"The problem with this energy-rich plasma is figuring out how to contain it, since it exists at extremely high temperatures (up to 150 million degrees Celsius, or 10 times the temperature at the Sun’s core). Any material you can find on Earth isn’t going to make a very good jar."

To give you an idea of how difficult this is, earlier this year, the German nuclear fusion machine managed to heat hydrogen gas to 80 million degrees Celsius, and sustain a cloud of hydrogen plasma for a quarter of a second. It might seem like a blip, but it was hailed as a massive milestone.

China’s facility has since claimed to have beaten that, announcing back in February that it produced hydrogen plasma at 49.999 million degrees Celsius, and held onto it for 102 seconds.

So far, neither machine has been able to prove that it could produce a sustained amount of energy through nuclear fusion, just that it could get the materials hot enough to begin the process.

But now physicists at the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) think they have a better way.

The numbers in the science of fusion just blows my mind every time I read about it. 80 million degrees Celsius. Mental.

0 |

the numbers in $$ that they've pumped into it so far is equally mental... i mean, Jesus its almost unlimited funds, the top minds from each field and the holy grail of both a Nobel Prize and Savior of Humanity as the accolades and they've only managed to heat the plasma for a few moments.. i mean c'mon fer fucks sakes lads get your finger out

Have they investigated incorporating a goodfellas pizza into the mix? Burnt the skin on the roof of my mouth off a few times taking a bite of one straight out of the oven.

All I ask in return for this is a share of the Nobel Prize.

lol I'd say I burn the bake aff myself every 1 in 3 pizzas I eat. No patience at all when it comes to a fine pizza. Just like RJs patience when it comes to fusion.

The Price of Solar Is Declining to Unprecedented Lows

Despite already low costs, the installed price of solar fell by 5 to 12 percent in 2015

Going forward, the declining price of solar across all categories demonstrated by the latest Lawrence Berkeley National Laboratory reports coupled with the extension of the federal renewable energy investment tax credit through 2019 should drive a continued expansion of the U.S. solar market and even more favorable economics in the next few years. It will certainly be interesting to see what kind of market dynamic develops as solar approaches the tipping point where it becomes more economical than conventional forms of electricity generation.

How exactly did lightning kill 323 reindeer in Norway?

Lightning during a recent thunderstorm in Norway killed a herd of 323 reindeer — 70 of them calves — making it one of the deadliest strikes ever. Hunters in a remote area discovered the bodies last Friday, according to the Norwegian News Agency.

We usually hear about lightning striking people, but it does kill animals, too. Two scientists at an Australian research institute have found that everything from seal pups to wild turkeys to elephants and giraffes can be killed by lightning.

Was this a freak accident, or is it common? And how does this happen? I spoke to John Jensenius, a lightning safety expert from the National Oceanic and Atmospheric Administration, to learn about the science behind these deadly herd strikes.

A first for direct-drive fusion

Scientists at the University of Rochester have taken a significant step forward in laser fusion research.

Experiments using the OMEGA laser at the University's Laboratory of Laser Energetics (LLE) have created the conditions capable of producing a fusion yield that's five times higher than the current record laser-fusion energy yield, as long as the relative conditions produced at LLE are reproduced and scaled up at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California.

"We have compressed thermonuclear fuel to about half the pressure required to ignite it. This is the result of a team effort involving many LLE scientists and engineers," said Regan, the leader of the LLE experimental group.

If ignited, thermonuclear fuel would unleash copious amounts of fusion energy, much greater than the input energy to the fuel.

"In laser fusion, an ignited target is like a miniature star of about a 10th of a millimeter, which produces the energy equivalent of a few gallons of gasoline over a fraction of a billionth of a second. We are not there yet, but we are making progress" said Betti, the Robert L. McCrory Professor at the Laboratory for Laser Energetics.

Glimpses of the Madala boson: have we detected the dark Higgs?

Has lightning struck twice at the Large Hadron Collider? Using the same data used to discover the Higgs boson in 2012, physicists from South Africa, India and Sweden claimed to see evidence of its dark matter counterpart – a new particle the team dubbed the Madala boson.

If true, this could be groundbreaking – the long-sought-after connection between particle physics and dark matter, the mysterious ‘stuff’ that makes up around 85% of matter in the universe.

