>retirement is bad for mind
while retiring ahead of schedule may be easier on the body, a new set of research has found that it may not be so beneficial for the mind.
the study, conducted at binghamton university, finds that an early retirement can accelerate the usual rate of cognitive decline among the elderly.
the research team analyzed china's new rural pension scheme, as well as china's most recent retirement longitudinal survey, in order to investigate the effects of early retirement and pension benefits on individual cognition among adults over the age of 60.
after going over all of the data, the research team noted a clear trend: individuals receiving pension benefits were experiencing much more rapid mental decline than their counterparts still in the workforce.
the most prominent indicator of mental decline among retirees was delayed recall, a trait widely considered to be an accurate predictor of dementia.
surprisingly, females seemed to experience even sharper mental decline after retiring early.

>vr helps to slash pain
patients suffering from chronic pain could find ease by becoming virtually immersed in scenes of icebergs, frozen oceans and sprawling icescapes, a study has shown.
as well has having a distracting effect, researchers from imperial college london think immersing patients in virtual reality (vr) may trigger the body's own inbuilt pain-fighting systems, calming the discomfort.
a team, led by dr sam hughes from the msk lab at imperial, found that ongoing pain was reduced following vr immersion, and that sensitivity to painful stimuli on the skin was also reduced.
however, the same effect was not seen in people who looked at still images of the polar environment, showing immersion is the key factor.
the team, now plans to further investigate the pathways involved in the vr dampening effect, including whether a dosing regimen would work such as 30 minutes, four times a day and if the effects would be cumulative or remain temporary.
>jet tapes over window crack
an airline in india that taped over a crack in one of its plane windows has insisted that safety is its "utmost concern".
passenger hariharan sankaran noticed the taped crack onboard spicejet flight sg8152 from mumbai to delhi. he shared a picture of the cracked window on twitter, asking: "isn't it a major safety concern? "
spicejet later said that the crack was on the "inner flexi pane and was fixed the same day". "the purpose of the inner pane is to protect the window from scratches. the inner pane doesn't carry structural pressurization loads," it added.
airtight plane windows are essential onboard an aircraft to help maintain the correct air pressure inside the cabin.
at more than 10,000ft, passengers would be unable to breathe due to the lack of oxygen in the air without pressurized air.
last year, a 43-year-old woman died when she was partially sucked out of a broken window following an engine explosion onboard a southwest airlines flight.
>pills erase bad memories
scientists are developing a pill that could help you forget bad memories - and they have just tested it on 60 heart-broken people.
dr alain brunet's memory manipulation study at the mcgill university in quebec, canada, hopes to bring about a pioneering technique for the easing of painful memories.
propranolol, a non-expensive blood pressure drug, is believed to stop proteins in the brain from re-storing the memory in the way it did before, meaning some details of the memory are lost.
dr brunet believes propranolol can dull the emotional pain associated with the memory, and could be taken at any point after the event.
