Theorists publish highest-precision prediction of muon magnetic anomaly
Posted on Friday July 13, 2018

Latest calculation based on how subatomic muons interact with all known particles comes out just in time for comparison with precision measurements at new 'Muon g-2' experiment.

Barium ruthenate: A high-yield, easy-to-handle perovskite catalyst for the oxidation of sulfides
Posted on Friday July 13, 2018

Researchers have developed a ruthenium-based perovskite catalyst that shows strong activity even at low temperatures (down to 313 K). The reusable catalyst does not require additives, meaning that it can prevent the formation of toxic by-products. The oxidation of sulfides is a commercially important process with broad applications ranging from chemicals production to environmental management.

New study reveals Ulsan, South Korea, is exposed to yearlong toxic fine dust
Posted on Friday July 13, 2018

A new study offers decisive proof that South Korea's Ulsan city is affected by toxic substances contained in fine dust particles, regardless of the season.

Teaching robots to be more reliable teammates for soldiers
Posted on Friday July 13, 2018

Researchers have developed a new technique to quickly teach robots novel traversal behaviors with minimal human oversight.

How might dark matter interact with ordinary matter?
Posted on Friday July 13, 2018

Scientists have imposed conditions on how dark matter may interact with ordinary matter. In the search for direct detection of dark matter, the experimental focus has been on WIMPs, or weakly interacting massive particles, the hypothetical particles thought to make up dark matter. But the research team invokes a different theory to challenge the WIMP paradigm: the self-interacting dark matter model, or SIDM.

Scientists on Twitter: Preaching to the choir or singing from the rooftops?
Posted on Friday July 13, 2018

Who follows scientists on Twitter? Researchers found that scientists with fewer than 1,000 followers primarily reach other scientists. However, scientists with more than 1,000 followers have more types of followers, including those in the "outreach" category.

Graphene could be key to controlling water evaporation
Posted on Friday July 13, 2018

Graphene coatings may offer the ability to control the water evaporation process from various surfaces, according to new research. The study looked at the interactions of water molecules with various graphene-covered surfaces.

Bioengineers create pathway to personalized medicine
Posted on Thursday July 12, 2018

New work could provide sustainable ways to make chemicals, medicines and biomaterials.

New molecular structures in boron-based nanoclusters
Posted on Thursday July 12, 2018

Researchers have shown that clusters of boron and lanthanide atoms form interesting 'inverse sandwich' structures that could be useful as molecular magnets.

Turn exercise into a game and see encouraging results
Posted on Thursday July 12, 2018

A team of researchers built a web-based app called MapTrek. When synced with a Fitbit, MapTrek allows users to go on virtual walking tours of locations such as the Grand Canyon or Appalachian trail while competing against other users. A study showed MapTrek and Fitbit users averaged 2,200 more steps per day than a control group that used only Fitbits.

First machine learning method capable of accurate extrapolation
Posted on Thursday July 12, 2018

Understanding how a robot will react under different conditions is essential to guaranteeing its safe operation. But how do you know what will break a robot without actually damaging it? A new machine learning method can use observations made under safe conditions to make accurate predictions for all possible conditions governed by the same physical dynamics.

Wearable device can predict older adults' risk of falling
Posted on Thursday July 12, 2018

Every year, more than one in three individuals aged 65 and older will experience a fall. Treatment and awareness of falling usually happens after a fall has already occurred. Researchers wanted to see if they could predict an individual's risk of falling so that preventative measures could be taken to reduce this risk.

Solved protein puzzle opens door to new design for cancer drugs
Posted on Thursday July 12, 2018

Researchers at have solved a longstanding puzzle concerning the design of molecular motors, paving the way toward new cancer therapies.

VERITAS supplies critical piece to neutrino discovery puzzle
Posted on Thursday July 12, 2018

The VERITAS array has confirmed the detection of gamma rays from the vicinity of a supermassive black hole. While these detections are relatively common for VERITAS, this black hole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle.

Breakthrough in the search for cosmic particle accelerators
Posted on Thursday July 12, 2018

In a global observation campaign, scientist have for the first time located a source of high-energy cosmic neutrinos, ghostly elementary particles that travel billions of light years through the universe, flying unaffected through stars, planets and entire galaxies.

Quantum dot white LEDs achieve record efficiency
Posted on Thursday July 12, 2018

Researchers have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt.

How gold nanoparticles could improve solar energy storage
Posted on Thursday July 12, 2018

Star-shaped gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods - opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to researchers.

Hubble and Gaia team up to fuel cosmic conundrum
Posted on Thursday July 12, 2018

Using the power and synergy of two space telescopes, astronomers have made the most precise measurement to date of the universe's expansion rate.

Chemists achieve unprecedented molecular triple jump with multi-ringed metal complexes
Posted on Thursday July 12, 2018

For decades, chemists have been mixing metals and carbon to create novel molecules, from the world's longest molecular wires to microscopic gyroscopes controllable by cage size, molecular access and even progress toward unidirectional rotation via external electrical field manipulation.

Could gravitational waves reveal how fast our universe is expanding?
Posted on Thursday July 12, 2018

An new study finds black holes and neutron stars are key to measuring our expanding universe.
