The Sun lets loose a huge explosion

June 8, 2011

(Credit: NASA/SDO)

On June 7, the Sun released a solar flare coupled with a prominence (a physical eruption of gas from the surface). This event blasted something like a billion tons of material away from the sun.

While it started from a small region on the Sun’s surface, it quickly expanded into a plume easily as big as the Sun itself — possibly over a million kilometers across.

The Super Network

August 24, 2005

Every major cable company is making investments to allow TV to be distributed over the Internet, giving you access to 31 million hours pf programming per year. And then there’s this year’s 36-fold explosion in consumer-generated video on the Internet.

Yahoo! is working with SBC and Microsoft on an IPTV/fiber-to-the-curb initiative called Project Lightspeed that uses Yahoo! software to deliver video-on-demand, instant messaging, photo collections, and music.

The Supercomputing Speed Barrier

The Technicolor Brain

November 1, 2007
Genetically engineered "brainbow" mice express random combinations of cyan, yellow, and red fluorescent proteins in nerve cells.

Researchers at Harvard University have developed a new method for setting the brain aglow in a rainbow of colors.

The ability to paint individual brain cells with such a broad palette will allow neuroscientists to explore neural circuits like never before.

Jean Livet, Jeff Lichtman, and their collaborators at Harvard genetically engineered mice to carry numerous copies of genes that code for fluorescent proteins of three… read more

The technologies in IBM’s Watson used for drug research

December 8, 2011

The ingredients that went into Watson, including speech recognition, machine learning, natural-language processing, data mining and ultra-fast in-memory computer hardware, are steadily finding their way into IBM products, New York Times Bits reports.

For example, WellPoint, the big health insurer, is trying out a system that uses Watson-style software to reduce redundant medical tests.

As a byproduct of its research, IBM is also adding to a… read more

The theological robot

February 8, 2005

In her new book, “God in the Machine,” self-described robotics theologian Anne Foerst seeks to bridge the divide between religion and AI research–by arguing that robots have much to teach us about ourselves and our relationship with God.

“Like babies, or Alzheimer’s patients, humanoid robots don’t tell their own stories, but they play a role in our lives so we include them in our narrative structures,” she says. “This… read more

Meet the groundbreaking new encryption app set to revolutionize privacy and freak out the feds
February 6, 2013


For the past few months, some of the world’s leading cryptographers have been keeping a closely guarded secret about a pioneering new invention. Today, they’ve decided it’s time to tell all, Slate Future Tense reports.

Back in October, the startup tech firm Silent Circle ruffled governments’ feathers with a “surveillance-proof” smartphone app to allow people to make secure phone calls and send texts… read more

The Time Is Now: Bust Up the Box!

October 5, 2005

For decades, increases in the speeds of computer networks trailed the exponentially accelerating speed of microprocessor chips. Now the balance between the power of computer processing and networking has fundamentally reversed, and the rapid rise of transmission speeds is beginning to have a revolutionary impact on how computers are used and what they can do, as computing becomes distributed on a global basis.

The new epoch of computing has… read more

The tiny, lethal weapon that viruses use to kill bacteria

April 13, 2012


EPFL scientists have measured a one-nanometer needle-like tip that some viruses use to attack bacteria.

A family of bacteriophage viruses called φ92, which attacks salmonella and coliform bacteria, uses a needle-like tip that pierces its victim’s membrane. EPFL scientists have measured this miniscule weapon at a single nanometer. This discovery will allow researchers to better understand the attack strategy used by bacteriophages, which are being intensively studied for their… read more
