Smoking cause cancer but it also cure diseases.

Across the board, physicians agree: There’s no doubt that smoking is bad for you. But is it possible that there’s just something about a cigarette habit that might lower a person’s risk of developing Parkinson’s disease (PD)? Of course, smoking a pack a day to maybe prevent the onset of PD hardly makes sense — the adverse effects of puffing on nicotine cigarettes certainly outweigh any potential benefits. Still, the data on smoking and PD is too intriguing to ignore: looking collectively across many studies, it’s estimated that current smokers are 60 percent less likely to get PD than those who have never smoked. Which begs the question: Could there be a drug for PD hidden somewhere within the rolling papers? Researchers believe that maybe there is, and the potential therapeutic agent that they’re intrigued by is nicotine.

One finding, published in Annals of Neurology, revealed that consuming certain foods that contain nicotine, such as plants belonging to the Solanaceae family, could help lower Parkinson’s risk.

The study, led by Dr. Susan Searles Nielsen and her colleagues from the University of Washington in Seattle, included 490 patients who were diagnosed with Parkinson’s disease and 644 individuals without Parkinson’s (the control group).

The researchers gave the participants questionnaires asking about their diet and tobacco use.

They found that people who ate higher levels of edible Solanaceae were at a lower

risk of Parkinson’s disease compared to those who didn’t eat as much. Of all the foods that contained nicotine, the best protection seemed to come from eating peppers.

The protective effects of consuming foods containing nicotine were most noticeable in people who never used other tobacco products.

More expensive the wine is the tastier it gets.🍷🍷

Wine tastes better if we think it’s expensive, according to a new study.

Consumers were found to rate cheap wine more highly if they thought it had a higher price tag.Experts found that preconceived beliefs created a placebo effect so strong that it changed the chemistry of the brain.By packaging cheap plonk as a fine vintage, the drinker was able to enjoy the cheaper wine in exactly the same physical way as if it was far more expensive.

Bernd Webber, of the University of Bonn in Germany, co-author of the report, said: “Studies have shown that people enjoy identical products such as wine or chocolate more if they have a higher price tag.

“However, almost no research has examined the neural and psychological processes required for such marketing placebo effects to occur.”

Participants in the study, which is published in the Journal of Marketing, were told they would consume five wines priced at £55, £28, £22, £6 and £3 respectively, whilst their brains were scanned to measure their response to the marketing techniques.

In reality, the volunteers consumed only three different wines with two different price tags.

Another experiment used labels to generate positive or negative expectations of the pleasantness of a milkshake.

Some consumed identical milk shakes but thought they would be either organic or regular; others consumed identical milk shakes but thought they would be either light or regular.

Participants in both demonstrated significant prejudices, both in how they rated the taste as well as in their measurable brain activity.

The brain scan readings related in part to specific areas of the brain that differ from person to person. Such differences are also associated with known differences in personality traits.

The study concluded: “Using a novel application of structural brain imaging in combination with behavioral experiments, we are among the first to shed light on individual difference variables that affect marketing placebo effects.

“Understanding the underlying mechanisms of this placebo effect provides marketers with powerful tools.

“Marketing actions can change the very biological processes underlying a purchasing decision, making the effect very powerful indeed.”

Food made from electricity and air more nutritious than the plant food.

TAKE one serve of carbon dioxide. Apply high voltage. Wait a few weeks … and enjoy a meal of single-cell protein. It may not be a culinary delight, but it could feed our future.

The creation of artificial food out of thin air – with a few added microbes – is the result of a study by research groups in Finland.

And they say the Food from Electricity program is 10-times more energy efficient than the photosynthesis of plants.

Such protein powder is not about to garnish our plates, but it may soon be reducing the strain on our crops by providing an alternative source of fodder for animal feeds.

Researchers based in Finland created food using electricity, water, carbon dioxide, and microbes. The synthetic food was cooked up as part of a larger project, called Food From Electricity. The project is a collaboration between Lappeenranta University of Technology (LUT) and the VTT Technical Research Centre of Finland.

The technology creates a batch of single-cell protein that contains enough nutrition to replace dinner’s protein. Renewable energy powers the entire system.

While the food is safe for human consumption, the group is developing the protein for use as animal feed. The protein can be used as fodder replacement, and land can be released for other purposes, like forestry and farming of other foods.

