We've all heard about ancient insects getting preserved in amber (fossilized tree resin), with similarly-preserved items including dinosaur feathers, mammalian red blood cells and a bizarre spider. Now, for the first time, scientists have found an amber-encased prehistoric snake... Continue Reading Scientists find prehistoric baby snake preserved in amber Category: Biology Tags:
For years, scientists have seen silicon as a hugely promising material in the world of lithium-ion batteries. The primary reason for this is that using it as the anode could mean batteries with 10 times the capacity of current versions – at least in theory. But in reality, it easily breaks apart as the battery goes through its charging cycles. Scientists at Norway's Institute for Energy Te
To say "Antarctica is cold" will surprise nobody, but just how cold it can get might. Researchers from the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have now identified the coldest places on the planet, where the mercury plummets to almost -100° C (-148° F) under specific conditions... Continue Reading Scientists record coldest temperature ever seen on
The steady march of aging might not have to be so steady, according to a growing body of research. The latest development, from a team at the University at Buffalo, has now isolated a single gene that controls senescence, the process that stops cells from dividing, and found how easily that can spread among neighboring cells. That makes the gene a crucial target for future work into anti-a
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... Continue Reading Scientists set to search Loch Ness for monster DNA Category:
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...
