Symbiotic Stars - 0 views

  •  
    Many, perhaps even most stars, are members of binaries -- two stars that orbit each other. Symbiotic stars are a small subset of binaries with an attitude: they display characteristic, dramatic, episodic changes in the spectra of their light because (it is thought) one star of pair is a very hot, small star while the other is a cool giant.

Collective intelligence in small teams | KurzweilAI - 0 views

  •  
    A new study co-authored by MIT researchers documents the existence of collective intelligence among groups of people who cooperate well, showing that such intelligence extends beyond the cognitive abilities of the groups' individual members, and that the tendency to cooperate effectively is linked to the number of women in a group.

Mikroplastik - ein unsichtbarer Störenfried - Holm - 2013 - Biologie in unser... - 0 views

    "Plastic is produced in large amounts and used for various purposes. After use, huge amounts end up in the enviroment, often in the oceans. There, fragmentation leads to small particles, called microplastics. By filtrating and benthos-feeding organisms it can be inadvertently taken up as food. We demonstrate that the unicellular ciliate Paramecium, the freshwater flea Daphnia and the blue mussel Mytilus took up microplastic particles. Even more, in Mytilus, the plastic particles were transported into the digestive gland and accumulated in the respective cells. Subsequently, pathological alterations in the gland were noted. Microplastics are of concern because animals might starve with a full belly after uptaking large amounts of microplastics. As well, particles with sharp edges can injure the mucous layer of the gastrointestinal tract. Furthermore, persistent organic pollutants adhere at plastic and thus, may cause adverse impacts on the animal. We show options for solutions and indicate selected organisations working on the development of solution"

In Flies' Innards, Vital Clues to Biodiversity - NYTimes.com - 0 views

  •  
    "How many mammal species live in the forest? It sounds like a simple question, but the actual distributions of shy, small or rare mammals are often murky, confounding conservationists seeking to protect them. Yet a paper published online on Tuesday in the journal Molecular Ecology explores a new way to track biodiversity: by capturing flies that feed on carcasses. The flies' stomachs offer DNA diaries of their recent meals, giving scientists clues to which animals live and die in the forest. "The animals are there, but you just don't see them," said Fabian Leendertz, a wildlife epidemiologist at the Robert Koch Institute in Berlin and an author of the paper. "Those flies will find them and will tell us what is there"

Ben Young Landis How Twitter Amplifies Your Reach: Example from the "School o... - 0 views

    "My link was shared by Bora Zivkovic, whose network is immense. And in turn, the link was shared by Twitter users in Greece, Germany, Belgium and throughout the United States. In the end, the blogpost wound up with 109 readers on January 22nd - with about 50 via Twitter, 26 via Facebook, and others via LinkedIn and elsewhere. When each person shared the link with her or his network, the momentum is carried forward, pushing out to new networks and new degrees of separation. Social sharing is a bit like the emails you would get forwarded by your relatives (you know, those emails). The deeper you scroll down the thread, the less sender names you recognize. But with Twitter, and using analytics like WordPress or Google, you can actually trace how a little link travels through different social networks, and eventually back to your website. Also, because many people embed a small bio or website link in their Twitter profile, I can quickly see who has retweeted and read my link. I can read their tweets to get an idea of their profession and passions,"

Do-it-yourself biotech: Ellen Jorgensen at TEDGlobal 2012 - 0 views

  •  
    "t turns out that all over the world there were people trying to do similar things - opening biohacker spaces. Three years later, this is a thriving global community. Each lab has a flavor of where it was created - people work together or alone, in big cities or small villages, they build things and take them apart, and do much, much more. The spirit is open. But what about the dark side? What about biosafety, biosecurity? The minute Genspace opened their doors, journalists called. And the only question they wanted to ask was, "Would this lab create the next Frankenstein?" The press was overestimating their capabilities - and underestimating their ethic"

    "In this study, we compared the ability of undergraduate students and guppies to discriminate the same numerical ratios, both within and beyond the small number range. In both students and fish the performance was ratio-independent for the numbers 1-4, while it steadily increased with numerical distance when larger numbers were presented."