One of the most impressive aspects of the project is the use of a mini-bioreactor that is portable. This food using electricity can be created on demand anywhere renewable energy (like solar or wind) is available. The process begins by exposing the raw materials to electrolysis in the mini-bioreactor. The reaction eventually produces a powder that contains more than 50% protein and 25% carbohydrates. The rest of the mixture is fats and nucleic acids. And as weird as it sounds, the texture is customizable by changing up the microbes used in the reactor.

Pitkänen says their next priority is to optimize the system. Currently, the coffee cup-sized bioreactor takes two weeks to produce 1 g of protein. He explains, “We are currently focusing on developing the technology: reactor concepts, technology, improving efficiency, and controlling the process.”

This innovative process can create food anywhere it is needed, which has huge implications for world hunger and climate change if the researchers can scale it up.

Juha-Pekka Pitkänen, Principal Scientist at VTT, says, “In practice, all the raw materials are available from the air. In the future, the technology can be transported to, for instance, deserts and other areas facing famine. One possible alternative is a home reactor, a type of domestic appliance that the consumer can use to produce the needed protein.”

Now Google can change the weather unbelievable!

From fetching all the information on our screens at just one click to helping us access global maps and getting accurate weather predictions, Google has made umpteen other things possible for us  — all in our smartphones. Surprisingly, now it has taken one step ahead by claiming to do something unbelievable!

Google has announced his latest project ‘Google Wind’, with this project the company claims to be able to change the direction of winds, keep a tab on rainfall and control the weather in Netherlands through repurposing the country’s old windmills. The Google Cloud Platform team in Netherlands came up with the novel idea of ‘Google Wind’.

Netherlands is known for its tulips and windmills and has a moist climate where it rains 145 days a year. There are not many sunny days in the year. Google has volunteered to step into provide the country with more sunny days! They shared a video on YouTube to provide a sneak peek into their project. The video caption reads, “Using them [windmills] not to capture wind, but to generate them.” The project is so bold that Google is claiming to even control rainfall.

Ninth planet discovered in our Solar System

Before the discovery of Pluto in the 20th century, it had been theorized that a ninth planet, Planet X, existed beyond Neptune due to the gravitational clustering that could only be caused by a massive object. It was then believed that this planet was found in Pluto, but that never fully quantified the gravitational distortion until scientists at the California Institute of Technology presented evidence that a ninth planet truly does exist with an orbital period of 15,000 years.

The astronomers who published their discovery have calculated that there is “only a 0.007 percent chance, or about one in 15,000, that the clustering could be a coincidence.” Presently, Planet Nine remains hypothetical, but astronomers have calculated its orbit to be quite massive. If it does exist, the planet would likely be approximately 2–15 times the mass of Earth and orbit between 200 and 1,600 Astronomical Units (AU) from the Sun. An AU is 150,000,000 kilometers, which means that the planet could orbit as far from the Sun as 240,000,000,000 kilometers.

Immortality dream for every one but acquired by only one type of organism

The good news is that you can be immortal. The bad news is that you have to become a floating blob of jelly to do so. Scientists have discovered a jellyfish which can live forever.

Turritopsis dohrnii is now officially known as the only immortal creature. The secret to eternal life, as it turns out, is not just living a really, really long time. It’s all about maturity, or rather, the lack of it. The immortal jellyfish (as it is better known popularly) propagate and then, faced with the normal career path of dying, they opt instead to revert to a sexually immature stage.

It turns out that once the adult form of the 4.5 mm-wide species Turritopsis dohrnii have reproduced, they don’t die but transform themselves back into their juvenile polyp state. Their tentacles retract, their bodies shrink, and they sink to the ocean floor and start the cycle all over again. Among laboratory samples, all the adult Turritopsis observed regularly undergo this change. And not just once: they can do it over and over again.

Thus, the only known way they can die is if they get consumed by another fish or if a disease strikes the jelly. However, there are still many mysteries surrounding the turritopsis dohrnii. While the process of reverting from its adult-phase to a polyp was observed several times, it hasn’t been observed yet in nature, only in laboratory environments.

Human body transplantation with plant system… is weird to hear but it is something going to happen in future.

Spinach one the best source of vitamines, minerals, protiens, not only spinach but there are hundred of plant which are beneficial to human from our food to the cosmetics we use in our daily life, but think if plants can used for organ trnsplantation it will be a new revolution in our medical history. Doctors have been reasearching for several years to use spinach leaves for heart transplantation.

