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.

I hate that I am going to miss the Farnborough airshow.
The Farnborough airshow begins next week and will feature a number of announcements from the 3D printing industry. The show only takes place once every 2 years and will see a flurry of news and displays of the latest aviation technology. These include Boeing’s 737 MAX airliner with its 3D printed LEAP engines and also demonstrations by the first Lockheed Martin F-35 Lighting II, or Joint Strike Fighter, stealth jets to arrive in the UK.
Additive manufacturing company Norsk Titanium (NTi) hopes their announcements will make an equally large splash. During 2016 a number of press releases by the company have piqued the interest of insiders in the 3D printing industry and also in the aerospace industry. Outside of this group, the name Norsk Titanium may be relatively unknown.
Nice.
“Our study suggests for the first time that the doping-induced modulation of the charge carrier density in graphene influences its wettability and adhesion,” explained SungWoo Nam, an assistant professor in the Department of Mechanical Science and Engineering at Illinois. “This work investigates this new doping-induced tunable wetting phenomena which is unique to graphene and potentially other 2D materials in complementary theoretical and experimental investigations.”
Graphene, being optically transparent and possessing superior electrical and mechanical properties, can revolutionize the fields of surface coatings and electrowetting displays, according to the researchers. A material’s wettability (i.e. interaction with water) is typically constant in the absence of external influence and are classified as either water-loving (hydrophilic) or water-repelling (hydrophobic; water beads up on the surface). Depending on the specific application, a choice between either hydrophobic or hydrophilic material is required. For electrowetting displays, for example, the hydrophilic characteristics of display material is enhanced with the help of a constant externally impressed electric current.
“What makes graphene special is that, unlike conventional bulk materials, it displays tunable surface wetting characteristics due to a change in its electron density, or by doping,” said Ali Ashraf, a graduate student researcher and first author of the paper, “Doping-Induced Tunable Wettability and Adhesion of Graphene,” appearing in Nano Letters. “Our collaborative research teams have discovered that while graphene behaves typically as a hydrophobic material (due to presence of strongly held air-borne contamination on its surface), its hydrophobicity can be readily changed by changing electron density.
Biocomputing/ living circuit computing/ gene circuitry are the longer term future beyond Quantum. Here is another one of the many building blocks.
The tiny molecule responsible for transmitting the genetic data for every living thing on earth could be the answer to the IT industry’s quest for a more compact storage medium. In fact, researchers from Microsoft and the University of Washington recently succeeded in storing 200 MB of data on a few strands of DNA, occupying a small dot on a test tube many times smaller than the tip of a pencil.
The Internet in a Shoebox.
Despite the small space occupied by the DNA strands, the researchers were nonetheless able to successfully store and retrieve high-definition digital video, the top 100 books from Project Guttenberg, and copies of the Universal Declaration of Human Rights in more than 100 languages.
