An Argument For Exercising Before Breakfast

An Argument For Exercising Before Breakfast

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 Does Solar Power Work?

How Does Solar Power Work?

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.

November 5th, Guy Fawkes And The Gunpowder Plot: Torture And Persecution In Fact And Fiction

November 5th, Guy Fawkes And The Gunpowder Plot: Torture And Persecution In Fact And Fiction

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.

Spanish Flu  Pandemic Mass Graves 100 Years Ago Led To Our Zombie Fixation Today

Spanish Flu Pandemic Mass Graves 100 Years Ago Led To Our Zombie Fixation Today

Zombies have lurched to the center of Halloween culture, with costumes proliferating as fast as the monsters themselves. This year, you can dress as a zombie prom queen, a zombie doctor – even a zombie rabbit or banana. The rise of the living dead, though, has a surprising link to another recurring October visitor: the influenza virus.

Unlike Movies, In Evolution The Best Screamers Often Survived

Unlike Movies, In Evolution The Best Screamers Often Survived

Of all the sounds humans produce, nothing captures our attention quite like a good scream. They’re a regular feature of horror films, whether it’s Marion Crane’s infamous shower scream in “Psycho” or Chrissie Watkins’ blood-curdling scream at the beginning of “Jaws.”

Brain Organoids: How Soon Before Lab Grown Mini Brains Achieve Consciousness?

Brain Organoids: How Soon Before Lab Grown Mini Brains Achieve Consciousness?

The cutting-edge method of growing clusters of cells that organize themselves into mini versions of human brains in the lab is gathering more and more attention. These “brain organoids”, made from stem cells, offer unparalleled insights into the human brain, which is notoriously difficult to study.But some researchers are worried that a form of consciousness might arise in such mini-brains, which are sometimes transplanted into animals. They could at least be sentient to the extent of experiencing pain and suffering from being trapped. If this is true – and before we consider how likely it is – it is absolutely clear in my mind that we must exert a supreme level of caution when considering this issue.

What Is Sex For? It Depends On Our Vantage Point

What Is Sex For? It Depends On Our Vantage Point

Few topics arouse as much interest and controversy as sex. This is hardly surprising. The biological continuance of the species hinges on it – if human beings stopped having sex, there would soon be no more human beings. Popular culture overflows with sex, from cinema to advertising to, yes, even politics. And for many, sex represents one of the most intimate forms of human connection.Despite its universality, sex and its purpose have been understood very differently by different thinkers. I teach an annual course on sexuality at Indiana University, and this work has provided opportunities to ponder sex from some provocative angles, including the body, the psyche and the spirit.

Oprah Winfrey, Karl Lagerfeld, And More Celebrities With 10,000X More Carbon Emissions Just From Flying Than The Average Person

Oprah Winfrey, Karl Lagerfeld, And More Celebrities With 10,000X More Carbon Emissions Just From Flying Than The Average Person

The jet-setting habits of Bill Gates and Paris Hilton mean that they produce an astonishing 10,000 times more carbon emissions from flying than the average person. This was the conclusion of my research mining their social media accounts (tweets, Instagram and Facebook posts) as well as those of a number of other celebrities for clues as to where they were in the world over the course of 2017 and how they got there. As such, this estimate is conservative – they may well have taken more flights and not volunteered the information to their millions of followers.

Killer Robots, Mass Unemployment - No One Talks About How AI Systems Reinforce Cultural Bias

Killer Robots, Mass Unemployment - No One Talks About How AI Systems Reinforce Cultural Bias

Artificial Intelligence (AI) is already re-configuring the world in conspicuous ways. Data drives our global digital ecosystem, and AI technologies reveal patterns in data. Smartphones, smart homes, and smart cities influence how we live and interact, and AI systems are increasingly involved in recruitment decisions, medical diagnoses, and judicial verdicts. Whether this scenario is utopian or dystopian depends on your perspective.

The Chemicals In Placebos Matter Too

The Chemicals In Placebos Matter Too

Placebo controls are a gold standard against which new treatments are often measured. If a new treatment consistently proves to be better than a placebo and safe, it can be marketed, sold and prescribed. Otherwise, it can’t – or at least shouldn’t. The problem is that, as our latest study reveals, researchers don’t report what placebos contain. Different placebos have different effects, and the choice of what’s in a placebo can lead to mistaken inferences about a new treatment’s benefits or harms.

Is "Groupthink" A Problem For Climate Science?

Is "Groupthink" A Problem For Climate Science?

When the Australian federal environment minister, Sussan Ley, went snorkeling on the Great Barrier Reef in August, she told waiting reporters on the shore that she’d seen “amazing wildlife, fish, turtles, clams … a reef teeming with life”. Such an upbeat assessment seems at odds with the Scientific Consensus Statement, released by the Queensland government in 2017, which said “key Great Barrier Reef ecosystems continue to be in poor condition”.
