A team of researchers at the A*STAR Institute of Materials Research and Engineering has developed a new self-assembled nanoparticle which acts as a safe fluorescent probe, used to generate 3-D pictures of cancer cell structures in living tissue. Two-photon microscopy (TPM) uses […]
The long held belief that women are better multitaskers than men seems to finally be debunked, according to a new Swedish study. “On the contrary, the results of our study show that men are better at multitasking than women,” Timo Maentylae, a psychology professor at Stockholm University, said. Surprising or not, the female ability to […]
Some people never forget a face, some people do it all the time; and then there’s the people who actually can’t differentiate between one face and another, suffering from a condition called facial blindness. For the first time, researchers have managed to pinpoint two places in the brain (in the fusiform gyrus) which are responsible […]
Strangely enough, it was computer simulation that provided the mathematical support for the grandmother hypothesis – a famous yet controversial theory which suggests adult humans have longer lifespans as a result of grandmother babysitting. Longevity genes The simulation indicates that without any estimate of the brain size, an animal with a chimp-like lifespan can evolve […]
The pyramids, art, all of the world’s great inventions, literary works, just about any valuable intellectual work can be traced back to food – cooked food. If you care to go as far back as our very roots, that is. Previous research showed that cooked food made it easier and more efficient for our guts to […]
A while ago I reported about one of the most astonishing medical stories, when Richard Lee Norris, a terribly disfigured young male, received the most comprehensive face transplant in history. During the procedure, both jaws, teeth, facial soft tissue from the scalp to the neck and sensory muscles indispensable to facial expression were replaced. After seven […]
Green tea has some absolutely remarkable properties: it has a swarm of antioxidants, it is good for preventing a huge number of diseases (including some cancers), it boosts the immune system and it also helps you lose weight.
