Density functional theory took a wrong turn recently
A new study by scientists from A.N. Nesmeyanov Institute of Organoelement Compounds, Moscow, Russia, and Temple University, Philadelphia, Pa., USA shows that the density functional theory, the bread and butter of modern computational chemistry, has significantly deviated in the recent years from the theoretical foundations it was built upon. The results were published in Science.

South American fossil tomatillos show nightshades evolved earlier than thought
Delicate fossil remains of tomatillos found in Patagonia, Argentina, show that this branch of the economically important family that also includes potatoes, peppers, tobacco, petunias and tomatoes existed 52 million years ago, long before the dates previously ascribed to these species, according to an international team of scientists.

Study finds potential instability in Atlantic Ocean water circulation system
One of the world's largest ocean circulation systems may not be as stable as today's weather models predict, according to a new study. In fact, changes in the Atlantic Meridional Overturning Circulation -- the same deep-water ocean current featured in the movie 'The Day After Tomorrow' -- could occur quite abruptly, in geologic terms, the study says.

New technique uses immune cells to deliver anti-cancer drugs
Some researchers are working to discover new, safer ways to deliver cancer-fighting drugs to tumors without damaging healthy cells. Others are finding ways to boost the body's own immune system to attack cancer cells. Researchers at Penn State have combined the two approaches by taking biodegradable polymer nanoparticles encapsulated with cancer-fighting drugs and incorporating them into immune cells to create a smart, targeted system to attack cancers of specific types.

Fast radio burst tied to distant dwarf galaxy, and perhaps magnetar
Since first detected 10 years ago, fast radio bursts have puzzled astronomers. Unlike pulsars, they flash irregularly, most only once, and only for milliseconds. And they seem to come from outside the galaxy, meaning they are very energetic. A team of astronomers has now localized the only repeating burst, to a distant dwarf galaxy. UC Berkeley's Casey Law, who created the rapid data collection and analysis software on the VLA, sees a connection to magnetars.

280 million-year-old fossil reveals origins of chimaeroid fishes
High-definition CT scans of the fossilized skull of a 280 million-year-old fish reveal the origin of chimaeras, a group of cartilaginous fish related to sharks. Analysis of the brain case of Dwykaselachus oosthuizeni, a shark-like fossil from South Africa, shows telltale structures of the brain, major cranial nerves, nostrils and inner ear belonging to modern-day chimaeras.

Manufacturing platform makes intricate biocompatible micromachines
Columbia Engineering researchers have developed a way to manufacture microscale-sized machines from biomaterials that can safely be implanted in the body. Working with hydrogels, they have invented a new technique that stacks the soft material in layers to make devices that have three-dimensional, freely moving parts. The study demonstrates a fast manufacturing method they call 'implantable microelectromechanical systems.'

Nanowire 'inks' enable paper-based printable electronics
Thin films made from silver nanowires are 4,000 times more conductive than films made from other nanoparticle shapes, like spheres or microflakes, says a new study by Duke University researchers. The results indicate that conductive 'inks' made from silver nanowires may create functioning electronic circuits without applying high temperatures, enabling printable electronics on heat-sensitive materials like paper or plastic.

Tenfold jump in green tech needed to meet global emissions targets
The global spread of green technologies must quicken significantly to avoid future rebounds in climate-warming emissions, a Duke study shows. Based on the new calculations, the Paris Agreement's warming target of 2 degrees C won't be met unless clean technologies are developed and implemented at rates 10 times faster than in the past. Radically new strategies to implement technological advances are needed.

Will climate change leave tropical birds hung out to dry?
The future of the red-capped manakin and other tropical birds in Panama looks bleak. A University of Illinois research project spanning more than three decades and simulating another five decades analyzes how changes in rainfall will affect bird populations. The results show that for 19 of the 20 species included in the study, there may be significantly fewer birds if conditions become dryer.

Detecting misinformation can improve memory later on
Exposure to false information about an event usually makes it more difficult for people to recall the original details, but new research suggests that there may be times when misinformation actually boosts memory. Research published in Psychological Science, a journal of the Association for Psychological Science, shows that people who actually notice that the misinformation is inconsistent with the original event have better memory for the event compared with people who never saw the misinformation in the first place.
