1. Photonic chip breaking the terabit-per-second barrier. Researchers from Australia, Denmark, and China have combined efforts to show the feasibility of terabit-per-second Ethernet over fiber-optic cables. The solution involves a photonic chip that uses laser light for switching signals, and a form of the exotic material type, chalcogenide. One of the key breakthroughs researchers made …
200 million megaton of explosions will not kill the biosphere. The current nuclear arsenal will not kill all humans and the pattern of nuclear explosions for a nuclear war between the largest nuclear powers will not destroy civilization, let alone kill all people or even half of all people. The greatest risks from a total …
A new urine test that is about 80-92% accurate could allow for early detection of coronary artery disease. Coronary artery disease (CAD) is responsible for most of the 1.5 million heart attacks that occur in the United States each year. A cheap and simple test for biomarkers would allow for early detection and monitoring of …
NASA looks to be developing larger (12-40KW) radioisotope thermoelectric generators for the moon’s surface. Hopefully NASA finishes this work as they have a history of starting big RTG projects and not completing them. Also, it probably would be better to use the Hyperion uranium hydride reactor instead, which has been covered extensively on this site …
North Dakota June 2008 daily production is now over 166,000 barrels of oil per day which is 10,000 barrels per day more than in May 2008 North Dakota is hitting transportation issues getting the oil out of the state. However, oil can still be moved out it just costs more to do it. North Dakota’s …
SUNRGI’s “concentrated photovoltaic” system relies on lenses to magnify sunlight 2,000 times, letting it produce as much electricity as standard panels with a far smaller system. They say they’ll start producing solar panels by mid-2009 that will generate electricity for about 7 cents a kilowatt hour, including installation. Update: Very cool: Dilbert blog [Scott Adams] …
Many people who discess the enlightenment and social discuss the power of the masses versus the power of the lite. The supporters of the Enlightenment do not want “the elite” to roll back society to a more fuedal looking power structure. Who are the elite and where does real power reside ? Newsweek has a …
The concept of a memory device based on self-organized quantum dots (QDs) is presented, enabling extremely fast write times, limited only by the charge carrier relaxation time being in the picosecond range. (from Applied Physical letters) [potentially one thousand times faster than current computer memory] For a first device structure with embedded InAs/GaAs QDs, a …

A new lab on a chip — slightly more than 1.5 square inches in area — detected circulating cancer cells in 115 of 116 blood samples from patients with metastatic cancer for a sensitivity of 99.1%, according to Daniel Haber, M.D., director of the Massachusetts General Hospital Cancer Center, and colleagues. I have proposed widespread …
