Scientists have used an unconventional technique to increase the happiness of married couples: brain washing them with pictures of cute puppies. The team developed a procedure that could be used as part of marriage counselling to improve people’s feelings about their partners. The intervention could be used to keep the spark alive in long-distance and

Humans are the only ultrasocial creature on the planet. We have outcompeted, interbred or even killed off all other hominin species. We cohabit in cities of tens of millions of people and, despite what the media tell us, violence between individuals is extremely rare. This is because we have an extremely large, flexible and complex

 For the first time, conjoined twins Abby and Erin Delaney can sleep in separate beds. The 10-month-old girls from North Carolina were born connected at the head, an extremely rare condition.   Following months of planning and preparation, the pair underwent a successful 11-hour separation surgery last week at Children’s Hospital of Philadelphia in southeastern Pennsylvania, according to the hospital.

It’s a question that’s been bothering humans for centuries, even before the theory of evolution was first conceived. Why do men and other male mammals have nipples if they don’t feed their young? What’s the point? “I have received more than a dozen requests to explain how evolution could possibly produce such a useless structure,”

The belief that there is a link between talent and left-handedness has a long history. Leonardo da Vinci was left-handed. So were Mark Twain, Mozart, Marie Curie, Nikola Tesla, and Aristotle. It’s no different today – former US president Barack Obama is a left-hander, as is business leader Bill Gates and footballer Lionel Messi. But is

1. The impossible EM drive… works? Since first hearing rumours about NASA’s physics-breaking propulsion system late last year, a paper describing their device has passed peer-review, and China claims to be testing their own version in space right now. And yet, no one can explain how this fuel-less drive is able to violate Newton’s Third Law:

For every ten people hit by lightning, nine will survive. But what are the lasting effects of being exposed to hundreds of millions of volts? Sometimes they’ll keep the clothing, the strips of shirt or trousers that weren’t cut away and discarded by the doctors and nurses.   They’ll tell and retell their story at

Scientists studying the pattern of circadian rhythms have found that one central body clock could be controlling several others at the same time. By examining fruit flies – which, like humans, have several circadian clocks affecting the rhythm their daily biological processes – researchers have found evidence of a single ‘master’ clock that leads all other internal clocks related

Changing your meal times could be enough to reset one of your internal body clocks, researchers have found, giving us new insight into the relationship between when we eat and our body’s circadian rhythms. While previous studies have spotted a connection between nutrition, metabolism, and circadian rhythms in the human body, this new research pins

There are a lot of weird words you learn to pronounce and spell if you pay much attention to health, science and the environment. By the time Iceland’s spectacular volcanic eruption simmered down in 2010, for instance, “Eyjafjallajokull” was as familiar as “Mount Etna”. You should hear “Papahanaumokuakea” roll off the tongue of Juliet Eilperin, who

Perhaps one of the most intriguing and interesting phenomena in quantum physics is what Einstein referred to as a “spooky action at a distance” – also known as quantum entanglement. This quantum effect is behind what makes quantum computers work, as quantum bits (qubits) generally rely on entanglement to process data and information. It’s also the working theory

1. Lungs don’t just facilitate respiration – they also make blood. Mammalian lungs produce more than 10 million platelets (tiny blood cells) per hour, which equates to the majority of platelets circulating the body. 2. It is mathematically possible to build an actual time machine – what’s holding us back is finding materials that can physically

It seems like it’s getting harder and harder to get a good night’s sleep. Myriad distractions are in cahoots, keeping you from getting enough shut-eye. We’re supposed to get seven to nine hours of sleep, but many Americans don’t hit that target every night. Sleep can provide incredible health benefits, like helping us lose weight, improving our memories, and even

Mas Subramanian, a chemist and Oregon State University professor, became known in 2009 when his lab discovered the first new blue pigment, called YInMn Blue, in 200 years.  Now, Crayola is making the blue into a crayon.   As NPR notes, the scientific breakthrough was a happy accident. In 2009, a student in his lab combined yttrium, indium, and manganese oxides (a
