3D printed corals grow algae that photosynthesize more efficiently

Central to coral reefs around the world is the deeply interdependent relationship between corals and algae. This interconnection is responsible for algae’s protected habitat, corals’ bright colors, and the mutual exchange of nutrients for photosynthesis. Algae growth is modulated by a process called self-shading, decreasing exposure to light. In an artificial setup, however, this process prevents researchers from growing coral quickly. To prevent this light … Continue reading 3D printed corals grow algae that photosynthesize more efficiently

‘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. Continue reading Brain-machine interfaces may be used to study and regulate mood
