2:00 PM | If you don’t succeed, try again: Timed tests using specs grading
Six weeks into the specifications grading experiment, one of the most positive things to emerge from the class is a modified model of timed testing that focuses on student choice and a revise/resubmit cycle that lowers student stress. Here's how it's working for me.

12:09 PM | Poliovirus replication – many generations per cell

9:29 PM | Wealth Study: One Out of Every 22 New York City Residents Is A Millionaire
Last year, Spear’s Wealth Management Magazine joined forces with consulting firm WealthInsight to figure out which global cities had the highest proportion of millionaires. According to their analysis, approximately 389,100 New York City residents have a net worth greater than $1 million. With a total population of just over 8.4 million, that means that 4.63% of the people living in the “Big Apple” are millionaires – roughly 1 out of […]

5:26 PM | First space taxi successfully returns from test flight
Can you imagine we’d ever be discussing taxis going into outer space? Well, an experimental spacecraft has returned to Earth after a successful mission. ESA’s Intermediate Experimental Vehicle (IXV) has successfully returned home after a 100 minute mission through the atmosphere. The initial launch was postponed due to some launch problem, but finally it took off on a Vega rocket from Kourou in South America. The total flight lasted about 100 minutes. It traveled 256 […]

3:38 PM | Here's what happens when hydrophobic sand is dropped in water
The material in the video looks like normal sand and, as far as we can tell, feels like regular sand. But it sure doesn't act like it, as you can see in this episode of BBC's iconic quiz show QI, from 2012.The experiment starts out normally enough, with host Stephen Fry sprinkling some red sand into a glass of water, where it forms a thin, floating layer. But then he shoves his finger into the water and instead of going right through the sand, the grains form a barrier for his skin and he […]

And they’ve also renamed it to mark the upgrade - it's now called ‘systemic exertion intolerance disease’, or SEID for short.It's pretty huge news for people affected by the mysterious illness, which has often been brushed off by clinicians as simply being “exhaustion” or a psychological, rather than physical, condition, […]
