Revelations in the field of quantum physics have resulted in the discovery of the Amplituhedron, a jewel-like higher dimensional object whose volume elegantly predicts fundamental physical processes that took the brilliant Dr. Richard Feynman hundreds of pages of abstruse mathematics to describe. The theoretical manifold not only enables simple pen-and-paper calculation of physics that would normally require supercomputers to work out, but also challenges basic assumptions about the nature of reality -- forgoing the core concepts of locality and unitarity and suggesting that space and time are merely emergent properties of a timeless, infinitely-sided "master amplituhedron," whose geometry represents the sum total of all physical interactions.

X inactivation is a type of gene dosage compensation. In humans, the sex chromosomes X and Y determine the sex of an individual - females have two X chromosomes (XX), males have one X and one Y chromosome (XY). All of the genes on the Y chromosome are required in male development, while the genes on the X chromosome are needed for both male and female development. Because females receive two X chromosomes, they inherit two copies of many of the genes that are needed for normal function. Extra copies of genes or chromosomes can affect normal development. An example is Down's syndrome, which is caused by an extra copy of part or all of chromosome 21. In female mammals, a process called X inactivation has evolved to compensate for the extra X chromosome. In X inactivation, each cell 'switches off' one of its X chromosomes, chosen at random, to ensure the correct number of genes are expressed, and to prevent abnormal development.

"Read this carefully so that you understand it. When you come home we will show you the model. Lots of love, Daddy." In 1953 Francis Crick, sat down to write his twelve-year-old son Michael a letter explaining his brand-new discovery: the double-helix structure of DNA. Now you can read the original, seven-page hand-written letter, complete with an interactive feature that lets you click for details, context and explanations. Courtesy of the Smithsonian.

How often does a great story dominate the headlines, only to be dropped from the news cycle? How often do journalists tell us of a looming danger or important discovery – only to move quickly to the next new thing? What really happened? How did these events change us? And what are the lingering consequences that may affect our society to this day? These are the questions we are answering at Retro Report, an innovative documentary news organization launched in 2013 as a timely online counterweight to today’s 24/7 news cycle. Combining documentary techniques with shoe-leather reporting, we peel back the layers of some of the most perplexing news stories of our past with the goal of encouraging the public to think more critically about current events and the media in ~10 minute segments.

The 2013 Lasker Awards were announced today. Often called the "American's Nobels", they recognize the contributions of scientists, physicians, and public servants who have made major advances in the understanding, diagnosis, treatment, cure, and prevention of human disease. Included in today's crop of recipients are Dr. Graeme M. Clark, Dr. Ingeborg Hochmair, and Blake S. Wilson who were awarded their prizes for developing the modern cochlear implant. [more inside]

[Pinker] conflates scientific knowledge with knowledge as such. In his view, anybody who has studied any phenomena that are studied by science has been a scientist...If they were interested in the mind, then they were early versions of brain scientists. If they investigated human nature, then they were social psychologists or behavioral economists avant la lettre. Leon Wieseltier pens a response to Steven Pinker's essay on scientism, both in the pages of the New Republic. Others, including some prominent atheists, have taken issue with Pinker as well.
Did you hear that a group of 400 angry farmers attacked and destroyed a field trial of genetically modified rice in the Philippines this month? That, it turns out, was a lie. The crop was actually destroyed by a small number of activists while farmers who had been bussed in to attend the event looked on in dismay.
Massive earthquakes in Chile and Japan have been found to cause the dramatic increase in violent quakes around fracking's largely unregulated wastewater injection wells observed in the Midwest in the past two years, where injected water acts as a lubricant for geological faults that were previously thought to be "dead" or stable for millions of years.
This 1,600-Year-Old Goblet Shows that the Romans Were Nanotechnology Pioneers. The Lycurgus Cup appears opaque green under normal light, but the ancient dichroic glass vessel transforms to a translucent red color when lit from behind. Roman artisans achieved this by impregnating the glass with particles of silver and gold as small as 50 nanometers in diameter. Inspired by the cup, modern researchers have created the world's most sensitive plasmon resonance sensor. [Via]
There’s a moment which comes every time Minh Ha enters the Hall of the Dead: a single, agonizing moment of hope when she sees the streets before the bombs extinguished the lanterns hanging in the trees—when she sees Mother and the aunts exactly as she remembers them, their faces creased like crumpled paper—when she hears them say, “Come to us, child,” in Rong, just as they once did, when handing her the red envelopes of the New Year celebration.

Consumption of lungworm snails can transmit the lungworm parasite Angiostrongylus cantonensis, which can cause meningitis in humans and respiratory problems in dogs, which can eat afflicted slugs while running through open fields. Researchers at the University of Exeter hooked up LEDs to these snails to study their nighttime movements through gardens and how those movements might help them act as a vector for the parasites.

"During the most recent ice age, milk was essentially a toxin to adults because — unlike children — they could not produce the lactase enzyme required to break down lactose, the main sugar in milk. But as farming started to replace hunting and gathering in the Middle East around 11,000 years ago, cattle herders learned how to reduce lactose in dairy products to tolerable levels by fermenting milk to make cheese or yogurt. Several thousand years later, a genetic mutation spread through Europe that gave people the ability to produce lactase — and drink milk — throughout their lives. That adaptation opened up a rich new source of nutrition that could have sustained communities when harvests failed." - The Milk Revolution - how a single mutation expanded (some) of humanity's diet.

The disease that sours oranges and leaves them half green, already ravaging citrus crops across the world, had reached the state’s storied groves. To slow the spread of the bacterium that causes the scourge, they chopped down hundreds of thousands of infected trees and sprayed an expanding array of pesticides on the winged insect that carries it. But the contagion could not be contained.They would have to alter the orange’s DNA — with a gene from a different species. (SLNYT)

Starting on September 22 last year, Professor Robert Fuller of the University of North Georgia spent four months paddling down the Chattahoochee River system, from the Chattahoochee's headwaters in northern Georgia down through the Apalachicola into the Gulf of Mexico, studying water quality along the way. Then he paddled 200 miles through the Gulf, turned at the mouth of the Mobile River, and paddled another 750 miles upstream on the Mobile, Alabama, Coosa, and Etowah Rivers all the way back to northern Georgia—a total of just over 1,500 miles of solo paddling in his Kruger Sea Wind. Along the way, he kept a blog, "ate a lot of Beanie Weenies", and faced difficulties including cold, hunger, injuries, and river obstructions. Incidentally, he did all this while living with leukemia. [more inside]
