Study Finds Link Between Artificial Sweeteners and Glucose Intolerance 98

Posted by timothy
from the tastes-sweet-produce-insulin dept.
onproton (3434437) writes The journal Nature released a study today that reveals a link between the consumption of artificial sweeteners and the development of glucose intolerance [note: abstract online; paper itself is paywalled], a leading risk factor for the development of type 2 diabetes, citing a critical alteration of intestinal bacteria. Paradoxically, these non-caloric sweeteners, which can be up to 20,000 times sweeter than natural sugars, are often recommended to diabetes patients to control blood glucose levels. Sugar substitutes have come under additional fire lately from studies showing that eating artificially sweetened foods can lead to greater overall calorie consumption and even weight gain. While some, especially food industry officials, remain highly skeptical of such studies, more research still needs to be done to determine the actual risks these substances may pose to health.

coondoggie writes Lack of money, management structure and staff are hampering NASA's ability to effectively identify and track comets, meteorites and asteroids that might threaten Earth. The space agency's Inspector General, Paul Martin, issued a scathing report this week that said while NASA's Near Earth Object program has done substantial work in identifying the sometimes massive rocks hurtling around the planet it is substantially behind in its goal of cataloging 90% of those 140 meters in diameter by 2020, among other issues.

ULA and Jeff Bezos' Blue Origin Announce Rocket Engine Partnership 18

from the working-together dept.
An anonymous reader writes During an event at the National Press Club, Bezos announced an agreement with Blue Origin and United Launch Alliance, the joint venture of Boeing and Lockheed Martin, to continue development of a new rocket engine for ULA's Atlas and Delta rocket lines. From the article: "Called BE-4, the engine has been in the works at Blue Origin for three years and is currently in testing at the company's West Texas facilities. ULA, founded in 2006, has supplied rockets to the US Department of Defense and NASA and will now co-fund the BE-4 project to accelerate its completion. The agreement is for a four-year development process with testing slated for 2016 and flight in 2019."

Are Matt's Robot Hexapods Creepy or Cute? (Video) 34

University of Arizona grad student Matt Bunting doesn't come across as a mad scientist. That's a very good thing, because his robot hexapod creations are easy to imagine crawling across the USA in large hordes, devouring everything in their path and using all the electricity they come across to feed their Queen Hexapod, a 3-D printer mounted on a hexapod chassis that turns everything fed to it into more robots. Luckily, the real life Matt is an affable (self-described) "Roboticist, Electrical Engineer, Musician, and Rock Crawler" who freely admits that at this time his robotic creations have no practical application whatsoever. This is probably true, except for the fact that they can liven up a music video like mad, as you can see on YouTube in Pedals Music Video (featuring REAL robots) . Our little video is a lot simpler, of course. In it, we interview Matt and he tells us what he's up to with his robots, and gives some 'how to get started with robotics' advice for budding young engineers. (Alternate Video Link)

Obama Presses Leaders To Speed Ebola Response 199

from the wipe-it-out dept.
mdsolar writes with the latest plan from the U.S. government to fight the Ebola epidemic in West Africa, and a call for more help from other nations by the President. President Obama on Tuesday challenged world powers to accelerate the global response to the Ebola outbreak that is ravaging West Africa, warning that unless health care workers, medical equipment and treatment centers were swiftly deployed, the disease could take hundreds of thousands of lives. "This epidemic is going to get worse before it gets better," Mr. Obama said here at the Centers for Disease Control and Prevention, where he met with doctors who had just returned from West Africa. The world, he said, "has the responsibility to act, to step up and to do more. The United States intends to do more." Even as the president announced a major American deployment to Liberia and Senegal of medicine, equipment and 3,000 military personnel, global health officials said that time was running out and that they had weeks, not months, to act. They said that although the American contribution was on a scale large enough to make a difference, a coordinated assault in Africa from other Western powers was essential to bringing the virus under control.

