Mild to moderate asthma can be difficult to diagnose, as its symptoms change over time and are often affected by other respiratory conditions. A new test, however, is able to definitively determine whether or not a patient has asthma – via just a swabbing of the nose...

Getting your daily dose of vegetables can be tricky – there are only so many serves one person can scarf down in a day. But now it may be a bit easier to hide broccoli in other foods, as Australian scientists have developed a nutritious broccoli powder that can be sprinkled through meals or, if you're feeling particularly adventurous, used to make a broccoli latte...

Imagine only replacing the batteries in a device once a decade, or even once a century. Nuclear batteries could one day let us do just that, but their power density is currently too low to be very practical. Now, Russian researchers have developed a new nuclear battery design based on nickel-63, which has a higher specific energy than regular, commercially-available batteries... Continue R
There's a limited supply of donor human corneas, meaning that not everyone who needs an eyesight-saving transplant can get one. As a result, biosynthetic corneas have recently been developed. These could become quicker and easier to produce, as scientists have now successfully 3D-printed the things... Continue Reading For the first time, scientists 3D-print human corneas Category: Medical
There's a clever relatively-new way of determining what types of animals are present in a specific area – check the environment for their cast-off DNA, known as environmental DNA (eDNA). Next month, scientists will be using the technique in an effort to prove or disprove the existence of the Loch Ness monster...

Scientists from ETH Zurich have developed what they claim is the "smallest and cheapest" electronic nose for sniffing out people, designed with earthquake and avalanche rescue in mind. The nose is an array of sensors to detect various substances which, when found together, would provide the crucial "chemical fingerprint" showing the presence of human life...

Learning new things would be so much easier if we could just download them into our brains, like in The Matrix. Now, biologists at the University of California, Los Angeles (UCLA) have pulled off something similar, effectively transferring a memory from a trained snail into the mind of an untrained one. The experiment could eventually lead to new treatments for restoring memory in Alzheime
Whether naturally or through IVF, conception usually requires an egg and a sperm to get things started. But now, researchers from the Netherlands have managed to skip that step and grow model mouse embryos by combining stem cells instead. The technique can help us better understand the early days of life, and may lead to more effective ways to treat infertility or genetic diseases... Conti
A time crystal sounds like a high science-fiction concept, but they're very real – and as new research reveals, you might have some in your home already. Scientists from Yale University have now spotted the signature of a time crystal in a common crystal that crops up in off-the-shelf crystal-growing kits for kids... Continue Reading Scientists spot the telltale tick of a time crystal in a
From the time we choose whether to hit the snooze button or get up, we make countless decisions every day, but just how the brain manages this mundane task is still shrouded in mystery. Now, researchers at Oxford University have observed in detail the mechanism that lets fruit flies make decisions...
