Fuzzy theory. Perhaps this will help to explain our recent form, but l doubt it muchly.

MAggie simpson writes a science paper and has it published in a science journal, 2 infact. bout time.http://www.vox.com/2014/12/7/7339587/simpsons-science-paper
Of course, none of these fictional characters actually wrote the paper, titled "Fuzzy, Homogeneous Configurations." Rather, it's a nonsensical text, submitted by engineer Alex Smolyanitsky in an effort to expose a pair of scientific journals — the Journal of Computational Intelligence and Electronic Systems and the comic sans-loving Aperito Journal of NanoScience Technology.https://www.tumblr.com/search/Alex+Smolyanitsky
That should say "scientific “journals” " (and be pronounced with the big air quote signs)

Scientists unveil map of 'epigenome,' a second genetic codeBY SHARON BEGLEY
NEW YORK Wed Feb 18, 2015 7:06am EST(Reuters) - Scientists for the first time have mapped out the molecular “switches” that can turn on or silence individual genes in the DNA in more than 100 types of human cells, an accomplishment that reveals the complexity of genetic information and the challenges of interpreting it.
Researchers unveiled the map of the “epigenome” in the journal Nature on Wednesday, alongside nearly two dozen related papers. The mapping effort is being carried out under a 10-year, $240 million U.S. government research program, the Roadmap Epigenomics Program, which was launched in 2008.
The human genome is the blueprint for building an individual person. The epigenome can be thought of as the cross-outs and underlinings of that blueprint: if someone’s genome contains DNA associated with cancer but that DNA is “crossed out” by molecules in the epigenome, for instance, the DNA is unlikely to lead to cancer.
As sequencing individuals’ genomes to infer the risk of disease becomes more common, it will become all the more important to figure out how the epigenome is influencing that risk as well as other aspects of health. Sequencing genomes is the centerpiece of the “precision medicine” initiative that U.S. President Barack Obama announced this month.
“The only way you can deliver on the promise of precision medicine is by including the epigenome,” said Manolis Kellis of the Massachusetts Institute of Technology, who led the mapping that involved scientists in labs from Croatia to Canada and the United States.
Drug makers including Merck & Co Inc., the Genentech unit of Roche Holding and GlaxoSmithKline Plc are conducting epigenetics research related to cancer, said Joseph Costello of the University of California, San Francisco, director of one of four main labs that contributed data to the epigenome map.
Epigenetic differences are one reason identical twins, who have identical DNA, do not always develop the same genetic diseases, including cancer.
But incorporating the epigenome in precision medicine is daunting.
“A lifetime of environmental factors and lifestyle factors” influence the epigenome, including smoking, exercising, diet, exposure to toxic chemicals and even parental nurturing, Kellis said in an interview. Not only will scientists have to decipher how the epigenome affects genes, they will also have to determine how the lives people lead affect their epigenome.
BOOK OF LIFE
The human genome is the sequence of all the DNA on chromosomes. The DNA is identical in every cell, from neurons to hearts to skin.
It falls to the epigenome to differentiate the cells: as a result of epigenetic marks, heart muscle cells do not make brain chemicals, for instance, and neurons do not make muscle fibers.
The epigenome map published on Wednesday shows how each of 127 tissue and cell types differs from every other at the level of DNA. Because scientists involved in the Roadmap project have been depositing their findings in a public database as they went along, other researchers have been analyzing the information before the map was formally published.
One of the resulting studies show, for instance, that brain cells from people who died with Alzheimer’s disease had epigenetic changes in DNA involved in immune response. Alzheimer’s has never been seen as an immune-system disorder, so the discovery opens up another possible avenue to understand and treat it.
Other researchers found that because the epigenetic signature of different kinds of cells is unique, they could predict with nearly 90 percent accuracy where metastatic cancer originated, something that is unknown in 2 percent to 5 percent of patients.
As a result, epigenetic information might offer a life-saving clue for oncologists trying to determine treatment, said co-senior author Shamil Sunyaev, a research geneticist at Brigham and Women’s Hospital in Boston.
There is much more to come. Instead of the epigenome map being the end, said Kellis, “I very much see (it) as beginning a decade of epigenomics.”

