Researchers report a new quantum sensing technique that allows high-resolution nuclear magnetic resonance spectroscopy on small molecules in dilute solution in a 10 picoliter sample volume -- roughly equivalent to a single cell.
NASA's IBEX charts 11 years of change at boundary to interstellar space
- ScienceDaily
- 20/6/17 23:48
Now, for the first time, scientists have used an entire solar cycle of data from NASA's IBEX spacecraft to study how the heliosphere changes over time. Solar cycles last roughly 11 years, as the Sun swings from seasons of high to low activity, and back to high again. The results show the shifting outer heliosphere in great detail and hint at processes behind one of its most puzzling features.

Researchers looking at mouse models found impaired functional interactions between the hippocampus and the parietal cortex during the memory replay period, which may yield new insights into Alzheimer's Disease.
Adhesive film turns smartwatch into biochemical health monitoring system
- ScienceDaily
- 20/6/17 23:48
Engineers have designed a thin adhesive film that could upgrade a consumer smartwatch into a powerful health-monitoring system. The system looks for chemical indicators found in sweat to give a real-time snapshot of what's happening inside the body.
Seeing corneal degeneration in a new light
- ScienceDaily
- 20/6/17 23:48
The molecular changes that lead to Fuchs' endothelial corneal dystrophy (FECD) occur decades before the disease causes blurry vision and other noticeable symptoms in patients, new research shows. This insight into this earliest stage of FECD may eventually lead to new ways of screening for and treating the common condition, which affects an estimated 4 percent of U.S. adults over the age of 40.

Mechanical engineers and computer scientists have developed a 3D printing technique that uses motion capture technology, similar to that used in Hollywood movies, to print electronic sensors directly on organs that are expanding and contracting.
A step forward in solving the reactor-neutrino flux problem
- ScienceDaily
- 20/6/17 21:00
A nuclear theory group experiment paves the way for solving the reactor antineutrino flux problems. The experiment is designed to measure the mass of the neutrino. As a by product of the calibration efforts of the experiment the electron spectral shape of the beta decay of Xe-137 could be measured.
'Cooperative' and 'independent' dog breeds may not react differently to unfair outcomes
- ScienceDaily
- 20/6/17 21:00
Cooperative-worker dog breeds do not appear to respond more negatively to unfair outcomes than do independent-worker breeds, according to a new study. Although the sample size was small, the results do not support the hypothesis that inequity aversion and cooperation co-evolved.
Is Santa real? Examining children's beliefs in cultural figures and 'non-real' people
- ScienceDaily
- 20/6/17 21:00
Young children understand dinosaurs and The Wiggles are (or were!) real, and that fictional characters like Peter Pan and Spongebob are not real -- but cultural figures like Santa or the Tooth Fairy occupy an ambiguous place in a child's pantheon, a new study suggests.
Manipulating tiny skyrmions with small electric currents
- ScienceDaily
- 20/6/17 21:00
A research group has managed to manipulate and track the movement of individual magnetic vortices called skyrmions, which have been touted as strong candidates to act as information carriers in next-generation storage devices and as synapses for neuromorphic computing.
Soap bubbles pollinated a pear orchard without damaging delicate flowers
- ScienceDaily
- 20/6/17 21:00
Soap bubbles facilitated the pollination of a pear orchard by delivering pollen grains to targeted flowers, demonstrating that this whimsical technique can successfully pollinate fruit-bearing plants. The study suggests that soap bubbles may present a low-tech complement to robotic pollination technology designed to supplement the work of vanishing bees.
Shift in how we build computers: Photonics
- ScienceDaily
- 20/6/17 21:00
Information technology continues to progress at a rapid pace. However, the growing demands of data centers have pushed electrical input-output systems to their physical limit, which has created a bottleneck. Maintaining this growth will require a shift in how we built computers. The future is optical.
A changing mating signal may initiate speciation in populations of Drosophila mojavensis
- ScienceDaily
- 20/6/17 21:00
When choosing a mate, females of different subspecies of Drosophila mojavensis recognize the right mating partners either mainly by their song or by their smell. New species apparently evolve when the chemical mating signal is altered and when, in turn, the signal is reinterpreted by the opposite sex in the context of other signals, such as the courtship song.
Quasar jets are particle accelerators thousands of light-years long
- ScienceDaily
- 20/6/17 21:00
An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars is not concentrated in the region close to their central black hole but in fact extends over several thousand light-years along jets of plasma. This discovery shakes up current scenarios for the behaviour of such plasma jets.
Fighting fish synchronize their combat moves and their gene expression
- ScienceDaily
- 20/6/17 21:00
When two betta fish are fighting for dominance, not only do their attacks mirror each other, but the gene expression in their brain cells also starts to align. The new findings may explain how the fish synchronize their fighting behavior.
First dinosaur eggs were soft like a turtle's
- ScienceDaily
- 20/6/17 21:00
New research suggests that the first dinosaurs laid soft-shelled eggs -- a finding that contradicts established thought. The study analyzed the eggs of two vastly different non-avian dinosaurs and found that they resembled those of turtles in their microstructure, composition, and mechanical properties. The research also suggests that hard-shelled eggs evolved at least three times independently in...
Knock-knock? Who's there? How coral let symbiotic algae in
- ScienceDaily
- 20/6/17 21:00
Biologists have solved a longstanding marine science mystery that could aid coral conservation. The researchers identified the type of cell that enables a soft coral to recognize and take up the photosynthetic algae with which it maintains a symbiotic relationship, as well as the genes responsible for this transaction.

Wind farms on the Black Sea coast could endanger bat populations in Eastern Europe
- ScienceDaily
- 20/6/17 21:00
The Via Pontica, an important migration route for birds in Eastern Europe, runs along the Black Sea coast of Romania and Bulgaria. Bats also use this route. In this region, numerous wind farms have been installed in recent years because of good wind conditions. A research team has now demonstrated that this leads to high death rates of migrating bats and potentially large declines even in...
RNA structures by the thousands
- ScienceDaily
- 20/6/17 20:59
Researchers have developed a new method to determine the structures of all RNA molecules in a bacterial cell at once. In the past, this had to be done individually for each molecule. Besides their exact composition, their structure is crucial for the function of the RNAs. The team has now described the new high-throughput structure mapping method.
