The earthy scent produced when rain falls on dry soil is technically called petrichor. Chemical secretion by plants. The memory-searing, musky smell of petrichor often comes from plants. During the long...

Smelling the ozone. There’s one more prominent source of petrichor that is a little unexpected: ozone.

One of these odors, called "petrichor," lingers when rain falls after a prolonged dry spell. Petrichor — the term was coined in 1964 by two Australian scientists studying the smells of wet weather — is derived from a pair of chemical reactions. Some plants secrete oils during dry periods, and when it rains, these oils are released into the air.

The smell of nature after rain that will be very familiar to anyone who spends much time outdoors, indeed a typical Irish town will have that particular post pluviam odour caused by a mix of geosmin from gardens, parks and hedges and ozone from conrete and tarmac.

The way it smells after the rain is called petrichor.

Birds

Largest bird in the world

Before humans were a major threat, ostriches could be found roaming in Asia, Africa, and the Arabian Peninsula. Today they’re limited to the woodlands and savannas of sub-Saharan Africa. Ostrich eyes aren’t just the biggest of any bird—they’re the biggest of any animal on land. Each eye measures close to 2 inches across. That’s about as large as a billiard ball and even larger than the bird’s own brain. Ostriches have three stomachs. Lacking teeth, ostriches swallow pebbles to grind their food. An adult ostrich carries about 1kg of stones at any one time.

The bee hummingbird

You'll Be Amazed by These Tiny Wonders! Found only in the Americas, hummingbirds are distinguished by their dazzling colours, diminutive size, and speedy flight. You might be familiar with some of the more common species in North America, like the Ruby-throated and Rufous Humming birds. The bee hummingbird is the smallest bird in the world They are the smallest migrating bird. They don’t migrate in flocks like other species, and they typically travel alone for up to 500 miles at a time.
The name, hummingbird, comes from the humming noise their wings make as they beat so fast.
Hummingbirds are the only birds that can fly backwards.
Hummingbirds have no sense of smell. While they can’t sniff out feeders, they do have good colour vision. Some birds like the Ruby-throated Hummingbird prefer orange or red flowers.
The average weight of a hummingbird is less than a nickel.

Irresistible Facts About Baby Animals

Most baby animals are adorable miniatures of their parents, but some go through a bit of a transformation. For instance, baby cheetahs are born without spots, and develop them later, while baby cougars are born with spots, and loose them as they grow.

Phosphenes and Ants

Seeing light without light actually entering the eye.

The spots and colours you see when you rub your eyes are called "Phosphenes". They are a phenomenon characterised by seeing light without light actually entering the eye. The rubbing mechanically stimulates the cells of the retina causing this effect.

The total weight of all the ants on Earth is about the same as the weight of all the humans on earth.

Ants also outnumber us a million to one! They also can lift weight twice their size! Technically, this means that if all the ants were in one place they could lift all seven billion humans...
The total weight of ants is equal to the total weight of humans on earth Here is an interesting fact. All the ants on earth weigh about as much as all the humans. Although individual workers weigh on average between 1 to 5 mg, as per the species.

Future Plants Growth

Artificial Photosynthesis is real and all buildings may have it soon!

Photosynthesis is the process through which plants convert sunlight & CO2 into oxygen & carbohydrates. There’s been a lot of research into how we can perform this process artificially. This would be great both in producing renewable energy and for reducing dangerous CO2 emissions. Artificial photosynthesis also have a big impact in that it won’t compete with the food supply for land. The process could split sea water into Hydrogen and Oxygen.

Natural photosynthesis vs. artificial photosynthesis
In the case of natural photosynthesis, the plant’s leaves absorb carbon dioxide and sunlight while the roots absorb water. Then, light energy stimulates chloroplasts. These are light-sensitive organelles located in plant cells. They trigger numerous chemical reactions that involve chlorophyll, enzymes and other proteins to split water molecules into oxygen, electrons, and hydrogen.

The oxygen is eliminated. Hence, the electrons and hydrogen react with the molecules of carbon dioxide to generate glucose, and the glucose turns into fuel for plants. About 2.5 volts of electrical energy is needed to split a water molecule. In order for this process to occur in an artificial environment, a catalyst combines with light energy. As a catalyst, scientists use light-sensitive substances like cobalt oxide, manganese, and dye-sensitized titanium dioxide.
When it comes to artificial photosynthesis, the structural lead contains thin membranes, microscopic and conductive artificial structures, and nanowires. Scientists use numerous structures and materials to develop artificial photosynthesis. The nanowires in the surface membrane of the leaf structure absorb carbon dioxide, water, and sunlight.
