Algorithm identifies top ten technology news trend setters

July 5, 2012

trend_business_insider

Berlin Institute of Technology researchers studied the problem of trend-setting among news sites to determine which websites lead the news coverage and which ones merely follow, Technology Review Physics arXiv Blog reports.

They took a snapshot of the words generated by 96 technology news websites at any instant in time and compared them to the words generated by one of these websites at an earlier time.

This allowed them… read more

Algorithmic stock trading rapidly replacing humans

September 9, 2011

Algorithmic trading (high frequency trading) is rapidly replacing human decision making, according to a UK government panel, which warned that the right regulations need to be introduced to protect stock markets.

Algorithms identify and track the most important privately-held technology companies

Quid Map

A startup called Quid has developed algorithms that analyze Internet-based data from corporations to make fast-moving technology developments visible, navigable, and understandable.

Quid has built a data set combining information about firms that succeeded and sank, patent documents, government grants, help wanted advertisements, and tweets. Its algorithms use the collection of information to analyze the prospects of around 35,000 firms and research groups working on new technologies.… read more

Alice Chatbot Wins for Third Time

September 20, 2004

Richard Wallace’s Alice chatbot program beat three other finalists to take the 2004 bronze metal for the Loebner Prize competition.

The bronze metal goes to the program best able to maintain a life-like conversation. No program has won gold or silver metals, which will go to programs able to convince half the judges that the program is a human, either via video (gold) or text (silver).… read more

Alien Animal Planet

February 6, 2006

Computer models created by NASA and SETI Project researchers have helped identify which stars among the universe’s 70 sextillion are most likely to support life.

They used two scenarios formulated by the SETI Project: a planet orbiting a sun close enough to keep water from freezing out, yet far enough away to avoid evaporation and a moon orbiting a gas giant and warmed by twin suns.

Then life… read more

Alien astronomers could discern Earth’s features

December 26, 2007

Aliens spying on us from another star system might be able to discern continents and oceans on our planet by plotting the fluctuation in brightness as sunlight falls on different surface features such as forests, deserts and seas.

‘Alien code’ leads to faster vaccines

June 5, 2006

Four years ago, Eckard Wimmer scared the world by making the polio virus from scratch. This prompted fears that terrorists would copy his methods to create deadly viruses of their own. Now his team at Stony Brook University in New York are using the same method to create weakened viruses that could speed up the development of new vaccines.

Alien Contact More Likely by ‘Mail’ Than Radio, Study Says

September 2, 2004

A new study suggests it is more energy-efficient to communicate across interstellar space by sending physical material than beams of electromagnetic radiation.

Beams of radiation are cone-shaped and grow in size as they travel outward, meaning the great majority of their energy is wasted.

A far more energy-efficient — although slower — way of communicating over great interstellar distances is to send a physical object, which can hold… read more

Alien hunters ‘should look for artificial intelligence’

August 23, 2010

allentelescopearray

The odds favor detecting alien AI rather than biological life because the time between aliens developing radio technology and artificial intelligence would be short, says SETI Institute senior astronomer Seth Shostak.
He also says that artificially intelligent alien life would be likely to migrate to places where both matter and energy — the only things he says would be of interest to the machines — would be in plentiful supply.… read more

‘Alien’ message tests human decoders

January 9, 2002

A message that will be broadcast into space later in 2002 has been released to scientists worldwide, to test that it can be decoded easily. The researchers who devised the message eventually hope to design a system that could automatically decode an alien reply.

The new binary message can be downloaded from the CETI home page. The project leaders hope that it will be transmitted by… read more

Alien Planets Show Themselves for First Time

March 23, 2005

Astronomers have seen light from extrasolar planets for the first time.

The planets, in the constellations constellation Pegasus and Lyra, were discovered by comparing measurements of infrared light made while the planet and star were both visible and while the planet was hidden behind the star.

Aligned nanotube swarms may lead to nanoprocessors

April 24, 2008

Duke University chemists have found a way to grow swarms of long, straight cylinders only a few atoms thick in very large numbers by using the crystal structure of a quartz surface as a template.

These single-walled carbon nanotubes also follow parallel paths as they grow, so they don’t cross each other to potentially impede electronic performance. Carbon nanotubes can act as semiconductors and could thus further scale-down circuitry… read more

All Bio Systems Are Go

October 22, 2004

Systems biologists are pushing the envelope of preventive medicine through research centered on the interactions of the thousands of pieces of DNA, RNA and proteins that network together in each cell of our body.

According to its proponents, systems biology will revolutionize medicine, transforming it from something that is mainly reactive into something that is predictive and will eventually prevent diseases getting hold in the first place.

The… read more

All Done With Mirrors: NIST Microscope Tracks Nanoparticles In 3-D

March 11, 2008
 Four side views of a nanoparticle floating in solution (left) are reflected up. A microscope above the well sees the real particle (center, right) and four reflections that show the particle

A new microscope design allows nanotechnology researchers at the National Institute of Standards and Technology (NIST) to track the motions of nanoparticles in solution as they dart around in three dimensions.

The technology may lead to a better understanding of the dynamics of nanoparticles in fluids and, ultimately, process control techniques for “directed self-assembly.” This capitalizes on physical properties and chemical affinities of nanoparticles in solutions to… read more

All eyes switch to ‘smart’ TVs

January 9, 2008

The shift towards internet-connected or “smart” TVs is an important trend identified by CES show in Las Vegas, driven by consumer desire to view YouTube videos and other digital content On TV sets, directly from the Internet or home networks.
