Detecting radioactive material from afar

New method developed by UMD researchers could be scaled up to improve security at ports of entry Physicists at the University of Maryland have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the material, the new technique

Higher-density aviation biofuel made from plant waste and timber harvesting can increase aircraft range

Scientists in China have developed a process for converting plant waste from agriculture and timber harvesting into high-density aviation fuel. Their research, published March 21 in the journal Joule, may help reduce CO2 emissions from airplanes and rockets. Cellulose, the main component in the biofuel, is a cheap, renewable, and highly abundant polymer that forms the

4D printed shape programming materials can be as stiff as wood or as soft as a sponge

Rutgers engineers’ unique smart materials change shape as temperatures change Rutgers University–New Brunswick engineers have created flexible, lightweight materials with 4D printing that could lead to better shock absorption, morphing airplane or drone wings, soft robotics and tiny implantable biomedical devices. Their research is published in the journal Materials Horizons. 3D printing, also known as

First inexpensive ankle exoskeleton that could be worn under clothes without restricting motion

A new lightweight, low-profile and inexpensive ankle exoskeleton could be widely used among elderly people, those with impaired lower-leg muscle strength and workers whose jobs require substantial walking or running. Developed by Vanderbilt mechanical engineers, the device is believed to be the first ankle exoskeleton that could be worn under clothes without restricting motion. It

New monitor watches the behavior of all electric devices within a building, ship, or factory

Sensor can monitor wiring in a building or ship, and signal when repairs are needed. A new system devised by researchers at MIT can monitor the behavior of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an

A new energy efficient process removes nearly all traces of oil in produced water

About 2.5 billion gallons of produced water, a byproduct from the oil refinery and extraction process, is generated each day in the United States. Handling that water is a major challenge in the oil refinery industry, particularly because it is deemed unusable for household and commercial use by the Environmental Protection Agency because of remaining contaminants. Several

An adhesive gel could repair injuries without surgery

An adhesive gel packed with light-activated chemicals can seal cuts or ulcers on the cornea —the clear surface of the eye — and then encourage the regeneration of corneal tissue, according to a preclinical study published online today in Science Advances. The new technology, named GelCORE (gel for corneal regeneration), could one day reduce the need for

A textile-based wearable display technology that is washable and needs no external power

When we think about clothes, they are usually formed with textiles and have to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a KAIST research team, who developed

Neural networks can be designed by artificial intelligence up to 200 times faster

Kicking neural network design automation into high gear A new area in artificial intelligence involves using algorithms to automatically design machine-learning systems known as neural networks, which are more accurate and efficient than those developed by human engineers. But this so-called neural architecture search (NAS) technique is computationally expensive. A state-of-the-art NAS algorithm recently developed

DNA molecules that can carry out reprogrammable computations, for the first time

Computer design meets potions class: A little of vial 1 and a little of vial 2 yield six-bit computations encoded in DNA Computer scientists at Caltech have designed DNA molecules that can carry out reprogrammable computations, for the first time creating so-called algorithmic self-assembly in which the same “hardware” can be configured to run different

A simple new technique can detect fake drugs from a video taken as the sample undergoes a disturbance 

“Chronoprints” can identify a sample from a video taken as it reacts to disturbance If we could tell authentic from counterfeit or adulterated drugs and foods just by looking at them, we could save money and lives every year, especially in the developing world, where the problem is worst. Unfortunately, the technologies that can detect

Nanoparticle robots start to come together as ‘gray goo’

Researchers create new kind of robot composed of many simple particles with no centralized control or single point of failure The concept of “gray goo,” a robot comprised of billions of nanoparticles, has fascinated science fiction fans for decades. But most researchers have dismissed it as just a wild theory. Current robots are usually self-contained
