Just before a black hole and a neutron star collide, they may form a circuit that lights up for a few milliseconds – confirming Einstein’s theory.
As the challenges of particle physics have become more and more complex, we’ve had to plan and build larger and larger machines to explore the tiny subatomic world. But now, an international group of physicists has developed a technology to miniaturize particle accelerators, which could revolutionize physics and the life sciences.
The team has received a $13.5 million (£9 million) grant to develop a prototype particle accelerator that will fit in a shoebox. The technology being developed is called “accelerator-on-a-chip”. Electrons are made to travel through a channel within a silica chip. Shining a laser onto the chip produces an electric field, and the field is modified by the ridges within the channel. This set-up dramatically accelerates the electrons moving through the channel.
The prototype is based on independent experiments from the SLAC National Accelerator Laboratory in California and Friedrich-Alexander University Erlangen-Nuremberg (FAU) in Germany. Both teams discovered that these chips are capable of accelerating electrons to relativistic speed no matter the speed at which the electron was travelling before entering the channel. Also, the technology is capable of producing a larger acceleration gradient than current labs, which could reduce the size of particle accelerators – 100 meters (330 feet) of accelerator-on-a-chip would produce an acceleration equivalent to the 3.2-kilometer (two miles) SLAC linear accelerator, which is the longest in the world.
Researchers in Sweden have developed fully functional cyberplants, living plants which are engineered to host analog and digital electronic circuits, and the leaves can change colors. Using the vascular system of living roses, which distributes water and nutrients, the researchers were able to build key components of electronic circuits inside of the plants.
In February, NASA announced that it was investing in a $2 billion mission to Europa — a tiny moon of Jupiter that is one of the most likely places for life beyond Earth.
Their spacecraft, called the Europa Multi-Flyby Mission, would orbit Jupiter, taking frequent passes by Europa for a close look at its surface.
But there is another important piece of the puzzle that NASA is exploring, and in a recent conversation with US Rep. John Culberson (R-Texas), Ars Technica’s senior space editor, Eric Berger, reported the details — it’s a lander and it could be the key to discovering the first extraterrestrial life.
It was an audacious statement, but there it was.
Audi expects that 25 percent of the cars it sells just 10 years hence will be either battery-electric or plug-in hybrid models.
And it came directly from Scott Keogh, president of Audi of America, in front of a packed media audience at the Los Angeles Auto Show.

How thin can a camera be? Very, say Rice University researchers who have developed patented prototypes of their technological breakthrough.
FlatCam, invented by the Rice labs of electrical and computer engineers Richard Baraniuk and Ashok Veeraraghavan, is little more than a thin sensor chip with a mask that replaces lenses in a traditional camera.
Making it practical are the sophisticated computer algorithms that process what the sensor detects and converts the sensor measurements into images and videos.
