Exercise is recommended for people who are overweight or obese as a way to reduce their risk of developing type 2 diabetes and cardiovascular disease. But people don’t always have time to exercise as much as they would like, so finding ways to increase the health benefits of exercise is important. Our latest research has found a way to do just that, and it’s to do with timing. This means you might be able to get away with doing less exercise if other commitments, such as family and work, always seem to get in the way.

How do solar panels work? – Nathan, age 5, Melbourne, Australia.

The Sun produces a lot of energy called solar energy. Australia gets 20,000 times more energy from the Sun each day than we do from oil, gas and coal. This solar energy will continue for as long as the Sun lives, which is another 5 billion years.

Solar panels are made of solar cells, which is the part that turns the solar energy in sunlight into electricity.

Solar cells make electricity directly from sunlight. It is the most trusted energy technology ever made, which is why it is used on satellites in space and in remote places on Earth where it is hard to fix problems.

In 2014, the world's top polluter, China, told the United States president they unequivocally  would not even discuss emissions caps or targets until 2030 and American speechwriters quickly tried to spin that into a positive. China had never even agreed on a future date before, they rationalized, so that was progress.

Well, not really, but it was as much as almost everyone else was going to do under the Paris Climate Agreement.

In 1605, England’s parliament was sitting on a powder keg, literally. Like now, the country was bitterly divided between two factions, with religion at the heart of the schism after the Reformation pitted Protestants and Catholics against each other in a life or death struggle. History tells us that instead of seeking a political solution such as an election, a group of 13 Catholic conspirators plotted to blow up parliament.

This is running with click bait titles suggesting massively more people are at risk of sea level flooding than before. But it’s just better elevation maps. The sea level rise is the same but more people than they thought are already living below sea level protected by dikes, as for Holland.

It makes no difference at all if the elevation data is already good. Example story to debunk:

This is mainly due to an increase in their estimate of the number of people currently below sea level (many people already live below sea level not just Netherlands). They estimate that

This is the first day that countries can give their one year notification to leave the Paris agreement. It's no surprise that the US has given notification. But he is not speaking for the city of Pittsburgh, who have taken strong action on climate change for over a decade, and many others in the US are in support of the agreement. Withdrawal is largely symbolic, and won't change anything, as there is no longer central federal support for climate action in the US as is.

In February, the American Association for the Advancement of Science (AAAS) issued a bombastic press release to announce its 2019 Award for Scientific Freedom and Responsibility was going to to Sarath Gunatilake and Channa Jayasumana, anti-glyphosate protesters who claim a causal connection between glyphosate and chronic kidney disease.

AAAS has long been a political body, its leadership has come solely from one political party for the last 35 years. and that means it is often going to pick and choose the science it accepts based on its political skew. But a whole lot of Democratic scientists are in biotechnology, they recognize the consensus on glyphosate and GMOs is even greater than it is climate change, and the blowback to this award announcement happened rapidly.
It's November of 2019 which means that we have officially arrived at the opening of the science fiction cult classic "Blade Runner." Let's talk about what it got right.

I was at a local theater showing of "Evil Dead: The Musical" a few weeks ago and at the end was a lot of 1980s music. The crowd that evening was overwhelmingly high school theater geeks and they knew every song, from "Come On Eileen" to "Take On Me." They knew them well enough to mash up dances from other periods while they were singing.

Every two years the Biennale, a contemporary art exhibition, opens in Venice from May to November. This is one of the most important events of its kind, and it attract millions of visitors to a garden that contains a few dozen different pavillions, each hosting artwork from a different country. Over fifty more such independent museums are scattered around the city center and are free entry - these are even more fun to visit than the main exposition at the "Giardini della Biennale", as they allow visitors to visit the spaces themselves, often old houses or palaces that are otherwise unaccessible. 
Rutgers University wants kids to be afraid this year. Not of ghosts and goblins, but Halloween itself. So they have published 7 hyperbolic risks designed to terrify parents.

Allergies! Marijuana brownies! Makeup!

Getting advice from a poison control center at Halloween is as demoralizing as ordering a steak with a microbiologist: they know so much about absolute risk they have forgotten what real risk is.
