Asta nu e un trucaj:
Fairy wasps are some of the tiniest creatures on Earth, an entire insect roughly the size of a single-celled organism like an amoeba. That means their individual cells must be incredibly tiny...and that requires losing much of their nervous system.
The fairy wasp, otherwise known as the fairyfly, is a parasitic insect that can measure as little as 200 micrometers long, making it roughly the size of unicellular organisms like amoebas or paramecia. Of course, this insect isn't a one-celled organism, which means its thousands of individual cells have to be shrunk down to unbelievably small sizes.

We’ve all experienced it: The frustration of entering a room and forgetting what we were going to do. Or get. Or find.
New research from University of Notre Dame Psychology Professor Gabriel Radvansky suggests that passing through doorways is the cause of these memory lapses.
“Entering or exiting through a doorway serves as an ‘event boundary’ in the mind, which separates episodes of activity and files them away,” Radvansky explains.
“Recalling the decision or activity that was made in a different room is difficult because it has been compartmentalized.”

the panasonic LDAHV4L27CG LED bulb is the first in the world to use clear glass to show the light source.
with its single filament it uses just 4.4 watts. the ultra long life LED bulbs can achieve a lifetime of 40,000 hours
which is approximately 40 years (at usage of 2.7 hours per day).
lighting designers will appreciate them probably also because most of us still love the sharp shadows created
by clear tungsten bulbs. LED delivers 100% of the light instantly. so no need anymore to wait a warm up of the lamp.
you can finally truly use it in a staircase or bathroom or wherever the light needs to be switched on 100% instantly.
with same dimensions as the traditional light source, it can be used as a perfect replacement for incandescent light bulbs.
feel free now to switch on or switch off the bulb anytime as you want. the panasonic LED circuit enables almost
infinite switch on & off cycles (100,000 times) without damaging the lifetime.
