The Nobel Prize in Chemistry 2016 was awarded today to Jean-Pierre Sauvage, PhD, Sir J. Fraser Stoddart,PhD, and Bernard L. Feringa, PhD, for their design and production of molecular machines. They have developed molecules with controllable movements, which can perform a task when energy is added.

The first step towards a molecular machine was taken by Jean-Pierre Sauvage in 1983, when he succeeded in linking two ring-shaped molecules together… read more

A new safer catheter design that allows cardiologists to see inside arteries for the first time and remove plaque from only diseased tissue has been used by interventional cardiologists at UC San Diego Health.

The new image-guided device, Avinger’s Pantheris, allows doctors to see and remove plaque simultaneously during an atherectomy — a minimally invasive procedure that involves cutting plaque away from the artery and… read more

Engineers at the University of Washington have created genetically engineered peptides that self-assemble into arrays of nanowires on two-dimensional nanosheets (single-layer graphene and molybdenum disulfide) to relay information across a bio-nano interface — a first step towards fully self-assembled future biomedical and electro-optical bionanoelectronic devices.

Arrays of peptides could provide organized scaffolds for functional biomolecules, enabling nanoscale bioelectronics interfaces. And designed peptides could be incorporated with metal… read more

A bio-inspired electronic device called a memristor could allow for real-time processing of neuronal signals (spiking events), new research led by the University of Southampton has demonstrated.

The research could lead to using multi-electrode array implants for detecting spikes in the brain’s electrical signals from more than 1,000 recording channels to help treat neurological conditions, without requiring expensive, high-bandwidth, bulky systems for processing data. The research… read more

University of Washington computer scientists and electrical engineers have devised a way to send secure passwords through the human body, using benign, low-frequency transmissions already generated by fingerprint sensors and touchpads on consumer devices.

“Let’s say I want to open a door using an electronic smart lock,” said Merhdad Hessar, a UW electrical engineering doctoral student and co-lead author of a paper presented in September at the … read more

Graphene crowd-surfs on a lipid monolayer

Could provide a versatile new platform for biosensors and drug delivery systems

“Crowd-surfing” on a smooth, supportive lipid monolayer, graphene could provide a versatile new platform for biosensors and drug delivery systems, researchers at Leiden University in The Netherlands have discovered.

Graphene is typically supported or sandwiched with other two-dimensional materials to promote higher mobility, ensure consistent electrical performance, and prevent environmental contamination. But combining graphene with soft, dynamic, molecular self-assembled lipid monolayers could provide a versatile platform for applications such… read more

IBM announces AI-powered decision-making

D-Wave Systems announced Tuesday (Sept. 28, 2016) a new 2000-qubit processor, doubling the number of qubits over the previous-generation D-Wave 2X system. The new system will enable larger problems to be solved and performance improvements of up to 1000 times.

D-Wave’s quantum system runs a quantum-annealing algorithm to find the lowest points in a virtual energy landscape representing a computational problem to be solved. The lowest points… read more

Scientists at ETH Rehabilitation Engineering Laboratory in Switzerland have invented a robotic system that they say could fundamentally change the daily lives of stroke patients.

According to the ETH scientists, one in six people will suffer a stroke in their lifetime; two thirds of those affected suffer from paralysis of the arm. Intensive clinical training, including robot-assisted therapy, can help patients regain a degree of limited control over their… read more

Smoking leaves its “footprint” on the human genome in the form of DNA methylation, a process that affects what genes are turned on, according to new research in Circulation: Cardiovascular Genetics, an American Heart Association journal.

The new findings could provide researchers with potential targets for new therapies.

“These results are important because methylation, as one of the mechanisms of the regulation of gene expression, affects… read more

How to watch the US presidential debates in VR

MITCSAIL | EQ-Radio: Emotion Recognition using Wireless Signals

MIT researchers from have developed “EQ-Radio,” a device that can detect a person’s emotions using wireless signals.

By measuring subtle changes in breathing and heart rhythms, EQ-Radio is 87 percent accurate at detecting if a person is excited, happy, angry or sad — and can do so without on-body sensors, according to the researchers.

“Over the past year or two, someone has been probing the defenses of the companies that run critical pieces of the Internet,” according to a blog post by security expert Bruce Schneier.

“These probes take the form of precisely calibrated attacks designed to determine exactly how well these companies can defend themselves, and what would be required to take them down. It feels like a nation’s military… read more

Self-powered ‘materials that compute’ and recognize simple patterns

September 20, 2016

Synchronized pattern recognition

University of Pittsburgh researchers have modeled the design of a “material that computes” — a hybrid material, powered only by its own chemical reactions, that can recognize simple patterns.

The material could one day be integrated into clothing and used to monitor the human body, or developed as a skin for “squishy” robots, for example, according to the researchers, writing in the open-access AAAS journal Science Advances.
