It wasn’t long ago that the idea of the meat on our plates coming from vast stainless steel bioreactors, rather than farmed animals, seemed like science fiction. The notion has gone through numerous rebrands since its early positing as ‘vat meat’, which triggered unappealing visions of high-tech Spam. ‘Lab meat’ came next, as scientists perfected the recipe in small beakers in laboratories. Then came the more appetising-sounding ‘cultured meat’, as investment from high-profile individuals rocketed and producers positioned these products as having been brewed, just like beer. Now, ‘cultured meat’ has evolved to ‘cultivated meat’, which is the preferred term used by CEOs in the industry.
Whatever you choose to call it, with the future of global food security in question, and farmed meat a key culprit in climate breakdown, slaughter-free meat is starting to look increasingly like the future of food.
HOW IS THE MEAT MADE?
Rather than being part of a living, breathing, eating and drinking animal, cultivated meat is grown in anything from a test tube to a stainless steel bioreactor. The process is borrowed from research into regenerative medicine, and in fact Prof Mark Post of Maastricht University, who cultured the world’s first burger in 2013, was previously working on repairing human heart tissue. Cells are acquired from an animal by harmless biopsy, then placed in a warm, sterile vessel with a solution called a growth medium, containing nutrients including salts, proteins and carbohydrates. Every 24 hours or so, the cells will have doubled.
HOW DIFFERENT IS CULTIVATED MEAT FROM THE REAL THING?

COULD MARINE CLOUD BRIGHTENING HELP US FIGHT CLIMATE CHANGE?
The theory behind marine cloud brightening is that brighter or whiter clouds reflect more sunlight back into space.
IS IT SAFE TO RUN EVERY DAY, OR SHOULD I DITCH MY RUN STREAK TO SAVE MY KNEES?
A running streak, where you run every day without taking rest days, can be highly motivating and beneficial for overall fitness. Running is great cardiovascular exercise and isn't to be discouraged (and finding a routine with some consistency is great). Getting a bit of exercise as often as possible is also hugely beneficial for your mental health.
WHAT MAKES THE MEDITERRANEAN DIET SO GOOD FOR US?
The Mediterranean diet may help you live longer, especially if you also adopt the lifestyle of people living near the Med during the 1950s.
WHAT IS MEXICO'S BLUE HOLE?
The world's deepest blue hole (marine sinkhole) lies off the coast of Mexico's Yucatán Peninsula. It's at least 420m (1,378ft) deep, but explorers still haven't found its bottom.
HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?
Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys. It plays a critical role in various bodily functions, including regulating metabolism, reducing inflammation and helping the body respond to stress. While essential for our health, chronic elevation of cortisol levels can lead to several issues.
THE LUNGFISH
In 1836, European scientists discovered a peculiar animal from the River Amazon that they struggled to identify. Its eel-like body was a few feet long and its air-filled lungs persuaded anatomists it must be a reptile.
ARE WE THE ONLY SPECIES TO HAVE BEEN THROUGH A STONE AGE?
The Stone Age might conjure up images of early humans, sitting around a campfire or hunting prehistoric beasts, but evidence shows that we're not the only species that has learned how to work with stone tools. Wild chimpanzees (Pan troglodytes) use stone tools to crack open nuts.
Should we scrap daylight saving time?
Most of us look forward to the extra hour we get in bed every October, but researchers argue that changing the clocks twice a year harms our health
THE INTERNET OF ANIMALS
SCIENTISTS ARE USING ELECTRONIC TAGS AND SATELLITES TO TRACK WILD ANIMALS AND CREATE A DATA NETWORK THAT COULD HELP US ADDRESS THE BIODIVERSITY CRISIS
MUSIC FOR A DISTRACTED GENERATION
The number of things competing for our attention is often overwhelming. Can dreamy soundscapes created with neuroscience help our bewildered brains to concentrate?
