Mechanism promoting multiple DNA mutations described by scientists
Recent studies have shown that cancer development frequently involves the formation of multiple mutations that arise simultaneously and in close proximity to each other. These groups of clustered mutations are frequently found in regions where chromosomal rearrangements take place. The finding that cancer development often involves multiple mutations arising in clusters and in regions where chromosomal rearrangement takes place may one day lead to new cancer therapies.

New malaria vaccine candidates identified
Researchers have discovered new vaccine targets that could help in the battle against malaria. Taking a new, large-scale approach to this search, researchers tested a library of proteins from the Plasmodium falciparum parasite with antibodies produced by the immune systems of a group of infected children.

Scientists reproduce evolutionary changes by manipulating embryonic development of mice
By modifying the embryonic development of mice, scientists have reproduced in the laboratory the changes in teeth shape which, in mammals, took millions of years of evolution to take place.

Barnacles: Marine 'pest' provides advances in maritime anti-fouling and biomedicine
Biologists performed cutting-edge research on a marine pest that will pave the way for novel anti-fouling paint for ships and boats and also improve bio-adhesives for medical and industrial applications.

Soy may help women's hearts if they start early
A diet rich in soy may help feminine hearts, but timing matters, finds a new study. "This study underscores how important it is for women to get into the best cardiovascular shape they can before menopause. The healthy habits they start then will carry them through the years to come," says one expert.

Eating tree nuts results in 'modest decreases' in blood fats and sugars, survey finds
Eating tree nuts appears to help reduce two of the five markers for metabolic syndrome, a group of factors that raise the risk for heart disease and other health problems such as diabetes and strokes, a new research paper says.

Drinking sugar-sweetened beverages during adolescence impairs memory, animal study suggests
Daily consumption of beverages sweetened with high-fructose corn syrup or sucrose can impair the ability to learn and remember information, particularly when consumption occurs during adolescence, a study done in rats suggests.

Vaccine against tick-transmitted disease under development
An important advancement toward developing a vaccine against the debilitating and potentially deadly tick-transmitted disease, human granulocytic anaplasmosis has been made by scientists. Successful vaccine development hinges on knowing what to target to prevent disease, and the research team has identified three such proteins on the surface of the HGA agent.

New method provides researchers with efficient tool for tagging proteins
With a new method, researchers use a piece of DNA engineered to bind to metal ions. Using this 'control stick,' they direct another piece of DNA to a metal binding site on the protein. The new method makes it possible to direct the tagging of proteins with DNA to a particular site on the protein, without genetically modifying the protein beforehand. In other words, it is possible to tag natural proteins, including antibodies.

When it comes to gluten-free diets, unfounded beliefs abound
Lots of people are eating gluten-free diets, but perhaps for the wrong reasons, a UF/IFAS researcher says. Such diets, while necessary for those with celiac disease, may lack nutrients essential to good health.
