Smac-ing back at cancer cells

By mimicking a molecular switch that triggers cell death, researchers have killed cells grown in the laboratory from one of the most resilient and aggressive cancers – a virulent brain cancer known as glioblastoma. The new approach to tricking the cell-death machinery could be applied to a wide range of cancers where this pathway, known as apoptosis, has been inactivated.

The researchers — led by Xiaodong Wang, a Howard Hughes Medical Institute investigator at the University of Tex

UK scientists detect new ring and one, possibly two, objects at Saturn

The joint NASA/ESA/ASI Cassini-Huygens mission is continuing to provide a fascinating insight into the Saturn system. The latest detection of one small body, possibly two, orbiting in the planet’s contorted F ring region and a ring of new material associated with Saturn’s moon Atlas, has been made by a team of UK scientists.

A small object was discovered moving near the outside edge of the F ring, interior to the orbit of Saturn’s moon Pandora. The object was first seen by Professor C

Intellectural Property Used to Create Scientific Software to Aid in Drug Design

VeraChem LLC founders Drs. Michael Gilson, Michael Potter, and Hillary Gilson, using UMBI licensed intellectual property, are creating scientific software that provides expert users with tools for computer-aided drug discovery and molecular design. VeraChem’s recent first sale, a pre-release version of Vconf, is followed by the projected launch on September 8 of Vcharge, a new software product for computing molecular properties important in drug design. The official launch of Vconf is expected to f

Broken arms and collateral damage: clues to predator-driven evolution

Ever since Darwin’s day, scientists have been trying to understand how interactions among living creatures—competition and predation, for example—drive evolution.

Recent work by paleontologists Tomasz Baumiller of the University of Michigan and Forest Gahn of the Smithsonian’s National Museum of Natural History offers new insights into the process. A report on their research appears in today’s issue of Science.

Biologists long have speculated that preda

Identifying tick genes could halt disease, bioterrorism threat

Ticks as small as a freckle can transmit a number of illnesses for which there is no vaccine and, in some cases, no cure. These creatures even could become bioterrorism weapons.

To find new ways to control the tiny animals and halt the spread of the pathogens they carry, Purdue University researchers and colleagues from the University of Connecticut Health Center, the University of Notre Dame and Massachusetts Institute of Technology are undertaking the job of unraveling the genetic
