Crowdsourced Effort May Have Found Soviet Mars Mission's Remains11

Posted by timothyon Saturday April 13, @07:20AM
from the crispy-on-the-outside dept.

A story at Slashgear says that the remains of a Soviet mission to Mars may have been spotted — on Mars — by enthusiasts poring over old photos taken by a NASA orbiter. The article points out that the find must be confirmed by further imaging, but matches the seekers' expectations. From the article: "The community at VK.com/Curiosity_Live crowdsourced a mission to find the Soviet Union’s long-lost Mars 3 spacecraft, with the site’s leader, Vitali Egorov of St. Petersburg, Russia, creating models of what hardware from the spacecraft should look like. With this reference, the community combed through a large image taken five years ago by NASA’s MRO, identifying what is believed to be the craft’s parachute, lander, terminal retrorocket, and heat shield."

alancronin writes with this excerpt from CNet:"Stephen Hawking, one of the world's greatest physicists and cosmologists, is once again warning his fellow humans that our extinction is on the horizon unless we figure out a way to live in space. Not known for conspiracy theories, Hawking's rationale is that the Earth is far too delicate a planet to continue to withstand the barrage of human battering. 'We must continue to go into space for humanity,' Hawking said today, according to the Los Angeles Times. 'We won't survive another 1,000 years without escaping our fragile planet.'"

 

Ask Slashdot: What Should Happen To Your Data After You Die?111

from the it-is-your-solemn-duty-to-clear-your-departed-best-friend's-browsing-history dept.

Nerval's Lobster writes "Death is Nature's way of telling you it's time to get off the Internet. But when you finally shuffle off this mortal coil, you leave something behind: all your email and other digital assets. That's a huge problem not only for the deceased — once you're on the wrong side of the Great Beyond, there's no way to delete those incriminating messages — but also any relatives who might want to access your (former) life. And it's a problem Google's seeking to solve with the new Inactive Account Manager. (In an April 11 blog posting, Google product manager Andreas Tuerk suggested that Inactive Account Manager wasn't a 'great name' for the product, but maybe the company shouldn't be so hard on itself: it's a way better name than, say, Google Death Dashboard.) Inactive Account Manager will delete your Google-related data (Gmail, etc.) after a set amount of time, or else send that data to 'trusted contacts' you set up before your untimely demise. Which raises an interesting, semi-Google-related question: What do you want to have happen to your data after you die? Give it to loved ones, or have an automated system nuke it all? Should more companies that host email and data offer plans like Inactive Account Manager?"

 

From the third (last) article, "...Google product manager Andreas Tuerk suggested that Inactive Account Manager wasn't a 'great name' for the product, but maybe the company shouldn't be so hard on itself: it's a way better name than, say, Google Death Dashboard."

I disagree. I think that "Google Death Dashboard" has a certain flair!

Listen to the Big Bang

Listening to the Big Bang – in high fidelity (audio)

 By Vince Stricherz         

News and Information

A decade ago, spurred by a question for a fifth-grade science project, University of Washington physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago.

....

As the universe cooled and expanded, it stretched the wavelengths to create “more of a bass instrument,” Cramer said. The sound gets lower as the wavelengths are stretched farther, and at first it gets louder but then gradually fades. The sound was, in fact, so “bass” that he had to boost the frequency 100 septillion times (that’s a 100 followed by 24 more zeroes) just to get the recordings into a range where they can be heard by humans.

"Lazarus Project" Clones Extinct Frog71

Posted by samzenpuson Monday March 18, @09:39AM
from the welcome-back dept.

cylonlover writes "Australian scientists have successfully revived and reactivated the genome of an extinct frog. The 'Lazarus Project' team implanted cell nuclei from tissues collected in the 1970s and kept in a conventional deep freezer for 40 years into donor eggs from a distantly-related frog. Some of the eggs spontaneously began to divide and grow to early embryo stage with tests confirming the dividing cells contained genetic material from the extinct frog. The extinct frog in question is the Rheobatrachus silus, one of only two species of gastric-brooding frogs, or Platypus frogs, native to Queensland, Australia. Both species became extinct in the mid-1980s and were unique amongst frog species for the way in which they incubated their offspring."

