Imaging cells and tissues under the skin

Scientists have many tools at their disposal for looking at preserved tissue under a microscope in incredible detail, or peering into the living body at lower resolution. What they haven't had is a way to do both: create a three-dimensional real-time image of individual cells or even molecules in a living animal.

Enzyme catches a ride to fight infection

Scientists have shown for the first time that an enzyme crucial to keeping our immune system healthy “surfs” along the strands of DNA inside our cells. The researchers used extremely powerful microscopy to watch how the enzyme AID (activation-induced deoxycytidine deaminase) moves around and interacts with other molecules.

First pictures of cells' DNA-copying machinery

The first-ever images of the protein complex that unwinds, splits, and copies double-stranded DNA reveal something rather different from the standard textbook view. The electron microscope images, created by scientists at the U.S. Department of Energy's Brookhaven National Laboratory with partners from Stony Brook University and Rockefeller University, offer new insight into how this molecular…

Panasonic set to launch 4K Ultra HD Micro Camera

Panasonic will launch a 4K Ultra HD micro camera at the forthcoming Compamed tradeshow in Düsseldorf, starting on Monday 16 November. The 4K micro camera (GP-UH532) has 3840x2160 resolution at 60p. It is capable of outputting images at up to 1600 TV lines, for smooth, detailed images and accurate colour reproduction.

Alternative routes to immortality

Every time a cell divides, the ends of chromosomes – the threads of DNA residing in the nucleus – shorten a bit. Once the chromosome ends, called telomeres, become too short, cells normally stop dividing. Scientists from the German Cancer Research Center (DKFZ) have now discovered how cancer cells make use of specific DNA repair enzymes to extend the telomeres. In this way, they escape the…

Triple treatment keeps cancer from coming back

Lung cancer is the leading cause of cancer death worldwide, responsible for some 1.59 million deaths a year. That figure is due, in part, to the fact that the cancer often returns after what, at first, seems to be successful treatment. And the recurring cancer is often resistant to the chemotherapy and other drugs that originally drove it into remission. According to new research by the Weizmann…

Speeding identification of deadly bacteria

A new way of rapidly identifying bacteria, which requires a slight modification to a simple microscope, may change the way doctors approach treatment for patients who develop potentially deadly infections and may also help the food industry screen against contamination with harmful pathogens, according to researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon,…

Biopsy results

Gideon Ho, CEO and co-founder of Singapore-based HistoIndex is confident: ‘After a biopsy a patient waits in a hospital bed, but now, instead of waiting a couple days until doctors know how to treat this patient, we can deliver results while the patient is still in the hospital.’ Report: John Brosky

Molecular diagnostics

Research in the field is booming thanks to newly arriving methods to identify gene sequences. Scientists are interested in a wide range of issues from disease-relevant variations of human genetic information to the detection of viral genetic material that supports therapies. Several highlights of current research were presented this spring at the 9th International Symposium on Molecular…
