Equations Are Art inside a Mathematician’s Brain. When mathematicians describe equations as beautiful, they are not lying.
Brain scans show that their minds respond to beautiful equations in the same way other people respond to great paintings or masterful music. The finding could bring neuroscientists closer to understanding the neural basis of beauty, a concept that is surprisingly hard to define. In the study, researchers led by Semir Zeki of University College London asked 16 mathematicians to rate 60 equations on a scale ranging from "ugly" to "beautiful. " Two weeks later, the mathematicians viewed the same equations and rated them again while lying inside a functional magnetic resonance imaging (fMRI) scanner.
The scientists found that the more beautiful an equation was to the mathematician, the more activity his or her brain showed in an area called the A1 field of the medial orbitofrontal cortex.

Richard Rogers designs $50K flatpack homes for the homeless. In 1971 the firm of Piano + Rogers won the competition to build what became Paris's Pompidou Centre, one of the most important buildings of the 20th century, an icon of high-tech and prefabrication.
They split up in 1977, yet seem to have continued on parallel paths. Last year Renzo Piano showed his lovely little high tech mini-house; now Richard Rogers shows that he can do mini-houses too, with his design for a 300 square foot low-cost prefabricated house, the Y-Cube, designed for the British YMCA. © Rogers Stirk Harbour + Partners. The Science of Pomato Plants and Fruit Salad Trees. A Photoshopped image of an ideal, but improbable, fruit salad tree (Credit: Adapted from various Wikimedia images by Guety, Fir0002/Flagstaffotos, Tobias and MikeyMoose) In an episode of Matt Groening’s animated science fiction sitcom Futurama, Leela offers her friend Fry an unusual housewarming gift: a bonsai tree sprouting tiny bananas, melons and plums.
“It’s a miniature fruit salad tree,” she explains. Here’s the thing: fruit salad trees are real. In Australia, James and Kerry West grow and sell four types of fruit salad trees, each of which bears several different kinds of fruit. Stone fruit salad trees grow peaches, plums, nectarines, apricots and peachcots. Threatened Trees. Your Memory May Be Edited. Our memories are inaccurate, more than we’d like to believe.
And now a study demonstrates one reason: we apparently add current experiences onto memories. Study subjects examined the location of objects on a computer screen against a background of an underwater ocean scene. Researchers then showed the subjects a fresh screen with a different background, this time a photo of farmland. And the subjects had to place an object in the same position it was in on the original screen. And they always placed the object in the wrong position.

John McNally's top 10 true or false science facts. My latest book Infinity Drake and the Sons of Scarlatti is the first in a new series of adventure thrillers in which the hero, Finn, gets caught up with his mad scientist uncle in a secret race to destroy an escaped bio-weapon – the Scarlatti Wasp – before it destroys life on earth.
Just another day in the life of an average 12-year-old. But… a pitiless trillionaire terrorist sabotages the project and Finn gets shrunk to 9mm and finds himself way behind enemy lines with a couple of soldiers and bunch of weapons – missing, presumed dead. The thrill-a-minute consequences contain some stunning action and some stunning science. But how much of that science is fiction and how much fact? Check out my top 10 true or false crazy science "facts" and see how if you know the difference between them! All trees need good care to grow well. Many trees planted by farmers never grow to maturity due to lack of proper management.
Baobab | Issue 62 | June 2011 The rainy season is also the time for planting trees. The first step in any tree planting exercise is to know the types of trees to be planted in every part of the farm. A wise farmer should have a variety of trees in their farm. These can include fodder trees, fruits trees and even trees to provide the farm with shade, firewood and timber in the future. ‘At Berkeley,’ a Documentary by Frederick Wiseman.

Sound, light and water waves and how scientists worked out the mathematics. You're reading these words because light waves are bouncing off the letters on the page and into your eyes.
The sounds of the rustling paper or beeps of your computer reach your ear via compression waves travelling through the air. Waves race across the surface of our seas and oceans and earthquakes send waves coursing through the fabric of the Earth. As different as they all seem, all of these waves have something in common – they are all oscillations that carry energy from one place to another. The physical manifestation of a wave is familiar – a material (water, metal, air etc) deforms back and forth around a fixed point.
Think of the ripples on the surface of a pond when you throw in a stone. Sound waves are known as "longitudinal" because the medium in which they travel – air, water or whatever else – vibrates in the same direction as the wave itself. The one-dimensional wave equation (pictured) describes how much any material is displaced, over time, as the wave proceeds.

Plants and the Human Brain - Why humans think like insects. Similarities between human and insect brains could be the reason why humans are attracted to plant-derived chemicals, such as tea, coffee, tobacco and drugs, according to a new book.
Professor David Kennedy, of Northumbria University, Newcastle, believes his new book, Plants and the Human Brain, answers the question as to why human brains are affected by plant chemicals. Despite many studies into how plant-derived chemicals interact with the brain and affect our behaviour, mood, mental and physical functions, there has been little research into why these chemicals have these effects at all. Professor Kennedy, Director of Northumbria University’s Brain Performance and Nutrition Research Centre, believes that similarities between human and insect brains can explain why humans are affected by and, in some cases, attracted to plant-derived chemicals.

Plants use 'unusual' microbial-like pathway to make essential amino acid. January 8, 2014 WEST LAFAYETTE, Ind. - Purdue University researchers have discovered a microbial-like pathway in plants that produces phenylalanine, an amino acid that is a vital component of proteins in all living organisms.
Plants mainly synthesize phenylalanine through a chain of chemical reactions that converts the organic acid arogenate to phenylalanine. But Purdue researchers demonstrated that plants also use an alternative pathway found in most microorganisms to make phenylalanine from phenylpyruvate. "Now that we have genetic evidence that this pathway exists in plants, this opens up many exciting possibilities for metabolic engineering," said Natalia Dudareva, distinguished professor of biochemistry. "This alternative pathway provides a whole new avenue to synthesize phenylalanine. " Phenylalanine is an aromatic amino acid that serves as a building block for many compounds essential to plant structure, reproduction, defense and communication.
