A ground-breaking new paper has recently been published in Earth System Dynamics that really turns the idea of direct linear warming of the atmosphere on it's ear, suggesting a "store and release mechanism" by the oceans, which explains why there seemed to be a shift in global temperature during the 1997/98 super El Nino followed by a "pause" in global temperatures.

Remember the "escalator" graph from wrongly named "Skeptical Science" designed to shame climate skeptics? Looks like that may have been an accidentally prescient backfire on their part based on the findings of this new paper.

The paper is: "Reconciling the signal and noise of atmospheric warming on decadal timescales", Roger N. Jones and James H. Ricketts, Earth System Dynamics, 8 (1), 2017.

Unexplained explosion coming from a galaxy 10.7 billion light-years away

 Universe
Scientists have taken the deepest X-ray image of our Universe to date - and within it, they've found evidence of a huge, unexplained explosion coming from a galaxy around 10.7 billion light-years away.

The galaxy itself appears to be fairly faint and unremarkable, but in October 2014, it suddenly became at least 1,000 times brighter over a few hours, before fading into oblivion again. No astronomical phenomenon that scientists currently know of can explain the behaviour.

"We may have observed a completely new type of cataclysmic event," said one of the researchers Kevin Schawinski, from ETH Zurich in Switzerland.

NASA has released images of Jupiter taken from the Juno probe during its fifth orbit of the planet. Amateur astronomers have processed the raw images into stunning full-color photographs.

Juno completed its latest orbit on March 27, and sent new images back to Earth using the JunoCam.

The $1 billion spacecraft launched in 2011 and took five years to reach Jupiter and begin orbiting the planet.

Activated by cold, the small amounts of brown fat scattered around your body can burn calories to warm you up. They also can help to lower insulin resistance and other conditions implicated in type 2 diabetes and obesity. Since the discovery in 2009 that brown fat can be active in adult humans, researchers around the world have worked to unveil ways to switch on this fat. Scientists at Joslin Diabetes Center now have identified a new route to throw the switch.

The investigators have shown that a lipid (a fat-like substance) called 12,13-diHOME that circulates in the blood signals brown fat cells in mice to fuel up with other lipids, says Matthew Lynes, a Joslin postdoctoral researcher and lead author on a paper describing the work in the journal Nature Medicine. In one experiment, obese mice given low levels of the molecule produced reduced levels of blood triglycerides—other forms of lipids that can increase risks for heart disease and diabetes in humans.

Richard Smith said reviews are slow, expensive and may not actually work.
The peer review process - long considered the gold standard of quality scientific research - is a "sacred cow" that should be slaughtered, the former editor of one of the country's leading medical journals has said.

Richard Smith, who edited the British Medical Journal for more than a decade, said there was no evidence that peer review was a good method of detecting errors and claimed that "most of what is published in journals is just plain wrong or nonsense".

Research papers considered for scientific and medical journals undergo a process of scrutiny by experts before they can be published. Hundreds of thousands of new studies are published around the world every year, and the peer review process exists to ensure that readers can have confidence that published findings are scientifically sound.

German scientists power up the world's largest artificial sun

artificial sun
Synlight is the largest collection of film projector spotlights ever assembled in one room, and scientists in Germany are turning them all on at once in the pursuit of efficient and renewable energy.

This experiment involving the world's "largest artificial sun" is taking place in Jülich, a town located 30 kilometers (19 miles) west of Cologne, and it was designed by scientists from the German Aerospace Center (DLR). The device features 149 industrial-grade film projector spotlights, and each one boasts roughly 4,000 times the wattage of the average light bulb.

When this artificial sun is turned on, it generates light that's 10,000 times as intense as natural sunlight on Earth. Swiveling the lamps and concentrating them on one spot can produce temperatures of around 3,500 degrees Celsius (6,332 degrees Fahrenheit), which is three times as hot as the heat generated by a blast furnace.

IFace 3.0 Mobile: Tech company develops selfie logins

selfie log in
Many times we come across tech press releases that are little more than grabs for funding within a climate of ripe pickings for anyone involved with security development. Often outlandish and impractical, a good deal of them can be dismissed quickly. However, the trend toward more pervasive biometrics cannot be denied. It is showing up at banks, in police work, border control, travel of all kinds, and even on your home computer.

This press release posted at One World Identity from Innovatrics - a company that boasts "900 million people having been biometrically processed using Innovatrics software" - appears to be a serious player in the field. Utilizing a cute tagline of "popularizing the 'selfie login'" this press release shows that it is far more than a personal security choice. We are already seeing that federal biometric databases have been established in secret, yet the technology continues to expand even as the ethical boundaries remain unestablished.

My emphasis added.

Anti-aging pill slows aging

Can a pill make you younger?

One of the few drug studies ever carried out in an attempt to address this question was reported by Novartis on Christmas Eve 2014. The company had sought to see whether giving low doses of a drug called everolimus to people over 65 increased their response to flu vaccines.

It did, by about 20 percent. Yet behind the test was a bigger question about whether any drug can slow or reverse the symptoms of old age. Novartis's study on everolimus, which looked at whether the immune system of elderly people could be made to act younger, has been called the "first human aging trial."

Last week a Boston company, PureTech Health, said it was licensing two drug molecules, and the right to use them against aging-related disease, from Novartis and making the research the basis of a startup company, resTORbio. The company says it will further test whether such drugs can rejuvenate aged immune cells.

The drug Novartis tested is a derivative of rapamycin, a compound first discovered oozing from a bacterium native to Easter Island, or Rapa Nui, and named after it. Thanks to its broad effects on the immune system, rapamycin has already been used in transplant medicine as an immune suppressant and a version is sold by Novartis as the anticancer prescription Afinitor.

Adding genetic circuits to cells lets researchers control their actions, setting the stage for new ways to treat cancer and other diseases.
Computer hardware is getting a softer side. A research team has come up with a way of genetically engineering the DNA of mammalian cells to carry out complex computations, in effect turning the cells into biocomputers. The group hasn't put those modified cells to work in useful ways yet, but down the road researchers hope the new programming techniques will help improve everything from cancer therapy to on-demand tissues that can replace worn-out body parts.

An alternate theory of evolution: Survival of the friendliest

Two models of evolution: The early interpretation of Darwinian evolution as life-or-death contest is being complemented by an understanding of the importance of cooperation.
It's time to give the violent metaphors of evolution a break.

Violence has been the sire of all the world's values," wrote poet Robinson Jeffers in 1940. "What but the wolf's tooth whittled so fine the fleet limbs of the antelope? What but fear winged the birds, and hunger jeweled with such eyes the great goshawk's head?"

We've taken these metaphors for evolution to heart, reading them to mean that life is a race to kill or be killed. "Darwinian" stands in for "cutthroat," "survival of the fittest" signifies survival of the ruthless. We see selective pressures that hone each organism for success and drive genetic innovation as the natural order of things.

But we know now that that picture is incomplete. Evolutionary progress can be propelled both by the competitive struggle to adapt to an environment, and by the relaxation of selective forces. When natural selection on an organism is relaxed, the creative powers of mutation can be unshackled and evolution accelerated. The relief of an easier life can inspire new biological forms just as powerfully as the threat of death.