ISIS Bans Math and Social Studies For Children 835

from the control-through-indoctrination dept.
mpicpp sends this news from CNN: In swaths of Syria now controlled by ISIS, children can no longer study math or social studies. Sports are out of the question. And students will be banned from learning about elections and democracy. Instead, they'll be subjected to the teachings of the radical Islamist group. And any teacher who dares to break the rules "will be punished." ISIS revealed its new educational demands in fliers posted on billboards and on street poles. The Sunni militant group has captured a slew of Syrian and Iraqi cities in recent months as it tries to establish a caliphate, or Islamic state, spanning Sunni parts of both countries. Books cannot include any reference to evolution. And teachers must say that the laws of physics and chemistry "are due to Allah's rules and laws."

Farmers Carry Multidrug-Resistant Staph For Weeks Into Local Communities 113

from the part-of-the-farmhand-insurrection dept.
An anonymous reader writes: Fresh research out of the UNC Gillings and JHU Bloomberg schools of public health shows industrial farm workers are carrying livestock-associated, multidrug-resistant staph into local communities for weeks at a time. "Among the [22 people tested], 10 workers carried antibiotic-resistant strains of the bacteria in their noses for up to four days. Another six workers were intermittent carriers of the bacteria. The 10 workers found to carry the bacteria persistently had strains associated with livestock that were resistant to multiple drugs, and one also carried MRSA. Three more of the workers tested positive for strains of S. aureus that were not resistant to antibiotics. So in total, 86 percent of the workers in the study carried the S. aureus bacteria, compared with about one-third of the population at large, according to the Centers for Disease Control and Prevention." This problem has grown since its last mention on Slashdot. Unfortunately, massive industrial lobbying continues to neuter government action.

NASA's Manned Rocket Contract: $4.2 Billion To Boeing, $2.6 Billion To SpaceX 181

Posted by Soulskill
from the go-big-or-go-home dept.
schwit1 writes NASA has chosen two companies to ferry astronauts to and from the International Space Station, and those companies are Boeing and SpaceX. This decision confirms that SpaceX is ready to go and gives the company the opportunity to finish the job, while also giving Boeing the chance to show that it can still compete. After NASA has certified that each company has successfully built its spacecraft, SpaceX and Boeing will each fly two to six missions. The certification process will be step-by-step, similar to the methods used in the cargo contracts, and will involve five milestones. The contracts will be paid incrementally as they meet these milestones. One milestone will be a manned flight to the ISS, with one NASA astronaut on board. Boeing will receive $4.2 billion, while SpaceX will get $2.6 billion. These awards were based on what the companies proposed and requested.

Astronomers Find Star-Within-a-Star, 40 Years After First Theorized 71

Posted by Soulskill

derekmead writes: After 40 years, astronomers have likely found a rather strange celestial body known as a Thorne–Zytkow object (TZO), in which a neutron star is absorbed by a red supergiant. Originally predicted in the 1970s, the first non-theoretical TZO was found earlier this year, based on calculations presented in a paper forthcoming in MNRAS.

TZOs were predicted by astronomer Kip Thorne and Anna Zytkow, who wasthen postdoctoral fellow at CalTech. The pair imagined what might happen if a neutron star in a binary system merged with its partner red supergiant. This wouldn't be like two average stars merging. Neutron stars are the ancient remnants of stars that grew too big and exploded. Their cores remain small — about 12.5 miles across — as they shed material out into space. Red supergiants are the largest stars in the galaxy, with radii up to 800 times that of our sun, but they aren't dense.

WSJ Reports Boeing To Beat SpaceX For Manned Taxi To ISS 195

PvtVoid writes The Wall Street Journal reports (paywalled) that NASA is poised to award a key contract for manned transport to the International Space Station to Boeing over rival SpaceX: "Recent signals from the Obama administration, according to the officials, indicate that the National Aeronautics and Space Administration's leadership has concluded on a preliminary basis that Boeing's proposed capsule offers the least risky option, as well as the one most likely to be ready to transport U.S. crews to the international space station within three years. The officials cautioned that a last-minute shift by NASA chief Charles Bolden, who must vet the decision, could change the result of the closely watched competition."

