Designing biological movement on the nanometer scale
Synthetic proteins have been created that move in response to their environment in predictable and tunable ways. These motile molecules were designed from scratch on computers, then produced inside living cells.

Galaxy blazes with new stars born from close encounter
The NASA/ESA Hubble Space Telescope has taken a new look at the spectacular irregular galaxy NGC 4485, which has been warped and wound by its larger galactic neighbour. The gravity of the second galaxy has disrupted the ordered collection of stars, gas and dust, giving rise to an erratic region of newborn, hot, blue stars and chaotic clumps and streams of dust and gas.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Pinterest reports smaller 1Q loss but guidance drags stock
Pinterest, fresh off its initial public offering, posted a loss for the first three months of the year that was larger than analysts were expecting, though revenue was slightly stronger. Its revenue outlook, though, was below expectations and its shares slumped in after-hours trading.

Children who use asthma tracking app have better disease control and fewer hospital visits
An app that allows parents and doctors to monitor a child's asthma has a big impact on managing the disease. When families monitored symptoms with eAsthma Tracker and adjusted care accordingly, children had better asthma control and made fewer visits to the emergency department. Using the app also meant that children missed fewer days of school and parents took fewer days off work, improving quality of life. Results of the study were published online in the journal Pediatrics.

Dabigatran doesn't beat aspirin for preventing recurrent stroke
(HealthDay)—Dabigatran is not superior to aspirin for preventing recurrent stroke in patients with recent history of embolic stroke of undetermined source, according to a study published in the May 16 issue of the New England Journal of Medicine.

A new iron-based superconductor stabilized by inter-block charger transfer
Iron-based superconductors (IBSCs) have attracted sustained research attention over the past decade, partly because new IBSCs were discovered one after another in the earlier years. At present, however, exploration of IBSCs becomes more and more challenging. A research team from Zhejiang University developed a structural design strategy for exploration from which they succeeded in finding a series of hole-doped IBSCs with double FeAs layers in recent years. Nevertheless, the electron-doped analogue has not been realized until now.

Researchers shed new light on atomic 'wave function'
Physicists have demonstrated a new way to obtain the essential details that describe an isolated quantum system, such as a gas of atoms, through direct observation. The new method gives information about the likelihood of finding atoms at specific locations in the system with unprecedented spatial resolution. With this technique, scientists can obtain details on a scale of tens of nanometers—smaller than the width of a virus.

Machine learning reduces language barriers in global trade, research shows
Machine learning and artificial intelligence have exploded onto the scene in recent years, offering the hope of greater business efficiency. At the same time, researchers have found virtually no empirical evidence supporting the promised strides in labor productivity and economic activity.

Older and poorer communities are left behind by the decline of cash
A future without cash seems almost inevitable. Recent statistics paint a damning picture: while cash accounted for 62% of all payments by volume in 2006, this dropped to 40% in just a decade and is predicted to fall yet further to 21% by 2026.

Marine organisms hold promise for treating triple negative breast cancer
The oceans cover more than 70 percent of the earth's surface and provide a rich source of unique, bioactive natural products. Their chemical diversity and structural complexity represent an untapped supply of potential new drugs, lead compounds for medicinal chemistry and biological probes to better understand diseases. More than 50 percent of cancer drugs currently used have originated from natural products.

New study shows climate change, maternal care, parasitic infection all connected in South American fur seals
South American fur seal pups with high levels of hookworm infection spend more time in the water, but that's not necessarily a good thing, report Morris Animal Foundation-funded researchers at the University of Georgia.

Cellular rivalry promotes healthy skin development
Not all cells are destined for greatness. Deemed unfit to serve in the body, some are killed off during early development through a process called cell competition. This phenomenon has previously been documented in flies and is now turning out to occur in mammals as well.
