Artist's impression of Theia colliding with Earth (Image: NASA/JPL)

There are a number of ideas about where the Moon came from, but, based on orbital mechanics, the accepted theory is that about 150 million years after the Solar System formed some 4.6 billion years ago, the primordial Earth was struck by an object the size of Mars called Theia. Out of the debris of this massive impact, the Moon was formed. Scientists at the University of Maryland (UMD) have for the first time found evidence to support this theory by analyzing the isotopic “fingerprints” of rock samples brought back by the Apollo astronauts.  Read More

We've only just begun to see the huge impact 3D-printing technology will have on manufacturing, and the aerospace industry is a prime example. Earlier this year we saw the first example of a 3D-printed jet engine, now GE has announced the first 3D-printed part certified by the US Federal Aviation Administration (FAA) for a commercial jet engine. The fist-sized T25 housing for a compressor inlet temperature sensor was fabricated by GE Aviation and will be retrofitted to over 400 GE90-94B jet engines on Boeing 777 aircraft.  Read More

The Vulcan rocket will use a reusable booster engine configuration

The United Launch Alliance (ULA) has entered the reusable launcher race with its Next Generation Launch System (NGLS), also known as the Vulcan rocket. This replacement for the current generation of launch systems will incorporate a rocket engine assembly that jettisons from the first stage and is snared in mid-air by a helicopter after reentering the Earth's atmosphere  Read More

The Dyson V6 Mattress is designed to remove dust mites and other microscopic particles

According to Dyson, bed mattresses contain anywhere between 10,000 and two million dust mites that churn out around 40 million droppings per day. To deal with the pesky critters and provide relief for allergy sufferers, the company has announced its handheld V6 Mattress cleaner, which packs HEPA filtration and is powered by the Dyson digital motor V6.  Read More

These days, it seems like every celebrity comes out with a cookbook at some point, and IBM's Watson supercomputer is no exception. The newly released Cognitive Cooking with Chef Watson includes 65 recipes, developed with the help of what's billed as "the world’s first cognitive cooking system", is the result of a three-year collaboration between IBM Research and chefs at the Institute of Culinary Education (ICE).  Read More

Falcon 9 making its landing attempt

Elon Musk's goal of achieving the first powered landing of a reusable booster had a close brush with success today as a SpaceX Falcon 9 rocket narrowly failed to survive a touchdown on the deck of a drone barge off the US east coast. The third landing attempt by the company came after the launch of the CRS-6 mission, which sent an unmanned Dragon cargo spacecraft to the International Space Station.  Read More

A remarkable scientific document went under the hammer today at Bonhams in New York. The rare handwritten manuscript by Alan Turing in which he made notes on symbolic logic and mathematics during the Second World War for sold for US$1,025,000.  Read More

A hand-sized tape cartridge of the new tape could hold the equivalent of 220 terabytes of ...

For many people, tape memory is a dead technology found only on reel-to-reel computers in old 1960s movies. However, it’s still a major storage medium and a new breakthrough by IBM Research and Fuji Film has produced a low-cost particulate magnetic tape with a record density of 123 billion bits of uncompressed data per square inch, which represents 88 times more capacity than 2012's LTO-6 tape cartridge.  Read More

Artist’s concept of software system components dynamically adapting to resource changes wi...

One unfortunate fact of modern life is that functional new software becomes non-functional old software with depressing regularity. For most people, this means predictable episodes of frustration, but for the US military, it's a more serious problem. DARPA's new Building Resource Adaptive Software Systems (BRASS) project aims to take a major shot at avoiding this obsolescence by developing software systems that can still operate properly a hundred years from now.  Read More

X-ray rendering of the WIAMan

For something commonly called a "dummy," the mannequins used in crash tests are surprisingly sophisticated and so specialized that they're not much use out of automotive safety labs. When the US Army went looking for a dummy of its own, it had to go back to square one by awarding a contract to California-based Diversified Technical Systems (DTS) to help develop the first instrumented dummy designed for military vehicle blast testing.  Read More
