Today's CO2 may become tomorrow's concrete

As carbon emissions continue to rise and cause the planet to warm up, we need to find ways to reduce them. Capturing carbon at the source of its emission is one of the solutions, but there is still the problem of storing all the carbon sucked out of the atmosphere. If that captured carbon could be put to good use, then perhaps we could have the perfect capturing system in place. This is the line of thinking that researchers at University of California (UCLA) are currently pursuing, and they have some big plans for all that carbon: turning it into concrete.Read More

Research says BPA replacement in plastics not safer

The BPA-free trend started after studies found a link between bisphenol A (BPA) and health issues such as early puberty and prostate cancers. After that, products with bisphenol S (BPS) started cropping up as a safer alternative. But now a UCLA-led study suggests that BPS can be just as harmful as BPA, causing faster embryonic development and disruption of the reproductive system in animals.

Magnesium and silicon carbide recipe results in lightweight metal with record strength

Magnesium has a number of potential advantages when it comes to engineering. It is considered the lightest of structural metals and it is the eighth most abundant element in the Earth's crust. On the flipside, however, it is not as strong and durable as some of its counterparts. Scientists are now reporting to have overcome its main limitations by infusing it with silicon carbide nanoparticles to form a new type of super-strong composite material, which they claim may lead to lighter and more efficient airplanes, spacecraft and cars.

New hydrogel aids skin regeneration to improve wound healing

Healing chronic skin wounds can be difficult, particularly when they span large areas, or when healing is complicated by health problems such as a lack of mobility. A team of researchers from the University of California, Los Angeles (UCLA) has worked to improve the process, creating a more effective method of regeneration through use of a new material that creates a porous scaffold, allowing wounds to heal more effectively.Read More

Completely paralyzed man steps out in robotic exoskeleton

Working with a team of UCLA scientists, a man with protracted and complete paralysis has recovered sufficient voluntary control to take charge of a bionic exoskeleton and take many thousands of steps. Using a non-invasive spinal stimulation system that requires no surgery, this is claimed to be the first time that a person with such a comprehensive disability has been able to actively and voluntarily walk with such a device.Read More

Non-invasive spinal cord stimulation gets paralyzed legs moving voluntarily again

Five men with complete motor paralysis have regained the ability to move their legs voluntarily and produce step-like movements after being treated with a non-invasive form of spinal cord stimulation. The new treatment builds on prior work to generate voluntary movements in paralyzed people through electrical stimulation – in particular, two studies (one completed in 2011, the other in 2014) that involved surgically implanting an electrode array on the spinal cord. This time, however, the researchers found success without performing any invasive surgery.Read More

New dimensions of quantum information added through hyperentanglement

In quantum cryptography, encoding entangled photons with particular spin states is a technique that ensures data transmitted over fiber networks arrives at its destination without being intercepted or changed. However, as each entangled pair is usually only capable of being encoded with one state (generally the direction of its polarization), the amount of data carried is limited to just one quantum bit per photon. To address this limitation, researchers have now devised a way to "hyperentangle" photons that they say can increase the amount of data carried by a photon pair by as much as 32 times.Read More
