Published QuanÂtum comÂputer in reverse gear
(via sciencedaily.com) Original source Large numbers can only be factorized with a great deal of computational effort. Physicists are now providing a blueprint for a new type of quantum computer to solve the factorization problem, which is a cornerstone of modern cryptography.
Published 'Gluing' soft materials without glue
(via sciencedaily.com) Original source If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.
Published Engineers tap into good vibrations to power the Internet of Things
(via sciencedaily.com) Original source In a world hungry for clean energy, engineers have created a new material that converts the simple mechanical vibrations all around us into electricity to power sensors in everything from pacemakers to spacecraft.
Published Self-folding origami machines powered by chemical reaction
(via sciencedaily.com) Original source Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Published Quantum entanglement of photons doubles microscope resolution
(via sciencedaily.com) Original source Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Prolonged power outages, often caused by weather events, hit some parts of the U.S. harder than others
(via sciencedaily.com) Original source New research found that Americans already bearing the brunt of climate change and health inequities are most at risk of impact by a lengthy power outage.
Published Researchers develop clever algorithm to improve our understanding of particle beams in accelerators
(via sciencedaily.com) Original source Whenever SLAC National Accelerator Laboratory's linear accelerator is on, packs of around a billion electrons each travel together at nearly the speed of light through metal piping. These electron bunches form the accelerator's particle beam, which is used to study the atomic behavior of molecules, novel materials and many other subjects. But trying to estimate what a particle beam actually looks like as it travels through an accelerator is difficult, leaving scientists often with only a rough approximation of how a beam will behave during an experiment. Now, researchers have developed an algorithm that more precisely predicts a beam's distribution of particle positions and velocities as it zips through an accelerator.
Published Previously unknown intercellular electricity may power biology
(via sciencedaily.com) Original source Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
Published Is the ocean a solution for ushering in the era of environmentally friendly energy?
(via sciencedaily.com) Original source Researchers confirm the superiority of seawater batteries that use chelating agents.
Published Tunneling electrons
(via sciencedaily.com) Original source By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this is the case. The findings could lead to new quantum-mechanical insights and enable electronic circuits that are a million times faster than today.
Published Ingestible 'electroceutical' capsule stimulates hunger-regulating hormone
(via sciencedaily.com) Original source Engineers have shown that by using an ingestible capsule that delivers an electrical current to the cells they can stimulate the release of the hormone ghrelin. This approach could prove useful for treating diseases that involve nausea or loss of appetite, such as anorexia or cachexia.
Published Scientists demonstrate unprecedented sensitivity in measuring time delay between two photons
(via sciencedaily.com) Original source A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range of applications, including more feasible imaging of nanostructures, including biological samples, and nanomaterial surfaces, as well as quantum enhanced estimation based on frequency-resolved boson sampling in optical networks.

(via sciencedaily.com) Original source A team of physicists has illuminated certain properties of quantum systems by observing how their fluctuations spread over time. The research offers an intricate understanding of a complex phenomenon that is foundational to quantum computing.
Published Transforming highways for high-speed travel and energy transport
(via sciencedaily.com) Original source Researchers developed a proof of concept for a superconducting highway that could transport vehicles and electricity, cooling the necessary superconductors with a pipeline of liquid hydrogen. Most magnetic levitation designs feature the superconductor inside the vehicle, which is suspended above a magnetic track. The authors decided to flip that arrangement upside down, putting the superconductor on the ground and giving each vehicle a magnet. The result is a system with multiple uses, placing it within the realm of affordability.
Published Cryo-imaging lifts the lid on fuel cell catalyst layers
(via sciencedaily.com) Original source Thanks to a novel combination of cryogenic transmission electron tomography and deep learning, EPFL researchers have provided a first look at the nanostructure of platinum catalyst layers, revealing how they could be optimized for fuel cell efficiency.
Published Putting hydrogen on solid ground: Simulations with a machine learning model predict a new phase of solid hydrogen
(via sciencedaily.com) Original source Hydrogen, the most abundant element in the universe, is found everywhere from the dust filling most of outer space to the cores of stars to many substances here on Earth. This would be reason enough to study hydrogen, but its individual atoms are also the simplest of any element with just one proton and one electron.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate
(via sciencedaily.com) Original source The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