But as yet, the theory represents the views of only one research group. A draft paper on the work uploaded to the arXiv in November has, to date, received no citations by other physicists, nor has it been subjected peer-review.

It seems a revelation almost as mysterious as its subject matter.

Biohybrid robot 'crawls' using muscles taken from a slug's mouth

By combining tissues from a slug with flexible 3D-printed parts, researchers have created a 'biohybrid' that crawls like a sea turtle on the beach – albeit extremely slowly.

A muscle from the slug's mouth helps the robot move, which is currently controlled by an external electrical field. Future iterations of the device will include ganglia – bundles of neurons and nerves that normally conduct signals to the muscle as the slug feeds – as an organic controller.

How Do Photons Experience Time?

Traveling at the speed of light, photons emitted by the Sun take a little over eight minutes to reach the Earth. The 93 million mile (150 million km) journey across the expanse of empty space is no obstacle to this light, but it means that when we look at the Sun, we’re seeing it as it was a short time in the past, not as it is instantaneously from our perspective. If the Sun were to wink out of existence right now, we wouldn’t know it — not from its light, not from its gravity — until eight minutes later. But what about from the photon’s point-of-view? We know that if you travel close to the speed of light, Einstein’s theory of special relativity kicks in, and time dilates while lengths contract. Photons, however, don’t move close to the speed of light but rather at it. So how much has a photon emitted by the Sun aged by time it reaches the Earth?

CRISPR. Sum pup.

Scientists Successfully Genetically Modify Human Embryos Against HIV

Last year, researchers in China shocked the world (and alarmed many in the scientific community) by modifying the DNA of human embryos. Now, as reported in Nature News, a research team led by Yong Fan at Guangzhou Medical University has used CRISPR, a powerful gene editing tool, to introduce HIV-resistance into the embryos.

This work could greatly aid humanity, helping us better understand how to combat a host of diseases and medical conditions. Of course, such advances will take time (especially given how some fear genetic engineering). But ultimately, the work is equal parts remarkable and promising.

Scientists Accidentally Discover Efficient Process to Turn CO2 Into Ethanol

Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change. Their findings were published in the journal ChemistrySelect.

The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, when they realized the first step in their process managed to do it all by itself. The reaction turns CO2 into ethanol, which could in turn be used to power generators and vehicles.

Five Independent Signs Of New Physics In The Universe

Since the Large Hadron Collider at CERN turned on, it’s brought with it an incredible slew of results. Large numbers of rare, exotic and unstable particles have been created, and their decays have been measured to unprecedented precision. The Higgs boson has been created and observed to have a mass of 126 GeV/c2, branching and decaying in exactly the ratios the Standard Model predicts. As it now stands, we’ve detected every particle and antiparticle predicted by the most successful particle physics theory of all time. Unless we get hit by a big physics surprise, the LHC will become renowned for having found the Higgs Boson and nothing else fundamental. If these results hold, there’s no window into what lies beyond the Standard Model coming from traditional experimental particle physics.

But that by no means is the same thing as saying “the Standard Model is all there is.” Quite to the contrary, there are a large number of observations that tell us quite clearly that there’s very likely more to the Universe than just the quarks, leptons and bosons of the Standard Model. While experiments are telling us that low-energy supersymmetry and extra dimensions probably don’t exist (or are so constrained that they’re irrelevant), there are plenty of pieces of evidence that there’s more to existence than the Standard Model alone. What else is out there? There are five strong, independent lines of inquiry that reveal there’s got to be something.

Massive 'lake' discovered under volcano that could unlock why and how volcanoes erupt

Scientists from the University of Bristol and partner universities in Germany, France, Canada and Wales, have discovered a huge magmatic lake, 15 kilometres below a dormant volcano in Bolivia, South America.

The body of water - which is dissolved into partially molten rock at a temperature of almost 1,000 degrees Celsius - is the equivalent to what is found in some of the world's giant freshwater lakes, such as Lake Superior.

The find has now led scientists to consider if similar bodies of water may be 'hiding' under other volcanoes and could help explain why and how volcanoes erupt.

Harvard scientists think they've pinpointed the physical source of consciousness

"Scientists have struggled for millennia to understand human consciousness - the awareness of one's existence. Despite advances in neuroscience, we still don't really know where it comes from, and how it arises.

But researchers think they might have finally figured out its physical origins, after pinpointing a network of three specific regions in the brain that appear to be crucial to consciousness."
