As the possible ‘comet of the century’ approaches its date with the Sun (Nov. 28th, 2013), the chances of its break-up will increase exponentially. The comet is not on a trajectory to hit the Earth. What will happen to pieces that may break away?
We all know it’s awesome, and we could watch Chris Hadfield sing all day, but do you know about the awesome science that’s being done on the International Space Station?
The winners of the 2013 Google Science Fair have been announced, and the prizes this year go to some truly amazing young scientists. Trace shows us the inventions they came up with, and introduces us to the high schooler who took home the top prize.
Uncrackable quantum encryption codes could be finding their way to mainstream networks. The new system, developed by Toshiba’s Cambridge Research Laboratory, allows dozens of users to share one network. Usually, each computer has to have an expensive and complicated transmitter and detector, as well as a fibre link. The networks work by transferring single photons of light in a sequence. If they’re observed en route, they change, making the code uncrackable in the laws of physics.
With sensitive instruments and some creative translations, astronomers can derive the sounds of a silent universe. Scientific American contributor Sophie Bushwick explains.
Does the order you’re born in really affect the kind of person you grow up to be? Trace explains if there’s really the impact people say there is.
Dr James Grime on the Pisano Period – a seemingly strange property of the Fibonacci Sequence.
About 10,000 years ago, hunter-gatherers, aided by rudimentary agriculture, moved to semi-permanent villages and never looked back. With further developments came food surpluses, leading to commerce, specialization and, many years later with the Industrial Revolution, the modern city. Vance Kite plots our urban past and how we can expect future cities to adapt to our growing populations.
Gossip is something that’s been around for ages- it’s even talked about in the Bible! Trace explains how gossip and rumor have plain an important role on human evolution and its impact on society.
You know what’s funny? Why people laugh. Hank talks about the science of laughter: what makes us laugh, what purpose it serves, and even what it can tell us about our mental and physical health. Hilarious!
Most people sit between 5 and 12 hours a day. Depending on your job, you are probably sitting more than you are sleeping. Watch to find out how sitting is slowly killing you, and what you can do about it,
Extraterrestrial real estate is land on other planets or natural satellites or parts of space that is sold either through organisations or by individuals. Ownership of extraterrestrial real estate is not recognised by any authority. Nevertheless, some private individuals and organisations have claimed ownership of celestial bodies, such as the Moon, and are actively involved in “selling” parts of them through certificates of ownership termed “Lunar deeds”, ”Martian deeds” or similar. These “deeds” have no legal standing.
In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean — from the deepest trenches to the remains of the Titanic — marine biologist David Gallo explores the wonder and beauty of marine life.
When we make a recording of our own voice then play it back, we are hearing it more or less as other people do. The sound waves travel as a series of vibrations through the air and meet our ear drum. The ear drum in turn sets three tiny bones vibrating – the incus, malleus and the stapes and they send vibrations into the cochlea. The cochlea translates the vibrations into nerve signals and those are sent to the brain. Why then does that sound so different to what we perceive as our own voice?
Jade bi (discs), from China, that resemble modern-day CD’s or donuts, and date to the late Neolithic Period, Liangzhu culture (ca. 3300-2250 BC) remain a mystery. Researchers at the Smithsonian’s Freer and Sackler galleries in Washington, D.C., are among those who have studied the bi.
