Carbon nanotubes used to develop clothing that can double as batteries
Posted by Shailesh Prasad in categories: engineering, military, nanotechnology
Move over, Iron Man.
What makes this possible are the unique properties of carbon nanotubes: a large surface area that is strong, conductive and heat-resistant.
UC’s College of Engineering and Applied Science has a five-year agreement with the Air Force Research Laboratory to conduct research that can enhance military technology applications.

Turbo inductor cogeneration with MSR nuclear can economically replace oil
Posted by Bill Kemp in categories: engineering, nuclear energy, space travel
Bucknell has led advanced engineering teams at Chrysler and General Motors for three production high performance engine families. Was Senior Propulsion Engineer for the Raptor full-flow staged combustion methalox rocket at Space Exploration Technologies then Senior Propulsion Scientist for Divergent3D developing vehicle technologies.
In 2017, he described how high temperature (820−1000 degree celsius) nuclear power plants can solve produce synthetic fuel to replace oil.

‘Blind’ Cheetah 3 robot can climb stairs littered with obstacles
Posted by Dan Kummer in categories: engineering, robotics/AI
The 90-pound mechanical beast — about the size of a full-grown Labrador — is intentionally designed to do all this without relying on cameras or any external environmental sensors. Instead, it nimbly “feels” its way through its surroundings in a way that engineers describe as “blind locomotion,” much like making one’s way across a pitch-black room.
“There are many unexpected behaviors the robot should be able to handle without relying too much on vision,” says the robot’s designer, Sangbae Kim, associate professor of mechanical engineering at MIT. “Vision can be noisy, slightly inaccurate, and sometimes not available, and if you rely too much on vision, your robot has to be very accurate in position and eventually will be slow. So we want the robot to rely more on tactile information. That way, it can handle unexpected obstacles while moving fast.”
Researchers will present the robot’s vision-free capabilities in October at the International Conference on Intelligent Robots, in Madrid. In addition to blind locomotion, the team will demonstrate the robot’s improved hardware, including an expanded range of motion compared to its predecessor Cheetah 2, that allows the robot to stretch backwards and forwards, and twist from side to side, much like a cat limbering up to pounce.

Drug gets body cells to ‘eat’ cancer
Posted by Genevieve Klien in categories: biotech/medical, engineering
Scientists have designed a special type of drug that helps the body eat and destroy cancerous cells.
The treatment boosts the action of white blood cells, called macrophages, that the immune system uses to gobble up unwanted invaders.
Tests in mice showed the therapy worked for aggressive breast and skin tumours, Nature Biomedical Engineering journal reports.

Electricity from germs could be the next big thing, say Israeli researchers
Posted by Klaus Baldauf in categories: biotech/medical, engineering, habitats, nanotechnology, nuclear energy, solar power, sustainability
You can generate electricity from oil, you can produce it from natural gas, you can make it from nuclear energy, and you can channel it from the sun, via solar energy conversion systems. You can even generate electricity from photosynthetic bacteria, also known as cyanobacteria, based on a new innovation developed at the Technion. As published in a study in the journal, Nature Communications, the Technion researchers have developed an energy-producing system that exploits both the photosynthesis and respiratory processes that cyanobacteria undergo, with the harvested energy leveraged to generate electricity based on hydrogen.
The study was conducted by three Technion faculty members: Professor Noam Adir from the Schulich Faculty of Chemistry, Professor Gadi Schuster from the Faculty of Biology, and Professor Avner Rothschild, from the Faculty of Materials Science and Engineering. The work involved collaboration between Dr. Gadiel Saper and Dr. Dan Kallmann, as well as colleagues from Bochum, Germany and the Weizmann Institute of Science. It was supported by various bodies, including the Nancy and Stephen Grand Technion Energy Program (GTEP), the Russell Berrie Nanotechnology Institute (RBNI), the Technion Hydrogen Technologies Research Lab (HTRL), the Adelis Foundation, the Planning and Budgeting Committee’s I-CORE program, the Israel Science Foundation, the USA-Israel Binational Science Fund (BSF) and the German research fund (DFG-DIP).
Scientists have long considered cyanobacteria a possible energy source. Cyanobacteria belong to a family of bacteria common to lakes, seas, and many other habitats. The bacteria use photosynthetic mechanisms that enable them to generate energy from sunlight. They also generate energy in the dark, via respiratory mechanisms based on digestion and degradation of sugar.

Groundbreaking technology successfully rewarms large-scale tissues preserved at very low temperatures
Posted by Nicholi Avery in categories: biotech/medical, engineering
MINNEAPOLIS/ST.PAUL (03/01/17) — A research team, led by the University of Minnesota, has discovered a groundbreaking process to successfully rewarm large-scale animal heart valves and blood vessels preserved at very low temperatures. The discovery is a major step forward in saving millions of human lives by increasing the availability of organs and tissues for transplantation through the establishment of tissue and organ banks.
The research was published today in Science Translational Medicine, a peer-reviewed research journal published by the American Association for the Advancement of Sciences (AAAS). The University of Minnesota holds two patents related to this discovery.
“This is the first time that anyone has been able to scale up to a larger biological system and demonstrate successful, fast, and uniform warming hundreds of degrees Celsius per minute of preserved tissue without damaging the tissue,” said University of Minnesota mechanical engineering and biomedical engineering professor John Bischof, the senior author of the study.