Man Has 75% of Skull Replaced By 3D-Printed Materials72

Posted by Soulskillon Friday March 08, @05:22PM
from the i-wonder-if-they'll-do-customized-designs dept.

redletterdave writes "An un-named male patient in the U.S. has had 75 percent of his skull replaced with 3D printed materials. The undisclosed patient had his head imaged by a 3D scanner before South Windsor, Conn.-based Oxford Performance Materials (OPM) gained approval from US regulators to print the bone replacement. OPM's final skull replacement was built within two weeks, and inserted in the patient's skull in an operation performed earlier this week; this cutting-edge procedure was only just revealed on Friday. OPM's 3D-printed process was granted approval by the FDA back on Feb. 18, which means the company can now provide 3D printed replacements for bones damaged by trauma or even disease. The company says this technique could benefit more than 500 U.S. citizens each month, from injured factory or construction workers to wounded soldiers."

Court: 4th Amendment Applies At Border, Password Protected Files Not Suspicious170

Posted by Soulskillon Friday March 08, @06:45PM
from the you're-doing-it-right dept.

An anonymous reader sends this Techdirt report on a welcome ruling from the 9th Circuit Court of Appeals: ""Here's a surprise ruling. For many years we've written about how troubling it is that Homeland Security agents are able to search the contents of electronic devices, such as computers and phones at the border, without any reason. The 4th Amendment only allows reasonable searches, usually with a warrant. But the general argument has long been that, when you're at the border, you're not in the country and the 4th Amendment doesn't apply. This rule has been stretched at times, including the ability to take your computer and devices into the country and search it there, while still considering it a "border search," for which the lower standards apply. Just about a month ago, we noted that Homeland Security saw no reason to change this policy. Well, now they might have to. In a somewhat surprising 9th Circuit ruling (en banc, or in front of the entire set of judges), the court ruled that the 4th Amendment does apply at the border, that agents do need to recognize there's an expectation of privacy, and cannot do a search without reason. Furthermore, they noted that merely encrypting a file with a password is not enough to trigger suspicion."

Obama Administration Supports Journalist Arrested For Recording Cops211

Posted by Soulskillon Friday March 08, @06:05PM
from the to-protect-and-serve dept.

New submitter SplatMan_DK writes "Ars Technica reports that the Obama Administration has filed a brief in support of a Maryland photojournalist who says he was arrested and beaten after he took photographs of the police arresting two other men. The brief by the Justice Department argues that the U.S. Constitution protects the right to photograph the actions of police officers in public places and prohibits police officers from arresting journalists for exercising those rights. Context: 'Garcia says that when Officer Christopher Malouf approached him, Garcia identified himself as a member of the press and held up his hands to show he was only holding a camera. But Malouf "placed Mr. Garcia in a choke hold and dragged him across the street to his police cruiser," where he "subjected him to verbal and physical abuse." According to Garcia's complaint, Malouf "forcibly dragged Mr. Garcia across the street, throwing him to the ground along the way, inflicting significant injuries." Garcia says Malouf "kicked his right foot out from under him, causing Mr. Garcia to hit his head on the police cruiser while falling to the ground." Garcia claims that Malouf took the video card from Garcia's camera and put it in his pocket. The card was never returned. Garcia was charged with disorderly conduct. In December 2011, a judge found Garcia not guilty.'"

Tech Leaders Create Most Lucrative Science Prize In History116

from the bucks-for-brains dept.

redletterdave writes "Mark Zuckerberg, Sergey Brin and Yuri Milner have teamed up to create The Breakthrough Prize in Life Sciences Foundation, which now offers the most lucrative annual prize in the history of science: A $33 million pot to be split among 11 people, with individual rewards worth $3 million apiece. Comparatively, the monetary value of the Nobel prize is just $1.1 million. 'Our society needs more heroes who are scientists, researchers and engineers,' Zuckerberg said. 'We need to celebrate and reward the people who cure diseases, expand our understanding of humanity and work to improve people's lives.'"

It's about time some of the folks who have the big bucks recognize the worth of scientific research and development. Yay for Zuckerberg, Brin, and Milner!

Boeing Engineers Use Spuds to Improve in-Air Wi-Fi

by Jason Keyser, Associated Press

CHICAGO December 23, 2012

....

While major airlines offer in-flight Wi-Fi on many flights, the signal strength can be spotty. Airlines and aircraft makers have been striving to improve this with the growing use of wireless devices and the number of people who don't want to be disconnected, even 35,000 feet up.

Engineers at Chicago-based Boeing Co. used sacks of potatoes as stand-ins for passengers as they worked to eliminate weak spots in in-flight wireless signals. They needed full planes to get accurate results during signal testing, but they couldn't ask people to sit motionless for days while data was [sic] gathered.

