Digging for DNA: Ancient genomes can illuminate the past and reframe the present

by Aparna Nathan figures by Abagail Burrus Superheroes aren’t the only ones with riveting origin stories. As humans, where did we come from? How did we populate six continents? For hundreds of years, archaeology has tried to provide the answers by digging up artifacts and piecing together their histories.

‘Double-sided tape’ could replace surgical stitches

Sutures are commonly used to close wounds in the skin or other tissues. Similar to sewing fabric, the doctors will use a needle attached to a thread to penetrate the tissue and close the edges of the wound together, facilitating quick healing. Although surgical sutures have been used for thousands of years, they still have some limitations: 1) the needles cause some damage to the … Continue reading ‘Double-sided tape’ could replace surgical stitches

Brain-machine interfaces may be used to study and regulate mood

Brain-machine interfaces translate brain signals into information that can be used to control robotic limbs, and now even predict an individual’s mood state. Researchers envision using BMIs together with electrical stimulation, to regulate abnormal brain signals in patients with treatment-resistant neuropsychiatric disorders.
