Spinal Cord Injury and Stem Cells
Every year, 15,000 – 20,000 Americans sustain a spinal cord injury (SCI). Another 200,000 – 500,000 are living in the chronic stages of SCI every day. Loss of movement and sensation, persistent pain, and depression are common. Could stem cells play a role in finding a cure? Dr. Mark Tuszynski shares his work using neural […]

Scenes of spaceships hopping from one galaxy to the next are so common, it seems almost inevitable that future generations will one day vacation on Mars. But, if we are ever going to achieve life on other planets, we first have to figure out […]

Engineering Mosquitos to Fight Malaria
Mosquitos are the deadliest animal on Earth. They spread diseases like yellow fever, chikungunya, West Nile virus and malaria. Malaria alone killed 435,000 people and infected another 219 million in 2017 according to the World Health Organization. There are widespread efforts to combat mosquito-borne illnesses, including revolutionary new gene editing techniques. Ethan Bier and Valentino […]
