The flashy colors of some butterflies could exhibit their speed and activeness, much like a cover of sharp yellow color on a sports car. Recent research indicates birds can learn to understand these visible signs, avoiding not just butterflies they have failed to catch in the past but as well as lookalikes species.
The study offers so much vital proof to date for the notion of elusive mimicry, a method in which animals defend themselves against predators by matching to the colors or structures of agile relatives. Initially suggested over 60 years ago, the theory has been a challenge to experiment with.

As National Aeronautics and Space Administration (NASA) rover Perseverance examines the Mars surface, researchers looking for clues of past life on the distant planet are making use of data collected on a mission that is very much closer to home at a lake in Southwest Turkey.
The National Aeronautics and Space Administration (NASA) says the rock and mineral deposits at Salda are the closest match on earth to those near the Jezero Crater where the rover is arrived and which is assumed by scientists to have once been drenched with water.
Information collected from the Salda Lake may be of help to researchers as they hunt for skeletal traces of microbial life secured in sediment believed to have been stored around the delta and the long-vaporized lake it once fed.

Vogue Italia celebrates the beauty of the animal kingdom on its seven covers. Through the lens of an esteemed photographer, the creatures, from the menacing felines of the wild and the busiest colony of bees to the tame and delicate canine, lamb, and ostrich, are presented in their natural habitats the form in artworks or in a beautified studio shoot to raise awareness on a decades-long initiative.
“Animals do not exist for our purpose, nor as a function of what we would like them to be,” says
Vogue Italia editor in chief
Emanuele Farneti. “And it seems almost too obvious that the fashion industry, like any other economic activity, must ask itself where the limits lie in the exploitation of natural resources, and what prospects are offered by technological aspects.”
Why eco-labelling is so difficult during the COVID-19 pandemic In partnership with
We’ve all, at some point, bought an eco-labelled product.
The eco-labels we come to trust are often ones backed by credible audits that involve in-person inspections of production facilities to check that environmental and ethical claims are real.
The COVID-19 pandemic and efforts to contain it have meant that audits have had to change. But changes made to audits that aim to retain credibility such as making them virtual have consequences for fairness. Businesses in lower income countries already struggle to access the benefits of eco-labels. Virtual audits stand to make the situation worse.
