A team of multiple sclerosis (MS) experts led a pilot randomized controlled trial of robotic-exoskeleton assisted exercise rehabilitation (REAER) effects on mobility, cognition, and brain connectivity in people with substantial MS-related disability. Their results showed that REAER is likely an effective intervention, and is a promising therapy for improving the lives of those with MS.…

A team of researchers has discovered unexpectedly familiar behavior in the antiferroelectric material known as zirconium dioxide, or zirconia. Now, a team led by Georgia Tech researchers has discovered unexpectedly familiar behavior in the antiferroelectric material known as zirconium dioxide, or zirconia. They show that as the microstructure of the material is reduced in size,…

The dark skin pigment melanin protects us from the sun’s damaging rays by absorbing light energy and converting it to heat. This could make it a very effective tool in tumor diagnosis and treatment. Scientists managed to create melanin-loaded cell membrane derived nanoparticles, which improved tumor imaging in an animal model while also slowing the…

3D printers may one day become a permanent fixture of the operating theatre after scientists showed they could print bone-like structures containing living cells. Using a 3D-printer that deploys a special ink made up of calcium phosphate, the scientists developed a new technique, known as ceramic omnidirectional bioprinting in cell-suspensions (COBICS), enabling them to print…

The Hall thruster is a propulsion system that is often used by spacecraft engaged in longer missions. A recent study has shown how the operating lives of these systems can be further extended. The speed or direction of a spacecraft operating in a vacuum can be changed using an ion drive, which creates thrust by…

The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Scientists modeled the mixing of materials associated with these impacts, revealing that the Red Planet may have formed over a longer timescale than previously thought.…

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider than conventional ones, and can detect radio waves emitted by many types of molecules in space at once. This is expected to enable significant…

A new method could allow better materials to make up battery electrodes by converting them into a nanochain structure, extending battery lifetime and increasing stability. Materials with a higher lithium ion storage capacity are either too heavy or the wrong shape to replace graphite, the electrode material currently used in today’s batteries. Purdue University scientists…

A team has developed a new method of printing and sintering a variety of solid-state electrolyte thin films called ‘printing and radiative heating.’ A research team led by Liangbing Hu at the University of Maryland’s A. James Clark School of Engineering recently developed a new method of printing and sintering a variety of SSE thin…

Researchers have used excited-state electron transfer events to ‘pump’ olefin molecules up and then have them fall back down through a series of favorable steps to ultimately transform into a less stable isomeric form. This essentially allows internal olefins, or alkenes, to migrate along the carbon chain to the terminal position — a kind of…
