The lead-crime hypothesis and its effect on modern-day society.

Lead. It’s probably not something you have thought of in recent years. Back in the 1920s, it was used in gasoline to reduce engine knock and in paints to speed drying. Of course, a couple of decades later, the toxic effects were undeniable and lead was banned in these products.

Lead exposure was linked to a series of neurological disorders including aggressivity, impulsivity, ADHD, and lower IQ. Interestingly, these are the same traits that are often associated with young criminal offenders. It begs the question:

Could lead poisoning cause high crime…

Does it seem like every attractive man you meet is rude, selfish, and totally uninterested in the well-being of others? Well, science agrees with you.

A study out of Brunel University in London has found that bodily attractiveness and egalitarianism are negatively correlated in males. This means that attractive men are less likely to believe that all people deserve equal rights and opportunities.

Through detailed questionnaires, the 125 participants were judged on their selfishness and attitudes towards social inequality. The study also used a “dictator” game, to determine their willingness to share wealth with others…

The current science of lucid dreaming and how you can learn to do it.

When I was a child, I was constantly plagued by nightmares. Nightmares of being chased by monsters or hunted by “the bad men”. The nightmares were relentless and I was scared of falling asleep. But, one night I realized that if I was killed in the dream, I would merely lay in darkness for a few moments before re-animating in a new dream (I wouldn't actually die).

This conscious awareness was the beginning of my lucid dreaming journey.

Slowly, I learned that I could make magical…

There’s more truth than you might think.

I am a sucker for a good science fiction TV show and, like many of you, I binge-watched the 6 episodes of Netflix’s german show “Biohackers” in a single day. How could you not? Glowing plants, underwater pills, see-in-the-dark eye drops, killer mosquitos — it’s fun to escape into this futuristic world.

But, how much of it is real?

The show talks about synthetic biology being the future of medicine, and arguably of all technology. …

When you think about cicadas, I’m sure you think about the loud screeching sound that this bug makes on a hot summer’s day. What you probably don’t know is that the cicada’s wings are self-cleaning and excellent at preventing microbial infections.

Well, some scientists from RMIT University in Australia decided to catch these bugs and figure out the secret of their wings. While a Ph.D. student probably spent 4 years of their lives studying the cicada, I am here to bring you the 5-minute version of the most interesting findings.

There are many different strategies animals and plants use to…

You’ve made your pitch. It was flawlessly executed (or at least you think so). But, a few days later you receive the dreaded message:

Your startup was not selected for funding.

More often than not, investors leave you scratching your head wondering what went wrong.

“I’ve worked so hard! This startup is my baby! Why do I keep hearing NO?”

Here are 5 reasons why investors might think your baby is ugly.

1. A product is not a business

You need a well thought out business plan. …

Don’t fake it, embrace it.

Everyone feels like an imposter sometimes, and that’s okay.

I think we’ve all had that feeling. You walk into a room and it feels like all eyes are on you. It’s like you can read their minds. They’re thinking: You don’t belong.

The others are so smart, polished, successful. You are nowhere near as good as these people. They are going to find out you are a fraud in 2-seconds flat. You are an imposter.

We’ve all heard the term “fake it ’til you make it”, but is that really the best advice?

You are not the smartest in the room, and that’s okay

5 steps to your dream job in a male-dominated workplace.

“Please let me help,” I told them. “I want to learn.”

During my first year working as an engineer for a large corporation, I was assigned to a tech analysis project with three of my male colleagues. My manager needed another engineer to learn the complex analysis method and he picked me! I was so excited to start.

I told the project lead to call me anytime the team works on the project. I wanted to learn as much as possible.

“Of course,” the project lead agreed. “You will be fully involved.”

A few days later, I walked by the lead’s office to find the entire team (except for me) working…
