October 11, 2013 Journal editors would usually require researchers to disclose the genetic sequences needed to make a toxin that is the subject of a scientific paper. But the requirement was waived in the case of a new botulinum toxin because of the security risk.
October 10, 2013 A lack of funding to labs is likely to mean an early death for thousands of mice used in scientific and medical research. The loss of specialty mice, many of which have genes that can cause them to develop versions of human diseases, is especially troubling to scientists — and expensive.
October 10, 2013 A study shows that genes that help our skin withstand damage from ultraviolet light kick in during the day. At night, our skin focuses instead on regenerating cells that were damaged during the day. This built-in system helps protect us from premature aging and skin cancer.
October 9, 2013 The three scientists sharing the 2013 Nobel Prize for chemistry developed computerized tools for studying complex molecules, such as enzymes and the photosynthesis machinery. These techniques allow engineers to design drugs and new chemical reactions more quickly and cheaply.
October 9, 2013 Martin Karplus, Michael Levitt and Arieh Warshel pioneered powerful technology that is now used to develop drugs and perform other vital tasks in the laboratory.
October 9, 2013 Scientists who do research in Antarctica have just learned that the shutdown will effectively cancel all of their planned fieldwork on the icy continent this year. All research activities not essential to human safety and the preservation of property will be stopped.
October 8, 2013 A decades-long effort to prevent one of the world's leading scourges has resulted in a vaccine with only modest efficacy. Still, the shot has the potential to save hundreds of thousands of lives each year. So its developers are seeking regulatory approval in 2014.
October 7, 2013 Scientists who study the remote, rugged continent at the bottom of the world are on edge as funding for research there remains in jeopardy. It hasn't been decided yet if Antarctic operations for the research season will be allowed to continue.
October 7, 2013 The tiny, cube-shaped robots, called M-Blocks, can spin and jump their way into new configurations.
October 7, 2013 The Nobel Prize in Physiology or Medicine 2013 goes to three scientists for discovering how cells secrete hormones and neurotransmitters. The research provided sweeping insights into how the brain transmits signals, the immune system attacks pathogens and insulin gets into the bloodstream.
