I occasionally get questions about usage of Science 2.0 that go beyond the FAQ so I decided I would write up a short article on using the site for non-beginners. The FAQ covers the basics - what Science 2.0® is, the experimental nature of this open writing site for science, etc. along with the basic functionality, like the dashboard - but due to the way the site has grown some other features may not be evident for newer members.
How to find good stuff to write about?
On September 16th the 2010 World Solar-Powered Air Conditioning Development Forum was held in Dezhou, a municipality of China's Shandong Province.
What is really happening in apparently empty areas of the Galaxy? It may get a rethink because scientists have managed to find a molecule that has an unexpectedly complicated structure in interstellar clouds of extremely small density.
Translucent interstellar clouds are penetrated by highly energetic ultraviolet and cosmic radiation which should break any chemical species it meets but a group of scientists have managed to observe in those clouds a molecule made up of an unexpectedly large number of atoms: the diacetylene cation; a discovery which may contribute to solving the oldest unsolved puzzle of spectroscopy.
The density of translucent interstellar clouds is extremely small.
Tolerance has meant different things in different eras. For some religions in the past, there was a 'convert or die' mentality, which tended to drive out competitors but, at least when it comes to works of art, old religions have always survived.
A fresco of Tyche, the Greek goddess of fortune from the Byzantine period had been discovered at the Sussita site, on the east shore of the Sea of Galilee, and a maenad, one of the companions of the wine god Dionysus, was found also. The city of Sussita is located within the Sussita National Park under the management of the Israel Nature and Parks Authority.
Human vision is very advanced. While a human child can look at a cartoon picture of a chicken and know that's a chicken, computers cannot. We can also recognize cars, people, trees and lampposts instantaneously on a busy street without much thought and decide what to do.
That's an enormous number of computations and just one reason that coming up with a computer-driven system that can mimic the human brain in visually recognizing objects has been difficult. Eugenio Culurciello of Yale's School of Engineering&Applied Science has developed a machine dubbed Neuflow, which is 'based' on the human visual system and operates much more quickly and efficiently than predecessors, coming closer to the mammalian visual system.
Premature ovarian failure (POF) is when a woman's ovaries stop working before she is 40. Missed periods are usually the first sign of POF. Later symptoms may be similar to those of natural menopause.
Most women with POF cannot get pregnant naturally. Fertility treatments help a few women; others use donor eggs to have children. There is no treatment that will restore normal ovarian function, though many health care providers suggest taking hormones until age 50. According to the
International Premature Ovarian Failure Association, between 1 and 4% of women suffer from POF – equivalent to between 250,000 and 1 million women in the USA alone.
There was a time a few years ago when the music industry was in the doldrums. They blamed MP3 piracy, though it made no sense unless you were the kind of person who believes 'jobs saved or created' is also a valid metric for beneficial impact of government stimulus plans - basically, claiming that every pirated piece of music was a lost sale was unrealistically hopeful. Most pirates may download something, but they weren't going to buy it anyway.
Yet capitalism began to reshape the music industry even when they couldn't figure out how themselves. iTunes made it elegant for people to buy songs, and so they did, and now capitalism is at work in the music itself.
Multidisciplinary collaborative research teams are essential in modern day science - climate scientists need to make more accurate numerical models and genome data in biology can be overwhelming and that means working with experts in other fields – but working as part of a team with experts outside a researcher's discipline can create its own problems so a group of researchers has published a commentary outlining a new field of study that could help resolve problems facing interdisciplinary research teams.
The new area of study, which they called the "science of team science," or SciTS (rhymes with sights), would focus on what works and what doesn't when teams of scientists are working together to accomplish an overarching research goal.
Micro air vehicles (MAVs) under development by the Air Force Office of Scientific Research are on track to evolve into robotic, insect-scale devices for monitoring and exploration of hazardous environments, like collapsed structures, caves and chemical spills.
Researchers say they have found 13 genes linked to human body mass.
Starting with DNA samples extracted from Icelanders' white blood cells banked in 1991 and 2002 by scientists there as part of the AGES–Reykjavik study of individuals in the general population, scientists used a customized, genome-wide profiling method dubbed CHARM (comprehensive high-throughput arrays for relative methylation) to look for regions that were the most variable, all chemically marked by DNA methylation.
The DNA methylation analyses revealed epigenetic fingerprints which are unique to each individual and remain stable over time and may also be associated with various common traits including risks for common, complex diseases such as cancer and other conditions.
