Aboriginal people have been in Australia for at least 65,000 years - much longer than the 47,000 years believed by some archaeologists. The discovery, by a team of archaeologists and dating specialists led by Associate Professor Chris Clarkson from The University of Queensland School of Social Science , has been detailed in the Nature journal this week.

FINDINGS Researchers found in a review of data from three large studies that a minimally invasive treatment to treat peripheral artery disease offers a safe alternative to standard surgery. BACKGROUND Peripheral artery disease is a common circulatory problem in which the arteries become narrow from plaque buildup and blood flow to the limbs is reduced.

A population trend analysis of Bornean orangutans reveals that, despite decades of conservation work, the species is declining rapidly - at a rate of 25 per cent over the past 10 years. University of Queensland School of Biological Sciences researcher Dr Truly Santika , an Indonesian statistician and researcher at the ARC Centre of Centre for Environmental Decisions (CEED), led the study on the critically endangered Bornean orangutans.

Support from Philipp Schwartz Initiative of the Alexander von Humboldt Foundation ' 195/2017 from Jul 12, 2017 Freie Universität was successful in its application for fellowships from the Alexander von Humboldt Foundation for two researchers who are politically at risk in their home countries. As the Humboldt Foundation announced in Bonn, two individuals will be supported through the Philipp Schwartz Initiative to do research at Freie Universität.

A UCL-led study found that homeless people who are terminally ill are falling between cracks in services, and not able to access the same level of support as others. Researchers from the UCL Marie Curie Palliative Care Research Department, Pathway, St Mungo's and Coordinate My Care worked with homeless people and care professionals and found that many homeless people who may be approaching the end of their lives are living in homeless hostels.

As many as one in five older Medicare patients returns to the hospital after an observation stay, or short-term outpatient stay, a Yale-led study found. This high rate of revisit to the hospital points to a hidden vulnerability among these patients, and suggests changes in care might be needed, the researchers said.

A new study sheds light on the depth of health care disparities faced by minority populations in the United States. The findings suggest a possible â?'double jeopardyâ'' for black and Hispanic patients: Not only has it been shown that members of minority groups receive less high-quality, effective care than their peers, they may also be at risk of receiving more low-value, ineffective care.

Professors Jennifer Eberhardt and Dan Jurafsky along with other Stanford researchers detected racial disparities in police officersâ?- speech after analyzing more than 100 hours of body camera footage from Oakland Police. The first systematic analysis of police body camera footage shows that officers consistently use less respectful language with black community members than with white community members, according to new Stanford research.

Teenage pregnancy rates have dropped in areas of the country most affected by government cuts to spending on sex education, according to a new study. In recent years local authorities in England have been forced to make significant cuts to public expenditure, with one particular health target affected: reducing rates of teen pregnancy.

Researchers at the University of Bristol's Centre for Academic Primary Care are looking for men who are concerned that they are, or have been, abusive in their relationships with women to take part in a new study that will help improve how we support men in changing their behaviour. Abusive behaviour can involve a range of actions, including physically hurting someone, pushing or shoving them, frightening them, or controlling or pressuring them into doing what you want or not doing what they want.

Researchers into the common hearing condition 'tinnitus' are calling for help from the public for a new study to try to improve future medical investigations into the problem. The COMIT'ID study is being run by the National Institute for Health Research (NIHR) Nottingham Biomedical Research Centre based at The University of Nottingham.

Research led by University of Birmingham scientists in collaboration with Northwestern University in Chicago, US, has provided fresh insight into the role of male hormone in supporting and disrupting the production of eggs by ovarian follicles. The study, newly published online in the journal Endocrinology, measured for the first time the production of hormones by the isolated ovarian follicle during its development, using highly sensitive and specific mass spectrometry.

Nearly 1 out of every 3 drugs approved by the Food and Drug Administration (FDA) have a new safety issue detected in the years after approval, says a Yale-led study. While most of the safety concerns are not serious enough to require withdrawal of a drug from the market, the finding highlights the need for ongoing surveillance of new drugs in the post-market period, said the researchers.

Under the leadership of the Environmental Sciences Research Network of the University of Vienna, the key national actors in long-term ecological research (LTER) join forces to establish a new infrastructure for the collection of environmental data. Funded by the Austrian Research Promotion Agency (FFG), the project aims to collect data on the effects of extreme climatic events on the carbon, water and nitrogen cycle in ecosystems by establishing six cutting-edge measurement sites.

FINDINGS Forty-four percent of people who held jobs before contracting a condition called acute respiratory distress syndrome were jobless one year after they were discharged from the hospital, costing them an average of about $27,000 in earnings. After one year, fewer of them had private health insurance (30 percent, down from 44 percent) and more of them were enrolled in Medicare and Medicaid (49 percent versus 33 percent).

Illustration shows what each of the TRAPPIST-1 planets may look like, based on available data about their sizes, masses and orbital distances. After NASA announced in February the discovery of a solar system with seven planets'three of which were deemed potentially habitable-UChicago postdoctoral scholar Sebastiaan Krijt began wondering: If a life form existed on one of these planets, could space debris carry it to another?

ANN ARBOR'An examination of millions of scientific papers and patents reveals works that land in the top 5 percent of the most cited research draw upon a mix of old and new knowledge-significant in a day and age when the number of new publications is increasing dramatically, says a researcher at the University of Michigan.

As of October 2017, newly launched car models will have to pass more stringent exhaust gas tests in the EU and in Switzerland. The new test method includes measuring drives in actual traf-fic. Empa already tested currently available cars with the new method - with alarming results. By now, it's no secret: the certification requirements for cars in the EU and in Switzerland have precious little to do with the cars' actual exhaust emissions on the roads.

The ELO system, which most chess federations use today, ranks players by the results of their games. Although simple and efficient, it overlooks relevant criteria such as the quality of the moves players actually make. To overcome these limitations, Jean-Marc Alliot of the Institut de recherche en informatique de Toulouse (IRIT - CNRS/INP Toulouse/Université Toulouse Paul Sabatier/Université Toulouse Jean Jaurès/Université Toulouse Capitole) demonstrates a new system, published on 24 april 2017 in the International Computer Games Association Journal.

Overhunting results in wide-spread declines in tropical mammal & bird populations Tropical mammal and bird populations dramatically decline in overhunted areas - new research reveals. The major study published in the renowned journal Science, reveals hunting accounts for a 83 percent decline in mammal populations and a 58 percent decline in bird populations in the tropical regions of Central and South America, Africa and Asia.
