ETH researchers have integrated two CRISPR-Cas9-based core processors into human cells. This represents a huge step towards creating powerful biocomputers.

Controlling gene expression through gene switches based on a model borrowed from the digital world has long been one of the primary objectives of synthetic biology. The digital technique uses what are known as logic gates to process input signals, creating circuits where, for example, output signal C is produced only when input signals A and B are simultaneously present.

To date, biotechnologists had attempted to build such digital circuits with the help of protein gene switches in cells. However, these had some serious disadvantages: they were not very flexible, could accept only simple programming, and were capable of processing just one input at a time, such as a specific metabolic molecule. More complex computational processes in cells are thus possible only under certain conditions, are unreliable, and frequently fail.

At an event in Beijing, Intel debuted the Neural Compute Stick 2, which packs a Myriad X system-on-chip it claims has an 8 times performance advantage.

Next-generation, low-power optical data transmission may rely on polarization rather than switching laser pulses on and off.

Researchers hoping to better interpret data from the detection of gravitational waves generated by the collision of binary black holes are turning to the public for help.

West Virginia University assistant professor Zachariah Etienne is leading what will soon become a global volunteer computing effort. The public will be invited to lend their own computers to help the scientific community unlock the secrets contained in gravitational waves observed when black holes smash together.

LIGO’s first detection of gravitational waves from colliding black holes in 2015 opened a new window on the universe, enabling scientists to observe cosmic events spanning billions of years and to better understand the makeup of the Universe. For many scientists, the discovery also fueled expansion of efforts to more thoroughly test the theories that help explain how the universe works—with a particular focus on inferring as much information as possible about the black holes prior to their collision.

The U.S. Army’s next assault rifle and machine gun will have built-in computers to give soldiers unparalleled firing accuracy. The so-called Next Generation Squad Weapons will feature a digital fire control system borrowing many features from today’s main battle tanks, allowing shooters to engage targets faster and with greater precision than their opponents can muster.

Next generation infantry weapons will incorporate computer technology previously only available on tanks.

Ultra-secure online communications, completely indecipherable if intercepted, is one step closer with the help of a recently published discovery by University of Oregon physicist Ben Alemán.

Alemán, a member of the UO’s Center for Optical, Molecular, and Quantum Science, has made artificial atoms that work in ambient conditions. The research, published in the journal Nano Letters, could be a big step in efforts to develop secure quantum communication networks and all-optical quantum computing.

“The big breakthrough is that we’ve discovered a simple, scalable way to nanofabricate artificial atoms onto a microchip, and that the artificial atoms work in air and at room temperature,” said Alemán, also a member of the UO’s Materials Science Institute.
