When we hear our favorite music, our thoughts tend to shift inward, activating the default mode network (DMN) a network of brain regions that’s active when a person is awake but at rest. Our favorite songs also seem to spark a conection between our auditory circuts and the hippocampus, a region responsible for memory and emotions.
Inspired perhaps by Harry Potter’s invisibility cloak, scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view. The latest effort, developed at the University of Rochester, not only overcomes some of the limitations of previous devices, but it uses inexpensive, readily available materials in a novel configuration.
An American physicist claims she has mathematically refuted the existence of black holes in our universe. The new theory combines Steve Hawking’s radiation theory with quantum theory’s fundamental law that no information ever disappears from the universe. Professor Laura Mersini-Houghton from the University of North Carolina at Chapel Hill maintains she managed to merge two seemingly contradicting theories, Einstein’s theory of gravity and a fundamental law of quantum theory.
Altruism has posed a puzzle for psychologists and evolutionary biologists for centuries. Why is it that humans will help others even to their own detriment?
An on-and-off “switch” has been discovered in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. In our bodies, newly divided cells constantly. However, most human cells cannot divide indefinitely -– with each division, a cellular timekeeper at the ends of chromosomes shortens. When this timekeeper becomes too short, cells can no longer divide, causing organs and tissues to degenerate, as often happens in old age. But there is a way around this countdown, researchers have found.
Wolverine, Ghost Rider, the Incredible Hulk — all of these characters have at least one awesome trait in common: the ability to heal themselves. And now, the Pentagon wants to give ordinary people this superhuman capability.
Chemists from the University of Glasgow report in a new paper in Science today on a new form of hydrogen production which is 30 times faster than the current state-of-the-art method. The process also solves common problems associated with generating electricity from renewable sources such as solar, wind or wave energy.
Each GM human will be tiny – roughly the size of a microchip itself, simulating the response of humans to substances inhaled, absorbed in the blood, or exposed to in the intestinal tract.
A new dehydration system uses Earth’s energy field to solve rising damp problems, because it addresses the root cause by neutralizing the capillary forces. Besides drying walls of buildings, this system can also be used to dry out underground walls, basements, and cellars.
Dr Niraj Lal, of the Australian National University, found during his PhD at the University of Cambridge, that small nano-sized versions of Buddhist singing bowls resonate with light in the same way as they do with sound, and he’s applied this shape to solar cells to increase their ability to capture more light and convert it into electricity.
The shape of a centuries-old Buddhist singing bowl has inspired a Canberra scientist to re-think the way that solar cells are designed to maximize their efficiency.
For the first time ever, neuroscientists have demonstrated the viability of direct — and completely non-invasive — brain-to-brain communication in humans. Remarkably, the experiment allowed subjects to exchange mentally-conjured words despite being 5,000 miles apart.
When coffee leaves die and fall to the ground, they contaminate the soil with caffeine, which makes it difficult for other plants to germinate. Coffee may thus use caffeine to kill off the competition.
