schwit1 writes with a report that an early 20th century experiment has generated a belated data point. One of many floating bottles released 108 years ago to study currents was recently found by a German couple; it washed up on a beach in Amrum, Germany. From The Independent: When the couple unfurled the note inside, they found a message in English, German and Dutch. It asked the finder to fill in some information on where and when they had found the bottle, before returning it to the Marine Biological Association in Plymouth. It said whoever did so would be rewarded with one shilling. Communications director of the Marine Biological Association, Guy Baker, told The Daily Telegraph: "It was quite a stir when we opened that envelope, as you can imagine." Once at the association, staff recognised the bottle was one of 1,020 released into the North Sea between 1904 and 1906 as part of a project to test the strength of currents. Mr Baker told the paper: "It was a time when they were inventing ways to investigate what currents and fish did. Many of the bottles were found by fishermen trawling with deep sea nets. Others washed up on the shore, and some were never recovered. Most of the bottles were found within a relatively short time. We're talking months rather than decades."
StartsWithABang writes: It's been 13.8 billion years since the Big Bang for us, and when we look out at a distant object in the Universe, we're seeing it as it was in the past. Its age — as it appears — is determined only by how long the light took for it to travel from that object to our eyes, but to someone living there, it will also appear that the Universe is 13.8 billion years old. But it is actually possible for an observer living on another planet, star or galaxy to perceive that significantly less time has passed since the Big Bang, so long as they were moving close to the speed of light relative to the CMB. Paradoxically, if they slowed their speed, they'd find that they themselves were very young, but living in a 13.8 billion year-old Universe.
In 2013, the IceCube neutrino telescope detected dozens of high-energy neutrinos. Now, reports Astronomy magazine, researchers "have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of [those] 2013 observations confirming the existence of cosmic neutrinos." According to the report, Albrecht Karle from UW-Madison notes that while the neutrino-induced tracks recorded by the IceCube detector have a good pointing resolution, within less than a degree, the IceCube team has not observed a significant number of neutrinos emanating from any single source. ... “The plane of the galaxy is where the stars are. It is where cosmic rays are accelerated, so you would expect to see more sources there. But the highest-energy neutrinos we’ve observed come from random directions,” said Karle. “It is sound confirmation that the discovery of cosmic neutrinos from beyond our galaxy is real.”

The researchers compared the cellphone analysis with a highly detailed dataset on rubella incidence in Kenya. They matched; the cellphone movement patterns lined up with the rubella incidence figures. In both of their analyses, rubella spiked three times a year. This showed the researchers that cellphone movement can be a predictor of infectious-disease spread.
John S. Lewis -- Deep Space Industries' chief scientist, author, and University of Arizona professor -- speaks in an interview with Air & Space magazine about the practicalities and possibilities of deep-space mining, a topic on which he is unapologetically bullish. He points out, though, that some of the artist's-conception version of space mining skips over some of the economic realities of getting back to Earth metals that are scarce here. From the interview: But—and here’s the big conditional—if we develop an industrial capability in space such that we’re processing large amounts of metals to make solar-powered satellites, for example, then as a byproduct, we would have very substantial quantities of platinum-group metals, which are extremely valuable. So if you have a market for the iron and the nickel in space, that would liberate the precious metals to be brought back to Earth. So the scheme is not based on the idea of retrieving platinum-group metals—that is simply gravy."
schwit1 writes: An experiment to test how whiskey ages in weightlessness is about to begin on ISS: "H-II Transfer Vehicle No. 5, commonly known as "Kounotori5" or HTV5, was launched on Wednesday from JAXA's Tanegashima Space Center carrying alcohol beverages produced by Suntory to the Japanese Experiment Module aboard the International Space Station, where experiments on the "development of mellowness" will be conducted for a period of about one year in Group 1 and for two or more years (undecided) in Group 2." Don't worry, the astronauts on ISS won't be getting drunk. After the test period is complete the samples will then returned to Earth, untasted, where they will then be compared with control samples.
zdburke writes: Thanks to improvements in satellites and on-the-ground computing power, NASA's ability to model hurricane data has come a long way in the ten years since Katrina devastated New Orleans. Their blog notes, "Today's models have up to ten times the resolution than those during Hurricane Katrina and allow for a more accurate look inside the hurricane. Imagine going from video game figures made of large chunky blocks to detailed human characters that visibly show beads of sweat on their forehead." Gizmodo covered the post too and added some technical details, noting that, "the supercomputer has more than 45,000 processor cores and runs at 1.995 petfalops."
