Watch Two Sex Educators Show It's Safe To Make A Dental Dam From Plastic Wrap

Sex educators Megara Bell and Brian Flaherty (both from the Boston group Partners in Sex Education) are a little stiff on camera, but the message of their delightful science demonstration (with controls!) is clear. If you’re in a pinch, microwavable plastic wrap is impermeable to viruses and you can use it to fashion a MacGyver-like dental dam.


A $25 Blood Test Could Detect Every Virus That's Ever Infected You 

Every time a virus gets you sick, your immune system keeps a record. This essentially becomes a kill list that lets your body recognise and readily dispatch of any virus that tries to invade again. Scientists have now created $US25 test blood test that prints out this list — an easy and cheap way to find out every virus that’s ever made you sick.


UV Water Purifiers Are Bullshit

To achieve its claimed ability to remove pathogens, water going into CamelBak’s new UV purifier must first be cleaned by a filter from a rival manufacturer. And that rival product is cheaper. That’s according to CamelBak’s own lab testing. And its not the only water treatment technology that’s incapable of performing as claimed.


How Viruses Hide Inside Your Eyeballs, Even When You're No Longer Sick

Last week brought the horrifying news that the Ebola virus can live in the eyeballs of survivors, even after it’s been eliminated from the rest of the body. It shouldn’t have been a surprise, though. Viruses have always hidden in parts of our bodies you’d never expect. In fact, we’re all walking virus reservoirs.


Doctors Just Discovered The Ebola Virus Can Live Inside The Eye

After working as a doctor in an Ebola-stricken nation, Ian Crozier felt like he had something in his left eye. He was right: a live, replicating reservoir of the Ebola virus.


How A Virus Can Make Water Boil Faster

Here are some things that won’t make water boil faster: watching the pot, adding salt. And here’s something that does: nano-structures made from plant viruses, which subtly alter the physical properties of bubbling water.


The US Will Stop Funding Research Into Making Mutant Super Viruses

Should scientists be allowed to create mutant viruses deadlier than natural ones? The White House waded into this controversy today with a surprising announcement to cut all funding to such studies, pending a thorough review of this risky research.


We Only Just Discovered This Super-Common Virus That's Probably Inside Of You

Today, scientists report the discovery of an incredibly common new virus that lives inside human gut bacteria. It’s called crAssphage (more on the name later!), and it’s about six times more abundant than all other known bacterial viruses put together. How did we miss it for so long?


This Pacemaker Is Made By Injecting A Virus Right Into A Pig's Heart

Pacemakers are — even at their tiniest — intrusive bits of metal wired into the heart. But now scientists have come up with something completely different: a “biological pacemaker” in a pig made by reprogramming the heart’s own cells with a modified virus carrying a specific gene.


The Dangers (And Benefits) Of Designing Mutant Super Viruses

Take an already deadly flu virus like H1N1 — killer of an estimated 284,000 people — and imagine how to make it worse. How about a virus impossible for your immune system to detect? This is not just a thought experiment — a controversial Wisconsin lab known for concocting dangerous mutant viruses has actually created such an immune-evading H1N1 virus.
