Seems that some smelly butterflies don’t get a lot of action, thanks to an anti-aphrodisiac. A new study, led by Kathy Darragh, from the University of California, Davis, has found that male postman butterflies (Heliconius melpomene) make a chemical compound called ocimene in their genitals, which they leave on female butterflies to deter other males. … Continue reading Butterfly turn-off, flower turn-on
Big, BIG night sky map An international research collaboration has just released a map of more than 690 million celestial objects, including stars, galaxies and quasars, as part of the Dark Energy Survey (DES). Over eight years, telescopes in Australia and Chile scanned nearly an eighth of the night sky and looked back in time … Continue reading You may have missed…
