Hate itchy mosquito bites? Building up an immunity only requires about 15,000 bites per year

Meet Steve Schutz. Some might say he’s very dedicated to his work. But others would call him downright crazy. You see Steve works in an insectarium, a place where mosquitos are born and raised. And to ensure its residents are well-fed and propagate, he serves up his bare arm once a week for dinner.

As a result, after a feeding the 50 red welts on his lower arm barely even register as a slight tingle since Steve has built up an immunity to the mosquito’s saliva…

The Higgs Boson is kind of a big deal. If it does exist, it could provide a key to unifying the standard and quantum models of physics. But what is a Higgs Boson, what does it do, and how does it work? With the help of this animated short, UCI physics professor Daniel Whiteson breaks down the basics of this mysterious particle (or is it a field?) in a way even your parents can understand.

Thinking in a different language affects how you make decisions

The languages you know affect how you think.

Back in 2002, psychologist Daniel Kahneman won the economics Nobel Prize for showing that human beings don’t have a really good intuitive grasp of risk. Basically, the decisions we make when faced with a risky proposition depend more on how the question is framed than on what the actual outcome might be.

The classic example is to tell a subject that there’s going to be a disaster. Out of 600 people, she has a chance of saving 200 if she takes x risk. If she doesn’t take the risk, everybody dies. Most people will take the risk in that scenario, but if you present the same situation and frame it differently—”If you take this risk, 400 people will die”—the decisions suddenly flip in the other direction. Nothing has changed about the outcome. But everything has changed in terms of how people feel about the decision they have to make. This is the kind of thing that matters a lot to economics because it helps to explain why economic behavior in the real world isn’t always as rational and self-interested as it is in theory…

Girl cuts hair to buy house

It took four hours every week to wash her hair and an hour and a half to brush every day

There are certain drawbacks to having a five-foot-long mane of hair. Twelve-year-old Natasha Moraes de Andrade of Rio de Janeiro, Brazil, was proud of her hair, but it took hours to wash and comb it. Her family couldn’t turn on fans for fear of getting it caught. And riding a bicycle was out of the question. Still, getting her hair cut was a difficult decision.

‘I cried at first when I was at the hairdressers to get it cut,’ she says.

‘I was afraid I wouldn’t like it, and I was also scared I might not get the money I wanted for it…
