PITTSBURGH, June 23, 2016 - Potent doses of broccoli sprout extract activate a "detoxification" gene and may help prevent cancer recurrence in survivors of head and neck cancer, according to a trial by the University of Pittsburgh Cancer Institute, partner with UPMC CancerCenter, confirming preliminary results presented last year at the American Association for Cancer Research Annual Meeting.

It is the first study demonstrating that the extract protects against oral cancer, with the results of human, animal and laboratory tests reported today in the journal Cancer Prevention Research. This research is funded through Pitt's Specialized Program of Research Excellence grant in head and neck cancer from the National Cancer Institute.

Future global warming will not only depend on the amount of emissions from man-made greenhouse gasses, but will also depend on the sensitivity of the climate system and response to feedback mechanisms. By reconstructing past global warming and the carbon cycle on Earth 56 million years ago, researchers from the Niels Bohr Institute among others have used computer modelling to estimate the potential perspective for future global warming, which could be even warmer than previously thought. The results are published in the scientific journal, Geophysical Research Letters.

DURHAM, N.C. -- By combining super-fine electrodes and tiny amounts of a very specific drug, Duke University researchers have singled out a circuit in mouse brains and taken control of it to dial an animal's mood up and down.

Stress-susceptible animals that behaved as if they were depressed or anxious were restored to relatively normal behavior by tweaking the system, according to a study appearing in the July 20 issue of Neuron.

• Neurons are the basic information processing structures in the brain and consist of three parts: dendrites, responsible for receiving information; axons, responsible for sending information; and the soma, the cell body that contains the nucleus.

LA JOLLA, CA - June 23, 2016 - A team of scientists at The Scripps Research Institute (TSRI), University of California, San Diego (UC San Diego) and Illumina, Inc., has completed the first large-scale assessment of single neuronal "transcriptomes." Their research reveals a surprising diversity in the molecules that human brain cells use in transcribing genetic information from DNA to RNA and producing proteins.

The researchers accomplished this feat by isolating and analyzing single-neuronal nuclei from the human brain, allowing classification of 16 neuronal subtypes in the brain's cerebral cortex, the "gray matter" involved in thought, cognition and many other functions.

Finding out which is the highest mountain in the US Arctic may be the last thing on your mind, unless you are an explorer who skis from the tallest peaks around the globe. Ski mountaineer Kit DesLauriers joined forces with glaciologist Matt Nolan to settle a debate of more than 50 years, while testing a new, affordable mapping technique in a steep mountainous region. Their research is published today (23 June) in The Cryosphere, an open access journal of the European Geosciences Union (EGU).
