| Chip and PIN 'not fit for purpose', says Cambridge researcher |
 University of Cambridge security expert Professor Ross Anderson has blasted the EMV system used worldwide for credit and debit card transactions, and known in the UK as Chip and PIN, after his research team discovered a serious vulnerability. The group were able to carry out purchases using a card, even without knowing the associated personal identification number (PIN), by using a "man-in-the-middle" attack.

| Chicago Metra considers selling naming rights for train lines, stations |
Chicago's Metra is currently considering the possibility of selling the naming rights to its train stations, rail lines, and even bridges to generate more revenue.
The regional rail system for Chicago and its surrounding suburbs has been experiencing revenue shortfalls, along with other public transportation agencies such as the Chicago Transit Authority and Pace. They all rely on sales taxes and fares to fund their services, but the recent recession has reduced sales tax revenues, and unemployment has caused ridership to fall. Compared to 86.8 million trips in 2008, Metra reported that only 82.3 million trips were provided in 2009. As spokeswoman Judy Pardonnet said, "We're looking at any opportunity to increase non-fare revenue."

| Airborne laser successfully destroys ballistic missile |
The United States Missile Defense Agency have announced that their airborne laser system has successfully shot down a ballistic missile for the first time. In a test on Thursday the "Airborne Laser Testbed" (ALTB), a modified Boeing 747-400F, detected a boosting short-range missile and tracked it using a low-energy laser. A second low-energy laser was used to measure and compensate for atmospheric disturbance, before the aircraft's High Energy Laser was used to destroy the target.

| World-record wind speed confirmed |
 Scientists at the World Meteorological Organization confirmed this week that Cyclone Olivia in April 1996 produced gusts clocking in at 253.5 mph (408 km/h), the highest non-tornadic winds ever recorded.
The gust, recorded at Barrow Island, Australia, shattered the previous record of 231 mph (372 km/h), set on Mount Washington in the United States in April 1934. However, this record stands for the western and northern hemispheres.

| Scientists improve cancer research techniques |
 Researchers at the University of Oxford, England, have published details of an improved method for growing cancer stem cells in the laboratory. They hope that the news will lead to faster progress in developing cancer treatment drugs.
Learning how to tackle cancer stem cells is important for scientists because these cells may be the reason that tumours grow back after standard treatments such as chemotherapy or radiotherapy, as they can self-replicate or develop into other cell types. Trevor Yeung, one of the researchers from the Weatherall Institute of Molecular Medicine, explained the importance of tackling cancer stem cells: "It's like trying to weed the garden. It's no good just chopping off the leaves, we need to target the roots to stop the weeds coming back."

| US researchers increase tobacco's oil production for biofuel use |
A team of researchers from the Thomas Jefferson University's Biotechnology Foundation Laboratories (BFL) in the United States have managed to increase the amount of oil produced by tobacco leaves. Tobacco oil can be very efficiently converted to biofuel, but most oil is located in the seeds, which the plant does not produce many of.
Tobacco seeds produce around 40% oil per dry weight but a crop of the plant yields only around 600kg of seeds per acre. The leaves have an oil content of around 1.7–4% oil per dry weight. The oil has previously been tested for powering diesel-fueled vehicles and can be more efficiently converted than the product of many other crop plants.

| NASA flyby of Saturn moon Titan produces first image of liquid on another world |
 NASA have revealed that a flyby of its probe Cassini past Titan, a moon of Saturn, has produced a historic image: the first photograph showing liquid on a world other than our own.
The picture shows a "specular reflection" from an extremely smooth surface, in this case a liquid. Cassini has been trying to spot one since arriving in 2004, and in 2008 used infrared data to prove that there were liquid methane lakes down there. The northern hemisphere has only been visible since August 2009, as before then it was covered by winter weather. Most of Titan's lakes are in the north.

| Hubble telescope spots oldest galaxies ever seen |
American and European scientists say the upgraded Hubble space telescope has spotted the oldest galaxies ever seen. The images were taken with the telescope's new Wide Field Camera 3 (WFC3) in August this year.
The galaxies are about 13 billion light years from Earth, meaning they formed less than one billion years after the Big Bang — the cosmological model of the initial conditions and subsequent development of the universe.

| American botanist Lou Jost discovers world's smallest orchid |
American botanist Lou Jost, one of the world's leading orchid hunters, has discovered the smallest orchid in the world among the roots of a larger plant in a nature reserve in Bolivia, South America. The 2.1mm wide flowers have transparent petals, which are only one cell thick. The finding tops the previous record of Platystele jungermannioides with 2.5mm flowers.
Lou Jost discovered the new species accidentally, looking at a bigger plant from the Cerro Candelaria reserve in the eastern Andes. The reserve was created by a British organisation World Land Trust in partnership with Fundacion EcoMinga, for which the discoverer works. In fact, Ecuador is the place of discovery of more than 1,000 new species of orchids in the past century.

| LHC sets new particle energy acceleration record |
The world's Large Hadron Collider accelerated its protons to an energy of 1.18 TeV at 00:44 GMT+1 today. This set a new world record, surpassing the 0.98 TeV record set at the Fermi National Accelerator Laboratory's Tevatron collider, which was commissioned in Chicago in 2001. The event came ten days after the LHC collider restart.
Yesterday at 20:48 UTC, one proton beam was accelerated to 1050 GeV (1.05 TeV) in LHC. Three hours later, the next record was set by two beams of opposite direction, 1.18 TeV each.

| 2010 Sakurai Prize awarded for 1964 Higgs Boson theory work |
In recognition for the discovery of the Higgs Boson and Higgs mechanism, the American Physical Society has awarded the 2010 J. J. Sakurai Prize for Theoretical Particle Physics to Drs. C. R. Hagen, University of Rochester; G. S. Guralnik, Brown University; Tom Kibble, Imperial College London; Robert Brout, Université Libre de Bruxelles; François Englert, Université Libre de Bruxelles; and Peter Higgs, University of Edinburgh, Emeritus.
The 2010 prize was awarded “For elucidation of the properties of spontaneous symmetry breaking in four-dimensional relativistic gauge theory and of the mechanism for the consistent generation of vector boson masses.” The J. J. Sakurai Prize will be presented at the APS 2010 meeting in Washington, DC at a special Ceremonial session in February 2010.
