How to map brain connections using DNA barcodes

A new method developed at Cold Spring Harbor Laboratory (CSHL) uses DNA sequencing to efficiently map long-range connections between different regions of the brain. The approach dramatically reduces the cost of mapping brain-wide connections compared to traditional microscopy-based methods. Neuroscientists need anatomical maps to understand how information flows from one region of the brain to another. “Charting the cellular connections […]

Old drugs might treat COVID-19—so we’re using pieces of coronavirus to find out

Why don’t we have drugs to treat COVID-19 and how long will it take to develop them? SARS-CoV-2—the coronavirus that causes the disease COVID-19—is completely new and attacks cells in a novel way. Every virus is different and so are the drugs used to treat them. That’s why there wasn’t a drug ready to tackle the new coronavirus that only […]

Using ‘organs-on-a-chip’ to model complicated diseases

MIT biological engineers have created a multitissue model that lets them study the relationships between different organs and the immune system, on a specialized microfluidic platform seeded with human cells. Using this type of model, sometimes called “organs-on-a-chip” or “physiome-on-a-chip,” the research team was able to explore the role of circulating immune cells in ulcerative colitis and other inflammatory diseases.

Using technology during mealtimes may decrease food intake, study finds

Being distracted by technology during mealtimes may decrease the amount of food a person eats, nutrition scientists suggest in a new study. When 119 young adults consumed a meal while playing a simple computer game for 15 minutes, they ate significantly less than when they ate the same meal without distractions, said lead author Carli A. Liguori. Liguori conducted the […]

Exploring the deep tissues using photoacoustic imaging

Photoacoustic imaging has gained global attention for capturing images without causing pain or using ionizing radiation. Recently, many researchers have heavily studied observing deep tissues to apply photoacoustic imaging to clinical diagnosis and practices. Prof. Chulhong Kim of Creative IT Engineering from POSTECH and his student, Byullee Park conducted joint research with Prof. Hyungwoo Kim and Kyung Min Lee of […]

Prostate cancer can now be diagnosed better using artificial intelligence

Researchers at Radboud university medical center have developed a ‘deep learning’ system that is better than most pathologists at determining the aggressiveness of prostate cancer. The AI system, which uses tissue samples to arrive at its diagnosis, taught itself to identify prostate cancer based on data from over 1200 patients. The Radboud team is now working with researchers from the […]

Using gene therapy to treat chronic traumatic encephalopathy

A new study shows the feasibility of using gene therapy to treat the progressive neurodegenerative disorder chronic traumatic encephalopathy (CTE). The study, which demonstrated the effectiveness of direct delivery of gene therapy into the brain of a mouse model of CTE, is published in Human Gene Therapy. Ronald Crystal and colleagues from Weill Cornell Medical College, New York, NY, coauthored […]
