Eucalyptus leaves showing traces of different minerals including gold

Scientists from Australia's Commonwealth Scientific and Industrial Research Organisation have discovered that eucalyptus trees in the Australian outback are drawing up gold particles from deep underground through their root system and depositing the precious metal in their leaves and branches. Rather than being a new source of "gold leaf," the discovery could provide a cheaper, more environmentally friendly way to uncover valuable gold ore deposits.  Read More

Neutrons have a set of unique properties that make them better suited than light, electrons, or x-rays for looking at the physics and chemistry going on inside an object. Scientists working out of MIT's Nuclear Reactor Laboratory have now invented and built a high-resolution neutron microscope, a feat that required developing new approaches to neutron optics.  Read More

A team of engineers at UCLA has created a 3D-printed attachment that enables smartphone cameras to image particles as small as 90 nanometers. This marks the first time that single nanoparticles and viruses have been detected using a cellphone-based imaging system.  Read More

When it comes to capturing visual information in photographs, you typically have two choices – use a wide-angle lens to capture as many parts of a scene as possible, or use a close-up lens to better capture the details of one of those parts. However, with a new camera system developed by engineers at the University of California, San Diego, you can do both at once. What's more, the lens used in this system is just one-tenth the volume of a conventional wide-angle lens.  Read More

Images taken by the 6.5 meter Clay telescope with and without the new adaptive optics syst...

Astronomers have developed a new visible-light adaptive optics (AO) system for the 6.5 meter diameter Magellan-Clay telescope in Chile's Atacama desert. The new AO system replaces the secondary mirror of the telescope with a thin adaptive mirror that can be deformed by its 585 mechanical actuators at a rate of more than 1000 times a second to correct for the image smearing effects of atmospheric turbulence. The result is the sharpest astronomical images ever produced – more than twice as sharp as can be achieved by the Hubble space telescope viewing objects through the vacuum of space.  Read More

The GMT will be completed in 2020 and sport a resolution 10 times greater than the Hubble ...

Slated for completion by 2020, the Giant Magellan Telescope (GMT) will combine seven of the largest and most precisely built telescope mirrors, to offer image resolutions 10 times greater than Hubble at around one third of the cost. The telescope will be used to study the early universe and answer open questions on dark matter, supermassive black holes, and the nature of planets beyond our solar system.  Read More

Plans are underway to provide a digital alternative to traditional autopsy (Photo: Shutter...

By using raw data from Multi Slice Computerized Tomography (MSCT) and processing it through sophisticated software on high performance computer systems, Malaysian entrepreneur Mathavan (Matt) Chandran hopes to largely negate the need to slice open bodies at autopsy. His digital autopsy software exploits the power of existing 2D and 3D imaging and visualization equipment to observe and investigate the human body using high definition imagery.  Read More

Harvard researchers have found a way to create 3D images by juxtaposing two images taken f...

A team at the Harvard School of Engineering and Applied Sciences (SEAS) has come up with a promising new way to create 3D images from a stationary camera or microscope with a single lens. Rather than expensive hardware, the technique uses a mathematical model to generate images with depth and could find use in a wide range of applications, from creating more compelling microscopy imaging to a more immersive experience in movie theaters.  Read More

Using Caltech's system, an ordinary microscope can capture 100 times more information per ...

Thanks to research being conducted at the California Institute of Technology, regular microscopes could soon be capable of much higher-resolution imaging. Instead of making changes to the microscopes’ optics, the Caltech researchers are instead focusing on using a computer program to process and combine images from the devices.  Read More

Fundamental to the Internet of Things is the idea that objects must be uniquely identifiable. RFID chips are perfect for assigning objects a digital fingerprint, at least so far as traditional manufacturing goes. But with the rise of 3D printing, incorporating an RFID chip into your object means interrupting the printing process. Now, scientists have come up with a way to 3D print a unique tag, called an InfraStruct, inside the object as it's being printed, and it's made possible by the slowly emerging field of terahertz imaging.  Read More