An anonymous reader writes: On October 2, movie audiences will get to see Ridley Scott's adaptation of Andy Weir's brilliant sci-fi novel The Martian, about a near-future astronaut who gets left for dead on the planet Mars. (Official trailer.) Both book and film are rooted in actual science, and NASA has now posted a list of technologies featured in the movie that either already exist, or are in development. For example, the Mars rover: "On Earth today, NASA is working to prepare for every encounter with the Multi-Mission Space Exploration Vehicle (MMSEV). The MMSEV has been used in NASA's analog mission projects to help solve problems that the agency is aware of and to reveal some that may be hidden. The technologies are developed to be versatile enough to support missions to an asteroid, Mars, its moons and other missions in the future." They also show off their efforts to develop water reclamation, gardens in space, and oxygen recovery.
jan_jes writes: A team of scientists at the Wyss Institute last year described the development of a device to treat sepsis that works by mimicking the human spleen. The device cleanses pathogens and toxins from blood flowing through a dialysis-like circuit. Now the team has developed an improved device that works with conventional antibiotic therapies and is better positioned for near-term use in clinics. The improved design will be described in the October issue of Biomaterials. This approach can be administered quickly, even without identifying the infectious agent.
derekmead writes: NASA launched the Viking 1 spacecraft to Mars forty years ago. The probe was the first to achieve a soft landing on the planet, providing the first images and data from Mars. Politically the Viking 1 success was a huge win for the U.S. against the competing Soviet space program. Motherboard reports: "Viking 1 went on to become one of the most productive landers ever deployed on Mars, operating for 2,307 days before it finally shut down on November 13, 1982. It held the record for the longest Martian surface mission for decades, until the Opportunity rover finally beat it out in 2010 (and that little trooper is still going, by the way)."
New submitter ahbond writes: The meme of the chubby nerd alone in the basement may be a thing of the past. Well, at least the chubby part, if recent work at MIT pans out and we're able to use a biological "master switch" to "dial-in" a persons metabolic rate. “Obesity has traditionally been seen as the result of an imbalance between the amount of food we eat and how much we exercise, but this view ignores the contribution of genetics to each individual’s metabolism,” said senior author Manolis Kellis, a professor of computer science and a member of MIT’s Computer Science and Artificial Intelligence Laboratory and of the Broad Institute.
Lucas123 writes: Intel and the Knight Cancer Institute have announced what will be an open-source service platform, called the Collaborative Cancer Cloud. The platform will enable healthcare facilities to securely share patient genomic data, radiological imagery and other healthcare-related information for precision treatment analysis. Key to averting HIPAA privacy issues will be Intel's Trusted Execution Technology, its embedded server encryption hardware that tests the authenticity of a platform and its operating system before sharing data. Intel said it will be opening that technology up for use by any clinic that want to take part in the Collaborative Cancer Cloud or to build its own data-sharing network with healthcare partners. Dr. Brian Druker, director of the Knight Cancer Institute, said the Trusted Execution Technology will allow healthcare centers to maintain control of patient data, while also allowing clinics around the world to use it for vastly faster genomic analysis.
astroengine writes: Scientists have long puzzled over how gas planets like Jupiter and Saturn got to be so big. Current theories suggest the cores of these behemoths are comprised of mini-planets, some 62- to 620 miles in diameter, which collided and gradually merged together over time. But computer simulations show this process is more likely to produce hundreds of Earth-sized worlds. Instead, a new study suggests "slow pebble accretion" is a more likely process.
