Streetlights are making caterpillars grow up faster—and that’s a bad thing
To gather caterpillars from hedges, “you basically stick drain piping or any kind of open surface under the hedge, and then you basically whack the hedge with a stick five times. Which causes all of the caterpillars to fall out of the hedge and into your receptacles. So that was quite fun.”
In the grass, it’s a bit easier. “The caterpillars spend the day at the base of these grasses, and climb up the stems at night. So you just go along with a sweep net and just sweep through the vegetation.”
The differences were stark: lighted hedges contained just half the caterpillars of their dark counterparts. Grass had one third fewer.

The First U.S. Funeral Home That Turns Bodies Into Compost Is Now Open

For almost a decade, Katrina Spade has been developing a new way to deal with dead bodies.
In 2011 as a graduate student in architecture, Spade began questioning what would become of her corpse after death. Unsatisfied with the options available, she spent years refining her own solution: “natural organic reduction.”
This December, after years of feasibility studies, fundraising, and legislative efforts, Spade’s company, Recompose, started turning its first customers into compost.

National parks are being overrun by invasive species
Wearing headlamps and muck boots, the band of volunteer conservationists trudges into dark forests in Hawaii Volcanoes National Park and surrounding communities, turning over leaves and shining lights on tree trunks. Their quarry is a tiny frog called the coqui. No bigger than a quarter, the coqui makes an ear-splitting call as loud as a lawn mower: Ko-kee! Ko-kee! It takes special know-how and fortitude to home in on a frog in a blackened forest ringing with frog calls. But the coquistodores are efficient cutthroats. When they find a coqui, they catch it, and drench it in citric acid, killing it.

Should we penalize parents for having ‘extra kids’?
Bill Nye “the Science Guy” did exactly what scientists are supposed to do this week — ask questions — and people are blasting him for it.
The engineer-turned-comedian-turned-TV host has sparked widespread outrage on social media thanks to an idea he proposed Tuesday on his new Netflix series, “Bill Nye Saves the World.”
During a panel discussion, the 61-year-old Cornell grad asked: “Should we have policies that penalize people for having extra kids in the developed world?”
Travis Rieder, a bioethicist at Johns Hopkins University, said he believed it was a good idea.
“I do think that we should at least consider it,” he told Nye.

Scathing Report Accuses the Pentagon of Developing an Agricultural Bioweapon
A new technology in which insects are used to genetically modify crops could be converted into a dangerous, and possibly illegal, bioweapon, alleges a Science Policy Forum report released today. Naturally, the organization leading the research says it’s doing nothing of the sort.
The report is a response to a ongoing research program funded by the U.S. Defense Advanced Research Projects Agency (DARPA). Dubbed “Insect Allies,” the idea is to create more resilient crops to help farmers deal with climate change, drought, frost, floods, salinity, and disease. But instead of modifying seeds in a lab, farmers would send fleets of insects into their crops, where the genetically modified bugs would do their work, “infecting” the plants with a special virus that passes along the new resilience genes.

This town in Greece is draped in thousands of spider webs
It sounds like a something out of a horror movie: A town covered in thousands of webs, each crawling with hordes of spiders.
But for residents of a town in Greece, it's a spooky reality.
In recent days, the webs have draped plants, trees and boats along the lagoon in Aitoliko, a town of canals that's otherwise known as Greece's "Little Venice."
Giannis Giannakopoulos noticed the "veil of webs" earlier this week and captured the spider creations with his camera.

Humans have been messing with the climate for thousands of years
Thousands of years ago, ancient farmers grew oats, corn and wheat, just as they do today. They also cultivated rice and raised livestock. But a millennia ago, they cleared much more land than modern day farmers do, despite having fewer people to feed. That’s because farming was far less efficient. Mechanized harvesters didn’t exist, and growers had yet to develop crops that could be planted in tightly packed rows, yielding more food from less space.
The scientists used a computerized climate model to simulate the climate nearly 777,000 years ago. The climate back then looked more or less what the climate today would look like if not for the warming caused by carbon pollution from ancient farming and modern industrialization, he said. This climate model offered higher resolution than previous models used by the team.

Pests to eat more crops in warmer world
Insects will be at the heart of worldwide crop losses as the climate warms up, predicts a US study.
Scientists estimate the pests will be eating 10-25% more wheat, rice and maize across the globe for each one degree rise in climate temperature.
Warming drives insect energy use and prompts them to eat more. Their populations can also increase.
This is bound to put pressure on the world's leading cereal crops, says study co-author Curtis Deutsch.

