Wed, 07 Dec 2016 15:54:13 ESTNeonicotinoids—the most widely used class of insecticides—significantly reduce populations of predatory insects when used as seed coatings, according to researchers at Penn State. The team's research challenges the previously held belief that neonicotinoid seed coatings have little to no effect on predatory insect populations. In fact, the work suggests that neonicotinoids reduce populations of insect predators as much as broadcast applications of commonly used pyrethroid insecticides.
Wed, 07 Dec 2016 15:51:54 ESTSockeye salmon that evolved in the generally colder waters of the far north still know how to cool off if necessary, an important factor in the species' potential for dealing with global climate change.
Wed, 07 Dec 2016 15:47:15 ESTUsing marine sediment cores containing isotopes of aluminum and beryllium, a group of international researchers has discovered that East Greenland experienced deep, ongoing glacial erosion over the past 7.5 million years.
Wed, 07 Dec 2016 15:42:55 ESTInflammation is a good thing when it's fighting off infection, but too much can lead to autoimmune diseases or cancer. In efforts to dampen inflammation, scientists have long been interested in CC chemokine receptor 2 (CCR2)—a protein that sits on the surface of immune cells like an antenna, sensing and transmitting inflammatory signals that spur cell movement toward sites of inflammation. Researchers at the Skaggs School of Pharmacy and Pharmaceutical Sciences at University of California San Diego have now determined the 3D structure of CCR2 simultaneously bound to two inhibitors. Understanding how these molecules fit together may better enable pharmaceutical companies to develop anti-inflammatory drugs that bind and inhibit CCR2 in a similar manner.

Wed, 07 Dec 2016 14:00:07 ESTThe next time you place your coffee order, imagine slapping onto your to-go cup a sticker that acts as an electronic decal, letting you know the precise temperature of your triple-venti no-foam latte. Someday, the high-tech stamping that produces such a sticker might also bring us food packaging that displays a digital countdown to warn of spoiling produce, or even a window pane that shows the day's forecast, based on measurements of the weather conditions outside.
Wed, 07 Dec 2016 14:00:07 ESTAs the floor plan of the living world, DNA guides the composition of animals ranging from unicellular organisms to humans. DNA not only helps shepherd every organism from birth through death, it also plays an essential role in the development of many human diseases.
Wed, 07 Dec 2016 13:18:25 ESTWeed scientists in at least two Midwestern states have been reporting for years that a conservation program meant to provide habitat for pollinating insects is sowing bad seeds - including seeds of the potentially devastating agricultural weed Palmer amaranth - along with the good. Now, researchers at the University of Illinois have traced the weed seeds to at least one source: pollinator habitat seed sold by a company in the Midwest.
Wed, 07 Dec 2016 13:17:39 ESTThe Earth's critical zone isn't called critical for nothing. Known as our planet's outer skin, it is essential for human survival.
Wed, 07 Dec 2016 13:17:09 ESTUniversity of Illinois Electrical & Computer Engineering and Bioengineering Professor Brian Cunningham's Nano Sensors group has invented a novel live-cell imaging method that could someday help biologists better understand how stem cells transform into specialized cells and how diseases like cancer spread. Their Photonic Crystal Enhanced Microscope (PCEM) is capable of monitoring and quantitatively measuring cell adhesion, a critical process involved cell migration, cell differentiation, cell division, and cell death.
Wed, 07 Dec 2016 13:00:06 ESTThe ice sheet covering Greenland is four times bigger than California—and holds enough water to raise global sea-level more than twenty feet if most of it were to melt. Today, sea levels are rising and the melting of Greenland is a major contributor. Understanding how fast this melting might proceed is a pressing question for policymakers and coastal communities.
Wed, 07 Dec 2016 12:55:16 ESTLiving in deep reefs in the Atlantic Ocean, the banded basslet, a small and colorful species with a wide range of distribution, has long been thought to undergo significant changes during its growth into an adult. Suspiciously, the juveniles appeared much more heavily banded. Recently, however, American scientists figured out that the 'juveniles' were in fact a new species.

Wed, 07 Dec 2016 12:17:32 ESTThe increasingly popular subject of raw diffraction data deposition is examined in a Topical Review in IUCrJ. Building on the 2015 workshop organised by the IUCr Diffraction Data Deposition Working Group (DDDWG), the authors bring the story up to date with accounts of new subject-specific and institutional data repositories, and of growing policy pressures on research data management such as the European Open Science initiative.
Wed, 07 Dec 2016 12:14:45 ESTScientists have called superoxide out as the main culprit behind coral bleaching: The idea is that as this toxin build up inside coral cells, the corals fight back by ejecting the tiny energy- and color-producing algae living inside them. In doing so, they lose their vibrancy, turn a sickly white, and are left weak, damaged, and vulnerable to disease.
Wed, 07 Dec 2016 11:40:01 ESTIt's a sure-fire way to dampen the holiday cheers: Spend a week on a dream vacation abroad, then come back to find an additional several hundred dollars on your cellphone bill.
Wed, 07 Dec 2016 11:27:07 ESTIt's that time of year again: when festive ads command consumers to BUY! BUY! BUY! for their friends and family. But despite this holiday cheer, negative news marches on.
Wed, 07 Dec 2016 11:26:20 ESTIn 2014, the number of deaths from opioid overdoses in the U.S. jumped to its highest level on record. The spike brought national attention to the epidemic and the awareness that new interventions are needed. Now researchers are developing opioid vaccines that could one day help protect people from dying of overdoses. Their study, which tested the vaccines on mice, appears in the journal ACS Chemical Biology.
Wed, 07 Dec 2016 11:04:36 ESTHelium atoms are loners. Only if they are cooled down to an extremely low temperature do they form a very weakly bound molecule. In so doing, they can keep a tremendous distance from each other thanks to the quantum-mechanical tunnel effect. As atomic physicists in Frankfurt have now been able to confirm, over 75 percent of the time they are so far apart that their bond can be explained only by the quantum-mechanical tunnel effect.
Wed, 07 Dec 2016 11:03:48 ESTWater is vital to life on Earth and its importance simply can't be overstated—it's also deeply rooted within our conscience that there's something extremely special about it. Yet, from a scientific point of view, much remains unknown about water and its many solid phases, which display a plethora of unusual properties and so-called anomalies that, while central to water's chemical and biological importance, are often viewed as controversial.
