To better capture a true crime scenario and examine false memories that arise from external sources, the research team used virtual reality (VR). In one simulation, the participants witnessed a fight unfolding on a train station platform, and in a second, the volunteers (while in VR) stole a handbag from someone at a bar. Half of the participants took cannabis before donning their VR gear, while the other half remained sober. … [Read more...] about Getting high on cannabis makes people vulnerable to ‘false memories’
Commercial beekeepers feed bees high fructose corn syrup instead of honey for the same reason that commercial food manufacturers feed it to us: it’s cheaper. But it's only one of the problems the bees face. In the 1980s the varroa mite, Varroa destructor, started attacking bees in the US, so pesticides were introduced into beehives to kill the mites. This research suggests that swapping out honey robbed the bees of things they need to rev up their detoxification systems just when they needed it most—as they were exposed to an increased load of both pathogens and pesticides. … [Read more...] about Feeding bees corn syrup may leave them vulnerable to colony collapse
An obvious barrier to lucid dreaming is that lucid dreams aren't common. While most people have had a lucid dream at some point, the average person will have fewer than 10 in their lifetime, Arthuro said. One of the reasons so little research has been done on lucid dream therapy is that researchers are still exploring the most effective ways to induce lucid dreams. For instance, researchers reported in 2014 that using certain frequencies of electrical stimulation can increase the likelihood of a dreamer becoming aware that they're dreaming. … [Read more...] about Can you ‘turn off’ a nightmare?
Brian Acton doesn't hide his ambition that Signal could, in fact, grow into a WhatsApp-sized service. After all, Acton not only founded WhatsApp and helped it grow to billions of users, but before that joined Yahoo in its early, explosive growth days of the mid-1990s. He thinks he can do it again. "I’d like for Signal to reach billions of users. I know what it takes to do that. I did that," says Acton. "I’d love to have it happen in the next five years or less." … [Read more...] about Signal is finally bringing its secure messaging to the masses
The researchers started by showing that the same is true in insects. Initially, they worked with everyone's favorite fruit fly, Drosophila, showing that the equivalent genes responded in the same ways in the flies. They then showed that the innate immune response isn't activated when these same flies are exposed to an infection. A different class of insecticide (an organophosphate) had a much weaker effect on the fly's innate immunity. With the molecular activity well characterized, they went on to demonstrate that the same effects could be seen in bees. … [Read more...] about An insecticide-infection connection in bee colony collapses
