The Chalmers system uses satnav signals to measure sea level

Measuring sea level is not only an invaluable tool for pilotage, navigation, aeronautics, cartography, sea charting, and geology, it’s also a fundamentally important metric for measuring possible evidence of climate change, and for measuring the direction, extent and rate of such change. Johan Löfgren and Rüdiger Haas of Chalmers University in Sweden have developed a new way of measuring sea level that uses satnav signals for constant, real-time monitoring that promises new insights into many fields, including climate change.  Read More

GE Honda Aero Engines has shipped the first pair of production HF120 jet engines for the H... The Hondajet has passed another milestone on its way to entering commercial service. After completing FAA certification testing last year, the executive jet's first pair of production HF120 jet engines have been shipped.  Read More

GE has found a way to extend wind turbine rotor blades without replacing them

Sometimes progress can be its own worst enemy, with early adopters being stuck with obsolete equipment that leaves them with the choice of living with out-dated technology or an expensive replacement. The green energy field isn’t immune to this, and as part of a US$2 million renewable energy project, GE has developed a way to make smaller, less efficient wind turbines into bigger more efficient ones with a bit of plastic (or carbon composite) surgery.  Read More

The Cardio First Angel is a simple mechanical device designed to help users provide treatm...

Performing cardiopulmonary resuscitation (CPR) in the first 15 minutes following a heart attack can be a literal lifesaver, greatly increasing the victim's chances of survival. However, many people aren't trained in CPR and even those who are can be hesitant to step up in the vital first minutes that can mean the difference between life and death. The Cardio First Angel CPR coach is a simple mechanical device that guides even an untrained person in properly administering CPR.  Read More

NASA’s Rodent Habitat module (Image: NASA/Dominic Hart)

Attention space rats and astromice, NASA is sending new, posher rodent habitats to the International Space Station (ISS). The high-tech cages will first will fly in August aboard an unmanned SpaceX Dragon cargo ship and are part of an extensive study on the effects of weightlessness on prolonged space voyages.  Read More

Computer simulation of a wing flex module

We tend to think of aeronautical engineering as having left the birds standing still sometime around the First World War, but since jet fighters can’t perch and quadcopters can’t snag salmon out of a stream, we still have a few things to learn. Taking a couple of pages from the avian playbook, Fraunhofer Institute for Electronic Nano Systems (ENAS) and its partners are developing wing flaps for airplanes that change shape like a bird’s wing for greater efficiency.  Read More

Large, fresh crater surrounded by smaller craters (Image: NASA)

There are millions of impact craters all over the Solar System, but direct evidence of the massive collisions that form them is very hard to come by – and therefore very valuable. While carrying out its routine monitoring of the weather on the Red Planet, the Mars Color Imager (MARCI) on NASA’s Mars Reconnaissance Orbiter (MRO) has inadvertently snapped before and after images of the largest fresh meteor impact crater found anywhere in the Solar System.  Read More

The parallel ordering of liquid crystals make them near-frictionless lubricants (Image: Mi...

The world uses tens of millions of tons of lubricant every year, from the smallest part of a micro-precision instrument to the expansion rollers on the largest bridges. Most are oil based, though others use powders, and even metals, and it’s been that way for decades. That could be changing as the Fraunhofer Institute for Mechanics of Materials, Nematel GmbH, and Dr. Tillwich GmbH have developed a new class of lubricants that are based on liquid crystals instead of oil. According to Fraunhofer, this is the first fundamentally new lubricant developed in twenty years.  Read More

Julian Sharpe, President of Survival Capsule LCC

The 2011 Tohoku earthquake and the tsunami that followed count as one of the worst disasters of the 21st century. When it struck off the southern coast of Japan with a force of magnitude 9, it was the most powerful ever to hit Japan, and the tsunami with a maximum height of 40.5 m (133 ft) resulted in 15,885 deaths, 6,148 injured, and 2,623 people missing. In anticipation of a similar disaster, Survival Capsules LCC of Mukilteo, Washington has developed a steel and aircraft-grade aluminum sphere designed to protect against both fire and flood. Gizmag paid a visit to the company to learn more about it.  Read More

Methanogens prepared to be exposed to Martian conditions

Since the first Mariner probes reached the Red Planet in the 1960s, it’s become clear just how very alien Mars is and how hard it is to find parallel examples of possible Martian life on Earth. However, it’s not impossible. Rebecca Mickol, a doctoral student in space and planetary sciences at the University of Arkansas, has discovered that two species of methane-producing bacteria can live in the harsh conditions on Mars, and may aid in the search for life there.  Read More
