Why Blue Dogs Have Been Roaming Mumbai

Residents of Mumbai began noticing a peculiar sight on August 11: roving stray dogs tinted a light shade of blue. No one knew what to make of these canines, which were spotted in the streets seemingly unharmed but otherwise bucking nature.

Concerned observers now have an answer, but it’s not a very reassuring one. According to The Guardian, the 11 Smurf-colored animals were the result of pollution run-off in the nearby Kasadi River. Industrial waste, including dyes, has been identified as coming from a nearby manufacturing plant. Although dogs are known to swim in the river, the blue dye was also found in the air. After complaints, the Maharashtra Pollution Control Board investigated and found the factory, Ducol Organics Pvt Ltd., was not adhering to regulatory guidelines for waste disposal. They shut off water to the facility and issued a notice of closure last Friday.

“There are a set of norms that every industry needs to follow,” MPCB regional officer Anil Mohekar told The Hindustan Times. “After our sub-regional officers confirmed media reports that dogs were indeed turning blue due to air and water pollution, we conducted a detailed survey at the plant … We will ensure that the plant does not function from Monday and the decision sets an example for other polluting industries, which may not be following pollution abatement measures.”

Animal services workers who retrieved five of the dogs were able to wash off the dye. They reported that no other health issues were detected.

5 Times the Jig Was Up Because the Parrot Squawked

Most of our feathered friends can sing, but only a few can talk. And if those talkers witness something naughty, they might just tell on you.

1. SUSPICIOUS SWEET TALKING

A woman in Kuwait, where adultery is illegal, had been suspicious for some time that her husband was carrying on an affair with their housekeeper. There were little signs, like when she returned home from work early and noticed that he seemed nervous. But it was when the family parrot squawked unfamiliar sweet nothings that she decided to take her suspicions to the police. If her husband wasn’t saying those things to her, how was the parrot learning them? However, because it could not be proven that the parrot hadn’t heard the phrases from a steamy TV show, the bird's evidence was deemed inadmissible.

2. THAT'S NOT MY NAME

In another case of infidelity revealed with a squawk, a man was surprised to hear his beloved African Grey parrot Ziggy say, “Hiya Gary!” when his live-in girlfriend’s phone rang, because his name was not Gary. After he heard the parrot say, “I love you, Gary,” and make kissing sounds when the name Gary was said on TV, he confronted his girlfriend, who admitted she was having an affair with Gary. Not only did he lose his girlfriend, but when the parrot continued to chatter on about Gary in her voice, the man was forced to give his pet up too.

3. THE AWFUL LAST LAUGH

Even when other evidence is already damning, a parrot can add an extra sinister twist to a crime investigation. When an elderly woman was found in a filthy South Carolina home, covered in bedsores and near death, her daughter was charged with elder abuse and neglect (her mother died the next day). The police noted that a parrot in the house repeatedly cried for help and then laughed. They believe it was mimicking the interaction between the mother and daughter: The mother pleading for help and the daughter laughing.

4. REPLAYING THE LAST WORDS

After a Michigan man was found shot to death in his home, his parrot kept repeating a dialogue, alternating between a man and woman’s voice, that went: “Get out.” “Where will I go?” “Don’t f***ing shoot!” His wife—who police believe tried to kill herself but did not succeed—was charged with his murder and was convicted in 2017.

5. GIVING THE CRIMINAL AWAY

Tales of parrots giving the criminal away go back to the 19th century, when the leader of a Paris crime syndicate who went by Victor Chevalier escaped with his beloved parrot from the residence he shared with his wife Marie before the cops descended on him. When an officer was called to another residence for a seemingly unrelated search, he heard as he walked in, a parrot cry out “Totor! Riri!” which happened to be the pet names of Victor and Marie. The discovery of the parrot eventually led to the capture of Victor.

Scientists Reveal the Most Comprehensive Map of Butterfly Evolution Ever—and It's Gorgeous

There are 18,000 known butterfly species in the world, so maybe it’s not surprising that scientists haven’t quite worked out how they’re all related. Recently, scientists developed what is currently the most comprehensive roadmap of butterfly evolution ever, one that includes 35 times more genetic data and three times as many classifications as past butterfly evolutionary trees. Oh, and as Fast Company found, it’s beautiful.

The study, published in Current Biology, drew on genetic data from 207 butterfly species that together represent 98 percent of butterfly tribes (the classification just above genus). Led by Florida Museum of Natural History curator Akito Kawahara and Marianne Espeland of the Alexander Koenig Research Museum in Germany, the study used this genetic data and the fossil record to trace the evolution of different butterfly species and figure out when different species split off from their cousins.

Needless to say, millions years of evolution means a lot of information to visualize in one family tree. Each bold label on the very outside of the circle represents a tribe, like Tagiadini, followed by the individual species that made it into the study, like Tagiades flesus (the clouded skipper). Species are clumped together by subgroup—in this case, Pyrginae (spread-winged skippers)—and color-coordinated by family—in this case, Hesperiidae (skippers).

The solid gray circle near the center, labeled K-PG boundary (for Cretaceous–Paleogene boundary) represents the mass extinction event that killed off most of Earth’s plant and animal species, including the dinosaurs.

The study confirms several pieces of information that butterfly experts had hypothesized about in previous studies, while overturning other hypotheses. Butterflies can be divided into seven different families, and though previous research estimated that the first butterflies appeared around 100 million years ago, this study pushes that date back to around 120 million years ago. But there were just a few early ancestors of butterflies prior to the mass extinction event that wiped out the dinosaurs, after which the butterfly family tree explodes into different branches.

Swallowtail butterflies (the subfamily Papilioninae, to the left in blue) were the first butterfly family to branch off, so they’re a “sister” species to all other butterfly species. Skippers (the family Hesperiidae, in purple) likely branched off next, then nocturnal butterflies like the Hedylidae family (in gray). However, some species that scientists previously thought were sister groups do not, in fact, share common ancestry, including swallowtails, birdwings, zebra swallowtails, and swordtails. The timeline shows that some butterfly species seem to have evolved together along with the plants they feed on or, in some cases, ant species with which they now have a mutually beneficial relationship.
