Study shows how LSD interferes with brain's signaling | Science

A group of volunteers who took a trip in the name of science have helped researchers uncover how LSD messes with activity in the brain to induce an altered state of consciousness. chemical allows parts of the cortex to become flooded with signals that are normally filtered out to prevent information overload. The drug allowed more information to flow from …

Scientists design soft robot that creeps like the tendrils of the plant | robot | portable devices | osmosis | a soft robot | curl | climb

Scientists have developed a soft robot that can curl and climb like the plants, a step that can pave the way for changing portable devices. Scientists at the Istituto Italiano di Tecnologia (IIT) in Italy took inspiration from plants and their movement.

'Whisper' laser tech sends audible messages to specific people

The team started with a laser beam that fired at wavelengths absorbed by water. By sweeping the beam at the speed of sound, they found that it could be used to generate sound that can only be heard at a specific distance from the transmitter. That would allow a message to be sent to an individual, rather than just anyone …
