You might agree that the complex design in a snowflake appears almost comparable to a work of art. Do you know how that tiny frozen masterpiece comes to life, though? If you're like me, you may never have witnessed a complete representation of that journey from cloud to ground before.

The trip isn't as simple as you think. … Read more

Have you ever seen billions of dollars in gold bars? A video -- made in the name of science -- gives a glimpse into the massive gold reserves at the Bank of England.

University of Nottingham professor Martyn Poliakoff loves the elements. The eccentric science wizard works with others on a popular Web site and YouTube channel known as The Periodic Table of Videos; one latest video focuses on one of the most valuable elements in existence -- gold. … Read more

After a record-breaking 9,000-mile journey across the ocean, a small autonomous robot recently arrived in Australia having collected and transmitted a wealth of scientific data that could lead to a better understanding of the world's seas.

On November 17, 2011, a Silicon Valley startup called Liquid Robotics launched four of its Wave Glider robots from San Francisco, two of which were heading toward Australia and the other two on their way to Japan. The hope was that the Wave Gliders, which are designed to travel across the globe without fuel or outside propulsion, would set the Guinness World … Read more

In an ongoing effort to restructure its Mars exploration program in the wake of deep budget cuts announced earlier this year, NASA announced plans Tuesday to send a new $1.5 billion rover to the red planet in 2020 based on the design of the agency's hugely successful Curiosity.

The as-yet-unnamed rover is the second new Mars mission announced in the wake of the budget cuts that will be built using already-existing designs, a money-saving architecture agency officials say is more in line with current funding reality.

"The challenge to restructure the Mars Exploration Program has turned from … Read more

Despite widespread speculation about a potentially significant discovery on Mars, the Curiosity rover's first detailed look at a Martian soil sample with an instrument capable of detecting organic compounds hasn't found any "definitive" signs of materials that play key roles in biological processes on Earth, scientists said Monday.

While the rover's Sample Analysis at Mars, or SAM, instrument detected signs of an oxygen-chlorine compound -- perchlorate -- and trace amounts of chlorinated methane compounds, which contain carbon, researchers say more tests are needed to make sure the carbon originated with the sample and was not … Read more

Buffeted by ethereal whirlwinds and twisters, the Curiosity Mars rover is wrapping up initial soil analysis operations at a sandy drift where it's been parked for more than a month, project scientists said today. The rover is now being prepared to move on in search of suitable targets for a compact rock drill, the final major sample acquisition system to be tested.

Ashwin Vasavada, the deputy project scientist for the Mars Science Laboratory rover at the Jet Propulsion Laboratory in Pasadena, Calif., told reporters that Curiosity's robot arm had completed five scoops of martian soil, using the sandy … Read more

As a child, I used to concentrate really hard on things like pencils and pebbles, trying to get them to budge with the sheer power of my mind. It never worked, but technology is getting us a little closer to the mind control dream. The Muse brainwave-sensing headband from Interaxon is a step in the right direction.

The Muse uses two sensors on the forehead and two behind the ears. You wear it positioned kind of like a pair of glasses. It measures your brainwaves and sends the information to a smartphone or tablet. Viewing that data in real time can show you if your mind is wandering, if you're relaxed, or if you're in a state of intense concentration.… Read more

Pick one: "Evolution of nanostructural architecture in 7000 series aluminum alloys during strengthening by age-hardening and severe plastic deformation," or "A super-alloy is born: The romantic revolution of Lightness & Strength." I'm betting you're going for the romantic revolution.

"A super-alloy is born" is the interpretive dance version of a Ph.D. thesis by Peter Liddicoat, a materials scientist at the University of Sydney in Australia. It's also the grand prize winner of Science magazine's Dance Your Ph.D. contest. The contest challenges Ph.D. students in the sciences to create interpretive dance videos to explain their theses.… Read more

Countless childhood dreams dissolved today upon the news that the calculated half-life of DNA figures out to around 521 years, all but invalidating the chances of a real-life "Jurassic Park."

The DNA fact-finding project involved a team of palaeogeneticists testing 158 leg bones belonging to three species of extinct giant moa birds ranging from 600 to 8,000 years old.

After running a series of comparisons between the age of the various bones and DNA degradation within each specimen, the researchers estimated that DNA's half-life works out to about 521 years after being kept in a swamp with an average temperature of 13.1 Celsius (55 Fahrenheit). Even a more ideal preservation temperature of minus 5 Celsius (23 Fahrenheit) would only result in readable DNA from specimens up to 1.5 million years old, meaning there is no possible way we can see a 65-million-year-old T-Rex waving its tiny arms about in this time frame. … Read more
