An algorithm to monitor the joints of patients with arthritis, which could change the way that the severity of the condition is assessed, has been developed by a team of engineers, physicians and radiologists led by the University of Cambridge. The technique, which detects tiny changes in arthritic joints, could enable greater understanding of how…
3D Imaging and Computer Modeling Capture Breast Duct Development
Working with hundreds of time-lapse videos of mouse tissue, a team of biologists joined up with civil engineers to create what is believed to be the first 3D computer model to show precisely how the tiny tubes that funnel milk through the breasts of mammals form. A report on the model was published April 9 in Developmental Cell.…

New Hyperlens Can Capture Images of Living Cells
New hyperlenses are giving scientists the ability to capture images of living cells in great detail. A team from Vanderbilt University has created a new hyperlens that can resolve objects much smaller than the wavelength of light using hexagonal boron nitride (hBN)—a natural crystal with hyperlensing properties. Previously, the best resolution using hBN was an…
Molecular Beacon Signals Low Oxygen With Ultrasound
Areas of hypoxia, or low oxygen in tissue, are hallmarks of fast-growing cancers and of blockages or narrowing in blood vessels, such as stroke or peripheral artery disease. University of Illinois researchers have developed a way to find hypoxic spots noninvasively in real time. The researchers developed an oxygen-sensitive molecular beacon that emits ultrasound signals…
Seeing Through Walls of Unknown Materials
Researchers at Duke University have devised a way to see through walls using a narrow band of microwave frequencies without any advance knowledge of what the walls are made out of. Besides having obvious applications in the realm of security, the approach could lead to inexpensive devices to help construction workers easily locate conduits, pipes…
Compact Hyperspectral Imaging at Low Cost
With hyperspectral imaging, photographers can obtain super fine detailed images, capturing the spectrum for each pixel in an image of a scene.
