Scientists have been experimenting with ways to feed humans in space. But that same technology could be put to use on Earth, where food shortages are already a real problem across the globe. NASA has taken up the challenge, using technology to speed breed six generations of crops each year.

The work is being done at the John Innes Centre, where scientists are going well beyond the annual production rate of two generations of crops. By being able to triple crop production, scientists believe they’ll able to fast-track developments like greater resistance to disease and global warming. They’ll also be able to produce a higher volume of crops to help reduce the food insecurities in various areas.

It’s only a matter of time before technology is able to restore vision to those who are completely blind. But some improvement is coming sooner than you think, thanks to Bionic Vision Technologies. During a trial, four Australian patients who had suffered significant vision loss due to degenerative Retinitis Pigmentosa saw notable improvement.

Prior to the trial, the four participants could sense light and dark, but they were unable to even detect a hand moving in front of them. Researchers implanted bionic eyes and the patients could detect objects around them in grayscale, which meant they could navigate without the use of guide dogs or a walking stick.

As of a way of demonstrating what the next generation will deal with, the Global Grad Show showcases innovative projects from some of the world's finest technology and design schools.

This year's edition included 150 inventions that are likely to impact the future. Some have been executed on a small scale and are relatively simple, while others rely on a complex mix of high-tech and virtual. A few of the featured projects:

According to a University of Tennessee researcher, human remains found on an isolated South Pacific island appear to be those of famed American aviator Amelia Earhart, whose plane disappeared while she was trying to circumnavigate the globe with her navigator, Fred Noonan.

Richard Jantz, professor emeritus of anthropology and director emeritus of the university's Forensic Anthropology Center, decided to take another look at seven bone measurements conducted in 1940 by physician D. W. Hoodless, who determined that the bones were those of a human male.

Jantz implemented a handful of scientific techniques such a computer program called Fordisc that can gauge ancestry, gender, and stature from skeletal measurements. In so doing, Jantz concluded that Hoodless had arrived at a mistaken assignment of gender for the remains. Jantz co-created the Fordisc program, used by board-certified forensic anthropologists the world over.

Organ transplant recipients spend the days following their operations worrying that their bodies will reject the new organ. But a new type of immunotherapy created by a team at Mount Sanai could reduce that risk. The therapy relies on nanotechnology, which can target the cells that initiate the immune response that leads to the organ rejection.

The rejection happens when the myeloid cells activate T-cells that attack the new organ. The medical community is already aware of this process, which is why organ transplants now take drugs that suppress that immune response. Unfortunately, those drugs can put patients at risk for infection and cancer.
