SkinGun shoots burn victims with their own stem cells

Guns are often thought about for their destructive nature, but a new kind of gun is set to help heal rather than harm. Called the SkinGun, the device applies stem cells to the site of a burn in a novel way, helping increase both treatment and recovery time over standard methods. New tests show that it delivered a healing spray with 200 times more coverage than traditional methods.Read More

No more heart-in-a-backpack for Michigan man

In January 2015, then-24-year-old Stan Larkin left The University of Michigan Frankel Cardiovascular Center with an artificial heart in his chest and the pump that drove it on his back in a bag. Larkin was the first person to receive the completely artificial heart in Michigan and for a year, it kept him alive by pushing blood through his circulatory system. Now, Larkin has traded his backpack in for a real heart, having gotten a transplant last month.Read More

Latest bionic leaf now 10 times more efficient than natural photosynthesis

Over the last few years, great strides have been made in creating artificial leaves that mimic the ability of their natural counterparts to produce energy from water and sunlight. In 2011, the first cost-effective, stable artificial leaves were created, and in 2013, the devices were improved to self-heal and work with impure water. Now, scientists at Harvard have developed the "bionic leaf 2.0," which increases the efficiency of the system well beyond nature's own capabilities, and used it to produce liquid fuels for the first time.Read More

SpaceX raises prices to lower them

SpaceX has done so well in bringing down launch costs that it's raising its prices. That may seem paradoxical, but all is not what it seems. As well as making great strides towards its goal of a reusable launch system with three sea landings in a row, SpaceX has made improvements in rocket engine technology which mean that while launch prices look like they are going up, they're actually going down.Read More

Scientists break through the clouds to reveal source of Jupiter's wild weather

The standard image of Jupiter is of a mysterious planet shrouded in colorful strips, spots and swirls. But what exactly is going on beneath the atmosphere's chaotic exterior is a question that has mystified astronomers for some time. Researchers have now peeled back the curtain by producing the most detailed radio map of Jupiter's atmosphere yet, revealing swathes of ammonia gas that drive its stormy weather and possibly, other giant planets just like it.Read More

Tiny lasers on silicon means big things for electronics

Silicon forms the basis of everything from solar cells to the integrated circuits at the heart of our modern electronic gadgets. However the laser, one of the most ubiquitous of all electronic devices today, has long been one component unable to be successfully replicated in this material. Now researchers have found a way to create microscopically-small lasers directly from silicon, unlocking the possibilities of direct integration of photonics on silicon and taking a significant step towards light-based computersRead More

New Shepard's parachute set to fail on next flight in the interests of safety

Blue Origin Founder and CEO Jeff Bezos has revealed that when the New Shepard suborbital launch system takes to the skies later this month, the unmanned crew capsule won't come floating gently back to Earth. Instead, like a series of tests conducted by NASA on the Orion space capsule, the flight engineers plan to create a controlled parachute failure to test the emergency systems designed to protect the crew in the event of such a scenario.Read More

​Virus "delivery trucks" flip disease-causing cells into healthy ones

It sounds like a scene from a sci-fi movie: Scientists create a weapon that neutralizes a bad invading entity and maybe even turns it into a force for good. That's a bit like what researchers at the University of California San Francisco (UCSF) have just done. Only in this case, the invaders are disease-causing liver cells and the "weapon" involves a bit more than special effects.Read More

What do Pluto's heart and a lava lamp have in common?

Using data captured by NASA's New Horizons spacecraft, a team of researchers from Purdue University (PU) has estimated the depth of the vast nitrogen ice pool believed to exist beneath the Sputnik Planum region on the dwarf planet Pluto. Located in the dwarf planet's heart-shaped feature, the region is thought to continuously refresh its surface through a process known as convection.Read More

Stem cell treatment reawakens limbs in wheelchair-bound stroke victim

While new tools have emerged to help rehabilitation along, the road back to a healthy life after suffering a stroke can be a long and challenging one. In research that could one day significantly cut recovery times for victims of these debilitating brain injuries, scientists have injected modified stem cells into the brains of patients and brought about substantial improvements to motor function, with one even regaining control of her limbs and leaving her wheelchair behind.
