Think you know how to improve your memory? Think again
We all want to improve our memory, but research unveiled by the University of Toronto’s Dr. Katherine Duncan shows that we need to switch our strategies. Memory isn’t a single entity, and separate memory processes, like formation and recall can be enhanced by different brain states. Her results also revealed a major manipulation which triggers these brain states: novelty. The results were presented at the 2017 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN).
The discovery has been years in the making. Back in 2012, Katherine Duncan used functional magnetic resonance imaging (fMRI) to identify how the brain triggers memory states, uncovering a brain region that detects novelty. She then demonstrated that novelty detection acts like a switch, changing how the brain learns and remembers. Finally, she determined the impact of novelty on human memory. As she puts it, “We find that familiarity increased retrieval of other unrelated memories but reduced the chances for memory formation. On the other hand, novelty enhanced the later formation of distinct memories without worrying about previous experiences.”
Duncan suggests we need to revisit how we make memories. “Your ability to remember something doesn’t just depend on the strength of the memory, it depends on the state that you’re in.” Her work also hints at new strategies to improve memory development. “We’re using what we know about the brain to develop memory enhancing tricks, helping people remember faces, names, and places.”

The speculation around Google’s unified operating system for Android and Chrome OS have mostly died down again, just as the fervor around Android apps on Chrome has similarly lost steam. That doesn’t mean, however, that Google has forgotten about its promise, though. With the launch of its new Pixelbook Chromebook, questions about the versatility of these devices come up again. … Continue reading

On this day:
At 27th October of 1998, Disney's "Lion King II: Simba's Pride" was released on video. "The Lion King II: Simba's Pride" is an American animated direct-to-video musical film sequel to the 1994 animated feature film "The Lion King." Most of the original cast returned to their roles from the first film, apart from Rowan Atkinson, who was replaced by Edward Hibbert as the voice of Zazu for this film and its prequel, "The Lion King 1½." Madge Sinclair, the voice of Simba's mother Sarabi, died after the first film's release, and her character is consequently written out of this sequel.
It's worth remembering that “The Lion King 2: Simba’s Pride” was originally released during an era when Disney was spitting out direct-to-video sequels to practically everything in their library. Few of their cherished classics were spared the rubberstamp treatment, with most destined for the bargain bins of history (or worse, the 'Disney Vault').
They weren't all bad, and the continuation of “The Lion King” (then the highest-grossing animated film of all-time) is perhaps the crowning achievement of the bunch. While not nearly as grand or epic as its theatrical predecessor, this sequel that respects the original and is an enjoyable romp through the pride lands that will have families entertained with songs, drama and action, and just maybe have them roaring with laughter.
Everyone knows that the original “The Lion King” was an allegory for Shakespeare’s “Hamlet,” so it makes sense that the direct-to-video sequel “The Lion King 2: Simba’s Pride” would mirror the bard’s other play, “Romeo and Juliet.” The story follows Simba’s daughter Kiara who falls in love Kovu, an outsider who has been banished because he comes from Scar’s group of lions. The forbidden romance is frowned upon by both prides, but everyone has an opportunity to learn from their relationship.
The movie isn't quite perfect, though. Rowan Atkinson's absence as Zazu is a minor lament, while Andy Dick's casting as Nuka, while quite effective, does leave one to wonder why Disney picked such a controversial personality for a kid friendly movie. The "Upendi" sequence is a bit long and slightly out of place, while Zira's demise seems altogether too easy.
Still, the movie stands out, especially among Disney sequels, as extremely good. Matthew Broderick's mastery of the character Simba continues unabated here, while Neve Campbell and Jason Marsden take to their characters with equal skill. The real standout among the cast is Suzanne Plechette's voicing of Zira.
Her steely, cold-blooded voicing of the ruthless and calculating villain stands on equal footing with Jeremy Iron's voicing of Scar in “The Lion King”. One can only wonder what these two could have done if Scar and Zira had appeared together on screen. Sadly, we'll never know, as Ms. Plechette succumbed to cancer in 2008.
While nowhere as spectacular as the original blockbuster film, “The Lion King 2: Simba’s Pride” is the best of the Disney sequels nobody was asking for and a pretty good follow-up on its own. Longtime fans and newcomers alike are bound to enjoy the songs, comedy, drama and action presented here as the adventures of some of Disney's most beloved characters are treated with respect. Those looking for a roaring good time on family night are sure to find it here.

NGC 7635: Bubble in a Cosmic Sea
Image Credit & Copyright: Rolf Geissinger
Explanation: Adrift in a cosmic sea of stars and glowing gas the delicate, floating apparition left of center in this widefield view is cataloged as NGC 7635, the Bubble Nebula. A mere 10 light-years wide, the tiny Bubble Nebula was blown by the winds of a massive star. It lies within a larger complex of interstellar gas and dust clouds found about 11,000 light-years distant, straddling the boundary between the parental constellations Cepheus and Cassiopeia. Included in the breathtaking vista is open star cluster M52 (lower left), some 5,000 light-years away. Above and right of the Bubble Nebula is an emission region identified as Sh2-157, also known as the Claw Nebula. Constructed from 47 hours of narrow-band and broad-band exposures, this image spans about 3 degrees on the sky. That corresponds to a width of 500 light-years at the estimated distance of the Bubble Nebula.

