Because light travels far faster than sound, we see distant events before we hear them. Perhaps as a child you learned to count the seconds between a lightning flash and the sound of thunder to estimate its distance. 

A new paper says that our brains can also detect and process sound delays that are too short to be noticed consciously. And they found that we use even that unconscious information to fine tune what our eyes see when estimating distances to nearby events. 

In a new study, infants remained calm twice as long when listening to a song as when listening to speech. The study involved thirty healthy infants aged between six and nine months.

Humans like music biologically, according to one hypothesis. In adults and older children, this "entrainment" may be displayed by behaviors such as foot-tapping, head-nodding, or drumming. 

"Emotional self-control is obviously not developed in infants, and we believe singing helps babies and children develop this capacity," says Professor Isabelle Peretz of the  University of Montreal. 

In the film version of "The Martian", the main character is trapped on the red planet and is forced to figure out how to grow food. He declares he is going to "science the s--t out of" the issue before instead engaging in regular old agriculture mixed with some engineering.

But science may soon help, researchers have discovered a gene that could open the door for space-based food production. Professor Peter Waterhouse, a plant geneticist at QUT, discovered the gene in the ancient Australian native tobacco plant Nicotiana benthamiana, known as Pitjuri to indigenous Aboriginals tribes, which has been used for decades as a model plant upon which to test viruses and vaccines.

Want to be an athlete but think it is too much work?

Psychoactive drugs may be the answer.

Let's face it, exercise is a lot of work. Our ancestors worked all of the time and they lived to be 35 so we have clearly evolved to be lazy. Effort is the largest barrier to why people do not exercise so Professor Samuele Marcora at University of Kent suggests that reducing perception of effort during exercise using caffeine or other psychoactive drugs (e.g. methylphenidate and modafinil) could help many people stick to their fitness plans. By fooling them into thinking it is less effort than it is.

Products like milk have been fortified with Vitamin D for decades because of its importance in uptake of calcium in the bones, along with other cellular and immune processes. The body creates vitamin D in the form of cholecalciferol within the skin itself, if there is a sufficient amount of sunlight. 

A new survey reveals that couples enjoyed more frequent and satisfying sex for both partners when men made a fair contribution to housework. The same paper also says there's no relationship between the amount of housework male partners completed and the sexual functioning of a couple.
