Awesome!
Scientists have harvested seven miniature human organs and combined them to create a ‘human-on-a-chip’.
The £26 million mini ‘man’ is being unveiled today at the organ-on-a-chip World Congress 2016 held in Boston, Massachussetts.
Previous innovations include growing a liver, a lung and part of the gut on a similar ‘chip’.
Nice.
Abstract: Researchers have developed a way to use less platinum in chemical reactions commonly used in the clean energy, green chemicals, and automotive industries, according to a paper in Science.
Led by the University of New Mexico in collaboration with Washington State University, the researchers developed a unique approach for trapping platinum atoms that improves the efficiency and stability of the reactions.
Platinum is used as a catalyst in many clean energy processes, including in catalytic converters and fuel cells. The precious metal facilitates chemical reactions for many commonly used products and processes, such as converting poisonous carbon monoxide to less harmful carbon dioxide in catalytic converters.
Aalto University scientists have broken the world record by fourteen fold in the energy resolution of thermal photodetection.
The record was made using a partially superconducting microwave detector. The discovery may lead to ultrasensitive cameras and accessories for the emerging quantum computer.

The first of the two key enabling developments is the new detector design consisting of tiny pieces of superconducting aluminum and a golden nanowire. This design guarantees both efficient absorption of incoming photons and very sensitive readout. The whole detector is smaller than a single human blood cell.
Glad Google is doing this because next month could be a real test when China launches its Quantum Satellite.
Today’s encryption is an arms race as digital security experts try to hold off hackers’ attempts to break open user data. But there’s a new tech on the horizon that even the NSA recognizes as crucial to protect against: quantum computing, which is expected to dramatically speed up attempts to crack some commonly-used cryptographic schemes. To get ahead of the game, Google is testing new digital security setups on single-digit populations of Chrome users.
Quantum computing is such a potential threat because it can do many more simultaneous calculations than current computers. Modern binary bits can only be in two states when electric current is run through them: 0 or 1. But the ambiguous nature of the quantum state means its elemental units (known as “qubits”) could be in either state at a time, so two could potentially be in four orientations at one time: 00, 01, 10 or 11. That ambiguity is exponential, so three qubits could be in eight at a time, and so on.
Security experts aren’t just concerned that quantum computers’ higher speed means faster rates of cryptography-cracking: They’re worried that future hacking methods could come back to today’s encrypted data and pry it open. But that’s in the future: as Wired points out, crypto experts say you would need a quantum computer with hundreds of thousands of qubits, and IBM’s only has five.
A special form of RNA called extra-coding RNA controls the careful targeting to add or remove methyl groups to chromosomal DNA of the adult neuron. The ecRNAs are fundamental regulators of DNA methylation patterns in the adult brain through interaction with DNA methyltransferase enzymes and are involved in creation of memories.
As we reported last month app collusion, where apps work together to extract sensitive data, now represents a very real security risk to mobile devices.
To address this emerging threat, component technology firm Formaltech, today is releasing FUSE, a DARPA-funded tool that detects inter-application collusion and other vulnerabilities in Android apps.
The FUSE platform identifies potential security vulnerabilities and tracks information flow through multiple apps, revealing potential collusion between apps. The tool uses static binary analysis to detect vulnerabilities without requiring the source code of the apps, allowing security professionals to analyze third party apps without the need for vendor cooperation. It operates in the cloud, supporting Android app (APK) analysis from anywhere. Developers and testers can easily drill down into the FUSE interface when FUSE displays errors, warnings and informational alarms.
