Are Flowers Smell So Sweet?
Ozone shields our planet from the sun’s harmful ultraviolet rays, but it may be also be keeping bees away from their favorite flowers, according to a new study. Ozone doesn’t just live high in Earth’s atmosphere; near the ground, it contributes to smog, and ground-level ozone has gradually increased in most places because of industrial pollution from vehicles and fossil-fuel burning. Ozone is known to react with and break down molecules called volatile organic compounds. That’s a concern because flowers emit certain kinds of these compounds that, like a natural perfume, entice bees and other pollinators to visit the flowers. In the laboratory, the scientists exposed groups of them to ozone levels ranging from 0 parts per billion (ppb) of ozone to 120 ppb, which is found in some urban areas. A machine called a mass spectrometer measured levels of scent molecules as far as 4.5 meters away from the flowers. At 4.5 m away, levels of most of the scent’s component molecules ranged from 17% to 31% lower at 120 ppb than at 0 ppb ozone... Little to no decrease occurred at 0 m away, showing that ozone’s effect increases with distance. Additional lab tests showed that unaltered scent is attractive to a common type of bumblebee (Bombus terrestris); bees preferred spending time in scent-laced air over scent-free air, the researchers say. Because some molecules’ levels decreased more than others in the lab tests, the scent’s strength isn’t all that’s at stake: The scent itself may change a bit, too. The findings suggest pollinators could struggle more over time to locate flowers, as ozone pollution in most parts of the world will keep rising as a result of industrialization and climate change.

The Lightest Metal Ever
Aerospace giant Boeing has released a video showcasing the lightest metal structure ever, which is also one of the lightest materials known to science, called Microlattice. The entire structure is 99.99% air and is comparable to the hollow honeycomb architecture of bone. The structure is composed of a network of super thin, hollow struts. The struts are around 100 micrometers in diameter and have walls just 100 nanometers thick. It's this design that makes Microlattice 10 times lighter than Styrofoam. However, despite it being insanely light, it is also extremely strong.If planes made from this material we can fly more faster because this material is the lightest...And this mean burn less fuel...

Why gaming mouse is better ?
Optical mice are better than laser mice.
The laser light has a different wavelength. It is more looking into the structure of the material than the normal LED light, which is more surface illumination. It makes [the laser] more sensitive to the roughness of the surface....The LED is more staying on the top of the surface, so it’s very reproducible. On the top of the surface you have peaks, and it’s only counting the peaks.If you look at the cloth pads that are made out of a structure of fibers, the laser is so accurate it ... is showing you the nature of the structure. You don’t care about that. You just want to measure a distance ... The laser will really go down into the surface and then, especially at low speed, will behave very differently. This is the reason you have a big difference between low and high speed.Laser-illuminated sensors work extremely well on hard pads, but on soft pads with more surface depth, they’re picking up too much useless information, which leads to discrepancies in how they track at different speeds...

You should read book everyday...
When was the last time you read a book?Are you always reading books or never? If you don’t make a habit of reading regularly , you might be an ignorant person... Reading has a significant number of benefits;
1. Mental Stimulation
Studies have shown that staying mentally stimulated can slow the progress of (or possibly even prevent) Alzheimer’s and Dementia, since keeping your brain active and engaged prevents it from losing power.
2. Stress Reduction
No matter how much stress you have at work, in your personal relationships, or countless other issues faced in daily life, it all just slips away when you lose yourself in a great story.
3. Knowledge
The more knowledge you have, the better-equipped you are to tackle any challenge you’ll ever face.
4. Vocabulary Expansion
Reading books is also vital for learning new languages, as non-native speakers gain exposure to words used in context, which will ameliorate their own speaking and writing fluency.
5. Memory Improvement
I guess you already know that...
6. Improved Focus and Concentration
When you read a book, all of your attention is focused on the story—the rest of the world just falls away, and you can immerse yourself in every fine detail you’re absorbing.
7. Stronger Analytical Thinking Skills
If you read very much you can be more clever.
8. Tranquility
Reading spiritual texts can lower blood pressure and bring about an immense sense of calm, while reading self-help books has been shown to help people suffering from certain mood disorders and mild mental illnesses.

Some Weird French Foods
Oeuf à la coque (aka soft-boiled egg yolk) – This is a French staples for kids. Boil an egg for three minutes and place it in an egg cup . Cut off the top of the egg with a knife and dip strips of buttered bread (known as mouillettes) to eat the runny yolk and semi-solidified egg white.
Croque-monsieur (aka grilled cheese sandwich) – People think French cuisine is fancy. It’s actually pretty basic, just the names of dishes are fancy. For instance, we don’t call this French comfort food “sandwich au fromage et jambon grillé” but croque-monsieur—it sounds fancier.
Boudin noir (aka blood sausage) –This is probably while foreigners stay away from this traditional French sausage made with pork, fried onions, fat, and blood.
Steak tartare (aka raw meat) – Steak tartare is a dish made from finely chopped or minced raw beef or horsemeat, often served with onions, capers and seasonings.
Horse meat or rabbit – I never eat this...Why are you cut pretty rabbits man ? :)

Earth Microbe on Meteorites...
The microbe above is happier living on meteorites than on Earth.The microscopic organism—an archaea known as Metallosphaera sedula (seen as a cluster of tiny dots sitting in the middle of the meteoritic dust particle pictured above)—was originally found in 1989 living in Italy's hot acidic sulfur springs around Vesuvius. These so-called chemolithotrophs normally feed on iron and sulfur minerals in rocks and leave behind a residue of heavy metals. This makes them useful in mining operations as an environmentally friendly alternative to leaching the metals with toxic chemicals.To test these microbes’ "astrofermination" capability, the researchers gave them an energy drink made of powdered meteorite and recorded how much nickel they released in the jars. Future work will include testing the survivability of the microbes in a vacuum and with synthetic martian minerals...
