• The Hayabusa spacecraft lands on 25143 Itokawa a second time and executes its sample collection sequence on the surface, successfully. JAXA officials say that with high probability the probe now holds asteroid material, which is slated to return to Earth by 2007. (BBC)

November 24, 2005

• European scientists publish a study in Science that indicates that the current carbon dioxide content of the air is higher than at any time in the last 650,000 years. The data for this study was obtained by the European Project for Ice Coring in Antarctica from analyzing air bubbles enclosed in ice. (AP/YahooNews)
• Professor Hwang Woo-suk resigns from all public posts, including that of chairman of the World Stem Cell Hub and apologises for using human eggs from his own researchers and those bought from donors for his research (BBC), (Nature)
• A new variant of the Sober virus spreads through worldwide email systems, by fraudulently claiming to originate from the United States FBI, the CIA or the German BKA. (BBC)

November 23, 2005

• JAXA officials announce that Hayabusa did land on 25143 Itokawa in its first attempt on November 19, and stayed in contact of the surface for about 30 minutes. However, it has failed to collect a sample. (AP/YahooNews)

November 21, 2005

• A PhD student from Stanford University has created a digital camera that can refocus images after they are taken by using 90,000 micro lenses which measure light direction. (Wired)

November 20, 2005

• The Spirit rover reaches one Martian year on the surface of Mars. (NASA)

November 19, 2005

• Hayabusa fails to take surface samples of 25143 Itokawa after dropping a target marker and guiding itself to a distance of 17 m to its target. At that point the spacecraft enters its safe mode for unknown reasons, and communications are interrupted for three hours. During this time it drifts but is assumed to be currently within 100 km of the asteroid. (AP/YahooNews) (AFP/YahooNews)

November 18, 2005

• Removing the Sir2 gene has revealed a potential breakthrough in ageing research; as the cells are tricked into reacting as though there is a food shortage and slowing down. This has resulted in organisms living six times longer than normal. (Guardian)
• Archaeologists in Norway discover 35 stone age settlements in southern parts of the border between Telemark and Vestfold counties; 20 of the dwellings stem from the Upper Paleolithic period, roughly 8,000 BC. Before this discovery, only six such dwellings were known in the whole of southern Norway. The excavations have been done in this exact area and time as part of the preparation for rerouting and widening European Highway E18. (This follows the standard procedure in Norway of the Inspectorate of Ancient Monuments and Historic Buildings withholding the startup of major road construction projects until proper archaeological excavations of the affected area have been performed.)

November 16, 2005

• The European Space Agency (ESA) launches two commercial satellites using the Ariane 5 ECA rocket, achieving the tenth successful launch in a row for the Ariane 5 series. With its total payload mass of about 8,000 kg (8 metric tons) this mission sets a new record. (spaceRef.com)

• The 26th TOP500 list of the world's highest-performance supercomputer installations is presented at the Supercomputing Conference (SC|05) in Seattle, Washington. The two top positions on the list are held by IBM-built Blue Gene/L systems, with no. 1 achieving a performance of more than 280 teraFLOPS—a doubling since the previous list, in June. (TOP500.Org)
• Sun Microsystems introduces its 8-core, 4-way multithreading microprocessor UltraSPARC T1 (formerly codenamed Niagara), which is the general-purpose CPU with the highest number of cores on a single chip to date. The T1 will consume about 70 watts of power, less than half that of other multicore processors. (eWEEK.com)

November 12, 2005

• The release of the Minerva robot by Hayabusa fails to deliver it onto the surface of 25143 Itokawa. Most likely the release command was incorrectly timed, and the robot left the gravity field of the asteroid. (MSNBC)

November 11, 2005

• Sony stops using the XCP copy protection technology after it is found that virus programs exploit it as a "backdoor", and previous negative reactions by the public. (AP/CBSNews)
