FEATURES
Fiber Optics Revolutionizes Neuroscience An occasionally overlooked technology leads to major advances in the field Fiber optics might just be the Rodney Dangerfield of the photonics world: Despite being a workhorse technology that has...
Optical Microscopy Quantifies Live Cells Without Labels With increasing frequency, noninvasive, label-free microscopy methods are capturing subcellular details in live cells and tissues at ever-smaller resolutions. Understanding the complex behavior...
Flexibility Improves Photoacoustic Microscopy Switching from optical resolution to acoustic resolution allows scientists to extract more information from samples. Optical imaging offers the prospect of visualizing anatomical structures and...
Tell-Tale Color Changes: Camera Can Find Age of a Bruise Changes in bruise color allow doctors to draw conclusions about when an injury occurred. To determine physical abuse of a child, several warning signs must be considered: Is the child scared?...
EDITORIAL
Light Brings New Tools to Old Science Neuroscience has a very long history, one that by some measures stretches back to thousands of years B.C. Certainly, the need to understand how our brains work, why things sometimes go wrong and, ultimately, how we can fix what is broken makes it a compelling subject. Some 32,000 neuroscientists are expected to gather this month in New Orleans for the 42nd annual meeting of the Society for...

DNA-based nanoantenna captures, emits light A bio-inspired light nanoantenna comprising two gold nanoparticles, short DNA strands and a tiny fluorescent molecule that can capture and emit light could pave the way to the development of highly efficient LEDs and ultracompact solar cells and could even find use in quantum cryptography. Light is a wave, so it should be possible to develop optical antennas that can amplify light signals in the...
Metamaterial focuses sound waves like a camera lens A computationally tested metamaterial that can manipulate a variety of acoustic waves with one simple device holds promise for various acoustic applications, including medical ultrasound, higher...
Optical microscope breaks Abbe’s limit Combining electronic excitation and optical detection has allowed an optical microscope to break Abbe’s diffraction limit. The new nanoscale imaging method could lead to enhanced biosensors by...
Cancer-fighting laser born at university space institute A new technique harnesses the power of femtosecond lasers to seek, acutely map and noninvasively destroy cancerous tumors, and it could especially benefit brain cancer patients. Developed by...
New approach strengthens negative refraction An “extraordinarily strong” negative refractive index as large as -700 – more than 100 times larger than most previously reported – has been achieved in metamaterials using a...
Diagnosis is in the eyes, thanks to color-coded markers New fluorescent probes that change color when they encounter brain disease markers found in the eye could offer a simpler way to identify neurodegenerative disease and distinguish between closely...
Glowing molecules turn on, off to visualize cell activity Using UV light to switch fluorescent molecules on and off in aqueous environments could help scientists develop better fluorescent probes for biomedical research. The molecules first must be...
RAPIDSCAN
Guidelines needed to advance diagnostic accuracy Tiny mechanical microscopes – those that can see inside single living cells – increasingly are being used to diagnose illness in hard-to-reach areas of the body, but specialists say that improved, standardized guidelines are needed to advance diagnostic accuracy. The little probes often are threaded into the narrow bile duct that connects the liver to the small intestine to...

Lidar reveals elephant impact Scientists and conservation managers have long suspected that elephants browsing for food are the main culprits behind toppled trees in the South African savannas – and airborne lidar and 3-D mapping have helped prove this. Widespread tree loss is a concern to wildlife managers because it is known to have a negative effect on the habitat for many other species. To gain a better...
