• Barcodes to identify gene regulators

  06-09-2016 23:00
  
  The same DNA is present in every cell of an organism, but only some genes are expressed in a given cell. These genes are activated by proteins called transcription factors, in response to various biological signals. Transcription factors thus regulate most of the cellular processes, both in health and disease. A group of biologists from the University of Geneva (UNIGE), Switzerland, has developed a novel technology to identify all the transcription factors involved in any process and in response

• Bad seeds: How the parental lineage may determine viability in tomato hybrids

  06-09-2016 23:00
  
  Hybrid seeds have dramatically boosted yield for industrial scale crops such as corn, alfalfa and wheat. But for backyard tomato growers, sometimes the fruits of their labor can lie fallow as interbreeding among species of wild tomatoes often yields unviable seeds.

• New sensor could help fight deadly bacterial infections

  06-09-2016 21:25
  
  Scientists have built a new sensor that can detect the potentially deadly E.coli bacteria in 15-20 minutes, much faster than traditional lab tests. E.coli can be transmitted in contaminated food and water, posing particular risks to children and the elderly. In the late spring of 2011 a serious outbreak of E.coli bacteria sickened thousands of people in Germany and killed more than 50.

• LSU physicists collaborate on T2K CP violation results to explain workings of universe

  06-09-2016 21:14
  
  Why the universe is dominated by matter today, instead of being comprised of equal parts matter and antimatter, is one of the most intriguing questions in all of science. One of the conditions required for the observed dominance of matter over antimatter to develop is the violation of Charge-Parity (CP) symmetry, which is the principle that the laws of physics should be the same if viewed upside-down in a mirror, with all matter exchanged with antimatter. If CP violation occurs in neutrinos, it
