If a recent project using Google’s DeepMind were a recipe, you would take a pair of AI systems, images of animals, and a whole lot of computing power. Mix it all together, and you’ d get a series of imagined animals dream ed up by one of the AIs. A look through the research paper about the project—or this open Google Folder of images it produced—will likely lead you to agree that the results are a mix of impressive and downright eerie.

But t he eerie factor doesn’t mean the project shouldn’t be considered a success and a step forward for future uses of AI.

New research into a very weird type of ice known as Ice VII has revealed how it can form at speeds over 1,000 miles per hour (1,610 kilometres per hour), and how it might be able to spread across yet-to-be-explored alien worlds.

This ice type was only discovered occurring naturally in March, trapped inside diamonds deep underground, and this latest study looks in detail at how exactly it takes shape – apparently in a way that’s completely different to how water usually freezes into ice.

Based on a mathematical model devised by researchers from the Lawrence Livermore National Laboratory in California, there’s a certain pressure threshold across which Ice VII will spread with lightning speed. This process of near-instantaneous transformation is known as homogeneous nucleation.

Evidence has been building in recent years that our diet, our habits or traumatic experiences can have consequences for the health of our children — and even our grandchildren. The explanation that has gained most currency for how this occurs is so-called ‘epigenetic inheritance’ — patterns of chemical ‘marks’ on or around our DNA that are hypothesised to be passed down the generations. But new research from the University of Cambridge suggests that this mechanism of non-genetic inheritance is likely to be very rare.

A second study, also from Cambridge, suggests, however, that one way that environmental effects are passed on may in fact be through molecules produced from the DNA known as RNA that are found in a father’s sperm.

The mechanism by which we inherit innate characteristics from our parents is well understood: we inherit half of our genes from our mother and half from our father. However, the mechanism whereby a ‘memory’ of the parent’s environment and behaviour might be passed down through the generations is not understood.

Two teams demonstrate that they can count the number of quantized vibrations, or phonons, in cold mechanical oscillators by measuring the energy in the vibrations.

At the origin of every musical note is a mechanical oscillator that resonates at a specific frequency. But what the ear cannot distinguish is that the energy of these vibrations is discretized into an integer number of quanta of motion, or phonons. Most vibrating objects contain an uncountable number of phonons, but researchers have, for some time now, been able to prepare massive mechanical oscillators in their quantum ground state, where the average phonon number is smaller than one. This hard-won accomplishment not only involved getting rid of all thermal excitations in the oscillator through intense cooling, but it also required inventing a system of motion detection with a sensitivity at the quantum level [1]. An emerging technique consists of coupling the oscillator motion to another quantum object: a superconducting qubit, which can serve a role in the detection as well as the manipulation of states of motion [2–4].

The FDA has recently given 510(k) clearance to the OpenSight Augmented Reality System, the first augmented reality (AR) medical solution for Microsoft HoloLens cleared for use in pre-operative surgical planning.

The technology projects 2D, 3D and 4D images of patients interactively by overlaying them onto the patient’s body, according to a Novarad press release published Oct. 24.

OpenSight specifically utilizes the Microsoft HoloLens headset that allows simultaneous visualization of the 3D patient images in AR and the actual patient and their real-world surroundings. The technique may decrease operative times and improve surgical planning and the understanding of anatomic relationships.
