Former US President Barack Obama have nine different creatures named after him !

Former US President Barack Obama

Barack Obama left the white house on 20th of Jan 2017. He finished his presidential tenure and is headed on his new journey to becomeCitizen Barack Obama. He may or may not have roles in politics, but his name will live forever. The scientific community have immortalized him by giving his name to nine different creatures from extinct lizards to trapdoor spiders. Obama is going to keep the record of having most animal species named after him among US presidents followed by Theodore Roosevelt with seven. Now President Donald Trump has an extinct sea urchin and scaly headed moth named after himTetragramma donaldtrumpi and Neopalpa donaldtrumpi respectively. Sirindhorn, the princess of Thailand, has the most species named after her of any political leader, with thirteen. Lady Gaga has a whooping 19 species of fern named after her.

Boat clinic – “a ship of hope in a valley of flood”

Boat clinic in Assam

There are about 2,400 small and medium island villages in Assam on the Brahmaputra inhabited by a population of about 3 million. They are locally called chars or saporisas in Assam. They represent 8 percent of the total population of the state of 30 million.  Every year the big and mighty Brahmaputra river floods.  Lacs of people get displaced and extensive property, crops and livestocks are destroyed. Health problems become acute. Many get affected by water-borne diseases. A major problem for these people is access to medicines and sustained health care.

Sanjoy Hazarika, director, Center for North East Studies and Policy Research (C-NES).

The boat clinic is the brainchild of Sanjoy Hazarika, director, Center for North East Studies and Policy Research (C-NES). It was while working on a documentary film in Assam in 1996, that Hazarika heard of a pregnant woman dying on a sapori, trying to reach a medical facility. By 2004, Hazarika, a former New York Times reporter came up with the idea of a ‘boat clinic’— that would take doctors and basic healthcare to these areas. He presented this idea to world bank and won the innovation prize (called Akha or hope) in the year 2005.

Why people like action movies: Some science to it

Action movie have been always a safe bet for movie producers, though the budget involved in making a perfect one is too high keeping in mind they have to burn several trucks and collapse many buildings. Action films is all about larger than life visions. When we watch action movies, we expect a spectacular display of events. Filmmakers have developed an armory of cinematic devices  like slow-motion, continuity editing, close-up to direct viewers minds to the screen during movie watching.

Though people say they watch movie to relax, the real fact is brain is very alert and active throughout the entire three hours. The truth is our brain processes most of the stimuli from a movie the way it would process it in real life.

“You know there is nothing up there on the screen that can touch you or hurt you or pull you out of your chair but we react as if they can,” Washington University psychology professor Jeff Zacks

Roast potatoes ‘a potential cancer risk’

Acrylamide is found mainly in plant foods, such as potato products

Potatoes  and Acrylamide

Acrylamide is a chemical used primarily as a building block in making polyacrylamide and acrylamide copolymers. They have proven without doubt to be causing cancer in animal models. Scientist believe that the case is not going to be different in humans. The evidence from human studies is not complete.

Researchers in Europe and the United States have found acrylamide in certain foods that were heated to a temperature above 120 degrees Celsius, but not in foods prepared below this temperature . Potato chips and French fries were found to contain higher levels of acrylamide compared with other foods.

Ice Cream and Science

Good quality ice creams contain more fat and less infused air, making for a denser, richer ice cream

 

Everyone loves to eat ice cream. Its smooth texture, sweet taste and rich flavor makes it a perfect dessert.

Did you know that chemistry plays a great deal in making the ice cream perfect ?

Know the science of making ice cream to make the perfect one

Why ice cream floats in an ice cream soda ?

Ice cream has a lot of ice crystals that float, a lot of fat which floats and a lot of air which for sure floats. Those ingredients all together make ice cream a great floater!

If you refreeze melted ice cream, why is it never as good as it was before?

The liquid ice cream fills up the air pockets, when the ice cream melts. But when it refreezes, there are fewer air pockets and as a result ice cream is less airy and fluffy. The other reason is that when the ice cream melts, the original tiny ice crystals melts off. Refreezing the ice cream makes larger ice crystals which makes the ice cream too crunchy.

Why ice cream tastes overly sweet at room temperature ?

Cold tends to numb the taste buds, because of which they become less sensitive. So more sugar needs to be added to produce the desired effect at the low temperatures in which ice cream is usually served. Hence when you taste ice cream at room temperature it will taste overly sweet.

