Stability of new-generation semiconductor lasers

New Semiconductor lasers — excellent news for Internet and medical technology.

Global stability analysis shows that new-generation semiconductor lasers may be dynamically more stable than conventional lasers despite having more degrees of freedom.

Semiconductor lasers are ubiquitous in everyday applications ranging from the Internet to medicine. Practically every laser application is affected by laser speed and stability properties. Stable operation is important for spectroscopy and optical clocks, while high-speed response is essential for optical communication schemes. When coupled to the outside world, or to one another (as in photonic integrated circuits), conventional semiconductor lasers often undergo instabilities that give rise to irregular and unpredictable oscillations in the intensity of the emitted light.1–3 These chaotic oscillations occur on a timescale of tens to hundreds of picoseconds and underpin modern laser applications, including instability-based sensing,4, 5 chaos-based secure optical communication,6 as well as ultrafast information processing,7 and random-number generation.

Scientists create a ‘HUMAN-on-a-chip‘

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’.

Fantastic voyage to the nanoverse one step closer

Robots so small they can enter the bloodstream and perform surgeries are one step closer, a research team from Monash University has discovered.

Led by Dr Zhe Liu, the Monash Engineering team has focused on graphene oxide — which is a single atom thick — as an effective shape memory material.

Graphene has captured world scientific and industrial interest for its miracle properties, with potential applications across energy, medicine, and even biomedical nano-robots.

Leading cancer centers in China to be equipped with C-RAD technology

Nice.

July 1, 2016 – C-RAD has received an order from its Chinese distributor for Catalyst™ and Sentinel™ systems, to be installed at leading cancer centers in China. The order has a total value of approximately 7.6 MSEK.

The Catalyst™ systems will be installed on Varian True Beam™ and Elekta Versa HD™ linear accelerators. The systems are delivered in different software configurations containing software modules for Patient Setup and Positioning and Respiratory Gating, including respective interfaces for communication with the treatment system. The interfaces allow a seamless integration for patient synchronization and an automated patient setup and beam control to treat tumors that may be moving due to respiratory motion.

GM working on ‘robo-glove’ for factories

General Motors is working with NASA and medical technologies company Bioservo to develop a battery-assisted robotic glove that can be used in assembly plants.

The technology was initially developed from a partnership between GM and NASA that resulted in RoboGlove, a force-multiplying tool that looks like a large electrified work glove.

The RoboGlove uses sensors and actuators comparable to the nerves, muscles and tendons in a human hand.

FDA approves first dissolving stent for US patients

Glad it has been approved. This would have been great for BMI technology as well; however, FDA limits it to only treat clogged arteries.

WASHINGTON (AP) — A medical implant that slowly dissolves into the body could be the answer to long-standing safety concerns with devices used to treat clogged arteries.

But not so fast, say experts.

Abbott Laboratories’ newly-approved Absorb stent comes with one important caveat: it hasn’t yet been shown to be safer than older metal implants.

Engineers Design Programmable RNA Vaccines That Protext Against Ebola and H1N1 Influenza

A newly published study details how engineers developed programmable RNA vaccines that work against Ebola, H1N1 influenza, and a common parasites in mice.

MIT engineers have developed a new type of easily customizable vaccine that can be manufactured in one week, allowing it to be rapidly deployed in response to disease outbreaks. So far, they have designed vaccines against Ebola, H1N1 influenza, and Toxoplasma gondii (a relative of the parasite that causes malaria), which were 100 percent effective in tests in mice.

The vaccine consists of strands of genetic material known as messenger RNA, which can be designed to code for any viral, bacterial, or parasitic protein. These molecules are then packaged into a molecule that delivers the RNA into cells, where it is translated into proteins that provoke an immune response from the host.
