Submission + - Hobbyist gives iPhone 7 the headphone jack we've always wanted (engadget.com)

intellitech writes: From the article: "For those of you who miss the iPhone headphone jack, you're definitely not alone. But Strange Parts creator Scotty Allen missed it so much that he decided to add one to his iPhone 7. He just posted a video of the project's entire saga, with all of its many ups and downs, and in the end he holds what he set out to create — a current generation iPhone with a fully functional headphone jack. It turns out, real courage is adding the headphone jack back to the iPhone."

Submission + - SpaceX Releases Animation of Planned Falcon Heavy Launch (gizmodo.com.au)

intellitech writes: SpaceX CEO Elon Musk recently shared a new (and, really freaking cool) animation demonstrating how the company plans to launch the maiden flight of their Falcon Heavy system later this year, which will be the most powerful rocket since the Saturn V used for the moon landings during the Apollo-era.

According to Elon Musk's Instragram post, "FH is twice the thrust of the next largest rocket currently flying and ~2/3 thrust of the Saturn V moon rocket." He also reiterates that a "lot that can go wrong in the November launch."

Submission + - Predatory Journals Hit By "Star Wars" Sting (discovermagazine.com)

intellitech writes: From the article:

Inspired by previous publishing “stings”, I wanted to test whether ‘predatory‘ journals would publish an obviously absurd paper. So I created a spoof manuscript about “midi-chlorians” – the fictional entities which live inside cells and give Jedi their powers in Star Wars. I filled it with other references to the galaxy far, far away, and submitted it to nine journals under the names of Dr Lucas McGeorge and Dr Annette Kin.

Four journals fell for the sting. The American Journal of Medical and Biological Research (SciEP) accepted the paper, but asked for a $360 fee, which I didn’t pay. Amazingly, three other journals not only accepted but actually published the spoof. Here’s the paper from the International Journal of Molecular Biology: Open Access (MedCrave), Austin Journal of Pharmacology and Therapeutics (Austin) and American Research Journal of Biosciences (ARJ) I hadn’t expected this, as all those journals charge publication fees, but I never paid them a penny.

Submission + - New Comet Discovered—May Become "One of Brightest in History" (nationalgeographic.com)

intellitech writes: From the article: 'If astronomers' early predictions hold true, the holidays next year may hold a glowing gift for stargazers—a superbright comet, just discovered streaking near Saturn. Even with powerful telescopes, comet 2012 S1 (ISON) is now just a faint glow in the constellation Cancer. But the ball of ice and rocks might become visible to the naked eye for a few months in late 2013 and early 2014—perhaps outshining the moon, astronomers say. The comet is already remarkably bright, given how far it is from the sun, astronomer Raminder Singh Samra said. What's more, 2012 S1 seems to be following the path of the Great Comet of 1680, considered one of the most spectacular ever seen from Earth.'

Submission + - Speed-of-light experiments yield baffling results (bbc.co.uk)

intellitech writes: "Puzzling results from Cern, home of the LHC, have confounded physicists — because it appears subatomic particles have exceeded the speed of light. Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away seemed to show up a few billionths of a second early. The results will soon be online to draw closer scrutiny to a result that, if true, would upend a century of physics. The lab's research director called it "an apparently unbelievable result"."

Submission + - Report Warns Space Junk Reaching Tipping Point (reuters.com)

intellitech writes: From the article: The amount of debris orbiting the Earth has reached a tipping point for collisions, which would in turn generate more debris which threatens astronauts and satellites, according to a U.S. study released on Thursday. "The current space environment is growing increasingly hazardous to spacecraft and astronauts," Donald Kessler, the former head of NASA's Orbital Debris Program Office who chaired the study team, said in a statement. In addition to more than 30 findings, the panel made two dozen recommendations for NASA to mitigate and improve the orbital debris environment, including collaborating with the State Department to develop the legal and regulatory framework for removing junk from space. The study, "Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Programs," was sponsored by NASA.

