Most batteries are composed of two solid, electrochemically active layers called electrodes, separated by a polymer membrane infused with a liquid or gel electrolyte. But recent research has explored the possibility of all-solid-state batteries, in which the liquid (and potentially flammable) electrolyte would be replaced by a solid electrolyte, which could enhance the batteries’ energy density and safety.

There is an improved build strategy for the second Gerald R. Ford aircraft carrier. The Kennedy carrier (CVN-79)is being built using more modular construction, a process where smaller sections of the ship are welded together to form large structural units, equipment is installed, and the large units are lifted into the dry dock using the shipyard’s 1,050-metric ton gantry crane. The modules can weigh over 1000 tons.

Developing efficient photoreversible color switching systems for constructing rewritable paper is of significant practical interest owing to the potential environmental benefits including forest conservation, pollution reduction, and resource sustainability. Here we report that the color change associated with the redox chemistry of nanoparticles of Prussian blue and its analogues could be integrated with the photocatalytic activity of TiO2 nanoparticles to construct a class of new photoreversible color switching systems, which can be conveniently utilized for fabricating ink-free, light printable rewritable paper with various working colors. The current system also addresses the phase separation issue of the previous organic dye-based color switching system so that it can be conveniently applied to the surface of conventional paper to produce an ink-free light printable rewritable paper that has the same feel and appearance as the conventional paper. With its additional advantages such as excellent scalability and outstanding rewriting performance (reversibility over 80 times, legible time over 5 days, and resolution over 5 μm), this novel system can serve as an eco-friendly alternative to regular paper in meeting the increasing global needs for environment protection and resource sustainability.

The quantity and quality of satellite-geodetic measurements of tectonic deformation have increased dramatically over the past two decades improving our ability to observe active tectonic processes. We now routinely respond to earthquakes using satellites, mapping surface ruptures and estimating the distribution of slip on faults at depth for most continental earthquakes. Studies directly link earthquakes to their causative faults allowing us to calculate how resulting changes in crustal stress can influence future seismic hazard. This revolution in space-based observation is driving advances in models that can explain the time-dependent surface deformation and the long-term evolution of fault zones and tectonic landscapes.

Until now, the high cost of graphene production has been the major roadblock in its commercialiZation. Previously, graphene was grown in a highly-controlled environment with explosive compressed gases, requiring long hours of operation at high temperatures and extensive vacuum processing. Australian CSIRO scientists have developed a novel “GraphAir” technology which eliminates the need for such a highly-controlled environment. The technology grows graphene film in ambient air with a natural precursor, making its production faster and simpler.

Of the three types of Lockheed Martin’s F-35 Joint Strike Fighter, only the US Navy's carrier-launched F-35C is at risk of being replaced by Boeing’s F-18 Super Hornet, the Marine Corps’s top pilot said today. It’s not on the table to substitute Hornets for either the land-based F-35A variant or the vertical-takeoff-and-landing F-35B, Lt. Gen. Jon Davis, deputy Commandant for aviation said today.

Researchers doubt the Harvard claim that solid metallic hydrogen has been created Ranga Dias and Isaac Silvera, both physicists at Harvard University in Cambridge, Massachusetts, first posted a report of their results on the arXiv preprint server last October, which attracted immediate criticism. A peer-reviewed version of the report was published on 26 January in Science2, but sceptics say that it includes little new information. Silvera and Dias say that they wanted to publish their first observation before making further tests on their fragile material.

Beijing's second aircraft carrier was "taking shape" after two years and nine months of construction, mainland Chinese media reported - a move likely to further unnerve Taiwan and other neighbors about their growing military assertiveness. Construction of the Shandong, named after province in China's east coast, began in 2014, the mobile app of Shandong television and radio said in a report seen on Tuesday.

Three massive battery storage plants—built by Tesla, AES Corp., and Altagas Ltd.—are all officially going live in southern California at about the same time. Any one of these projects would have been the largest battery storage facility ever built. Combined, they amount to 15 percent of the battery storage installed planet-wide last year.

China's One Belt One Road has proved to be a boon for trans-Eurasian rail transport, as these new rail lines would become its vanguard, establishing physical links between many of the key countries and a platform of cooperation from which to drive closer diplomatic and economic ties. What started out as two regular routes emerging from booming high-tech zones in Chongqing and Chengdu rapidly grew into a 39 route network linking together dozens of cities in China and Europe.

This study is expected to improve the limited size and viewing angle of 3D images, which were a major problem of the current holographic displays

Homes with solar panels do not require on-site storage to reap the biggest economic and environmental benefits of solar energy, according to research from the Cockrell School of Engineering at The University of Texas at Austin. In fact, storing solar energy for nighttime use actually increases both energy consumption and emissions compared with sending excess solar energy directly to the utility grid.

Organovo designs and create functional human tissues using our proprietary three-dimensional bioprinting technology. Their goal is to build living human tissues that are proven to function like native tissues. With reproducible 3D tissues that accurately represent human biology, they are enabling ground-breaking therapies by:

Every year about 120,000 organs, mostly kidneys, are transplanted from one human being to another. Sometimes the donor is a living volunteer. Usually, though, he or she is the victim of an accident, stroke, heart attack or similar sudden event that has terminated the life of an otherwise healthy individual. But a lack of suitable donors, particularly as cars get safer and first-aid becomes more effective, means the supply of such organs is limited. Many people therefore die waiting for a transplant. That has led researchers to study the question of how to build organs from scratch.

Devastating tsunamis could be halted before hitting the Earth’s shoreline by firing deep-ocean sound waves at the oncoming mass of water, new research has proposed.

Doctors in London say they have cured two babies of leukemia in the world’s first attempt to treat cancer with genetically engineered immune cells from a donor.

It will likely to launch within two years, the machine will again double the number of qubits, to around 4,000. Crucially, it will also provide more-complex connections between qubits, allowing it to tackle more-complicated problems.

Ukraine has test fired for the first time newly designed engine AI-136T. It is intended for China's super heavy helicopter program. The helicopter itself is planned to be based on Soviet MI-26 airframe design, although scaled down somewhat to a smaller size. In combination with more powerful engine than previously used, new helicopter is expected to be a much more energetic machine, with higher combat ceiling, higher speed and better maneuverability. Expected payload capacity is 30 tons.

A construction robot has to be powerful enough to handle heavy material, small enough to enter standard buildings, and flexible enough to navigate the terrain.

Computer scientists at Stanford set out to create an artificially intelligent diagnosis algorithm for skin cancer. They made a database of nearly 130,000 skin disease images and trained their algorithm to visually diagnose potential cancer. From the very first test, it performed with inspiring accuracy.
