Human babies and mouse pups both automatically and deeply relax when carried by their mums, new research has revealed. The study showed the babies' heart rates slowed down and their nervous and motor systems relaxed when they were carried, suggesting it doesn't just feel good, its an essential mother-infant interaction.

Overhunting is one reason for wildlife population decline, but do these animals even know what we’re doing to them? New research suggests that they do. Woolly monkeys in the Amazon were observed to react differently to people in their territory, depending on the behavior of the human.

In areas where hunting is heavy, humans gathering food or performing research do not elicit much of a response from the monkeys. Hunters, however, result in the monkeys becoming very quiet and motionless. In quieter areas where human contact is less frequent, the monkeys are more wary of the researchers and gatherers. This indicates that the monkeys are behaving based on experience.

The long term advantage of this behavior is uncertain. Woolly monkeys are highl ...

Developed in the University of California, Berkeley, lab of Daniel Fletcher, the CellScope, here trained on an algae sample, turns the camera of a standard cell phone into a diagnostic-quality microscope with a magnification of 5x–60x.

A new study out of Harvard University shows that pasteurized milk products from factory farms is linked to causing hormone-dependent cancers. It turns out that the concentrated animal feeding operations model of raising cows on factory farms churns out milk with dangerously high levels of estrone sulfate, an estrogen compound linked to testicular, prostate, and breast cancers.

Dr. Ganmaa Davaasambuu, Ph.D., and her colleagues specifically identified "milk from modern dairy farms" as the culprit, referring to large-scale confinement operations where cows are milked 300 days of the year, including while they are pregnant. Compared to raw milk from her native Mongolia, which is extracted only during the first six months after cows have already ...

Swedish engineers have developed a system that turns sweat into potable water. The Sweat Machine spins clothes to extract liquid from the fibres, filters it and transforms it into water. Their developers say the water extracted from the machine is cleaner than ordinary tap water.

Engineers are building special drones that will deliver food to your table – or home. Besides the iTray, which brings customers sushi at a Japanese restaurant in London (above), researchers have developed a 'tacocopter' and 'pizzacopter' that can traverse six kilometers in ten minutes. But don’t get your hopes up yet, there are plenty of technological barriers to overcome before drones deliver pizzas to our homes.

The hyperloop would be solar powered and connect cities up to 900 miles away from each other. The passenger pods would be enclosed, which diminishes concerns about weather and interacting with wildlife. The designer of the hyperloop is Elon Musk, the founder of SpaceX and Tesla Motors.

There are still issues to work out before the plan would be practical, but it is an exciting look forward to alternative modes of transportation.
