A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month. Participants who experienced the greatest increase in flexible, varied brain activity also reported more pe…

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering functi…

For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is generally safe…
