Smaller, cheaper neutron sources and new opportunities for simulating the extreme conditions at the center of stars are among the possible benefits of new research carried out by physicists in the US and Germany. The group directed rapid-fire pulses of intense blue light from a compact laser at arrays of nanostructures to generate a dense plasma yielding large numbers of neutrons created by nuclear fusion.

Scientists have built ever more energetic lasers in the quest to demonstrate nuclear fusion’s feasibility as an energy source. The National Ignition Facility (NIF) in California, for example, generates pulses with a whopping 1.8 MJ of energy, in order to compress tiny pellets of deuterium and tritium to the point where the nuclei fuse and emit copious numbers of neutrons. The aim is to achieve ignition, when the alpha particle released by the fusing nuclei provides the heat for a self-sustaining reaction – with the energy of the emitted neutrons ultimately being tapped to produce electricity. However, NIF is enormous – occupying the area of three football pitches – and, like other high-energy lasers, can only fire a handful of times a day.

Some researchers are instead working on less energetic but more rapid-fire lasers. These will never get anywhere close to ignition, but can still achieve exceptionally high intensities – thanks to the extreme brevity and hence power of their pulses. Such lasers can create plasmas with very high energy densities ideal for studying extreme astrophysical environments, for example. These devices could also potentially be used as compact sources of neutrons, which probe atomic structure in ways not possible with X-rays. Neutrons are usually produced at large accelerators or reactors and a compact source would be welcomed by scientists.

Been Debating If I Should Finish This Story

Posted by Jacqueline Loggins on April 23, 2018 at 5:16pm 0 Comments

Effortlessly I pulled the tan stocking above my knee, sliding it across the thickness of my thigh before securing it to the garter. My hand now moved to my large, plump lips, where I dotted a speck of moisturizer before rubbing them together to get a perfect, even distribution. They now taste and smelled of cherry spice. Now for some color, I thought, opening the pallet of endless lip stains to see which would suit my attire for the evening.

This one! I decided as my finger tapped near the burnt orange circle titled Pale Sunbeam. The laser brush slid across airbrushing my top lip, then the lower. Blotting my lips, I smiled in the light-framed mirror, satisfied with my choice of color. The spotlights illuminated my sequin bra top, creating dazzling sparkles of purple and gold.…

I Was Starving

Posted by Jacqueline Loggins on April 23, 2018 at 4:55pm 0 Comments

No, I wasn't starving for food. I was starving or opportunity, direction, human interaction and friendship, but mostly I was starving for innovation and success. You see, around this time last year I found myself in a rut. I was doing hair, writing stories, making dolls etc etc. It felt like being on a hamster wheel to nowhere. And top on of everything else, our family was in a financial bind. Yes, I our ends didn't meet and we have more month at the end of our money.

One day while trying to complete a doll and at the same time worried if our gas would be cut off, something just told me to stop. I was trying to put out so much, but was taking nothing back in in return. Yes, I had burned out and what's worse our family was broke. So, I suggested to my…

SKYCITY TALKRADIO

THE UNDERGROUND BY ROXANNE BLAND

Life as alpha of a werewolf pack is anything but predictable. But even Parker Berenson is surprised by the latest twist: he’s fallen in love with a space alien. Problem is, he suspects Melera, his sexy new flame, might be the serial killer terrorizing Seattle. Or maybe she isn’t. After all, just because she’s an interstellar assassin doesn’t mean she’s guilty.
