World’s most powerful laser diode arrays deployed

By - March 15, 2015 2 Pictures
The High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) under construction in the Czech Republic is designed to generate a peak power of more than 1 quadrillion watts (1 petawatt, 1015 watts). The key component to this instrument – the laser "pump" – will be a set of solid-state laser diode arrays recently constructed by Lawrence Livermore National Laboratory (LLNL). At peak power, this electronic assemblage develops a staggering 3.2 million watts of power and are the most powerful laser diode arrays ever built. Read More

DNAtrax tracks tainted food with molecular bar code

By - January 11, 2015 3 Pictures
According to the US Center for Disease Control (CDC), 129,000 Americans are sent to hospital and 3,000 die each year from food poisoning. Currently, tracing contaminated food is largely a matter of record keeping and detective work, but Lawrence Livermore National Laboratory (LLNL) researchers, in partnership with DNATrek, have developed DNATrax, a DNA-based additive for directly tracking food from producer to consumer.

Nuclear weapons write their own security codes

By - November 24, 2014 1 Picture
Nuclear weapons are a paradox. No one in their right mind wants to use one, but if they're to act as a deterrent, they need to be accessible. The trick is to make sure that access is only available to those with the proper authority. To prevent a real life General Jack D Ripper from starting World War III, Livermore National Laboratory’s (LLNL) Defense Technologies Division is developing a system that uses a nuclear weapon's own radiation to protect itself from tampering.

DARPA wants to develop electronic memory-restoring implants

By - July 9, 2014 1 Picture
Earlier this year, we heard about how DARPA (the Defense Advanced Research Projects Agency) was setting up its new Biological Technologies Office. The goal of that division is to "merge biology, engineering, and computer science to harness the power of natural systems for national security." This week, the agency released details of one of the office's key projects, called Restoring Active Memory. It's aimed at using implantable "neuroprosthetics" to help army veterans and other people recover from memory deficits caused by brain injury or disease. Read More

New materials developed that are as light as aerogel, yet 10,000 times stronger

By - June 22, 2014 5 Pictures
Imagine materials strong enough to use in building airplanes or motor cars, yet are literally lighter than air. Soon, that may not be so hard to do because a team of researchers from MIT and Lawrence Livermore National Laboratory (LLNL) have developed new ultra-lightweight materials that are as light as aerogel, but 10,000 times stiffer, and may one day revolutionize aerospace and automotive designs.

LLNL improving the efficiency of 3D metal printing

By - June 18, 2014 2 Pictures
To paraphrase Samuel Johnson, there was a time when 3D metal printing was like a dog walking on his hind legs – it wasn't done well; but you were surprised to find it done at all. Now that laser sintering or Selective Laser Melting (SLM) is used for everything from printing rocket engine components to semi-automatic pistols, the time for surprise may b long past, but the technology still has plenty of room for improvement. That's why researchers at the Lawrence Livermore National Laboratory (LLNL) are working on simulations to improve the speed of 3D laser printing and the quality of the final product by using higher-powered lasers.

Scientists announce breakthrough in quest for fusion power

By - February 13, 2014 2 Pictures
In a perfect example of beating swords into plowshares, a team of scientists at the Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF) in California reached a milestone in the quest for practical fusion power using a process designed for the development and testing of nuclear weapons. The announcement in the February 12 issue of Nature claims that the team used the world’s most powerful laser barrage to produce a controlled fusion reaction where more energy was extracted from the fuel than was put into it.

Gemini Planet Imager snaps first direct image of exoplanet Beta Pictoris b

By - January 9, 2014 7 Pictures
Following almost 10 years of development, the Gemini Observatory has debuted an advanced planet imaging instrument and captured a direct image of exoplanet Beta Pictoris b, signifying a breakthrough in our ability to analyze extrasolar planets. Called the Gemini Planet Imager (GPI), the tool uses an advanced optics system with an infrared spectograph to retrieve direct images of young planets orbiting distant stars. Read More

DARPA's new 1.8-gigapixel camera is a super high-resolution eye in the sky

By - February 11, 2013 8 Pictures
DARPA recently revealed information on its ARGUS-IS (Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System), a surveillance camera that uses hundreds of smartphone image sensors to record a 1.8 gigapixel image. Designed for use in an unmanned drone (probably an MQ-1 Predator), from an altitude of 20,000 ft (6,100 m) ARGUS can keep a real-time video eye on an area 4.5 miles (7.2 km) across down to a resolution of about six inches (15 cm).
