Most Americans don’t have enough assets to withstand 3 months without income

A new study from Oregon State University found that 77% of low- to moderate-income American households fall below the asset poverty threshold, meaning that if their income were cut off they would not have the financial assets to maintain at least poverty-level status for three months. The study compared asset poverty rates in the U.S.

Russian state successfully flight tests 3D printed gas turbine engine

The Russian state-backed Advanced Research Foundation (FPI) and Federal State Unitary Enterprise (VIAM) have flight-tested their 3D printed MGTD-20 gas turbine engine for the first time. The motor was evaluated onboard a light Unmanned Aerial Vehicle (UAV), which was launched over the Kazanbash aviation center in Tatarstan, around 500 miles east of Moscow. Utilizing 3D

Enhanced water repellent surfaces discovered in nature

Through the investigation of insect surfaces, Penn State researchers have detailed a previously unidentified nanostructure that can be used to engineer stronger, more resilient water repellent coatings. The results of this research were published today (July 17) in Science Advances. With an enhanced ability to repel droplets, this design could be applied to personal protective

5G wireless networks have few health impacts, finds study using zebrafish model

Findings from an Oregon State University study into the effects of radiofrequency radiation generated by the wireless technology that will soon be the standard for cell phones suggest few health impacts. Fifth generation or 5G wireless technology, which began being deployed worldwide in 2019, provides faster connectivity and more bandwidth, meaning higher download speeds. But

Crystal structure discovered almost 200 years ago could hold key to solar cell revolution

Solar energy researchers at Oregon State University are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago. Not all materials with the structure, known as perovskites, are semiconductors. But perovskites based on a metal and a halogen are, and they hold tremendous potential as photovoltaic cells that could be

Jellyfish-inspired soft robots can outswim their natural counterparts

Engineering researchers at North Carolina State University and Temple University have developed soft robots inspired by jellyfish that can outswim their real-life counterparts. More practically, the new jellyfish-bots highlight a technique that uses pre-stressed polymers to make soft robots more powerful. “Our previous work focused on making soft robots that were inspired by cheetahs —

Teaching physics to neural networks removes ‘chaos blindness’

Researchers from North Carolina State University have discovered that teaching physics to neural networks enables those networks to better adapt to chaos within their environment. The work has implications for improved artificial intelligence (AI) applications ranging from medical diagnostics to automated drone piloting. Neural networks are an advanced type of AI loosely based on the

Quantum physics: Physicists develop a new theory for Bose-Einstein condensates

Bose-Einstein condensates are often described as the fifth state of matter: At extremely low temperatures, gas atoms behave like a single particle. The exact properties of these systems are notoriously difficult to study. In the journal Physical Review Letters, physicists from Martin Luther University Halle-Wittenberg (MLU) and Ludwig Maximilian University Munich have proposed a new

Scientists investigate directly 3D printing tissues within the body using robotics

A group of researchers from the Terasaki Institute for Biomedical Innovation, Ohio State University and Pennsylvania State University have developed a specially-formulated bio-ink designed for 3D bioprinting tissue directly in the body. The team embarked upon the project in order to overcome the drawbacks of in vitro tissue engineering procedures, which poses increased risks to
