Four radioactive "babies" get their names

We all know that naming a new baby is never easy; everyone has their opinion and arguments often arise when deciding on a suitable moniker. In a similar way, the naming of new elements on the periodic table is subject to a lot of discussion and comment involving a vast range of constraints, and a committee solely dedicated to the process. Despite the difficulty and length of the process, four new elements recently added to the periodic table now have proper names that honor the places and people essential to their discovery.Read More


Brain-like supercomputing platform to explore new frontiers

In the old days, it was common to hear a computer chip referred to as an "electronic brain." Modern chip designs are now making such labels even more apt. Lawrence Livermore National Laboratory (LLNL) is set to take receipt of a brain-inspired supercomputing platform developed by IBM Research. The first-of-a-kind system is based on a neurosynaptic computer chip known as IBM TrueNorth, and can process the equivalent of 16 million neurons and 4 billion synapses while consuming just 2.5 watts of power.Read More


Four new elements confirmed

Chemistry textbooks are in need of a rewrite with the addition of four new elements to the Periodic Table. The International Union of Pure and Applied Chemistry (IUPAC) has confirmed the existence of four new elements with the atomic numbers 113, 115, 117, and 118, which were discovered by laboratories in Japan, the United States, and Russia. This bumper group of new elements completes the 7th row of the Periodic Table and clears the way for the discoverers to start thinking up names for them.Read More


New fluorescent lighting phosphors slash use of rare-earth elements

Phosphors are essential to fluorescent lighting, and thus office parks the world over, but their use of rare-earth elements makes them less than ideal. To address that issue, new types of phosphors have been developed that use substantially less rare-earth elements than current phosphors found in fluorescent bulbs. This could reduce the reliance on the limited supplies of rare-earth elements until fluorescent lighting can be completely replaced by LED lighting, which isn't expected to occur for over a decade.Read More


World’s most powerful laser diode arrays deployed

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

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.Read More


Nuclear weapons write their own security codes

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.Read More

DARPA wants to develop electronic memory-restoring implants

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
