Microfluidic Device Detects Bacteria in Tiny Samples

Canadian researchers at McGill University and University of Toronto have come up with a new device for rapid detection of small concentrations of pathogenic bacteria within tiny samples. The technology may help to spot diseases early, and so allow clinicians to better treat their patients while slowing down the spread of infection. The device consi (Read more...)

Map’s Connectivity Map Traced by Artificial Neural Networks

Our brains are composed of billions of nerve cells and each of those cells can be connected to thousands of other individual cells, making for an incredibly complex network. While three-dimensional electron microscopy is used to image cells and their connections, typically manual observation and mapping is used to create the connectivity diagr (Read more...)

Bioengineered Bone Grafts for Large Bone Defects

Researchers at the New York Stem Cell Foundation have developed a technique to produce bioengineered bone grafts for large bone defects, which are currently difficult to treat using conventional techniques. To deal with bone defects, clinicians currently use either synthetic materials or bone grafts from the patient or a donor. However, these graft (Read more...)

Method Tracks How Cancer Drugs Spread to Tumor Cells

When it comes to anti-cancer drugs, it’s not only their effectiveness at killing the intended target that we want to know, but also their ability to reach and penetrate the cancer cells. Knowing whether the drug actually enters cancer cells can be as important as whether it’s effective once inside. Now researchers at Francis Crick (Read more...)

Device Detects Mosquitoes Carrying Pathogenic Viruses

Mosquitoes are usually only an unpleasant nuisance, but when they’re carrying diseases we only find out once people start showing up sick at hospitals and clinics. A spinoff from Purdue University is hoping to give public health professionals, and mosquito eradication programs, an early warning system to know where to direct their resources. (Read more...)

Scientists Use Organ on Chip to Grow New Kidney Cells

Scientists at Harvard’s Wyss Institute have come up with a way of growing podocytes, kidney cells that filter out blood, from induced pluripotent stem cells inside a special chamber that replicates the glomerulus of a kidney. These cells, provided an environment similar to their natural one, have shown remarkable identity to their a (Read more...)

Nanolasers to Shine Light on Things Inside Body

At the Lawrence Berkeley National Laboratory, scientists have created microscopic lasers that may end up being used for imaging inside the body, control of biological activity via optogenetics, and performing novel biological studies on living specimens. The lasers, which are about 5 microns in diameter, smaller than red blood cells, turn infrared (Read more...)

New Microscopy Technique Can Image Living Tissues in Real Time

Researchers at the University of Illinois have developed a new microscopy technique that can image living tissue in real time, without the need for chemical stains or dyes. The technique can achieve significant detail, such as allowing researchers to see the movement of vesicles, which are tiny transport packages, between cells. This approach could (Read more...)

Light Beams Guide Growth of Cells and Entire Tissues

European Molecular Biology Laboratory (EMBL), a European intergovernmental research organization, has announced that its scientists have managed to harness the power of optogenetics to guide how cells and tissues grow. They were able to generate different tissue shapes, a capability that may develop into growing tissues for therapeutic applications (Read more...)
