Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Northwestern University have discovered that common bacteria can turn microgears when suspended in a solution, providing insights for designs of bio-inspired dynamically adaptive materials for energy.
“The ability to harness and control the power of bacterial motion is an important requirement for further development of hybrid biomechanical systems driven by microorganisms,” said Argonne physicist and principal investigator Igor Aronson. “In this system, the gears are a million times more massive than the bacteria.”
Militants in Iraq have used $26 off-the-shelf software to intercept live video feeds from U.S. Predator drones, potentially providing them with information they need to evade or monitor U.S. military operations.
Senior defense and intelligence officials said Iranian-backed insurgents intercepted the video feeds by taking advantage of an unprotected communications link in some of the remotely flown planes’ systems. Shiite fighters in Iraq used software programs such as SkyGrabber — available for as little as $25.95 on the Internet — to regularly capture drone video feeds, according to a person familiar with reports on the matter.
Science Fiction (SF) literature, artwork and films are works of imagination, but often contain some elements of plausibility, with the story revolving around some known facts as well as inventions and possibilities that are to all intents and purposes beyond our current technologies. Although Science Fiction is not about predicting the future, several SF authors have taken modern technology and concepts (of their own time) and anticipated with some accuracy how new technologies would change our lives, well before these technologies were actually possible.
Cyber war has moved from fiction to fact, says a report. Compiled by security firm McAfee, it bases its conclusion on analysis of recent net-based attacks. Analysis of the motives of the actors behind many attacks carried out via the internet showed that many were mounted with a explicitly political aim. It said that many nations were now arming to defend themselves in a cyber war and readying forces to conduct their own attacks.
While definitions of what constitutes cyber war are not shared, it was clear that many nations were preparing for a future in which conflict was partly conducted via the net. ”There are at least five countries known to be arming themselves for this kind of conflict,” said Greg Day, primary analyst for security at McAfee Europe.
The UK, Germany, France, China and North Korea are known to be developing their own capabilities.
Nasa’s experiment last month to find water on the Moon was a major success, US scientists have announced.
The space agency smashed a rocket and probe into a large crater at the lunar south pole, hoping to kick up ice.
Scientists who have studied the data now say instruments trained on the impact plume saw copious quantities of water vapour.
One researcher described this as the equivalent of “a dozen two-gallon buckets” of water.
The 1.6km-high plume of debris was kicked up by the Lunar Crater Observation and Sensing Satellite (LCROSS) last month when it crashed into Cabeus crater.
“We’re unlocking the mysteries of our nearest neighbour and, by extension, the Solar System,” said Michael Wargo, chief lunar scientist at Nasa’s headquarters in Washington DC.
“The Moon harbours many secrets, and LCROSS has added a new layer to our understanding.”
The identification of water-ice in the impact plume is important for purely scientific reasons, but also because a supply of water on the Moon would be a vital resource for future human exploration.
Finally some useful research from NASA, BBC reports. Now let’s get that space-elevator hooked up to a permanent base.
From the US Army War College’s Center for Strategic Leadership and The SecDev Group comes “Bullets and Blogs: New Media and the Warfighter” (2.7mb PDF). The report is based on a three-day workshop that took place at Carlisle Barracks in January 2008, one of the best events I have attended. It is required reading for anyone (e.g. more then than the Defense community) involved in the modern information environment.
Imagine purchasing a new Rovio robot. This wheeled mobile robot sports a webcam and can be accessed easily through the internet. Often these and other robots are bought as toys, used by the owners to check on their home during a vacation, perhaps for teleconferencing, or to check on an elderly loved one.
Now imagine a malevolent hacker from Russia or China, or your next door neighbor, or a even stalker gaining access to this robot. Now they have free access to your home, roving about checking to see if the owner is home, spying on your children, or perhaps taking embarrassing video of you or your family. What if the robot is commanded to break items in your home, hide your keys, or drive under the feet of granny to harm her? Millions of these robots have been sold, meaning they are quite ubiquitous and therefore prime targets of malicious hackers.
A document recently leaked by the website Wikileaks has revealed the concerns of British intelligence agencies about the focus of Chinese spies increasing in scope from stealing technology and reverse-engineering it to include the understanding of production techniques and methodologies in order to reproduce them cheaply and also warns of the military implications of such an increased focus.
The 2,389 page document, in its estimate of Chinese intelligence aims, says, “Chinese intelligence activity is widespread and has a voracious appetite for all kinds of information; political, military,commercial, scientific and technical. It is on this area that the Chinese place their highest priority and where we assess that the greatest risk lies.”
The document elaborates, “The Chinese have realized that it is not productive to simply steal technology and then try to `reverse engineer it’. Through intelligence activity they now attempt to acquire an in-depth understanding of production techniques and methodologies. There is an obvious economic risk to the UK. Our hard earned processes at very little cost and then reproduce them with cheap labor. ”
