WHO : Limit Headphone Time To 1 Hour A Day

The World Health Organization recently said that over 1.1 Billion people around 18 - 25 ages are at risk of hear loss due to overuse of personal audio devices such as Headphones and Earphones. And also because of High-Volume music at Bars, Clubs, And Concerts. Hearing loss has potentially devastating results for physical and mental health, education and employment.

How to Prevent this ?

WHO recommends that the highest level of noise should be 85dB only up to 8 hours a day. People should wear ear plugs whenever they visit any concert, night club or bars or anywhere there is loud noise.
WHO also recommends teenagers to limit their listening time to less than one hour a day. You can also use smartphone applications, to monitor safe listening levels.

Some Smartphone Apps :-
  For Android :-  deciBel  , Sound Decibel Meter
  For iOS :- TooLoud Pro , dB Volume Meter
  For Windows Phone :- Audio Meter , Decibel Meter

Why the return trip home feels shorter ?

We have all felt this unique and peculiar phenomena.

A new study has revealed that people reflecting on a roundtrip walk estimated that the return trip took less time than the outward trip.

Many have experienced the "return trip effect," where the return trip seems shorter than the outward trip, even when the trips actually
took the same amount of time.

Ryosuke Ozawa from Kyoto University and colleagues compared a group of 20 men watching two of three pre-recorded walking movies, of either
 an outbound trip and a return trip or two outbound trips.
The participants estimated the length of the two movies both while watching and then again after the two trips.
Only the participants from the group watching an outbound trip and a return trip-a roundtrip-estimated that the second trip took less time than the first trip.

Furthermore, the participants felt the return trip effect only when reflecting on length after the trips.

By comparing the round-trip condition and the non-round-trip condition, the authors suggest that the return trip on a roundtrip may actually make us feel that
time is shorter even without actually being physically part of the trip, and that the return trip effect may not affect the timing mechanism itself, but rather
our feeling of time retrospectively.

Further research is needed to better understand the contribution of the awareness of "return," since the labeling such as "roundtrip" or "return" may be another
factor in inducing the cognitive bias of the return trip effect.

But I don't think it is a research or an explanation of "Why the return trip home feels shorter ? " . For me this was an experiment and it's result is nothing.

Magnetotactic Bacteria

Blakemore (1975) first documented magnetotactic bacteria and found that the microorganisms synthesize chains of nano-sized magnetic particles that function as a compass needle. This "nano-compass" allows the microbe to passively orient itself in Earth's geomagnetic field . These magnetic nanoparticles are synthesized by a specific set of proteins that are contained within membrane-bound organelles called magnetosomes. Each bacterium contains 10–20 magnetosomes, each of which contains a magnetic nanoparticle. The magnetosomes are aligned in a chain-like fashion, which impart a magnetic dipole to the bacterial cell and allows the cells to "sense" Earth's geomagnetic field . 
These prokaryotic Microoganisms are found in freshwater and marine habitats. They are all anaerobes and prefer environments that contains little of oxygen .
Magneto taxis is the process by which magnetotactic bacteria orientate themselves within Earth's geomagnetic field and then use their flagellum to swim to oxygen-poor sediments where the oxygen and redox conditions preferred by these organisms are found.
Today, they are used to distribute drugs to the tumours in human body by operating them with a magnetic machine to give them directions. They use as drug distributors because as still tumour drugs are injected in human body they destroy tumours but they also destroy other things of body which is known as side effects of drugs. Still this process is in research, i hope in few years they are used in hospitals all around the world .
