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-…

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 t…