Wow never knew about this hole. Maybe we could re-seal it after placing SWSNBN into it.
Aussie student proves existence of plasma tubes floating above Earth
AN AUSTRALIAN scientist has discovered that giant, invisible, moving plasma tubes fill the skies above Earth.
It’s a finding that was initially met with a considerable degree of scepticism within the field of astrophysics, but a University of Sydney undergraduate student Cleo Loi, 23, has proven that the phenomenon exists.By using a radio telescope in the West Australian outback to see space in 3D, Ms Loi has proven that the Earth’s atmosphere is embedded with these strangely shaped, tubular plasma structures. The complex, multilayered ducts are created by the atmosphere being ionised by sunlight.
“For over 60 years, scientists believed these structures existed, but by imaging them for the first time, we’ve provided visual evidence that they are really there,” said Ms Loi, of the Australia Research Council Centre of Excellence for All-sky Astrophysics (CAASTRO).
“We measured their position to be about 600km above the ground, in the upper ionosphere, and they appear to be continuing upwards into the plasmasphere."“This is around where the neutral atmosphere ends, and we are transitioning to the plasma of outer space."
“We saw a striking pattern in the sky where stripes of high-density plasma neatly alternated with stripes of low-density plasma. This pattern drifted slowly and aligned beautifully with the Earth’s magnetic field lines, like aurorae."
“We realised we may be onto something big.”
The breakthrough came when Ms Loi used the remote telescope, the Murchison Widefield Array (MWA), to map large patches of the sky in a new way.
By separating the signals from tiles in the east from the ones in the west, the astronomers gave the MWA — a set of 128 antenna tiles spread over 9sq km in the desert — the power to see in 3D.
“This is like turning the telescope into a pair of eyes, and by that we were able to probe the 3D nature of these structures and watch them move around,” Ms Loi said.
“We were able to measure the spacing between them, their height above the ground and their steep inclination. This has never been possible before and is a very exciting new technique.”
Ms Loi told news.com.au that her research was initially dismissed as being based on imperfections in the telescope images.
“They had never seen this type of thing before. No one had looked at the data in this way before,” she said.
“A lot of the people were pretty convinced is was some problem with the imaging, that it was nothing to get excited about.
“But, I guess being a student and being a bit stubborn, I was so curious, so mystified.
“I was careful about what had happened, and that’s how everyone came to be convinced that it had to be something else.
“We found that the ionisation patterns in the ionosphere are quite structured. They flow in these tubular structures that are aligned with the Earth’s magnetic field. And they can then move of their own accord.”
Ms Loi said the drifting plasma tubes could distort astronomical data, especially satellite-based navigation systems. It may also mean we need to re-evaluate our thinking about how galaxies, stars and clouds of gas behave and what they look like.
Ms Loi’s supervisor Tara Murphy said her work was impressive.
“It is to Cleo’s great credit that she not only discovered this but also convinced the rest of the scientific community. As an undergraduate student with no prior background in this, that is an impressive achievement,” said Dr Murphy, also of CAASTRO and the School of Physics at the University of Sydney.
“When they first saw the data, many of her senior collaborators thought the results were literally ‘too good to be true’ and that the observation process had somehow corrupted the findings, but over the next few months, Cleo managed to convince them that they were both real and scientifically interesting.”
Ms Loi’s research has been published in Geophysical Research Letters: http://onlinelibrary.wiley.com/doi/10.1002/2015GL063699/full
Yeah, but will it make petrol cheaper?
Yeah, but will it make petrol cheaper?
yes, but the savings will be eaten by plasma tube costs that big oil can’t afford not to pass on to customers.
Sounds a bit too arty. We don’t want actual bludgers sitting around soaking up government grants while we’re using that excuse on trained science professionals.
Four mysterious spots detected on PlutoFriday, 3 July 2015

Pluto strange spots(Source: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute )
A row of four mysterious dark spots have been discovered on the frozen surface of the distant world of Pluto by the NASA’s New Horizons spacecraft.
Scientists are at a loss to explain the intriguing spots which are remarkably consistent in both their even spacing along the dwarf planet’s equator, and their shape and size.
Each spot appears to be circular and about 480 kilometres in diameter.
“It’s a real puzzle-we don’t know what the spots are, and we can’t wait to find out,” says New Horizons principal investigator Dr Alan Stern of the Southwest Research Institute, Boulder, Colorado.
“Also puzzling is the longstanding and dramatic difference in the colours and appearance of Pluto compared to its darker and greyer moon, Charon.”
The strange spots were detected in new images of Pluto and its largest moon Charon, taken by New Horizons on June 25 and 27, 2015.
The new pictures, which combined black-and-white images of Pluto and Charon, shows Pluto has two remarkably different faces.
The image on the left shows the side of Pluto that will be seen at highest resolution when New Horizons makes its close approach on July 14.
The hemisphere is dominated by a very dark region extending along the equator, which appears near the bottom of the dwarf planet from New Horizon’s point of view.
The image on the right shows the hemisphere of Pluto that faces Charon, with the row of strange spots clearly visible along the equator.
While the origin of the spots is a mystery for now, the answer may be revealed as the spacecraft continues its approach to the Pluto system.
New Horizons has been given a final “all clear” as it speeds ever closer towards its historic once-in-a-lifetime close encounter with Pluto.
After a journey that has lasted more than nine years, the washing machine-sized spacecraft will make its closest approach to Pluto at 21:49:57 AEST, flying just 12,500 kilometres above the dwarf planet’s frozen surface.
