Fluorescent probe could reveal cancer

Fluorescent probe could reveal cancer
A fluorescent probe developed by Michigan Tech chemist Haiying Liu illuminates the enzyme beta-galactosidase in a cell culture, which could help cancer surgeons. What if you could plaster cancer cells with glowing "Here We Are" signs, so surgeons could be confident that they'd removed every last speck of a tumor? That's what Haiying Liu has in mind for his new fluorescent probe.

Low-cost method produces light-based lab-on-a-chip devices

A fabrication process could make it easier and less expensive to incorporate optical sensing onto lab-on-a-chip devices. These devices integrate laboratory functions onto a plastic or glass "chip" typically no more than a few square centimeters in size, allowing automated testing in the doctor's office or various types of chemical or biological analysis with portable instruments.

Taking pictures of the brain with surgical needle and laser light

Taking pictures of the brain with surgical needle and laser light
  With just an inexpensive micro-thin surgical needle and laser light, University of Utah engineers have discovered a minimally invasive, inexpensive way to take high-resolution pictures of an animal brain, a process that also could lead to a much less invasive method for humans.

Method controls cell biology with light

Method controls cell biology with light
Researchers at the University of Alberta have developed a new method of controlling biology at the cellular level using light. The tool—called a photocleavable protein—breaks into two pieces when exposed to light, allowing scientists to study and manipulate activity inside cells in new and different ways. First, scientists use the photocleavable protein to link cellular proteins to inhibitors, preventing the cellular proteins from performing their usual function. This process is known as caging.

Imaging technology creates 3D bladder reconstruction

Imaging technology creates 3D bladder reconstruction
The way doctors examine the bladder for tumors or stones is like exploring the contours of a cave with a flashlight. Using cameras attached to long, flexible instruments called endoscopes, they find that it’s sometimes difficult to orient the location of masses within the bladder’s blood vessel-lined walls. This could change with a new computer vision technique developed by Stanford researchers that creates 3D bladder reconstructions out of the endoscope’s otherwise fleeting images.

Towards red-light regulated optogenetic tools

Towards red-light regulated optogenetic tools
  The aim of optogenetics is to control genetically modified cells using light. A team of Graz scientists led by Andreas Winkler from the Institute of Biochemistry at TU Graz have set a milestone in the future development of novel red-light regulated optogenetic tools for targeted cell stimulation.

Optical tweezers unveil the secret of muscle power

Optical tweezers unveil the secret of muscle power
Researchers at the Technical University of Munich (TUM) have measured the forces acting between the building blocks titin and α-actinin which stabilise the heart muscle. The human body is a never-ending construction site: Proteins are permanently being decomposed and replaced. But this perpetual reconstruction does not inhibit the body’s functionality.

Optogenetics fine-tuned

Optogenetics fine-tuned
Currently, optogenetics is a blunt-force instrument for manipulating neural activity, which limits its usefulness in the delicate environment of the brain. Researchers have demonstrated that optogenetics can be used as a finely tempered tool to observe and manipulate neural activity. Recent reports have emerged providing the opportunity to balance out excitation and inhibition of neural circuits using optogenetic techniques.

No more searching in vein

No more searching in vein
Now with HD imaging and Df2 technology, Christie Medical can find the best venepuncture site when taking blood and try and avoid those oh so common complications. Instead of the nurses having to fiddle around and try to find a vein in several parts of your arm and body, VeinViewer is an imaging device which uses near-infrared light that is absorbed by the blood and then reflected by surrounding tissue.

Retinal imaging technique gives a closer look at the eye

Retinal imaging technique gives a closer look at the eye
Researchers at the University of Rochester Medical Center have developed a new imaging technique that could revolutionise how eye health and disease are assessed. The group is first to be able to make out individual cells at the back of the eye that are implicated in vision loss in diseases like glaucoma. They hope their new technique could prevent vision loss via earlier diagnosis and treatment for these diseases.
