Stanford Bioengineers Introduce 'Bi-Fi' - The Biological Internet | School of Engineering - 0 views

  •  
    "If you were a bacterium, the virus M13 might seem innocuous enough. It insinuates more than it invades, setting up shop like a freeloading houseguest, not a killer. Once inside it makes itself at home, eating your food, texting indiscriminately. Recently, however, bioengineers at Stanford have given M13 a bit of a makeover. The researchers, Monica Ortiz, a doctoral candidate in bioengineering, and Drew Endy, PhD, an assistant professor of bioengineering, have parasitized the parasite and harnessed M13's key attributes - its non-lethality and its ability to package and broadcast arbitrary DNA strands - to create what might be termed the biological Internet, or "Bi-Fi." Their findings were published online Sept. 7 in the Journal of Biological Engineering."

Patricia Springfield: Technology and Informal Education: What Is Taught, What Is Learned - 0 views

  •  
    "Formal education must adapt to these changes, taking advantage of new strengths in visual-spatial intelligence and compensating for new weaknesses in higher-order cognitive processes: abstract vocabulary, mindfulness, reflection, inductive problem solving, critical thinking, and imagination. These develop through the use of an older technology, reading, which, along with audio media such as radio, also stimulates imagination. Informal education therefore requires a balanced media diet using each technology's specific strengths in order to develop a complete profile of cognitive skills. "

Dan Kahan: Science Confirms: Politics Wrecks Your Ability to Do Math - 0 views

  •  
    "For study author Dan Kahan, these results are a fairly strong refutation of what is called the "deficit model" in the field of science and technology studies-the idea that if people just had more knowledge, or more reasoning ability, then they would be better able to come to consensus with scientists and experts on issues like climate change, evolution, the safety of vaccines, and pretty much anything else involving science or data (for instance, whether concealed weapons bans work). Kahan's data suggest the opposite-that political biases skew our reasoning abilities, and this problem seems to be worse for people with advanced capacities like scientific literacy and numeracy"

@PeterSpork #epigenetik #sleep BBC News - How much can an extra hour's sleep change you? - 0 views

  •  
    Dr Simon Archer and his team at Surrey University were particularly interested in looking at the genes that were switched on or off in our volunteers by changes in the amount that we had made them sleep. "We found that overall there were around 500 genes that were affected," Archer explained. "Some which were going up, and some which were going down." What they discovered is that when the volunteers cut back from seven-and-a-half to six-and-a-half hours' sleep a night, genes that are associated with processes like inflammation, immune response and response to stress became more active. The team also saw increases in the activity of genes associated with diabetes and risk of cancer. The reverse happened when the volunteers added an hour of sleep. So the clear message from this experiment was that if you are getting less than seven hours' sleep a night and can alter your sleep habits, even just a little bit, it could make you healthier

@5eenGeno What is wrong with our bees? - Victorian Apiarists' Association (VAA) - 0 views

  •  
    "Everybody likes a simple cause and effect - something we can point to and say (ommitting a few choice words to the perpetrators), 'Fix this and the bees will be right again.' Reality is rarely so straightforward. As the bee decline has progressed I've lost count of the simple 'causes' that have been presented. Among the more memorable are: * mobile 'phones (the absolute 'definite cause' of choice a couple of years ago) * mobile base stations, power lines and other strong electromagnetic sources (a perennial favourite for any malaise) * alien abduction (hopefully they have smaller probes for abducted bees...) * God's punishment (pro gay-marriage states in the USA have more cases of CCD) Leo's article shows neonicotinoids are at least a plausible candidate and they are surely not good for bees, but the argument for these being the explicit 'cause' of global bee decline is still not particularly strong. The risk here is that the media and vocal lobbyists are going off on a righteous crusade to the detriment of more diligent, and maybe less newsworthy, efforts to get to the root of a complex problem. Rather than reviewing the evidence here, I recommend a visit to Randy Oliver's website where his two recent articles from the American Bee Journalon this topic can be found, along with some further commentary on his home page. Interested readers can also directly access the study by Henry et. al. (2012a), the commentry on this study by Creswell and Thompson (2012), the response to the comment (Henry et. al. 2012b) and to the meta-analysis of toxicological studies on imidacloprid by Creswell (2010). An example of one such study is Cutler and Scott-Dupree (2007). Links to all are included below. These are original material rather than reportage and demonstrate the complexity of the issue. As food for thought, I'll leave you with the following: * Neonicotinoids are widely used in Australia and our bees are not (yet) in decline."

How to break into science writing using your blog and social media (#sci4hels) | The SA... - 0 views

  •  
    "It is important to be aware that 20th century media ecosystem is a very unusual aberration in the way people communicated throughout history. Means of production were expensive. Very few people could afford to own printing presses, radio and TV studios, etc. Running all that complicated equipment required technical expertise and professional training. Thus media became locked up in silos, hierarchical, broadcast-only with little-to-none (and then again centrally controlled) means for feedback. There was a wealthy, vocal minority that determined what was news, and how to frame it, and the vast majority was consuming the news in silence"

Is there an ape for that? Orangutans plan trips - Salon.com - 0 views

  •  
    What he and his orangutan buddies do in the forests of Sumatra tells scientists that advance trip planning and social networking aren't just human traits, A new study of 15 wild male orangutans finds that they routinely plot out their next day treks and share their plans in long calls, so females can come by or track them, and competitive males can steer clear.

Archaeologists discover largest, oldest wine cellar in Near East - 0 views

  •  
    3,700 year-old store room held 2,000 liters of strong, sweet wine. Archaeologists have unearthed what may be the oldest -- and largest -- ancient wine cellar in the Near East, containing forty jars, each of which would have held fifty liters of strong, sweet wine. The cellar was discovered in the ruined palace of a sprawling Canaanite city in northern Israel, called Tel Kabri. The site dates to about 1,700 B.C. and isn't far from many of Israel's modern-day wineries.

Skull suggests three early human species were one - 0 views

  •  
    One of the most complete early human skulls yet found suggests that what scientists thought were three hominin species may in fact be one. This controversial claim comes from a comparison between the anatomical features of a 1.8-million-year-old fossil skull with those of four other skulls from the same excavation site at Dmanisi, Georgia. The wide variability in their features suggests that Homo habilis, Homo rudolfensis and Homo erectus, the species so far identified as existing worldwide in that era, might represent a single species.

How the brain recognizes objects - 0 views

  •  
    "Researchers at MIT's McGovern Institute for Brain Research have developed a new mathematical model to describe how the human brain visually identifies objects. The model accurately predicts human performance on certain visual-perception tasks, which suggests that it's a good indication of what actually happens in the brain, and it could also help improve computer object-recognition systems."
