मंगल ग्रह पर स्थित घाटियों के जाल से प्राप्त नए प्रमाण इस बात की पुष्टि करते हैं कि लगभग चार अरब वर्ष पहले नोआकियन काल में उष्ण और आर्द्र जलवायु धीरे-धीरे परिवर्तित होकर लगभग तीन अरब वर्ष पहले हेस्पेरियन काल तक ठंडी और हिममय हो गई थी।
In a study, researchers have resolved the taxonomic challenge of butterflies in the Tarucus genus, also called Pierrots.
For years, chemicals in pesticides were thought to be the culprits, leading to the mass death of insects. Now, a new study has found that toxic pollutants in the air are equally responsible for this misery. Much like in humans, polluted air is affecting the survival, behaviour, health and genes of pollinating insects, honey bees in this case.
Plants have many tricks in their hat to attract pollinators—vivid colours, attractive scents, exciting shapes and patterns, heat and also electric potential. But what is fascinating is how these pollinators process these attractive cues from various plants to pick which flower to visit. If you love chocolates, which one would you choose in a big bag of assorted chocolates? Well, most pollinators must have a similar dilemma. Now, a recent study throws some insights into how insects process so many cues from flowers.
