FEATURES
Femtosecond Lasers Enable Bladeless Eye Surgery In the past few years, femtosecond lasers have become the “bladeless scalpel” of choice for ophthalmic surgeons. By nature, femtosecond lasers produce extremely brief, high-energy light...
Not Your Father’s Microscope Researchers have devoted increasing effort to developing microscopes that can be used in the field for global health applications. Some have started with the conventional microscope design, condensed...
Biomedical Applications Revealed for Terahertz Spectroscopy Beyond the infrared, but just before you arrive at the microwaves, awaits an emergent area of opportunity for biomedical research: the terahertz region. Spanning from 0.3 to 3 THz (equivalent to 100...
OCT Branches Out For optical coherence tomography, it’s time to branch out. Improvements in imaging, the use of a wider array of wavelengths, and advances in contrast agents promise to make OCT a tool that can...
EDITORIAL
Of bees, children and the cool-ness of science “Real science has the potential to not only amaze, but also transform the way one thinks of the world and oneself.” So starts a wonderful study on the vision of bumblebees published recently in the journal Biology Letters. But what on the surface is a paper about bees learning to solve puzzles is at heart a case for the importance of engaging children in science. It continues,...

Imaging immune response in breathing lung As with toddlers, tissues that are constantly in motion can be difficult to capture in still images without at least a little blurring. But researchers have developed a method of stabilization for living lung tissue that allows more precise imaging without disrupting the organ’s normal function. Neutrophils (green) are visualized moving through alveolar capillaries marked with Texas...
Studying plants’ sensitivity to light A new discovery about the interaction between plant hormones and light signals could have implications for food crop production. Until very recently, it was thought that light signals switch certain...
Snail defends itself with light The clusterwink snail has been found to use its shell to scatter its bright-green bioluminescence in all directions, possibly as a means of making itself look bigger to ward off predators. ...
Tracking molecules in live tissue at video rate New advances in microscopy using stimulated Raman scattering (SRS) have allowed researchers at Harvard University to capture blood cells being squeezed through capillaries. Previously, SRS microscopy...
Ozone makes nanotubes shine brighter A breakthrough in carbon nanotubes could expand their biological and material applications, allowing them to be tracked in single cells or used in novel lasers and more. By adding minute amounts...
Finding cancer cells fast Waiting for biopsy results is nerve-racking, but a new tissue-imaging technique could cut down that stressful period to mere minutes. A novel microscopy technique developed at the University of...
Checking glycemic index with NIR light Reliable and noninvasive ways to check blood sugar have proved elusive, but a new effort by scientists at the National Food Research Institute could bring a near-infrared spectroscopy-based approach...
“Shotgun” method exposes cells’ sugar coatings Almost every type of cell in the human body is covered in sugar molecules called glycans, but scientists have found that analyzing and understanding these molecules have proved difficult because of...
UV light helps skin cancer cells thrive By activating the enzyme protein kinase D, ultraviolet light helps nonmelanoma skin cancer cells survive and proliferate, researchers have found. The new research demonstrates that the effects...
World’s fastest camera takes on biosensing A new ultrafast camera will have applications in biological processes as well as automotive collisions and astronomical observations. The Megaframe Imager can record images at 1 million fps, far...
Blue light and platinum fight cancer Blue light could become a big cancer killer by activating what could be a powerful platinum-based treatment. A research team led by the University of Warwick, with researchers at Ninewells...

Squirming Under the Glare of Directed Light There you are, a simple worm simply slithering along, when a light from above strikes part of your body. Suddenly, you start wriggling in a new direction – not one of your choosing. What has happened to your free will? In the lab of Hang Lu, an associate professor in the Georgia Institute of Technology School of Chemical & Biomolecular Engineering in Atlanta, members of the worm species...
