Can we edit the content of our memories? It’s a sci-fi-tinged question that Steve Ramirez and Xu Liu are asking in their lab at MIT. Essentially, the pair shoot a laser beam into the brain of a living mouse to activate and manipulate its memory. In this unexpectedly amusing talk they share not only how, but — more importantly — why they do this.

Jonathan Webb looks at how we can switch our brains on and off and if we can switch off genetic illnesses.
Scientists from the University of Pittsburgh School of Medicine have successfully grown a working heart in a petri dish using the frame of a mouse’s heart and adult human skin cells, reverted back into their basic stem cell state. The heart works fully but beats at only half the speed of a full human heart — as well as obviously being too small. However, the breakthrough is the latest in a long line of developments which could revolutionise organ transplants.
The French magazine ’60 Million Consumers’ tested ten high protection sun creams on adults and children.

So the results are clear: some creams offer less protection than they advertise.

You can’t help it; sometimes, you just get a bad feeling about someone that’s hard to shake. So, what’s happening in your brain when you make that critical (and often lasting) first judgment?

People got medicine from nature, mostly from plants. In fact, botany, the study of plants, started out as an arm of medicine. To this day, many people around the world still get their medicine from plants.

Peek, a new app developed by researchers at the School of Tropical Medicine in London, could help tens of millions of people suffering blindness and sight problems in the developing world, by allowing opticians to visit remote corners of the world and perform eye tests using only a smartphone, then sending the results back to a central hospital for analysis.
The more time you spend on Facebook, the unhappier you become. That’s the not-so-astounding finding of the first study measuring the social network’s impact on users’ psychological well-being. And (surprise, surprise) the survey finds that interacting with people “directly” – you know, face-to-face, or over the phone – actually makes you happier. A team of […]
Russell Foster is a circadian neuroscientist: He studies the sleep cycles of the brain. And he asks: What do we know about sleep? Not a lot, it turns out, for something we do with one-third of our lives. In this talk, Foster shares three popular theories about why we sleep, busts some myths about how much sleep we need at different ages — and hints at some bold new uses of sleep as a predictor of mental health.
