The famous photo of Buzz Aldrin walking on the surface of the Moon during the Apollo 11 mi...

When the moon-walking Apollo 11 astronauts returned to Earth in 1969, amongst the 47.5 pounds (21.5 kg) of lunar rocks they brought with them were three minerals from Tranquility Base that were thought to be unique to the Moon or lunar and possibly Martian meteorites. They were armalcolite (named after Neil Armstrong, Edwin ‘Buzz' Aldrin and Michael Collins), pyroxferroite and tranquillityite. Both armalcolite and pyroxferrite were later found on Earth, leaving tranquillityite as the last mineral believed to have no terrestrial counterpart. Now tranquillityite has also been struck off the list with its discovery in the remote Pilbara region of Western Australia.  Read More

IBM scientists have created a flexible silicon probe, that could allow for more precise st...

IBM scientists in Zurich have created a proof-of-concept device, that could change the way that human tissue samples are analyzed. Presently, samples must be stained with a biomarker solution in order to detect the presence of a disease. The staining process can be quite involved, however, plus it is subject to error – too much of the solution can cause inaccurate results, for instance. Additionally, it can sometimes be difficult to perform enough tests using the small amount of tissue extracted in most biopsies. The IBM technology, though it still involves staining, is said to offer a potential solution to these shortcomings.  Read More

Researchers claim a newly discovered molecule found in the Earth’s atmosphere holds the potential to help offset global warming by actually cooling the planet. The molecule is a Criegee biradical or Criegee intermediate, which are chemical intermediaries that are powerful oxidizers of pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. They have the ability to naturally clean up the atmosphere by helping break down nitrogen dioxide and sulfur dioxide to form sulfate and nitrate, which ultimately leads to cloud formation that could help cool the planet.  Read More

The particle-free silver ink is here applied to a thin, stretchy plastic film to make a fl...

There’s no doubt that we will soon be seeing a lot more in the way of low-cost electronic circuits that have been printed onto common, flexible materials such as plastic, paper or fabric. One of the key technological innovations making this possible is silver ink, which is used to print these circuits’ conductors. While such ink usually incorporates particles of silver suspended in a carrier liquid, a new type of ink created at the University of Illinois forgoes the particle approach, and is said to offer some distinct advantages as a result.  Read More

A bio-feedback armband called BodyWave is the first of its kind to measure brainwave activity through the body, not the scalp. Instead of an EEG headset recording a user's concentration level, the Bodywave reads brainwaves at the arm by measuring the electric current given off by neurons firing in the brain. Bundled with an interactive software package called Play Attention, it reportedly enables interactive feedback and training towards peak mental performance. Apart from the obvious potential in sport, its ability to train attention and teach stress-control in mobile situations (much less obtrusively than wearing a headset) opens up wider potential. It has already found applications in education, industry and the military as well as in improving the lives of people with disabilities like Attention Deficit Hyperactivity Disorder (ADHD).  Read More

With a superlens microscope, everyday people would be able to see minute details of tiny o...

Some day, you may have a microscope on your smartphone camera that's as powerful as a scanning electron microscope. If you do, it will likely be thanks to research presently being conducted by Durdu Guney, an assistant professor of electrical and computer engineering at Michigan Technological University. He is working on creating a metamaterial-based "superlens" - a long sought-after optically-perfect lens, that could use visible light to image objects as small as 100 nanometers across.  Read More

German scientists have created the world's smallest magnetic data storage unit, which can ...

If you’re impressed with how much data can be stored on your portable hard drive, well ... that’s nothing. Scientists have now created a functioning magnetic data storage unit that measures just 4 by 16 nanometers, uses 12 atoms per bit, and can store an entire byte (8 bits) on as little as 96 atoms – by contrast, a regular hard drive requires half a billion atoms for each byte. It was created by a team of scientists from IBM and the German Center for Free-Electron Laser Science (CFEL), which is a joint venture of the Deutsches Elektronen-Synchrotron DESY research center in Hamburg, the Max-Planck-Society and the University of Hamburg.  Read More

Ion Proton Sequencer by Life Technologies is designed to sequence the entire human genome ...

The mapping of the human genome, announced at the White House back in 2000, had immense impact on biomedical research. It allowed us to gain insights into how biological information is encoded in the genome, helped us understand the biological mechanisms behind cancer and hereditary diseases and enabled us to look much deeper into the history of our own species. These are milestone achievements for humanity as a whole, but they have little or no direct impact on everyday medical treatment. That could be about to change, however, as Life Technologies introduces the Benchtop Ion Proton Sequencer - a machine that may finally deliver the power of genetics into the hands of ordinary doctors.  Read More

Scientists have created a new type of thermal management system, that utilizes jumping dro...

When you have wet skin, you no doubt notice a cooling sensation as it dries. This is because the water droplets are carrying heat away from your skin with them, as they evaporate. Phase-change thermal diodes work the same way – through an evaporation and condensation process, they use liquid to transport heat away from things such as microchips. In most of these diodes, liquid placed on a hot surface evaporates, the vapor then rising onto a cooler surface, where it condenses back into liquid. In a closed-loop cycle, gravity subsequently carries that condensate back down to the hot surface, so it can once again be evaporated. Now, scientists from North Carolina's Duke University have discovered a method of getting condensed water droplets to jump back to the hot surface – and they can do so in any direction, including straight up.  Read More

A new nanosensor developed by Fraunhofer researchers could reduce the number of lab experi...

Animal testing is an area that elicits strong feelings on both sides of the argument for and against the practice. Supporters like the British Royal Society argue that virtually every medical breakthrough of the 20th century involved the use of animals in some way, while opponents say that it is not only cruel, but actually impedes medical progress by using misleading animal models. Whatever side of the argument researchers fall on, most would likely use an alternative to animal testing if it existed. And an alternative that reduces the need for animal testing is just what Fraunhofer researchers hope their new sensor nanoparticles will be.  Read More
