Under certain conditions vapor bubbles can form in fluids moving swiftly over a surface and those bubbles soon collapse with such great force that they can even poke holes in steel and damage objects such as ship propellers and fuel pumps.   

Proteins are the indispensable catalytic workhorses, carrying out the processes essential to life in today's sophisticated organisms, but long ago ribonucleic acid (RNA) reigned supreme.

Researchers have produced an atomic picture that shows how two of these very old molecules interact with each other and it provides a rare glimpse into the transition from an ancient, RNA-based world to our present, protein-catalyst dominated world. 

Want to kill about 8,000 hours of your life?   Go to data.gov and start looking around.  In the interest of transparency (well, sometimes - see Recovery Accountability and Transparency meeting not open to the public), the Obama Administration has posted over 270,000 sets of raw data from its departments, agencies, and offices on the World Wide Web.

As life expectancies increase, so does the number of elderly people undergoing surgical procedures.    Recently, there has been growing about potential neurotoxicity of anesthetics and their role in post-operative cognitive decline.

Alzheimer's Disease(AD) is a devastating disease most commonly found in elderly people. It is manifested by severe memory loss, language problems, impaired decision making and affected activities of daily living.

In vitro fertilization (IVF) has brought children to millions who otherwise had difficulty conceiving so it should be a happy time.   Yet over 20% of women who undergo IVF report symptoms of depression.

The belief has been that the common denominator in women who undergo IVF - hormone therapy - is the culprit, but new Tel Aviv University shows that other factors have a large influence in who gets depressed and why and resolving those issues will make the success of the IVF greater.
