Combined antiviral and targeted chemotherapyA discovery by a team of Canadian and American scientists could provide new ways to fight HIV-AIDS. As per a newly released study published in Nature Medicine, HIV-AIDS could be treated through a combination of targeted chemotherapy and current Highly Active Retroviral (HAART) therapys. This radical new treatment would make it possible to destroy both the viruses circulating in the body as well as those playing hide-and-seek in immune system........Go to the Infectious disease blog (Added on 6/21/2009 8:44:54 PM)
How obesity increases the risk for diabetesObesity is probably the most important factor in the development of insulin resistance, but science's understanding of the chain of events is still spotty. Now, scientists at the Salk Institute for Biological Studies have filled in the gap and identified the missing link between the two. Their findings, to be reported in the June 21, 2009 advance online edition of the journal Nature, explain how obesity sets the stage for diabetes and why thin........Go to the Weight watcher's blog (Added on 6/21/2009 8:42:56 PM)
RNA snippet suppresses spread of aggressive breast cancerA low cellular level of a tiny fragment of RNA appears to increase the spread of breast cancer in mouse models of the disease, as per scientists at Whitehead Institute for Biomedical Research.
Measuring levels of this so-called microRNA, which is also linked to metastatic breast cancer in humans, may more accurately predict the likelihood of metastasis (which accounts for 90% of cancer-related deaths) and ultimately help determine patient........Go to the Breast-cancer-blog (Added on 6/16/2009 5:03:17 AM)
Why do we choose our mates?Charles Darwin wrote about it 150 years ago: animals don't pick their mates by pure chance it's a process that is deliberate and involves numerous factors. After decades of examining his work, experts agree that he pretty much scored a scientific bullseye, but a very big question is, "What have we learned since then?" asks a Texas A&M University biologist who has studied Darwin's theories.
