Sun To Replace Computer Wires With Leaser beams To Connect Processor Chips

Sun is trying to replace the wires between computer chips with laser beams to eliminating a bottleneck. For decades, the semiconductor industry has broken silicon wafers into smaller chips to improve manufacturing yields. From the article:

Sun Microsystems is trying to do for computing what all the kingâ€™s horses and men failed to do for Humpty Dumpty. For decades, the semiconductor industry has broken silicon wafers into smaller chips to improve manufacturing yields.
Now Sun has found a way to reconnect the chips so they can communicate with each other at such high speeds that computer designers can build a new generation of computers that are faster, more energy-efficient and more compact.
The computer maker, which is based in Santa Clara, Calif., plans to announce on Monday that it has received a $44 million contract from the Pentagon to explore the high-risk idea of replacing the wires between computer chips with laser beams.

I’m not an expert in electricity or electronics but on paper a laser should move as fast as energy. I really hope this will to improve speed :) Each chip would be able to communicate directly with every other chip via a beam of laser that could carry billions of bits of data a second.

Fight Global Warming With Methane-Eating Bacteria

Global warming refers to the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation.Global warming refers to the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation.

The geographic distribution of surface warming during the 21st century calculated by the HadCM3 climate model if a business as usual scenario is assumed for economic growth and greenhouse gas emissions. In this figure, the globally averaged warming corresponds to 3.0 Â°C (5.4 Â°F).

Now, NEW Zealand scientists hope a newly discovered bacterium that eats methane could ultimately help counter a key global warming gas.

The bacterium was discovered living about 30cm below the ground in the hot, acidic environment at Hells Gate in Rotorua, a geothermal area.

Remembering Chernobyl Nuclear Nightmares

Twenty years ago yÃ¢â‚¬â„¢day, the world’s worst nuclear disaster blew the roof off the Chernobyl Nuclear Power Plant in Ukraine. For many people, the event seems far off, and much has changed in the decades since. But for those who live in Chernobyl and other former Soviet towns, afflictions from nuclear accidents and experiments remain an intimate part of their lives.

I hope human learn something from it. There is still great dangerous because of Nuclear bombs.

Photographer Robert Knoth and reporter Antoinette De Jong have traveled through the Ukraine, Urals, Kazakhstan, and Siberia to capture, in searing black-and-white portraits, the way that nuclear radiation has forever altered the humans who face it
