Most of Britain is experiencing a heatwave, with temperatures reaching up to 32℃. The public health watchdog for England has issued an amber health warning, advising people to take care in the hotter weather. But what does it mean for runners? Is it ever too hot to go for a run?
When – and why – did people first start using money?
Hate vegetables? You might have super-taster genes!
Do you hate vegetables? You’re not alone. About 20% of the population are “super-tasters”. Super-tasters have more taste buds than other people and are super sensitive to the bitter compounds found in some food and drinks, even at low concentrations. If you have inherited super-taster genes then cruciferous vegetables (flower vegetables in the cabbage family) like bok choy, broccoli, Brussels sprouts, cauliflower, radish, swede, turnip, and watercress will taste disgusting.

Choosing healthy food: your surroundings can help or hinder your dining choices
We know too much sugar is bad for us, but do different sugars have different health effects
Our recent article published in the Medical Journal of Australia found that Australian and European soft drinks contained higher concentrations of glucose, and less fructose, than soft drinks in the United States. The total glucose concentration of Australian soft drinks was on average 22% higher than in US formulations.
Maybe the Aliens Aren't Hiding, They're Sleeping, Waiting for the Universe to get Better
When you consider that age of the Universe – 13.8 billion years by our most recent counts – and that which is “observable” to us measures about 27.6 billion light years in diameter, you begin to wonder why we haven’t found signs of extra-terrestrial intelligence (ETI) beyond our Solar System. To paraphrase Enrico Fermi, the 20th century physicists who advanced the famous Fermi Paradox – “where the heck are all the aliens?”
How the red fox adapted to life in our towns and cities
Flexible foxes can be found in almost any sort of terrain. Indeed, one species, the red fox or Vulpes vulpes, is the most widely distributed land carnivore of all, ranging from the Arctic to North Africa. And where its rivals stick to the countryside, these foxes have made themselves at home in modern towns and cities. Why is this?

The science of taste, or why you choose fries over broccoli
Most people say that if there is a healthy choice on a menu they will take it. But observations and research show this is generally not the case. Instead, people tend to make choices based on how food tastes. Typically, the more sugar, salt and fat in the food, the more we will like it. Genetics, experience and environment also influence our perception of food and the consumption choices we make.
Star Should Have Gone Supernova, But it Imploded Into a Black Hole Instead
Collapsing stars are a rare thing to witness. And when astronomers are able to catch a star in the final phase of its evolution, it is a veritable feast for the senses. Ordinarily, this process consists of a star undergoing gravitational collapse after it has exhausted all of its fuel, and shedding its outer layers in a massive explosion (aka. a supernova). However, sometimes, stars can form black holes without the preceding massive explosion.

Health Check: can chopping your vegetables boost their nutrients?
We all know eating vegetables is a good way to improve health. And for many years the focus has been on just eating more vegetables, be it fresh, frozen or tinned.
But what if there was a quicker and easier way to get more benefit from our vegetables? Can the way we prepare vegetables boost their nutrition? Does tearing or chopping your lettuce makes any difference? And if we chop, does it matter what type of knife we use?
How would engineers build the Golden Gate Bridge today?
When the Golden Gate Bridge went up, it was the longest suspended bridge span in the world – cables hold up the roadway between two towers, with no intermediate supports. And the setting had a number of inherent challenges. It cost about US$37 million at the time; building the same structure today would cost about a billion dollars. So how has the design held up over the past 80 years – and would we do things differently if we were starting from scratch today?

Dinosaur Killing Asteroid Hit in Exactly the Wrong Place
The asteroid that struck Earth about 66 million years ago and led to the mass extinction of dinosaurs may have hit one of the worst places possible as far as life on Earth was concerned. When it struck, the resulting cataclysm choked the atmosphere with sulphur, which blocked out the Sun. Without the Sun, the food chain collapsed, and it was bye-bye dinosaurs, and bye-bye most of the other life on Earth, too.
Finding Alien Megastructures Around Nearby Pulsars
For example, in the summer of 2015, a team of astronomers announced that they found what might be an indication of an alien megastructure around Tabby’s Star (KIC 8462852). However, they were quick to point out that any number of possibilities could explain the strange dimming pattern coming from the star, and subsequent studies offered even more plausible explanations – such as the star having consumed a planet at some point in its past.
