Scientists have reported that a previously unobserved process known as “mechanical annealing” explains why structures made of metal get stronger as their dimensions shrink to the micrometer scale or less.

Intelligence has more to do with when and how the brain grows rather than its overall size, suggests a new study.
In the brightest children, the thickness of the prefrontal cortex — a brain region thought to be responsible for many facets of intelligence — increased rapidly through their pre-teen years before thinning out again after the age of 11. The pattern was the same in those of average… read more

New calculations by Harvard theorist Avi Loeb show that the ideal time to study the cosmos was more than 13 billion years ago, just about 500 million years after the Big Bang — the era when the first stars and galaxies began to form.
The farther into the future you go from that time, the more information you lose about the early universe, he says.
However, modern… read more

A debate on transhumanism has been going on for the past few years, with naysayers and doomsayers on one side, optimistic futurists on the other, and too little in between.

MIT researchers, in collaboration with physicist Yves Couder at the Université Paris Diderot and his colleagues, report that they have produced the fluidic analogue of a classic quantum experiment, in which electrons are confined to a circular “corral” by a ring of ions.

There is a reason why “realistic” animation in films creeps us out. And creators are growing wary of the trap.

New research shows that babies display glimmers of consciousness and memory as early as 5 months old, Science Now reports.
Studies on adults show a particular pattern of brain activity: When your senses detect something, such as a moving object, the vision center of your brain activates, even if the object goes by too fast for you to notice. But if the object remains in your visual… read more

The year is 2032. You have just celebrated your 80th birthday and you have some tough decisions ahead. You can either keep repairing your current body or move into a new one.
The growing of “blank” bodies has become all the rage, and by using your own genetic material, body farmers can even recreate your own face at age 20.
In just 20 years, this is an… read more

Robert Elder, commander of the Air Force Cyberspace Command, said his newly formed command, which defends military data, communications and control networks, is learning how to disable an opponent’s computer networks and crash its databases.

Applied Digital Solutions has announced plans to develop a service that would allow consumers to pay for merchandise using microchips implanted under their skin. Micro-chipped customers would scan themselves using special readers.

DIYBio.org, an online hub for sharing ideas on DIYbio (do-it-yourself biology) has grown to more than 2,000 members since its inception.
One of the movement’s rallying points is Genspace, a nonprofit laboratory in Brooklyn that is open to members of the public, regardless of scientific background. Similar labs have sprouted in Boston and San Francisco.
Genspace has roughly a dozen members, and each pays $100 a… read more

Scientists at Max Planck Institute for Medical Research in Heidelberg have succeeded in optically detecting individual action potentials in the brains of living animals.
They introduced fluorescent indicator proteins into the brain cells of mice via viral gene vectors. The light indicates which neurons are communicating with each other.

A system that lets severely disabled people steer a wheelchair using only their thoughts is under development.
Using a skullcap with electrodes, it noninvasively monitors the electrical activity of the wearer’s brain. A neural network can be trained to recognize different mental states, currently: “turn left,” “turn right” and “move forward.”
