Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae – colorful, glowing clouds of dust and gas. In recent decades these nebulae, once thought to be mostly spherical, have been observed to often emit powerful, bipolar jets of gas and dust.
Four unknown galaxy clusters each potentially containing thousands of individual galaxies have been discovered some 10 billion light years from Earth. An international team of astronomers, led by Imperial College London, used a new way of combining data from the two European Space Agency satellites....
When Ray Breslin and Emil Rottmayer attempted a highly daring escape from a super-high security prison in this fall’s thriller Escape Plan, audiences got up close to see (spoiler alert!) our two heroes — played by Sylvester Stallone and Arnold Schwarzenegger, respectively — engage in a gunfight with the prison’s “crew”....
Your employer probably isn’t tracking your every move just yet, but with new technology from Hitachi, it might not be that far down the road. Obviously there are ways for employers to track your productivity now whether it’s cameras or looking at your internet logs, but it’s really time consuming and not very informative for most employees.

The decision announced Monday clears the way for Google's Planetary Ventures LLC to take over management of the 1,000-acre Moffett Federal Airfield....
A team led by astronomers at The Australian National University has discovered the oldest known star in the Universe, which formed shortly after the Big Bang 13.7 billion years ago. The discovery has allowed astronomers for the first time to study the chemistry of the first stars, giving scientists a clearer idea of what the Universe was like in its infancy.
Scientists have solved a major problem with the current standard model of cosmology identified by combining results from the Planck spacecraft and measurements of gravitational lensing in order to deduce the mass of ghostly sub-atomic particles called neutrinos.
AUVSI's Unmanned Systems 2014 features the largest exhibit hall dedicated to unmanned systems in the world with over 350,000 sq. ft. (32,500 sq. m.) of space and more than 600 exhibitors. It is the place to find the latest solutions and products the industry has to offer and to connect with colleagues and new business partners.
Announced today by Acopian Power Supplies (Easton, PA) is the UL recognition and CE approval of their mini encapsulated series of linear regulated power supplies.

So what's the best way to protect them? Here's a great opportunity to showcase your opinion and knowledge on the topic by answering the question below. Ready to give it a try?
Gowanda Electronics (Gowanda, NY) announced that the company recently achieved military approval for four thru-hole RF inductor series: MLRF10M, MLRF15M, MLRF18M and MLRF17S. These Gowanda series meet the military’s Qualified Product List (QPL) requirement for military spec MIL-PRF-15305.
TTTech announced the availability of the first AFDX switch hardware with the standard ANSI form factor 3U VPX (formerly known as VITA 46). The rugged, light, and space-saving switch will support customers in the design of optimized aerospace system architectures.
Using very precise ground-based observations, Stephen Lowry (University of Kent, UK) and colleagues have measured the speed at which the near-Earth asteroid (25143) Itokawa spins and how that spin rate is changing over time. They have combined these delicate observations with new theoretical work....
Mill-Max Mfg. Corp. (Oyster Bay, NY) announces the addition of new crimp pins to their selection of wire termination products. These new pins are commercial-off-the-shelf (COTS) equivalents to the popular Mil-Spec M39029 crimp pins.
UTC Aerospace Systems (CHARLOTTE, N.C.) introduces the newest high definition (HD) camera in its Sensors Unlimited MiniSWIR product line: the GA1280JSX. This new addition is a compact, mil-rugged 0.9MP high-resolution, high-sensitivity, shortwave infrared (SWIR) video camera....
Flying in a fighter jet isn’t an experience most of us will ever have. Personally, I’ve never had the urge, but for some, not being able to soar like Maverick is heartbreaking. Luckily for any wannabe pilots, Metropolis Entertainment — who make footage for simulators for places like this one which will show at London’s Science Museum — are more than willing to share the wealth.
Sadly, human history offers all too many examples of how chemical weapons can be used to devastating effect. The employment of chemical warfare agents (CWAs) dates back to at least as far as 1000 BC, when the Chinese used arsenical smokes as weapons.
Here’s an oldie but goodie. Last year, Four Corners — an Australian current affairs program — did an expose on the troubled F-35 Joint Strike Fighter program, and their conclusions were ... none-too complimentary. Like their American counterparts, Australia is pursuing a one-size-fits all solution....
Linear Technology (Milpitas, CA) announces the LTC3638, a 140V input-capable high efficiency buck converter that delivers up to 250mA of continuous output current. It operates from an input voltage range of 4V to 140V, making it ideal for telecom, industrial, avionic and automotive applications.
RFMW, Ltd. (San Jose, CA) announces design and sales support for a pair of high power GaN SPDT switches from TriQuint.