....

It turns out that potatoes — because of their water content and chemistry — absorb and reflect radio wave signals much the same way as the human body does, making them suitable substitutes for airline passengers.

....

In a nod to the humor in using a tuber to solve a high-tech problem, researchers dubbed the project Synthetic Personnel Using Dialectic Substitution, or SPUDS.

....

A hat tip to Hunky Husband for emailing me a link to the article. In the interest of full disclosure, HH spent just shy of 35 years (Feb 1959 - Sep 1993) with Boeing. HH, being a pharmacist student gone bad, did most of his university work in electronics engineering and worked in avionics* engineering (1959 - 1974) and program management (1975 - 1993).

cylonlover writes "Flush with success from their 6,000-km (3,728-mile) Europe-to-Africa round-trip flight earlier this year, the duo behind the Solar Impulse solar-powered aircraft are now planning on flying it across America next spring. It will mark the first time that a solar-powered plane has traversed the country. Solar Impulse partners Bertrand Piccard and André Borschberg made the official announcement this Tuesday, although the logistics of the flight have yet to be finalized. They have stated that the trip will be broken into 20-hour legs, starting at San Francisco and proceeding to New York City. As with their previous multi-leg flights, the two pilots will take turns flying the aircraft." You can read about it straight from the doers, too.

Portrait of Global Aerosols

High-resolution global atmospheric modeling provides a unique tool to study the role of weather within Earth's climate system. The Goddard Earth Observing System Model, Version 5 (GEOS-5) is capable of simulating worldwide weather at resolutions of 10 to 3.5 kilometers (km).

This portrait of global aerosols [Note: not used, in this instance, to denote hydrofluorocarbons and other man-made aerosols - CC] was produced by a GEOS-5 simulation at a 10-kilometer resolution. Dust (red) is lifted from the surface, sea salt (blue) swirls inside cyclones, smoke (green) rises from fires, and sulfate particles (white) stream from volcanoes and fossil fuel emissions.

Large Hadron Collider May Have Produced New Matter43

Posted by Soulskillon Tuesday November 27, @04:00PM
from the news-for-nerds-stuff-that's-matter dept.

Covalent writes "The Large Hadron Collider, the world's largest and most powerful particle accelerator and the 'Big Bang machine' that was used to discover what appears to be the long-sought Higgs boson particle (as announced July 4), may have another surprise up its sleeve this year: The LHC looks to have produced a new type of matter, according to a new analysis of particle collision data by scientists at MIT and Rice University. The new type of matter, which has yet to be verified, is theorized to be one of two possible forms: Either 'color-glass condensate' — a flattened nucleus transformed into a 'wall' of gluons, which are smaller binding subatomic particles, or it could be 'quark-gluon plasma,' a dense, soup or liquid-like collection of individual particles."

How Do We Program Moral Machines?266

nicholast writes "If your driverless car is about to crash into a bus, should it veer off a bridge? NYU Prof. Gary Marcus has a good essay about the need to program ethics and morality into our future machines. Quoting: 'Within two or three decades the difference between automated driving and human driving will be so great you may not be legally allowed to drive your own car, and even if you are allowed, it would immoral of you to drive, because the risk of you hurting yourself or another person will be far greater than if you allowed a machine to do the work. That moment will be significant not just because it will signal the end of one more human niche, but because it will signal the beginning of another: the era in which it will no longer be optional for machines to have ethical systems.'"

What Will NASA Do With Its Gifted Spy 'Scopes?90

astroengine writes "NASA has begun surveying scientists on what they would like to do with two Hubble-class space telescopes donated to the civilian space agency by its secretive sibling, the National Reconnaissance Office — which operates the nation's spy satellites. But the gifts have some formidable strings attached, including costs to develop instruments and launch the observatories. The telescopes, though declassified, also are subject to export regulations. 'We need to retain possession and control,' NASA's astrophysics division director Paul Hertz told Discovery News. 'That doesn't preclude us from partnering (with other countries). It just sets boundaries on the nature of the partnership.' NASA also isn't allowed to use the telescopes for any Earth-observing missions. Topping the list of possible missions for the donor hardware is a remake of NASA's planned Wide-Field Infrared Survey Telescope, known as WFIRST. The mission, estimated to cost between $1.5 billion and $2 billion, is intended to answer questions about dark energy, a relatively recently discovered phenomenon that is believed to be speeding up the universe's rate of expansion."

