Thousands of Lab Mice Lost In Sandy Flooding 88

Posted by Soulskill
from the george-bush-doesn't-care-about-mouse-people dept.
An anonymous reader writes "While New York University's Langone Medical Center in lower Manhattan was the site of heroism as 260 patients were evacuated from flooded floors and a nearly complete loss of power, similar floods at NYU's nearby Smilow Research Building killed thousands of laboratory mice, including genetically altered specimens in-bred over many generations as research subjects for melanoma and other diseases. Other laboratory animals, cells, and living tissue used in medical research were also lost; because of the gestation period involved, some projects were likely set back a number of years. Past experience with storms such as Allison in Houston and Katrina in New Orleans has shown that keeping laboratory animals in basements is not good practice, but research institutions keep doing it anyway."

VR Tech Lets People Interact With Rats 33

Posted by Soulskill
from the why?-who-knows dept.
cylonlover writes "The EU Commission's Community Research and Development Information Service (CORDIS) is working on a 'beaming' telepresence system that is designed to allow users to virtually experience being in a remote location by seeing, hearing and even feeling that location through the sensory inputs of a robot located there. That robot, in turn, would relay the user's speech and movements to the people at that location. Now, two of the CORDIS partners have put an interesting slant on the technology – they've used it to let people interact with rats."

Massachusetts May Soon Change How the Nation Dies 439

Posted by Soulskill
from the i-bet-it-involves-the-red-sox dept.
Hugh Pickens writes "Lewis M. Cohen reports that this Election Day, Massachusetts is poised to approve the Death With Dignity Act, a modernized, sanitized, politically palatable term that replaces the now-antiquated expression 'physician-assisted suicide.' Oregon's Death With Dignity Act has been in effect for the past 14 years, and the state of Washington followed suit with a similar law in 2008. But the Massachusetts ballot question has the potential to turn death with dignity from a legislative experiment into the new national norm, because the state is the home of America's leading medical publication (the New England Journal of Medicine), hospital (Massachusetts General), and four medical schools (Harvard, Boston University, University of Massachusetts, and Tufts). If the act passes in Massachusetts, other states that have previously had unsuccessful campaigns will certainly be emboldened to revisit this subject. The initiative would allow terminally ill patients with six months or less to live to request from their doctor a prescription for a lethal dose of a drug. Doctors do not have to offer the option at all, and patients must make three requests, two verbal and one written. They must self-administer the drug, which would be ingested. The patients must be deemed capable of making an informed decision. 'It's all about choice,' says George Eighmey, a key player in instituting the Oregon law, defending it against repeal and shepherding it into reality. 'You decide. No one else can decide for you. No can can force you into it, coerce you into it or even suggest it to you unless you make a statement: "I don't want to live like this any more" or "I'm interested in that law out there, doctor, can you give me something to alleviate this pain and suffering."'"

Crushed Silicon Triples Life of Li-Ion Batteries In the Lab 123

Posted by Soulskill
from the get-me-a-hammer dept.
derekmead writes "Batteries rule everything around us, which makes breakthroughs a big deal. A research team at Rice says they have produced a nice jump: by using a crushed silicon anode in a lithium-ion battery, they claim to have nearly tripled the energy density of current li-ion designs. Engineer Sibani Lisa Biswal and research scientist Madhuri Thakur reported in Nature's Scientific Reports (it has yet to be published online) that by taking porous silicon and crushing it, they were able to dramatically decrease the volume required for anode material. Silicon has long been looked at as an anode material because it holds up to ten times more lithium ions than graphite, which is most commonly used commercially. But it's previously been difficult to create a silicon anode with enough surface area to cycle reliably. Silicon also expands when it's lithiated, making it harder to produce a dense anode material. After previously testing a porous silicon 'sponge,' the duo decided to try crushing the sponges to make them more compact. The result is a new battery design that holds a charge of 1,000 milliamp hours per gram through 600 tested charge cycles of two hours charging, two hours discharging. According to the team, current graphite anodes can only handle 350 mAh/g."

