Collision in the making between self-driving cars and how the world works

January 26, 2012

Robot Car

Questions of legal liability, privacy and insurance regulation self-driving vehicles have yet to be addressed, and such challenges might pose far more problems than the technological ones.

Should the police have the right to pull over autonomous vehicles?

Human drivers frequently bend the rules by rolling through stop signs and driving above speed limits; how would a polite and law-abiding robot vehicle fare against such competition?

Collision Course: Beating Moore’s Law by 2006 will take teamwork

February 15, 2002

CERN’s Large Hadron Supercollider will begin generating more than 10 million gigabytes of data each year when it becomes operational in 2006 — beyond the capabilities of any computer CERN scientists had at their disposal, or any supercomputer that could be built. The solution: the European DataGrid.The European DataGrid is an ambitious project based on an emerging distributed-processing technology known as grid computing. Instead of relying on mainframe makers like… read more

Colliding Particles Can Make Black Holes

January 25, 2010

Princeton University scientists have calculated the gravitational interactions between colliding particles modeled as black holes and found that a black hole formed if two particles collide with a total energy of about one-third of the Planck energy.

While the Planck energy is a quintillion times higher than the LHC’s maximum, if space actually has more dimensions (predicted by certain theories) that are curled into little loops too small to… read more

Colleges see the future in technology

September 13, 2006

Cutting-edge videogame and artificial intelligence technology are on the way to provide more individualized instruction.

Some of the most futuristic devices could even monitor students’ brainwaves to keep track of how they’re learning.

College for all? Experts say not necessarily

May 17, 2010

With rising student debt, stagnant graduation rates, a struggling job market flooded with overqualified degree-holders, and unemployment rate for college graduates trailing the rate for high school graduates, the notion that a four-year degree is essential for real success is being challenged by a growing number of economists, policy analysts and academics.

College for $99 a Month

September 7, 2009

The next generation of online education could be great for students — and catastrophic for universities, as a great deal of money is going to abruptly melt out of the higher education system, just as it has in scores of other industries that traffic in information that is now far cheaper and more easily accessible than it has ever been before, says Kevin Carey, the policy director of Education Sector,… read more

Collective memory

December 10, 2010


As computing power continues to move from the desktop to portable devices, the nature of communications networks will change radically. A network in which devices are regularly being added and removed, and where the strength of the connections between the devices fluctuates with their movement, requires much different protocols from those that govern relatively stable networks, like the Internet.

In a paper appearing in the December issue of… read more

Collective intelligence in small teams

October 1, 2010

A new study co-authored by MIT researchers documents the existence of collective intelligence among groups of people who cooperate well, showing that such intelligence extends beyond the cognitive abilities of the groups’ individual members, and that the tendency to cooperate effectively is linked to the number of women in a group.

Many social scientists have long contended that the ability of individuals to fare well on diverse cognitive tasks… read more

Collective Intelligence 2.0

January 27, 2006

Nova Spivack has proposed a “collective self-awareness” Web service that is “like a ‘Google Zeitgeist’ on steroids, but with a lot more real-time, interactive, participatory data, technology and features in it.

“The goal is to measure and visualize the state of the collective mind of humanity, and provide this back to humanity in as close to real-time as is possible, from as many data sources as we can handle.… read more

Collecta Launches *Really* Real-Time Search Engine

June 19, 2009

Collecta draws information streams from blogs using Wordpress, news services, social aggregation sites, Flickr, and Twitter to provide what it claims is the first truly real-time search engine.

Collaborative learning for robots

New algorithm lets independent agents collectively produce a machine-learning model without aggregating data

Researchers from MIT’s Laboratory for Information and Decision Systems have developed an algorithm in which distributed agents — such as robots exploring a building — collect data and analyze it independently. Pairs of agents, such as robots passing each other in the hall, then exchange analyses.

In experiments involving several different data sets, the researchers’ distributed algorithm actually outperformed a standard algorithm that works on data aggregated… read more

Cold viruses point the way to new cancer therapies

Salk findings on cold virus proteins may spur new cancer treatments
October 22, 2012

Salk researchers discovered that a small protein produced by cold viruses disables large cellular machines involved in growth, replication and cancer. These proteins accomplish this by forming a three-dimensional web inside a cell's nucleus (yellow) that traps these components. The findings point the way to new ways to target and destroy tumors. (Credit: Salk Institute for Biological Studies)

Cold viruses generally get a bad rap — which they’ve certainly earned — but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ally in the fight against cancer.

Adenovirus, a type of cold virus, has developed molecular tools — proteins — that allow it to hijack a cell’s molecular machinery,… read more

Cold Virus Zaps Brain Tumors

May 6, 2003

A genetically altered common cold virus worked so well in destroying the most lethal type of brain tumor in experiments with mice that researchers want to take the treatment to people next year. The scientists implanted the human glioblastomas inside the brains of mice, and found only empty cavities and scar tissue where the tumors once were.

Lead researchers cautioned that the dramatic results don’t assure the virus will… read more

Coherent Computing: Making qubit superpositions in superconductors last longer

August 9, 2002

Research teams have made critical breakthroughs in developing quantum computers. The Quantronics group at the Atomic Energy Commission (CEA) in Saclay, France, and Siyuan Han’s laboratory at the University of Kansas reported qubit chip designs with coherence times at least 100 times as great as those achieved before. Investigators at the National Institute of Standards and Technology (NIST) in Boulder, Colo., have come up with a design that they think… read more

Cognitive-stimulation experiment suggests new tools for healthy brain aging

May also have a "preventive and therapeutic role in association with early AD-type neurodegeneration"
January 8, 2016

DMN connections

Neuroscientists in Italy and the U.K. have developed cognitive-stimulation exercises and tested them in a month-long experiment with healthy aging adults. The exercises were based on studies of the brain’s resting state, known as the “default mode network”* (DMN).

In a paper published in Brain Research Bulletin, the researchers explain that in aging (and at a pathological level in AD patients), the posterior (back) region of the DMN in the… read more
