Like Britain, Seattle Also Takes It As A Sign Of Weakness To Use An Umbrella

UBC undergrad discovers four new planets

Graduating on Monday, astronomy student Michelle Kunimoto got a shout-out from William Shatner for her discovery.

When astronomy honour’s student Michelle Kunimoto graduates on Monday, she’ll do so already holding the honour of being a galactic pioneer with distinction.

The 22-year-old University of British Columbia undergraduate has discovered four new planets in the Cygnus (Swan) constellation, known as “exoplanets” because they’re outside our solar system.

“I got interested in exoplanets from Star Trek,” she told Metro in an interview in UBC’s physics department. “The whole theme of Star Trek, curiosity and exploration, is really important for the long, long, long term. We want to answer the age-old question: Are we alone?”

She spent months poring through 400 different data samples from the Kepler space telescope, which captures the curves of light from distant stars. Sudden dips in their light can correspond to planets passing in front of them.

Kunimoto likened her method to trying to hear one quiet voice in a crowded room full of loud talkers. But when she first noticed the faint but tell-tale dip, she didn’t allow herself get excited.

“I had to be very careful,” she explained. “I ran them through a lot of tests, but the more tests I ran, the more confident I felt.

“When they all passed the right tests, and I had these four planets remaining, that was really exciting!”

The planet she’s most enthusiastic about is called Kepler Object Of Interest 408.05, which she nicknamed “Warm Neptune,” because it’s roughly the size of its namesake planet, but is within the distance needed for the warm, Earth-like atmosphere needed to host life. It’s 3,200 light years from Earth.

Technically, what she found are still considered “planet candidates” until they can be independently confirmed, but for her UBC supervisor the results are clear.

“It’s rare that you have that ‘Eureka!’ moment any more,” astronomy professor Jaymie Matthews told Metro proudly. “Michelle’s discovery was time-consuming, and she’s done this for only 400 out of 150,000 light curves.”

But will Kunimoto’s “Warm Neptune” — located within what Matthews dubbed the “Goldilocks” zone of planets that are neither too hot nor too cold to support life — potentially be home to intelligent life?

“You can bet that once the results are confirmed and more widely disseminated, the Search for Extraterrestrial Intelligence Institute will put KOI-408.05 on their list of higher-priority targets to monitor,” Matthews said. “If there is life and signals we could eavesdrop on, these are the places they’d be coming from.”

On Saturday, Kunimoto got a shout-out before a large UBC audience from Star Trek star William Shatner, who praised her discoveries on stage. “I was really honoured!” she said. “That was completely unexpected, my face was going red.”

It’s amazing how crafty humans are! [Via @veritablehokum]

"Lost Cities" Discovered In Libya

The Garamantes were an ancient civilization, in what is today Libya, on the African northern coast.  Unfortunately for their legacy, most of what we knew about them comes from their enemies, the Romans. Unsurprisingly, the Roman accounts described the Garamantes as “barbaric nomads and troublemakers on the edge of the Roman Empire.” This view of the Garamantes as a minor, annoying tribe is being overturned by recent digs. In 2011, a team of researchers led by archaeologist David Mattingly from the University of Leicester discovered more than 100 fortified farms, towns, and villages with castle-like structures in Libya that date from 1 CE to 500 CE. The Garamantes operated a trans-Saharan trade, and were even pioneers at building oases! Hardly the “barbaric nomads” the Romans unfairly called them.

At what point did Britain and France stop always being on the brink of war with each other?

He [Wilhelm II] returned to Europe [from his tour of the Holy Land] in autumn to find Britain on the point of war with France over a solitary little fort in the middle of nowhere in southern Sudan called Fashoda. Fashoda was the point where French plans to dominate Africa east to west, from Dakar to Djibouti, intersected with British plans to connect South Africa to Cairo.

A French troop occupied the fort; a British one sat outside it – very politely. The two commanders took tea together.

The quote is taken from George, Nicholas and Wilhelm: Three Royal Cousins and the Road to World War I by Miranda Carter.

Chlorosulfonation of an imidazole derivative with chlorosulfonic acid.

Why is this a special thing? Chlorosulfonic acid reacts with water explosively forming sulfuric acid and hydrogen chloride. So when I added 200 g of a compound to 500 cm3 of chlorosulfonic acid, a highly exothermic reaction happened and immediately and a highly acidic fog formed in the flask as the reactants contacted each other.

Important note when working with chlorosulfonic acid: NEVER WASH ANYTHING WITH WATER WHAT CONTAINS A RANDOM LIQUID, since if its chlorosulfonic acid, it could blow a highly acidic solution on your labcoat/hands/face. And always pour chlorosulfonic acid and reaction mixtures that contain this chemical on large excess of cracked ice to avoid serious problems.

P.S.: always wear proper PPE.

Thousands of years of human breeding transformed wild species into the domesticated varieties we enjoy every year. Most of these foods were originally found in the Americas. Some of my favorite details:

The original domesticated carrots were purple. Carrots were bred to be orange by Dutch farmers in the 17th century, and then used as a political symbol of the ruling family - the House of Orange.

The ancestors of pumpkins were mainly eaten by mastodons and giant sloths - they were too bitter for smaller animals to stomach.

Turkeys were bred to have white plumage so their skin would be more uniform in color.

Happy Thanksgiving!!
