Why do humans love to look at patterns? I can only guess, but I’ve written a whole book about new mathematical ways to make them. In Creating Symmetry, The Artful Mathematics of Wallpaper Patterns, I include a comprehensive set of recipes for turning photographs into patterns. The official definition of “pattern” is cumbersome; but you can think of a pattern as an image that repeats in some way...
COMSOL, a provider of multiphysics modeling and simulation software, announced new Focus and Training Sessions that will be featured at the 11th Annual COMSOL Conference, the world’s largest event for multiphysics simulation and application design. Each session is designed to provide attendees with an in-depth look at how to get the most out of modeling.
An astronaut aboard the International Space Station took this photograph of small island cays in the Bahamas and the prominent tidal channels cutting between them. For astronauts, this is one of the most recognizable points on the planet. The string of cays extends west from Great Exuma Island. Exuma is known for being remote from the bigger islands of The Bahamas, and it is rich with privately owned cays and with real pirate history.
This 40X photograph shows the oculomotor nerve of a transgenic Brainbow mouse (Mus Musculus). It was designated an Image of Distinction in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope and was taken using laser-scanning confocal microscopy and Brainbow neuroimaging.
Using a design approach which may enable the development of low-energy computer memory technologies, scientists have developed a new material that combines both electrical and magnetic order at room temperature. Researchers achieved this scientific advance by designed control of the distribution of the atoms within the solid state. This new material has implications for information storage and processing applications.
The more we find out about Pluto, the more perplexing it seems. For several weeks after its July 14 fly-by, NASA’s probe New Horizons was too busy doing science to transmit data to Earth. During that time we had to content ourselves with the few “taster” images that were beamed back immediately after it passed Pluto. However the probe has now begun the year-long process of transmitting its vast haul of fly-by data.
NASA is giving university and college students an opportunity to be part of the agency’s journey to Mars with the Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge. NASA’s Game Changing Development Program (GCD), is seeking innovative ideas for generating lift using inflatable spacecraft heat shields or hypersonic inflatable aerodynamic decelerator (HIAD) technology.
Modern digital cameras are equipped with an impressive array of functions — from autofocus and image stabilization to panoramas and high-definition video. Recently, a team of engineers from Duke University has unlocked a previously unrecognized 3-D imaging capability of modern cameras by simply repurposing its existing components.
Scientists have created a computational model that could change the way that researchers look at possibilities for an HIV-1 vaccine. They used a mathematical model to examine how broadly neutralizing antibodies coevolve with HIV. By simulating the co-evolution of multiple viral strains and antibody populations, Perelson and Luo show that broadly neutralizing antibodies emerge late in infection ...
In case you haven’t caught them yet, here’s a recap of his week’s most popular stories. What you should know about near field communications; physicists revealing that molecules made of photons may be possible; evocative high-def views of the iconic Pillars of Creation; researchers creating a magnetic wormhole, and successfully connecting two regions of space; and five myths about gravitational waves are all among the top stories.
Invisibility cloaks are a staple of science fiction and fantasy, from Star Trek to Harry Potter, but don’t exist in real life — or do they? Scientists have devised an ultra-thin invisibility “skin” cloak that can conform to the shape of an object and conceal it from detection with visible light. Although this cloak is only microscopic in size, principles behind the technology should enable it to be scaled-up to conceal macroscopic items.
This Sentinel-2A false color image shows agricultural structures in the Abruzzo region of central Italy. The varying shades of red and other colors across the entire image indicate how sensitive the satellite’s multispectral camera is to differences in vegetation cover and chlorophyll content. This is used to provide key information on plant health.
The 25th First Annual Ig Nobel Prize Ceremony took place on September 17, 2015, at Harvard University. This year’s ceremony introduced 10 new Ig Nobel Prize winners — each has done something that makes people laugh, then think. Winners traveled to the ceremony, at their own expense, from around the world to receive their prize from a group of “genuine, genuinely bemused Nobel Laureates,” in Harvard's historic and largest theater.
Robin Murphy is the master of disaster robots. After 9/11, she deployed small mobile robots to investigate the rubble. In the wake of Katrina, she sent UAVs to explore buildings. During Fukushima, she was part of a team that flew UAVs to determine radiation levels and inspect damage. And during the Ebola pandemic, she explored whether robots could help protect health workers from contagion in field hospitals in West Africa and the U.S.
Registering for SC15? You can sign up to mentor a student at the same time. If you plan to attend SC15, consider signing up as a mentor to help students get the most out of the conference and make a difference in their careers. Organized as part of Students@SC, the Mentor-Protégé Program is designed to support the growth of a vibrant HPC community by connecting newcomers at the SC conference with experienced conference attendees.
