Food science and human nutrition researchers are interested in the potential of inflammation-fighting compounds found in the silverskin and husk of coffee beans, not only for their benefits in alleviating chronic disease, but also in adding value to would-be 'waste' products from the coffee processing industry.
The total amount of opioids dispensed per new opioid prescription decreased by 22% in Penn Medicine outpatient practices in New Jersey after the state passed a law limiting prescriptions to a five-day supply for new opioid prescriptions. Penn Medicine implemented an electronic health record (EMR) alert, or 'nudge,' to notify clinicians if that limit had been reached.
The discovery of a fossil of a nearly complete small feathered dinosaur in an Alberta provincial park is providing new information on how "raptor" dinosaurs evolved around the world, new research...
Engineers have developed a way to build soft robots that are compact, portable and multifunctional. The advance was made possible by creating soft, tubular actuators whose movements are electrically controlled, making them easy to integrate with small electronic components. As a proof of concept, engineers used the new actuators to build an untethered, battery-powered, walking soft robot and a...
The planet's warming climate has led to countless changes that are affecting all of us. Droughts, hurricanes, rising sea levels and forest fires—all are now regular events in a world that saw close to 40 billion metric tons of carbon dioxide (CO2) emissions released into our atmosphere last year.
Humankind first started farming in Mesopotamia about 11,500 years ago. Subsequently, the practices of cultivating crops and raising livestock emerged independently at perhaps a dozen other places around the world, in what archaeologists call the Neolithic Agricultural Revolution. It's one of the most thoroughly-studied episodes in prehistory—but a new paper in the Journal of Political Economy...
Fossil fuel companies have worked for decades to shape attitudes and undermine science. The crisis dictates that they must now be confrontedThe huge differences in the voting records of MPs on climate issues, revealed in the Guardian’s rankings today, should immediately disabuse anyone of the notion that Britain’s elected politicians are united – apart from a handful of contrarians – in...
A new study explores the chemistry as well as the complicated and alarming history of DFDT, a fast-acting insecticide.
Anthropogenic noise pollution (ANP) is a globally invasive phenomenon impacting natural systems, but most research has occurred at local scales with few species. Researchers in this study investigated continental-scale breeding season associations with ANP for 322 bird species to test whether local-scale predictions are consistent at broad spatial extents for an extensive group of North American...

For the first time, scientists have printed 3D parts that pave the way to recycling up to 97 percent of the waste produced by nuclear reactors.
The Neolithic Agricultural Revolution is one of the most thoroughly-studied episodes in prehistory. But a new article shows that most explanations for it don't agree with the evidence, and offers a new interpretation.
Extreme high temperatures caused by CO2 emissions could lead to losses in labor productivity. The authors found that every trillion tons of CO2 emitted could cause global GDP losses of about half a percent. They add that we may already be seeing economic losses of as much as 2% of global GDP as a result of what we have already emitted.
Argonne scientists look to 3-D printing to ease separation anxiety, which paves the way to recycle more nuclear material.