Submission + - Biological 'Computer' Destroys Cancer Cells (mit.edu)

intellitech writes: Researchers led by ETH professor Yaakov Benenson and MIT professor Ron Weiss have successfully incorporated a diagnostic biological "computer" network in human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction. In a study that has just been published in Science (abstract), they describe a multi-gene synthetic "circuit" whose task is to distinguish between cancer and healthy cells and subsequently target cancer cells for destruction. This circuit works by sampling and integrating five intracellular cancer-specific molecular factors and their concentration. The circuit makes a positive identification only when all factors are present in the cell, resulting in a highly precise cancer detection. Researchers hope that it can serve a basis for very specific anti-cancer treatments.

Submission + - Alloy Could Produce Hydrogen Fuel Using Sunlight (sciencedaily.com)

intellitech writes: Using state-of-the-art theoretical computations, the University of Kentucky-University of Louisville team demonstrated that an alloy formed by a 2 percent substitution of antimony (Sb) in gallium nitride (GaN) has the right electrical properties to enable solar light energy to split water molecules into hydrogen and oxygen, a process known as photoelectrochemical (PEC) water splitting. When the alloy is immersed in water and exposed to sunlight, the chemical bond between the hydrogen and oxygen molecules in water is broken. Because pure hydrogen gas is not found in free abundance on Earth, it must be manufactured by unlocking it from other compounds. Thus, hydrogen is not considered an energy source, but rather an "energy carrier." Currently, it takes a large amount of electricity to generate hydrogen by water splitting. As a consequence, most of the hydrogen manufactured today is derived from non-renewable sources such as coal and natural gas. The team says the GaN-Sb alloy has the potential to convert solar energy into an economical, carbon-free source for hydrogen.

Submission + - New Spin on Graphene Makes It Magnetic (sciencedaily.com)

intellitech writes: A team led by Professor Andre Geim, a recipient of the 2010 Nobel Prize for graphene, has shown that electric current can magnetize graphene. The researchers found a new way to interconnect spin and charge by applying a relatively weak magnetic field to graphene and found that this causes a flow of spins in the direction perpendicular to electric current, making a graphene sheet magnetised.

Submission + - Atomic Antennae Transmit Quantum Information (sciencedaily.com)

intellitech writes: The Austrian research group led by physicist Rainer Blatt suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennae, which enable the exchange of quantum information between two separate memory cells located on a computer chip. This offers new opportunities to build practical quantum computers.

Submission + - Frictionless Superfluid Found in Neutron Star Core (sciencedaily.com)

intellitech writes: NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in laboratories on Earth exhibit remarkable properties, such as the ability to climb upward and escape airtight containers. The finding has important implications for understanding nuclear interactions in matter at the highest known densities.

Submission + - Earth's inner core rotation slower than estimated (dailymail.co.uk)

intellitech writes: According to the Daily Mail, scientists at the University of Cambridge believe they have achieved the first accurate estimate of how much faster Earth's core is rotating compared to the rest of the planet. The rate—about one degree every million years—is much slower than previously thought and arises from the complex dynamic between Earth's inner and outer core, which generates Earth's geomagnetic field. Without our magnetic field, Earth's surface would not be protected from charged particles spewing from the Sun, and life would not be able to exist. The researchers' results were published in Nature Geoscience.

Submission + - Physicists Build Bigger 'Bottles' of Antimatter (sciencedaily.com) 1

intellitech writes: Once regarded as the stuff of science fiction, antimatter — the mirror image of the ordinary matter in our observable universe — is now the focus of laboratory studies around the world. While physicists routinely produce antimatter with radioisotopes and particle colliders, cooling these antiparticles and containing them for any length of time is another story. Clifford Surko, a professor of physics at UC San Diego, who is constructing what he hopes will be the world's largest antimatter container, said physicists have recently developed new methods to make special states of antimatter in which they can create large clouds of antiparticles, compress them and make specially tailored beams for a variety of uses.

Submission + - Shocking Images Show Gulf Bottom Still Dead (dailymail.co.uk)

intellitech writes: The Daily Mail is reporting that much of the oil from the BP spill remains stuck on the bottom of the Gulf of Mexico. At a science conference in Washington today, Joye, a professor at the University of Georgia aired early results of her December submarine dives around the BP spill site. She went to places she had visited in the summer and expected the oil and residue from oil-munching microbes would be gone by then. It wasn't. New images from her submarine dives reveal a startling absence of life on the bottom of the Gulf.
