Matthew Powner and John Sutherland at the Medical Research Council in Cambridge, U.K., came up with the first plausible chemical reactions that could have synthesized pyrimidines on early Earth. 

Starting with aldehyde, a simple sugar thought to have been present on early Earth, Powner and colleagues performed a handful of steps to transform the aldehyde into two compounds resembling adenine- and guanine-containing nucleotides (two building blocks within RNA, DNA's 'cousin').

The resemblance wasn’t perfect: a carbon atom was bound to an oxygen atom instead of a hydrogen atom at the base of each.

Powner says he and his colleagues are now looking for solutions. If they succeed, the path from simple chemicals to life will be a whole lot clearer.
Between 6 million to 7.5 million existing jobs are at risk of being replaced over the course of the next 10 years by some form of automation, according to a new study by financial services firm Cornerstone Capital Group.

Representing 38% of the current retail workforce and comprised of 16 million workers, the retail industry could actually lose a greater proportion of jobs to automation than manufacturing.

There will also be fewer sales jobs, as more and more consumers use in-store smartphones and touchscreen computers to find what they need, said John Wilson, head of research at Cornerstone. There will still be some sales people on the floor, but just not as many of them.
Researchers used a 3D printer to build the scaffolding of the organs, weaving layers of gelatin to create tiny (15 x 15 millimeter) ovaries on glass slides. They then tested the scaffolds by embedding tiny sacs composed of hormone-secreting cells containing maturing eggs.

The follicles on the scaffolding were able to hook up with the blood supplies of the mice within a week, the ovaries eventually releasing eggs. Of seven mice that received the ovaries, three gave birth, producing healthy offspring.

The mouse mothers also lactated normally, a sign that the follicles in their ovaries were producing the correct amount of hormones.
Most people know Tesla for its high-end electric cars and Elon Musk, its visionary owner.

Tesla isn't just leading the push for electric cars – it's also pushing the boundaries of self-driving car technology with its Autopilot system.

But of course, once you take the driver out of the equation, people are going to worry about whether the software behind the wheel will get them killed.

Humans like to be in control of their own fates, or at least know that a trained human who also has a desire to stay alive is in control. So Tesla has a tough sell ahead of them.

However, this dashcam video will sure help Tesla's cause.

Seeing the Autopilot in action, under normal road conditions and with a normal person inside, avoiding a collision speaks volumes about the work the company's developers have been putting in.
Various science fiction movies have suggested that perhaps cryogenic sleep is the best option when considering interstellar traveling. 

Replacing the body's water supply with antifreeze, cryogenics works by preserving the body through vitrification. The process replaces water in the cells and allows tissue to cool to a rather chilly -220 degrees Fahrenheit.

The idea is to freeze the body just after the heart stops but before the brain has a chance to shut down.

Done properly, it’s possible to retrieve a life from said state. However, the most difficult task, re-warming a person to proper temperature, is proving to be the most difficult piece in the puzzle.