Hubble Observes Exoplanet that Snows Sunscreen
NASA's Hubble Space Telescope has found a blistering hot planet outside our solar system where it "snows" sunscreen. The problem is the sunscreen (titanium oxide) precipitation only happens on the planet's permanent nighttime side. Any possible visitors to the exoplanet, called Kepler-13Ab, would need to bottle up some of that sunscreen, because they won't find it on the sizzling hot, daytime side, which always faces its host star.
Hubble astronomers suggest that powerful winds carry the titanium oxide gas around to the colder nighttime side, where it condenses into crystalline flakes, forms clouds, and precipitates as snow. Kepler-13Ab's strong surface gravity — six times greater than Jupiter's — pulls the titanium oxide snow out of the upper atmosphere and traps it in the lower atmosphere.

"In almost every article about the effort to pass what is primarily an enormous tax cut for corporations and the wealthy, you’ll see a line somewhere that says “Republicans fear that failure to deliver on taxes would be a political disaster,” or “If tax reform doesn’t pass, many in the party fear an all-out revolt in 2018.” That fear is real and powerful. But it’s worth considering exactly what they’re afraid of and why."

Suddenly we have an "epidemic" and a "national health emergency" instead of a "crime wave" and a "moral plague". Why? That's simple! Because this time around it's white folks who are addicted, leading ruined, hopeless lives, and dying left and right from overdoses. Otherwise there seem to be more similarities than differences compared to the 70s, 80s and 90s.
And, of course, cue the wraith of Nancy Reagan. Just say No! How people can be so goddamn stupid is a mystery that will probably never be solved.

InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) will conduct the first thorough “check-up” of Mars in more than 4.5 billion years, measuring its “pulse”, or seismic activity; its temperature; and its “reflexes” (the way the planet wobbles when it is pulled by the Sun and its moons).
By using sophisticated instruments – tools that can measure the vital signs of a planet – InSight will delve deep beneath the surface of Mars, detecting the clues left by the earliest stages of planetary formation.
Previous Mars missions have explored the surface history of the Red Planet. Mars has been less geologically active than Earth, so it retains a more complete record of its history in its core, mantle and crust. InSight will study the sizes, densities and overall structure of the Red Planet’s core, mantle and crust.
The lander will also measure the rate at which heat escapes from the planet’s interior, and provide glimpses into the evolutionary processes of all the rocky planets in our solar system, including Earth, and even those circling other stars.
You can send your name to Mars onboard the InSight lander! The deadline to get your Martian boarding pass is Nov. 1. To submit your name, visit: mars.nasa.gov/syn/insight

Mirach's Ghost
Image Credit & Copyright: Kent Wood
https://apod.nasa.gov/apod/ap171027.html
As far as ghosts go, Mirach's Ghost isn't really that scary. Mirach's Ghost is just a faint, fuzzy galaxy, well known to astronomers, that happens to be seen nearly along the line-of-sight to Mirach, a bright star. Centered in this star field, Mirach is also called Beta Andromedae. About 200 light-years distant, Mirach is a red giant star, cooler than the Sun but much larger and so intrinsically much brighter than our parent star. In most telescopic views, glare and diffraction spikes tend to hide things that lie near Mirach and make the faint, fuzzy galaxy look like a ghostly internal reflection of the almost overwhelming starlight. Still, appearing in this sharp image just above and to the left of Mirach, Mirach's Ghost is cataloged as galaxy NGC 404 and is estimated to be some 10 million light-years away.

A mysterious waterfall on the east coast of Iceland
As we wound our way up into the mountains on the east coast of Iceland, I saw this intriguing looking fall in the valley below. I pulled the car over and made the trek down to investigate. It actually turned out to be quite the beautiful little scene, in which I had all to myself. Unfortunately, I have no idea whether this stunner of a waterfall has a name or not, as it was stumbled across randomly.

https://en.wikipedia.org/wiki/De_re_metallica
(Latin for On the Nature of Metals [Minerals]) is a book cataloguing the state of the art of mining, refining, and smelting metals, published a year posthumously in 1556 due to a delay in preparing woodcuts for the text. The author was Georg Bauer, whose pen name was the Latinized Georgius Agricola. The book remained the authoritative text on mining for 180 years after its publication. It was also an important chemistry text for the period and is significant in the history of chemistry.

Scientists detect comets outside our solar system
(Team of professional and citizen scientists identifies tails of comets streaking past a distant star)
Jennifer Chu | MIT News Office
Scientists from MIT and other institutions, working closely with amateur astronomers, have spotted the dusty tails of six exocomets — comets outside our solar system — orbiting a faint star 800 light years from Earth.
These cosmic balls of ice and dust, which were about the size of Halley’s Comet and traveled about 100,000 miles per hour before they ultimately vaporized, are some of the smallest objects yet found outside our own solar system.
The discovery marks the first time that an object as small as a comet has been detected using transit photometry, a technique by which astronomers observe a star’s light for telltale dips in intensity. Such dips signal potential transits, or crossings of planets or other objects in front of a star, which momentarily block a small fraction of its light.
