NASA's ambitious plan to save Earth from a supervolcano | BBC News
With an supervolcano eruption brewing, it may be the only way to prevent the extinction of the human race...
August 17, 2017: Lying beneath the tranquil settings of Yellowstone National Park in the U.S. lies an enormous magma chamber. It’s responsible for the geysers and hot springs that define the area, but for scientists at Nasa, it’s also one of the greatest natural threats to human civilisation as we know it: a potential supervolcano.
Following an article we published about supervolcanoes last month, a group of Nasa researchers got in touch to share a report previously unseen outside the space agency about the threat—and what could be done about it.
“I was a member of the NASA Advisory Council on Planetary Defense which studied ways for NASA to defend the planet from asteroids and comets,” explains Brian Wilcox of NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology. “I came to the conclusion during that study that the supervolcano threat is substantially greater than the asteroid or comet threat.”
"There are around 20 known supervolcanoes on Earth, with major eruptions occurring on average once every 100,000 years...."

How Google plans to solve the Android update situation
The latest episode of the Android Developers Backstage [1] contains lots of interesting info about Project Treble. To summarize a few highlights (you might also want to head over to my linked article! - at least if you can read german):
# This is really just a first step. The long term plan is to modularize Android further and further to provide OEMs ways to modify Android to their liking without making huge, invasive changes. Basically continually reducing the (relevant) delta between AOSP and OEM Android versions.
# Treble shifts the Android update situation closer to the PC model. Thanks to stable interfaces Google is now focused on working with the chipset vendors to provide universal drivers for their chips - that should work with all devices that are using them. This should reduce complexity in the update process considerably (and hopefully bring more significant updates to drivers during their lifetime)
# All those interfaces between vendor parts and Android Framework are versioned and can tell you about the capabilities of a certain device.
# Google had to do a lot of reshuffling to make Android more flexible. After all they now have to make sure that new Android releases work with all the older vendor parts.
# Having all the communication between vendor parts and Android Framework being handled by Binder is great for security (because of isolation), not so much for performance (because of the overhead it generates). So they also had to shuffle stuff around to make that impact minimal.
# There was a last-minute change in Android 8 for the Pixel devices to prevent a significant performance regression (at least in all the micro-benchmarks) caused by Treble.
# Talks about treble started in May 2015, development took most of the second half of 2016 until now, more than 300 developers worked on it.

Cosmonauts Prep for Spacewalk | International Space Station
Expedition 52 Commander Fyodor Yurchikhin (left) and Flight Engineer Sergey Ryazanskiy (right), of the Russian space agency Roscosmos, have completed a seven hour and 34 minute spacewalk. They re-entered the airlock at 6:10 p.m. EDT.
The two spacewalkers exited the Pirs Docking Compartment Station at 10:36 a.m. EDT. Among their accomplishments was manual deployment of five nanosatellites from a ladder outside the airlock.
One of the satellites, with casings made using 3D printing technology, will test the effect of the low-Earth-orbit environment on the composition of 3D printed materials. Another satellite contains recorded greetings to the people of Earth in 11 languages. A third satellite commemorates the 60th anniversary of the Sputnik 1 launch and the 160th anniversary of the birth of Russian scientist Konstantin Tsiolkovsky.
They also collected residue samples from various locations outside the Russian segment of the station.

