Juggling By the Numbers

December 21st, 2012 12:08 admin View Comments


theodp writes “The BBC News’ Laura Gray reports on a juggling notation system developed in the 80′s called Siteswap (aka Quantum Juggling and Cambridge Notation) and how it has helped jugglers discover and share thousands of new tricks. Frustrated that there was no way to write down juggling moves, mathematician Colin Wright and others helped devised Siteswap, which uses sequences of numbers to encode the number of beats of each throw, which is related to their height and the hand to which the throw is made. ‘Siteswap has allowed jugglers to share tricks with each other without having to meet in person or film themselves,’ says James Grime, juggling enthusiast and math instructor for Cambridge University. Still unclear on the concept? Spend some time playing around with Paul Klimek’s most-excellent Quantum Juggling simulator, and you too can be a Flying Karamazov Brother!”

Cambridge University To Open “Terminator Center” To Study Threat From AI

November 25th, 2012 11:01 admin View Comments


If the thought of a robot apocalypse is keeping you up at night, you can relax. Scientists at Cambridge University are studying the potential problem. From the article: “A center for ‘terminator studies,’ where leading academics will study the threat that robots pose to humanity, is set to open at Cambridge University. Its purpose will be to study the four greatest threats to the human species – artificial intelligence, climate change, nuclear war and rogue biotechnology.”

ACM Queue Interviews Robert Watson On Open Source Hardware and Research

Operating Systems

An anonymous reader writes “ACM Queue interviews Cambridge researcher (and FreeBSD developer) Robert Watson on why processor designs need to change in order to better support security features like Capsicum — and how they change all the time (RISC, GPUs, etc). He also talks about the challenge of building a research team at Cambridge that could actually work with all levels of the stack: CPU design, operating systems, compilers, applications, and formal methods. The DARPA-sponsored SRI and Cambridge CTSRD project is building a new open source processor that can support orders of magnitude greater sandboxing than current designs.”

Ig Nobels Feature Exploding Colonoscopies, Left Leaning Views of Eiffel Tower

It's funny. Laugh.

alphadogg writes “The Ig Nobel Prize ceremony has honored a wide array of strange research and advancement over the years, from exploding pants to woodpecker headaches to aggressive parking enforcement, and Thursday night’s ceremony in Cambridge, Mass., was no exception. Particular highlights included a Russian company that turns ammunition into trace amounts of diamond, Japanese engineers who developed a speech jamming device, and research into such critical topics as why coffee is so hard to carry without slopping and what makes a ponytail move the way it does.”

Chip and Pin “Weakness” Exposed By Cambridge Researchers

September 12th, 2012 09:55 admin View Comments


another random user writes “A vulnerability in the widely used chip and pin payment system has been exposed by Cambridge University researchers. Cards were found to be open to a form of cloning, despite past assurances from banks that chip and pin could not be compromised. In a statement given to the BBC, a spokeswoman for the UK’s Financial Fraud Action group said: ‘We’ve never claimed that chip and pin is 100% secure and the industry has successfully adopted a multi-layered approach to detecting any newly-identified types of fraud.’”

University of Cambridge Offers Free Online Raspberry Pi Course

September 3rd, 2012 09:46 admin View Comments


Barence writes “The University of Cambridge has released a free 12-step online course on building a basic operating system for the Raspberry Pi. The course, Baking Pi — Operating Systems Development, was compiled by student Alex Chadwick during a summer interning in the school’s computer lab, and has been put online to help this year’s new recruits start work with the device. The university has already purchased a Raspberry Pi for every new Computer Science student starting in 2012.”

Calorie Restriction May Not Extend Lifespan

August 30th, 2012 08:29 admin View Comments


sciencehabit writes “Slash your food intake and you can live dramatically longer — at least if you’re a mouse or a nematode. But a major study designed to determine whether this regimen, known as caloric restriction, works in primates suggests that it improves monkeys’ health but doesn’t extend their lives. Researchers not involved with the new paper say the results are still encouraging. Although the monkeys didn’t evince an increase in life span, both studies show a major improvement in ‘health span,’ or the amount of time before age-related diseases set in. ‘I certainly wouldn’t give up on calorie restriction as a health promoter’ based on these findings, says molecular biologist Leonard Guarente of the Massachusetts Institute of Technology in Cambridge.”

Should Developers Be Sued For Security Holes?

August 23rd, 2012 08:40 admin View Comments


An anonymous reader writes “A Cambridge academic is arguing for regulations that allow software users to sue developers when sloppy coding leaves holes for malware infection. European officials have considered introducing such a law but no binding regulations have been passed. Not everyone agrees that it’s a good idea — Microsoft has previously argued against such a move by analogy, claiming a burglary victim wouldn’t expect to be able to sue the manufacturer of the door or a window in their home.”

Artificial Jellyfish Built From Silicone and Rat Cells

July 22nd, 2012 07:14 admin View Comments


ananyo writes “Bioengineers have made an artificial jellyfish using silicone and muscle cells from a rat’s heart. The synthetic creature, dubbed a medusoid, looks like a flower with eight petals. When placed in an electric field, it pulses and swims exactly like its living counterpart. The team now plans to build a medusoid using human heart cells. The researchers have filed a patent to use their design, or something similar, as a platform for testing drugs (abstract). ‘You’ve got a heart drug?’ says Kit Parker, a biophysicist at Harvard University in Cambridge, Massachusetts, who led the work. ‘You let me put it on my jellyfish, and I’ll tell you if it can improve the pumping.’” The video that accompanies the text is at once beautiful and creepy.

Ask Dr. Ramsey Faragher About Navigation/Positioning Technology

July 6th, 2012 07:58 admin View Comments


Dr. Ramsey Faragher graduated from the University of Cambridge in 2004 with a first-class degree in Experimental and Theoretical Physics. He then completed a PhD in 2007 at Cambridge in Opportunistic Radio Positioning under the direction of Dr. Peter Duffett-Smith, a world expert in this field. He is now a Principal Scientist at the BAE Systems Advanced Technology Centre specializing in positioning, navigation, sensor fusion and remote sensing technologies in the land, air, sea and space domains. We recently covered his NAVSOP project, an advanced positioning system that exploits existing transmissions such as Wi-Fi, TV, radio and mobile phone signals, to calculate the user’s location to within a few meters. Dr. Faragher has graciously agreed to answer any questions you may have about NAVSOP, the future of GPS, or what a theoretical physicist puts on his business card. Ask as many questions as you like, but please confine your questions to one per post.