nojayuk writes: There's another launcher delivering cargo to the ISS apart from US and Russian vehicles, and it's Japanese. The fifth Koutonori (White Stork) cargo vehicle was successfully launched today at from pad 2 of the Yoshinobu Launch Complex at Tanegashima south of Tokyo at 11:50:49 UTC, carrying over 5 tonnes of food, spare parts and scientific equipment to the ISS in a pressurised cabin and an external racking system. This is the fifth successful launch in a row for the Japanese H2B launcher. The Koutonoris have carried over 20 tonnes of cargo in total to the ISS, more than double the amount of SpaceX's six successful CRS resupply flights.
schwit1 writes: A major scientific publisher has retracted 64 articles in 10 journals after discovering that the so-called independent peer reviewers for these articles were fabricated by the authors themselves. From the article: "The cull comes after similar discoveries of 'fake peer review' by several other major publishers, including London-based BioMed Central, an arm of Springer, which began retracting 43 articles in March citing 'reviews from fabricated reviewers'. The practice can occur when researchers submitting a paper for publication suggest reviewers, but supply contact details for them that actually route requests for review back to the researchers themselves." Overall, this indicates an incredible amount of sloppiness and laziness in the peer-review field. In total, more than a 100 papers have been retracted, simply because the journals relied on the authors to provide them contact information for their reviewers, never bothering to contact them directly.
MarkWhittington writes: The Associated Press noted the passing of former Rep. Louis Stokes at the age of 90. Since Stokes was an African American Democrat first elected in 1968, most of the accolades touch on his effect on the civil rights struggle and his lifelong fight against racism. However, as George Abbey, former NASA Director of the Johnson Spaceflight Center and current Fellow in Space Policy at the Baker Institute of Rice University pointed out on his Facebook Page, Stokes can be rightly be said to be the man who saved the International Space Station and perhaps human space flight in America.
jones_supa writes: Researchers at Massachusetts Institute of Technology and Samsung have developed a new approach to one of the three basic components of batteries, the electrolyte. The new findings are based on the idea that a solid electrolyte, rather than liquid, could greatly improve both device lifetime and safety, while also providing a significant boost in power density. The new type of electrolyte would also cope better in cold temperatures. The results are reported in the journal Nature Materials in a paper by MIT postdoc Yan Wang, visiting professor of materials science and engineering Gerbrand Ceder, and five others.
Tarek Loubani is an emergency medicine physician who works as a consultant doctor in the emergency departments in London, Canada and Shifa Hospital in Gaza. He is also an assistant professor at the Department of Medicine at the University of Western Ontario. Tarek has been working in Gaza for the past 5 years, where he made news recently by creating a 3D-printable, 30-cent stethoscope that is better than the world's best $200 equivalent. The need to develop free and open medical devices due to the lack of medical supplies resulting from the blockade, inspired Loubani who hopes the stethoscope is just the beginning of replacing expensive proprietary medical tools. Tarek has agreed to answer any questions you might have. As usual, ask as many as you'd like, but please, one question per post.
An anonymous reader writes: Junk DNA (or noncoding DNA) is a term for section of a DNA strand that doesn't actually do much. Huge tracts of the human genome consist of junk DNA, and researchers are now finding that it may be more useful than previously thought. "For most of the last 40 years, scientists thought that [gene duplication] was the primary way new genes were born — they simply arose from copies of existing genes. The old version went on doing its job, and the new copy became free to evolve novel functions. Certain genes, however, seem to defy that origin story. They have no known relatives, and they bear no resemblance to any other gene. ... But in the past few years, a once-heretical explanation has quickly gained momentum — that many of these orphans arose out of so-called junk DNA."
schwit1 writes: A team of researchers from Ohio State University claim to have grown a human brain in their lab that approximates the brain of a five-week-old fetus. They say the tiny brain is not conscious, but it could be used to test drugs and study diseases, but scientific peers urge caution. "The brain, which is about the size of a pencil eraser, is engineered from adult human skin cells and is the most complete human brain model yet developed, [the researchers say]. ... Anand and his colleagues claim to have reproduced 99% of the brain’s diverse cell types and genes. They say their brain also contains a spinal cord, signalling circuitry and even a retina." The team's data has not yet been peer reviewed.
