The mystery of how the bluespotted ribbontail ray got its blue spots has been solved by a team of scientists, yielding what they described as a “surprising and fun solution to the stingray colour puzzle.” Their investigations revealed that the electric blue comes not from pigment, but extremely small structures that influence the way light […]

Ahh the bird world, full of incredibly beautiful species that fly, swim, and even just walk (looking at you kiwis) across a vast array of Earth’s diverse habitats. While some species enter the record books for their amazing feats of endurance, soaring for days without touching the ground, we take a closer look at the […]

Whether you prefer briefs, a thong, or even a jockstrap, the garments with which you furnish your undercarriage may descend from an ancestral pair of undies that were first worn in a chilly Siberian cave 40,000 years ago.

When searching for signs of extraterrestrial life, we have for the large part focused on carbon-based lifeforms. It makes sense that we would do so, as the only lifeforms we have found (here on Earth) are carbon-based. Advertisement It has been suggested that silicone could also provide a base for life, though nothing matches carbon’s […]

As pretty much every sci-fi movie ever has taught us, the future is going to be full of lasers. They will power our quantum computers; probe microscopic nooks and crannies in scientific experiments; we’ll use them in medicine, for surgeries, or to assess eye health – the possibilities are endless. There’s just one problem: so […]

Brain fog, trouble concentrating, and memory loss have become common complaints for many people who have contracted COVID-19. In fact, between 10 and 30 percent of the general population has experienced at least one of these post-infection conditions.

Precision time-keeping is moving on from atomic clocks and embracing the revolution that is optical atomic clocks. Over the last few years, these instruments have gone further and further in the precision timekeeping they can demonstrate. Their level now is outstanding, well beyond the capabilities of regular atomic clocks. Advertisement Atomic clocks use cesium atoms […]

New research has discovered that the bodacious bodies of hippos go airborne when they trot, building up enough speed to get all four of their trotters off of the ground simultaneously. They might not be giving Superman a run for his money, but the discovery has revealed that these animals are more athletic than we […]

Life ain’t easy being a songbird in the Chernobyl Exclusion Zone (CEZ). New research has looked into the birds inhabiting the irradiated wasteland and found a link between radiation levels and their gut microbiome, suggesting their health is being impacted by their troubled homeland.  Advertisement The CEZ is a highly contaminated area in Ukraine surrounding […]

It feels like every other day a new species is in peril, so at IFLScience we like to celebate the wins – most recently, we’re excited about some good news for one of the world’s weirdest dolphins.

In recent years, we have observed some stars acting seriously strangely. The classic example is KIC 8462852, better known as Boyajian’s star, or just the “alien megastructure” star. In 2016 and 2017, the star dimmed in unusual ways, leading some to suggest it could have a “Dyson sphere” around it, created by some advanced alien […]
