Creating more human-like robots

November 10, 2004

Purdue University is leading an NSF-funded project to enable humanoid robots to move more like people and adapt quickly to new situations so they can complete a variety of tasks they weren’t specifically programmed to perform.

The researchers will record human movements in three dimensions, using sensors placed around certain body parts, such as fingers and arms, as a person moves in a low-level magnetic field. They will use… read more

A team led by University of Arizona (UA) optical sciences professorĀ Nasser Peyghambarian has developed a new type of “holographic telepresence” that allows remote projection of a three-dimensional, moving image without the need for special eyewear such as 3D glasses or other auxiliary devices.

The technology is likely to take applications ranging from telemedicine, advertising, updatable 3D maps and entertainment to a new level.

UFO cult endorses brain transplants

April 10, 2001

RAEL, founder of Clonaid, the first human cloning company, and self-described “Messenger of Infinity” and “brother of Jesus,” announced today he has given his support to Professor Robert White of Cleveland, Ohio, who hopes to perform brain and human head transplants.

White recently announced he has transplanted a whole monkey’s head onto another monkey’s body. The animal survived for some time after the operation.

Clonaid is owned by… read more

A Quantum Memory Leap

January 23, 2009

University of Maryland and University of Michigan researchers have announced the ghostly transfer of the quantum state of a single ion to another one a meter away for several seconds.

Unlike current experiments, this scheme for “quantum teleportation” could buy enough time for manipulations that allow long-distance communications that are immune to eavesdropping, or for computations that exploit the quantum mechanics to perform blazing fast calculations.

Eight-million-year-old bug is alive and growing

August 8, 2007

An 8-million-year-old bacterium that was extracted from the oldest known ice on Earth is now growing in a laboratory, claim researchers.

If confirmed, this means ancient bacteria and viruses will come back to life as ice melts due to global warming. This is nothing to worry about, say experts, because the process has been going on for billions of years and the bugs are unlikely to cause human disease.

Report: Fast-Internet Use Doubles in U.S.

November 23, 2004

The number of Americans using fast Internet connections doubled from 2001 through late 2003. according to a Commerce Department National Telecommunications and Information Administration report.

Some experts said growth was disappointing, far behind countries that include South Korea, Taiwan and Canada. The report also identified troubling figures for use or availability of high-speed Internet services among blacks, Hispanics and people in rural areas.

35 hours of video per minute uploaded to YouTube

November 12, 2010

(YouTube blog)

More than 35 hours of video are uploaded to YouTube per minute, or 50,400 hours uploaded every day — the equivalent of more than 176,000 full-length Hollywood releases every week.

Here are some of the factors contributing to the growth:

  • The time limit for videos uploaded by usersĀ increased by 50% from 10 to 15 minutes.
  • The upload file size increased over the last few

A Simple Plan

May 2, 2001

The Simputer (Simple Inexpensive Mobile Computer), a computer priced and designed for the billions of people without access to computers, has been developed by India-based Simputer Trust.

The prototype features Intel chip, 32 MB of RAM, 16 MB of flash memory, Linux OS, multilingual text-to-speech, picture-based touch-sensitive screen, Palm-like grafitti writing and Internet access via phone line, with a target retail price of $200.

Organic computing takes a step closer

January 30, 2009
(Science)

University of Manchester scientists have shown that by adding hydrogen atoms to the surface of graphene, it can be tuned to be conductor, insulator, or anything in between, paving the way for a sheet of graphene to be transformed into a working chip with conductive interconnections and semiconducting transistors simply by changing its chemistry in different areas.

Using a single material could simplify construction and allow near-seamless… read more

Ultrafast quantum computer uses optically controlled electrons

August 16, 2007

Stanford University scientists have designed a scheme to create one of the fastest quantum computers to date, using light pulses to rotate electron spins, which serve as quantum bits.

The Scientific Consensus on Climate Change

December 8, 2004

There is a scientific consensus on the reality of anthropogenic (human-caused) climate change, according to reports from several professional societies.

‘Silent’ DNA Speaks Up

May 22, 2001

Biologists have broken through what was considered an impermeable barrier that kept half the genes in some cells “silent.” By moderately raising the temperature of cells, heated genes reached 500 times their normal rate of expression, which could lead to better understanding of cellular processes involved in aging, fever and toxicity.

India’s $10 laptop: Too good to be true

February 5, 2009

India’s much-hyped plan to build a $10 laptop has been exposed as a massive exaggeration — it’s a 2GB hard drive with wireless capabilities.

New Visualization System at UC San Diego

August 23, 2007

Engineers at the University of California, San Diego have constructed the highest-resolution computer display in the world — with a screen resolution up to 220 million pixels.

The system, located at the UCSD division of the California Institute for Telecommunications and Information Technology (Calit2), can deliver real-time rendered graphics simultaneously across 420 million pixels to audiences in Irvine and San Diego.

The engineers are planning half… read more

‘Polymeal’ could reduce cardiovascular disease by more than 75%

December 20, 2004

Researchers suggest that a diet heavy in the “Polymeal” — a set of foods known to reduce cardiovascular disease events or modify risk factors — could lower cardiovascular disease by 75% or more.

The combination of the components of the Polymeal — wine, fish, dark chocolate, fruits and vegetables, almonds, and garlic — would reduce the risk of cardiovascular disease events by 76%. For men, taking the Polymeal daily… read more