Hairspray Could Help Us Find Advanced Alien Civilizations164

Posted by Unknown Lameron Tuesday November 27, @08:03AM
from the at-least-the-fashionable-ones dept.

Hugh Pickens writes "Charles Q. Choi reports that hairspray could one day serve as the sign that aliens have reshaped distant worlds because one group of gases that might be key to terraforming planets are CFCs. 'Our hypothesis is that evidence of intelligent life might be evident in a planetary atmosphere,' says astrobiologist Mark Claire at the Blue Marble Space Institute of Science. CFCs are entirely artificial, with no known natural process capable of creating them in atmospheres. Detecting signs of these gases on far-off worlds with telescopes might serve as potent evidence that intelligent alien civilizations were the cause, either intentionally as part of terraforming or accidentally via industrial pollution. 'An industrialized civilization will be one that will use its planetary resources for fabrication, the soon-to-be-detectable-from-Earth atmospheric byproducts of which could be a tell-tale sign of their activity,' says astrobiologist Sanjoy Som. CFCs can be easily recognized in planetary atmospheres because their atmospheric 'fingerprint' (i.e. chemical spectra) is very different from natural elements, and are a tell-tale sign that life on the surface has advanced industrial capabilities. Using state-of-the-art computer models of atmospheric chemistry and climate, researchers plan to discover what visible signs CFCs and other artificial byproducts of alien terraforming or industry might have on exoplanet atmospheres. 'We are about a decade away of being able to measure detailed compositions of the atmospheres of extrasolar planets,' says Som."

Particle Physicists Confirm Arrow of Time Using B Meson Measurements108

Posted by Unknown Lameron Monday November 19, @06:50PM
from the one-way-trip dept.

ananyo writes with bad news for John Titor. From the article: "Four years after its closure, researchers working with data from the Stanford Linear Accelerator Center's particle physics experiment BaBar have used the data to make the first direct measurement confirming that time does not run the same forwards as backwards — at least for the B mesons that the experiment produced during its heyday. The application of quantum mechanics to fundamental particles rests on a symmetry known as CPT, for charge-parity-time, which states that fundamental processes remain unchanged when particles are replaced by their antimatter counterparts (C), left and right are reversed (P), and time runs in the reverse direction (T). Violations of C and P alone were first seen in radioactive decays in the 1950s, and BaBar was used to confirm violations of CP in B meson decays in 2001. To keep CPT intact, that implies that time reversal is also violated, but finding ways to compare processes running forward and backward in time has proven tricky. Theoretical physicists at the Universityof Valencia in Spain worked with researchers on BaBar to exploit the fact that the experiment had generated entangled quantum states of the meson Bzero and its antimatter counterpart Bzero-bar, which then evolved through several different decay chains. By comparing the rates of decay in chains in which one type of decay happened before another, with others in which the order was reversed, the researchers were able to compare processes that were effectively time reversed version of each other. They report in Physical Review Letters today that they see a violation of time reversal at an extremely high level of statistical significance."

thomst writes "Tim Wogan reports that chemical engineer Zhenan Bao of Stanford University in Palo Alto, California, and her team have increased the conductivity of a self-healing polymer by incorporating nickel atoms. The polymer they have produced is sensitive to applied forces like pressure and torsion (twisting) because such forces alter the distance between the nickel atoms, changing the electrical resistance of the polymer. Their work is published online in the November 1 issue of Nature Nanotechnology (abstract here, full article paywalled). Now Bao and her team are working on making the polymer more flexible."

Supersymmetry Theory Dealt a Blow118

from the state-of-things dept.

Dupple writes in with some news from the team at the Large Hadron Collider. "Researchers at the Large Hadron Collider have detected one of the rarest particle decays seen in Nature. The finding deals a significant blow to the theory of physics known as supersymmetry. Many researchers had hoped the LHC would have confirmed this by now. Supersymmetry, or SUSY, has gained popularity as a way to explain some of the inconsistencies in the traditional theory of subatomic physics known as the Standard Model. The new observation, reported at the Hadron Collider Physics conference in Kyoto, is not consistent with many of the most likely models of SUSY. Prof Chris Parke, who is the spokesperson for the UK Participation in the LHCb experiment, told BBC News: 'Supersymmetry may not be dead but these latest results have certainly put it into hospital.'"
