Injectable Tissue Patch to Fix Broken Hearts

Scientists at the University of Toronto have developed a bandage-like patch that can be delivered into the heart through a needle, in combination with stem cells allowing for minimally invasive cardiac tissue repair, currently an impossible task. After a massive heart attack, myocardial tissue damage can significantly reduce the cardiac output. One (Read more...)

New Probe to Safely Measure pH Inside Living Cells

An unusually acidic environment around living cells may be an indicator that processes associated with disease are taking place in the vicinity. Of course there’s a myriad of other biological variables related to the cellular pH. To measure the cellular pH levels, fluorescent dyes exist that glow when illuminated by a specific wavelength of l (Read more...)

Smartphone-Powered Diagnostic Spectrum Analyzer Shrinks a Hospital Lab Into Portable Device

Bioengineers at the University of Illinois at Urbana-Champaign have turned a smartphone into a portable diagnostic laboratory capable of performing a range of spectrum analyses that is currently done using large and expensive stationary machines. The investigators built a smartphone attachment that utilizes the smartphone’s camera to analyze (Read more...)

Tissue Paper Made of Various Organs for Use in Wound Healing, Regenerative Medicine, Hormone Production

If you thought sheepskin paper, also known as vellum, is gross, get ready for “tissue paper” from Northwestern University. The material, made from organs mixed with a polymer in a multi-step process, may have a number of uses that are obvious, such as wound repair, and others that will have to be discovered. The tissue paper i (Read more...)

New Method Visualizes Individual Neural Pathways Using Light

The brain’s functional network is both highly complex and hard to peer into, making it difficult to understand how some neurons are related to others and what their interconnectivity is like. Researchers at the Max Planck Institute of Neurobiology in Martinsried, Germany have now developed a way to visualize the electrical activity that  (Read more...)

New Way to Grow Liver Tissue to Repair Damaged Organ

Here’s an interesting new technology that might ameliorate symptoms in patients with liver failure, improve liver function, and decrease demand for liver transplants. Researchers at MIT, Rockefeller University, and Boston University have created a new way of building hepatic tissue that can be used to replace diseased parts of livers. The inv (Read more...)

Baker’s Yeast Now Used for Drug Discovery

Scientists at the University of Toronto and the RIKEN Center in Japan have developed a new approach to help with drug discovery. Rather than requiring human cells, the technique is based on baker’s yeast, which is well-understood at a molecular level. Discovering how drugs work in the body can be very complex. Similarly, it can […]

Expansion Microscopy Swells Samples for Better Imaging

When trying to use light and conventional optics to image a biological sample at great detail, one eventually encounters the fact that objects smaller than the light’s wavelength cannot be resolved. While technological tricks have been developed to overcome this limitation in some ways, a team of researchers from MIT and Harvard have ins (Read more...)

New Imaging Technique Provides Molecular Orientation in Samples to Help Study Neuro Diseases

A team of French scientists has developed a high speed imaging technique that provides them an unprecedented view of the chemical nature of biological samples. Not only does it provide an analysis of the chemical content, it also provides information about the orientation of the molecules detected. The newly available perspective of the molecular d (Read more...)

Researchers Work to Grow Capillaries Inside 3D Printed Molds

Researchers at Rice University and Baylor College of Medicine have overcome an important challenge to using endothelial cells sourced from induced pluripotent stem cells to generate bioengineered blood vessels. Specifically, the investigators were able to watch and guide the formation of tiny blood vessels within specially built molds that promote (Read more...)
