Five must-read stories from the past week include exploring the limits of life in the Universe; the fastest moving glacier in the world shedding a significant iceberg; Stephen Hawking's new solution to the black hole mystery; one of the great disputes of 20th-century physics: the story of Philipp Lenard and Albert Einstein; and solving the ancient lunar fire fountain mystery.

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.
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.
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.
GENCI, the high performance computing agency in France, and IBM announced a collaboration aimed at speeding up the path to exascale computing — the ability of a computing system to perform at least one exaflop, or a billion billion calculations, in one second. Currently, the fastest systems in the world perform between 10 and 33 petaflops, or 10 to 33 million billion calculations per second — roughly one to three...
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.
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.
Joseph Frederick Traub, a leading figure in developing the field of computational complexity, passed away August 24, 2015, in Santa Fe. At the time of his passing Traub, 83, was the Edwin Howard Armstrong Professor of Computer Science at Columbia University and an external professor of the Santa Fe Institute (SFI). Traub spent his career at the frontiers of applied mathematics and computer science.
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.
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.
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.
Using quantum mechanics as the basis, computer scientists, physicists and chemists are working together to produce simulations of the molecule in which photosynthesis occurs. They have executed an OCTOPUS software package in the fastest supercomputers in Europe and, after incorporating various improvements, they have carried out the biggest simulations made in this field by efficiently using thousands of processors.
Ultimately, Katrina was responsible for 1,833 deaths and damage estimated at $151 billion, including $75 billion in the New Orleans area and along the Mississippi coast. Over the past decade, researchers have been working steadily to collect and analyze data on the storm’s aftermath, including coastal change, science for recovery and restoration, and census data.
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.
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.
This 100X photo shows phosphofructokinase, a kinase enzyme that phosphorylates fructose 6-phosphate in glycolysis. Glycolysis is a pathway that uses glucose to maintain a steady amount of adenosine triphosphate, the major energy carrier in living cells. It was designated an Image of Distinction in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope.
