Whether working in the laboratory or simply locating parts for our recommended holiday gift guide kits, eventually many of you are going to be attempting to hunt down electronic components or information on them. Unfortunately, the days when you could just run over to RadioShack and pick-up a diverse pile of electronic components are long gone. However, all is not lost...
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.
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.
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...
Women lag behind men in the lucrative computer science and technology industries, and one of the possible contributors to this disparity is that they’re less likely to enroll in introductory computer science courses. However, a study of 270 high school students shows that three times as many girls were interested in enrolling in a computer science class if the classroom was redesigned to be less “geeky” and more inviting.
They're among the most powerful tools for shedding new light on cancer growth and evolution, but mathematical models of the disease for years have faced an either/or standoff. Models that capture spatial aspects of tumors typically don't study genetic changes. Non-spatial models more accurately portray evolution, but not 3-D structure. Researchers have developed the first model of that reflects both 3-D shape and genetic evolution.
Buzz Aldrin is teaming up with Florida Institute of Technology to develop a master plan for colonizing Mars within 25 years. The second man to walk on the moon took part in a signing ceremony at the university. The Buzz Aldrin Space Institute is set to open this fall. The 85-year-old Aldrin, who followed Neil Armstrong onto the moon's surface on July 20, 1969, will serve as a research professor of aeronautics.
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.
