Berkeley Lab Builds ‘Artificial Forest’ to Harvest Solar Energy
by dailyfusion in The Daily Fusion
Devices for artificial photosynthesis are often called “artificial leaves”. This leaves, however, are of no use unless you can create an “artificial forest” from them. Now, scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory have reported the first fully integrated nanosystem for artificial photosynthesis.... Read more »

Even People Without Synesthesia Find Colors in Music
by Elizabeth Preston in Inkfish
It’s time to stop scoffing at the synesthetes: linking music to colors is totally normal. It’s not really about the notes, though. Researchers say the colors we find in music are actually the colors of the emotions the music makes us feel.
Synesthetes are people whose sensory experiences overlap; they most often link letters or numbers to certain colors. Music-color synesthesia, in which hearing music triggers the colors, is rarer. In fact, when Stephen Palmer and Karen Schloss at the........ Read more »

Major Advance For Stem Cell Research
by Perikis Livas in Tracing Knowledge
Scientists at Oregon Health & Science University and the Oregon National Primate Research Center (ONPRC) have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any other cell type in the body. It is believed that stem cell therapies hold the promise of replacing cells damaged through injury or illness. Diseases or conditions that might be treated through stem cell therapy include Parkinson’s disease, multiple sclerosis, cardiac disease a........ Read more »

Bright Lights, Cold Bodies - The Near-Death Experience Explained
by Anouk Vleugels in United Academics
Last February, Dr. Sam Parnia, an intensive care physician who has been researching near-death experiences for the past 15 years, published his new book ‘Erasing death: The Science That is Rewriting the Boundaries Between Life and Death’. Following the release of that book, Dr. Parnia was interviewed on National Public Radio in the US. It wasn’t so much this interview that sparked my interest, as much as the comments that followed. “It’s hard to believe that this gu........ Read more »

Does it take two to tango to get win-win negotiation outcomes?
by Alex Fradera in BPS Occupational Digest
Negotiation training has been shown to lead to positive outcomes for parties on both sides of the table, identifying 'win-win' solutions and helping the wheels of the world turn more amicably. But many studies focus on consequences when both negotiators are trained using the same methodology, when the reality is that a counterpart from another organisation may be trained differently or not at all. What happens then? A study by Alfred Zerres and colleagues finds out.The study recruited 360 busine........ Read more »

Scanning a brain that believes it is dead
by Christian Jarrett in BPS Research Digest
What is going on in the brain of someone who has the deluded belief that they are brain dead? A team of researchers led by neuropsychologist Vanessa Charland-Varville at CHU Sart-Tilman Hospital and the University of Liege has attempted to find out by scanning the brain of a depressed patient who held this very belief.
The researchers used a Positron Emission Tomography (PET) scanner, which is the first time this scanning technology has been used on a patient with this kind of delusion -........ Read more »

Something small has gone wrong in your home. Maybe a light bulb has gone out, or the tap has started leaking at the hinge. You can't fix it right now, because you're half way through watching nineties classic "Home Alone 2: Lost in New York". Or maybe "Game of Thrones". Whatever, I don't keep up with TV. The point is you need a quick fix, so you grab a lamp from the bedroom or stick a towel under the sink. That'll do, you think. I'll sort it out properly tomorrow.

Why don't men understand women?
by Isabel Torres in Science in the clouds
Men might have found themselves an excuse not to listen to women. New research suggests that men have twice more difficulty reading emotions in women than in men. This may not sound surprising, but evidence that men have trouble understanding women is, at best, scarce.Being able to guess someone else’s thoughts, feelings and intentions is an instinctive social skill that develops in early childhood. We might take it for granted, but people who struggle or are unable to read other people, like ........ Read more »

When green means danger A stunning new species of palm-pitviper from Honduras
by Perikis Livas in Tracing Knowledge
A new species of green palm-pitviper of the genus Bothriechis is described from a seriously threatened cloud forest reserve in northern Honduras. Because of similarity in color pattern and scalation, the new species (Bothriechis guifarroi) was previously confused with other Honduran palm pitvipers. Genetic analysis revealed that the closest relatives of the new species are actually found over 600 km to the south, in the mountains of Costa Rica. The study was published in the open access journal ........ Read more »
