Life 'Not as We Know It' Possible on Saturn's Moon Titan

March 2, 2015 11:31 am | by Anne Ju, Cornell University | News | Comments

Liquid water is a requirement for life on Earth. But in other, much colder worlds, life might exist beyond the bounds of water-based chemistry. Taking a simultaneously imaginative and rigidly scientific view, chemical engineers and astronomers offer a template for life that could thrive in a harsh, cold world — specifically Titan, the giant moon of Saturn.

Seven Myths about Scientists Debunked

February 19, 2015 2:07 pm | by Jeffrey Craig and Marguerite Evans-Galea, Murdoch Childrens Research Institute | Articles | Comments

As scientific researchers, we are often surprised by some of the assumptions made about us by those outside our profession. So we put together a list of common myths we and our colleagues have heard anecdotally regarding scientific researchers.

Data Storage for Eternity: Encapsulated DNA-encoded Information Expected to Survive a Million Years

February 13, 2015 3:36 pm | by Angelika Jacobs, ETH Zurich | News | Comments

How can we preserve our knowledge today for the next millennia? Researchers have found a way to store information in the form of DNA, preserving it for nearly an eternity. As encapsulation in silica is roughly comparable to that in fossilized bones, researchers could draw on prehistoric information about long-term stability and calculate a prognosis: through storage in low temperatures, DNA-encoded information can survive.

Molecular Warfare: Researchers Discover Viral "Enigma Machine"

February 4, 2015 2:21 pm | by University of Leeds | News | Comments

Researchers have cracked a code that governs infections by a major group of viruses, including the common cold and polio. The unnoticed code had been hidden in plain sight in the sequence of the ribonucleic acid (RNA) that makes up this type of viral genome. But researchers have unlocked its meaning and demonstrated that jamming the code can disrupt virus assembly. Stopping a virus assembling can stop it functioning.

Pope Francis, who pledged on the day of his installation as pontiff to make the environment a priority, is drafting a highly anticipated encyclical on ecology and climate change. Environmentalists are thrilled by the prospect of a rock-star pope putting his moral weight behind efforts to curb global warming. Francis said he wanted the document to be released in time to be read before the next round of U.N. climate treaty talks in Paris.

By analyzing the light of hundreds of thousands of celestial objects, astronomers have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars, called diffuse interstellar bands. DIBs have been a mystery ever since they were discovered in 1922 — exactly which of the many thousands of possible molecules are responsible for these features?

By Any Other Name: The Central Role of Informatics in STEM Education

January 9, 2015 3:05 pm | by William Weaver, Ph.D. | Blogs | Comments

The human lament that things in the past were much simpler is an accurate observation made from the perspective of riding along an exponentially increasing complexity curve. Examining the present or looking into the future can be a confusing torrent of concepts, vocabulary and technologies that appear to be spiraling out-of-control. At the First IEEE Integrated STEM Education Conference, Professor Steve Zilora reflected on this increase...

Iron Sun: Not a Rock Band, but a Key to Stars’ Energy Transmission

January 6, 2015 12:16 pm | by Sandia National Laboratories | News | Comments

Working at temperatures matching the interior of the sun, researchers have been able to determine, for the first time in history, iron’s role in inhibiting energy transmission from the Sun's center to near the edge of its radiative band. Because that role is much greater than formerly surmised, the experimentally derived amount of iron’s opacity helps close a theoretical gap in the Standard Solar Model, used to model the behavior of stars.

NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill. Researchers used Curiosity’s onboard Sample Analysis at Mars laboratory a dozen times in a 20-month period to sniff methane in the atmosphere. During two of those months, four measurements averaged seven ppb.

There are a variety of roles for informatics in predictive analytics...

Mystery Deepens: Where Did Earth's Water Come From?

The mystery of where Earth's water came from got murkier on December 10, 2014, when some astronomers essentially eliminated one of the chief suspects: comets. Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind.

Earth’s Water is Older than the Sun

Water was crucial to the rise of life on Earth and is also important to evaluating the possibility of life on other planets. Identifying the original source of Earth’s water is key to understanding how life-fostering environments come into being and how likely they are to be found elsewhere. New work has found that much of our Solar System’s water likely originated as ices that formed in interstellar space.
