Assembling a Micro-scale Biochemistry Lab Like Snapping LEGOs Together 1

Posted by Soulskill
from the probably-won't-hurt-as-much-when-you-step-on-them dept.
An anonymous reader writes: Microfluidic systems promise to bring the same level of precision and control seen in the electronics industry to chemistry and the life sciences. Typically, devices are fabricated at substantial cost and using borrowed techniques from the semiconductor industry. Researchers at the USC Viterbi School of Engineering have invented a system of discrete microfluidic elements akin to those found in electronic board design. It was inspired by the ease with which LEGO bricks are assembled into a larger structure, and finally allows for the rapid prototyping of "Lab-on-Chip" devices. The original paper is published in the Proceedings of the National Academy of Science.

Outlining Thin Linux 28

Posted by Soulskill
from the tux-on-a-diet dept.
snydeq writes: Deep End's Paul Venezia follows up his call for splitting Linux distros in two by arguing that the new shape of the Linux server is thin, light, and fine-tuned to a single purpose. "Those of us who build and maintain large-scale Linux infrastructures would be happy to see a highly specific, highly stable mainstream distro that had no desktop package or dependency support whatsoever, so was not beholden to architectural changes made due to desktop package requirements. When you're rolling out a few hundred Linux VMs locally, in the cloud, or both, you won't manually log into them, much less need any type of graphical support. Frankly, you could lose the framebuffer too; it wouldn't matter unless you were running certain tests," Venezia writes. "It's only a matter of time before a Linux distribution that caters solely to these considerations becomes mainstream and is offered alongside more traditional distributions."

Jason Koebler writes With all the conspiracy theories surrounding some high-profile deaths in recent years, how can you, theoretical whistleblower with highly sensitive documents, be assured that your information gets leaked if you're murdered in some government conspiracy? A new dark web service says it's got your back. "Dead Man Zero" claims to offer potential whistleblowers a bit more peace of mind by providing a system that will automatically publish and distribute their secrets should they die, get jailed, or get injured.

The UPS Store Will 3-D Print Stuff For You 66

Posted by samzenpus
from the quick-print dept.
mpicpp writes with news that UPS will be expanding their 3D printing services. UPS announced plans Monday to bring in-store 3-D-printing services to nearly 100 stores across the country, billing itself as the first national retailer to do so. With the UPS system, customers can submit their own designs for objects like product prototypes, engineering parts and architectural models that are then printed on a professional-quality 3-D printer made by Stratasys. Prices vary depending on the complexity of the object; an iPhone case would be about $60, while a replica femur bone would be around $325. UPS can also connect customers with outside professionals who charge an hourly rate to help produce a design file for the printer. It generally takes about four or five hours to print a simple object, with more complex items taking a day or more. The program started as a pilot at six locations last year, and UPS says those stores "saw demand for 3-D print continuing to increase across a broad spectrum of customers."

Ancient Campfires Led To the Rise of Storytelling 40

Posted by samzenpus
from the pull-up-a-stump dept.
sciencehabit writes A study of evening campfire conversations by the Ju/'hoan people of Namibia and Botswana suggests that by extending the day, fire allowed people to unleash their imaginations and tell stories, rather than merely focus on mundane topics. As scientists report, whereas daytime talk was focused almost entirely on economic issues, land rights, and complaints about other people, 81% of the firelight conversation was devoted to telling stories, including tales about people from other Ju/'hoan communities. The team suggests that campfires allowed human ancestors to expand their minds in a similar way and also solidified social networks.

Before Using StingRays, Police Must Sign NDA With FBI 59

from the the-first-rule-of-tracking-club dept.
v3rgEz writes Advanced cell phone tracking devices known as StingRays allow police nationwide to home in on suspects and to log individuals present at a given location. But before acquiring a StingRay, state and local police must sign a nondisclosure agreement with the FBI, according to documents released via a MuckRock FOIA request. As Shawn Musgrave reports, it's an unusual setup arrangement for two public agencies to swear each other to secrecy, but such maneuvers are becoming more common.

New Long-Range RFID Technology Helps Robots Find Household Objects 32

Posted by samzenpus
from the follow-the-signal dept.
HizookRobotics writes Georgia Tech researchers announced a new way robots can "sense" their surroundings through the use of small ultra-high frequency radio-frequency identification (UHF RFID) tags. Inexpensive self-adhesive tags can be stuck on objects, allowing an RFID-equipped robot to search a room for the correct tag's signal, even when the object is hidden out of sight. Once the tag is detected, the robot knows the object it's trying to find isn't far away. The researchers' methods, summarized over at IEEE: "The robot goes to the spot where it got the hottest signal from the tag it was looking for, zeroing in on it based on the signal strength that its shoulder antennas are picking up: if the right antenna is getting a stronger signal, the robot yaws right, and vice versa."

