A computer made from water droplets

If you thought the computer devised out of soldier crab swarms was cool, wait till you hear what scientists at Aalto University managed to make. In a recently published study, the researchers built a hydrophopic set-up through which they channeled water droplets, and in the process encoded information, practically building a computer. The researchers used the term “‘superhydrophobic droplet logic” to describe

Is it better to run or walk in the rain to stay as dry as possible? A lifelong physics question

You just got out of the office, looking to head home to a soothing dinner, only to find that it’s raining cats and dogs outside – and you forgot your umbrella of course. Do you walk or run to your car to stay as dry as possible? It might sound trivial, but this is a question that has gained a

Water doesn’t prevent dehydration according to EU officials

It’s a fairly known fact that the adult human body is typically 60% made out of water. Hence comes the common sense that if you happen to become dehydrated, you have to drink water to get well. It’s an instinctual event, this is why our body developed the essential mechanism of thirst. The European Food Standards Authority (EFSA) seems to think

Icy moon rains water on Saturn

For the past 14 years, astronomers have been scratching their heads trying to find out just where does the water in Saturn’s upper atmosphere comes from; now, ESA’s Herschel space observatory has solved that mystery – the water is expelled from Enceladus, one of the planet’s moons. Enceladus is eliminating about 250 kilograms of water every second through a set

Enormous water reservoir found in space is bigger than 140 trillion earth oceans

Astronomers have discovered the largest body of water so far known, a reservoir of water floating in space around a ancient distant quasar,  holding 140 trillion times the mass of water in the Earth’s oceans. Remarkably enough, the find was dated as being 12 billion light years away, only  1.6 billion light years farther from the Big Bang. “Since astronomers

“Super sand” is five times more purifying than regular one. Turns toxic water into drinkable water

It’s a bird! It’s a plane! No, it’s super sand! *tadam Researchers from Rice University have managed to develop a new kind of filtering sand, dubbed “super sand”, which has five times the filtering properties of regular sand. The advancement could provide an indispensable, cost-effective solution for the current water crisis in developing countries where millions of people do not

The moon’s interior is wet, amazing new study shows

Two years ago, NASA’s LCROSS probe was looking for signs of water when it smashed into Cabeus crater at the moon’s south pole. It turned out to be one of those incredible fail moments, since not only did researchers found there was water from the data transmitted back, but that the surface was actually wetter than the Sahara Desert. One

The PeePoo bag: don’t poop where you eat

Nairobi, Kenya is home to one of the world’s biggest slums, more than one million people living in subhuman conditions in the African state capital. I’ve seen and read a lot of reports from there, and other African states alike, and the situation is indeed dire. Imagine having nothing to eat – now imagine having to poop the scraps of

Water droplet bouncing on a Superhydrophobic Carbon nanotube array

This is the best video I’ve seen in quite a while ! Don’t let the fancy title fool you, the video explains what’s happening so it’s really easy to understand what’s happening.

Stunning variety of sea life found in Antarctica

The British Antarctic Survey (BAS) published some quite awesome pictures showing that Antarctica isn’t the lifeless frozen wasteland most people believe it to be; ice fish, octopus, sea pigs, giant sea spiders, rare rays and gorgeous basket stars all thrive in the extreme temperatures in Antarctica’s waters. Well, thrive is perhaps a too strong word, but they’re doing just fine

Amazing video of a drop of water in super slow motion portrays surface tension

Well, these guys explain it way better than I could, so watch the video, even if you are familiarized with surface tension. The super slow-mo frames are absolutely wonderful !

Water and fog found on Titan, Saturn’s moon

As I was writing in a previous post, Titan is quite unique, in that aside from our planet it’s the only place in our solar system where significant quantities of liquid are to be found (though most are liquid ethane and methane). That doesn’t seem to make much of a difference considering the chemistry of it, but according to astronomer

New insight on water’s strange properties

The paradox of water is that everybody knows it, but no one really understands it. It’s the most fascinating substance we have come across so far, and it still has many secrets for us. For example, the molecular structure of water still eludes scientists, and as a result, water still has many properties which we poorly understand. However, work conducted

Haiti needs water

Haiti is the poorest country in the Western hemisphere, with it’s dazzling 70% unemployment rate and more than 3 quarters of the people living in extreme poverty.  To top it off, water, what you need the most for survival, is polluted. The World Bank pretty much summed it up in a few words: Haiti has the worst water situation in

How much water do you really use

A while back, I got to see this really great water chart from good magazine, and I really think you should take a look at it. Again, it’s their image, so if you want the full size, which is way better, check it out here. Or  click the image

Ultimate recycling: urine for water

This is not for the average man, but when you’re more than 300 km above the Earth, it’s pretty hard to get a glass of water. The estimated cost to transport a pint would be about 15 000$ which is well, astronomical to say the least. So finding a way to recapture every drop of water was vital for scientists.

The price of oil without water

The environmental challenges we have to overcome (fast) cover virtually every field in human activity. Focuses such as finding green fuels, renewable and sustainable sources of energy and other related findings attract more people, more ideas, and visible steps are made towards the right direction. Probably the only concern is how fast and how effective these methods will prove to

The man who farms the sea

Credits A few miles inland from the Sea of Cortez, cracked earth contrasts with the clear, cloudless sky to create a beautiful yet cruel and unforgiving landscape. Here, resources are scarce and people are even fewer. Still, one man fights agains all these adversities; amid mosquitos, cactus, and an almost unbearable heat Carl Hodges manages to create fluorishing crops. He

Moon did hold water

Scientists have believed for years that the moon doesn’t have water, only to find that its interior proved them wrong, challenging our current understanding on how the satellite was formed The current most accepted theory is that it formed in a violent collision between Earth and another planet-sized object.But if this had been the case, there wouldn’t have been any

Energy efficient light bulbs save water

Photo by jago In a study conducted by researchers at Virginia Polytechnic Institute and State University that claimed a different perspective, it was published that it takes between 3,000 gallons and 6,000 gallons of water to power a 60-watt incandescent bulb for about 12 hours per day in a year. As it turns out, size does matter, so scientists are
