University of Washington researchers have proved that it's possible to use one's thoughts to remotely control another person's body movements.

Thermoelectric materials can see their performance radically improved via the utilization of an array of 'nanoscale pillars,' according to new research from the University of Colorado Boulder. These tiny pillars, built directly onto the thermoelectric material, will reduce the heat flow through the material by a factor of two while not affecting the electrical flow.

RMIT University researchers in Melbourne, Australia, have developed the world's first liquid metal enabled pump, a revolutionary new micro-scale device with no mechanical parts. The unique design will enable micro-fluidics and lab-on-a-chip technology to finally realise their potential, with applications ranging from biomedicine to biofuels.

Interesting discussion is going about, on how work anxiety is spreading in academia, with possible mental consequences. And with robust links to the "Doing What You Love" motto of life/work. Could be proven an unsustainable model though. Recalling of Higgs' recent declaration, that today's Academia productivity demands would be hectic for him, could point to the direction of the problem and the solution...?

"Cuckoos have a bad reputation as home-wreckers, taking over the nests of other birds and killing their chicks. But one species benefits its hosts by producing a smelly fluid that repels predators. "Cuckoos are not always the villains we think they are," says Ros Gloag of the University of Sydney, who was not involved in the study."

So they not only take over part of the nest, but also crap all over the place? Then again, if that is the prize to pay for safety, it might well be worth the inconvenience.. :)

Here you go. You can now scrap Lisa altogether. Who's going to tell Pacome?

Awesome and exciting stuff indeed! The data pinpoint the time when inflation occurred - about 10E-37 seconds into the Universe's life - and its temperature at the time, corresponding to energies of about 10E16 gigaelectronvolts, says cosmologist Michael Turner of the University of Chicago. That is the same energy at which three of the four fundamental forces of nature - the weak, strong and electromagnetic force - are expected to become indistinguishable from one another in a model known as the grand unified theory. I expect more fundamental physics insights to come out of this in the future. A full-sky survey from space may still be an interesting addition to the measurement capabilities, so I would not rule out LISA all together I guess...

Siemens is using neural networks to improve operation of wind turbines, reducing maintenaince needs and improving output by one precent. It seems even that Siemens has quite a large neural network study group, probably linked to german universities, with various examples in practice (see websie)

Artificial and natural knowledge researchers at the University of Illinois at Chicago have IQ-tested one of the best available artificial intelligence systems to see how intelligent it really is. Turns out it's about as smart as the average 4-year-old, they will report July 17 at the U.S. Artificial Intelligence Conference in Bellevue, Wash.

Something for our Nano structure fans. Funniest remark: "One of the researchers got to take advantage of his Russian language skills since some of the chemistry details necessary for understanding the reaction mechanism was only available in an old Russian PhD thesis."

Quote: "This is exactly what we are pursuing - self-assembling materials that organize at smaller sizes, say, less than 20 or even 10 nanometers"

Direct Self-Assembly (DSA) is one of the competitors for the next-generation 'lithography' together with direct-write via electron beam and the more traditional extreme UV (EUV) lithography. Although there are huge benefits to use DSA, the technology does have some drawbacks when it comes to line edge roughness. It seems however particularly good for repetitive structures that are used in memory chips. As long as EUV is struggling to get it working, DSA definitely has a fighting chance to enter the market one day.

Black-body radiation can give rise to a net attractive force between tiny objects. That is the claim made by physicists at the University of Innsbruck in Austria, who have calculated the strength of this new force between a speck of dust and a hydrogen atom. Under some cirmustances this force could be stronger than gravitation. Read the paper here: http://prl.aps.org/abstract/PRL/v111/i2/e023601

In a jaw-dropping feat of engineering, electronics turn a person's thoughts into commands for a drone. Using a brain-computer interface technology pioneered by University of Minnesota biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring.

Pretty cool, so when is this going to be available for our quadrocopter?

We discussed this today during coffee. The inventor claims that he claims that a pressure differential can push hydrogen through a proton conductive membrane (thereby stripping off the electrons) which flow through an electric circuit and provide electric power. The type of membrane is fairly similar to that found in a hydrogen fuel cell. If the pressure differential is cause by selective heating this is in essence a heat engine that directly produces electricity. The inventor claims that this could be a high efficiency alternative to thermoelectric devices and could even outperform PV and Sterling engines with an efficiency close to that of fuel cells (e.g., ~60% @ dT=600K). I could not find any scientific publications as the inventor is not affiliated to any University - he has however an impressive number of patents from a very wide field (e.g., the "Super Soaker" squirt gun) and has worked on several NASA and US military projects. His current research seams to be funded by the latter as well. Here are some more links that I found: http://www.theatlantic.com/magazine/archive/2010/11/shooting-for-the-sun/308268/ http://www.johnsonems.com/?q=node/13 http://scholar.google.nl/scholar?q=%22lonnie+g+johnson%22+&btnG=&hl=nl&as_sdt=0%2C5

The most tiny autopilot in the world was introduced yesterday by the Technical University of Delft, The Netherlands. Named Lisa/s, she comes in at the scales with just a mere 1.9 grams, the 2*2 cm board has everything that a multirotor needs. Among the sensors are a 3 axle gyroscope, compass, barometer and a gps module.

Also hardware and software are open source!

An international team of researchers, led by physicists from Lund University, have confirmed the existence of what is considered a new element with atomic number 115. The experiment was conducted at the GSI research facility in Germany. The results confirm earlier measurements performed by research groups in Russia.

The telepathic cyborg lives, sort of. University of Washington scientists Rajesh Rao and Andrea Stocco claim that they are the first to demonstrate human brain-to-brain communication. Rao sent a signal into a Stocco's brain via the Internet that caused him to move his right hand.

Team leader Professor Steven Tingay, Director of the MWA at Curtin University and Chief Investigator in the Australian Research Council Centre for All-sky Astrophysics (CAASTRO) said the MWA will be able to detect the space junk by listening in to the radio signals generated by stations including popular youth network Triple J.

University at Buffalo researchers are developing a deep-sea Internet. The technological breakthrough could lead to improvements in tsunami detection, offshore oil and natural gas exploration, surveillance, pollution monitoring...

Damn... At Leiden University I worked on transmission of light through Ag nano-layers. This could have been an easy experiment. I wonder about the evanescence of the wave as visible light is usually attenuated to <5% within 250nm of silver.
