Liquid metal discovery to make toxic water safe and drinkable
Posted on Tuesday September 25, 2018

Researchers have discovered a revolutionary and cheap way to make filters that can turn water contaminated with heavy metals into safe drinking water in a matter of minutes.

Transforming carbon dioxide
Posted on Tuesday September 25, 2018

A new technique to increase the efficiency of carbon dioxide (CO2) electrolysis that may lead to the production of new chemicals and fuels.

Multimodal imaging shows strain can drive chemistry in a photovoltaic material
Posted on Tuesday September 25, 2018

A unique combination of imaging tools and atomic-level simulations has allowed a team to solve a longstanding debate about the properties of a promising material that can harvest energy from light.

Patterns in STEM grades of girls versus boys
Posted on Tuesday September 25, 2018

A new study has explored patterns in academic grades of 1.6 million students, showing that girls and boys perform very similarly in STEM - including at the top of the class.

Heterometallic copper-aluminum superatom discovered
Posted on Tuesday September 25, 2018

On the outside, the cluster made of 55 copper and aluminum atoms looks like a crystal, but chemically it has the properties of an atom. The heterometallic superatom which chemists have created provides the prerequisites for developing new, more cost-effective catalysts.

Tumor cell expansion challenges current physics
Posted on Tuesday September 25, 2018

A malignant tumor is characterized by its ability to spread around its surroundings. To do so, tumor cells stick to the surrounding tissue (mainly collagen) and use forces to propel. New research reveals the forces these tumor cells use to spread. The relation between these forces and the cell movement goes beyond current physical laws, according to researchers.

Funded by new tax credits, US carbon-capture network could double global CO2 headed underground
Posted on Tuesday September 25, 2018

Researchers have proposed a US pipeline network that would capture, transport and store underground up to 30 million metric tons of carbon dioxide emissions each year -- an amount equal to removing 6.5 million cars from the road. The authors found that the network infrastructure would only be possible if tax credits passed by Congress in 2018 to encourage investment in carbon capture-and-storage technology are coupled with low-interest government financing.

Chemical engineers functionalize boron nitride with other nanosystems
Posted on Tuesday September 25, 2018

Scientists report that treatment with a superacid causes boron nitride layers to separate into atomically thick sheets, while creating binding sites on the surface of these sheets that provide opportunities to interface with nanoparticles, molecules and other 2D nanomaterials, like graphene.

Illegal ivory dealers starting to use similar code words to hide online sales
Posted on Tuesday September 25, 2018

Ivory sellers in Europe using eBay are using the same code words across different languages to covertly advertise items for sale, potentially making it easier for law enforcement agencies to uncover such activities by reducing the number of phrases they have to track.

Artificial intelligence to improve drug combination design and personalized medicine
Posted on Tuesday September 25, 2018

A new auto-commentary looks at how an emerging area of artificial intelligence, specifically the analysis of small systems-of-interest specific datasets, can be used to improve drug development and personalized medicine.

New earthquake risk model could better inform disaster planning
Posted on Monday September 24, 2018

Researchers have developed a new way to model seismic risk, which they hope will better inform disaster risk reduction planning in earthquake-prone areas.

Wigner crystal -- not Mott insulator -- in 'magic-angle' graphene
Posted on Monday September 24, 2018

Recently, scientists created a stir in the field of condensed matter physics when they showed that two sheets of graphene twisted at specific angles display two emergent phases of matter. After a careful review of the experimental data researchers say that the insulating behavior of the ''magic-angle'' graphene is not Mott insulation, but something even more profound -- a Wigner crystal.

Astronomers use Earth's natural history as guide to spot vegetation on new worlds
Posted on Monday September 24, 2018

By looking at Earth's full natural history and evolution, astronomers may have found a template for vegetation fingerprints -- borrowing from epochs of changing flora -- to determine the age of habitable exoplanets.

Crowd counting through walls with WiFi
Posted on Monday September 24, 2018

Researchers have given the first demonstration of crowd counting through walls using only everyday communication signals such as WiFi. The technique, which requires only a wireless transmitter and receiver outside the area of interest, could have a variety of applications, including smart energy management, retail business planning and security.

Martian moon may have come from impact on home planet
Posted on Monday September 24, 2018

Phobos, the larger of Mars' two tiny satellites, is the darkest moon in the solar system. This dark aspect inspired the hypothesis that the close-orbiting moon may be a captured asteroid, but its orbital dynamics seemed to disagree. A new study suggests Phobos' composition may be more like the volcanic crust of the Red Planet than it appears, consistent with an origin for the moon in an ancient, violent impact on Mars.

How will climate change stress the power grid? Hint: Look at dew point temperatures
Posted on Monday September 24, 2018

A new study suggests the power industry is underestimating how climate change could affect the long-term demand for electricity in the United States. The research describes the limitations of prediction models used by electricity providers and regulators for medium- and long-term energy forecasting. It outlines a new model that includes key climate predictors that researchers say present a more accurate view of how climate change will alter future electricity demands.

Four extremely young asteroid families identified
Posted on Monday September 24, 2018

Researchers dated the families using a numerical simulation method to process current data to go back in time to the asteroid formation era.

Shedding light on -- and through -- 2D materials
Posted on Monday September 24, 2018

Scientists use a computational method to calculate the optical properties of two-dimensional materials. Their work promises to simplify the process of identifying the right materials for next-generation optoelectronic devices.

Quantum computing: A new way to count qubits
Posted on Monday September 24, 2018

Researchers have developed a new technique for measuring the state of quantum bits, or qubits, in a quantum computer.

Smaller, faster and more efficient modulator sets to revolutionize optoelectronic industry
Posted on Monday September 24, 2018

A research team has successfully fabricated a tiny on-chip lithium niobate modulator, an essential component for the optoelectronic industry. The modulator is smaller, more efficient with faster data transmission and costs less than traditional ones.
