dracodraconisSpam is 30 years old - on May 2nd, according to New Scientist. Found on Slashdot.
Bill to prohibit discrimination based on genetic test results moves ahead - The US congress reached an agreement that has allowed a proposed bill to prohibit discrimination by employers and insurers based on genetic tests to proceed. Apparently even the concerns raised by the President have even been addressed and it is expected that the bill will pass both the House and Congress to become law eventually. Found on Slashdot.
Cyanbacteria modified to produce cellulose and sugar for biofuel production - Two researchers have tweaked the genes of blue-green algae to produce a gel-like form of cellulose that is easy to convert into sugars for biofuel production, as well as large amounts glucose and sucrose. The bacteria could be grown in vats on land unsuitable for food production using water that is unsuitable for human use. Found on Slashdot.
Artificial spider's silk spun on chip - German researches have developed a way to spin artificial spider silk using a glass chip filled with tiny ducts that emulates the function of a spider's silk-producing ducts.
Web-like solar sail proposed for unmanned deep space missions - Finnish researchers propose using a novel type of solar sail to provide thrust for the next generation of spacecraft headed out of the solar system. The sail consists of a 100 20-kilometer long strands of wire which are then positively charged. As a result, they spread out in mutual repulsion to form a broad web, as well as repel the positively charged ions emitted by the sun to provide thrust. Within a year they could propel a 200-kg spacecraft to a speed of 30-km/second.
