Science & Technology
My “aha” moment occurred in 2004 when, as a junior at the University of Illinois at Chicago, double majoring in physics and engineering, a research paper seized my interest. It was about the role that diamond could play as an electronics material — vastly uncharted territory at the time. I recognized then that diamond technology could spark a seismic change in the electronics industry and I knew I wanted to play a role in making diamond semiconductor a reality.
Believe it or not, scientists aren't yet finished discovering new ways to 3D print body parts. A team at the Feinstein Institute for Medical Research has developed a 3D printing technique that lets them produce cartilage for repairing damaged tracheas, better known to you and I as windpipes.
IBM quit making PCs in 2005, and it quit making servers last year. But it looks like Big Blue will keep pumping out its mainframes forever.
Researchers at Northwestern University and the University of Illinois at Urbana-Champaign have developed a simple new fabrication technique to create beautiful, complex 3D micro- and nanostructures with advantages over 3D printing for a variety of uses.
Ever since exoplanets were first discovered in the 1990s, astronomers have dreamed of finding an Earth-like planet amongst the stars. Better detection techniques have allowed us to find smaller and smaller exoplanets. But when we spot a planet beyond our Solar System, does “Earth-sized” really mean “Earth-like?” A new study presented at this week’s American Astronomical Society meeting shows that the smallest exoplanets are much more likely to be similar to Earth than we thought.
It’s been two days since AirAsia Flight 8501 disappeared over the Java Sea, and still there’s no sign of the missing plane or the 162 people aboard. It is, of course, all but impossible to know at this point just what went wrong, but we do know the flight’s planned route to Singapore would have taken it through clusters of thunderstorms, and we know the crew moved west of their course to avoid clouds.
The 3-D printer being used by astronauts on the International Space Station recently reached its second big milestone—it was employed to print a usable tool after a data file was uploaded from Earth that gave the printer the specifications and directions for how to produce the tool.
2014 brought more attention to 4K and curved displays than on 3D and active glasses. Toshiba launched a 4K laptop in April, LG sells a 4K curved TV, and recently Samsung introduced a 4K curved PC monitor. Apple took it a step further and released a 5K iMac refresh, followed by Dell with a 5K "smart desk", and Samsung promised to release a phone with a foldable display in 2015. Toshiba is also following the 'retina' trend and is looking to bring smooth 8K broadcasts by 2020.
People hold beliefs for a complex variety of reasons. Some of these beliefs may be based on facts, but others may be based on ideas that can never be proved or disproven. For example, people who are against the death penalty might base their belief partly on evidence that the death penalty does not reduce violent crime (which could later be shown to be false), and partly on the notion that the death penalty violates a fundamental human right to life. The latter is an unfalsifiable belief, because it can’t be changed purely by facts.
NASA rover Curiosity is beavering away up on Mars, examining rocks, drilling holes, checking out the weather -- but it's not just up there to look at the planet's hospitability for humans. It's also looking for conditions favourable for life; not now, but in the past, when Mars may have been home to extraterrestrial microbes.
But maybe the answer is right here on Earth, after all -- in the form of a meteorite.
