A US scientist has discovered an internal body clock based on DNA that measures the biological age of our tissues and organs.
The clock shows that while many healthy tissues age at the same rate as the body as a whole, some of them age much faster or slower. The age of diseased organs varied hugely, with some many tens of years "older" than healthy tissue in the same person, according to the clock.

Global Frackdown: World protests shale gas production
Thousands of people worldwide are expected to join the Global Frackdown protest on October 19. ‘Fracktivists’ from over 20 countries will gather to demand an end to fracking and “dangerous” shale gas drillings.
Numerous events are scheduled to take place mainly across the US and Europe with some rallies already having kicked off in the UK, Romania, France and Spain.
AP CEO: Press freedom v. security a 'false choice'
Governments that try to force citizens to decide between a free press and national security create a "false choice" that weakens democracy, and journalists must fight increasing government overreach that has had a chilling effect on efforts to hold leaders accountable, the president and CEO of The Associated Press said Saturday.
Gary Pruitt told the 69th General Assembly of the Inter American Press Association that the U.S. Justice Department's secret seizure of records of thousands of telephone calls to and from AP reporters in 2012 is one of the most blatant violations of the First Amendment to the U.S. Constitution the 167-year-old news cooperative has ever encountered.
The truth about criminal jurisdiction over US troops in Afghanistan
During an Oct. 12 press conference in Kabul, U.S. Secretary of State John Kerry said that under the pending U.S.-Afghan security agreement, the United States would retain exclusive jurisdiction over its service members for any crimes they commit in Afghanistan.
Kerry unfortunately misstated U.S. law, policy and practice. What's worse, he did so at a critical juncture in the negotiations for an agreement to enable American troops to remain in Afghanistan after 2014. And he did this while standing next to Afghan President Hamid Karzai. Kerry's misstatements undermined Karzai's ability to explain and advocate for the jurisdiction provisions at an upcoming loya jirga, or political assembly.
Fracking foes in California shift focus toward local limits
- California fracking opponents, frustrated in their push for a statewide ban, are going local.
Santa Cruz County last month slapped a moratorium on the controversial oil and gas production technique. Two members of the Los Angeles City Council have introduced a proposal to do the same. And they hope surrounding cities, some of which sit atop the oil fields of the Los Angeles Basin, follow suit.
"There are probably just two or three pieces of legislation I've ever introduced where random people thank me for it everywhere I go," said Councilman Paul Koretz. "I think if we were to pass this measure, we'd be hearing from cities across the country."
After saying no to feds on Medicaid expansion, Florida may ask for more federal money
Months after Florida lawmakers rejected $51 billion from the federal government to expand Medicaid, state officials are prepared to request billions in new federal aid for a different program to improve care for the poor, uninsured and under-insured.
But this cash grab, for whatever reason, has yet to ignite a political furor.
State officials want to grow their Low Income Pool (LIP) program from $1 billion a year to possibly $3 billion a year, said Justin Senior, deputy secretary for Medicaid at the Agency for Health Care Administration. The additional money could be used to help hospitals cover charity care, provide premium support for low-income Floridians or expand current healthcare programs.
Leak in Canadian natural gas pipeline curbs oil production
The Canadian National Energy Board said it was working to respond to the rupture of a natural gas pipeline operated by TransCanada in Alberta.
The NEB said it was notified by TransCanada of a leak on its Nova natural gas pipeline Thursday. The site of the release is about 85 miles west of Fort McMurray in Alberta province.
Skull Fossil Discovery Suggests Simpler Evolutionary History
After eight years spent studying a 1.8-million-year-old skull uncovered in the republic of Georgia, scientists have made a discovery that may rewrite the evolutionary history of our human genus Homo.
It would be a simpler story with fewer ancestral species. Early, diverse fossils — those currently recognized as coming from distinct species like Homo habilis, Homo erectus and others — may actually represent variation among members of a single, evolving lineage.
Air pollution can cause cancer, says World Health Organization
Outdoor air pollution has been officially classified as carcinogenic by the cancer arm of the World Health Organisation.
The International Agency for Research on Cancer (IARC) said air pollution from traffic and industrial fumes was a definite cause of lung cancer and also linked to bladder cancer. The strong verdict from IARC, a cautious body that pronounces only when the evidence is strong, will put pressure on governments to take action.
