Dr. Oz has done a lot of things right recently.

Electronic devices that can be injected directly into the brain, or other body parts, have been a staple of science fiction for decades - and they seem a little closer to reality if you visit Charles Lieber's chemistry lab at Harvard. 

A team of international researchers, led by Lieber, has developed a method for fabricating nano-scale electronic scaffolds that can be injected via syringe. Once connected to electronic devices, the scaffolds can be used to monitor neural activity, stimulate tissues and even promote regenerations of neurons.  

In collaboration with the United States Department of Agriculture, the University of the Basque Country Department of Analytical Chemistry has identified the volatile compounds in damaged walnuts that insects find attractive and which is threatening the harvests of these nuts in California.

These are the first studies carried out on walnuts which are designed to specify the components of the aroma and which can be used to control the moth pests in the most sustainable way, besides helping to cut the use of pesticides and control agents. 

Food wasted means money wasted which can be an expensive problem especially in homes with financial constraints. A new study from the Cornell Food and Brand Lab and the Getulio Vargas Foundation, shows that the top causes of food waste in such homes include buying too much, preparing in abundance, unwillingness to consume leftovers, and improper food storage.

"Fortunately," notes lead author Gustavo Porpino, PhD candidate at the Getulio Vargas Foundation and Visiting Scholar at the Cornell Food and Brand Lab, "most of the factors that lead to food waste, can be easily remedied by simple changes in food buying, preparing, and storing."

Northern Ireland recently changed the law to criminalize the act of paying for sex. This follows a trend set in Sweden, where selling sex is legal but buying it is criminalized.

I’m on the back seat of the lower deck of a number 37 bus, outside the red-brick and Portland stone clock tower of Lambeth Town Hall in Brixton, south London.  Although I know exactly where I am, I feel lost. I no longer know whether to trust what my eyes are telling me.

I’ve just been told by a leading vision scientist that I have no real depth perception. 

In other words, I have never seen in three dimensions the way most people do.

Lisa Marie Potter, Inside Science - Thank goodness for autostabilization, the digital camera feature that compensates for movement to achieve that crystal-clear, spontaneous selfie.

Jurassic World brings to life the fantasy of an amusement park where genetically engineered dinosaurs are the main attraction, as first imagined in the original book, then movie Jurassic Park back in 1993. This fourth movie in the franchise, in cinemas from today, is certainly action-packed, although there are a number of opportunities missed when it comes to how these beasts are represented.

A new psoriasis drug, ixekizumab , has resulted in 40 percent of people showing a complete clearance of psoriatic plaques after 12 weeks of treatment and over 90 percent showing improvement.

A psychologist and an English professor have written a review of studies and concluded that pigs perform as well as or better than dogs on some tests of behavioral and cognitive sophistication, and they compare favorably to chimpanzees.

The review by Emory psychologist Dr. Lori Marino and visiting English Professor Christina M. Colvin, seeks to extrapolate results to deduce what we do and do not know about pigs. The areas they discuss include cognition, emotion, self-awareness, personality and social complexity.

They conclude that “pigs possess complex ethological traits similar … to dogs and chimpanzees.” For example, pigs:
