Humans Change the World Modern humans evolve in Africa. Image courtesy of Karen Carr Studio.For millions of years all humans, early and modern alike, had to find their own food. They spent a large part of each day gathering plants and hunting or scavenging animals. Then, within just the past 12,000 years, our species, Homo sapiens, made the transition to producing food and changing our surroundings. We have been so successful that we have inadvertently created a turning point in the history of life on Earth. Scientists fix photosynthesis ‘glitch’ in plants and boost crop growth by 40% Scientists have genetically engineered plants so they grow up to 40 per cent larger by tweaking the process they use to turn sunlight into food. Photosynthesis allows plants to harvest the sun’s energy and produces vital oxygen as a by-product, fuelling the rich array of life on Earth. However, this mechanism is hampered by an energy intensive process called photorespiration, which plants have evolved to work around an inefficiency present in regular photosynthesis.
Internet History Sourcebooks Internet Ancient History Sourcebook The Internet Ancient History Sourcebook has expanded greatly since its creation, and now contains hundred of local files as well as links to source texts throughout the net.

Lynn Barber on her liaison as a 16-year-old with an older man I met Simon Goldman in 1960 when I was 16 and he was - he said - 27, but was probably in his late 30s. I was waiting for a bus home to Twickenham after a rehearsal at Richmond Little Theatre, when a sleek maroon car drew up and a man with a big cigar in his mouth leant over to the passenger window and said, "Want a lift?" Of course my parents had told me, my teachers had told me, everyone had told me, never to accept lifts from strange men, but at that stage he didn't seem strange, and I hopped in.
5 Nazi Plans That Prove They Were Dumber Than You Think Other websites like to tiptoe around the issue, but we've never hesitated to come out and just say it: The Nazis were bad. And the thing is, the Nazis weren't strictly about tearing Europe down brick by brick and the Holocaust. They actually had tons of other horrible and, quite frankly, stupid ideas. Not all of them were brought to fruition, fortunately, but at one time or another, Hitler was all about ... The Law of Two-Thirds When we go to college we’re told we can have good grades, a good social life or sleep – pick two. Business is no different. Almost everything we buy can be boiled down to quality, speed or price – pick two. A Rolls Royce, for example, is made from the finest materials and costs a lot of money. But they take a long time to make. A Toyota Camry, in contrast, is fast and cheap and though the quality is good, it’s not the best.
Who were the Mongols? Around 500 BCE, a tribe of nomadic people called the Mongols lived in Asia. The Mongols were traders and herdsmen. They herded sheep and traded horses with the ancient Chinese and Persians. In the summer, they moved with their herds across the vast steppes of Asia, seeking fresh pasture land. They used dogs to help them herd the cattle. Are These 3-D Printed Shoes Artistic Or Misogynistic? In collaboration with the shoe brand Melissa, New York-based designer Sebastian Errazuriz is getting a lot of attention for “12 Shoes for 12 Lovers:” a series of 12, 3-D printed shoe sculptures inspired by his former romantic relationships. The shoes themselves are beautiful and imaginative--one resembles a frozen splash of spilled milk, another has a green plastic army man affixed to the toe. But the whole conceit is casually misogynistic. Each shoe has been given a name based on its "muse," one of the artist's ex-girlfriends, and most of these play into reductive stereotypes of women: “The Virgin,” “Gold Digger,” “Hot Bitch,” “Cry Baby,” “Ice Queen,” "Honey."
5 Whores Who Changed The Course of History For most of us, performing sexual favors in some dark alley for grocery money is about as low as life can get. But history is full of stories of prostitutes who parlayed their skills into positions of prestige and power. And some of them changed the world. Where: Gene editing – and what it really means to rewrite the code of life So what is gene editing?Scientists liken it to the find and replace feature used to correct misspellings in documents written on a computer. Instead of fixing words, gene editing rewrites DNA, the biological code that makes up the instruction manuals of living organisms. With gene editing, researchers can disable target genes, correct harmful mutations, and change the activity of specific genes in plants and animals, including humans. What’s the point?Much of the excitement around gene editing is fuelled by its potential to treat or prevent human diseases.
