Biomeme’s Portable PCR System Expands Research Possibilities

Polymerase chain reaction (PCR) is one of the most widely used techniques in biological research and testing, allowing researchers to amplify and identify even small quantities of DNA or RNA. It serves a wide variety of uses, from genetic testing to infectious disease identification to forensics. Thermal cyclers, the machines that run PCR, are a [& (Read more...)

Cryogenic 3D Printing to Make Replica Brain and Lung Tissues

Printing biological tissues, a necessary precursor to creating replacement organs, is not easy, but constructing extremely soft and fragile tissues that resemble the brain and lungs is even more difficult. Researchers at Imperial College London and Kings College London are now using extremely cold temperatures in combination with 3D printing to cre (Read more...)

Draper’s Microfluidic Artificial Kidney Reproduces Real Thing at Cellular and Tissue Levels

Kidney injuries from exposure to too many drugs are common among certain groups of patients, particularly those spending time in the ICU. Kidney injuries can also happen during drug testing, wounding subjects while eliminating candidate drugs far along their development pipeline. Engineers at Draper have now developed a so-called kidney-on-a-chip, (Read more...)

DiffuserCam: Lensless 3D Imaging without Scanning

Three dimensional images can now be created from a single two dimensional image using a new computational imaging technique developed by a research team at the University of California, Berkeley. A hallmark of the new approach is that it does not require a complex, expensive hardware setup, but instead relies on a compact, inexpensive, lensless [&h (Read more...)

Developed: Brain-on-a-Chip Featuring Multiple Cell Types

Scientists at Lawrence Livermore National Laboratory have developed a way to create “brain-on-a-chip” devices that can be used to study brain function, how various chemical compounds influence it, and what can be done to protect the brain from toxic chemicals, etc. The technology may help lessen the need for laboratory animals, speed up (Read more...)

TeloYears Genetic Test Kit: Product Review

A few months ago, Medgadget spoke with Jason Shelton, CEO of Telomere Diagnostics (TDx) about the new company’s TeloYears genetic test. Compared to other genetic tests, TeloYears assesses an individual’s telomeres, a biomarker that changes with age. TDx’s goal is to provide consumers a new way to quantify their aging progress thro (Read more...)

Plasmonic Biosensor to Detect Exosomes with Naked Eye

Exosomes are vesicles that are released by the body’s cells that end up in our blood, urine, and other bodily fluids. The importance and roles they play within our bodies still has to be elucidated, but there’s already a lot of signs that exosomes are biomarkers of disease and indicators of various cellular processes. Studying [… (Read more...)

Cytotwister, A Unique 3D Stem Cell Bioreactor: Interview with Dr. Hsin-Hsin Shen of Industrial Technology Research Institute

Stem cells are up-and-coming therapies, and a major engineering problem has been scaling up the cell manufacturing to create enough cells for different therapeutic applications. Cytotwister, from the Industrial Technology Research Institute (ITRI) in Taiwan, makes a step towards solving that with a unique 3D stem cell bioreactor system that address (Read more...)

Scientists Create Living 3D Printer Ink Made of Live Bacteria

Researchers at ETH Zurich in Switzerland have reported in journal Science Advances on a way of 3D printing materials infused with live bacteria. The development may lead to devices such as implantable blood filters and bacterial factories that produce biomolecules for drugs and other therapies. A myriad of other applications may find use from this (Read more...)

Carefully Controlled Light Pulses Can Trigger Neurons to Fire

Researchers at the University of Illinois have developed a technique of using a flurry of very short light pulses of different wavelengths to control how mouse neurons fire. Eventually, the technique might be useful for influencing cells in the body that respond to light, such as those in the retina, to treat light-sensitive circadian or […]

Genome Editing Primes T-Cells to Attack Cancer

Scientists at Cardiff University in the UK have found a way to enhance the cancer-destroying ability of T-cells through DNA editing. The research team used CRISPR genome editing technique to remove the receptors naturally present on T-cells, and instead replace them with receptors that would recognize specific cancers cells, causing the T-cells to (Read more...)
