European researchers have come up with a method to 3D print in metal using tiny drops of copper and gold with the help of a laser. The ability to print more structures that better conduct heat and electricity could lead to entirely new devices and components being created.
Australia is wasting billions of dollars of potential value by shipping its world-beating titanium reserves out of the country as raw ore. That's why CSIRO's Lab 22 is making millions of dollars' worth of 3D printing facilities available to Australian businesses in an effort to kick-start a local additive manufacturing revolution that could add billions of dollars' worth of value to the country's raw titanium exports.
PlanetiQ has begun testing its new Pyxis weather instrument. Pyxis tracks GPS signals traveling through the atmosphere and makes measurements based on their behavior. PlanetiQ says it can "dramatically improve weather forecasting, climate monitoring and space weather prediction."
Having previously used Wi-Fi signals to look through walls, a team of researchers in professor Yasamin Mostofi's lab at the University of California, Santa Barbara, has now turned the wireless signals to the task of counting the number of people walking in a particular area – even if they aren't carrying any Wi-Fi-enabled devices.
A new study by MIT has revealed that the quantities of nitrous oxide (N2O), otherwise known as laughing gas, being released by the world's oceans has been dramatically underestimated. Heightened levels of N2O have the potential to seriously influence the health of our planet's ozone layer, as the gas is around 300 times more potent than the more prevalent menace of carbon dioxide emissions.
While there are already plenty of apps that help birdwatchers identify
birds, most of them work by searching a database based on descriptions.
Cornell University and the Visipedia research project's Merlin Bird
Photo ID program, however, goes further – it utilizes computer vision
tech to identify birds pictured in user-supplied photos.
Researchers from Vanderbilt University in Nashville, Tennessee have created the world's smallest continuous spirals. Made from gold, the spirals exhibit a set of very specific optical properties that would be difficult to fake, making them ideal for use in identity cards or other items where authenticity is paramount.
Identifying fraudulent paintings based on electrochemical data, highlighting cancerous cells in a sea of healthy ones, and identifying different strains of bacteria in samples of food are all examples of surface-enhanced Raman spectroscopy (SERS), a sensor system that has only become more in-demand as our desire for precise, instantaneous information has increased. However, the technology has largely failed commercialization because the chips used are difficult and expensive to create, have limited uses for a particular known substance, and are consumed upon use. Researchers led by a team from the University of Buffalo (UB) aim to change nanoscale sensors with an almost-universal substrate that's also low-cost, opening up more opportunities for powerful analysis of our environment.
Currently, recipients of arm or leg transplants need to take
immunosuppressive drugs for the rest of their lives, in order to keep
the donated parts from being rejected. If we could grow our own
replacement limbs, however, that wouldn't be necessary. And while we do
already possess the progenitor cells needed to grow such parts, what's
been lacking is a method of assembling them into the form of the desired
limb. Now, however, scientists have created a shortcut of sorts –
they've stripped the cells from one rat's forelimb and replaced them
with live cells from another rat, creating a functioning limb that the
second rat's immune system won't reject.
