Artificial intelligence replaces physicists

Physicists are putting themselves out of a job, using artificial intelligence to run a complex experiment. The experiment created an extremely cold gas trapped in a laser beam, known as a Bose-Einstein condensate, replicating the experiment that won the 2001 Nobel Prize.

 students at University of California San Diego launched a rocket with a completely 3D-printed engine. Students for the Exploration and Development of Space claims to be the first university group to do this.
Their rocket, dubbed Vulcan-1, is 19 feet long, 8 inches in diameter, and capable of 750 pounds of thrust. It's powered by a cryogenic combination of liquid oxygen and refined kerosene. The rocket traveled approximately 4000 feet.
NASA’s been working on 3D-printing rocket engines for some time now. Last winter they put some 3D-printed parts through a fiery test. The private space industry, too, is working on rockets with 3D printed components. In 2014, SpaceX's Falcon 9 launched with a 3D-printed valve. But as far as we know, this is the first time a student-made completely 3D-printed rocket has blasted off. (Bagaveev Corporation, one of the project's Kickstarter sponsors, was the first to launch a fully 3D printed rocket engine that the San Diego team knows of.)


Watch it fly!

Chasma Boreale and North Polar Ice Cap of Mars

Mars has bright polar caps of ice that are easily visible from telescopes on Earth. A seasonal cover of carbon-dioxide ice and snow is observed to advance and retreat over the poles during the Martian year. Scientists using radar data from NASA's Mars Reconnaissance Orbiter (MRO) have found a record of the most recent Martian ice age recorded in the planet's north polar ice cap.

This image is a simulated 3-D perspective view of Chasma Boreale, a canyon that reaches 570 kilometers (350 miles) into the north polar cap. It was created from image data taken by the THEMIS instrument on NASA's Mars Odyssey spacecraft. Canyon walls rise about 1,400 meters (4,600 feet) above the floor of Chasma Boreale. Where the edge of the ice cap has retreated, sheets of sand are emerging that accumulated during earlier ice-free climatic cycles. Winds blowing off the ice have pushed loose sand into dunes, then driven them down-canyon in a westward direction.

Today would be Sally Ride's 65th birthday. Ride was a pioneer in many ways. She was among the candidates in NASA's first integrated astronaut class. The class of 1978 included for the first time women, blacks, and Asians. Ride was not only America's first woman in space, she was also a professor of physics and an educator. As an astronaut she flew on the Space Shuttle twice as a mission specialist, logging a total of more than 340 hours in space.

 Multiple Sclerosis (MS) is a neurological disease, characterised by demyelination and the onset of chronic, neurodegenerative damage of the central nervous system. Right now, its causes are unknown although various self-immune mechanisms are known to be involved.


The research community is already aware that genetic variants lead to changes in the code of the DNA component and that in order to understand their biological effects, the effects of the expression of the corresponding gene need to be studied, in other words, the changes in the messenger RNA and the proteins.
The Neurogenomiks research group, linked to the Achucarro Basque Centre for Neuroscience (EHUgroup) and the University of the Basque Country (UPV/EHU), has just had a research article published in the prestigious scientific publication Journal of Immunology; it details how they have managed to show that the gene known as ANKRD55 produces 3 different transcripts of the messenger RNA, and that the genetic variant associated with MS greatly increases the production of these transcripts.
The lead author of this research, the Ikerbasque researcher Dr Koen Vandenbroeck, stressed that "we have also discovered and proven that this takes place specifically in the case of a particular category of immune cells, the so-called T CD4+ cells. This suggests that ANKRD55 exerts a significant biological function on these cells and which now needs to be deciphered. It is important to point out that the region of the 5qll chromosome contains various known genes that play a role in immune response. Nevertheless, our data clearly point to ANKRD55 as the key gene in this area.
T CD4+ cells are crucially important in generating protective cell immune responses and they are thought to be deregulated in multiple sclerosis. This study concludes that the ANKRD55 gene may play a fundamental role in this deregulation.

 What a error of calculation do with your life? Overthinking the problem ruins the outcome!!! Cool NERD STUFF ...
Have a nice weekend everyone

A jewel of the southern sky, the Great Carina Nebula, also known as NGC 3372, spans over 300 light-years, one of our galaxy's largest star forming regions. Like the smaller, more northerly Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye, though at a distance of 7,500 light-years it is some 5 times farther away. This gorgeous telescopic close-up reveals remarkable details of the region's central glowing filaments of interstellar gas and obscuring cosmic dust clouds. The field of view is over 50 light-years across. The Carina Nebula is home to young, extremely massive stars, including the stars of open cluster Trumpler 14 (below and right of center) and the still enigmatic variable Eta Carinae, a star with well over 100 times the mass of the Sun. Eta Carinae is the brightest star, seen here just above the dusty Keyhole Nebula (NGC 3324). While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that the Great Carina Nebula has been a veritable supernova factory.
