This computational illustration shows a graphene network structure below a layer of water.
New analysis finds way to safely conduct heat from graphene to biological tissues.
Ouch!!!
National Security Agency says tools left exposed by mistake — and dumping by presumably Russia-backed hackers Shadow Brokers.
An FBI investigation into the public dumping of hacking tools used by the National Security Agency (NSA) to uncover security flaws in some networking vendor products is looking at how the tools were exposed on a remote computer, a Reuters report says, quoting people close to the investigation.

When the computer is addressed in many science fiction shows, it often replies in a female-coded voice. From Majel Roddenberry’s Federation computer voice in the Star Trek series to the sentient ship AIs in Andromeda, Killjoys, Dark Matter, Outlaw Star, and Mass Effect, artificial intelligence has been a science fiction regular since at least the 1960’s. There are male-coded AIs as well—J.A.R.V.I.S., Hal, that weird Haley Joel Osment-bot from A.I.—but women have been part of humanity’s relationship with electric computers since the very beginning.
Jennifer S. Light’s article “When Computers Were Women” discusses the ENIAC (Electronic Numerical Integrator and Computer) project during World War II, and how the people doing the actual computational tasks were a group of civilian and military women. The women were actually the “computers,” and were creating a machine that would someday replace them. The concept of the women as the actual computers made me think about how many artificial intelligences, whether in android form or integrated into actual ships, are coded female.
Light’s article also pointed out that history buried these early female computers. Their work was made light of, devalued, and all credit was given to the male inventors of ENIAC, reducing them practically to “ghost in the machine” status. This is where my mind made the connection. So many computer and AI characters are coded female because even layers of sexism and inequality still can’t erase the connection between the first “computers” being women and the task of computing. You can take the woman out of the workplace, but you can’t take the woman out of the machine she helped create.
Tiny sensors made through nanoscale 3D printing may be the basis for the next generation of atomic force microscopes. These nanosensors can enhance the microscopes’ sensitivity and detection speed by miniaturizing their detection component up to 100 times. The sensors were used in a real-world application for the first time at EPFL, and the results are published in Nature Communications.

Researchers from the Graphene Flagship use layered materials to create an all-electrical quantum light emitting diodes (LED) with single-photon emission. These LEDs have potential as on-chip photon sources in quantum information applications.
Atomically thin LEDs emitting one photon at a time have been developed by researchers from the Graphene Flagship. Constructed of layers of atomically thin materials, including transition metal dichalcogenides (TMDs), graphene, and boron nitride, the ultra-thin LEDs showing all-electrical single photon generation could be excellent on-chip quantum light sources for a wide range of photonics applications for quantum communications and networks. The research, reported in Nature Communications, was led by the University of Cambridge, UK.
The ultra-thin devices reported in the paper are constructed of thin layers of different layered materials, stacked together to form a heterostructure. Electrical current is injected into the device, tunnelling from single-layer graphene, through few-layer boron nitride acting as a tunnel barrier, and into the mono- or bi-layer TMD material, such as tungsten diselenide (WSe2), where electrons recombine with holes to emit single photons. At high currents, this recombination occurs across the whole surface of the device, while at low currents, the quantum behaviour is apparent and the recombination is concentrated in highly localised quantum emitters.
Google said that one of its self-driving cars was involved in an accident in Mountain View, California last week. The accident was first reported Friday by 9to5 Google, which characterized the incident as Google’s “worst accident yet.”
In a statement, Google insisted its driverless car was not at fault. A crash report with the DMV has yet to be posted, so all the details have yet to be confirmed.
According to the Google, the accident occurred when a vehicle heading west on El Camino Real in Mountain View ran a red light and collided with the right side of a Google self-driving vehicle that was traveling northbound on Phyllis Ave. “Our light was green for at least six seconds before our car entered the intersection,” a spokesperson said.

Jupiter’s moon Europa — a giant ice ball thought to hide twice as much liquid water as there is on Earth — just became an even hotter target in the search for aliens.
Scientists on Monday unveiled new photographs from NASA’s Hubble Space Telescope, and they likely show ‘fingers’ of water vapour squirting out of Europa’s hidden ocean and into space.
The grainy Hubble photos, taken in 2014, suggest water plumes occasionally shoot 125 miles (200 km) into space, then rain back down on the surface. If true, this would be Hubble’s second time catching Europa’s water plumes since 2012.
