Database Tracks Toxic Side Effects of Pharmaceuticals

Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and an important aspect of personalized medicine is to tailor therapies to individuals to reduce the chances of adverse events. Now researchers from North Carolina State University have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.

“Environmental science actually shares a common goal with drug makers: to improve the prediction of chemical toxicity,” says Dr. Allan Peter Davis, lead author of a paper on the work and the biocuration project manager of the Comparative Toxicogenomics Database (CTD) in NC State’s Department of Biological Sciences.

New Algorithm Helps Evaluate, Rank Scientific Literature

Keeping up with current scientific literature is a daunting task, considering that hundreds to thousands of papers are published each day. Now researchers from North Carolina State University have developed a computer program to help them evaluate and rank scientific articles in their field.

The researchers use a text-mining algorithm to prioritize research papers to read and include in their Comparative Toxicogenomics Database (CTD), a public database that manually curates and codes data from the scientific literature describing how environmental chemicals interact with genes to affect human health.

Revealing the Secrets of Motility in Archaea

Scientists from Berkeley Lab and the Max Planck Institute for Terrestrial Microbiology analyze a unique microbial motor

The protein structure of the motor that propels archaea has been characterized for the first time by a team of scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Germany’s Max Planck Institute (MPI) for Terrestrial Microbiology.

The motility structure of this third domain of life has long been called a flagellum, a whip-like filament that, like the well-studied bacterial flagellum, rotates like a propeller. But although the archaeal structure has a similar function, it is so profoundly different in structure, genetics, and evolution that the researchers argue it deserves its own name: archaellum.

WHOI Scientists Analyze, Explain the Chemical Makeup of Gulf Plume

Taking another major step in sleuthing the 2010 Deepwater Horizon oil spill, a research team led by the Woods Hole Oceanographic Institution (WHOI) has determined what chemicals were contained in a deep, hydrocarbon-containing plume at least 22 miles long that WHOI scientists mapped and sampled last summer in the Gulf of Mexico, a residue of the Deepwater Horizon oil spill. Moreover, they have taken a big step in explaining why some chemicals, but not others, made their way into the plume.

The findings, published this week in the online edition of the Proceedings of the National Academy of Sciences, “help explain and shed light on the plume formation and verify much of what we thought about the plume’s composition,” said WHOI chemist Christopher Reddy, lead author of the study. The data “provide compelling evidence” that the oil component of the plume sampled in June 2010 essentially comprised benzene, toluene, ethybenzene, and total xylenes—together, called BTEX—at concentrations of about 70 micrograms per liter, the researchers reported.

Expedition to Mid-Cayman Rise Identifies Unusual Variety of Deep Sea Vents

*Method included first use of Nereus hybrid vehicle in ‘autonomous’ mode*

The first expedition to search for deep-sea hydrothermal vents along the Mid-Cayman Rise has turned up three distinct types of hydrothermal venting, reports an interdisciplinary team led by Woods Hole Oceanographic Institution (WHOI) in this week’s Proceedings of the National Academy of Sciences.
