NEW SATELLITE DATA REVEALS WHOPPING BOOST IN SHIPPING Maritime traffic on the world’s oceans has increased four-fold over the past 20 years, likely causing more water, air and noise pollution on the open seas, according to a new study quantifying global ship traffic. The research used satellite data to estimate the number of vessels on

A SISSA algorithm published in Science simplifies the categorization of data Experts use the expression big data to indicate huge amounts of information, such as those (photos, videos, texts, but also other more technical types of data) shared at any time by billions of people on computers, smartphones and other electronic devices. The present-day scenario

Antimatter propulsion is the Holy Grail of spaceflight. When matter and antimatter react, the energy produced is several billion times larger than the thermomechanical energy resulting from burning a kilogram of a hydrocarbon fuel. Now a high school student has developed a new magnetic exhaust nozzle that would double the velocity of an antimatter-powered rocket.

Are We Seeing The Real Future of Independent and Unrestricted Communications? On January 7, 2010 I was ushered into a small private dinner with Secretary Hillary Clinton at the State Department along with the inventor of Twitter, Jack Dorsey, Eric Schmidt, CEO of Google and a few others. We were there to talk about technology

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of

A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists. The creation pushes the boundaries of metamaterials – a new class of finely-engineered surfaces that perform nature-defying tasks. These materials have already shown remarkable results with light manipulation, allowing scientists to create a real-life version of Harry

Seagrass beds are so effective in protecting tropical beaches from erosion, that they can reduce the need for regular, expensive beach nourishments that are used now. In a recent article in the journal BioScience, biologists and engineers from The Netherlands and Mexico describe experiments and field observations around the Caribbean Sea. “A foreshore with both

Making large-scale “server farms” more energy efficient and allowing computers to start more quickly Researchers from North Carolina State University have developed a new device that represents a significant advance for computer memory, making large-scale “server farms” more energy efficient and allowing computers to start more quickly. Traditionally, there are two types of computer memory

DARPA wants robots that are able to eventually do many things humans can A headless humanoid robot clambers noisily through an obstacle course with the grim, unfeeling purpose of a terminator. Luckily, it’s just the latest video celebrating the official start of a U.S. military challenge to create robots that can work alongside humans in