It is been a failure to produce artificial heart for organ transplantation because we’re not that good at growing blood vessels, and tissues need blood vessels to, well, stay alive. The blood vessels in our own body range from the aorta’s whopping 3 centimeter diameter to capillaries as thin as 5 microns—15 times thinner than a human hair. Our current techniques aren’t refined enough to create fluid channels that tiny, so bioengineers are hard at work finding other ways to make it happen. So if a person having non fuction heart muscels its very difficult to replace the heart with artificial heart.

One thing we can do is start with an actual organ, like a heart, and stripping it of its existing cells so that all you have left is its underlying structure. It already has blood vessels, after all. From there, the hope is that you could use stem cells to create human heart tissue that matches that of a transplant recipient. There’s just one problem: you need a heart first. It would be great if you could do the same thing with something easier to come by—spinach leaves, for example. “I had done decellularization work on human hearts before,” the study’s lead author Joshua Gershlak said in a press release, “and when I looked at the spinach leaf its stem reminded me of an aorta.” said by Joshua Gershlak.

He figured out a way to remove the plant cells by sending a detergent solution straight through the spinach leaf’s stem into its veins. After that, he had a framework made of harmless cellulose. The team bathed that framework in live human cells, these live human cells soon began growing inside of the tiny veins and beating on the surface of the now-skeletonized leaf. Once it was colonized by human heart cells, the researchers sent fluids and blood-cell-sized microbeads through the veins, demonstrating that blood could flow through the system.

Even though their beating spinach leaf looks like a miniature heart, the researchers don’t plan on replacing entire human hearts with stuff from the salad bar. Instead, they hope to use the technique to grow layers of human heart muscle, which could replace the portions damaged by heart attacks. The technique doesn’t just work with spinach—in fact, this very study also tried it with parsley, Artemesia annua (sweet wormwood), and peanut hairy roots. Different plants could be handy for different purposes. The spinach leaf might be better suited for a highly vascularized tissue, like cardiac tissue, whereas the cylindrical hollow structure of the stem of Impatiens capensis (jewelweed) might better suit an arterial graft. Conversely, the vascular columns of wood might be useful in bone engineering due to their relative strength and geometries. We all knew greens were good for us, but we didn’t realize they were this good.

Ever heard about water chameleon……. It’s not a chameleon actully………….

Mimic Octopus-The name for the Mimic Octopus comes from the fact that they often copy the behaviors of other types of animals in the water. They do this in order to trick predators into leaving them alone. they even copy the shape and colour of other animal. they change there colour according to the surroundings. The Mimic Octopus is found in the area of South East Asia.

They are extremely intelligent and researchers believe they choose an animal to mimic based upon the types of predators that are in the area. They have a great memory so they already have seen what is consuming what in their environment. By selecting an animal to mimic that predators around won’t bother the ensure their own survival.

They are one of the few species of Octopus that make tunnels and burrows under the sand at the bottom of the water. They are able to move along this way protected from various predators. At the same time they are able to sneak up on their own prey and take them down without a battle.

Bioconcrete- A revolutionary way of repairing cracks in building……🏚🏚🏚

Concrete is the most common building material in the whole world, and indeed a long-lasting one. But it’s not indestructible, and when it cracks under pressure from, for instance, change in temperature, air or moisture, it’s both dangerous as well as expensive to fix. Cracks developed in concrete allow penetration of salt and water through it that can corrode the steel reinforcements inside it. No one wants a bridge, skyscraper or a dam to suddenly break apart. So, a technique was needed to be developed to cease the cracking and the job was done by two of the researchers at TU Delft, which is a renowned college in Netherlands. They invented a special type of concrete which can heal itself by the use of bacteria which is termed as Bio Concrete. It is also known as self healing concrete or bacterial concrete.

As the pH value of concrete is very high, only the so-called alkaliphilic bacteria are able to survive in this condition. Moreover, the bacteria have to be able to survive the concrete mixer and then they have to wait for years before being able to carry out their restoration work. Bacteria of the bacillus species are perfect for the job. They can survive for decades in a kind of sleep mode, without food or oxygen. In concrete, they will only come to life if water and oxygen are added to it. In other words, if a crack appears in the concrete, they will be able to multiply and produce limestone, thereby closing the cracks. Once the crack is closed up completely, moisture can no longer get into the concrete, so it will not weaken. This type of technique can be used in hydraulic structures like dam.

Nature have blood ironically (Blood Fall In Antartica)

Blood Falls is a waterfall bursting from the Taylor Glacier in McMurdo Dry Valleys, Antarctica, which was spotted in 1911 by Australian geologist Griffith Taylor.