Red Supergiant Star Antares: Unknown Force Pulling Parts of the Star's Surface into Space
Classified as a red supergiant of spectral type M1.5Iab, Antares is one of the largest known stars. It is the brightest, most massive, and most evolved stellar member of the nearest OB association (the Scorpius–Centaurus Association).
Antares (/ænˈtɑːriːz/), also designated Alpha Scorpii (α Scorpii, abbreviated Alpha Sco, α Sco), is on average the fifteenth-brightest star in the night sky, and the brightest star in the constellation of Scorpius.
https://en.wikipedia.org/wiki/Antares
A trio of researchers with Universidad Catolica del Norte and the Max-Planck-Institut fur Radioastronomie has found evidence that suggests that convection alone cannot account for the amount of material that is pulled from the surface of a red supergiant.
In their paper published in the journal Nature, K. Ohnaka, G. Weigelt and K.-H. Hofmann describe their study of the supergiant Antares, what they found and why they now believe there is an unknown force pulling some parts of the star's surface into space.
The red supergiant Antares is familiar to stargazers as the heart of the scorpion in the Scorpius constellation. It is thought to be between 15 and 18 times as massive as the Sun, and have around 883 times its radius. Hence, if placed in the center of the Solar System, its outer surface would lie between the orbits of Mars and Jupiter—it is also at the end stages of its existence.
Prior research has also shown that red giants have atmospheres that extend far from their surface—Antares, for example, has some regions that would extend all the way to Mars if it were in our solar system.
The prevailing theory explaining such far-reaching regions has been convection cells carrying the material away from the star. But now, that theory might have to be changed as the researchers with this new effort have found evidence that suggests convection alone could not lift as much material from Antares as they have measured.

Kedumba Tributary, Blue Mountains
In driving rain, the Kedumba Creek splits and overflows into many small streams. The Katoomba Falls becomes a raging torrent and smaller waterfalls appear along the escarpment. In dry times, the paths cut by these streams may be mistaken as walking trails with dangerous results.

Elegant dispersal
Bloody crane's-bill (Geranium sanguineum)
Svartskog, Norway
Taking the time to observe the development of the seeds of the many plant species is perhaps not remotely as interesting as watching the colorful blossoms of summer. Yet many know and love the seeds of the dandelions, and you definitely have some other plant species in your garden, then it is easy to just take a regular glance at one or more flowers and see how each slowly transforms to a fruit. And what kind of fruit it develops can be truly amazing and sometimes requires a magnifying glass. Or a macro lens.
This species got its name from the long beak-shaped fruit, and looks really amazing long before the seeds are ripe and ready to be transported as far from the plant as possible. Some species rely on attaching their seeds to fur or feathers, others to be carried by the wind, and some simply eject the seeds into the air.
Although I have plenty of this species growing around my house, I rarely find such beautiful specimens like this one. I still am looking for one where all four are ejected, but this one will most definitely do in the meantime.

