Chemists create 'Superbowl' molecule; May lead to better health

...romise for precision drug delivery, according to a recent study in the Journal of the American Chemical Society. Shaped like a miniature football stadium, the molecule is capable of delivering a wide range of drugs ?from painkillers to chemotherapy cocktails ?to specific areas of the body, potentially resul...

Association of herpesvirus with lung disorder questioned

Contrary to the results of a recent U.S. study, investigators in Japan found no association between a herpesvirus infection and a potentially life-threatening form of high blood pressure, as reported in the March 1 issue of The Journal of Infectious Diseases, now available online. The...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...Detailing the first systematic study of relatively recent horizontal gene transfer into a protist, scientists report evidence in the DNA sequence that E. histolytica likely picked up a significant number of its metabolic genes from bacterial co-inhabitants of the human gut. Identification of these genes she...

Her recent findings onhow to mass produce multiple genes on a single chip are described in apaper titled “Accurate multiplex gene synthesis from programmable DNAmicrochips,?appearing in the current issue of Nature, the weeklyscientific journal for biological an...

Study Links Ebola Outbreaks To Animal Carcasses

All recent Ebola virus outbreaks in humans in forests between Gabon and the Republic of Congo were the result of handling infected wild animal carcasses, according to a study by the Wildlife Conservation Society (WCS) and its regional partners. Appearing in the...

New Technique for Tracking Gene Regulators

...ts, but all so far have limits.For example, in one recent technique, scientists mix the regulatorprotein of interest (let’s say, CREB) with the entire genome of a celland let it bind. Then they fragment the genome into smaller pieces, 500to 1,500 nucleotide bases long. Using antibodies that specificallyreco...

Bacteria collection sheds light on urinary tract infections

...ter. Riley and DebRoy reported their findings in a recent issue of Clinical Infectious Diseases. About 8 to 10 million people are diagnosed with urinary tract infections each year. Women are more likely to get UTIs than men because it is easier for the bacteria to reach their bladder. Fifty percent of all...

Combination therapy boosts effectiveness of telomere-directed cancer cell death

In an article published by the recent issue of PLoS Biology (Vol.3 Issue 2, 2005), scientists led by the Beijing Institute of Genomics (BIG) reported a "much improved, near-complete genome analysis of the indica and japonica subspecies of O. sativa." The fine maps of the rice genome seq...

Scientists seek answers on what activates deadly anthrax spores

...ed in 18 cases and five deaths, but also after the recent scare at two military mailroom facilities when anthrax alarms went off. The group also would like to understand another closely related bacterium, Bacillus cereus, one strain of which can produce anthrax-like symptoms. The research team includes Co...
