A new study published in the International Journal of Cancer draws some very interesting connection between people’s time for dinner and their risk (风险) of developing certain types of cancers, including breast and prostate (前列腺) cancer, which are two of the largest killers of men and women.

“Modern life often means mistimed sleeping and eating that are connected with poor health effects in experimental studies,” the researchers explain. The research mainly focuses on how long before bedtime a person eats their last meal of the day. People who eat before 9 p. m or eat at least n couple of hours before hitting the sack have lower risks of developing cancers. The scientists find that these people enjoy a 20% drop in cancer risk when compared to those who eat dinner after 10 p.m. or eat right before climbing into bed.

The researchers followed the habits of thousands of people and tracked their nighttime eating habits and whether or not they developed cancer over the long term. The numbers seem to point towards early dinners being a very beneficial thing if you’re hoping to avoid some of the more common types of cancer, but the scientists still don’t know exactly why that’s true. At the moment they believe circadian rhythm (生物钟) is playing a role, though they can’t say exactly how.

The balloons would act like telecommunications satellites, providing Internet service to the rural areas. The huge objects would ride air currents (气流) to either stay in place or move to another position high in the skies. At first, the idea was to have a large number of balloons circling the planet. One balloon would move away from an area while another arrived to ensure service in the affected areas. But the company said it has found a way to make balloons float over one area for a long period. In a report published online, the company said its software “can now send small teams of balloons over a specific area where people need Internet access.”

The company said some of the balloons stayed in the same area for as long as three months. The company also said the discovery should speed up the project and reduce costs: “We’ll reduce the number of balloons we need and get greater value out of each one, they said. But Project Loon workers must still find ways to increase the life of the balloons. A British Broadeasting Corporation report said the longest service for a single balloon was 190 days.

Google has also explored the idea of providing Internet service to rural areas using solar—powered drone aircraft (太阳能无人机). However, it gave up that project because of technological difficulties and high costs.
