For years, scientists have speculated about the nature of water on exoplanets, especially on super-Earths and sub-Neptunes — planets larger than Earth but smaller than Neptune. The prevailing view has been that these distant worlds could be covered by vast oceans, potentially making them prime candidates for hosting life. However, a groundbreaking study published in […]
Mars may have oceans' worth of water — but it's more than 10 km under the surface.
Remote sensing reveals the intensity of past and present river flows on other worlds.
It’s made from hydrogel, a naturally absorbent material.
From marble blue to very, very brown.
You'll be shocked to see how much water meat production requires.
Clouds come in all sorts of shapes and sizes. Each type can mean different weather conditions.
Water really is a strange liquid.
This will vary a lot from person to person, but the ‘rule of three’ is generally valid: 3 days without drink and three weeks without food.
This is very good news for the future.
In case you were wondering no, this is not a good thing.
This research proves that Mars used to have quite a lot of surface water.
The findings can help us better predict how water behaves in some extreme environments on alien planets.
Critical drinking water supplies are on the verge of running out in the western USA.
It might seem pointless, but it’s not the water that spoils.
The city's governor believes this is one of the very real effects of climate change.
Such a device may help millions avoid exposure to harmful, heavy metals.
Officials are calling for people to reduce 15 to 20% of their water use.
We take it for granted, but for hundreds of millions of people, water is a scarce treasure.
Empty tables are a chilling prospect.
There are some concerns regarding the use of this tech near marine life, but the concept works.
It could save and improve lives.
No alchemy involved -- just clever science.
All it needs is electricity, air, and a gold-palladium catalyst.
It raises the possibility that other melting glaciers are behaving the same way.
It's their problem today, but it's going to be our problem in the future.
Hard water can ruin your washing machine, but also your hair and skin. On the flipside, it's great for drinking!
Not being tectonically active has its drawbacks.
That's pretty metal!
It's all due to the physics of the scattering of light.
They might be small, but these mussels shoulder tremendous responsibility.
Exposure to chromium can lead to lung cancer and liver damage
This would be very helpful.
They might be comfortable, durable, and in no need of washing -- but there's another side to jeans production.
You'd probably laugh at the idea of someone stealing water -- but that's because you live in a place where water is cheap.
Our solar system is getting more interesting with each passing year
Tea drinkers, you were right: it's not the same if you microwave it.
That's not something you see every day.
Although Pluto orbits the sun at an average distance of 3.7 billion miles (5.9 billion kilometers), some studies claim that the icy dwarf planet may have a liquid ocean under its surface. According to a new study, the accretion of new material during Pluto’s early geological history may have generated enough heat to sustain the […]
New research from ARC Centre of Excellence for Climate Extremes, Australia, says we’ll see longer and more frequent droughts due to climate change. Southwestern Australia, parts of southern Australia, as well as regions in the Amazon, Mediterranean and southern Africa can expect to see more frequent and intense droughts in the future as climate patterns […]
Cleaner air might make for cleaner waters, too.
Researchers found fragments of plastic in sea spray.
Some rising tides sink all boats.
Warmer, wetter tropical soil increases microbial activity -- which belch out CO2.
Contaminants ranged from antibiotics to fire retardants.
"It has been made much worse than it would have been because of climate change," the authors explain.
A team of researchers from the US and China has developed a passive, solar-powered desalinization system that could quench the thirst of remote, arid coastal areas on the cheap. The system employs several layers of solar evaporators and condensers stacked on top of each other in a vertical array, topped off with an insulating layer […]
Jellyfish can sting swimmers and their prey with 'mucus grenades'
Too many rules can spoil the broth.
This was the first time such a behavior was observed in insects and may represent a unique adaptation to bees.
