Scientists map huge undersea fresh-water aquifer off US Northeast

In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world. The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles. The study suggests that such aquifers probably lie off many other coasts worldwide, and could provide desperately needed water for arid areas that are now in danger of running out.

Dissemination of pathogenic bacteria by university student's cell phones

New research has demonstrated the presence of S. aureus in 40% of the cell phones of students sampled at a university. S. aureus is a common cause of hospital and community-based infections and is currently considered an important pathogen because of its level of antibiotic resistance. The research, conducted at the Western University of São Paulo, Brazil, is presented at ASM Microbe, the annual meeting of the American Society for Microbiology.

Discovery of the cell fate switch from neurons to astrocytes in the developing brain

During mammalian brain development, neural precursor cells first generate neurons and later astrocytes. This cell fate change is a key process generating proper numbers of neurons and astrocytes. Here we discovered that FGF regulates the cell fate switch from neurons to astrocytes in the developing cerebral cortex using mice. FGF is a critical extracellular regulator of the cell fate switch, necessary and sufficient, in the mammalian cerebral cortex.

PSI imaging helps with rocket launches

Rockets from the European Space Agency (ESA) fly into space with support from the Paul Scherrer Institute (PSI). Imaging carried out at PSI in cooperation with Dassault Aviation ensures the quality of certain components of the Ariane 5 and Vega launch vehicles. With the help of the neutrons generated at the neutron source SINQ, PSI researchers are screening so-called pyrotechnic components that are installed in the ESA rockets. These components, which act like fuse cords and igniters, ensure, among other things, that the booster rockets are dropped at the right hundredth of a second. The Ariane launch on 20 June took place with components that had been examined at PSI.

Algorithm quickly finds hidden objects in dense point clouds

A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.

Kelly Latimer flies at the cutting edge of aviation—and soon, space

Kelly Latimer, 54, is a test pilot for Virgin Galactic and Virgin Orbit—two commercial space companies owned by British billionaire Richard Branson. For space tourism company Virgin Galactic, Latimer flies the giant, twin-fuselage aircraft known as WhiteKnightTwo, which carries a smaller spaceship at its belly to an altitude of up to 50,000 feet before the spaceship detaches and blasts off toward suborbital space. Latimer is also chief test pilot for Virgin Orbit, where she flies a modified 747 plane called Cosmic Girl. The plane carries a rocket under its left wing up to about 35,000 feet in the air, after which the rocket is released and falls for about four or five seconds before igniting and launching toward its intended orbit. Latimer is the only female test pilot out of a total of seven between the two companies.

Cognitive dissonance: Canada declares a national climate emergency and approves a pipeline

On June 18, the government of Canada declared a national climate emergency. The next day, the same government approved the Trans Mountain pipeline expansion (TMX), which will be able to move almost 600,000 barrels of oil per day from Alberta to the Port of Burnaby in British Columbia.

This assistive robot is controlled via brain-computer interface

Researchers at the University of Cassino and Southern Lazio, in Italy, have recently developed a cutting-edge architecture that enables the operation of an assistive robot via a P300-based brain computer interface (BCI). This architecture, presented in a paper pre-published on arXiv, could finally allow people with severe motion disabilities to perform manipulation tasks, thus simplifying their lives.

Perovskite solar cells tested for real-world performance—in the lab

It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.
