New Research Delivers Hope For More Accurate PTSD Diagnosis And Treatment

Jacob Fadley served four years and 12 tours in Iraq and Afghanistan, repeatedly exposed to heart-thumping blasts. “It’s just like an entire force is being pushed through you, something powerful too,” he described. “Your body just kind of stops and goes, ‘What, what is going on?’ And kind of, for me, it felt like it was rebooting itself.” At the ...

A Majority Of Americans Disagree With Donald Trump’s Hard-Line Stances On Climate Change

Just this month, President Donald Trump issued an order to begin unraveling greenhouse gas regulations, flirted with exiting the Paris Agreement and proposed eliminating funding for climate change research. But the White House’s hard-line stance against taking action to halt global warming appears to be out of step with most of the country, according to a new HuffPost/YouGov poll . More ...

House Science Committee Chair Says Science Magazine Is Not 'Objective'

WASHINGTON — Rep. Lamar Smith  (R-Texas), chairman of the House Committee on Science, Space and Technology, has challenged the credibility of Science magazine — one of the world’s most respected science publications. “That is not known as an objective writer or magazine ,” Smith said during a hearing Wednesday on climate change, which Smith denies. Smith’s comment came after testimony by Michael ...

Top Scientists Defend EPA Air Pollution Studies As Politicians Attack Science

Over a year ago, the Environmental Protection Agency asked the country’s top scientific body to pore over six years of studies into how air pollution affects human health. It was a move meant to quell critics who questioned the safety of conducting such research. The National Academies of Sciences, Engineering, and Medicine finally released its findings on Tuesday, offering a ...

Forensics: Germany considers wider use of DNA evidence in criminal cases

Johannes Simon/Getty Germany plans to hand powerful new DNA tools to investigators. Behind closed doors this week, the German federal justice ministry has been discussing whether to hand police a powerful new tool involving the analysis of DNA samples. The debate is a direct consequence of the rape and murder of a medical student in Freiburg last October. Two months ...

Trump’s pipeline permit is bad for both the US economy and the environment

Brendan Smialowski/AFP/Getty Images An activist outside the Trump International Hotel in Washington DC protests against the controversial Keystone XL pipeline. President Donald Trump last week issued a permit for the Keystone XL pipeline, reversing the decision of his predecessor and fulfilling his own campaign promise. If built, Keystone would enable oil to be shipped from the Canadian tar sands to ...

Cancer: How fat boosts breast cancer

A molecule made by fat cells in human breast tissue increases the growth of certain breast-cancer cells. The finding suggests a potential reason why larger breast size seems to correlate with a higher risk of cancer. Fat cells are thought to interact with cancer cells in the breast. To learn how, Wen-Hwa Lee at China Medical University in Taiwan and ...

Evolution: Diet drives primate brain size

Primates’ large brains may be due to the animals’ diet rather than their social behaviour, challenging a popular theory. Alex DeCasien and her colleagues at New York University compiled existing data on primate brain and body size, and sorted the species into four dietary categories: omnivores, leaf-eaters, fruit-eaters and those that eat both leaves and fruit. The primates that ate ...

Ageing: Senescent cells cleared out

A newly developed molecule causes ageing cells to commit suicide, restoring some signs of health and stamina in old mice. Damaged cells that stop dividing, called senescent cells, accumulate with age, and are thought to contribute to inflammation, tissue damage and age-related diseases. To find ways to clear these cells, Peter de Keizer at the Erasmus University Medical Center in ...

Molecular biology: Drug stalls protein translation

The discovery of a compound that interrupts the production of a specific protein could open up a fresh path to drug discovery. Cells rely on complex molecular machines called ribosomes to translate the genetic code and make proteins. Robert Dullea at Pfizer Worldwide Research and Development in Cambridge, Massachusetts, Jamie Cate at the University of California, Berkeley, and their colleagues ...
