Neanderhals became extinct about 40,000 years ago but contributed on average one to three percent to the genomes of present-day Eurasians. Researchers have now analyzed DNA from a 37,000 to 42,000-year-old human mandible from Oase Cave in Romania and have found that six to nine percent of this person's genome came from Neanderthals, more than any other human sequenced to date. 

Because large segments of this individual's chromosomes are of Neanderthal origin, a Neanderthal was among his ancestors as recently as four to six generations back in his family tree. This shows that some of the first modern humans that came to Europe mixed with the local Neanderthals.

The environmental movement has been successful, according to humanities scholars at Michigan State University. Certainly that is where the money is. Though environmental groups and pro-science groups are industry and politically funded, only the pro-science groups are dismisses as industry-funded, despite that fact that one group, Union of Concerned Scientists, has more funding than all pro science groups in America combined. 

Researchers have developed a functioning organic solar cell consisting of a single component has been produced on the basis of metal-organic framework compounds (MOFs). The material is highly elastic and might also be used for the flexible coating of clothes and deformable components. 

Metal-organic frameworks, briefly called MOFs, consist of two basic elements, metal node points and organic molecules, which are assembled to form microporous, crystalline materials. For about a decade, MOFs have been attracting considerable interest of researchers, because their functionality can be adjusted by varying the components.

Two new studies led by UC Irvine using data from NASA Gravity Recovery and Climate Experiment satellites show that civilization is rapidly draining some of its largest groundwater basins, yet there is little to no accurate data about how much water remains in them.

The result is that significant segments of Earth's population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings appear today in Water Resources Research.

The words 'yes' and 'no' may seem like two of the easiest expressions to understand in any language, but their actual behavior and interpretation are surprisingly difficult to pin down. In a paper published earlier today in the journal Language, two linguists examine the workings of 'yes' and 'no' and show that understanding them leads to new insights concerning the understanding of questions and statements more generally.

Mortality from coronary heart disease declined in Sweden from 1986 to 2002. The improvement was due mainly to a reduction in risk factors among the healthy population (primary prevention) and, to a lesser extent, treatment of people who already had developed heart disease (secondary prevention). A study conducted at Sahlgrenska Academy explored the reasons for the trend.

Deaths from coronary heart disease fell by 53% among men and 52% among women in 1986-2002. The improvement was evident among all age groups.
