Animation Explains How Viruses Attack Our Cells To Make Us Sick

Staying healthy is a lot like medieval warfare. Cells vs viruses. There are cells defending their castles and viruses trying to break through. If a sneaky virus manages to attack a cell, the cell fights it and notifies all the other castles about what to build to defend it.


Look At These Beautiful Little Corals Grown Like Ice Blocks In A Lab

Coral sex is a wonder to behold. On a summer night, always around a full moon, corals somehow all know to release billions of sperm and eggs into the sea, turning the water into a pink miasma of sex. This spawning relies on precise environmental cues, which could get scrambled in climate change. That’s why researchers are trying to get them to spawn in the lab.


Scientists Have Cloned Embryos From Adult Cells For The First Time Ever

Ever since Dolly the sheep was cloned eighteen years ago, scientists have been trying and failing to use that same technique to create cloned human embryos from adult cells. Now, they have finally succeeded, in what could a major step toward personalised organ transplants and other therapies that rely on a pool of stem cells.


Gardener Claims He Hasn't Watered This Flourishing Biosphere Since 1972

If you can’t raise a plant to save your life you know the appeal of terrariums, which can sustain themselves for months on end without being watered. But a retiree in the UK says he sealed up his bottle garden in 1972 — and hasn’t watered it since.


What Happens To Bacteria In Space?

In the otherwise barren space 350km above Earth’s surface, a capsule of life-sustaining oxygen and water orbits at 27,000km/h. You might know this capsule as the International Space Station (ISS), currently home to six humans — and untold billions of bacteria. Microbes have always followed us to the frontiers, but it’s only now that scientists at NASA and elsewhere are seriously investigating what happens when we bring Earth’s microbes into space.


This Amoeba Eats Human Intestines, Cell By Cell

It might look positively adorable in this image, but don’t be fooled: this pathogen, known as Entamoeba histolytica, eats human intestines alive, cell by cell.


Nanoparticles In Consumer Products Could Be Damaging Your DNA

Masses of products — from cosmetics to clothing — now contain nanoparticles, to kill microbes, lengthen shelf life or provide other wonderful properties. But new research from MIT and Harvard suggests they could also be damaging your DNA.


First Ever Lab-Grown Muscle That Can Heal Itself In Living Creatures

Anyone who’s ever torn a muscle will be grateful for that fact that the fibres can repair themselves. But now researchers have developed lab-grown muscle that can achieve the exact same thing.


4 Ways Tiny Microbes Changed Life On Earth Forever

This is the microbes’ world — we just live in it. Throughout the history of Earth, microbes have radically reshaped life on the planet, from creating the very air we breath to wiping out almost all life on Earth. Don’t underestimate the power of tiny, tiny microbes populating the Earth trillions of times over.


Stem Cell Researchers Just Figured Out How To Create New Embryos

A team of researchers from the University of Virginia just made scientific history: They figured out how to turn stem cells into full blown fish embryos. In other words, scientists can now control embryonic development, a key to being able to grow organs and even entire organism from stem cells.