The human brain has a region of cells responsible for linking sensory cues to actions and behaviors and cataloging the link as a memory. Cells that form these links have been deemed highly stable and fixed.
Now, the findings of a Harvard Medical School study challenge that model, revealing that the neurons responsible for such tasks may be less stable, yet more flexible than previously believed.
The results, published Aug. 17 in the journal Cell, cast doubt on the traditional notion that memory formation involves hardwiring information into the brain in a fixed and highly stable pattern.
The researchers say their results point to a critical plasticity in neuronal networks that ensures easier integration of new information. Such plasticity, the researchers said, allows neuronal networks to more easily incorporate new learning, eliminating the need to form new links to separate neurons every time. Furthermore, they said, once a memory is no longer needed, neurons can be more easily reassigned to other important tasks.
Our experiments point to far less stability in neurons that link sensory cues to action than we would have expected and suggest the presence of much more flexibility, and indeed a sort of neuronal efficiency said study senior author Chris Harvey an assistant professor of neurobiology at Harvard Medical School. We believe this trade-off ensures the delicate balance between the ability to incorporate new information while preserving old memories.
The Harvard Medical School study involved experiments with mice repeatedly running through a virtual maze over the course of a month.
Analyzing images of brain activity in a brain region involved in navigational decision making, the researchers noted that neurons did not stabilize into a pattern.
Instead, the set of neurons forming the mice’s maze-running memories kept changing for the duration of the study.
In fact, neurons kept switching roles in the memory pattern or left it altogether, only to be replaced by other neurons.
Individual neurons tended to have streaks where they’d do the same thing for a few days, then switch Harvey said. Over the course of weeks, we began to see shifts in the overall pattern of neurons.
The experiments are part of the research team’s ongoing efforts to unravel the mysteries of memory formation and, specifically, how the brain captures external cues and behaviors to perform recurring tasks such as navigating a space using landmarks. Imagine a person driving a familiar route to the grocery store who sees the bank and turns right at that corner without even having to think about it consciously.
To mimic that process, mice in the study were trained to run down a virtual passage, a computer-generated maze displayed on large screens in front of a treadmill, and turn right if they were given a black cue or left if they were given a white cue.
Researchers imaged hundreds of neurons in the part of the brain responsible for spatial decision making as the mice were galloping down the virtual maze.
Once the navigational links were firmly established in the mice’s brains over the course of a few weeks, the researchers expected the activity of the neurons to look the same from day to day. During maze runs that occurred within 24 hours of each other that was, indeed, the case.
Neurons that activated in response to the white cue could be distinguished from neurons that activated in response to the black cue.
However, over the course of several weeks the line between cues in individual neurons blurred and the memory pattern began to drift across neurons, the researchers observed.
A neuron that had been associated with the black cue would lose its specialization and be replaced by another, or it might even become associated with the opposite white cue. This came as a surprise to the researchers.
We were so sure that the neurons would be doing the same thing every day that we designed the study expecting to use the stable pattern as a baseline said study first author Laura Driscoll a graduate student in the neurobiology department. After we realized the neurons were changing roles, we had to rethink parts of the study.
The researchers tested how the pattern changed when they added shapes as a third cue while the mice were navigating the maze. After some reassignment of individual neurons as the mice learned the new cue, the researchers found very little change to the overall activity pattern.
This finding supports the idea that networks of neurons storing memories stay flexible in order to incorporate new learning, the researchers say.
The researchers hypothesize that neuronal stability may differ across various brain regions, likely depending on how often the skill or memory they encode needs to be modified. For a task like navigation, which frequently requires the brain to incorporate new information, it would make sense that the neurons remain flexible, Harvey said. However, more instinctual physical responses, such as blinking, may be hardwired with little neuronal drift over time.
The results provide a fascinating early glimpse into the complexities of memory formation, Driscoll said. To elucidate the big picture of memory formation and storage across brain regions, researchers say they hope to study other areas of the brain involved with different types of decision-making and memories.
I hope this research inspires people to think of memory as something that is not static Harvey said. Memories are active and integrally connected to the process of learning.

People close to Steve Bannon tell NBC News he feels on safe ground amid White House infighting stemming from President Donald Trump’s divisive response to the violence in Charlottesville.
Bannon, who has rarely given on-the-record interviews since assuming his position as Trump’s chief White House strategist, reached out to speak with three news outlets in the past 48 hours, using those conversations to criticize colleagues, threaten to fire others and appearing to relish the ongoing national racial tensions.
His comments signal that Bannon, the former head of Breitbart News, is digging in for the long haul amid the turmoil and turnover that has roiled Trump’s cohort of top advisers in recent weeks.

The Massive Stars in Westerlund 1.
Image Credit: ESA/Hubble & NASA
Explanation: Star cluster Westerlund 1 is home to some of the largest and most massive stars known. It is headlined by the star Westerlund 1-26, a red supergiant star so big that if placed in the center of our Solar System, it would extend out past the orbit of Jupiter. Additionally, the young star cluster is home to 3 other red supergiants, 6 yellow hypergiant stars, 24 Wolf-Rayet stars, and several even-more unusual stars that continue to be studied. Westerlund 1 is relatively close-by for a star cluster at a distance of 15,000 light years, giving astronomers a good laboratory to study the development of massive stars. The featured image of Westerlund 1 was taken by the Hubble Space Telescope toward the southern constellation of the Altar (Ara). Although presently classified as a "super" open cluster, Westerlund 1 may evolve into a low mass globular cluster over the next billion years.

Perseid Meteors over the Pyrénées
This mountain and night skyscape stretches across the French Pyrenees National Park on August 12, near the peak of the annual Perseid meteor shower. The multi-exposure panoramic view was composed from the Col d'Aubisque, a mountain pass, about an hour before the bright gibbous moon rose. Centered is a misty valley and lights from the region's Gourette ski station toward the south. Taken over the following hour, frames capturing some of the night's long bright Perseid meteors were aligned against the backdrop of stars and Milky Way.
