Art and Science Combine to Reveal Inner Workings of Our DNA

August 28, 2015 2:25 pm | by Kate Patterson, Garvan Institute and Susan Clark, Garvan Institute | Articles | Comments

How can cells that contain the same DNA end up so different from each other? That is not only a difficult question for science to answer, but also a challenging one to represent visually. It is also the question I posed at the start of my latest biomedical animation, called Tagging DNA, which visualizes the molecular mechanisms behind epigenetics.

Cyberlearning Tools Fuse Computational Modeling, Data Analysis to Improve Learning

August 28, 2015 11:33 am | by Aaron Dubrow, NSF | News | Comments

Back-to-school season is here and, in addition to chalkboards, desks and inspirational posters, today's students may be entering classrooms equipped with sensors, tablet computers and advanced simulation software — at least, if they are using a new cyberlearning tool called InquirySpace, which brings together a wide variety of educational technology innovations, enabling more fluid engagement in extended scientific inquiry.

Climate Change and Hurricane Katrina: What have We Learned?

August 28, 2015 11:10 am | by Kerry Emanuel, Massachusetts Institute of Technology | Articles | Comments

Three weeks and three days before Hurricane Katrina devastated New Orleans 10 years ago, a paper of mine appeared in Nature showing that North Atlantic hurricane power was strongly correlated with temperature of the tropical Atlantic during hurricane season, and that both had been increasing rapidly. Had Katrina not occurred, this paper would merely have contributed to the slowly accumulating literature on climate and hurricanes.

Chocolate Physics: How Molecular Simulation could Improve Texture and Aromatic Sensation

August 27, 2015 3:04 pm | by Institute of Physics | News | Comments

Lecithin is an ingredient that you’ve quite possibly never heard of, but one that plays a vital role in the production of chocolate. It’s never been clear how this ingredient works on a molecular level. Scientists have shown how the field of molecular dynamics — simulation on a molecular level — could be a valuable tool in understanding the part of the chocolate-making process where aromatic sensation, texture and mouthfeel are developed.

Because there is the potential for such a large amount of data to be collected during play, the focus on sports analytics is increasingly associated with what is referred to as big data.

Big Data can give Athletes the Winning Edge

August 27, 2015 2:30 pm | by Carmine Sellitto, Victoria University | Articles | Comments

Sport at the elite level has always adopted new technologies to capture data from players during play to better understand their performance and team’s result. Closely aligned with this is the practice of data analytics, and developments here tend to fall into two areas. One is refinement of existing technologies that measure activities. The other is data analysis tools that allow some meaning to be drawn from data collection.

Exploring the Limits of Life in the Universe

August 27, 2015 11:42 am | by Will Ferguson, Washington State University | News | Comments

Bizarre creatures that go years without water. Others that can survive the vacuum of open space. Some of the most unusual organisms found on Earth provide insights for planetary scientist Dirk Schulze-Makuch to predict what life could be like elsewhere in the universe. NASA’s discovery last month of 500 new planets near the constellations Lyra and Cygnus, in the Milky Way Galaxy, touched off a storm of speculation about alien life.

What would a Tsunami in the Mediterranean look Like?

August 27, 2015 11:02 am | by European Geosciences Union | News | Comments

Researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African plate slides underneath the Eurasian plate.

Novel New Technology may Illuminate Mystery Caves below Moon’s Surface

August 27, 2015 10:48 am | by Brian Mattmiller, University of Wisconsin-Madison | News | Comments

It's widely believed that the moon features networks of caves created when violent lava flows tore under the surface from ancient volcanoes. Some craters may actually be "skylights" where cave ceilings have crumbled. Since "lunar spelunking" expeditions aren't coming soon, the challenge is how to confirm the existence and dimensions of these caves with current remote imaging.

Big Data: Mapping the Geology of the World's Ocean Floor

August 26, 2015 4:26 pm | by University of Sydney | News | Comments

Scientists have created the world’s first digital map of seafloor geology. It is the first time the composition of the seafloor, covering 70 percent of the Earth’s surface, has been mapped in 40 years; the most recent map was hand-drawn in the 1970s. The map will help us better understand how oceans have responded, and will respond, to environmental change. It also reveals deep ocean basins to be much more complex than previously thought.

When Vaccine Data doesn’t Change Minds, Directing Attention to Risks is Effective

August 26, 2015 3:53 pm | by Diana Yates, University of Illinois | News | Comments

It might not be possible to convince someone who believes that vaccines cause autism that they don’t. Telling skeptics that their belief is not scientifically supported often backfires and strengthens, rather than weakens, their anti-vaccine views. But researchers say they have found a way to overcome some of the most entrenched anti-vaccine attitudes: Remind the skeptics — with words and images — why vaccines exist.