Scientists initially believed it got its blood red hue from algae living in the water.It wasn’t until 2003 when researchers concluded that the liquid was full of iron oxide, and was likely the remains of a 5 million-year-old ancient lake.

The salty, iron-rich water only becomes red as it interacts with the oxygen-rich surface environment at the falls, a complex chemical reaction called oxidation.

But now a study shows that the red water is continually flowing thanks to a rare hydraulic system which may have been been flowing for one million years.

Water releases heat energy as it freezes, and this is enough to melt surrounding cold ice enough to turn it to liquid. This process allows the water to flow from Blood Falls.

This discovery confirms that the glacier has its own water system.

Taking a shot of alcohol burns your throat here is the reason behind it….

when ever some one drink a shot of hard liquor feels the burning sensation on the way down to the throat. Its not due to the liquor but the ethanol present in it. Ethanol in the liquid makes your throat’s VR1 heat receptors more sensitive, prompting them to perceive your own body temperature as hot. Of course, this doesn’t mean you should do shot after shot without fear of consequences. VR1 receptors activate at about 107°F, but ethanol lowers that to just 93 degrees. Body temperature is normally around 98.6°F, so when you feel that burning sensation, it’s because your body itself is now beyond the threshold for those heat receptors.

“The next time you take a shot and your eyes start watering, just remember it’s not the booze that’s hot, it’s you”

Pink lakes around the world

Reason behind the colour of these lakes

The salt content of these lakes  is so high, it’s comparable to the Dead Sea. The color is the due to the combination of a high salinity, the algae species Dunaliella salina and pink bacteria called halobacteria. The algae and bacteria seem to thrive in waters with such high salt content, causing the whole lake to become the vibrant, unexpected hue.

Let’s have Mars potato🥔🥔🥔🥔

Recent studies and experiments found that Potatoes can be grown even in the extreme environment of Mars, according to a new study that has implications for future manned missions to the red planet as well as helping people survive in harsh climates on Earth.

The International Potato Center (CIP) in Peru launched a series of experiments to discover if potatoes can grow under Mars atmospheric conditions and thereby prove they are also able to grow in extreme climates on Earth.

The Phase Two effort of CIP’s proof of concept experiment to grow potatoes in simulated Martian conditions began in February last year when a tuber was planted in a specially constructed CubeSat by researchers from University of Engineering and Technology (UTEC) in Peru.The CubeSat houses a container holding soil and the tuber. Inside this hermetically sealed environment the CubeSat delivers nutrient rich water, controls the temperature for Mars day and night conditions and mimics Mars air pressure, oxygen and carbon dioxide levels.

“It was a pleasant surprise to see that potatoes we’ve bred to tolerate abiotic stress were able to produce tubers in this soil,” said CIP potato breeder Walter Amoros. The experiments have already provided good news about potato’s potential for helping people survive in extreme environments on Earth, he said.

One of the most exotic night view Light Pillars🌃 🌃

A light pillar is an atmospheric optical phenomenon in the form of a vertical band of light which appears to extend above and/or below a light source. The effect is created by the reflection of light from numerous tiny ice crystals suspended in the atmosphere or clouds. The light can come from the Sun (usually when it is near or even below the horizon) in which case the phenomenon is called a sun pillar or solar pillar. It can also come from the Moon or from terrestrial sources such as streetlights.

Since they are caused by the interaction of light with ice crystals, the crystals responsible for light pillars usually consist of flat, hexagonal plates, which tend to orient themselves more or less horizontally as they fall through the air.

Volcanic lightning (dirty thunderstorm)

A dirty thunderstorm (also volcanic lightning, thunder volcano) is a weather phenomenon that is related to the production of lightning in a volcanic plume.

A study  indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms.

Volcanic eruptions are sometimes accompanied by flashes of lightning. However, this lightning doesn’t descend from storm clouds in the sky. It is generated within the ash cloud spewing from the volcano, in a process called charge separation.

As the plume started going downwind, it seemed to have a life of its own and produced some 300 more or less normal [lightning bolts]. The implication is that it has produced more charge than it started with. Otherwise [the plume] couldn’t continue to make lightning.

