The ‘Golden Death’ Bacterium Found in a Rotten Apple
This “spectacular” pathogen dissolves its host from inside out. For several years in the fall, Marie-Anne Félix would walk through an apple orchard near Paris in search of rotten fruit. Félix, an evolutionary biologist at École normale supérieure, studies tiny, translucent worms called nematodes. These worms feed on bacteria, so they tend to congregate, as their prey do, on the flesh of decaying fruit. In 2009, Félix picked up one such apple rich in nematodes. She took samples back to her lab, where she tried to grow worms and bacteria from the apple in petri dishes.

A major chemical company is building roads made of recycled plastic. They've already stopped 220,000 pounds of waste from ending up in landfills.
Plastic gets a bad rap for clogging up landfills, polluting our oceans, and leaking toxic chemicals, but there may be ways to mitigate its damage. Beginning in 2017, one of the world's largest plastic producers, Dow Chemical, began building roads with recycled plastic as a way to reduce waste. Their combined efforts have saved 220,000 pounds of waste from ending up in landfills.

Critically-endangered Madagascan tortoises hatch at Chester Zoo
Two critically-endangered tortoises the size of golf balls have hatched at Chester Zoo. The infants, born to mum Smoothsides, 50, and dad Burt, who is 75, are the first of their kind to be bred at the zoo for seven years. The radiated tortoises are being cared for in a climate-controlled breeding facility. They will eventually grow up to half a metre long and could live to be 100.

Tobacco plants transformed into ‘green bioreactors’ to benefit human health
Researchers at Western University and Lawson Health Research Institute are using tobacco plants as ‘green bioreactors’ to produce an anti-inflammatory protein with powerful therapeutic potential. The plants are being used to produce large quantities of a human protein called Interleukin 37, or IL-37. The protein is naturally produced in the human kidney in very small quantities and has powerful anti-inflammatory and immune-suppressing properties, providing potential for treating a number of inflammatory and autoimmune disorders like type 2 diabetes, stroke, dementia and arthritis.

99.9999 percent chance we're the cause of global warming, study says
There's a 99.9999 percent chance that humans are the cause of global warming, a new study reported Monday. This means we've reached the "gold standard" for certainty, a statistical measure typically used in particle physics. Humanity burns fossil fuels such as oil, coal and gas, which release carbon dioxide (CO2) into the Earth's atmosphere and oceans. CO2 is the greenhouse gas that's most responsible for warming.

Renewable energy policies actually work
For most of the industrial era, a nation's carbon emissions moved in lock step with its economy. Growth meant higher emissions. But over the past decade or so, that has changed. Even as the global economy continued to grow, carbon emissions remained flat or dropped a bit.

Fat rat stuck in manhole rescued by firefighters in Germany
A multi-agency rescue operation has taken place in the town of Bensheim in Germany after a tubby rat became stuck in a manhole cover. The rat, still plump with winterspeck – which translates literally as winter bacon and refers to extra pounds piled on in the colder months – became stuck after it tried to squeeze through a small gap in the sewer cover.

Mankind is like the fabled frog—we're being boiled alive by climate change
People are so quick to normalize extreme weather in the face of climate change we have become like the proverbial frog slowly boiling alive in a pot of water, scientists warned. In the famous fable, a frog that jumps into a pot of boiling water suddenly realizes the danger it is in and jumps straight out. But if the frog jumps in when the water is cold, and is slowly brought to the boil, the frog will not realize the peril it is in.

The Tiny Swiss Company That Thinks It Can Help Stop Climate Change
Just over a century ago in Ludwigshafen, Germany, a scientist named Carl Bosch assembled a team of engineers to exploit a new technique in chemistry. A year earlier, another German chemist, Fritz Haber, hit upon a process to pull nitrogen (N) from the air and combine it with hydrogen (H) to produce tiny amounts of ammonia (NH₃). But Haber’s process was delicate, requiring the maintenance of high temperatures and high pressure.

Eating ‘zombie’ deer meat is safe, researchers say
Eating meat from “zombie” deer appears to be perfectly safe — for now. Researchers examined about 80 people who’ve feasted on the meat of deer that tested positive for chronic wasting disease — a fatal illness that causes zombie-like behavior in the animals and could spread to humans — and found over the course of the six-year study “no significant changes in health conditions,” USA Today reported on Thursday. The tainted deer meat was unwittingly served to 200 to 250 at a fire company in Oneida County, New York, on March 13, 2005.

The Hard Lessons of Dianne Feinstein’s Encounter with the Young Green New Deal Activists
One imagines that Senator Dianne Feinstein would like a do-over of her colloquy with some young people on Friday afternoon. A group of school students, at least one as young as seven, went to the senator’s San Francisco office to ask her to support the Green New Deal climate legislation. In a video posted online by the Sunrise Movement, she tells them that the resolution isn’t a good one, because it can’t be paid for, and the Republicans in the Senate won’t support it. She adds that she is at work on her own resolution, which she thinks could pass.

Why Global Warming Can Mean Harsher Winter Weather
On the surface it certainly can appear that way. But just because some of us are suffering through a particularly cold and snowy winter doesn’t refute the fact that the globe is warming as we continue to pump carbon dioxide and other greenhouse gases into the atmosphere. According to the National Aeronautics and Space Administration (NASA), the 10 warmest years on record have occurred since 1997. And the National Atmospheric and Oceanographic Administration (NOAA) reports that recent decades...

Found: The Biggest Bee in the World
The humid air in the northern Maluku Islands of Indonesia, also known as the Spice Islands, is heavy with nutmeg and clove. These lowland rainforests were the backdrop for the recent rediscovery of a remarkable animal—Wallace’s giant bee, known locally as raja ofu, meaning “king bee,” and with good reason. Wings spread, the largest specimens (who are actually queens) can be the size of an extra large chicken egg, and they sport jaws like pliers.

NASA Happily Reports the Earth is Greener, With More Trees Than 20 Years Ago–and It's Thanks to China, India
The world is literally a greener place than it was 20 years ago, and the data from NASA satellites has revealed a counterintuitive source for much of this new foliage: China and India. This surprising new study shows that the two emerging countries with the world’s biggest populations are leading the improvement in greening on land. The effect stems mainly from ambitious tree planting programs in China and intensive agriculture in both countries. In 2017 alone, India broke its own world record for the most trees planted after volunteers gathered to plant 66 million saplings in just 12 hours.

Tidal floods driven by climate change may hurt small businesses
Sea level rise, driven by climate change, is causing increased flooding during high tides along much of the U.S. coastline. Though such floods are usually minor, a new study suggests that car traffic patterns could help reveal how floods harm an area’s business revenues. Tidal flooding events “are not one in a hundred years or one in a thousand years. They’re once a week,” says Miyuki Hino, an environmental social scientist at Stanford University.

The World Might Actually Run Out of People
You know the story. Despite technologies, regulations, and policies to make humanity less of a strain on the earth, people just won’t stop reproducing. By 2050 there will be 9 billion carbon-burning, plastic-polluting, calorie-consuming people on the planet. By 2100, that number will balloon to 11 billion, pushing society into a Soylent Green scenario. Such dire population predictions aren’t the stuff of sci-fi; those numbers come from one of the most trusted world authorities, the United Nations.
