AIDS Interferes With Stem Cells In The Brain
Scientists have discovered how HIV/AIDS disrupts the normal replication of stem cells in the adult brain, preventing new nerve cells from forming. Researchers uncovered a novel molecular mechanism that inhibits stem cell proliferation and that could possibly be triggered in other neurodegenerative diseases. This discovery links mechanism for HIV/AIDS dementia, possibly other neurological disorders, with known cancer 'checkpoint'pathway. World Leaders Need To Remain Alert To Latest Scientific Thought On Cli
Melting icecaps and 'climate chaos'have put climate change at the top of the agenda for the UN General Assembly's current meeting. The report notes that while there is a general consensus on the underlying causes of the changes in our atmosphere, there is not unanimity. World leaders have been influenced by one very important document that drew its conclusions after wide consultation in the international science community, the IPCC Summary for Policymakers of the Scientific Assessment. Much of the IPCC report was compiled from extensive use of computer modelling systems which, governed by the laws of physics, have produced some very compelling theories on how and why the climate is changing.

Interventional cardiologists are investigating whether a heart procedure may be the key to relieving migraines in patients with severe headaches. Earlier studies have indicated that there may be a link between a particular congenital heart anomaly, a patent foramen ovale, and migraine. Glucose Levels Trigger Compensation For Type 2 Diabetics
Many individuals with type 2 diabetes are diabetic because their body no longer responds to the hormone insulin. Before they become clinically diabetic their body tries to compensate for the lack of insulin responsiveness by increasing the mass of insulin-secreting cells (beta cells) in the pancreas. A new study shows that in mice with high-fat diet--induced insulin resistance, changes in glucose concentration are likely to be the main trigger of increased beta-cell mass. Revised Classification System Is Effective For Predicting Breast Cance
