Sky Wtr: Canned water made from air and sunlight to hit US stores in September
Cans of Sky Wtr, produced by solar-powered hydropanels, will go on sale later this year in the US Madeleine Cuff Canned water distilled from the air will be available to buy in the US later this year, in an effort to promote solar-powered “hydropanels” that provide an off-grid method of producing drinking water. The panels, created by Arizona-based firm Source,…

Quantum ‘super behaviour’ could create energy seemingly from nothing
Quantum states can be surprisingly energetic David Wall/Getty In quantum mechanics, the whole can be much greater than the sum of its parts, according to new calculations. They suggest that several low-energy quantum states could be combined into a state containing regions that are dozens of times more energetic than any of the constituent components. The research may ultimately have…

Elephants seem to invent names for each other
Two juvenile elephants greet each other in Samburu National Reserve in Kenya George Wittemyer Elephants may be the only animals besides humans to come up with arbitrary names for each other, according to an analysis of recordings using machine learning. The analysis found that some calls from African savannah elephants (Loxodonta africana) seem to contain name-like components specific to certain…

How materials that rewind light can test physics’ most extreme ideas
For an experiment designed to reverse time, the apparatus was surprisingly simple: little more than a tank of water. With a puff of air to disturb the surface, Emmanuel Fort created a set of ripples moving outwards in concentric circles. Then, as the waves spread, he gave the tank a practised jolt – at which point they suddenly started travelling…

Asthma treated in mice using offshoot of CAR T-cell cancer therapy
An eosinophil immune cell, which can be involved in asthma KATERYNA KON/SCIENCE PHOTO LIBRARY/Alamy It might be possible to effectively cure the most common form of asthma by using genetically engineered cells to kill off the rogue immune cells that trigger asthma attacks, a study in mice suggests. But making this kind of treatment affordable will be a major challenge,…

Tiny nematode worms can grow enormous mouths and become cannibals
The enormous mouth of a tiny nematode worm Sara Wighard and Ralf Sommer / Max Planck Institute for Biology Tubingen Tiny soil worms called nematodes usually feast on bacteria or algae, and have tiny mouths to suit their diet. But give a baby nematode some fungus and its mouth can as much as double in size – giving it the…

AI pop-ups can help you stop doomscrolling on your phone
An AI program can learn from smartphone users’ behaviours in order to send timely pop-up reminders about when to close attention-grabbing apps. The system effectively reduced how often people opened apps such as TikTok Source link

How the infamous Pitcairn Island became a model of ocean conservation
Pitcairn is one of the remotest inhabited islands in the world Michael Runkel/robertharding/Alamy AFTER four nights at sea on a pitching and rolling ship, the announcement over the Tannoy is the sound of sweet relief. “Land ahoy!” I get dressed and lurch out onto the foredeck. If it really is ahoy, I can’t see it. The sun is coming up…

Wildfire smoke may be deadliest effect of climate change in US
Increased exposure to wildfire smoke is one of the most damaging effects of climate change Nasa's Earth Observatory Exposure to rising levels of wildfire smoke could lead to more than 10,000 additional deaths each year in the US by 2050. This could make deaths due to wildfire smoke the costliest consequence of climate change for the country, accounting for nearly…