Earliest Evidence of Our Human Ancestors Outside of Africa Found
Our ancient human relatives got around more than scientists previously thought. Researchers in China excavated stone tools that were likely made by our human ancestors some 2.12 million years ago — the earliest evidence ever discovered of the human lineage outside of Africa.
"It suggests a way earlier migration out of Africa than we ever would have imagined," said Michael Petraglia, a paleoanthropologist at the Max Planck Institute for the Science of Human History, who was not involved with the study. "It's very exciting."

WE HAVE NO IDEA HOW BAD THE US TICK PROBLEM IS
WHEN RICK OSTFELD gets bitten by a tick, he knows right away. After decades studying tick-borne diseases as an ecologist at the Cary Institute of Ecosystem Studies in Millbrook, New York, Ostfeld has been bitten more than 100 times, and his body now reacts to tick saliva with an intense burning sensation. He’s an exception. Most people don’t even notice that they’ve been bitten until after the pest has had time to suck up a blood meal and transfer any infections it has circulating in its spit.
Around the world, diseases spread by ticks are on the rise. Reported cases of Lyme, the most common US tick-borne illness, have quadrupled since the 1990s. Other life-threatening infections like anaplasmosis, babesiosis, and Rocky Mountain spotted fever are increasing in incidence even more quickly than Lyme. Meat allergies caused by tick bites have skyrocketed from a few dozen a decade ago to more than 5,000 in the US alone, according to experts. And new tick-borne pathogens are emerging at a troubling clip; since 2004, seven new viruses and bugs transmitted through tick bite have shown up in humans in the US.

Inside the vigilante group of New Yorkers who hunt rats at night
Rats aren't only a part of New York City’s underground — they're an inseparable part of its pop culture. There’s Master Splinter from the Ninja Turtles, Pizza Rat, and even Cannibal Rat. But for every celebrity rat, there’s another 250,000 to 2 million anonymous rodents living in the city — and the city health department is fighting to bring down.
Last year, three people in a Bronx city block made the news for contracting leptospirosis through rat urine. Only two survived.

The Y chromosome is disappearing – so what will happen to men?
The Y chromosome may be a symbol of masculinity, but it is becoming increasingly clear that it is anything but strong and enduring. Although it carries the “master switch” gene, SRY, that determines whether an embryo will develop as male (XY) or female (XX), it contains very few other genes and is the only chromosome not necessary for life. Women, after all, manage just fine without one.
What’s more, the Y chromosome has degenerated rapidly, leaving females with two perfectly normal X chromosomes, but males with an X and a shrivelled Y. If the same rate of degeneration continues, the Y chromosome has just 4.6m years left before it disappears completely. This may sound like a long time, but it isn’t when you consider that life has existed on Earth for 3.5 billion years.

Stay away from romaine lettuce, Consumer Reports advises
People should stay away from romaine lettuce until U.S. and Canadian health officials get to the bottom of an outbreak of E. coli infections, Consumer Reports says.
The consumer advocacy group called on the Food and Drug Administration and Centers for Disease Control and Prevention to do more to warn people about the outbreak, which at last count had made 58 people sick in the U.S. and Canada. One person has died.
The CDC last reported on the outbreak on December 28. It said 17 people were sick in 13 states, dating back to November. The Public Health Agency of Canada has reported on 41 illnesses.
“The Public Health Agency of Canada has identified romaine lettuce as the source of the outbreak in Canada,” the CDC said in its Dec. 28 statement.

It Turns Out Your Love of Glitter Is Actually Bad for the Environment
From glitter bombs, beards, makeup and sparkly protest signs, glitter is a mainstay of modern LGBTQ culture. But U.K. scientists are urging the government to ban it because it’s apparently very bad for the environment.
If you’ve ever spilled glitter or used any on your body, than you understand that it never really completely goes away. (That’s part of the reason that glitter is sometimes called “raver scabies.”) It’s non-biodegradable and even when it’s thrown away or washed down the drain, it still ends up in our soil and water supply where it creates even more problems.
The issue, according to Josh Gabbatiss of The Independent, is that most glitter contains a plastic called polyethylene terephthalate (or PET). The PET contained in glitter is microplastic, a word that refers to any small bits of plastic that are smaller than a fifth of an inch.