Enchanting fire rainbow clouds (ice crystal clouds)🌈🌈❄️❄️

During the summer, if you’re very lucky, you may notice a cloud in the sky that looks just like a rainbow. These so-called “fire rainbows” are actually known as circumhorizontal arcs and can occur when the sun has risen higher than 58° in the sky. For those living at mid-latitudes, the best chance to see this phenomenon is in the middle of summer. The rarity of the event is highly dependent upon latitude and weather conditions. The potential for these arcs to form in Los Angeles is 5-10 times higher than in London.

Aside from the position of the sun, the other ingredient to forming circumhorizontal arcs is cirrus clouds. Cirrus clouds are the thin, wispy clouds that occur at higher altitudes. Because the temperature is so low where these clouds exist, they are made of ice crystals. After the sun is higher than 58°, the light refracts through the plate-like crystals, which act like prisms and create the rainbow.

Circumhorizontal arcs aren’t the only optical illusion created by the sun and cirrus clouds; iridescent clouds, infra-lateral arcs, and circumzenithal arcs are just a few other ways the sun can create beautiful rainbow-colored clouds.

Mesmerizing bio luminescent waves (magical blue waves) 😲😲😲💙💙

One of the most spectacular sights on a night dive in the ocean is to witness the blue waves in a dark night, it seems to be tiny blue stars illuminating in the sea shores. These tiny star like structures are bio-luminescent phytoplankton. This bio-luminescent effect produce by these plankton is due to certain chemical reaction. When certain types of chemicals mixed together produce energy which ‘excites’ other particles on vibration and generate light which causes the glow. The group of chemicals involved to make plankton glow are broadly termed luciferins and the light is produced by a series of oxidation reactions set off by a catalyst called luciferase. This bio-luminescent effect is a defense mechanism for these dinoflagellates (phytoplankton) to cautioned there predators.

  3. Brain cells cannibalize themselves as a last ditch source of energy to ward off starvation. So in very real ways dieting can force your brain to eat itself.
  4. Prescription sleeping pills don’t put you to sleep. They put your brain into a state similar to being in a coma, essentially bypassing any restorative value of sleep.
  5. Although pain is processed in your brain, your brain has no pain receptors and feels no pain. This explains how brain surgery can be performed while the patient is awake with no pain or discomfort.
  6. Everyone dreams, even blind people, for at least 1-2 hours and on an average 4-7 dreams each night. Brain waves are more active while you are dreaming than when you are awake.
  7. Your brain does creative work better when you’re tired. Let’s get creative…..

A printable organ is an artificially constructed device designed for organ replacement, produced using 3D printing techniques. The primary purpose of printable organs is in transplantation. Research is currently being conducted on artificial heart, kidney, and liver structures, as well as other major organs. For more complicated organs, such as the heart, smaller constructs such as heart valves have also been the subject of research. Some printed organs have already reached clinical implementation, and primarily include hollow structures such as the bladder, as well as vascular structures such as urine tubes. Modified inkjet printers have been used to produce three-dimensional biological tissue. Printer cartridges are filled with a suspension of living cells and a smart gel, the latter used for providing structure. Alternating patterns of the smart gel and living cells are printed using a standard print nozzle, with cells eventually fusing together to form tissue. When completed, the gel is cooled and washed away, leaving behind only live cells.

Wire less charging through Wi-Charge devices

Our daily life has became so easy through Wi-Fi system what if we can get a charging system just like wireless internet, no need of wires or plug points to charge. The complexity of charging would be solved in 2 seconds, getting anxiety about missing your chargers and getting your phone dead at crucial moments will be solved just when you walked into a room.

Wi-Charge might not quite signal the death of the wired plug phone charger, but it surely aims to disrupt that need a bit. The device itself looks something like a smoke detector on the ceiling. As long as your phone, tablet, laptop, wireless speakers, etc. are in view of the Wi-Charge, you’ll get the juice. It’s technology they call “line-of-sight.” Initially, Wi-Charge will rely on dongles plugged into your device in order to transmit power, but internally installed receivers would remove that hassle.

The product isn’t commercially available yet, but the first phase will roll out in early 2018. You won’t be able to install one of these suckers in your home just yet. Wi-Charge is making its debut in commercial spaces, which, considering the panic and stress of a dying phone while on-the-go, might be more helpful anyway. Wi-Charge products are approved by the US FDA. They adhere to the IEC 60825-1 International Safety Standard.


Power is delivered using safe, focused, beams of invisible infrared light. Transmitters connect to a standard power source and deliver power to nearby receivers.  Receivers use a miniature photo-voltaic cell to convert transmitted light into electrical power. Receivers can be embedded in mobile devices or connected into an existing charging port. Transmitters automatically identify chargeable devices and discover their power requirements. Several devices can charge at the same time. Power priority is based on power requirements, battery level and other parameters.

