Science. Science. New Sciences. SCIENCE. Science/Nature. Life. Genetics. 10 Awesome Accidental Discoveries. "Big things have small beginnings. " All right, so that's actually a quote from Michael Fassbender in (Prometheus,) but nothing could be more true for radio astronomer duo Robert Wilson and Arno Penzias. The secret to discovering the prevailing theory to how the universe was made began with noise, like common radio static. In 1964, while working with the Holmdel antenna in New Jersey, the two astronomers discovered a background noise that left them perplexed. After ruling out possible interference from urban areas, nuclear tests, or pigeons living in the antenna, Wilson and Penzias came across an explanation with Robert Dicke's theory that radiation leftover from a universe-forming big bang would now act as background cosmic radiation.

In fact, only 37 miles from the Holmdel antenna at Princeton University, Dicke and his team had been searching for this background radiation. ITER - the way to new energy.

The genome sequence of a 24,000-year-old young Siberian individual found in Russia shows that 14 to 38 percent of modern Native American’s ancestry came from this youngster’s gene pool, suggesting First Americans came directly from Siberia.

The new study shows that ancestors of Native Americans migrated to the Americas from Siberia and not directly from Europe. Painting by G. Mülzel. The Paleolithic skeleton was first discovered in the late 1920s near the village of Mal’ta in south-central Siberia, and since then it has been referred to as the Mal’ta child because until this DNA study the biological sex of the skeleton was unknown. “Now we can say with confidence that this individual was a male,” said Dr Kelly Graf from Texas A&M University, a co-author of the paper published in Nature. Dr Graf with colleagues used material from the boy’s upper arm to sequence his mitochondrial and nuclear genomes. The DNA study performed on the boy is the oldest complete genome of a human sequenced so far. Ancient European hunter-gatherer was dark-skinned and blue-eyed caveman. A recent analysis on DNA taken from the wisdom tooth of a 7,000-year-old human found in Spain in 2006 has overturned the popular image of light-skinned European hunter-gatherers.

The study revealed that the individual had dark hair, the dark-skinned genes of an African, though scientists don’t know this exact skin tone, and blue-eyes, which were thought to have been brought to Europe by late-arriving farmers who invaded the continent more than 5,000 years ago. The new study, published in the journal Nature and led by Inigo Olalde of Spain’s Institut de Biologia Evolutiva in Barcelona, involved the first ever analysis of a pre-agricultural European genome and has given scientists an unprecedented glimpse of modern humans in Europe before the rise of farming.

The skeletons of two Mesolithic men were discovered in 2006 in a cave system in the Cantabrian Mountains, near León in northwest Spain. The first unexpected finding was the fact the individual had dark skin. By April Holloway. Joseph-Louis Lagrange. Joseph-Louis Lagrange (born Giuseppe Lodovico Lagrangia [1][2][3] (also reported as Giuseppe Luigi Lagrangia [4]), 25 January 1736 in Turin, Piedmont; died 10 April 1813 in Paris) was an Italian Enlightenment Era mathematician and astronomer.

He made significant contributions to the fields of analysis, number theory, and both classical and celestial mechanics. In 1766, on the recommendation of Euler and d'Alembert, Lagrange succeeded Euler as the director of mathematics at the Prussian Academy of Sciences in Berlin, Prussia, where he stayed for over twenty years, producing volumes of work and winning several prizes of the French Academy of Sciences.

Lagrange's treatise on analytical mechanics (Mécanique Analytique, 4. ed., 2 vols. Paris: Gauthier-Villars et fils, 1888–89), written in Berlin and first published in 1788, offered the most comprehensive treatment of classical mechanics since Newton and formed a basis for the development of mathematical physics in the nineteenth century. Scientist Prove DNA Can Be Reprogrammed by Words and Frequencies. By Grazyna Fosar and Franz Bludorf Who=vitaeb THE HUMAN DNA IS A BIOLOGICAL INTERNET and superior in many aspects to the artificial one. Russian scientific research directly or indirectly explains phenomena such as clairvoyance, intuition, spontaneous and remote acts of healing, self healing, affirmation techniques, unusual light/auras around people (namely spiritual masters), mind’s influence on weather patterns and much more.

In addition, there is evidence for a whole new type of medicine in which DNA can be influenced and reprogrammed by words and frequencies WITHOUT cutting out and replacing single genes. Only 10% of our DNA is being used for building proteins. The Russian biophysicist and molecular biologist Pjotr Garjajev and his colleagues also explored the vibrational behavior of the DNA. One can simply use words and sentences of the human language!

But the higher developed an individual’s consciousness is, the less need is there for any type of device! Science. Science. Science. Science. TED Science. SCIENCE. Science, Math & Tech. Not Even Wrong. Graham Farmelo has posted a very interesting interview he did with Witten last year, as part of his promotion of his forthcoming book The Universe Speaks in Numbers. One surprising thing I learned from the interview is that Witten learned Calculus when he was 11 (this would have been 1962). He quite liked that, but then lost interest in math for many years, since no one gave him more advanced material to study. After years of studying non math/physics subjects and doing things like working on the 1972 McGovern campaign, he finally realized physics and math were where his talents lay.

He ended up doing a Ph.D. at Princeton with David Gross, starting work with him just months after the huge breakthrough of asymptotic freedom, which put in place the final main piece of the Standard Model. If only back in 1962 someone had told Witten about linear algebra and quantum mechanics, the entire history of the subject could have been quite different. About the landscape:

Laboratoire de Didactique et d'Epistémologie des Sciences. Forensic Science Central – Forensic Anthropology. Forensic Anthropology Forensic anthropology combines the theories and methods of anthropology, osteology and archaeology with legal investigations. The role of the forensic anthropologist can be varied, including aiding in the collection and analysis of human remains, the identification of victims beyond recognition, the estimation of time since death, and the establishment of injuries and potentially cause of death.

The victims examined by anthropologists are usually in the late stages of decomposition, are completely skeletonised, or have been rendered otherwise unrecognisable by fire damage or other injuries. The forensic anthropologist will sometimes be called in when suspected human remains are first discovered to aid in the excavation and initial analysis of the bones. Following the careful excavation, documentation and collection of the remains, they are cleaned up in preparation for the analysis. The skull is equally beneficial in the establishment of sex. Roll Over, Pythagoras: the "Holy Grail" of Math May Have Been Found | Think Tank.

What's the Big Idea? The so-called "holy grail" of mathematics may have just been found. Shinichi Mochizuki, a professor at the Research Institute for Mathematical Sciences at Kyoto University, released a 500-page proof of the abc conjecture in number theory which involves the relationship between prime numbers, which I will attempt to describe as succinctly as possible below.

A lot of open theory on prime numbers is based on the abc conjecture. So if verified, Mochizuki's proof would mean a great leap forward in our understanding of primes. This is high-level mathematics, which is even inaccessible to many mathematicians. Part I Part II Part III Part IV Mochizuki is a math genius who received his Ph.D from Princeton University at the age of 22 and hasn't slowed down since.

So what exactly is the abc conjecture? The clearest explanation I could find of the abc conjecture is this single paragraph from the ABC@home project from the Mathematical Institute of Leiden University: Fluid Dynamics. Mandeloculars on Behance. Fibonacci sacred geometry.
