Hi there. Loving doubleTwist, which seems to be the most full-featured player available IMO.

I have a strange issue on my HTC10 running Adroid 7.1.1 (rooted), with doubleTwist 2.7.6: I am unable to select the SD card as a storage device.

Having read another post on here which suggested trying the beta, I signed up and downloaded, but the beta hasn't modified this behaviour.

When I select Settings > Storage I see Internal (23.71 GB) and MicroSD (-0.00 GB). Selecting MicroSD seems to drop back out of this menu without applying anything.

I've checked app permissions, uninstalled / reinstalled (with reboot & checked for left-over app folders in-between). Tips appreciated. Cheers.

CSIRO boss's failed logic over climate science could waste billions in taxes

"Australia will spend billions of dollars on things like dams or desalination plants, but rather than relying on strategic information, these billion-dollar decisions will be based on guesswork."

The Veil Nebula was observed by the NASA/ESA Hubble Space Telescope. Image released Sept. 24, 2015.

The Veil Nebula's beauty belies its violent origins: The structure formed about 8,000 years ago, after a star 20 times more massive than the sun died in a supernova explosion, researchers said.

Polar opposites though they may be, the Amazon and the Sahara have a symbiotic relationship: The nutrients of desert dust blow across the Atlantic and feed the rainforest.

A sad loss of one who deserves to be remembered.
The death of Claudia J. Alexander, a phenomenal woman of #science, was totally overlooked by the social media world. WHY IS THAT??!

Well let me educate you just a little bit.

Claudia J. Alexander, a #NASA scientist who oversaw the dramatic conclusion of the space agency's long-lived Galileo mission to Jupiter and managed the United States' role in the international comet-chasing Rosetta project, died July 11 at Methodist Hospital of Southern California in Arcadia. She was 56.

The cause was breast cancer, said her sister, Suzanne Alexander.

During nearly three decades at NASA's Jet Propulsion Laboratory in La Cañada Flintridge, Alexander was known for her research on subjects including solar wind, #Jupiter and its moons, and the evolution and inner workings of comets.

She was the last project manager of #Galileo, one of the most successful missions for exploring the distant reaches of the solar system. Alexander was leading the mission when scientists orchestrated its death dive into Jupiter's dense atmosphere in 2003, when the spacecraft finally ran out of fuel after eight years orbiting the giant planet.

Most recently, she was Rosetta's U.S. project manager, coordinating with the European Space Agency on the orbiter's journey to rendezvous with the 67P/Churyumov-Gerasimenko comet as it circles the sun.

Colleagues said Alexander was particularly keen on engaging the public in space science.

She spearheaded Rosetta's efforts to involve amateur astronomers through social media and recognize the value of their ground-level observations of the spacecraft's path toward deep space. In particular, she spurred the creation of a Facebook group where members of the amateur community post comments on their sightings and interact with her and other scientists.

“Claudia's vision was to engage and empower the amateur community via various social media… a new wrinkle on the concept” of public engagement in NASA’s missions, said Padma A. Yanamandra-Fisher, a senior research scientist with the Space Science Institute who coordinated the outreach.

"I was a pretty lonely girl. I was the only #black girl in pretty much an all-white school and spent a lot of time by myself -- with my imagination."
- Claudia Alexander

"She had a special understanding of how scientific discovery affects us all, and how our greatest achievements are the result of teamwork, which came easily to her," JPL director Charles Elachi said in a statement. "Her insight into the scientific process will be sorely missed."

Alexander was born in Vancouver, Canada, on May 30, 1959. She moved to the Silicon Valley with her family when she was 1 and grew up in Santa Clara. Her father, Harold Alexander, was a social worker and her mother, Gaynelle, was a corporate librarian for chip-maker Intel.

As an African American in a predominantly white community, Alexander felt isolated. Writing became a refuge for her.

"I was a pretty lonely girl," she recalled in a feature for the University of Michigan's Engineering Magazine. "I was the only black girl in pretty much an all-white school and spent a lot of time by myself — with my imagination."

She wanted to study journalism at UC Berkeley, but her parents "would only agree to pay for it if I majored in something 'useful,' like engineering," she said in an interview for the Rosetta website.

During college she became an engineering intern at NASA's Ames Research Center near San Jose. But she found herself drawn to the space facility and visited it as often as she could. Her supervisor eventually arranged for her to intern in the space science division.

She went on to earn a bachelor's degree in geophysics at UC Berkeley and a master's in geophysics and space physics at UCLA. At the University of #Michigan, she wrote her doctoral thesis on comet thermophysical nuclear modeling and earned a PhD in #atmospheric#oceanic and #space sciences.

In 1986, she joined JPL as a team member for Galileo, which was still years from launching.

In 2000, she became Rosetta's U.S. project scientist at the relatively young age of 40.

"She was always looking to improve the project and make things flow better," said Paul Weissman, an interdisciplinary scientist on Rosetta. "Europeans can be difficult about collaborations. Claudia would get people to open up and work together."

In 2003, she became Galileo project manager, guiding efforts to destroy the venerable spacecraft to prevent it from accidentally crashing into and contaminating any of Jupiter's moons.

She had also served as a science coordinator on the Cassini mission to #Saturn.

In her spare time, Alexander wrote two books on science for children and mentored young people, especially #African American #girls. "She wanted children of color to see themselves as scientists," her sister Suzanne said.

A fan of the steampunk movement in science fiction, Alexander wrote and published short stories in the genre. She wore the Victorian-style clothing associated with steampunk fashion when she taped a #TED talk on how to engage youths in #math and science. Her lecture will be released later this year.

Alexander was never married and had no children. Besides her mother and sister, she is survived by a brother, David Alexander.

This amazing sequence of images taken by #Rosetta 's OSIRIS camera on 29 July show a jet-like feature emerging from the side of comet #67P/C-G's neck, in the Anuket region. As #perihelion2015 approaches on 13 August the spacecraft is witnessing growing activity.
