Researchers use sugar to halt esophageal cancer in its tracks

Scientists have identified changes in the patterns of sugar molecules that line pre-cancerous cells in the esophagus, a condition called Barrett’s dysplasia, making it much easier to detect and remove these cells before they develop into esophageal cancer. These findings have important implications for patients and may help to monitor their condition and prevent the development of...

Good parents are predictable -- at least when it comes to corn

In order to breed new varieties of corn with a higher yield faster than ever before, researchers at the University of Hohenheim in Stuttgart, Germany, and other institutions are relying on a trick: early selection of the most promising parent plants based on their chemical and genetic makeup, as well as on new statistical analysis procedures. The work has now been published in the authoritative...

Neural balls and strikes: Where categories live in the brain

Hundreds of times during a baseball game, the home plate umpire must instantaneously categorize a fast-moving pitch as a ball or a strike. In new research from the University of Chicago, scientists have pinpointed an area in the brain where these kinds of visual categories are encoded.

New automated imaging to greatly speed whole-brain mapping efforts

A new technology developed by neuroscientists at Cold Spring Harbor Laboratory (CSHL) transforms the way highly detailed anatomical images can be made of whole brains. Until now, means of obtaining such images – used in cutting-edge projects to map the mammalian brain -- have been painstakingly slow and available only to a handful of highly specialized research teams.

Quantitative imaging application to gut and ear cells

From tracking activities within bacteria to creating images of molecules that make up human hair, several experiments have already demonstrated the unique abilities of the revolutionary imaging technique called multi-isotope imaging mass spectometry, or MIMS, developed by researchers at Brigham and Women's Hospital (BWH). MIMS can produce high-resolution, quantitative three-dimensional images of...

Researchers find novel way to prevent drug-induced liver injury

Massachusetts General Hospital (MGH) investigators have developed a novel strategy to protect the liver from drug-induced injury and improve associated drug safety. In their report receiving advance online publication in the journal Nature Biotechnology, the team reports that inhibition of a type of cell-to-cell communication can protect against the damage caused by liver-toxic drugs such as...

Researchers use sugar to halt esophageal cancer in its tracks

Scientists working at the Medical Research Council have identified changes in the patterns of sugar molecules that line pre-cancerous cells in the esophagus, a condition called Barrett's dysplasia, making it much easier to detect and remove these cells before they develop into esophageal cancer. These findings, reported in the journal Nature Medicine, have important implications for patients and...

Phobos-Grunt Mars probe falls into Pacific Ocean

Novel way to prevent drug-induced liver injury

Investigators have developed a novel strategy to protect the liver from drug-induced injury and improve associated drug safety. The team reports that inhibiting a type of cell-to-cell communication can protect against damage caused by liver-toxic drugs such as acetaminophen.
