Da Vinci’s Huge Horse Statue Proven Feasible
“‘Il Cavallo,’ the huge equine statue Leonardo Da Vinci never got to make, wasn’t plagued by technical problems as was widely believed, a new multidisciplinary research has revealed.
On the contrary, Da Vinci’s plan for the largest equestrian statue in the world was a perfectly feasible project which, if completed, would have probably been his greatest legacy, more than ”The Last Supper” or any other work.
Commissioned in 1482 by Lodovico Sforza, duke of Milan, in honor of his father Francesco, the massive bronze horse took Leonardo 17 years of research, but was never completed.
Indeed, when the full-scale clay model was finally ready to be cast in a single operation in 1499, all the needed bronze was used to make cannons for an imminent war against the King of France.
The molds were lost and the clay model was reduced to rubble by the invading French soldiers.
Although Leonardo never stopped mourning the ‘horse-that-never-was,’ engineers have always believed the daring plan to make the largest single-pouring cast ever would have failed because of technical problems.”

Real-Life Flat Earthers Still Continue To Believe
“Daniel Shenton should be the most irrational man in the world. As the new president of the Flat Earth Society, you’d imagine he would also think that evolution is a scam and global warming a myth. He should argue that smoking does not cause cancer and HIV does not lead to Aids.
Yes, that Flat Earth Society, a group that has become a living metaphor for backward thinking and a refusal to face scientific facts. Yes, it is still going, and no, this isn’t an early April fool.
In fact, Shenton turns out to have resolutely mainstream views on most issues. The 33-year-old American, originally from Virginia but now living and working in London, is happy with the work of Charles Darwin. He thinks the evidence for man-made global warming is strong, and he dismisses suggestions that his own government was involved with the 9/11 terrorist attacks.”

How Your Brain Tells Time
“In the middle of your brain, there’s a personal assistant the size of a grain of rice. It’s a group of about 20,000 brain cells that keeps your body’s daily schedule.
Partly in response to light signals from the retina, this group of neurons sends signals to other parts of the brain and the rest of the body to help control things like sleep, metabolism, immune system activity, body temperature and hormone production on a schedule slightly longer than 24 hours.
Daniel Forger, a mathematics professor at the University of Michigan who uses math to study biological processes, wants to understand this brain region, called the suprachiasmatic nucleus (SCN) in excruciating detail. He is building a mathematical model of the entire structure that he thinks will shed important light on our circadian rhythm, and perhaps lead to treatments for disorders like depression and insomnia, and even diseases influenced by the internal clock like heart disease, Alzheimer’s and cancer.”

One Physicist Hunts for the Ultimate Theory
One way to get noticed as a scientist is to tackle a really difficult problem. Physicist Sean Carroll has become a bit of a rock star in geek circles by attempting to answer an age-old question no scientist has been able to fully explain: What is time?
Here at the annual meeting of the American Association for the Advancement of Science where he gave a presentation on the arrow of time, scientists stopped him in the hallway to tell him what big fans they were of his work.
Carroll sat down with Wired.com on Feb. 19 at AAAS to explain his theories and why Marty McFly’s adventure could never exist in the real world, where time only goes forward and never back.

John Bramblitt – the blind painter
Most artists would be upset if their vision started to go. John Bramblitt was the opposite – he saw it as a challenge and used art as an outlet for his feelings. He paints with his fingers and feels the shapes using “slick paint” – a medium that dries very quickly so he can feel the shapes.
His art is truly incredible, the images are powerful and striking and considering his condition looking at them is quite moving. This small documentary is featured on his site along with his artwork – do check it out.
Makeup Girl Is A Living, Breathing Painting
“Looks like a real nice late 19th century painting, doesn’t it? But in reality, it’s a real girl wearing body-paint, and standing against a painted background.
‘Makeup Girl‘ is a very clever advertisement spotted, and photographed by Peter Kun Frary, in front of a MAC cosmetics shop, in Hawaii. The girl is a really well painted model, posing against a painted background. Now, you might think she’s naked, but she is wearing strips of cloth in all the right places.”

Extreme Breath-Holding: How It’s Possible
“A Swiss freediver held his breath underwater for 19 minutes and 21 seconds, according to news reports this week. The gasp-inducing feat beat the previous world record by 19 seconds, and blew away the record of 17 minutes and four seconds that magician David Blaine set on Oprah Winfrey’s talk show in 2008.
For most ordinary humans, all that breath-holding can be hard to fathom. The feat might also bring up some basic questions about biology. For example: Is it really possible to survive without inhaling for that long? And is it healthy?
“It is, as a matter of fact, possible — with certain tricks,” explained Claes Lundgren, a physiologist at the University of Buffalo School of Medicine in New York.
It is probably not, however, good for you, and consequences can be deadly.”

Volcano Chaser Braves Eruptions For Stunning Pictures
“Most people would think themselves unlucky if they passed a volcano as it erupted, but this counts as a good day at the office for one photographer.
Martin Rietze is part of a select group of volcano-chasers who seek out the exploding phenomena, and braves huge electric storms and boiling lava to get the perfect shots.
The 45-year-old travels around the world’s volcano hotspots, from Costa Rica to Italy, in his pursuit of Earth’s greatest fiery spectacle.”

In Darwin’s Shadow
Relatively few peple are aware that alongside Charles Darwin, another Scientist was busily working with the idea of natural selection. Alfred Russell Wallace not only spent even ore time than Charles Darwin collecting specimens, but pushed Darwin into publishing his Theory of Evolution by writing up his own findings on natural selection.
While Darwin has become a posthumous champion of skeptics, Wallace dabbled in spiritualism and pseudoscience. His ideas of natural selection also differed quite a bit from Darwin’s, as this biography shows.
