Medieval doctors had to acquire a range of skills including an ability to read Latin texts, a working knowledge of the bodily “humours” and an understanding of the rudiments of blood circulation. Their diagnostic techniques were largely limited to examining a patient’s urine: they could match the colour of the urine to that on a chart, such as one now in the Bodleian Library, which offers an alarming spectrum of hues. After diagnosis, one of the most important treatments was bloodletting, for which physicians used detailed astrological charts.

In late November 1999, a TV producer called me about an alarming report that 44,000 to 98,000 Americans were being killed each year by preventable errors in hospitals and another 1 million were being injured.Could that be true? Based on my research, I replied, the estimate seemed low.

When it comes to news literacy, schools often emphasize fact-checking and hoax-spotting. But as I argue in my new book, schools must go deeper with how they teach the subject if they want to help students thrive in a democratic society. As a new poll shows that Americans struggle to know if the information they find online is true, news literacy remains essential in student education.

Ask anyone to name a philosopher and they’ll likely name a man. So, let’s turn the spotlight on three women: Mary Calkins, May Sinclair, and Hilda Oakeley. They each defended “idealism” – the idea that consciousness composes, or somehow pervades, the universe we live in.Big consciousness theories are trending right now. Ecologists such as Suzanne Simard argue trees can “talk”, and philosophers such as Philip Goff argue elementary particles exhibit basic forms of consciousness. These women should be remembered as part of this blooming tradition.

For the first time in the United States, a gene editing tool has been used to treat advanced cancer in three patients and showed promising early results in a pilot phase 1 clinical trial. So far the treatment appears safe, and more results are expected soon.

More than 200 million people around the world suffered from malaria in 2017. Over 400,000 died. The vast majority – around 90% – were in Africa, where many are all too familiar with the devastating impact of the disease. Young children and pregnant women are the most vulnerable.Protective measures can help significantly to reduce the burden. This includes spraying with insecticides and using mosquito nets. But 100% coverage using these methods is impossible. Until the disease is eradicated, availability of effective treatments is critical.

As women started counting steps and walking to work wearing running shoes and fitness trackers, there was one work-related item that had to change: the briefcase. It’s not suited to walking fast and gets in the way of drinking coffee en route to the office. Enter the working women’s backpack. It’s a trend.The Atlantic announced that this is the year professional women started wearing backpacks, even though some of us swear it’s been going on for a while. The sale of women’s backpacks is up by more than 20 per cent in the past year, but the sale of men’s backpacks has flat-lined.

Last month, Indonesia’s previous Minister of Research and Technology boasted that in 2019, Indonesia had overtaken Malaysia and Singapore in the number of published academic articles.

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 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.

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.
