Nanoparticles limit damage in spinal cord injury
After a spinal cord injury, significant secondary nerve damage is caused by inflammation and internal scarring that inhibits the ability of the nervous system to repair itself. A biodegradable nanoparticle injected after a spinal cord trauma prevented the inflammation and internal scarring that inhibits the repair process, reports a new study. Mice with a spinal cord injury receiving the nanoparticle injection were able to walk better after the injury than those that didn't receive it.

A revolution in lithium-ion batteries is becoming more realistic
The modern world relies on portable electronic devices such as smartphones, tablets, laptops, cameras or camcorders. Many of these devices are powered by lithium-ion batteries, which could be smaller, lighter, safer and more efficient if the liquid electrolytes they contain were replaced by solids. A promising candidate for a solid-state electrolyte is a new class of materials based on lithium compounds, presented by physicists from Switzerland and Poland.

European XFEL: Europe's next-generation free-electron laser
The European XFEL free-electron laser was inaugurated on Sept. 1, 2017, near Hamburg. By producing ultra-bright, trillion-photon X-ray flashes, this European instrument will allow scientists to map the atomic relief of viruses and even film chemical reactions. The French National Center for Scientific Research and Alternative Energies and Atomic Energy Commission both played a leading role in the design and construction of the superconducting electron accelerator at the heart of this international research facility.

Like a revolving door: How shuttling proteins operate nuclear pores
Nuclear pore complexes are tiny channels where the exchange of substances between the cell nucleus and the cytoplasm takes place. Scientists at the University of Basel report on startling new research that might overturn established models of nuclear transport regulation. Their study published in the Journal of Cell Biology reveals how shuttling proteins known as importins control the function of nuclear pores -- as opposed to the view that nuclear pores control the shuttling of importins.

UMass Amherst environmental chemist flashes warning light on new nanoparticle
The UMass Amherst and Chinese research team found that layered BP's cytotoxicity is based on the fact that it generates reactive oxygen species (ROS). ROS are among the most potent cell-damaging agents known. Layered BP also disrupts cell membrane integrity in a particle-size-dependent manner.

Acting like a muscle, nano-sized device lifts 165 times its own weight
New Brunswick engineers have discovered a simple, economical way to make a nano-sized device that can match the friendly neighborhood Avenger, on a much smaller scale. Their creation weighs 1.6 milligrams (about as much as five poppy seeds) and can lift 265 milligrams (the weight of about 825 poppy seeds) hundreds of times in a row.

Making 3-D printing safer
Within the past decade, 3-D printers have gone from bulky, expensive curiosities to compact, more affordable consumer products. At the same time, concerns have emerged that nanoparticles released from the machines during use could affect consumers' health. Now researchers report in ACS' Environmental Science & Technology a way to eliminate almost all nanoparticle emissions from some of these printers.

A low-cost method for solar-thermal conversion that's simpler and greener
Researchers at Columbia Engineering have developed a simple, low-cost, and environmentally sound method for fabricating a highly-efficient selective solar absorber (SSA) to convert sunlight into heat for energy-related applications. The team used a 'dip and dry' approach whereby strips coated with a reactive metal are dipped into a solution containing ions of a less reactive metal to create plasmonic-nanoparticle-coated foils that perform as well or better than existing SSAs, regardless of the sun's angle.

Solar hydrogen production by artificial leafs: Scientists analysed how a special treatment improves cheap metal oxide photoelectrodes
Metal oxides are promising candidates for cheap and stable photoelectrodes for solar water splitting, producing hydrogen with sunlight. Unfortunately, metal oxides are not highly efficient in this job. A known remedy is a treatment with heat and hydrogen. An international collaboration has now discovered why this treatment works so well, paving the way to more efficient and cheap devices for solar hydrogen production.

CWRU awarded funding to understand how plant particle stimulates anti-tumor response
Nicole Steinmetz, PhD, has received a major grant from the National Institutes of Health to help understand how a virus-like particle from plants stimulates potent anti-tumor responses. "This research is aimed at giving the body's own cancer-fighting capacity a major 'lift and push,'" said Steinmetz. "It also offers potential to fight cancer in dogs, who are of course members of our families as well. We are very grateful to the National Institutes of Health for supporting this potentially transformative work."
