Researchers at The Wistar Institute have deciphered the structure of the active region of telomerase, an enzyme that plays a major role in the development of nearly all human cancers. The landmark achievement opens the door to the creation of new, broadly effective cancer drugs, as well as anti-aging therapies.
Researchers have attempted for more than a decade to find drugs that shut down telomerase - widely considered the No. 1 target for the development of new cancer treatments - but have been hampered in large part by a lack of knowledge of the enzyme's structure.

Using a novel technique, medical and engineering researchers at Stanford University have discovered a vulnerable step in the virus' reproduction process that in lab testing could be effectively targeted with an obsolete antihistamine.
The new research will be published in the Aug. 31 online version of Nature Biotechnology.

Now, a master switch has been found in the brain of mice that controls both, and researchers at the Salk Institute for Biological Studies say it may work the same way in humans.

The findings of a study by Dr Maciej Tomaszewski, New Blood Lecturer in Cardiovascular Medicine in the Department of Cardiovascular Sciences at the University of Leicester, suggest that this "male disadvantage" may be related to the sex-specific effects of naturally occurring sex hormones.
