Daily numbers of new cases are finally starting to wane, and hospitalizations are down slightly. But health care systems are still overburdened and another resurgence remains a threat.
An antigen test could be quick, and much simpler and cheaper than the PCR tests now used to spot people infected with the novel coronavirus. But some scientists worry about an antigen test’s accuracy.
The Centers for Disease Control and Prevention is urging Americans to start to prepare for the possibility of more aggressive measures to stop the spread of the new coronavirus in the United States.
Victoria Gray, 34, of Forest, Miss., has sickle cell disease. She is the first patient ever to be publicly identified as being involved in a study testing the use of CRISPR for a genetic disease.
This could be a crucial year for the powerful gene-editing technique CRISPR as researchers start testing it in patients to treat diseases such as cancer, blindness and sickle cell disease.
Researchers think genetically engineered versions of microbes that can live in humans could help treat some rare genetic disorders and perhaps help with Type 1 diabetes, cirrhosis and cancer.
The insects were created, using CRISPR, to carry a powerful “gene drive.” The mosquitoes could provide a potent weapon against malaria, but they raise fears about unpredictable environmental effects.
Despite outrage over gene editing in China that affected the birth of twins, research is underway in the U.S. to assess the safety and effectiveness of CRISPR tools to edit genes in human embryos.
U.S. Surgeon General Jerome Adams issued a forceful advisory about vaping by U.S. teenagers, saying electronic cigarette use among young people has reached levels that require urgent action.
In its latest effort to curb smoking by young people, the FDA wants to outlaw menthol cigarettes. The agency would also restrict sales of flavored e-cigarettes to reduce youth addiction to nicotine.
Scientists demonstrate that a “gene drive” can rapidly spread a genetic mutation through a species, perhaps providing a potent new weapon against malaria. But there are plenty of skeptics.
The childhood obesity epidemic rages on in the United States, with a big surge among the youngest kids, according to the latest government data.
The flu season started early this year, and is already widespread throughout the country and intense in dozens of states. But it’s not too late to get that flu shot, officials say.
The opioid epidemic caused U.S. life expectancy to fall for the second year in a row, marking the first time that’s happened since the early 1960s. Death rates also continued to rise.
