Humans Have Killed Off One Less Species Than Originally Thought

As a species, humans are pretty awful for the rest of the things living on this planet. But as it turns out you can take one less creature off the extinction list: Allonautilus scrobiculatus isn’t all gone, just quite hard to find.


If Humans Never Existed, The World Would Have More Mammals

There aren’t many large mammals around anymore in, most of the world. That’s mostly because one mammal species — Homo sapiens — has taken a heavy toll on its competition. Now, a team of researchers demonstrates what would have happened to the world’s megafauna if humans had never existed.


This Is How Sewer Rats End Up In Residential Toilets

While Australians may be used to checking for spiders under their toilet seats, Americans could find themselves with another unwanted visitor in their toilet bowls. It sounds like an urban legend, but rats actually do manage to crawl up from the sewers and into unsuspecting residential toilets. In Portland, Oregon, one pest control company says it gets ten to 15 calls a year for rats in toilets, and it’s easy to speculate that the numbers are higher in cities like New York.


First Complete Octopus Genome Will Unlock Cephalopod Secrets

Scientists have finished sequencing the first complete octopus genome, and it’s a big step toward unravelling many cephalopod mysteries, including the basis of their unusual intelligence and unmatched camouflage abilities.


A Child In Los Angeles Has The Plague

A Los Angeles County child is recovering from the plague, and public health agencies are searching the wilderness for the source of the infection.


Deep Sea Electricity May Have Kickstarted Life On Our Planet 

Curious about how life got started on Earth 3.8 billion years ago? Here’s a thought: Why not recreate ancient hydrothermal vents in the lab, and see if they produce enough juice to power a lightbulb? That, at least, is what a bunch of scientists at the Jet Propulsion Lab decided to do — and the electrifying results are helping unravel life’s origin story.


Venomous Frogs Use Deadly Face Spines To Slay Their Enemies

It’s common sense that you shouldn’t try to eat a poison dart frog. But you probably don’t want to go anywhere near one of these adorable little suckers, which use the tiny, bony spines on their faces to jab threatening animals with a venom more potent than that of a deadly pit viper.


Scientists Turn Skin Cells Into Brain Cells, Using Alzheimers Patients

You are looking at freshly-made human neurons, or brain cells. But they used to be common skin cells. And their existence could change how we treat Alzheimers.


Scientists Have Grown Human Serotonin Neurons In The Lab

This flurry of neon colour above may look like a blurry photography of a particularly wild party, but in fact it’s the first ever sample of human serotonin neurons to be grown in the bottom of a Petri dish.


What It's Like To Lose Your Sense Of Smell

Losing your sense of smell takes away more than scents and flavours — it can fundamentally change the way you relate to other people.
