Early observational studies seemed promising. But the gold-standard evidence on hydroxychloroquine is beginning to mount, and it's not looking good.
Forget cars: Ford is now in the "mobility" business. In an exclusive Newsweek interview, company CEO Jim Hackett says autonomous vehicles are the biggest revolution since the Model T.
In the early 1970s, Freeman Dyson wrote an essay comparing space travel to the colonization of the New World and the settlement of the American West. The subject was fanciful, but that didn't keep Dyson, an eminent physicist and writer for the Institute for Advanced Study at Princeton, from making a meticulous effort to quantify and compare the costs of these vastly different ventures.
The last time world leaders talked about halting global warming, in Kyoto in 1997, they lacked a consensus. The U.S. Senate had spurned the talks by a vote of 95–0, eliminating any chance that the United States, then the world's biggest emitter of carbon dioxide, would take a leadership role.
As Europe makes repairs to its shiny new particle accelerator, U.S. rivals prepare to steal the prize.
In what may be remembered as the age of biology, Craig Venter is the field's pre-eminent innovator. He startled the world by making rapid strides towards sequencing the DNA of a human genome at Celera Genomics. (His well-publicized race with Francis Collins, president of the National Human Genome Research Institute, ended in a gentlemen's tie when the two scientists and President Bill Clinton heralded the project's completion in 2001.) Last week, Venter announced that his private institute had...
The best way to attack cancers and other diseases is to be watchful for the earliest signs. That's why medical researchers are excited about the potential for diagnostic techniques involving proteins--workhorse molecules that carry out myriad tasks required to keep the human body functioning.
It's never easy to plumb the reading habits of children, but teachers and parents perennially knock themselves out with worry over any sign of a decline. Among U.S. teenagers, reading skills haven't improved in high schools since 1999, according to the National Assessment of Educational Progress, a standardized test.
News of the devastation caused by aids has been a steady drumbeat for decades now, and it keeps getting louder. The New York-based Council on Foreign Relations recently reported that 39 million people are expected to die of the disease in the next five or 10 years, and warns that some countries may find themselves unable to perform basic functions of governance.
Fusion energy wasn't new back in 1972, when physicist Robert Goldston first arrived at the Princeton Plasma Physics Laboratory as a graduate student. His colleagues were ecstatic over generating one tenth of a watt of electricity for one hundredth of a second--enough to make a light bulb flicker. "We thought that was so amazing," he says, "we held a big party."More than three decades later, the celebrations are still going on, but no bulbs are lit.
