The U.S. insisted that new international guidelines on combating drug resistance omit any mention of fungicides — a demand that the industry made but that ran counter to science.
The first stages of placental development take place days before the embryo starts to form in human pregnancies. The finding highlights the importance of healthy placental development in pregnancy, and could lead to future improvements in fertility treatments such as IVF, and a better understanding of placental-related diseases in pregnancy.
Scientists have described a new nanodevice that acts almost identically to a brain cell. Furthermore, they have shown that these synthetic brain cells can be joined together to form intricate networks that can then solve problems in a brain-like manner.
Researchers have discovered a novel, second mechanism of action by the antiviral drug remdesivir against SARS-CoV-2. The research team previously demonstrated how remdesivir inhibits the COVID-19 virus’s polymerase or replication machinery in a test tube.
The C.D.C. reported a pattern of young people getting sick over the summer — and then older generations getting the virus days later. The Israeli government will tighten its second national lockdown as new cases soar.
A biking accident left Kirk Williams paralyzed, but he has traveled widely and inspired others to follow in his tire tracks.
An unprecedented effort is under way to rapidly develop Covid-19 vaccines, with pharmaceutical companies, academic researchers, and government agencies aiming to compress into several months a process that typically requires at least several years. This work is supported by extraordinary public and…
More than 200,000 complaints of scams and fraud have been filed so far this year, data from the Federal Trade Commission shows.
A new survey of six U.S. states has found that during the past two months, more people are wearing masks, vaccine uncertainty is on the rise, and many people are overestimating their risk of becoming seriously ill and dying from COVID-19.
Analyzing anonymized patient medical records, researchers discovered that cholesterol-lowering statins reduced risk of severe COVID-19 infection, while lab experiments uncovered a cellular mechanism that helps explain why.
