A report by the Joint United Nations Programme on HIV/Aids (UNAids) showed deaths had fallen from a peak of 1.9 million in 2005 to 1 million last year.
It said the "scales have tipped", with more than half of people getting d... |

Spreading cancer caught on film
The way in which every single cancer cell spreads around the body has been captured in videos by a team in Japan.
The normal body tissues show up as green, while the cancer comes out as intense red spots.
The team, at the University of Tokyo and the RIKEN Quantitative Biology Center, says the technology will help explain the deadly process.
The research is on mice so far, but it is hoped ... |

Painless flu jab patch for people scared of injections
A 'painless' sticking plaster flu jab that delivers vaccine into the skin has passed important safety tests in the first trial in people.
The patch has a hundred tiny hair-like microneedles on its adhesive side that penetrate the skin's surface.
It is simple enough for people to stick on themselves.
That should help more people get immunised, including those who are scared of injections, ... |

An egg a day appears to help young children grow taller
An egg a day might help undernourished young children grow to a healthy height, according to a six-month study in Ecuador.
Whether soft or hard-boiled, fried or whisked into an omelette, eggs appeared to give infants a boost.
It could be a cheap way to prevent stunting, say researchers in the journal Pediatrics.
The first two years of life are critical for growth and development - any stu... |

Drug shrinks ovarian tumours in early trial
A new targeted treatment for ovarian cancer has shown "very promising" results in women in the advanced stages of the disease.
It shrunk tumours in around half of women who took part in a small trial.
Researchers had only been testing the drug to see if it was safe for humans to take, but found it had an almost instant clinical effect.
It is hoped the drug could help women who have stoppe... |

'Fat but fit is a big fat myth'
The idea that people can be fat but medically fit is a myth, say experts speaking in Portugal.
Their early work, as yet unpublished, involved looking at the GP records of 3.5 million people in the UK.
They say people who were obese but who had no initial signs of heart disease, diabetes or high cholesterol were not protected from ill health in later life, contradicting previous research.

Non-O blood group 'linked to higher heart attack risk'
People with a non-O blood group have a slightly increased risk of heart attack and stroke, research suggests.
Scientists say it could be because higher levels of a blood-clotting protein are present in people with A, B and AB blood.
The findings could help doctors better understand who is at risk of developing heart disease, the researchers said.
But a heart charity said people should foc... |

Cycling to work can cut cancer and heart disease, says study
Want to live longer? Reduce your risk of cancer? And heart disease? Then cycle to work, say scientists.
The biggest study into the issue linked using two wheels with a halving of the risk of cancer and heart disease.
The five-year study of 250,000 UK commuters also showed walking had some benefits over sitting on public transport or taking the car.
The team in Glasgow said cycling took no... |

Ketamine depression treatment 'should be rolled out'
Doctors trialling the use of ketamine to treat depression are calling for the treatment to be rolled out.
Ketamine is licensed to be used as an anaesthetic but has a reputation as an illegal party drug.
Writing in The Lancet Psychiatry, Dr Rupert McShane, who has led a trial in Oxford, since 2011 says ketamine can work on patients with depression "where nothing has helped before".
However... |

Lung probe 'to help cut the unnecessary use of antibiotics'
A lung probe that diagnoses bacterial infections could prevent unnecessary use of antibiotics in intensive care units, researchers believe.
The fibre-optic tube can show within 60 seconds whether a patient needs to be treated with the drugs.
It is hoped the Proteus technology could tackle the emergence of bacteria that are resistant to antibiotics.
The project has been developed by scient... |
