Reactivating Visual Memories is a New Alternative to 'Practice Makes Perfect'
A new Tel Aviv University study finds that brief memory reactivations can replace repeated extensive practice and training -- commonly known as "practice makes perfect" -- as a basis of procedural learning.

The Bilingual Brain Calculates Differently Depending on the Language Used
The study documents for the first time, with the help of brain activity measurements and imaging techniques, the demonstrable cognitive "extra effort" required for solving arithmetic tasks in the second language of instruction. The research results clearly show that calculatory processes are directly affected by language.

Which is your favorite Cassini picture of Saturn?
Take your time scrolling through these stunning pictures, and then...which is your favorite? Mine are the ones entitled Backlit by the Sun. But I know I will change my mind again and again and again.
These photos are architectural, geometrical, scientifically photographic, other worldly (really?), hard to imagine, yet utterly real.
Tomorrow is the day that Cassini flies toward its fiery death on Saturn. I have attached as the first comment (it also appears at the end of the photographs), a lovely video narrated by the beautiful voice of science writer Denis Overbye. How appropriate he should narrate the description of how Cassini's brilliant life will end. _"This is Cassini. Over and out. Bye."

Hubble Captures Blistering Pitch-Black Planet
This illustration shows one of the darkest known exoplanets— an alien world as black as fresh asphalt—orbiting a star like our Sun. The day side of the planet, called WASP-12b, eats light rather than reflects it into space. The exoplanet, which is twice the size of Jupiter, has the unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere. The temperature of the atmosphere is a seething 4,600 degrees Fahrenheit, which is as hot as a small star.
The day side hordes all the visible light because it always faces its star. The planet orbits so close to its host that it has fixed day and night sides. WASP-12b is about 2 million miles away from its star and completes an orbit once a day. The night side is much cooler, with temperatures roughly 2,200 degrees Fahrenheit, which allows water vapor and clouds to form. A swirl of material from the planet’s super-heated atmosphere is spilling onto its star.
This oddball exoplanet is one of a class of so-called "hot Jupiters" that orbit very close to their host star and are heated to enormous temperatures.
Sept. 14, 2017: NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet's unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere.
The oddball exoplanet, called WASP-12b, is one of a class of so-called "hot Jupiters," gigantic, gaseous planets that orbit very close to their host star and are heated to extreme temperatures. The planet's atmosphere is so hot that most molecules are unable to survive on the blistering day side of the planet, where the temperature is 4,600 degrees Fahrenheit. Therefore, clouds probably cannot form to reflect light back into space. Instead, incoming light penetrates deep into the planet's atmosphere where it is absorbed by hydrogen atoms and converted to heat energy.
"We did not expect to find such a dark exoplanet," said Taylor Bell of McGill University and the Institute for Research on Exoplanets in Montreal, Quebec, Canada, lead researcher of the Hubble study. "Most hot Jupiters reflect about 40 percent of starlight."
But the planet's nighttime side is a different story. WASP-12b has a fixed day side and night side because it orbits so close to the star that it is tidally locked. The nighttime side is more than 2,000 degrees Fahrenheit cooler, which allows water vapor and clouds to form. Previous Hubble observations of the day/night boundary detected evidence of water vapor and possibly clouds and hazes in the atmosphere. WASP-12b is about 2 million miles away from its star and completes an orbit once a day.
"This new Hubble research further demonstrates the vast diversity among the strange population of hot Jupiters," Bell said. "You can have planets like WASP-12b that are 4,600 degrees Fahrenheit and some that are 2,200 degrees Fahrenheit, and they're both called hot Jupiters. Past observations of hot Jupiters indicate that the temperature difference between the day and night sides of the planet increases with hotter day sides. This previous research suggests that more heat is being pumped into the day side of the planet, but the processes, such as winds, that carry the heat to the night side of the planet don't keep up the pace."
The researchers determined the planet's light-eating capabilities by using Hubble's Space Telescope Imaging Spectrograph to search in mostly visible light for a tiny dip in starlight as the planet passed directly behind the star. The amount of dimming tells astronomers how much reflected light is given off by the planet. However, the observations did not detect reflected light, meaning that the daytime side of the planet is absorbing almost all the starlight falling onto it.
First spotted in 2008, WASP-12b circles a Sun-like star residing 1,400 light-years away in the constellation Auriga. Since its discovery, several telescopes have studied the exoplanet, including Hubble, NASA's Spitzer Space Telescope, and NASA's Chandra X-ray Observatory. Previous observations by Hubble's Cosmic Origins Spectrograph (COS) revealed that the planet may be downsizing. COS detected material from the planet's super-heated atmosphere spilling onto the star.
The results will appear online Sept. 14 in The Astrophysical Journal Letters.

But while Sessions and his boss can ice the reform movement in Washington, D.C., the same policy consensus continues to drive change at other levels of government to massive effect. When a state like California changes its approach to crime and punishment, for example, it invites an eighth of the U.S. population to greet the dawn Trump wants to cancel.

I wanted a new Lego Millennium Falcon. Without further ado, here it is. Not quite the new UCS model, but my first Star Wars Lego MOC in, umm... close to 37 years, or so.
I once said I won't post any MOC's because I don't build, what I photograph is straight from the boxes. But, you know, I couldn't resist. This took seven bricks to complete.

September 15, 2017: Cassini's Final Plunge into Saturn's Atmosphere
The international Cassini mission reaches its dramatic finale this Friday by plunging into Saturn’s atmosphere, concluding 13-years of exploration around the ringed planet, so ending the mission just one month shy of its 20th launch anniversary.
Having expended almost every bit of the rocket propellant it carried to Saturn, scientists will deliberately plunge Cassini into the planet on Sept. 15.
Why? To ensure Saturn's moons will remain pristine for future exploration: in particular, the ice-covered, ocean-bearing Enceladus, but also Titan, with its intriguing pre-biotic chemistry.

Because Saturn is so far from Earth, Cassini will have been gone for about 83 minutes by the time its final signal reaches the Deep Space Network's Canberra station in Australia on Sept. 15, 2017.
The current predicted time for loss of signal on Earth is 4:55 a.m. PDT (7:55 a.m. EDT) on Sept. 15, 2017. This time may change as Saturn's atmosphere slows Cassini during each of the final orbits.

Astronaut Moments with NASA astronaut Mark Vande Hei
Vande Hei and his crewmates, Joe Acaba of NASA and cosmonaut Alexander Misurkin of the Russian space agency Roscosmos, launched on the Russian Soyuz MS-06 spacecraft on Sept. 12. They are scheduled to return to Earth in March 2018. The crew members will continue several hundred experiments in biology, biotechnology, physical science and Earth science currently underway and scheduled to take place aboard humanity's only permanently occupied orbiting lab.
Mark T. Vande Hei was selected by NASA in 2009. From Falls Church, Virginia, Vande Hei earned a Bachelor of Science in Physics from Saint John's University and a Master of Science in Applied Physics from Stanford University. He was commissioned in the U.S. Army through the ROTC program and served as a combat engineer. In 1999, he became an assistant professor of physics at the United States Military Academy in West Point. He is currently assigned to Expedition 53/54, which is planned to launch in August 2017.
