Submission + - SPAM: Physicists Examine The Viability Of Spherical Tokamaks In Producing Energy

mdsolar writes: Nuclear fusion has been powering our sun for the past 4.5 billion years. Unlike fission — the process that powers our current nuclear facilities — fusion generates energy by fusing the nuclei of lighter atoms into heavier ones, and produces no long-term radioactive waste.

Imagine if we manage to replicate and miniaturize the process taking place in the core of stars. This would not only provide us a low-cost, clean and virtually limitless source of energy, it would also end our unsustainable reliance on polluting fossil fuels.

In a recent paper published in the journal Nuclear Fusion, a team of physicists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has detailed the design of a viable and efficient fusion device — one that already exists in an experimental form.

The spherical device, known as a “tokamak,” can contain high-energy, superheated plasma produced through nuclear fusion using relatively low and inexpensive magnetic fields. This, the researchers believe, makes it a leading candidate to complement the International Thermonuclear Experimental Reactor — a doughnut-shaped tokamak that 35 nations are building in France to demonstrate the feasibility of fusion power.

The PPPL tokamaks spherical, “cored apple” design also allows tritium — a rare hydrogen isotope — to be created,

An anonymous reader writes: The BBC has an interesting story about how a famous 1950s jet is being repurposed for use in 2018. From TFA: "The F-104s will fly over the Atlantic Ocean, their pilots taking the jets to around 60,000ft, the jets climbing at an acute angle to give the rockets the right trajectory to leave the pull of the Earth’s gravity." A good read for fans of space and aeronautics.

Submission + - Mediterranean diet better for the heart than taking statins, major study suggest (

An anonymous reader writes: A Mediterranean diet could be better than statins at reducing the risk of an early death for millions of Britons, research suggests.

Leading heart experts said patients should be prescribed the diet — rich in fruit, vegetables, fish, nuts, whole grains and olive oil — before being put on drugs.

In the first major study to look at the impact of the Med diet on survival of heart patients, experts found it cut the chances of early death by 37 per cent.

Previous research has found just taking statins cuts mortality by 18 per cent. Experts said the figures were not directly comparable, and that many heart patients could get maximum benefit by doing both.

The facility will contain seven supercomputers, to host the seven teams entered in the cyber battle, which takes place on 4 Augus at Def Con in Las Vegas.

Submission + - SPAM: First image released from MeerKAT radio telescope

schwit1 writes: Even operating at a quarter of its eventual capacity, South Africa's MeerKAT radio telescope showed off its phenomenal power Saturday, revealing 1,300 galaxies in a tiny corner of the universe where only 70 were known before.

The image released Saturday was the first from MeerKAT, where 16 dishes were formally commissioned the same day.

MeerKAT's full contingent of 64 receptors will be integrated next year into a multi-nation Square Kilometer Array (SKA) which is is set to become the world's most powerful radio telescope.

An anonymous reader writes: Veertu is the very first native OS-X hypervisor available on the AppStore. Veertu uses new hypervisor framework introduced in Yosemite and therefore doesn't need installing any kext kernel modules like other hypervisors. It's also very fast and lightweight and could become an interesting alternative to Parallels or VMware Fusion. It's available on the AppStore for free and can run Linux images from the online library. Running other images such as Windows will cost $39.99

astroengine writes: SpaceShipTwo co-pilot Michael Alsbury was not properly trained to realize the consequences of unlocking the vehicle’s hinged tail section too soon, a mistake that led to his death and the destruction of the ship during a test flight in California last year. Responsibility for the accident falls to SpaceShipTwo manufacturer Scaled Composites, a Mojave, Calif., company owned by Northrop Grumman Corp, the National Transportation Safety Board (NTSB) determined at a webcast hearing on Tuesday. Poor oversight by the Federal Aviation Administration (FAA), which oversees commercial spaceflights in the United States, was also a factor in the accident, the NTSB said.

Submission + - Two Years Later, White House Responds To 'Pardon Edward Snowden' Petition (

An anonymous reader writes: In June of 2013, a petition was posted to demanding that Edward Snowden receive a full pardon for his leaks about the NSA and U.S. surveillance practices. The petition swiftly passed 100,000 signatures — the point at which the White House said it would respond to such petitions. For two years, the administration was silent, but now they've finally responded. In short: No, Edward Snowden won't be receiving a pardon. Lisa Monaco, the President's Advisor on Homeland Security and Counterterrorism, said, "Mr. Snowden's dangerous decision to steal and disclose classified information had severe consequences for the security of our country and the people who work day in and day out to protect it. If he felt his actions were consistent with civil disobedience, then he should do what those who have taken issue with their own government do: Challenge it, speak out, engage in a constructive act of protest, and — importantly — accept the consequences of his actions. He should come home to the United States, and be judged by a jury of his peers — not hide behind the cover of an authoritarian regime. Right now, he's running away from the consequences of his actions."

Submission + - Samsung launches Galaxy A8 The Slimmest Phone ever (

mymobotips writes: Samsung has silently launched its slimmest smartphone ever in China after the predecessors A5 and A6. The slimmest of all, Galaxy A8 is not a features-storehouse, but it displays the designing achievement for this techie-genie Samsung.Co. popular for getting criticism for designs.

Galaxy A8 Specification

The smartphone possessing a metallic body is only 5.9mm thick, weighing just151 grams (5.3 oz) sports a bezel size. It highlights a 5.7-inch full HD(1080x1920p) Super AMOLED display,which is the largest in this variation.
This smartphone is powered by a 1.5GHz 64-bit Qualcomm Snapdragon octa-core processor and 2GB RAM. It is having 16 and 32GB memory-storage options. The phone also offers a microSD card slot for memory-expansion.
It is featuring a 16MP ISO CELL rear camera along with 5MP front-facing camera like the Galaxy S6. The phone is loaded with a 3050mAh battery and is running on Android 5.1 Lollipop with Samsung's TouchWiz UI. This Galaxy A8 would also sport a fingerprint scanner combined with the phone's Home button.
Samsung has inculcated all the new technologies like a fingerprint sensor and hand-wave detection activating a photo timer. It is an obvious bet in the Asian market wherein the userbase looks all these characteristics in a mid-range phone (like the HTC Desire 826) and it is difficult to comment whether the customers would buy the Galaxy A8 just for its premium metal body and some extra features with a expensive cost. According to rumors the phone would cost about 3,499 yuan (about $560).
Till now the phone is not available in the US or European market but would be soon. If the model is not available then, the features might be seen in the upcoming Galaxy Note 5.
