An international team of researchers sequenced nuclear and mitochondrial DNA that had been extracted from the leg of an early modern human from Tianyuan Cave near Beijing, China and found that the human from 40,000 years in China is related to many people on multiple continents.

Analyses of this individual's DNA showed that the Tianyuan human shared a common origin with the ancestors of many present-day Asians and Native Americans. In addition, the researchers found that the proportion of Neanderthal and Denisovan-DNA in this early modern human is not higher than in people living in this region nowadays.


Researchers have announced the discovery of a two million year old fossil fox at the now renowned archaeological site of Malapa in the Cradle of Humankind World Heritage Site.
 

The previously unknown species of fox is named Vulpes Skinneri, for the recently deceased South African mammalogist and ecologist Prof. John Skinner of the University of Pretoria.
 


In Europe, where over 19 million students are in tertiary education, they are looking for ways to improve the teaching skills of scientists in order to teach more effectively the next generation of innovators.  It would seem obvious that reducing the anti-science mentality of the culture would be the obvious step but the sociologists argue instead that the position of 'teacher researcher' should be created under the social sciences banner.


Rats socially isolated during a critical period in adolescence are more vulnerable to addiction to amphetamine and alcohol, according to a new paper. Amphetamine addiction is also harder to extinguish in the socially isolated rats.

These effects persist even after the rats are reintroduced into the community of other rats.

"Basically the animals become more manipulatable," said Hitoshi Morikawa, associate professor of neurobiology in the College of Natural Sciences. "They're more sensitive to reward, and once conditioned the conditioning takes longer to extinguish. We've been able to observe this at both the behavioral and neuronal level."


In a genome-wide analysis of 13 metastatic prostate cancers done on men who died of metastatic prostate cancer and whose tissue samples were collected after a rapid autopsy, scientists found consistent epigenetic signatures across all metastatic tumors in each patient. 

The discovery of stable epigenetic marks that sit on the nuclear DNA of cancer cells and alter gene expression, defies a prevailing belief that the marks vary so much within each individual's widespread cancers that they have little or no value as targets for therapy or as biomarkers for treatment response and predicting disease severity. 


A new image from the Atacama Pathfinder Experiment (APEX) telescope in Chile shows a beautiful view of clouds of cosmic dust nebula NGC 1999 in the region of Orion. While these dense interstellar clouds seem dark and obscured to visible-light observations, APEX’s LABOCA camera can detect the heat glow of the dust and reveal the hiding places where new stars are being formed. But one of these dark clouds is not what it seems.
