SpaceX has come a long way. After being shocked by the absence of NASA’s concrete plans for a manned mission to Mars in the early 2000s, Elon Musk, the well-known entrepreneur and engineer, founded SpaceX in order to establish affordable access to space.
After spending a couple of years on designing, building and testing the first privately developed orbital rockets, the fourth launch of the Falcon 1 rocket into orbit was successful, marking the dawn of private space transportation. With its proven capabilities, SpaceX was awarded a substantial contract from NASA for supply missions to the International Space Station, providing the funding for a rapid development of new launch vehicles.
According to scientists, the ancient lake bed at Gale Crater on Mars is the perfect place to look for ancient habitability.
Microsoft and Google companies want to be central to the development of the thinking machine.
The decision by Microsoft to invest $1 billion in OpenAI, a company jointly founded by Elon Musk, brings closer the time when machines threaten to replace humans in any tasks that humans do today.
OpenAI, which was founded just four years ago, has pioneered a range of technologies which have pushed the frontiers of massive data processing in defiance of the physical and computer capabilities that governed such developments for generations.

Death is inevitable, says Michael Shermer. So why sweat it? Over 100 billion people have died before us, so maybe our fear of death is making our lives worse.
With its 2½-inch wing span, the Wallace’s giant bee is known as the largest bee on earth. But for decades, experts had feared it had gone extinct.
You can amplify light by bouncing it between the horizons of a black hole and a white hole. Now physicists have worked out how to build such a device in the lab.
Researchers have designed a tile set of DNA molecules that can carry out robust reprogrammable computations to execute six-bit algorithms and perform a variety of simple tasks. The system, which works thanks to the self-assembly of DNA strands designed to fit together in different ways while executing the algorithm, is an important milestone in constructing a universal DNA-based computing device.
The new system makes use of DNA’s ability to be programmed through the arrangement of its molecules. Each strand of DNA consists of a backbone and four types of molecules known as nucleotide bases – adenine, thymine, cytosine, and guanine (A, T, C, and G) – that can be arranged in any order. This order represents information that can be used by biological cells or, as in this case, by artificially engineered DNA molecules. The A, T, C, and G have a natural tendency to pair up with their counterparts: A base pairs with T, and C pairs with G. And a sequence of bases pairs up with a complementary sequence: ATTAGCA pairs up with TGCTAAT (in the reverse orientation), for example.

Successful manipulation of optogenomic interfaces can change our entire medical approach to many common neurological abnormalities, as well as better our interactions with machines.
