A supercomputer to map the cosmos

January 22, 2013

eso_alma

A new petascale supercomputer built to study the universe is one of the fastest calculating machines in the world, and certainly the fastest of its kind.

The supercomputer is part of ALMA, a new radio telescope that is claimed to be “largest ground-based astronomical project in existence,” HPC Wire reports.

The ALMA (Atacama Large Millimeter/submillimeter Array and “soul” in Spanish) radio telescope is a… read more

A Supercomputer to Save Earth?

December 17, 2002

“Running 35.6 trillion calculations per second, the Earth Simulator is the fastest supercomputer in the world…According to the Department of Energy, the Earth Simulator has put American scientists at a 10- to 100- fold disadvantage in weather studies. And there are much deeper implications….”

A superconductor advance using ‘superatoms’

February 27, 2015

Superconductivity is the ability to transmit electricity without resistance (credit: USC/Original image/DC Comics Mystery in Space #56, December 1959)

USC scientists may have discovered a family of superconductor materials called superatoms that could lead to room-temperature supercomputers.

A team led by Vitaly Kresin, professor of physics at the USC Dornsife College of Letters, Arts and Sciences, found that aluminum “superatoms” — homogenous clusters of atoms — appear to form Cooper pairs of electrons (one of the key elements of superconductivity) at temperatures around 100 Kelvin.

A Superlens That Assembles Itself

July 23, 2009
(Nature)

Korean researchers have created nanoscale lenses with superhigh resolution, using a novel self-assembly method, that can be used for ultraviolet lithography for chips, for imaging objects too tiny for conventional lenses, and for capturing individual photons from a light-emitting nanostructure called a quantum dot.

A surreal timeline: When is ‘The Matrix’?

November 7, 2003

The Associated Press has compiled an estimated timeline of the war between men and machines.

2010-60 — Humans create humanoid drone robots with Artificial Intelligence to fill jobs as construction laborers and servants.

2075 — AI programs evolve and some robots began to resent their human overlords.

“This timeline is incredibly flawed. It fails to mention the fact that ‘The One’ has been inserted into… read more

A survey of new educational technologies and methods

September 20, 2010

Learning by playing video games, the effects of exercise on learning, and replacing text books with tablet computers are among the topics in a New York Times Magazine special issue on technology in education published on Sunday September 19.

A Survival Imperative for Space Colonization

July 17, 2007

In 1993, Princeton professor of astrophysics J. Richard Gott III computed with scientific certainty that humanity would survive at least 5,100 more years. Now he has issued a wake-up call: To ensure our long-term survival, we need to get a colony up and running on Mars within 46 years.

A synthetic creation story

May 25, 2010

With last week’s announcement of the “chemical synthesis of a living organism,” what Craig Venter and his colleagues have achieved is not so much a “synthesis of life” as a semi-synthetic recreation of what we currently deem life to be, says Phillip Ball, consultant editor for Nature.

“‘Life’ in biology, rather like ‘force’ in physics, is a term carried over from a time when scientists thought quite differently, when… read more

A System for Connecting Brains to the Outside World

August 3, 2010

Dr. John Donoghue, a professor of engineering and neuroscience at Brown University, speaks with the New York Times about his studies of how human brain signals could combine with modern electronics to help paralyzed people gain greater control over their environments. He’s designed a machine, the BrainGate, that uses thought to move limbs.

Samsung is researching how to bring mind control to its mobile devices with the hope of developing ways for people with mobility impairments to connect to the world, MIT Technology Review reports.

In collaboration with Roozbeh Jafari, an assistant professor of electrical engineering at the University of Texas, Dallas, Samsung researchers are testing how people can use their thoughts to launch an application, select a… read more

A tactile glove provides subtle guidance to locate objects

October 11, 2012

tactile_glove

Researchers from the University of Helsinki Institute for Information Technology (HIIT) and the Max Planck Institute for Informatics have developed a prototype of a glove that uses vibration feedback on the hand to guide the user’s hand towards a predetermined target in 3D space.

The glove could help users in daily visual search tasks in supermarkets, parking lots, warehouses, libraries etc.

Their study shows an almost three-fold advantage… read more

A Talk with the Brain behind Blue Gene

November 9, 2001

On Nov. 9, IBM will disclose a partnership with Lawrence Livermore National Labs to work on a wide range of scientific applications for Blue Gene. This will be the world’s fastest supercomputer, being designed to operate a hundred times faster than today’s speediest machines. The objective: to simulate how proteins fold themselves into their unique patterns.
With Blue Gene, IBM is trying to set a new supercomputer speed limit –… read more

A telescope bigger than a galaxy

Astronomers have announced a view of the universe though a lens more than 500,000 light years wide, as part of a program called “Frontier Fields” to search for the first galaxies.

The “lens” is actually a massive cluster of galaxies known as Abell 2744. As predicted by Einstein’s Theory of General Relativity, the mass of the cluster warps the fabric of space around it. Starlight passing by… read more

New contact lens design may improve sight of patients with macular degeneration, switches between magnified and normal vision
July 1, 2013

telescopic contact lens

An international team of researchers led by University of California San Diego Professor Joseph Ford has created a slim, telescopic contact lens that can switch between normal and magnified vision. With refinements, the system could offer age-related macular degeneration (AMD) patients a relatively unobtrusive way to enhance their vision.

Visual aids that magnify incoming light help AMD patients see by spreading light around to undamaged parts of… read more

A telescope that sets its sights on cyber-crime

February 5, 2010

Endgame Systems of Atlanta has come up with a system called the Internet telescope that can map the physical location of computers infected with malicious software, or malware, used to run botnets (thousands of computers taken over to run malware). It can even identify the type of malware on the machine and preempt its next moves.