Nvidia Sinks Moon Landing Hoax Using Virtual Light 183

Posted by samzenpus
from the this-proves-nothing dept.
schwit1 writes Using its new top-shelf graphics processing unit, Nvidia tackles one of the most persistent conspiracy theories in American history: the veracity of the 1969 to 1972 Apollo moon landings. From the article: "'Global illumination is the hardest task to solve as a game company,' Scott Herkelman, Nvidia's GeForce general manager, said in an interview. 'Virtual point lights don't do a bad job when the environment stays the same, but a game developer has to fake shadows, fake reflections...it's a labor-intensive process.' So when a Nvidia research engineer used the company's new dynamic lighting techniques to show off a side-by-side comparison between an Apollo 11 photo and a GeForce-powered re-creation, the company knew it had a novel demo on its hands. 'We're going to debunk one of the biggest conspiracies in the world,' Herkelman said."

"Big Bang Signal" Could All Be Dust 71

Posted by samzenpus
from the not-so-fast dept.
An anonymous reader writes Scientists have shown that the swirl pattern touted as evidence of primordial gravitational waves — ripples in space and time dating to the universe's explosive birth — could instead all come from magnetically aligned dust. A new analysis of data from the Planck space telescope has concluded that the tiny silicate and carbonate particles spewed into interstellar space by dying stars could account for as much as 100 percent of the signal detected by the BICEP2 telescope and announced to great fanfare this spring. The Planck analysis is "relatively definitive in that we can't exclude that the entirety of our signal is from dust," said Brian Keating, an astrophysicist at the University of California, San Diego, and a member of the BICEP2 collaboration.

Bioethicist At National Institutes of Health: "Why I Hope To Die At 75" 327

Posted by samzenpus
from the end-of-the-line dept.
HughPickens.com writes Ezekiel J. Emanuel, director of the Clinical Bioethics Department at the US National Institutes of Health, writes at The Atlantic that there is a simple truth that many of us seem to resist: living too long renders many of us, if not disabled, then faltering and declining, a state that may not be worse than death but is nonetheless deprived. "It robs us of our creativity and ability to contribute to work, society, the world. It transforms how people experience us, relate to us, and, most important, remember us. We are no longer remembered as vibrant and engaged but as feeble, ineffectual, even pathetic." Emanuel says that he is isn't asking for more time than is likely nor foreshortening his life but is talking about the kind and amount of health care he will consent to after 75. "Once I have lived to 75, my approach to my health care will completely change. I won't actively end my life. But I won't try to prolong it, either." Emanuel says that Americans seem to be obsessed with exercising, doing mental puzzles, consuming various juice and protein concoctions, sticking to strict diets, and popping vitamins and supplements, all in a valiant effort to cheat death and prolong life as long as possible. "I reject this aspiration. I think this manic desperation to endlessly extend life is misguided and potentially destructive. For many reasons, 75 is a pretty good age to aim to stop."

Friendly Reminder: Do Not Place Your iPhone In a Microwave 204

Posted by samzenpus
from the bad-ideas dept.
Nerval's Lobster writes Placing your iPhone in the microwave will destroy the phone, and possibly the microwave. While that might seem obvious to some people, others have fallen for the "Wave" hoax making its way around online. The fake advertisement insists that the new iOS 8 allows users to charge their iPhones by placing them in a "household microwave for a minute and a half." Microwave energy will not charge your smartphone. To the contrary, it will scorch the device and render it inoperable. If you nuke your smartphone and subsequently complain about it online, people will probably make fun of you. (If you want a full list of things not to place in a microwave, no matter how pretty the flames, check this out.)

Astrophysicists Identify the Habitable Regions of the Entire Universe 69

Posted by samzenpus
from the good-neighborhood dept.
KentuckyFC writes It's not just star systems and galaxies that have habitable zones--regions where conditions are suitable for life to evolve. Astrophysicists have now identified the entire universe's habitable zones. Their approach starts by considering the radiation produced by gamma ray bursts in events such as the death of stars and the collisions between black holes and so on. Astrobiologists have long known that these events are capable of causing mass extinctions by stripping a planet of its ozone layer and exposing the surface to lethal levels of radiation. The likelihood of being hit depends on the density of stars, which is why the center of galaxies are thought to be inhospitable to life. The new work focuses on the threat galaxies pose to each other, which turns out to be considerable when they are densely packed together. Astronomers know that the distribution of galaxies is a kind of web-like structure with dense knots of them connected by filaments interspersed with voids where galaxies are rare. The team says that life-friendly galaxies are most likely to exist in the low density regions of the universe in the voids and filaments of the cosmic web. The Milky Way is in one of these low density regions with Andromeda too far away to pose any threat. But conditions might not be so life friendly in our nearest knot of galaxies called the Virgo supercluster."
