In the movie “Transformers,” cars morph into robots, jets or a variety of machinery. A similar concept inspired a group of researchers to combine gas foaming, which is a blend of chemicals that induces gas bubbling, and 3D molding technologies to quickly transform electrospun membranes into complex 3D shapes for biomedical applications.

In Applied Physics Reviews, the group reports on its new approach that demonstrates significant improvements in speed and quality compared with other methods. The work is also the first successful demonstration of formation of 3D neural constructs with an ordered structure through differentiation of human neural progenitor/ on these transformed 3D scaffolds.

“Electrospinning is a technology to produce nanofiber membranes,” said co-author Jingwei Xie, at the University of Nebraska Medical Center. “The physics principle behind it involves applying an electrical force to overcome the surface tension of a solution to elongate a solution jet into continuous and ultrafine fibers after solvent evaporation.”

The Woodward effect, also referred to as a Mach effect, is part of a hypothesis proposed by James F. Woodward in 1990.[1] The hypothesis states that transient mass fluctuations arise in any object that absorbs internal energy while undergoing a proper acceleration. Harnessing this effect could generate a reactionless thrust, which Woodward and others claim to measure in various experiments.[2][3]

Hypothetically, the Woodward effect would allow for field propulsion spacecraft engines that would not have to expel matter. Such a proposed engine is sometimes called a Mach effect thruster (MET) or a Mach Effect Gravitation al Assist (MEGA) drive.[4][5] So far, experimental results have not strongly supported this hypothesis,[6] but experimental research on this effect, and its potential applications, continues.[7]

The Space Studies Institute was selected as part of NASA’s Innovative Advanced Concepts program as a Phase I proposal in April 2017 for Mach Effect research.[8][9][10][11] The year after, NASA awarded a NIAC Phase II grant to the SSI to further develop these propellantless thrusters.[12][13].

Circa 2017

Injecting DNA into injured horse tendons and ligaments can cure lameness, new research involving scientists at Kazan Federal University, Moscow State Academy and The University of Nottingham has found.

The gene therapy technology was used in horses that had gone lame due to injury and within two to three weeks the horses were able to walk and trot. Within just two months they were back to full health, galloping and competing.

The study has big implications not just for the veterinary world but the future of human medicine — injuries like these are common in people as well as animals, not just in lameness but in other illnesses and diseases from the legs and arms through to the back and hips.

Quantum technology is currently one of the most active fields of research worldwide. It takes advantage of the special properties of quantum mechanical states of atoms, light, or nanostructures to develop, for example, novel sensors for medicine and navigation, networks for information processing and powerful simulators for materials sciences. Generating these quantum states normally requires a strong interaction between the systems involved, such as between several atoms or nanostructures.

Until now, however, sufficiently strong interactions were limited to short distances. Typically, two systems had to be placed close to each other on the same chip at low temperatures or in the same vacuum chamber, where they interact via electrostatic or magnetostatic forces. Coupling them across larger distances, however, is required for many applications such as quantum networks or certain types of sensors.

A team of physicists, led by Professor Philipp Treutlein from the Department of Physics at the University of Basel and the Swiss Nanoscience Institute (SNI), has now succeeded for the first time in creating strong coupling between two systems over a greater distance across a room temperature environment. In their experiment, the researchers used laser light to couple the vibrations of a 100 nanometer thin membrane to the motion of the spin of atoms over a distance of one meter. As a result, each vibration of the membrane sets the spin of the atoms in motion and vice versa.

No one has ever seen any airplane like this, except on computer animation. Now, some of the world’s top aeronautical engineers are going to build it for real.

The plan calls for constructing a six-ton unmanned, remote controlled plane the size of a business jet with 24 spinning propellers embedded in its huge moveable wings that allow it to magically hover in midair.

It’s an experimental airplane they call LightningStrike.
