Bacteria in belly buttons, armpits, and chronic wounds

Minutes after you were born, bacteria moved in. Since then, their populations have exploded, diversified and spread—on your skin and eyes and in your mouth and gut, not to mention other places. These bacterial cells now far outnumber your own cells.

New class of drugs hold promise against aggressive forms of pancreatic cancer

Cancer Research UK-funded scientists have shown how a promising new class of drugs might be used to treat aggressive forms of pancreatic cancer, according to a study published in Nature.

Scientists discover number of unknown brain networks linked with teen drug abuse

Why do some teenagers start smoking or experimenting with drugs-while others don't? In the largest imaging study of the human brain ever conducted-involving 1,896 14-year-olds-scientists have discovered a number of previously unknown networks that go a long way toward an answer.

NCI-funded research to customize treatment for oral cancer patients

The National Cancer Institute (NCI), part of the National Institutes of Health (NIH), has awarded a two-year grant to Dr. Brian L. Schmidt, professor of oral and maxillofacial surgery at the NYU College of Dentistry, and Dr. Donna G. Albertson, professor at the UCSF Helen Diller Family Comprehensive Cancer Center. The grant will fund groundbreaking research to customize treatment for oral cancer patients.

Memory aging and brain maintenance

Aging may seem unavoidable, but that's not necessarily so when it comes to the brain. So say researchers in the April 27th issue of the Cell Press journal Trends in Cognitive Sciences explaining that it is what you do in old age that matters more when it comes to maintaining a youthful brain not what you did earlier in life.

Mirror-microRNAs control multiple aspects of brain function

Our genes control many aspects of who we are - from the colour of our hair to our vulnerability to certain diseases - but how are the genes, and consequently the proteins they make themselves controlled? Researchers have discovered a new group of molecules which control some of the fundamental processes behind memory function and may hold the key to developing new therapies for treating neurodegenerative diseases.

Glycolipids play an important role in intercellular signalling

In a new study, scientists at the University of Copenhagen show that a specific type of carbohydrate plays an important role in the intercellular signalling that controls the growth and development of the nervous system. In particular, defects in that carbohydrate may result in the uninhibited cell growth that characterizes the genetic disease neurofibromatosis and certain types of cancer.

Breast-fed babies may have healthy gut microbial population

Early colonization of the gut by microbes in infants is critical for development of their intestinal tract and in immune development. A new study, published in BioMed Central's open access journal Genome Biology, shows that differences in bacterial colonization of formula-fed and breast-fed babies leads to changes in the infant's expression of genes involved in the immune system, and in defense against pathogens.

Detrimental effect of tetracycline on male reproductive function, sperm viability of pseudoscorpions

In a paper published today in Nature's open access journal Scientific Reports, researchers at the University of Nevada, Reno report that male pseudoscorpions treated with the antibiotic tetracycline suffer significantly reduced sperm viability and pass this toxic effect on to their untreated sons. They suggest that a similar effect could occur in humans and other species.

Cedars-Sinai scientist receives ALS Association Golden West Chapter Commitment to a Cure Award

Robert H. Baloh, MD, PhD, director of Cedars-Sinai Medical Center's Neuromuscular Division, has received the ALS Association Golden West Chapter Commitment to a Cure Award.

First idiothetic memory study in humans

It's night time. The light suddenly goes out in the room where you are. At the same time you hear somebody crying: "Fire!". You bolt. Will you be able to find your way out in total darkness? Most likely, yes - if the room is somewhat familiar to you and not too big. Escape will be possible because of idiothetic memory, one of two types of human spatial memory. This type of memory relies not on visual information, but on information coming from the body. In the Nencki Institute of Experimental Biology of the Polish Academy of Sciences in Warsaw it was investigated whether this type of memory can be affected by age.

UAB researcher wins HudsonAlpha Prize for work on sickle cell and related blood disorders

Tim Townes, Ph.D., University of Alabama at Birmingham, was awarded the HudsonAlpha Prize for his work on sickle cell and related blood disorders. The $20,000 monetary award acknowledges exceptional talent, dedication and discovery by Alabama's best and brightest researchers.

Researchers use Moffitt's Total Cancer Care to create designer lymph nodes

Researchers at Moffitt Cancer Center are in the first phase of creating "designer lymph nodes." Designer lymph nodes are built with specialized gene-modified cells that are injected into patients and produce a pre-planned immunologic response for cancer patients locally and then throughout their bodies. The researchers are examining a cancer vaccine "boosting" effect of the manufactured lymph nodes in patients with advanced melanoma.

Study highlights role of cellular forces in progression of cardiovascular disease

Clogging of pipes leading to the heart is the planet's number one killer. Surgeons can act as medical plumbers to repair some blockages, but we don't fully understand how this living organ deteriorates or repairs itself over time.

Researchers discover gene for new form of intellectual disability

Researchers at the Centre for Addiction and Mental Health (CAMH) led a study discovering a gene for a new form of intellectual disability, as well as how it likely affects cognitive development by disrupting neuron functioning.

Researchers define structure of key part of human obesity receptor

Medical researchers at the University of Sheffield have defined the structure of a key part of the human obesity receptor- an essential factor in the regulation of body fat- which could help provide new treatments for the complications of obesity and anorexia.

Drug-resistant malaria might be spreading in Africa, study suggests

A strain of malaria that is resistant to artemether, the main ingredient in Coartem, a widely used drug to treat the disease, may be spreading in Africa, according to a study published Thursday in Malaria Journal, Bloomberg Businessweek reports.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Smoking during pregnancy may increase risk of autism in children

Women who smoke in pregnancy may be more likely to have a child with high-functioning autism, such as Asperger's Disorder, according to preliminary findings from a study by researchers involved in the U.S. autism surveillance program of the Centers for Disease Control and Prevention.

Kras gene triggers metabolic changes that fuel cancer cells

Researchers at Dana-Farber Cancer Institute have shown that advanced pancreatic cancers in mice can't survive without continued expression of a mutant oncogene that "rewires" key metabolic pathways to fuel the cancer cells.
