Autism breakthrough: One protein's sweeping influence on development of autism revealed

 AutismAs many as a third of autism cases could be explained by a scarcity of a single protein in the brain, Toronto scientists have revealed. The findings provide a unique opportunity to develop treatments for a disorder that is rooted in a motley crew of genetic faults.

Researchers induced autistic-like behaviour in mice by lowering the levels of a protein called nSR100 (also known as SRRM4), which is important for normal brain development. The study, published in the December 15 issue of the journal Molecular Cell, builds on the teams' previous work which showed that the nSR100 protein was reduced in the brains of autistic people.

The teams were led by Professors Benjamin Blencowe of the University of Toronto's Donnelly Centre and Sabine Cordes of the Department of Molecular Genetics and Sinai Health System's Lunenfeld-Tanenbaum Research Institute.

Newton and the Equations of Nature by @techreview

 PhysicsPublished on Dec 22, 2016 by @techreview
We all know Isaac Newton for something that he never did: discovering gravity when an apple fell on his head and woke him up from a nap under a tree. This is what actually happened.

Deep probe of antimatter puts Einstein’s special relativity to the test. By @NewsfromScience

 PhysicsAfter decades of effort, physicists have probed the inner working of atoms of antihydrogen—the antimatter version of hydrogen—by measuring for the first time a particular wavelength of light that they absorb. The advance opens the way to precisely comparing hydrogen and antihydrogen and, oddly, testing the special theory of relativity—Albert Einstein’s 111-year-old theory of how space and time appear to observers moving relative to one another, which, among other things, says that nothing can move faster than light.

"It's a stunning result," says Alan Kostelecky, a theorist at Indiana University in Bloomington who was not involved in the work. For decades, experimenters have dreamed of measuring the spectrum of light absorbed by antihydrogen, Kostelecky says. "Here it is. They're doing it now."

Just as an atom of hydrogen consists of an electron bound to a proton, antihydrogen is an antielectron (or positron) bound to an antiproton. Of course, antihydrogen doesn't occur in nature. Because matter and antimatter particles annihilate each other, antihydrogen would vanish as soon as it touched matter. So physicists must make the stuff in the lab. Still, they expect the properties of antihydrogen to exactly mirror those of hydrogen.

His teachers called him lazy.


Léon Foucault

Léon Foucault was born in Paris, France, on September 18, 1819. He made his first major scientific discovery in the 1850s, when he exhibited experimental proof of the earth's rotation using Foucault's Pendulum. In 1852, he further demonstrated the earth's rotation with a gyroscope. In 1862, he became the first to accurately identify the speed of light. He died on February 11, 1868, in Paris, France.

Discoveries and Inventions

While working under Donné, Foucault discovered a means of taking photos through the lens of a microscope. In the process, he invented a strong source of light for illuminating his microscopic subjects. In 1845, Foucault took over Donné's position as editor of the scientific newspaper Journal des Débats.

Foucault made his first major scientific discovery in the early 1850s, when he exhibited experimental proof of the earth's rotation through the use of a pendulum, aptly dubbed Foucault's Pendulum. In 1852, he extrapolated on this principal by demonstrating the earth's rotation with a gyroscope. Three years later, Foucault earned the Copley Medal of the Royal Society for his efforts in proving Earth's diurnal rotation.

In 1855, Foucault was appointed physicist by the Imperial Observatory, where he experimented with improvements to telescope technology (including the use of silvered concave mirrors) and land-surveying equipment.

In 1862, Foucault became the first to accurately identify the speed of light. He did so by using a rotating mirror in an enclosed space. Afterward, his experiments became increasingly focused on precision engineering.

Her work with differential equations contributed to advances in the study of fluid dynamics


Dr. Olga Ladyzhenskaya

Mathematician whose work with differential equations contributed to advances in the study of fluid dynamics in areas like weather forecasting, oceanography, aerodynamics and cardiovascular science, died on Jan. 12 in St. Petersburg, Russia. She was 81.

The cause of death had not been determined, according to a spokeswoman for the Association for Women in Mathematics, in College Park, Md. Dr. Ladyzhenskaya was a member of the organization.

Her primary work was on calculations that were developed in the 19th century to explain the behavior of fluids and known as Navier-Stokes equations. As a researcher first at St. Petersburg University and later at the Steklov Institute of Mathematics, also in St. Petersburg, she worked through the solutions for the equations, which show how a number of variables relate in time and space.

Among other practical uses, the equations enable meteorologists to predict the movement of storm clouds.