Schizophrenia Is Not a Single Disease 213

Posted by Soulskill
from the inconsistency-explained dept.
An anonymous reader writes: New research from Washington University has found that the condition known as schizophrenia is not just a single disease, but instead a collection of eight different disorders. For years, researchers struggled to understand the genetic basis of schizophrenia. This new method was able to isolate and identify the different conditions (each with its own symptoms) currently classified under the same heading (abstract, full text). "In some patients with hallucinations or delusions, for example, the researchers matched distinct genetic features to patients' symptoms, demonstrating that specific genetic variations interacted to create a 95 percent certainty of schizophrenia. In another group, they found that disorganized speech and behavior were specifically associated with a set of DNA variations that carried a 100 percent risk of schizophrenia." According to one of the study's authors, "By identifying groups of genetic variations and matching them to symptoms in individual patients, it soon may be possible to target treatments to specific pathways that cause problems."

Sci-Fi Authors and Scientists Predict an Optimistic Future 189

Posted by Soulskill
from the roddenberry-approved dept.
An anonymous reader writes: A few years ago, author Neal Stephenson argued that sci-fi had forgotten how to inspire people to do great things. Indeed, much of recent science fiction has been pessimistic and skeptical, focusing on all the ways our inventions could go wrong, and how hostile the universe is to humankind. Now, a group of scientists, engineers, and authors (including Stephenson himself) is trying to change that. Arizona State University recently launched Project Hieroglyph, a hub for ideas that will influence science fiction to be more optimistic and accurate, and to focus on the great things humanity is capable of doing.

For example, in the development of a short story, Stephenson wanted to know if it's possible to build a tower that's 20 kilometers tall. Keith Hjelmsad, an expert in structural stability and computational mechanics, wrote a detailed response about the challenge involved in building such a tower. Other authors are contributing questions as well, and researchers are chiming in with fascinating, science-based replies. Roboticist Srikanth Saripalli makes this interesting point: "If the government has to decide what to fund and what not to fund, they are going to get their ideas and decisions mostly from science fiction rather than what's being published in technical papers."

Artificial Spleen Removes Ebola, HIV Viruses and Toxins From Blood Using Magnets 105

Posted by samzenpus
from the cleaning-the-system dept.
concertina226 writes Harvard scientists have invented a new artificial spleen that is able to clear toxins, fungi and deadly pathogens such as Ebola from human blood, which could potentially save millions of lives. When antibiotics are used to kill them, dying viruses release toxins in the blood that begin to multiply quickly, causing sepsis, a life-threatening condition whereby the immune system overreacts, causing blood clotting, organ damage and inflammation. To overcome this, researchers have invented a "biospleen", a device similar to a dialysis machine that makes use of magnetic nanobeads measuring 128 nanometres in diameter (one-five hundredths the width of a single human hair) coated with mannose-binding lectin (MBL), a type of genetically engineered human blood protein.

Extent of Antarctic Sea Ice Reaches Record Levels 599

schwit1 writes Scientists have declared a new record has been set for the extent of Antarctic sea ice since records began. Satellite imagery reveals an area of about 20 million square kilometers covered by sea ice around the Antarctic continent. Jan Lieser from the Antarctic Climate and Ecosystems Cooperative Research Centre (CRC) said the discovery was made two days ago. "Thirty-five years ago the first satellites went up which were reliably telling us what area, two dimensional area, of sea ice was covered and we've never seen that before, that much area."

