Fertility rates picked up slightly in 2021, ending a sustained decline since 2014, the U.S. government said. Rising fertility rates have not changed the overall demographic picture of the United States. Since 2007, the U.S. fertility rate has largely plummeted.

The weather in India and Pakistan this spring has been unusually hot. Unusually large heat waves have followed since March, continuing into May. This presents a difficult problem for rapidly studying the role of climate change in this event, as we can’t yet be sure when it will end. However, two studies have already explored

Self-driving cars — an idea that could improve fuel efficiency, travel time and safety for all cars on the road, even in small numbers — will be tested on roads near Nashville, Tennessee, later this year. Benedetto Piccoli and colleagues at Rutgers University in New Jersey previously used a computer model of a simple circular

Over the past few years, more and more inventions have involved AI. AI helps design drugs, develop vaccines, and discover new materials. Its widespread use poses a challenge to the existing patent system . Because the old patent law assumed the inventor was a human being. If courts and governments decide that inventions created by

Nearly half of sun-like stars are in binary or multiple star systems. How do such galaxies affect the formation of planets ? According to a study published in the journal Nature, planetary systems form around binary stars very differently than around single stars such as the sun. The new findings are based on observations of

The study found that if the time spent watching TV was reduced to less than an hour a day, more than one in 10 coronary heart disease cases could be prevented. Coronary heart disease occurs when fatty substances build up in the coronary arteries, reducing blood flow to the heart muscle and reducing the blood
