Coronaviruses are types of viruses that typically affect the respiratory tracts of birds and mammals, including humans. Doctors associate them with the common cold, bronchitis, pneumonia, and severe acute respiratory syndrome (SARS), and they can also affect the gut. These viruses are typically responsible for common colds more than serious diseases. However, coronaviruses are also...Read More

The SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) virus, which hit China with the disease now named COVID-19 in December 2019 and has since spread to over 70 countries, has caused over 90,000 cases, and 3,117 fatalities, with 95% or more of both being in China. COVID-19 is being studied intensively, on an unprecedented scale....Read More

New research zooms in on several antiviral drugs that scientists could repurpose to treat infections with the novel coronavirus. These drugs include teicoplanin, oritavancin, dalbavancin, monensin, and emetine. According to the latest report from the World Health Organization (WHO), there are currently 81,109 confirmed cases of COVID-19 — a condition that develops due to infection with the...Read More

Using a machine-learning algorithm, MIT researchers have identified a powerful new antibiotic compound. In laboratory tests, the drug killed many of the world’s most problematic disease-causing bacteria, including some strains that are resistant to all known antibiotics. It also cleared infections in two different mouse models. The computer model, which can screen more than a...Read More

3D printing of artificial scaffolds intended to replace injured tissues has become a ballyhooed technology that’s yet to prove itself in clinical practice. One issue that complicates things is that the scaffolds have to match the volume that they’ll be replacing, in both shape and the direction in which cells will have to grow. To...Read More

A variety of congenital cardiac abnormalities require the placement of prosthetic heart valves in very young children. As the hearts grow, the valves have to be replaced through repeated surgeries. A team of researchers from Harvard and Boston Children’s Hospital have now developed an artificial valve that can be expanded, via a minimally invasive transcatheter...Read More

When undergoing MRI scanning, many patients have to have the body parts being imaged strapped into rigid radio-frequency (RF) coils. These can be uncomfortable, as they’re not custom-sized for every patient, and since many MRI exams can take a half hour or more to perform, the scanning process can be difficult for many to undergo....Read More
