This is Good News Friday, where we find some good economic, energy, and environmental news and share it with PP readers. Please send any positive news to [email protected] with subject header "Good News Friday." We will save and post weekly. Enjoy!


EU to stop changing the clocks in 2019 (tmn)

Critics have also cited long-term health problems, sleep-related issues and the reduced concentration that often accompanies the twice-yearly change. Proponents of daylight savings have long argued that it benefits public safety as well as saving energy.

NASA’s planet-hunting TESS spacecraft captures ‘first light’ image (Thomas R.)

The James Webb Telescope (that is, when it launches) and various ground-based telescopes will then use spectroscopy to measure the light passing through the atmosphere of the new planets TESS finds to learn more about them. NASA expects to figure out their atmospheric compositions, masses and densities using spectroscopic techniques.

How To Get Strong (jdargis)

Everyone knows that exercise is one of the best things you can do for your health. But most people ignore one crucial component of it: resistance training. According to federal researchers, only 6 percent of adults do the recommended minimum amount of at least two muscle-strengthening workouts each week. Neglecting resistance training – any type of workout that builds strength and muscle – is a big mistake. It increases your metabolism, lowers your body fat and protects you from some of the leading causes of early death and disability.

This 94-year-old hands out chocolate bars to strangers. And people love it (Thomas R.)

Jan Hartwig-Heggen, one of Williams’ close friends, told CNN that the “Candy Man,” often clad in a yellow slicker or the gear of his beloved Iowa Hawkeyes, is a popular guy around their town of 800 people. “People love to honk at him when they drive by.”

Scientists uncover why sauna bathing is good for your health (Adam)

Scientists in Finland have shown that sauna bathing is associated with a variety of health benefits. Using an experimental setting this time, the research group now investigated the physiological mechanisms through which the heat exposure of sauna may influence a person’s health. Their latest study with 100 test subjects shows that taking a sauna bath of 30 minutes reduces blood pressure and increases vascular compliance, while also increasing heart rate similarly to medium-intensity exercise.

‘For me, this is paradise’: life in the Spanish city that banned cars (Will H.)

“The historical centre was dead,” he says. “There were a lot of drugs, it was full of cars – it was a marginal zone. It was a city in decline, polluted, and there were a lot of traffic accidents. It was stagnant. Most people who had a chance to leave did so. At first we thought of improving traffic conditions but couldn’t come up with a workable plan. Instead we decided to take back the public space for the residents and to do this we decided to get rid of cars.”

Your Smartphone Can Measure Your Radiation Exposure (Thomas R.)

Gamma rays have far more energy than visible light photons: for example, they might have 20,000 eV compared to between 1.77 and 3.1eV for visible light from red to violet respectively.

And because they have much higher energy to start with, they transfer far more to any electron they hit. This in turn then careers through the material ionising other electrons until its energy is dissipated.

This is what the oldest confirmed animal fossil looks like (Paul D.)

It’s not clear when Dickinsonia lived, but well-dated fossils are 558 million years old, said Jochen Brocks of the Australian National University in Canberra, a study author. Whether they’re the oldest known animal fossils is a tricky question, because some older rock features have also been interpreted by some researchers as fossils of animals, he said.

Found Sounds from the Edge of Earth (tmn)

On the track “Is the Water Supposed to Be This Blue?”, Whetham turned the vibrations of the German Alps into a nearly 23-minute blissfully-droning sound piece. “Open and Closed Circles” merges field recordings taken from 10 locations over a three-year period, from the Chilean city of Valparaíso and Wongol village in South Korea, to Japan’s Mount Tsukuba and the Icelandic village of Garður. While Whetham’s sound sources are found in largely unknown places, he finds equal inspiration in the everyday.

How to Grow More Food While Slowing Climate Change (Paul D.)

“Although we have a long way to go, I’m impressed by how far farmers across the world and especially in less developed countries have come in moving our food-production systems in a healthy direction,” said John Reganold, a soil scientist at Washington State University in the US, and one of the authors.
