Scientists are reporting an advance in the science of aging and maybe even a clue how to reverse some of aging's effects. They have evidence that lifestyle changes already known to be good for you, like healthy diet, exercise, reducing stress may prevent the chromosomes in our cells from unraveling.
NPR's Richard Knox reports that it's all about little caps on our chromosomes called telomeres.
When the Affordable Care Act was working its way through Congress, Gary Lauer was nervous. Part of the bill sounded grim. It said people could buy required health coverage online, but only through websites run by state and federal governments.
"That was going to pretty much delete us from the landscape," he says.
How often do whales clean their ears? Well, never. And so, year after year, their ear wax builds up, layer upon layer. According to a study published Monday, these columns of ear wax contain a record of chemical pollution in the oceans.
The study used the ear wax extracted from the carcass of a blue whale that washed ashore on a California beach back in 2007. Scientists at the Santa Barbara Museum of Natural History collected the wax from inside the skull of the dead whale and preserved it. The column of wax was almost a foot long.
From the standpoint of global warming, burning natural gas can be better than burning coal, a study published this week suggests.
This is a contentious issue among people who are opposed to the natural gas drilling practice known as fracking. That technique involves injecting water, sand and chemicals into wells to release far more gas than conventional drilling can. Opponents of fracking have been concerned not only about local environmental issues, but also about the potential for methane leaks to make global warming worse.
A line of men in black rain boots push trash carts through the alleys of Lahore, Pakistan. They stop at an open sewer along a neighborhood street and start to pull up shoes, bricks, plates and any other trash that might block the flow of wastewater.
Standing water is a prime breeding ground for mosquitoes. And the local government in Lahore is on a focused mission: Stop the spread of dengue fever by mosquitoes.
