Packed with novel devices and science instruments, Proba-2 is demonstrating technologies for future ESA missions while providing new views of our Sun.
At a press conference on Tuesday at the Royal Observatory of Belgium in Brussels, the team behind the small satellite declared themselves extremely happy with its first three months in orbit and unveiled Proba-2's first solar observations.
The stellar-mass black holes [1] found in the Milky Way weigh up to ten times the mass of the Sun and are certainly not be taken lightly, but, outside our own galaxy, they may just be minor-league players, since astronomers have found another black hole with a mass over fifteen times the mass of the Sun. This is one of only three such objects found so far.
An innovative computational technique that draws on statistics, imaging and other disciplines has the capability to detect errors in sensitive technological systems ranging from satellites to weather instruments.
The patented technique, known as the Intelligent Outlier Detection Algorithm, or IODA, is described this month in the Journal of Atmospheric and Oceanic Technology.
In an advance that might interest Q-Branch, the gadget makers for James Bond, the National Institute of Standards and Technology (NIST) and partners from industry and academia have designed and tested experimental antennas that are highly efficient and yet a fraction of the size of standard antenna systems with comparable properties. The novel antennas may be useful in ever-shrinking and proliferating wireless systems such as emergency communications devices, micro-sensors and portable ground-penetrating radars to search for tunnels, caverns and other geophysical features.
NEW BRUNSWICK, N.J. – While re-entry and skill-building programs offered by the New Jersey Department of Corrections (NJDOC) at its 11 prisons are heavily used and generally viewed favorably by inmates, many anticipate a difficult return to society due to their underlying health conditions and concerns about finances and support systems.

By comparing the immune responses of both, young and old mice, to bacterial infection they found that the number of macrophages, one of the major cell populations involved in the elimination of infecting bacteria, decreases rapidly in aged mice. This decline in the number of fighters and the associated weakness of the immune defense may be responsible for the age-associated increase in susceptibility to infections. The HZI researchers have succeeded to enhance the resistance to an infection in aged mice by treating them with a macrophage-specific growth factor.

Research from Malawi, Birmingham and Liverpool has renewed hope that an effective vaccine could be developed against nontyphoidal strains of Salmonella. The work, funded by the Wellcome Trust and GlaxoSmithKline, suggests that the body's immune system could be primed to tackle even the most resilient of strains.
Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states, according to research by scientists at the Southwest Research Institute appearing online in Nature Geoscience Jan. 24, 2010.
People may need 3-D glasses to see life-like images, but rainfall and cloud data from the Tropical Rainfall Measuring Mission or TRMM satellite gives scientists a three-dimensional look at tropical cyclones without the glasses.
TRMM passed over tropical cyclone Magda on January 21 at 1927 UTC (2:27 p.m. ET) when it was off Western Australia's northern coast and soon to make landfall TRMM captured a look at its rainfall and cloud heights. That data was used to create a 3-D image of how high Magda's clouds were, and how heavily the rain was falling within the storm.
When Cyclone Magda made landfall from Collier Bay at around 5 a.m. local time on January 22 in northern Australia, NASA's Terra satellite captured an image of the storm. Magda is now dissipating rapidly over land in northern West Australia.
Michigan State University astronomer Megan Donahue uses words such as "cool" and "interesting" to describe the two distinct "tails" found on a long tail of gas that is believed to be forming stars where few stars have been formed before.
Donahue was part of an international team of astronomers that viewed the gas tail with a very long, new observation made by the Chandra X-ray Observatory and detailed it in a paper published this month in the publication Astrophysical Journal.
Civil engineers at the University of Washington and the U.S. Army Corps of Engineers' Seattle office have taken a first look at how dams in the Columbia River basin, the nation's largest hydropower system, could be managed for a different climate.
An area of low pressure in the Southern Indian Ocean, located close to Australia's northwestern coast was being watched for development yesterday. This morning it exploded into Tropical Storm Madga. NASA's Tropical Rainfall Measuring Mission, or TRMM satellite noticed that Magda's outer rainbands were already affecting land today..
