The air around the comet that Rosetta landed on has plenty of oxygen, scientists say, potentially changing our understanding of the beginnings of the solar system.

In current theories, oxygen shouldn’t be able to exist in high quantities, and should instead have combined with hydrogen and formed water. But oxygen is the fourth most common gas around the comet.

Professor Kathrin Altwegg, project leader for Rosetta’s Rosina mass spectrometer instrument, said: “We had never thought that oxygen could ‘survive’ for billions of years without combining with other substances.”

This is our chance to make a real difference to how ageing research progresses and how people view ageing.

We need fifty people to make a real change in funding policy so we can work towards healthy longevity.

In a study published today in the Astrophysical Journal Letters, scientists from the University of New Hampshire and colleagues answer the question of why NASA’s Voyager 1, when it became the first probe to enter interstellar space in mid-2012, observed a magnetic field that was inconsistent with that derived from other spacecraft observations.

Voyager 1 sent back several different indications that it had punched through the edge of our sun’s massive protective bubble inflated by solar wind—the heliosphere—after a 35-year journey. But the magnetic field data gathered by the spacecraft was not what scientists had expected to see. The UNH-led study resolves the inconsistencies.

“There are still naysayers out there regarding Voyager 1 crossing through the heliopause—the edge of the heliosphere,” says astrophysicist Nathan Schwadron of the UNH Institute for the Study of Earth, Oceans, and Space and department of physics and lead author of the paper. “And the reason for this doubt is that when the spacecraft supposedly broke through the heliopause we should have seen some sort of distinctive shift in the magnetic field from one medium to the other,” Schwadron says.

British researchers have built a working Star-Trek-style “tractor beam” — a device that can attract or repel one object to another from a distance. It uses high-amplitude soundwaves to generate an acoustic hologram that can grasp and move small objects.

Stunning, truly.

NASA has presented us with yet another stunning, backlit view of Pluto, taken by the New Horizons spacecraft during its flyby in July. The photo adds to the growing repertoire of Pluto images that are slowly being downloaded from the probe and released by the space agency. This one shows Pluto’s crescent in full, spectacular detail, completing the partial crescent image that NASA released in mid-September.

The image was taken by New Horizons’ Multi-spectral Visible Imaging Camera (MVIC), just 15 minutes after making its closest approach of Pluto on July 14th. It was taken from 11,000 miles away, when New Horizons looked back at Pluto toward the Sun. The photo shows the hazy layers of the dwarf planet’s atmosphere, as well as the mountains on Pluto’s surface that surround the icy plains of Sputnik Planum.

Can black phosphorous rival #graphene?

A new experimental revelation about black phosphorus nanoribbons should facilitate the future application of this highly promising material to electronic, optoelectronic and thermoelectric devices. A team of researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) has experimentally confirmed strong in-plane anisotropy in thermal conductivity, up to a factor of two, along the zigzag and armchair directions of single-crystal black phosphorous nanoribbons.

“Imagine the lattice of black phosphorous as a two-dimensional network of balls connected with springs, in which the network is softer along one direction of the plane than another,” says Junqiao Wu, a physicist who holds joint appointments with Berkeley Lab’s Materials Sciences Division and the University of California (UC) Berkeley’s Department of Materials Science and Engineering. “Our study shows that in a similar manner heat flow in the black phosphorous nanoribbons can be very different along different directions in the plane. This thermal conductivity has been predicted recently for 2D black phosphorous crystals by theorists but never before observed.”

Wu is the corresponding author of a paper describing this research in Nature Communications titled “Anisotropic in-plane thermal conductivity of black phosphorus nanoribbons at temperatures higher than 100K.” The lead authors are Sangwook Lee and Fan Yang.

Nissan says its autonomous car will be ready for sale to consumers by 2020.

Nissan Motor Co. is aggressively pushing forward with plans for a mostly autonomous car that will be ready for sale to consumers by 2020, putting it well ahead of its global competitors.

Chief Executive Carlos Ghosn said the technology would be ready by the Japanese auto maker’s self-imposed deadline—though he wasn’t sure if it would be legal on any nation’s roads.

“We are very excited about it and we want to come as soon as…
