Spike the Spice: Synthetic Tongue Rates Chillies

Spike the spice

A gel-based synthetic tongue might let the steam off human chilli tasters, as it can determine the level of spice, from the mild bell pepper to peppers like the Carolina Reaper, which taste like pain and regret. Chillies have been the stars of “hot” trends, from the One Chip Challenge […]

These often large, lacy fronds lend themselves nicely to watercolor paintings and tricep tattoos alike. Thoreau said it best: “Nature made

Pigeon’s Mysterious “Compass” Organ Might be Present in Their Inner Ear

Pigeon

How does it feel when you’re stuck at a crossroads, with no idea where to turn? You hit navigation on Google Maps and find your way. Sadly, pigeons are not as proficient at using GPS. What’s even the point of using such tech when you’ve got a built-in compass up

A pocket watch is being swung right in front of your eyes. Your eyes track it, and a soothing voice asks you to “sleep”. A snap later, you lose your senses and become a puppet of the hypnotist. Movies portray it as a surreal experience; in reality, it’s far worse.

Ancient Pet “Pawps”: How Prehistoric Humans Bred Dogs

Dog skull

Wolves found food scraps. They ate those. They found the coveted “infinite food glitch.” That’s how wolves grew closer to prehistoric humans, before eventually getting tamed. However, how did we come from wolves to pugs? How did humans breed them to gain such variety? Most of the credit goes to

The Anti-Cyborg: How Scientists are Building Computers That Run on Human Brain Cells

Pluripotent Stem Cells to GABAergic Neurons

The human brain has the storage capacity of 2.5 million gigabytes, or 2.5 petabytes, and consumes just enough power to light an LED. To put it in perspective, around 20 watts of power is sufficient for a memory that can store 3 million hours of video. Now, scientists are trying

Learning a New Language Keeps the Brain Young

Hello in different languages

Solve puzzles, eat your veggies, and keep that streak intact on Duolingo! New research suggests that learning new languages can slow brain aging and prevent cognitive decline. A study spanning 27 European countries and involving over 80,000 individuals showed that multilingualism reduces accelerated biological aging by 50%.  Multilingualism has long
