What an underground nuclear explosion looks like

Recent aerial photo of the crater made in the wake of the nuclear blast.

One this day, 53 years ago, the Lawrence Livermore National Laboratory detonated a thermonuclear device 194 meters below the Nevada desert. Why? Well, the government at the time thought blowing up a nuclear bomb underground sounded like a good idea if you want to excavate a mine. It’s a lot quicker than drilling with a lot machines. After all, mines are made using thousands of tonnes of dynamite. Why not take a shortcut and nuke the damn thing. The problem, of course is radiation. But how can you have people work in a mine if it’s contaminated with radiation, right? The logic escapes me as well.

Is there really a mathematical formula that predicts happy relationships?

Love equation

In a recent TED talk, Hannah Fry outlines a mathematical formula that predicts long-lasting relationships. In her recent book, The Mathematics of Love, she discusses the findings of psychologist John Gottman who studied hundreds of couples over many years to find out what sets apart the happy couples from the miserable. Gottman than enlisted the help of a mathematician who correlated all the data the psychologists gathered and came up with an empirical formula that seems to predict if a couple will be happy together.

Nitrous oxide, commonly known as laughing gas, is a simple chemical composed of two nitrogen atoms and one oxygen atom (N2O). Despite being used as an anesthetic since the 1800s, the effects it has on the brain are not well understood. In a new study published in this week in Clinical Neurophysiology, MIT researchers reveal some key brainwave changes caused by the gas.

Reddit user Wolfhole took a spectacular picture of a pink katydid, also known as a bush cricket. I’m not sure exactly what species this is, but according to Twisted Sifter, it’s an Oblong-winged katydid or Amblycorypha oblongifolia. While green is by far the most common color; pink, yellow and orange colorings can occur but are far more rare. While they are not truly dangerous,

A simple sniff test might diagnose autism in toddlers

autism sniff test

Children with autism spectrum disorder do not react as well to pleasant or foul smells compared to non-ASD children. Previously, autistic toddlers were found to have a dampened response to sight, sound and touch. For their study, the researchers at the Weizmann Institute of Science in Israel used a novel technique to gauge the smell response in both ASD and control groups, with 81% accuracy. The test is unobtrusive and doesn’t require a personal account from behalf of the children – something that can be difficult to do with autistic children, who more often than not are highly uncommunicative. If the test can survive the test of time and other trials, it could very well be used to diagnose autism.
