Jun 14, 2013 — Though the regulation proposed by the Fish and Wildlife Service would make it more difficult to use chimpanzees for research purposes, that may not be a problem, some scientists say. Scientific advances show the animals are less medically useful than previously thought.
Jun 14, 2013 — The U.S. Supreme Court ruled this week that the mere act of isolating a DNA sequence does not make human genes patentable. Mary-Claire King, who helped discover the breast cancer gene at the center of the court dispute, discusses the ruling and its implications for genetics.
Jun 14, 2013 — The human brain contains some 100 billion neurons, which together form a network of Internet-like complexity. Christof Koch, chief scientific officer of the Allen Institute for Brain Science, calls the brain "the most complex object in the known universe," and he's mapping its connections in hopes of discovering the origins of consciousness.
Jun 14, 2013 — An extract from raw, green coffee beans has been called a "miracle" weight-loss aid. But a study in mice casts doubt on the supplement's fat-burning effects — and even offers preliminary evidence that it could be harmful.
Jun 14, 2013 — Looking for clues to to modern-day leprosy, scientists dig up a 500-year-old mass grave and scan for ancient strains of bacteria in human remains. They find that the bacteria that cause leprosy haven't changed, humans have.
Jun 13, 2013 — The court said biotech company Myriad could not patent human genes, since they already "existed in nature." But when it comes to synthetic DNA, the court said patents may be acceptable in some cases.
Jun 13, 2013 — Birds flock. Insects swarm. Fish swim in schools. These are all examples of collective behavior, a concept that has fascinated scientists for decades. For a recent piece in Wired Magazine, science writer Ed Yong explains what this research could tell us about predicting the future.
Jun 13, 2013 — Needle sharing and drug use put an estimated 4,000 people at risk for contracting HIV every year. Now, the same medications that are used to treat HIV-positive individuals might also protect the uninfected before they engage in risky behavior.
