Freshwater from salt water using only solar energy
A federally funded research effort to revolutionize water treatment has yielded a direct solar desalination technology that uses energy from sunlight alone to heat salt water for membrane distillation. The technology could provide off-grid water treatment for some of the 1 billion people who lack access to clean water.

Why Do DMT Users See Insects from a Parallel Universe?
The molecule DMT (N,N-Dimethyltryptamine) is a psychoactive chemical that causes intense visions and can induce its users to quickly enter a completely different "environment" that some have likened to an alien or parallel universe. The transition from our world to theirs occurs with no cessation of consciousness or…

Closest Temperate World Orbiting Quiet Star Discovered
A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO’s unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be…

The hippocampus as a 'predictive map'
Think about how you choose a route to work, where to move house, or even which move to make in a game like Go. All of these scenarios require you to estimate the likely future reward of your decision. This is tricky because the number of possible scenarios explodes as one peers farther and farther into the future…

Can a Human See a Single Photon? (1996)
The human eye is very sensitive; but can we see a single photon? The answer is yes: sensors in the retina can respond to a single photon. But neural filters only allow a signal to pass to the brain to trigger a conscious response when at least about five to nine arrive within less than 100 ms. If we could consciously…
