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.

Project aiming to advance medical imaging

 Project aiming to advance medical imaging
As medical imaging is becoming increasingly important, an EU-China network has been established in order to overcome the challenge of storing and retrieving these images. Searching archives of digital images using text descriptors is like trying to find a needle in a haystack. This phenomenon also applies to medical imaging.

Tool uses UV light to control inflammation

Tool uses UV light to control inflammation
Black light does more than make posters glow. Cornell researchers have developed a chemical tool to control inflammation that is activated by ultraviolet (UV) light. The method will allow scientists to study inflammation and the immune system, and may one day prove effective as a targeted therapy for inflammatory diseases, while minimising side effects to healthy tissues.

3D imaging technique maps migration of DNA-carrying material

3D imaging technique maps migration of DNA-carrying material
Scientists have mapped the reorganisation of genetic material that takes place when a stem cell matures into a nerve cell. Detailed 3D visualisations show an unexpected connectivity in the genetic material in a cell's nucleus, and provide a new understanding of a cell's evolving architecture. These unique 3D reconstructions of mouse olfactory cells, which govern the sense of smell, were obtained using X-ray imaging tools at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).
