How Nature Makes MedicineAfter years of wondering how organisms managed to create self-medications, such as anti-fungal agents, chemists have discovered the surprisingly simple secret by shining x-ray light on the problem. MIT and Harvard researchers used crystallography beam lines at the Stanford Synchrotron Radiation Laboratory and the Advanced Light Source in Berkeley for their research.
They discovered the physical structure for an enzyme that coaxes a reaction out of stubborn chemical
concoctions to generate a large family of medically valuable compounds called halogenated natural products. The products include antibiotics, anti-tumor agents and fungicides, and they are challenging to make in a laboratory. The secret is simply a matter of the size of one of the enzyme’s parts.

The Bird has FlownThe great horned owlet that fell to the ground from End Station B in April was successfully released into the wild Saturday night from SLAC grounds. (See original SLAC Today story here.) The chick was part of a brood that nested on a high ledge in February. The owlet was not injured, but could not return to the nest. Normally the parents would fly down and feed a dislocated nestling, but timing coincided with demolition of the Final Focus Test Beam facility and the scaled-up industrial activity blocked the owlet from finding suitable shelter out of the nest. Wildlife Rescue took the owlet on April 16, where it spent two months in rehab with two adult males acting as surrogate parents. In early June it was moved to a larger cage until it demonstrated that it could catch wild mice. Read more... |
