Mercedes-Benz is trying to cut down on hearing damage caused by the deafening crunch of a car crash, and it’s doing so by blasting pink noise through the stereo when you’re about to hit something, to trigger a fascinating physical response.

Mercedes-Benz has done a lot to push automotive safety forward over its long history. In 1978, the S-class offered the first (or one of the first, depending on who you ask) 4-wheel ABS systems on a production car. In 1987, along with BMW and Toyota, Mercedes put the first traction control systems into production cars.

More recently, in 2003, the company introduced its Pre-Safe system, a series of measures that kick in when the vehicle detects what it decides is an inevitable crash. Seat belts quickly tension to an optimum point, windows and sunroofs close, the seats puff up to stabilize the bodies in them, and in some cases they even move slightly toward the center of the car before impact.

“If we were to draw energy from a typical AA battery based on this design, it would last for a billion years.” — Sungsik Lee, PhD, in the journal Science.

The transistors can be produced at low temperatures and can be printed on almost any material, such as glass, plastic, polyester fabrics, and paper.

Similar to a computer in sleep mode, the new transistor harnesses a tiny “leakage” of electrical current, known as “near-off-state current.” This leak at the point of contact between the metal and semiconducting components of a transistor, the “Schottky barrier,” is normally an undesirable characteristic of all transistors.

A team of astronomers believes that strange signals emanating from a cluster of stars are actually aliens trying to tell the universe they exist.

The study, which appeared in the Publications of the Astronomical Society of the Pacific, analyzed the odd beams of light from 234 stars — a fraction of the 2.5 million that were observed.

The bizarre beacons led the paper’s authors, Ermanno F. Borra and Eric Trottier from Laval University in Quebec, to conclude that it’s “probably” aliens.

A brown pebble discovered on an English beach more a decade ago is actually the world’s first known example of a fossilized dinosaur brain, scientists have confirmed.

The remarkable find is thought to have come from a large plant-eater such as the Iguanodon, which walked the earth about 133 million years ago.

It is believed the creature must have died near water with its head buried in sediment in a swamp or boggy ground, allowing its brain to be “pickled” and preserved.
