New Efficient Method for Sequencing Epigenetic Modifications

Researchers at the University of Pennsylvania’s School of Medicine have developed a new method for sequencing chemical groups attached to the surface of DNA. These chemical groups are modifications of the DNA bases that convey important information relating to the patterns of gene expression. These modifications have been studied for the past (Read more...)

New Fiber Optic Sensor for In Vivo Photoacoustic Imaging

Researchers at Jinan University in China have tinkered with the design of optical fibers to create a novel new type of sensor for photoacoustic imaging. Because the technology uses flexible fibers, it may have applications for implantable, wearable, and diagnostic medical devices. Photoacoustics involves using laser light to create ultrasound waves (Read more...)

Microfluidic Device Corrals Viable Sperm for IVF

Researchers at Cornell University have developed a microfluidic device to rapidly isolate the strongest and fastest sperm from a sperm sample. The technique should help technicians during the IVF process, as the current method of isolating the most viable sperm is painstaking and can take hours for the manual effort to pay off. During IVF, [&hellip (Read more...)

DNA Empowerment for Lifestyle Changes: Interview with Wellness by Science CEO, Harry Blustein III

As genetic screening technologies continue being developed and offered at ever cheaper prices, members of the general public are growing increasingly curious about what lies hidden in their DNA. While many have elected to sample their genome out of pure curiosity and to get better insight into their family history, the resultant data could often [& (Read more...)

New Device for Studying Bacterial Biofilm Formation

Biofilms are large groups of bacterial cells that stick together and protect each other like a Roman legion. Drugs and other therapies can poke at the exterior of a biofilm, but killing the mass can be extremely challenging. Researchers at the Okinawa Institute of Science and Technology in Japan decided to look more closely at the […]

Automation of Patch Clamp Technique to Speed Brain Studies

The patch clamp technique, for which the 1991 Nobel Prize in Physiology or Medicine was awarded, is widely used to study the electrical activity of individual cells. It is particularly useful in neuroscience because electricity is the language through which neurons communicate. But it is slow and tedious since it requires a trained specialist to [& (Read more...)

New Device for Testing Immunotherapies on Tumor Fragments

Immuno-oncology, a rapidly developing field that harnesses the body’s immune system to attack cancers, lacks effective methods of testing potential therapies. In addition to animal studies, tiny bits of tumors are placed, along with chemical compounds being tested, within multiwell plates and watched over using a number of techniques. While t (Read more...)

Custom 3D-Printed Microfluidics for Cell-Based Health Research

Researchers at NYU Abu Dhabi (yes, there is such a thing) have developed a method to 3D print functional and inexpensive microfluidic probes for cancer research. The technique could make microfluidics more accessible, allowing researchers to easily design and produce their own devices, and conduct cell-based healthcare research, such as studying ca (Read more...)

Molecular Sensor to Detect if Cancer Drug is Working

Being able to monitor the chemical content of cancer cells may help scientists develop new anti-cancer medications. Additionally, it may also lead to personalized drug therapies for cancer patients that all too often end up trying multiple medications before finding one that works. Chemists at MIT have come up with just such a tool for […]
