difficult to find.
Researchers report that influenza virus-specific CD8+ T cells or virus-specific non-neutralizing antibodies are each relatively ineffective at conferring protective immunity alone. But, when combined, the virus-specific CD8 T cells and non-neutralizing antibodies cooperatively elicit robust protective immunity.
Despite significant advances, cancer remains one of the predominant causes of mortality in the modern world, and as such has remained a top research priority. It is a complex and continually evolving genetic disease and, as such, requires sophisticated tools for study.
A single concussion may cause lasting structural damage to the brain, according to a new study.
Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers have shown.
Over the last few months, the Nobel Prize has generated much controversy—again. More than 3,000 scientists contributed to the most high profile science event of 2012: the discovery of the Higgs boson subatomic particle. Yet the Nobel can only be split between three laureates. Was the Nobel Prize finally obsolete, the press fretted, in one angst-ridden blog after another?
A half-century quest for a holy grail of organ transplantation seemed on the verge of ending in March 2012 when a group of researchers announced some kidney transplant patients had been drug-free for more than a year. This January, they did it again.
A baby born with the AIDS virus appears to have been cured, scientists announced Sunday, describing the case of a child from Mississippi who's now 2½ and has been off medication for about a year with no signs of infection. There's no guarantee the child will remain healthy, although sophisticated testing uncovered just traces of the virus' genetic material still lingering.
“Genetic engineering is moving faster than anything we have ever seen.” With these words, Harvard University genomics pioneer George Church captured the excitement of many talks at the annual meeting of the American Association for the Advancement of Science (AAAS).