Volcano Power Plan Gets US Go-Ahead 114

from the lets-get-cooking dept.
cylonlover writes "Having successfully negotiated the challenging regulatory slopes of the U.S. Bureau of Land Management, the U.S. Forest Service, the U.S. Department of Energy, and a host of Oregon state agencies, the Newberry Enhanced Geothermal Systems (EGS) demonstration project is in the process of creating a new geothermal reservoir in central Oregon. The core of the new reservoir is a two mile (3.2 km) deep well drilled about four miles (6.4 km) from the center of Newberry Volcano. The rock surrounding the wellbore reaches temperatures in the order of 600 F (300 C), and is nearly impermeable to water. That, however, is about to change. Newberry Volcano is one of the largest and youngest volcanoes in the United States. Having last erupted about 1,300 years ago, it consists of over 400 individual volcanic vents, which, when combined, form a broad mounded landform referred to as a shield volcano. The Newberry EGS Demonstration geothermal reservoir is being formed in the high-temperature, low-permeability deep lava of the volcano's northwest flank."

Artificial Misting System Allows Reintroduction of Extinct Toad 121

Posted by samzenpus
from the spritzing-back-to-life dept.
terrancem writes "The Kihansi Spray Toad went extinct in the wild in 2005 when its habitat in Tanzania was destroyed by a dam. However conservationists at the Bronx Zoo managed to maintain a captive population which is now large enough to allow a bold experiment to move forward: reintroducing the toad into its old habitat. To make the once tropical gorge moist again, engineers have designed an artificial misting system that should allow toads to survive in the wild. The effort marks what may be the first time conservationists have ever re-established an 'extinct' species in a human-engineered ecosystem."

Has the Mars Rover Sniffed Methane? 119

Posted by samzenpus
from the smells-like-gene-spirit dept.
First time accepted submitter GrimAndBearIt writes "NASA's Curiosity rover is poised to settle years of debate on the question of atmospheric methane on Mars, which would be a sign of microbial life. With parts per trillion sensitivity, it's not so much a question of whether the rover will be able to smell trace amounts of methane, but rather a question of how much. NASA has announced that Grotzinger's team will discuss atmospheric measurements at a briefing on 2 November. If the rover has detected methane at sufficiently high concentration, or exhibiting temporal variations of the kind that suggests microbial activity, then it will surely motivate a desire to identify and map the sources."

MOCR2 was used to control almost manned Gemini and Apollo mission, including Apollo 11 & 13. More, my tour guide was none other than famous Apollo mission controller Sy Liebergot, one of the fellows behind the solution that saved Apollo 13. I go in-depth on the role of the flight controller during Apollo, and focus on how and why Mission Control functioned, and I spend a lot of time talking about the consoles and how they worked. The feature includes a ton of anecdotes and stories from Mr. Liebergot about mission control in general, and about what he did during Apollo 12 & 13 specifically. I also put together a supplemental report that goes through each and every station and describes their Apollo-era layout."

chicksdaddy writes "The steady drumbeat of disturbing news about vulnerable, IP enabled medical devices continues this week, after medical device maker Hospira said it has issued a voluntary recall of its Symbiq-brand drug infusion pumps after discovering a software error that may cause touch interfaces on the pumps to not respond to user touches or to display dosage information that is inaccurate. The problem was detected in around 1.5% of Symbiq One Channel and Two Channel Infusers (model numbers 16026 and 16027), but could potentially affect 'all Symbiq infusion systems currently in the field.' The software bug could result in 'a delayed response and or the screen registering a different value from the value selected by the user,' the company said in a statement."

