Study refutes ice-free corridor theory by suggesting passageway became habitable 12,600 years back

Study refutes ice-free corridor theory by suggesting passageway became habitable 12,600 years back

A new study suggests that the long considered theory on how the first humans have traveled to United States could be not correct. General perception is first Americans have migrated to the continent through an ice-free corridor stretching from Alaska to Montana. But a new study has something different to offer.

Deep Space Industries to land spacecraft on near-earth asteroid by 2020

Deep Space Industries to land spacecraft on near-earth asteroid by 2020

Deep Space Industries has shared about its plan to land a 110-pound spacecraft on a near-earth asteroid by 2020. The company has yet to finalize asteroid on which the spacecraft, Prospector-1, would land in 2020.

Main aim of the spacecraft would be to know the value of its resources for mining. Also, the company would put its water-based propulsion system to an interplanetary test. DSI’s board chairman and co-founder said that they have worked hard to reach at this level.

Lockheed Martin signs a contract with NASA to launch and deploy its 6U SkyFire CubeSat using SLS

NASA’s Space Launch System will be launched likely in late 2018 or early 2019 with an aim to show it has the ability to deliver the Orion spacecraft into a lunar orbit. Along with it, 13 bays for CubeSats, shoe-box sized payloads would also be delivered into deep space.

Respective payload operators have been working to get things finalized with NASA. On Monday, Lockheed Martin announced that it has signed a contract with NASA to launch and deploy its 6U SkyFire CubeSat.

SpaceX sends its first Raptor engine to its Texas test facility for firing

SpaceX sends its first Raptor engine to its Texas test facility for firing

SpaceX president Gwynne Shotwell shared at the Small Satellite Conference in Utah that the company has sent its first Raptor engine to their McGregor, Texas test facility for firing. The Raptor is SpaceX’s next generation of rocket engine.

In comparison with the Merlin engines that power SpaceX’s Falcon 9 rocket, the Raptor is three times more powerful. The latter will be used to power SpaceX’s next generation of rocket, Mars Colonial Transporter (MCT).

New video camera captures rocket plume in unprecedented detail

New video camera captures rocket plume in unprecedented detail

Now, NASA has a camera that shows every minute detail of a rocket plume in unprecedented detail. The new High Dynamic Range Stereo X (HiDyRS-X) is able to record multiple slow motion exposures at one go by combining these shots into a high-definition video.

A rocket plume cannot be seen clearly because of its extreme brightness. This is one of the main reasons that it has never been captured properly. The new camera launched during NASA’s recent space launch test is able to show rocket plume in a great detail.

Quantum Computing: MIT researchers develop prototype chip that traps ions in electric field

Quantum Computing: MIT researchers develop prototype chip that traps ions in electric field

Researchers from MIT and MIT Lincoln Laboratory have taken a step towards practical quantum computers. They have developed a prototype chip that can trap ions in an electric field along with built-in optics.

One of the study researchers Rajeev Ram, a NIT Professor of electrical engineering, said that they aim to take external laboratory and miniaturize technology on a chip. Study researchers have designed and built a set of on-chip optical components that can channel laser light towards individual ions.

Dust-sized, wireless sensors could one day monitor body from within in real time

Dust-sized, wireless sensors could one day monitor body from within in real time

A first dust-size, wireless sensor has been developed that can be implanted the body to monitor internal nerves, muscles or organs in real time. The neural dust could prove beneficial in ultrasound that is used both to power and read out the measurements.

The neural dust was implanted in the muscles and peripheral nerves of rats. One of the study authors Michel Maharbiz said that they see the utilization of neural dust not only within nerves and brain, but to at a much wider scale.

Sunflowers turn their faces 180 degrees east to west tracing sun’s path

Sunflowers turn their faces 180 degrees east to west tracing sun’s path

Sunflowers change their direction as per sunlight. Every day, young sunflowers track the sun’s path across the sky and doing so, they move their faces 180 degrees from east to west. During the night also, their movement continues as then they reorient themselves and come to their original position, in the east, in the hope of dawn.

Prof. Stacey Harmer, a circadian biologist from UC Davis, has explained in the journal Science as to how sunflowers move and why. The research team set up an experiment in which it planted a field of sunflowers and observed what happened.

Flooding in China in 1900 BC termed as major event in new research paper

Researchers unveil of one of world’s largest known flooding in China in about 1900 BC

A research paper published in the journal Science has unveiled about geological evidence of a catastrophic flood in the Yellow River around 1900 BC. While carrying out the fieldwork in 2007, researchers from Nanjing Normal University have come across sediments from the ancient dam.

MIT researchers develop new technique that allows you to reach in and touch objects in videos

MIT researchers develop new technique that allows you to reach in and touch objects in videos

Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed an imaging technology called Interactive Dynamic Video (IDV) that allows you to reach in, push, pull, and poke and prod objects in videos.

The technology works with the use of traditional cameras and algorithms. Using these mediums, IDV looks at the almost invisible vibrations of an object to come up with video simulations that can be used by users to virtually interact with.
