Looking back 3.8 billion years into the root of the ‘Tree of Life’

“The ribosome is one of the primary target for antibiotics, so understanding its architecture and consistently throughout biology could be of great benefit,” said Williams. “By studying the ribosome, we can start thinking about biology in a different way. We can see the symbiotic relationship between RNA and proteins.”
While the ribosomal core is the same across species, what’s added on top differs. Humans have the largest ribosome, encompassing some 7,000 nucleotides representing dramatic growth from the hundred or so base pairs at the beginning.
“What we’re talking about is going from short oligomers, short pieces of RNA, to the biology we see today,” said Williams. “The increase in size and complexity is mind-boggling.”

Missing link found between turbulence in collapsing star and hypernova, gamma-ray burst
Posted by Andreas Matt in categories: space, supercomputing
A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous magnetic fields needed to explode the star and fire off bursts of gamma rays visible halfway across the universe.
The results of the simulation, published online Nov. 30 in advance of publication in the journal Nature, demonstrate that as a rotating star collapses, the star and its attached magnetic field spin faster and faster, forming a dynamo that revs the magnetic field to a million billion times the magnetic field of Earth.
A field this strong is sufficient to focus and accelerate gas along the rotation axis of the star, creating two jets that ultimately can produce oppositely directed blasts of highly energetic gamma rays.

See The Amazon Drone That Will Deliver In 30 Minutes Or Less
Posted by Dan Kummer in categories: drones, transportation
Amazon says drones can deliver packages weighing up to 5 pounds within 30 minutes.
“In time, there will be a whole family of Amazon drones,” says narrator Jeremy Clarkson, the former BBC “Top Gear” cohost who is working on a similar show for Amazon. “Different designs for different environments.”

Is Media Attention Hindering The Development Of Artificial Intelligence?

As the line between tabloid media and mainstream media becomes more diffuse, news items such as Ebola, pit bulls, Deflategate, and Donald Trump can frequently generate a cocktail of public panic, scrutiny, and scorn before the news cycle moves on to the next sensational headline. According to Robotics Expert and self-proclaimed “Robot Psychiatrist” Dr. Joanne Pransky, the same phenomenon has happened in robotics, which can shape public perception and, by extension, the future development of robots and AI.
“The challenge, since robotics is just starting to come into the mainstream, is that most of the country is ignorant. So, if you believe what you read, then I think people have a very negative and inaccurate picture (of robotics),” Pransky said. “I spend a lot of time bashing negative headlines, such as ‘ROBOT KILLS HUMAN,’ when actually the human killed himself by not following proper safety standards. A lot of things are publicized about robotics, but there’s nothing about the robot in the article. It leads people on the wrong path.”
