Physicians urge hospitals to become ‘artificial intelligence ready’

A group of doctors and data scientists is calling on hospitals to create clinical departments devoted to artificial intelligence (AI) to harness the power of the technology to transform patient care. While there have been many predictions of AI’s potential to benefit healthcare delivery — from helping doctors perform surgery to catching cancer earlier —…

A never-before-seen cell state may explain cancer’s ability to resist drugs

Cancer’s knack for developing resistance to chemotherapy has long been a major obstacle to achieving lasting remissions or cures. While tumors may shrink soon after chemotherapy, many times they eventually grow back. Scientists once thought that unique genetic mutations in tumors underlay this drug resistance. But more and more, they are casting their eyes on…

Scientists chart SARS-CoV-2 origin and transmission in Brazil, harboring one of fastest growing COVID-19 epidemics in the world

A team of Brazilian and European scientists has determined the transmission rates and out-of-country origins of predominant SARS-CoV-2 strains currently circulating in Brazil, which harbors one of the fastest growing COVID-19 epidemics in the world. Although the researchers show that non-pharmaceutical interventions initially reduced viral transmission, the continued increases in both cases and deaths in…

New CRISPR C-to-G DNA base editor expands the landscape of precision genome editing

BOSTON — New genome-editing technologies developed by researchers in J. Keith Joung’s laboratory at the Massachusetts General Hospital (MGH) have the potential to help understand disease-associated genetic mutations that are based on C-to-G (cytosine to guanine) single base changes. The new base editors are also designed to minimize unintended («off-target») mutations that could potentially cause…

Covid-19 Patients No Longer Need Tests to End Isolation

Most Americans recovering from Covid-19 can come out of isolation without further testing to show they no longer carry the coronavirus, federal health officials said on Wednesday. Instead, patients may be judged to have recovered if 10 days have passed since they first felt ill; they no longer have any symptoms, such as shortness of…
