During a recent night dive near the Solomon Islands, a team of scientists were stunned to discover a glowing hawksbill sea turtle. It’s the first documented case of biofluorescence in a reptile. »
European eels are critically endangered. To better understand their lives, researchers tracked them during a migration. Suddenly, three trackers returned very strange data. What, oh what, could have happened? »
Around 60% of all human diseases and some 75% of all emerging infectious diseases are zoonotic, meaning they spread from species to species. This remarkable visualization shows how these problematic pathogens proliferate among the animals. »
The Ig Nobel awards ceremony is a marvelous spectacle encrusted with tradition. But if you really want to know how the winners did their work and why, you need to go to the Ig informal lectures, held at MIT the Saturday after the awards. »

The definition of autism is getting increasingly broader. As a result, we are building a new reality of the disorder that doesn’t accurately represent the most affected population.
Behold Bunostegos akokanensis, an ancient “pre-reptile” that lived during the Permian era some 260 million years ago. Researchers studying its fossilized remains have concluded that it stood upright on all fours, making it the earliest known creature to do so. »
Just five months after scientists in China made history by modifying the germline of human embryos, a research team in the U.K. is requesting permission to do the same, but strictly for research into infertility. Given recent calls for a moratorium on such research, the decision is likely to set a precedent for future… »
It’s no secret that drinking coffee shortly before bedtime disrupts sleep, but a new study suggests that caffeine can actually affect our body’s internal clock, pushing back our natural rhythms by nearly an hour. »
