NASA Detects Nearby Mystery Explosion 329

starexplorer2001 writes "Space.com is reporting that NASA has detected a 'totally new' mystery explosion near our galaxy." From the article: "The event, detected Feb. 18, looks something like a gamma-ray burst (GRB), scientists said. But it is much closer--about 440 million light-years away--than others. And it lasted about 33 minutes. Most GRBs are billions of light-years away and last less than a second or just a few seconds."

Online Artificial Gene Design 100

massivefoot writes to tell us New Scientist is reporting that researchers at Johns Hopkins University School of Medicine have released a new software suite, GeneDesign, that helps to simplify the steps in designing artificial DNA. From the article: "These key steps include translating proteins and amino acids - the building blocks which make proteins - backwards into a DNA sequence. Or the software can manipulate simulated DNA "codons" which can code for an amino acid. DNA codons are made of sets of three nucleotides - the fundamental molecules which link together to form a DNA chain."

VisiCalc Creator Developing WikiCalc 139

An anonymous reader writes "ZDNet has an article about a new wiki that is trying to combine the collaboration of wiki technology and the data manipulation attributes of a spreadsheet. The creator of VisiCalc, Dan Bricklin, is working on an alpha version of WikiCalc for sometime late in February." From the article: "'It holds a lot of promise, both because it's using the spreadsheet metaphor, which is the one thing people know for working with quantitative information and because 'there's nobody better in the world to build this thing,' said Ross Mayfield, CEO of collaboration software maker SocialText. To Mayfield, WikiCalc is the answer to a problem that has been percolating for some time in the world of IT. That is, he said, that spreadsheets have traditionally been a single-user application screaming for functionality that could let multiple people edit data quickly and easily. "
