Five Christmas Presents That Could Change Your Life
A chair with no back; a helmet that’s not really there; a ‘Star Trek’-style replicator. The Christmas gifts of the future are already here.
The helmet
The ‘invisible’ bike helmet
In Spring 2005, Anna Haupt and Terese Alstin, two Swedish industrial designers, were studying at Lund University when they became interested in cycle safety. The catalyst for their thesis project – the “Hövding” invisible bike helmet – was the introduction of new tough laws in Sweden that made bicycle helmets compulsory for children under the age of 15.
According to their research, 40 people die and 30,000 are injured each year in cycling accidents in Sweden alone, but the vast majority of cyclists do not wear helmets. The reason?
“Bicycle helmets are bulky and impractical to carry around when you’re not on your bicycle,” says Haupt. “People think bicycle helmets look hideous and make them look silly. They ruin your hair and you can’t get a hat on underneath.”
Their “invisible” solution has to be, well, seen to be believed. It takes the form of a scarf-like collar that zips up around the neck and is available in different coloured and patterned sleeves. When sensors pick up “abnormal movements of a bicyclist in an accident”, an airbag hood pops out instantaneously, protecting the head.
Amazingly, the Hövding complies with safety requirements. It is, according to the designers, “a practical accessory [that] will save your life”. It is available now, for the price of ¤499 (£400). Sleeves cost an additional ¤59 (£47.50). hovding.com

The Dark Energy Survey
 |
| The Dark Energy Survey (DES) is designed to probe the origin of the accelerating universe and help uncover the nature of dark energy by measuring the 14-billion-year history of cosmic expansion with high precision. More than 120 scientists from 23 institutions in the United States, Spain, the United Kingdom, Brazil, and Germany are working on the project. This collaboration is building an extremely sensitive 570-Megapixel digital camera, DECam, and will mount it on the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory high in the Chilean Andes. Starting in Sept. 2012 and continuing for five years, DES will survey a large swath of the southern sky out to vast distances in order to provide new clues to this most fundamental of questions. The National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign will operate a sophisticated data management pipeline for DES. DES will gather an enormous amount of data, capturing terabytes every night. Working closely with the DES collaboration and the Illinois Department of Astronomy, NCSA has developed a system for processing, calibrating, and archiving the wealth of data that will be gathered by the DES. This system will use high-performance computing resources provided by the NSF's XSEDE (Extreme Science and Engineering Discovery Environment) project. NCSA and the University of Illinois have been involved in the DES collaboration since 2005. The data management tools have been tested through periodic Data Challenges, working with simulated data that has progressively become closer and closer in volume and complexity to what will be gathered when DES comes online next year. To learn more about DES, see the story "Dark Energy Project: Moving Forward" in the Spring 2008 issue of NCSA Access Magazine. (Date of Image: March 2008) |

Galaxies Full of Dark Matter
| A view of the universe from NASA's Fermi Gamma-ray Space Telescope. National Science Foundation (NSF)-supported physicists from Brown University studied seven dwarf galaxies, circled in white. Observations indicate those galaxies are full of dark matter because their stars' motion cannot be explained by their mass alone, making them ideal places to search for dark matter annihilation signals.

Ice Sheet Loss at Both Poles Increasing, Major Study Finds
In a landmark study published Thursday in the journal Science, 47 researchers from 26 laboratories report the combined rate of melting for the ice sheets covering Greenland and Antarctica has increased during the last 20 years. Together, these ice sheets are losing more than three times as much ice each year (equivalent to sea level rise of 0.04 inches or 0.95 millimeters) as they were in the 1990s (equivalent to 0.01 inches or 0.27 millimeters). About two-thirds of the loss is coming from Greenland, with the rest from Antarctica.
This rate of ice sheet losses falls within the range reported in 2007 by the Intergovernmental Panel on Climate Change (IPCC). The spread of estimates in the 2007 IPCC report was so broad, however, it was not clear whether Antarctica was growing or shrinking. The new estimates, which are more than twice as accurate because of the inclusion of more satellite data, confirm both Antarctica and Greenland are losing ice. Combined, melting of these ice sheets contributed 0.44 inches (11.1 millimeters) to global sea levels since 1992. This accounts for one-fifth of all sea level rise over the 20-year survey period. The remainder is caused by the thermal expansion of the warming ocean, melting of mountain glaciers and small Arctic ice caps, and groundwater mining.
The study was produced by an international collaboration -- the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) -- that combined observations from 10 satellite missions to develop the first consistent measurement of polar ice sheet changes. The researchers reconciled differences among dozens of earlier ice sheet studies by carefully matching observation periods and survey areas. They also combined measurements collected by different types of satellite sensors, such as ESA's radar missions, NASA's Ice, Cloud and land Elevation Satellite (ICESat) and the NASA/German Aerospace Center's Gravity Recovery and Climate Experiment (GRACE).
"What is unique about this effort is that it brought together the key scientists and all of the different methods to estimate ice loss," said Tom Wagner, NASA's cryosphere program manager in Washington. "It's a major challenge they undertook, involving cutting-edge, difficult research to produce the most rigorous and detailed estimates of ice loss from Greenland and Antarctica to date. The results of this study will be invaluable in informing the IPCC as it completes the writing of its Fifth Assessment Report over the next year."
Professor Andrew Shepherd of the University of Leeds in the United Kingdom coordinated the study, along with research scientist Erik Ivins of NASA's Jet Propulsion Laboratory in Pasadena, Calif. Shepherd said the venture's success is because of the cooperation of the international scientific community and the precision of various satellite sensors from multiple space agencies.
"Without these efforts, we would not be in a position to tell people with confidence how Earth's ice sheets have changed, and to end the uncertainty that has existed for many years," Shepherd said.
The study found variations in the pace of ice sheet change in Antarctica and Greenland.
"Both ice sheets appear to be losing more ice now than 20 years ago, but the pace of ice loss from Greenland is extraordinary, with nearly a five-fold increase since the mid-1990s," Ivins said. "In contrast, the overall loss of ice in Antarctica has remained fairly constant with the data suggesting a 50-percent increase in Antarctic ice loss during the last decade." /NASA

Fredspristagare protesterar mot EU
Den sydafrikanske Nobelpristagaren Desmond Tutu har tillsammans med två andra fredspristagare skrivit till Nobelstiftelsen och protesterat mot Norska Nobelkommitténs beslut att ge fredspriset till EU. I ett öppet brev skriver de att EU inte främjar fred på det sätt som Alfred Nobel åsyftade i sitt testamentet, rapporterar AFP/SvD

Känns riktigt. Om ingen protesterar till Nobelstiftelsen finns öppenbarlig risk att den norska Nobelkommittén postumt ger priset till Schutzstaffel (SS) eller kanske sannolikare, till Sarah Palin.