Noise and Signal - Nassim Taleb | Farnam Street - 0 views

    "There is a biological story with information. I have been repeating that in a natural environment, a stressor is information. So too much information would be too much stress, exceeding the threshold of antifragility. In medicine, we are discovering the healing powers of fasting, as the avoidance of too much hormonal rushes that come with the ingestion of food. Hormones convey information to the different parts of our system and too much of it confuses our biology. Here again, as with the story of the news received at too high a frequency, too much information becomes harmful. And in Chapter x (on ethics) I will show how too much data (particularly when sterile) causes statistics to be completely meaningless. Now let's add the psychological to this: we are not made to understand the point, so we overreact emotionally to noise. The best solution is to only look at very large changes in data or conditions, never small ones"

Gut Microbes May Foster Heart Disease | Wired Science | Wired.com - 0 views

  •  
    ""We probably have underestimated the role our microbial flora play in modulating disease risk," says Daniel Rader, a heart disease specialist at the University of Pennsylvania School of Medicine. Rader, who was not involved in the study, says that gut bacteria may not be as big a factor in causing heart disease as diabetes or smoking, but could be important in tipping some people toward sickness. Researchers led by Stanley Hazen, a cardiologist at the Cleveland Clinic, didn't start out to study gut bacteria. In fact, says Hazen, he had "no clue - zero," that intestinal microbes were involved in heart disease. "I'd never even considered it or thought of the concept." Hazen and his colleagues compared blood plasma from healthy people to plasma from people who had had heart attacks, strokes or died to see if substances in the blood could predict who is in danger from heart disease. The researchers found 18 small molecules associated with fat buildup in the arteries. One of the best predictors turned out to be a byproduct made when gut bacteria break down a fat called choline (also known as lecithin). The more of this byproduct, called trimethylamine N-oxide or TMAO, a person or mouse has in the blood, the higher the risk of getting heart disease, the researchers found. Gut bacteria are actually middlemen in TMAO production. The microbes convert lecithin to a gas that smells like rotten fish. Then an enzyme in the liver changes the foul-smelling gas to TMAO."

    "Since cancers have individual clonal karyotypes, are immortal and evolve from normal cells treated by carcinogens only after exceedingly long latencies of many months to decades-we deduce that carcinogenesis may be a form of speciation. This theory proposes that carcinogens initiate carcinogenesis by causing aneuploidy, i.e., losses or gains of chromosomes. Aneuploidy destabilizes the karyotype, because it unbalances thousands of collaborating genes including those that synthesize, segregate and repair chromosomes. Driven by this inherent instability aneuploid cells evolve ever-more random karyotypes automatically. Most of these perish, but a very small minority acquires reproductive autonomy-the primary characteristic of cancer cells and species"

Spiegelman: Scientists find molecular link to obesity/insulin resistance in mice - 0 views

  •  
    "For this study, the investigators bred mice lacking TRPV4 or administered a drug to deactivate it. In the absence of TRPV4, white cells turned on a set of genes that consume energy to produce heat, rather than storing the energy as excess fat. This "thermogenic" process normally occurs in brown or beige fat (commonly called "good fat"), which is found mostly in small animals and human infants to protect against cold. When the TRPV4-deficient mice were put on a high-calorie diet for several weeks, they did not become obese, and their level of fat cell inflammation and insulin resistance was lowered. "We have identified a target that, when inhibited, can activate beige adipose tissue and suppress inflammation," said Spiegelman."

@biogarage Marcelo Coelo, Skylar Tibbits: MIT researchers unveil a smarter way to 3-D p... - 0 views

  •  
    "MIT-based researchers and instructors Marcelo Coelho and Skylar Tibbits teamed up to tackle this very problem. Working under a grant from Ars Electronica, the pair conceived of a whole new way to do 3-D printing. Hyperform is a new strategy for designing and printing large objects irrespective of a printer's bed size. So not only can you print out that chair at home, you can also print a table, bed frame, and everything else you need to furnish a bedroom. The solution is breathtakingly simple. By merely folding the object you want to print, you can jig it to fit into a small-scale printer. In Tibbits and Coelho's project, the object is rendered in 1-D--a line--and endlessly folded into a space-filling curve proportioned to the printer's cubic dimensions. (The designers partnered with Formlabs and iterated the process using a Form 1 tabletop printer.) When the object is exhumed from the printer bed, it doesn't at all resemble its final shape. Rather, it's a dense cluster of thin but sturdy polymer links packaged in a three-dimensional puzzle that can be intuitively assembled"

  •  
    "Researchers say they want to emphasize, however, that the HPV vaccine commonly used by millions of women around the world is perfectly safe if done prior to infection with the virus. The concerns raised by this study relate only to viral therapies or possible use of a therapeutic vaccine after the virus has already been integrated into human cells. "It's been known for decades that only women with prior infection with HPV get cervical cancer," said Andrey Morgun, an assistant professor and a leader of the study in the OSU College of Pharmacy. "In about 90 percent of cases it's naturally eliminated, often without any symptoms. But in a small fraction of cases it can eventually lead to cancer, in ways that have not been fully understood.""
