An international research team led by the University at Buffalo has shown that large energy fluctuations can rile even a "relaxed" system, raising questions about how energy might travel through structures ranging from the ocean to DNA.

Mobile DNA molecules that jump from one location in the genome to another may contribute to neurological diseases and could have subtle influences on normal brain function and behavior, according to a study published October 30 in Nature .

"Today we are learning the language with which God created life." President Bill Clinton made this remark on the White House lawn on June 2000 to recognize the decoding of the first human genome . As much as anything else, rapid DNA sequencing technology created in large part by geneticist Craig Venter and his colleagues galvanized the research community into finishing the project faster than originally expected. More than 11 years later, however, gene sequencing technology has failed to deliver on its promise to revolutionize preventative medicine, and Venter is not happy about it.

The latest offering from the prizes-for-innovation organization is specifically looking at the genes of the super elderly.

DNA analysis shows that 14th Century germ is almost identical to germ that causes plaque today

PCR--the polymerase chain reaction--is a crucial tool. The DNA amplification technique is used in genome sequencing, forensics and the diagnosis of various diseases. To give researchers more genetic material to work with, a PCR instrument repeatedly heats and cools an original biological sample

Upon news of Jobs's death, entrepreneurs shared an outpouring of personal condolences, anecdotes, and inspirations via Twitter, Facebook--even the iPhone. From Mark Zuckerberg to Jack Welch, we showcase them here.

Machine can analyze DNA samples in three minutes

Researchers searched for intelligence-associated DNA mutations and found older dads passed them through sperm

By Alison Abbott of Nature magazine The health-research division of the European Commission launches its largest-ever project next week with a €30-million (US$41-million) investment in understanding the human epigenome, the constellation of DNA modifications that shape how genes are expressed. With the project, called BLUEPRINT, Europe intends to become a major player in the International Human Epigenome Consortium (IHEC), set up last year to help biologists understand how the epigenome influences health and disease

How Terra Nova executive producer Brannon Braga realized Steven Spielberg’s vision, managed the most expensive TV budget ever, and survived all those friggin’ dinosaurs without losing his mind. Being in charge of an epic, Steven Spielberg-backed, eco-themed, sci-fi time-travel tale with digital dinosaurs and a reported $15 million pilot is pressure enough. Now add a revolving door of writers, mounting executive producers, debate over pilot length, rain-deluged sets in an Australian rainforest, insufficient footage, visual effects delays, and a circling vulture press and it’s amazing Terra Nova executive producer Brannon Braga wasn’t carried off in a straightjacket.

New techniques in DNA retrieval from dead animals might change the balance in the often fruitless quest to stop the poaching of endangered species.
