Spherical silicon nanoparticles about 10 nanometers in diameter that can generate hydrogen...

Researchers at the University of Buffalo have created spherical silicon nanoparticles they claim could lead to hydrogen generation on demand becoming a “just add water” affair. When the particles are combined with water, they rapidly form hydrogen and silicic acid, a nontoxic byproduct, in a reaction that requires no light, heat or electricity. In experiments, the hydrogen produced was shown to be relatively pure by successfully being used to power a small fan via a small fuel cell.  Read More

Gelatins take on a semi-solid state when cool, and become a liquid when heated, right? Well, not always. Chemists from Radboud University Nijmegen, in The Netherlands, have created a “super gel” that behaves in the opposite manner – it’s liquid when cool, and stiffens when heated. What’s more, it reportedly absorbs water 100 times better than other gels. To make it, the researchers copied the protein structure of human cells.  Read More

With Hollywood movie studios increasingly gambling astronomical sums of money on the next big thing, they might want to pay attention to the work being done by Akira Ishii at Tottori University. His research group claims to have developed a mathematical equation that combines advertising, word-of-mouth, and social networks to predict if a movie will be successful.  Read More

Theoretical physicists have worked out how entanglement could be ‘recycled’ to increase th...

An international team of researchers has achieved an important theoretical result by finding that quantum teleportation – the process of transporting quantum information at the speed of light, which could in theory be used to teleport macroscopic objects and, one day, even humans – can be achieved in a much more energy-efficient way than was previously thought.  Read More

The Moon and Jupiter as they might appear in a small telescope (Photo: Gregory H. Revara, ...

Owners of small telescopes, rejoice! For that matter, on the night of January 21 everyone else can also enjoy the sight of Jupiter and the Moon at nearly the same position on the celestial sphere. Here's our advice on how best to observe this – the closest approach of the Moon and Jupiter until 2026.  Read More

For several years now, scientists have been exploring the use of patches of arrayed microneedles as a means of “injecting” medication through the skin. Researchers at North Carolina State University are now working on something similar, but at a much smaller scale – they're developing tiny needle-covered balloons, to deliver medication to individual cells.  Read More

While 3D printing may be touted as bringing manufacturing back to the United States, that doesn't mean the rest of the world hasn't taken notice of the technology. Earlier this week, a 3D Printing Experience Pavilion opened in Beijing's DRC Industrial Design and Cultural Industry Base, where visitors were able to see how 3D printers work firsthand. With a few hours to spare, they could even have their own head scanned and printed as a bust, which follows the 3D printing booth that opened in a Japanese mall last year.  Read More

A UCR researcher is taking inspiration from the teeth of a marine snail to build the techn...

Inspired by the tough teeth of a marine snail and the remarkable process by which they form, assistant professor David Kisailus at the University of California, Riverside is working toward building cheaper, more efficient nanomaterials. By achieving greater control over the low-temperature growth of nanocrystals, his research could improve the performance of solar cells and lithium-ion batteries, lead to higher-performance materials for car and airplane frames, and help develop abrasion-resistant materials that could be used for anything from specialized clothing to dental drills.  Read More

NASA has signed an agreement with the European Space Agency (ESA) for the latter to supply service modules for NASA’s Orion manned spacecraft, due to launch in 2017. The modules will use technology from ESA’s Automated Transfer Vehicle (ATV) currently ferrying supplies to the International Space Station (ISS) and will provide propulsion, power and life support to the Orion module.  Read More

Hubble Ultra Deep Field, showing thousands of galaxies back to a time only a few hundred m...

It is dangerous to bet against Einstein. Cosmological research shows that the rate at which the Universe expands is increasing, rather than decreasing as was previously thought. The concept of "dark energy" with a negative pressure was introduced to describe this acceleration. Now measurements of the proton to electron mass ratio (PEMR) over the past seven billion years strongly suggest that the models of dark energy are far more contrived in explaining accelerating expansion than is Einstein's self-proclaimed "biggest blunder" – the cosmological constant.  Read More
