The secret sauce? An improved manufacturing process that eliminates corrosive carbon dioxide gas.

There’s a better way to build solid-state lithium batteries, scientists say. By studying the battery manufacturing process, researchers from the Massachusetts Institute of Technology and Upton, New York-based Brookhaven National Laboratory have eliminated a tiny (but crucial) contamination issue, which could cut down on the complexity in future battery designs.

Solid-state batteries are widely considered to be the next great thing in rechargeable battery design. With an energy capacity at least two times greater than traditional lithium-ion batteries with flammable liquid electrolytes, solid-state batteries are safer, as well as more efficient—a huge pair of selling points for electric consumer vehicles in particular.

The prospects for directly testing a theory of quantum gravity are poor, to put it mildly. To probe the ultra-tiny Planck scale, where quantum gravitational effects appear, you would need a particle accelerator as big as the Milky Way galaxy. Likewise, black holes hold singularities that are governed by quantum gravity, but no black holes are particularly close by — and even if they were, we could never hope to see what’s inside. Quantum gravity was also at work in the first moments of the Big Bang, but direct signals from that era are long gone, leaving us to decipher subtle clues that first appeared hundreds of thousands of years later.

But in a small lab just outside Palo Alto, the Stanford University professor Monika Schleier-Smith and her team are trying a different way to test quantum gravity, without black holes or galaxy-size particle accelerators. Physicists have been suggesting for over a decade that gravity — and even space-time itself — may emerge from a strange quantum connection called entanglement. Schleier-Smith and her collaborators are reverse-engineering the process. By engineering highly entangled quantum systems in a tabletop experiment, Schleier-Smith hopes to produce something that looks and acts like the warped space-time predicted by Albert Einstein’s theory of general relativity.

The Mu2e experiment at Fermilab will look for a never-before-seen subatomic phenomenon that, if observed, would transform our understanding of elementary particles: the direct conversion of a muon into an electron. An international collaboration of over 200 scientists is building the Mu2e precision particle detector that will hunt for new physics beyond the Standard Model.

A gas made of particles of light, or photons, becomes easier to compress the more you squash it. This strange property could prove useful in making highly sensitive sensors.

While gases are normally made from atoms or molecules, it is possible to create a gas of photons by trapping them with lasers. But a gas made this way doesn’t have a uniform density – researchers say it isn’t homogeneous, or pure – making it difficult to study properly.

Now Julian Schmitt at the University of Bonn, Germany, and his colleagues have made a homogeneous photon gas for the first time by trapping photons between two nanoscale mirrors.

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and particle characteristics — known as the particle-wave duality of matter — depending on the scenario, according to the scientific communication site Interesting Engineering.

According to the University of Sussex, American physicist Richard Feynman referred to this paradox as the central mystery of quantum mechanics.

Transmutex is reinventing nuclear energy from first principles using a process that uses radioactive waste as a fuel source.

Transmutex, a Swiss company, states on its website that it is “reinventing nuclear energy from first principles” by using a process that uses radioactive waste as a fuel source.

Its transmitter is a particle accelerator that produces nuclear energy with fewer contaminants than any reactor on the market today. The technology represents a valuable tool in the transition to intermittent renewables by providing baseload energy-producing alternatives to fossil-fuel thermal power stations.

Space weather experts have spotted the sun ejecting a large mass of particles and think this could hit Earth in the next few days.

When ejections like this hit Earth’s magnetic field, they can cause solar storms.

An ejection like this is known as a solar flare called a coronal mass ejection (CME).

A team of researchers affiliated with multiple institutions in China and the U.S. has found that it is possible to track the sliding of grain boundaries in some metals at the atomic scale using an electron microscope and an automatic atom tracker. In their paper published in the journal Science, the group describes their study of platinum using their new technique and the discovery they made in doing so.

Scientists have been studying the properties of metals for many years. Learning more about how crystal grains in certain metals interact with one another has led to the development of new kinds of metals and applications for their use. In their recent effort, the researchers took a novel approach to studying the sliding that occurs between grains and in so doing have learned something new.

When crystalline metals are deformed, the grains that they are made of move against one another, and the way they move determines many of their properties, such as malleability. To learn more about what happens between grains in such metals during deformity, the researchers used two types of technologies: transmission electron microscopy and automated atom-tracking.

As scientists prepared in 2010 to collapse the first particles in the Large Hadron Collider (LHC), media representatives imagined that the EU-wide experiment could create a black hole that could swallow and destroy our planet. How on earth, columnists rage, could scientists justify such a dangerous indulgence for the pursuit of abstract, theoretical knowledge?
