LHC proton-lead collisions may have created new form of matter

In September, the Large Hadron Collider (LHC) was being tuned to enable it to study proton-lead nucleus collisions for a data run next year. Eventually it ran and data was collected on the collisions for a period of four hours. When the data was analyzed, it revealed that some particle pairs produced in the collision were traveling in the same direction – a highly unusual situation. Although the data is not sufficient for certainty, the consensus appears to favor this as evidence for production of a color-glass condensate, a new form of exotic matter that has so far only existed as a theory.

Superfast laser delivers record-breaking peak power of one petawatt

Not even a month since researchers at the Lawrence Livermore National Laboratory's National Ignition Facility (NIF) announced a 500 trillion watt laser shot, researchers at the Berkeley Lab Laser Accelerator (BELLA) have managed to deliver a record-breaking petawatt, that is, a quadrillion watts, in a pulse just 40 femtoseconds long at a rate of one pulse every second. To put that in perspective, a petawatt is more than the combined output of all electric power plants in the world at any given time and one femtosecond is a quadrillionth of a second. Read More

U.S. Army weapon shoots lightning bolts down laser beams

Thought that title might get your attention, but shooting lightning bolts down laser beams is just what a device being developed at the Picatinny Arsenal military research facility in New Jersey is designed to do. Known as a Laser-Induced Plasma Channel, or LIPC, the device would fry targets that conduct electricity better that the air or ground that surrounds them by steering lightning bolts down a plasma pathway created by laser beams.Read More

Battery-powered plasma flashlight makes short work of bacteria

An international team of scientists has created a handheld, battery powered device that has been shown to effectively rid skin of bacteria in an instant by blasting it with plasma. The plasma flashlight, which shouldn’t be confused with a plasma torch that will damage much more than bacteria if used on the skin, could provide a convenient way for paramedics and military personnel to deal with harmful bacteria in the field.Read More

Cold plasma used to kill bacteria on raw chicken

Judging by the number of folks who fall prey to food-borne illness each year, food safety is serious business, especially when you consider that pathogens such as Campylobacter and Salmonella contaminate over 70 percent of the raw chicken meat tested. Now, recent research from a food safety team at Pennsylvania's Drexel University offers proof-of-concept for what may one day be a common approach to preventing food-borne illness from raw poultry and meat products - the use of high-energy, low temperature plasma to eliminate unwanted bacteria while leaving the food basically unchanged.Read More

World's most powerful X-ray laser recreates conditions at the center of a star

To say things are really heating up at the US Department of Energy's SLAC National Accelerator Laboratory isn't just a bad pun, it's one hell (sorry) of an understatement. An Oxford-led team used the Stanford-based facility that houses the world's most powerful X-ray laser to create and probe a 2-million-degree Celsius (or about 3.6 million degrees Fahrenheit) piece of matter. The experiment allowed the scientists the closest look yet at what conditions might be like in the heart of the Sun, other stars and planets.Read More

New plasma "brush" may mean painless cavity filling

We've been keeping an eye on efforts to make the dreaded dentist's drill a thing of the past for some time, and now there's more good news on the horizon for the cavity-prone (and pain-phobic). Engineers at the University of Missouri (MU) in conjunction with Nanova, Inc. have successfully lab-tested a plasma "brush" that can painlessly clean and prep cavities so well, there's no need for mechanical abrasion prior to filling. The really good news is that human clinical trials begin soon and, if all goes well, the device could hit dentist's offices as soon as late 2013.Read More

Burton rolls out True 3D laser plasma display

Engineers from Burton Inc. in Japan have rolled out a "True 3D" display, which evolved from work begun five years previously by teams at Keio University and Japan's national institute of Advanced Industrial Science and Technology (AIST). While most 3D displays available today involve a form of optical illusion that depends on the parallax or disparity inherent in human binocular vision, this new system, which can function in air or under water, needs no screen of any sort, and the effect is quite impressive.Read More

Plasma-filled bags could replace the Petri dish

The humble Petri dish may soon be a thing of the past. A team of researchers in Germany have developed a new technique for treating plastic bags with plasmas to turn them into sealed, sterile containers suitable for microbiology work with much less chance of contamination than traditional containers. This holds the promise of not only decreasing the possibility of contamination in stem cell and live-cell therapy techniques, but also the potential for cultivating whole human organs for transplant surgery.Read More

Steampunk Plasma Speaker produces electrifying sound

So, you've downloaded some songs by Abney Park (one of the world's few steampunk bands) onto your Datamancer laptop or your Old Time Computers-accessorized PC ... do you just listen to them through the built-in speakers? Not if you're Polish tinkerer Conscious Flesh. He has created a speaker that not only looks delightfully mad-Victorian-scientist-esque, but it actually produces sound using plasma discharges. Nikola Tesla would definitely approve.Read More
