Turning Brown 
A four-year-old boy was eating an apple in the back seat of the car, when he asked, “Daddy, why is my apple turning brown?” “Because,” his dad explained, “after you ate the skin off, the meat of the apple came into contact with the air, which caused it to oxidize, thus changing the molecular structure and turning it into a different color.” There was a long silence. Then the son asked softly, “Daddy, are you talking to me?”

How fake images change our memory and behaviour

For decades, researchers have been exploring just how unreliable our own memories are. Not only is memory fickle when we access it, but it's also quite easily subverted and rewritten. Combine this susceptibility with modem image-editing software at our fingertips like Photoshop, and it's a recipe for disaster. In a world where we can witness news and world events as they unfold, fake images surround us, and our minds accept these pictures as real, and remember them later. These fake memories don't just distort how we see our past, they affect our current and future behaviour too - from what we eat, to how we protest and vote. The problem is there's virtually nothing we can do to stop it.

Old memories seem to be the easiest to manipulate. In one study, subjects were showed images from their childhood. Along with real images, researchers snuck in manipulated photographs of the subject taking a hotair balloon ride with his or her family. After seeing those images, 50% of subjects recalled some part of that hot-air balloon ride - though the event was entirely made up.

Horse or cow

Prior to taking retirement and selling off his land, a farmer needed to get rid of all the animals he owned, so he decided to call on every house in his village. At houses where the man was the boss, he gave a horse; at houses where the woman was the boss, he gave a dairy cow.

Approaching one cottage, he saw a couple gardening and called out, ‘Who’s the boss around here?’

‘I am,’ said the man.

The farmer said: ‘I have a black horse and a brown horse. Which one would you like?’

The man thought for a minute and said, ‘The black one.’

‘No, no, get the brown one,’ said his wife.

The farmer said, ‘Here’s your cow.’

First Footing

One of the major Hogmanay customs was "first-footing". Shortly after "the bells" — the stroke of midnight when public clocks would chime to signal the start of the new year —, neighbours would visit one another’s houses to wish each other a good new year. This visiting was known "first-footing",and the luckiest first-foot into any house was a tall, dark and handsome man — perhaps as a reward to the woman who traditionally had spent the previous day scrubbing her house (another Hogmanay ritual). Women or red heads, however, were always considered bad luck as first-foots.

First-foots brought symbolic gifts to "handsel" the house: coal for the fire, to ensure that the house would be warm and safe, and shortbread or black bun (a type of fruit cake) to symbolise that the household would never go hungry that year.

First-footing has faded in recent years, particularly with the growth of the major street celebrations in Edinburgh and Glasgow, although not the Scots love of a good party, of which there are plenty on the night!

Newvaccine could fight nicotine addiction

Cigarette smokers who are having trouble quitting because of nicotine's addictive power may some day be able to receive a novel antibody-producing vaccine to help them kick the habit.

The average cigarette contains about 4 000 different chemicals that — when burned and inhaled — cause the serious health problems associated with smoking. But it is the nicotine in cigarettes that, like other addictive substances, stimulates rewards centers in the brain and hooks smokers to the pleasurable but dangerous routine.

Ronald Crystal, who chairs the department of genetic medicine at Weill-Cornell Medical College in New York, where researchers are developing a nicotine vaccine, said the idea is to stimulate the smoker's immune system to produce antibodies or immune proteins to destroy the nicotine molecule before it reaches the brain.

Are Twitter and Facebook Affecting How We Think?

Is constant use of electronic gadgets reshaping our

brains and making our thinking shallower?

By Neil Tweedie

How many times do you click on your email icon in a day? Or look at Facebook, or Twitter? And how many times when reading on the internet do you click on a link navigating away from the text that was the original object of your enquiry? The web, it seems, is like an electronic sweet shop, forever tempting us in different directions. But does this mental promiscuity, this tendency to flit around online, make us, well, thicker?

Nicholas Carr, the American Science writer, has mined this theme for his new book, “The Shallows”, in which he argues that new media are not just changing our habits but our brains. It turns out that the mature human brain is not an immutable seat of personality and intellect but a changeable thing, subject to “neuroplasticity”. When our activities alter, so does the architecture of our brain. Tm not thinking the way I used to think,” writes Carr. “I feel it most stronglywhen l’m reading.”

Getting Every Child to School

Right now 67 million children are missing out on their right to an education. They can’t go to school because they have to work to survive, because they are girls or even because there are no schools where they live.

Where will these children be when they grow up without the chance to learn?

We’re working to make sure every child goes to school. We’re helping build schools, train teachers, advocating girl’s education and reaching children who have to work or are caught up in emergencies with learning.

You can help uphold every child’s right to an education. Make a donation today to not only give children the chance to go to school, but also save their lives and protect their childhoods.

On the Meaning of Being Chinese

Ethnically speaking, I feel I am complicated to classify, but who isn’t, right? To me, being Chinese-Brazilian in America means a history of living in three opposite cultures, and sometimes feeling that I did not belong in neither, a constant struggle that immigrants, and national citizens, face when their appearance is foreign to natives in the country. Jokingly, I say that I am Asian in America, Brazilian in China, and a “gringa” in Brazil. Nevertheless, 1 believe that dealing with these hard to reconcile extremes have somehow helped me to become more comfortable with my identity.

One of the things that made an incredible impression on me in the film was Frida’s comfort in and celebration of her own unique beauty. She didn’t try to fit into conventional ideas or images about womanhood or what makes someone or something beautiful. Instead, she fully inhabited her own unique gifts, not particularly caring what other people thought. She was magnetic and beautiful in her own right. She painted for years, not to be a commercial success or to be discovered, but to express her own inner pain, joy, family, love and culture. She absolutely and resolutely was who she was. The trueness of her own unique vision and her ability to stand firmly in her own truth was what made her successful in the end.
