How To Flirt (Successfully): A Pick-Up Guide by Nature’s Birds-of-Paradise

What’s your go-to move when you’re trying to flirt with someone? Are you the type that likes to make them laugh? Maybe you prefer the calm and collected approach, or maybe you go the direct route — no matter which you prefer, these all have one thing in common: the desire to impress. You might think that this is something that is unique to humans; however, there is one species that shares our desire to impress and takes it to the extremes: birds-of-paradise.

A large brain sits on a chair and looks at itself in the mirror, where it sees infinite reflections. The big brain is also surrounded by wiggly lines and eyes that are looking at the brain.

The Absurdity of Boltzmann Brains

13.8 billion years ago, our universe began. Then followed particles… then galaxies… then stars… then planets. One of these planets, formed 4.5 million years ago, witnessed the birth of our first human ancestors around 3.2 million years. Over these years, our brains evolved to understand emotions, communicate with others, create meaning out of trivial matters, and read online articles pondering their own existence. This seems to be an accurate summary of our existence, right?

Using Memory Techniques to Face the Monsters Under Our Beds

Nightmares are no rare phenomenon; every one of us has at some point been forced to confront the monsters under our beds. Medically, a typical nightmare is nothing to be afraid of. Even recurring nightmares are perfectly normal.

A thylacine walks out from the "History of Extinct Animals" book towards the modern world. The path the thylacine is walking on is lined with science-related objects, such as test tubes, mechanical gears, and magnets.

Science Fiction Becomes Fact: Bringing the Thylacine Back from Extinction

When I first watched Jurassic Park as a kid, I wasn’t at all worried about dinosaurs becoming a problem in the future. It was just science fiction after all, surely we can’t bring an extinct animal back to life! As time passed, the movie started becoming more of a cautionary tale and less fictional as the progress of scientific advancements continued to accelerate. In a world with climbing extinction rates yet remarkable technological innovations, it seems that the resurrection of extinct species is the solution to the extinction problem, but is it really a solution free of consequences?

Four colourful cartoon people stand in a line, each with an opening inside their chest displaying a set of chromosomes. The second person in line has an additional set of chromosomes and patches of a different colour on their body, representing chimerism.

Can we trust DNA? — Lydia Fairchild’s story

DNA is a unique biological molecule often referred to as the building block of life. In today’s society, identification of organisms or their relationships depends on DNA: For instance, determining someone’s identity from forensic evidence or conducting blood relation tests relies on an individual’s unique DNA sequence. This connection can be seen in our lives in situations like court cases and even as common as television shows! We trust the certainty of DNA to guide us in times of uncertainty.

Oh My God, I Know That Song!

You’re at a party. It’s pretty relaxed, people are chatting and you’re sitting in the living room with a friend. All of a sudden, “Last Friday Night” booms through the speakers. In a second, everyone is on the dance floor. “Yeah, we danced on tabletops, and we took too many shots / Think we kissed but I forgot / Last Friday night” Throwback after throwback plays, and by the end of the night your throat hurts from singing and you’re giddy from laughing with your friends. But what makes just one song capable of completely shifting the mood of so many people for an entire night? That’s a great question — it all has to do with the effect of nostalgia!

How Tabletop Physics can Uncover Secrets of our Universe

Many of the most awe-inspiring unsolved problems in physics deal with extremes of our universe —from the happenings of subatomic particles to those at the centres of black holes. Some of them tackle whether we can reconcile our existing understandings of these disparate regimes. Could we someday have a unifying theory of the physics of both the smallest and largest scales in the universe?

Let There Be Light: Optogenetics and the Brain

Imagine this: someone puts a light bulb in your brain. As the bulb switches on and off, it controls the activity of your brain cells. By targeting different cells, it might make you feel intense emotions, wake you up or put you to sleep, or even make you temporarily smarter.

Taking Flight: Aviators in the Animal Kingdom

Pterosaurs, birds, bats, and insects were the first to evolve the ability to fly, and in modern times, insects, birds, and bats are capable of true flight. So how exactly did this nearly 400 million year old process first start?

Start screen of a video game titled "The Fat Bear Tournament", portraying different bears as different characters. The subtitle prompts you to "choose your fighter". The winning bear, Otis, is shown in the centre between two other bears.

The Fat Bear Tournament

At this time of year, some animals are eating and sleeping more than usual to prepare themselves for the frigid weather ahead—and for their long winter ‘nap’. You see, these animals protect themselves in the harsh winter conditions by hibernating. Right now, you’re probably picturing a bear falling into a deep sleep throughout the winter, but there’s actually more to the story!
