Sleep ‘boosts brain cell numbers’

Sleep ‘boosts brain cell numbers’

Scientists believe they have discovered a new reason why we need to sleep – it replenishes a type of brain cell. Sleep ramps up the production of cells that go on to make an insulating material known as myelin which protects our brain’s circuitry. The findings, so far in mice, could lead to insights about [&hellip

Buckingham Palace to host Football match

Buckingham Palace to host Football match

Buckingham Palace is to host its first official football match as part of the Football Association’s 150th anniversary celebrations. The Duke of Cambridge, president of the FA, helped arrange the game between two of England’s oldest amateur clubs. Civil Service FC and Polytechnic FC, both based in Chiswick, west London, will play at the palace [&hellip

Insomnia scans show brain struggles

Insomnia scans show brain struggles

Brain scans of people who say they have insomnia have shown differences in brain function compared with people who get a full night’s sleep. Researchers at the University of California, San Diego, said the poor sleepers struggled to focus part of their brain in memory tests. Other experts said that the brain’s wiring may actually [&hellip

Mini Brain Grown In A Bottle By Scientists

Mini Brain Grown In A Bottle By Scientists

Stem cell scientists have grown a miniaturised “brain-in-a-bottle” which they hope will lead to treatments for neurological and mental diseases. The tiny hollow “organoids”, measuring three to four millimetres across, have a structure similar to that of an immature human brain including defined regions. But the scientists insist they are still a long way from [&hellip

‘Molecular basis’ for jet lag found

‘Molecular basis’ for jet lag found

Scientists believe they have figured out why it takes us so long to adapt when we travel to new time zones. Researchers at Oxford University say they have found the “molecular brakes” that prevent light resetting the body clock when we fly – causing jet lag. Experiments, reported in the journal Cell, showed “uncoupling” these [&hellip

A travel pass in form of a ring

A travel pass in form of a ring

Two students in the US have developed a wearable device that could spell the demise of the bus or train pass. The Sesame Ring is a 3D-printed ring that can be loaded with money and then placed on a scanner to allow the traveller to pass through the turnstile. It was created by engineering and [&hellip

Broccoli ‘slows down arthritis’

Broccoli ‘slows down arthritis’

Eating lots of broccoli may slow down and even prevent osteoarthritis, UK researchers believe. The University of East Anglia team is starting human trials following on from successful lab studies. Tests on cells and mice showed that a broccoli compound – which humans can also get from Brussels sprouts and cabbage – blocked a key [&hellip

Half of teenagers sleep deprived

Half of teenagers sleep deprived

More than half of all teenagers may be sleep deprived, according to experts. A combination of natural hormone changes and greater use of screen-based technology means many are not getting enough sleep. Research has suggested teenagers need nine hours’ sleep to function properly. “Sleep is fundamentally important but despite this it’s been largely ignored as [&hellip

Cocaine ‘rapidly changes the brain’

Cocaine ‘rapidly changes the brain’

Taking cocaine can change the structure of the brain within hours in what could be the first steps of drug addiction, according to US researchers. Animal tests, reported in the journal Nature Neuroscience, showed new structures linked to learning and memory began to grow soon after the drug was taken. Mice with the most brain [&hellip

1 in 10 five-year-olds have a mobile phone

1 in 10 five-year-olds have a mobile phone

Nearly one in 10 children has a mobile phone by the time they are five years old, according to a new study. On average, youngsters are bought their first handset at the age of 11, soon after starting secondary school. However, some 9% of parents said they bought their children a phone when they were [&hellip