Onion makes us cry, why?

Ever cut an onion and started tearing up? Most people do. It turns out when you cut an onion, it releases a gas called, ready for this, Propanethiol S-oxide.It stimulates the eyes’ lachrymal glands so they release tears. Scientists used to blame the enzyme allinase for the instability of substances in a cut onion. Recent studies from Japan, however, proved that lachrymatory-factor synthase, (a previously undiscovered enzyme) is the culprit (Imani et al, 2002).

The process goes as follows:

  1. Lachrymatory-factor synthase is released into the air when we cut an onion.
  2. The synthase enzyme converts the amino acids sulfoxides of the onion into sulfenic acid.
  3. The unstable sulfenic acid rearranges itself into syn-ropanethial-S-oxide.
  4. Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes. The lachrymal glands become irritated and produce the tears!

Normally, your body would signal you to close your eyes. This, of course, is not a good idea if you are cutting an onion. The next best thing your eyes can do is to make tears to protect the eyes. Rubbing your eyes is a bad idea since your hands are likely full of the tear making onion juice. So how do you keep from tearing up? There are many theories out there.

Now we can paint the wires……

The scientists have invented a new product that is electric paint, it is more likely a normal acrylic paint but it is conductive in nature.

Bare Conductive’s Electric Paint is just like any other water-based paint… except that it’s electrically conductive! This means that you can actually paint wires onto things like models, clothes, furniture, walls, almost anything you can think of. Standard acrylic or water-based paints can even be used alongside Electric Paint to act as insulation or to create multi-layer circuitry!

Oh yeah, and now? It comes in a pen! Bare’s Electric Paint Pens are a great electronics prototyping tool for makers of all ages. Nontoxic and water-soluble, they can be used without gloves or mask. Once applied the paint dries quickly at room temperature, and can be removed with soap and water.

It helps in Painting wires or sensors directly onto almost any material, safely and quickly cold solder components, repair small devices and PCBs or create switches and circuit designs straight onto any material.

Some features of Bare Conductive’s Electric Paint are –

  • Water-based, non-toxic and dries at room temperature.
  • Electric Paint can be applied to a wide variety of materials, including (but certainly not limited to) paper, cardboard vellum, wood, metal, plaster, some rubbers, plastics and many textiles.
  • Soap and warm water will take Electric Paint off of most surfaces.
  • Can last years if treated properly and kept dry.

Waitomo Caves A Brilliant Blue Nighttime Glow

But in 1887, Maori Chief Tane Tinorau took English surveyor Fred Mace on an adventure to the caves of Waitomo to show him, and subsequently the world, its magnificence. They took a little raft down a stream into the caverns and looked up to see glittering blue stars somehow illuminating the cave. Mace prepared an account of the expedition, made a map, and supplied photographs to the government. Soon, too, Tane Tinorau was operating cave tours for more than just adventurous surveyors

It’s not magic; it’s just worms. Caves are cool enough geologic formations on their own, but the secret sauce that makes the Waitomo caves awe inspiring is what lives within it: the new Zealand fungus gnat arachnocampa luminosa, which is a type of glowworm. The ceiling of the cave is covered in thousands of these bioluminescent little creatures.

Just as the caves wouldn’t be anything remarkable in the daylight, these insects aren’t very interesting in their mosquito-sized adult stage. But as larva, the little gnats turn the underground scene into a walk-in Lite-Brite. The babies have transparent skin through which a greenish blue light can shine, thanks to a chemical reaction that occurs in an organ in their butts. The purpose of the glow is to attract food and mates. And, of course, tourists.

How pearl is formed and why it is formed inside the oyster??

imagesWhen an irritant, such as sand or a parasite, makes its way between the oyster’s shell and its mantle (the organ that creates the shell), the oyster’s body jumps into defense mode. The mantle starts to wall off the foreign object with nacre, the same substance used in the inner shell and what most would call “mother of pearl.” This process creates a pearl that gets bigger as time goes on, and it stays within the oyster until the oyster dies or humans harvest the pearl.

But not all pearls are the near-perfect spheres you see on necklaces; rather, the pearl takes the shape of whatever object it covers. And different breeds of oyster create different colors of pearls. That’s why you’ll find pearls in oval, teardrop, and “baroque” shapes, and colors ranging from bright white to pale pink to deep black.
