Rubén Martínez, a graduate in Biology and Biochemistry at Elhuyar Fundazioa, and colleagues have developed a new methodology that makes it possible to know what physiological state the yeast is in at each point in the wine fermentation process. 

This knowledge is of particular interest for producers, since changes in the grape directly affect the chemical composition of the must.

Some of the carbon, like the black soot and charcoal residue of fires, that finds its way into Earth's oceans stays there for thousands for years, and some of the black carbon breaks away and hitches a ride to the ocean floor on passing particles.

Virtually all black carbon results from combustion. Soot, the airborne version of black carbon, is a key element of smoke. Charcoal is another form of black carbon. Each form is produced naturally by wildfires, as well by industry and other human activities.

Research that  evaluated whether the drug cetuximab and chemotherapy together worked better than chemotherapy alone as a treatment in addition to surgery for people with bowel cancer that had spread to the liver but could be surgically removed, found it is not effective in some settings, and indeed may result in more rapid cancer progression.

The New EPOC study in The Lancet Oncology details that the trial patients either received chemotherapy on its own or chemotherapy combined with cetuximab. Patients received their specified treatment for 12 weeks. They then had surgery and followed by their specified treatment for another 12 weeks. Patients were then monitored via CT or MRI scans.

Want to turn a liberal into a conservative? Present the prospect of a racial minority becoming the overall majority in the United States, according to an analysis of Pew Research data.

White Americans across the spectrum move more toward the conservative end of the political spectrum, according to a paper in Psychological Science which suggests that increased diversity in the United States could actually lead to a wider partisan divide. Of course, it depends on the minority. Legal immigrant minorities are overwhelmingly more conservative already.

A new study published in the Proceedings of the National Academy of Sciences by scientists at the University of Queensland, Australia, overturns a long-held theory in plant science [see:http://www.bnl.gov/newsroom/news.php?a=11631]. Researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory who are co-authors on this paper conducted critical radiotracer studies that support the new theory that plant sugars play a dominant role in regulating branching at plant stems. While branching has relevance in agriculture, it is also very important in bioenergy crop production.

A new study suggests that early humans living thousands of years before Neanderthals, were able to work together in groups to hunt and slaughter animals as large as the prehistoric elephant.

University of Southampton archaeologist Dr. Francis Wenban-Smith discovered a site containing remains of an extinct straight-tusked elephant (Palaeoloxodon antiquus) in 2003, in an area of land at Ebbsfleet in Kent, during the construction of the High Speed 1 rail link from the Channel Tunnel to London. Investigation of the area was carried out with independent heritage organization Oxford Archaeology, with the support of HS1 Ltd.
