3D-printed guide aids in complex nerve regeneration

Complex nerve injuries are a challenging problem for the medical fraternity, as their reattachment and regrowth is a fraught and delicate process that is very rarely successful. Overcoming these difficulties, however, would mean that a cure for debilitating conditions like paraplegia, quadriplegia and other forms of paralysis may one day be found. In this vein, US researchers have created the first-ever 3D printed guide specifically designed to assist in the regrowth of the sensory and motor functions of complex nerves.Read More

Fast radio bursts may provide 3D map of cosmos

Brief bursts of radio waves arriving from far-off galaxies could help astronomers estimate cosmological distances and piece together a 3D map of matter in the universe. If everything checks out, a new technique proposed by two cosmologists from the University of British Columbia will offer an independent metric – set apart from the uncertainties and systemic biases of existing methods – in plotting the large structures of the cosmos.Read More

Scientists use new catalysis method to boost biodiesel yields

Biofuels can be made from various source materials such as waste from the winemaking industry and woody biomass. Reseachers are also looking for new methods to improve its environmental credentials as there is still controversy as to how green biofuels really are. Now, a team at the Catalysis Institute at Cardiff University is hoping to make biofuel production more efficient and sustainable by recycling the leftovers from the process.Read More

Protein patch restores heart tissue and function after a heart attack

Though sufferers of heart attacks may survive the initial event, they cause permanent damage to the organ in the form of scar tissue, which affects its ability to pump blood. Scientists around the world are working on this problem, with hydrogels, human stem cells and even bioengineered tissue that sticks together like Velcro all offering possible solutions. But the latest promising advance comes from a team of researchers that has developed a simple protein patch that restores animal hearts almost to normal function.Read More

New technique bodes well for lung transplant success rate

Our bodies have developed a particularly unforgiving immune response when a threat is posed to our lungs. This is great for warding off infections and illness, though is something of a double-edged sword regarding transplants, with the recipient's body often perceiving the incoming organ as a threat and seeking to destroy it. But a new approach promises to boost the success rate of such procedures, by both repairing unhealthy donor lungs that wouldn't otherwise make the grade and reducing the chances of rejection once it is implanted.

New invisibility cloak hides tiny three-dimensional objects of any shape

Scientists at UC Berkeley have developed a foldable, incredibly thin invisibility cloak that can wrap around microscopic objects of any shape and make them undetectable in the visible spectrum. In its current form, the technology could be useful in optical computing or in shrouding secret microelectronic components from prying eyes, but according to the researchers involved, it could also be scaled up in size with relative ease.Read More

NASA's Orion spacecraft passes key review

NASA's Orion spacecraft has overcome its latest hurdle on the road to becoming human-rated, with the completion of a technical and programmatic review (TPR). Once finished, Orion will be the first spacecraft designed to allow astronauts to operate beyond Low-Earth Orbit (LEO) since the Apollo program. Eventually, NASA envisions using the capsule as a key component in the planned asteroid redirect mission, and the ongoing endeavor to one day put a man on Mars.Read More
