Study: Looking young may mean living longer - Yahoo! News

"ONDON – Those baby-faced people now have another reason to be smug: a new Danish study says looking young apparently means a longer life.

Research published online Monday in the British medical journal BMJ suggests that people who look younger than their years also live longer.

In 2001, Danish researchers conducted physical and cognitive tests on more than 1,800 pairs of twins over aged 70, as well as taking photos of their faces. Three groups of people who didn't know the twins' real ages guessed how old they were. The researchers then tracked how long the twins survived over 7 years.

The experts found that people who looked younger than their actual age were far more likely to survive, even after they adjusted for other factors like gender and environment. The bigger the difference in perceived age within any twin pair, the more likely it was that the older-looking twin died first.

They also found a possible biological explanation: people who looked younger also tended to have longer telomeres, a key DNA component that is linked to aging. People with shorter telomeres are thought to age faster. In the Danish study, the more fresh-faced people had longer telomeres."

'Star Trek' gadget to detect cancer - Telegraph

  • urrent tests for cancer and heart disease are subjective, expensive and
    labour intensive.



    They involve taking a blood sample, sending it to a laboratory, using a
    centrifuge to separate the different components, isolating the plasma and
    putting it through an hours-long chemical analysis.



    The whole process takes several days. In comparison, the new device is able to
    read out biomarker concentrations in just 20 minutes.



    The new device could also be used to test for a wide range of diseases at the
    same time, from ovarian cancer to cardiovascular disease, Professor Mark
    Reed co-author said.



    The great advantage of the new machine is that it has a built in filter, to
    remove chemicals that would otherwise distort the readings.

  • hey were again shown the image alone the day after that - and when
    their levels of anxiety were measured their fear had all but gone, the
    journal Nature reports. 


    Being shown the picture without the shock within ten minutes after
    their second exposure to the picture with the shock seemed to rewire
    the brain's response. 


    Dr Daniela Schiller, from New York University, said: 'This suggests
    that during the lifetime of a memory there are windows of opportunity
    where it becomes susceptible to becoming permanently changed.'

    The beauty of the latest approach, say the U.S. researchers, is that it is entirely natural