SchrodingerZ writes "The now decommissioned Space Shuttle Enterprise appears to have been damaged by super storm Sandy, as it blew through New York City. The shuttle is currently on display on the deck of the USS Intrepid, as part of the Sea, Air, and Space museum on pier 86. The storm tore through the shuttle's inflatable pavilion which housed it, leaving a deflated mess over the space craft. It appears that the pavilion has damaged the vertical stabilizer on the tail of the craft. The museum has yet to comment on the situation. This is not the first time the Enterprise has been damaged however. As it was being towed through Jamaica Bay en route to its new home in Manhattan, the barge was hit by wind and forced the spacecraft's wingtip into a railroad bridge pylon ."

concealment writes in with a story about a man who has been crowned the world's happiest. "Tibetan monk and molecular geneticist Matthieu Ricard is the happiest man in the world according to researchers at the University of Wisconsin. The 66-year-old's brain produces a level of gamma waves — those linked to consciousness, attention, learning and memory — never before reported in neuroscience. The scans showed that when meditating on compassion, Ricard's brain produces a level of gamma waves — those linked to consciousness, attention, learning and memory — 'never reported before in the neuroscience literature,' Davidson said. The scans also showed excessive activity in his brain's left pre-frontal cortex compared to its right counterpart, giving him an abnormally large capacity for happiness and a reduced propensity towards negativity, researchers believe."

An anonymous reader writes "Mathematician Benjamin K. Tippett has written a fascinating and deadpan paper (Pdf) giving insights into Cthulhu. A 'Bubble' of warped Space-Time makes alarmingly consistent sense of the dead God's cyclopean city under the sea. From the paper: 'We calculate the type of matter which would be required to generate such exotic spacetime curvature. Unfortunately, we determine that the required matter is quite unphysical, and possess a nature which is entirely alien to all of the experiences of human science. Indeed, any civilization with mastery over such matter would be able to construct warp drives, cloaking devices, and other exotic geometries required to conveniently travel through the cosmos.'"

From the article: '“Hopefully, we can contribute to the training of this technology,” said Dr. James K. Stoller, chairman of the Education Institute at Cleveland Clinic. The goal, he added, was for Watson to become a “very smart assistant.” Part of Watson’s training will be to feed it test questions from the United States Medical Licensing Exam, which every human student must pass to become a practicing physician. The benefit for Watson should be to have a difficult but measurable set of questions on which to measure the progress of its machine-learning technology.'"

MTorrice writes "Researchers have demonstrated a way to make high performance, flexible integrated circuits using almost exclusively standard equipment and materials already needed to make conventional chips. Such a method could allow electronics manufacturers to build new devices, such as smart medical implants and flexible displays, without needing to significantly overhaul current production protocols. The method, developed by researchers at the University of Texas, Austin, started with researchers patterning integrated circuits on silicon wafers using a standard production line. They then cut off the top 20 to 30 micrometers of the wafer using a thin wire—like slicing a block of cheese—to produce a thin, flexible platter of circuits."

Empathy Represses Analytic Thought, and Vice Versa 293

from the take-note-sports-fans dept.
hessian sends this quote from a Case Western Reserve University news release: "New research shows a simple reason why even the most intelligent, complex brains can be taken by a swindler's story – one that upon a second look offers clues it was false. When the brain fires up the network of neurons that allows us to empathize, it suppresses the network used for analysis, a pivotal study led by a Case Western Reserve University researcher shows (abstract). ... At rest, our brains cycle between the social and analytical networks. But when presented with a task, healthy adults engage the appropriate neural pathway, the researchers found. The study shows for the first time that we have a built-in neural constraint on our ability to be both empathetic and analytic at the same time. The work suggests that established theories about two competing networks within the brain must be revised. More, it provides insights into the operation of a healthy mind versus those of the mentally ill or developmentally disabled."

A Beholder monster lurches at you, its eyeballs wriggling on tentacular stems. As you prepare to wield your Vorpal sword, where do you focus your gaze: at the monster's head or at its tentacle eyes? Such a quandary from the role-playing game Dungeons & Dragons may seem like a meaningless trifle, but it holds within it the answer to a tricky scientific question: Do people focus their gaze on another person's eyes or on the center of the head? In fact, a father-son team has used D&D monsters to show that most people will look to another creature's eyes, even if they're not attached to a head."