European Space Agency Picks Site For First Comet Landing In November 35

Posted by samzenpus
from the x-marks-the-spot dept.
An anonymous reader writes Europe's Rosetta mission, which aims to land on a comet later this year, has identified what it thinks is the safest place to touch down. From the article: "Scientists and engineers have spent weeks studying the 4km-wide "ice mountain" known as 67P, looking for a location they can place a small robot. They have chosen what they hope is a relatively smooth region on the smaller of the comet's two lobes. But the team is under no illusions as to how difficult the task will be. Comet 67P/Churyumov-Gerasimenko, currently sweeping through space some 440 million km from Earth, is highly irregular in shape. Its surface terrain is marked by deep depressions and towering cliffs. Even the apparently flat surfaces contain potentially hazardous boulders and fractures. Avoiding all of these dangers will require a good slice of luck as well as careful planning.

First time accepted submitter rinka writes India's Mars Orbiter Mission, known as Mangalyaan, has made some progress since we last discussed it. The mission is on target and has completed 95% of its journey. It will reach its destination before the end of the month. Scientists will undertake a "challenging task" on September 24 when they will restart the onboard liquid engine, which has been in sleep mode for nearly ten months, for a critical maneuver of the spacecraft.

If We Can't Kill Cancer, Can We Control It? 140

An anonymous reader sends this excerpt from The New Yorker: In April, [Dr. Eytan Stein] presented his findings to a packed auditorium at the annual meeting of the American Association for Cancer Research, in San Diego. It was the first public airing of the results of AG-221; patients with progressive [acute myelogenous leukemia] had never improved so quickly and definitively. ... The breakthrough is notable in part for the unconventional manner in which the drug attacks its target. There are many kinds of cancer, but treatments have typically combated them in one way only: by attempting to destroy the cancerous cells. Surgery aims to remove the entire growth from the body; chemotherapy drugs are toxic to the cancer cells; radiation generates toxic molecules that break up the cancer cells' DNA and proteins, causing their demise. A more recent approach, immunotherapy, co-opts the body's immune system into attacking and eradicating the tumor. The Agios drug, instead of killing the leukemic cells — immature blood cells gone haywire — coaxes them into maturing into functioning blood cells. Cancerous cells traditionally have been viewed as a lost cause, fit only for destruction. The emerging research on A.M.L. suggests that at least some cancer cells might be redeemable: they still carry their original programming and can be pressed back onto a pathway to health.

Why Atheists Need Captain Kirk 887

from the need-a-way-to-cheat-death dept.
New submitter anlashok writes: Atheism and science face a real challenge: To frame an account of science, or nature, that leaves room for meaning. According to this article, atheists have pinned their flag to Mr. Spock's mast. But they need Captain Kirk. Quoting: "I'm pro-science, but I'm against what I'll call "Spock-ism," after the character from the TV show Star Trek. I reject the idea that science is logical, purely rational, that it is detached and value-free, and that it is, for all these reasons, morally superior. Spock-ism gives us a false picture of science. It gives us a false picture of humankind's situation. We are not disinterested knowers. The natural world is not a puzzle. ... The big challenge for atheism is not God; it is that of providing an alternative to Spock-ism. We need an account of our place in the world that leaves room for value."

US Scientists Predict Long Battle Against Ebola 119

from the time-to-call-in-dustin-hoffman-and-rene-russo dept.
An anonymous reader writes: Despite recent advances in medicine to treat Ebola, epidemiologists are not hopeful that the outbreak in west Africa will be contained any time soon. Revised models for the disease's spread expect the outbreak to last 12 to 18 months longer, likely infecting hundreds of thousands of people. "While previous outbreaks have been largely confined to rural areas, the current epidemic, the largest ever, has reached densely populated, impoverished cities — including Monrovia, the capital of Liberia — gravely complicating efforts to control the spread of the disease. ... What worries public health officials most is that the epidemic has begun to grow exponentially in Liberia. In the most recent week reported, Liberia had nearly 400 new cases, almost double the number reported the week before. Another grave concern, the W.H.O. said, is 'evidence of substantial underreporting of cases and deaths.' The organization reported on Friday that the number of Ebola cases as of Sept. 7 was 4,366, including 2,218 deaths." Scientists are urging greater public health efforts to slow the exponential trajectory of the disease and bring it back under control.
