Future - Science & Environment - Drake equation: How many alien civilizations exist?
Are we alone? It is a question that has occupied mankind for centuries. Today, we live in an age of exploration, where robots on Mars and planet-hunting telescopes are beginning to allow us to edge closer to an answer. While we wait to establish contact, one technique we can use back on Earth is an equation that American astronomer Frank Drake formulated in the 1960s to calculate the number of detectable extraterrestrial civilizations may exist in the Milky Way galaxy. It is not a rigorous equation, offering a wide range of possible answers. Instead it is more a tool used to help understand how many worlds might be out there and how those estimates change as missions like Kepler, a telescope that is currently searching for Earth-like planets, begin to discover more about our universe.

The Massey Experience Welcome to The Massey Experience, an online exploration of the ideas, themes, theories and characters that form Neil Turok's 2012 Massey Lectures The Universe Within: From Quantum to Cosmos. The Massey Experience is an immersive, evolving companion to Neil's Massey Lectures which aired on CBC Radio's IDEAS in November 2012. The story is a journey from quantum to cosmos: where we've come from, where we're going and what we've learned along the way. Neil argues that we're on the cusp of yet another major transformation: a coming quantum revolution that will supplant our current digital age. It's the story of science and technology, but it is also the story of who we are: amazing creative humans.

Harvard cracks DNA storage, crams 700 terabytes of data into a single gram A bioengineer and geneticist at Harvard’s Wyss Institute have successfully stored 5.5 petabits of data — around 700 terabytes — in a single gram of DNA, smashing the previous DNA data density record by a thousand times. The work, carried out by George Church and Sri Kosuri, basically treats DNA as just another digital storage device. Instead of binary data being encoded as magnetic regions on a hard drive platter, strands of DNA that store 96 bits are synthesized, with each of the bases (TGAC) representing a binary value (T and G = 1, A and C = 0). To read the data stored in DNA, you simply sequence it — just as if you were sequencing the human genome — and convert each of the TGAC bases back into binary.

12 Pictures of Space You Won't Believe Aren't Photoshopped Look, we all know that space is the final frontier, that space is cold and unforgiving and that in it, nobody can hear you scream. But what you might not know is that, when it thinks nobody is looking, space puts on a frilly dress, covers its forearms in honey and spins around until it falls over ... because space is just flat-out crazy as hell. Oh, don't take our word for it or anything; we have photographic evidence. #12.

Dr. Steven Greer’s Response to Stephen Hawking’s Comment on Aliens « News from Behind the Scenes by Dr. Stephen Greer, The Disclosure Project, April 26, 2010 Published here: Thursday, April 29, 2010 @ 5:44 AM Dr. Frequently Asked Questions in Cosmology Tutorial : Part 1 | Part 2 | Part 3 | Part 4 | Age | Distances | Bibliography | Relativity What is the currently most accepted model for the Universe? The current best fit model is a flat ΛCDM Big Bang model where the expansion of the Universe is accelerating, and the age of the Universe is 13.7 billion years. Back to top. What is the evidence for the Big Bang?

A Trip Through The Universe - “For You To Enjoy And Share With Friends” - Another trip through the Universe travelling at the speed of light. Again it gives you the perspective of actually tiy we are and how vast the Universe actually is. The Milky Way is a huge city of stars, so big that even at the speed of light, it would take 100,000 years to travel across it.

Top 10 Most Important Discoveries in Astronomy Astronomy is the cool, sexy field of the scientific world. Sure, biologists and chemists are out there curing diseases or whatever, but they’re just so boring. Meanwhile, astronomers are busy showing us sweet pictures of distant planets and playing around with telescopes the size of buildings. How can you compete with that? Scientists Confirm that Plants Talk and Listen To Each Other, Communication Crucial for Survival When a South African botanist Lyall Watson claimed in 1973 that plants had emotions that could be recorded on a lie detector test, he was dismissed by many in the scientific community. However, new research, published in the journal Trends in Plant Science, has revealed that plants not only respond to sound, but they also communicate to each other by making "clicking" sounds. Using powerful loudspeakers, researchers at The University of Western Australia were able to hear clicking sounds coming from the roots of corn saplings. Researchers at Bristol University also found that when they suspended the young roots in water and played a continuous noise at 220Hz, a similar frequency to the plant clicks, they found that the plants grew towards the source of the sound. "Everyone knows that plants react to light, and scientists also know that plants use volatile chemicals to communicate with each other, for instance, when danger - such as a herbivore - approaches," Dr.

Top Story - CHANGES IN THE EARTH'S ROTATION ARE IN THE WIND - March 4, 2003 Because of Earth’s dynamic climate, winds and atmospheric pressure systems experience constant change. These fluctuations may affect how our planet rotates on its axis, according to NASA-funded research that used wind and satellite data. NASA’s Earth Science Enterprise (ESE) mission is to understand the Earth system and its response to natural and human-induced changes for better prediction of climate, weather and natural hazards, such as atmospheric changes or El Niño events that may have contributed to the affect on Earth’s rotation. “Changes in the atmosphere, specifically atmospheric pressure around the world, and the motions of the winds that may be related to such climate signals as El Niño are strong enough that their effect is observed in the Earth’s rotation signal,” said David A. Salstein, an atmospheric scientist from Atmospheric and Environmental Research, Inc., of Lexington, Mass., who led a recent study.

Kissing Hank's Ass "Effing the ineffable since 1996" Looking over my most recent articles I notice that they tend to be pretty negative. That's not really the kind of person I am. Or at least not the kind of person I want to be. So I thought it might be nice to get away from mocking religion for a while and instead talk about one of my heroes: Adam Savage. Adam Savage is the host of "Mythbusters," a science reality show on The Discovery Channel.

Fallacies  A fallacy is a kind of error in reasoning. The list of fallacies contains 209 names of the most common fallacies, and it provides brief explanations and examples of each of them. Fallacies should not be persuasive, but they often are. Best Images and Videos From 3-Mile-Wide Asteroid Toutatis' Flyby There was a great deal of excitement from yesterday’s cosmically close shave as 3-mile-wide asteroid 4179 Toutatis zipped by the Earth. If you missed the action, we’ve rounded up some of the best images and videos from the event. Toutatis is a long, irregularly shaped object that swings by Earth about once every four years, usually coming within a few million miles of our planet.
