We track a hungry but determined Polar Bear as it seeks to ambush a plump Seal. With the odds stacked against it, this scrawny looking Bear will need to pull off an amazing manoeuvre if it's to get a well earned meal.

Superacid vs. Tangerine

The classical definition of a superacid is any acid with an acidity greater than that of 100% pure sulfuric acid (H2SO4). In highly concentrated solutions, the Henderson-Hasselbalch equation used to define the pH scale breaks down due to large variations in the activity coefficients. In order to measure the acidity of very concentrated solutions, a similar metric known as the Hammett acidity function (H0) was introduced. Using this scale, 100% sulfuric acid has an H0=-12.

The acid used in this GIF is chlorosulfuric acid (HSO3Cl), which has an H0=-12.78, therefore making it a superacid. It reacts violently with the water in the tangerine skin to yield sulfuric acid and hydrogen chloride (HCl) gas. The sulfuric acid then reacts with the sucrose of the tangerine via an intense exothermic dehydration reaction to produce carbon in its black graphite form.

For privacy focussed peeps

Today, Signal outlined how it plans to use SGX as a sort of middleman between its servers and your phone’s contacts, taking it one step further from knowing anything about you. Your contacts will pass through this secure enclave for processing and will disappear afterward. And going forward, users will be able to double-check that Signal’s open-source code hasn’t been altered in a way that would instruct the servers to store contact data, and the contacts are only temporarily held in the SGX. If all the testing works out, Signal wouldn’t ever “see” your contacts, and the code in the SGX would be unalterable by Signal’s team.

Not a bad concept

If cars become fully autonomous, then the traditional design language that has held up for decades goes out the window. Engineers and automakers are already beginning to rethink the vehicle’s interior, removing steering wheels, adding bookshelves, and positioning car seats to face one another. Rather than be left behind, Michelin is contributing to this effort through its reinvention of its tires, both in form and function.

Horton says that improved features are a result of better packaging of the lithium-ion battery, not necessarily the chemistry. But eking out range for city customers was important.

“We wanted to make sure that we could meet the needs of every transit agency in America,” said Horton. City buses can often run 40,000 miles a year for 12 years.

While electric buses might not be as attention-grabbing as Tesla luxury electric cars, buses could become electrified the fastest. “Electric buses will be the market to watch in terms of adoption,” said Horton. “The transition [to electric] will happen far, far faster than with passenger cars.”

Freezing Bubble

A soap bubble exposed to very cold temperatures (-25°C/-13°F) will quickly freeze as ice crystals form and coalesce into an icy sphere. The intricate detail of the expanding crystals can easily be seen as the liquid water transitions to its solid state.

The Cassini mission’s epic 13-year exploration of Saturn is coming to a close. On Sept. 15, the spacecraft will make a planned plunge into the atmosphere of Saturn in order to protect pristine icy moons that warrant future exploration. As the mission nears its end, team members reflect on this historic, international collaboration.