Why we get head ache while eating ice cream?

It is a kind of short-term headache typically linked to the rapid consumption of ice-cream, ice pops, or very cold drinks. It is also known as Brain freeze. Sensation of brain freeze is caused by a dramatic and sudden increase in blood flow through the brain’s anterior cerebral artery. As soon as the artery comes to normal, the brain-freeze pain sensation goes off.

Food we eat can contribute towards Climate Change

carbon ‘Foodprint’

Food’s carbon footprint, or Foodprint, is the greenhouse gas emissions produced by growing, rearing, farming, processing, transporting, storing, cooking and disposing of the food you eat. How the food is grown or raised and how the food is cooked –both contribute to the carbon footprint.

How Carbon emission is mapped to food?

To understand how carbon emissions is linked to food production, we have to look into all those processes that help in bringing  food from the field to our plates:

Science of Making Yummy Curd or Yogurt

Make tasty and yummy Curd with science

Milk gets converted to tasty and yummy Curd. The credit goes to Protein Casein and Bacteria (mostly). Let’s explore the curd making process in depth. At the end of this, I am sure you will find your learning’s helping you in making better curd.

Little Chemistry:

In a glass of milk, complexes of casein proteins in the form of micelles  floats around. These complexes have negative charge, so they repel each other. When we add to it curd inoculum you are introducing loads of Lactobacillus strain of Bacteria which will make milk acidic.  This causes the casein complexes to change shape and also alter their charge. As a result, instead of repelling each other, the casein complexes coagulate, or come together. As they coagulate, they capture fat and lactose along the way and get combined into a larger and larger solid, which we see as curd.

9 Things Science tells about your Dog

Dog science
Research just proved based on study carried out in 3.4 million people, that owning a dog makes you live longer

Dogs are man’s best friend. They have not become our close friend by accident, but science has a lot to tell on why we love them and why they love us back. If you are a person who has dog as pet you would be aware of many of its behavioral patterns like, what they want to convey by wagging their tail or going round and round before sleeping.

But did you know that most of these behaviors are not just instinctive or related to only your dog, but science have explained it through experiments the reason behind their behavior.

  • Pups Poop Along North-South Magnetic Lines

Dogs apparently prefer to poop while aligned with the north-south axis of the Earth’s magnetic field.

This is based on study carried out by y German and Czech researchers, who spent two years watching 70 dogs while they defecated and urinated thousands of times. The dog researchers used 37 different breeds in their study, from beagles and borzois to Transylvanian hounds.

2. Dogs hair grey faster if they are more anxious 

Researchers have found that  dogs that are anxious and impulsive were more likely to have prematurely gray hair than dogs that were not regarded as anxious or impulsive. Also researchers found that Female dogs tended to have higher levels of grayness than male dogs.

3. When dogs eyes meet yours, did you know both are in love (so it’s not only a human feeling) :

Researchers have found that mutual gazing had profound effect on both the dogs and their owners. Of the duos that had spent the greatest amount of time looking into each other’s eyes, both male and female dogs experienced a 130% rise in oxytocin levels, and both male and female owners a 300% increase ( oxytocin, a hormone that plays a role in maternal bonding, trust, and altruism).

4. Your labrador is all time behind food: it is in its genes

A genetic variation in Labrador retrievers says that they are more likely to seek out food. So  Labrador owners should be aware of the fact that their dogs are hard-wired to pester them more about food, and are more likely to beg.

5. Chocolates are toxic for Dogs !

Chocolate contains theobromine and caffeine that are dangerous to dogs. Once they chew chocolate they may begin to drool excessively or even vomit and have diarrhea. These are signs that the chocolate is toxic to the dog. Research has found that dogs are four times more likely to go to the doc for chocolate poisoning during Christmas time of the year. No wonder chocolate cakes and cookies !

6. Tail wagging. It’s not that simple

Dosa, Idli and Science

L. mesenteroides is the microorganism essential for leavening of the batter and, along with S. faecalis is also responsible for acid production

Dosa and Idli – Two common breakfast or snack options. Though it originated in south India, now you can find these two even in US and European restaurants. Chefs have been continuously reinventing these two by adding new flavors and altering the ingredients. At restaurants we get Plain dosa to Chicken tikka masala dosa.

Have you ever thought on how the batter of idli, dosa gets fermented as you are not adding any inoculate or microbe culture as in making curd or baking bread. All credit goes to microbes L. mesenteroides and S. faecalis.
