Give your bones a workout, public told

Too many of us are neglecting to do exercises for strong muscles and bones, says Public Health England (PHE).
It's launched a new report giving advice on how people can age better by doing the right workouts.
While the message about doing aerobic exercise for a healthy heart and lungs is getting through, people are less clear about the need to look after their overall strength too, it says.

Espresso replaces insulin in potentially groundbreaking diabetes treatment

Scientists have found a rather humdrum, but still rather miraculous, way for diabetics to keep insulin in check – a good old-fashioned cup of coffee.

A team led by Biotechnologist Martin Fussenegger at the Swiss Federal Institute of Technology believes it has developed an insulin substitute that can be activated by caffeine, according to RT.

“You could completely integrate this into your lifestyle,” Fussenegger said in a statement cited by New Scientist. “You have a tea or coffee in the morning, another after lunch, and another at dinner, depending on how much drug you need to get your glucose back down.”

Snooze mobiles: How vibrations in cars make drivers sleepy

New research has found the natural vibrations of cars make people sleepier, affecting concentration and alertness levels just 15 minutes after drivers get behind the wheel, according to Science Daily

With about 20 per cent of fatal road crashes involving driver fatigue, researchers from RMIT University in Melbourne, Australia, hope their findings can be used by manufacturers to improve car seat designs to help keep drivers awake.

Professor Stephen Robinson said the effects of physical vibration on drivers were not well understood, despite growing evidence that vibration contributes to feelings of sleepiness.

Drug gets body cells to 'eat and destroy' cancer

Scientists have designed a special type of drug that helps the body eat and destroy cancerous cells.

The treatment boosts the action of white blood cells, called macrophages,that the immune system uses to gobble up unwanted invaders, according to BBC.

Tests in mice showed the therapy worked for aggressive breast and skin tumours, Nature Biomedical Engineering journal reports.

The US team behind the study hope to begin human trials within a few years.

The drug that they designed already has a licence, which they say should hasten the approval process.

People who wake up during the night or struggle to get to sleep are at greater risk of a heart attack or stroke

Poor sleepers are at greater risk of an irregular heartbeat which can raise the chances of a heart attack or stroke, a study has found, according to Daily Mail.

Atrial fibrillation – an irregular heartbeat – affects one in 40 people, meaning there are about 1.4million sufferers.

Researchers have now found regular interrupted sleep could lead to the condition by putting stress on the body and causing electrical changes in the heart.

The problem seems to stem from the disruption of ‘deep’ REM sleep. Analysis of four studies covering more than 14million patients showed people who did not sleep through the night increased their chances of an irregular heartbeat by a third.
