3 . Eggs make for a delicious meal, and for the past few years, we’ve been able to enjoy them guilt-free. Now, they are declared as “bad egg” again.
Researchers from Northwestern University collected data from six previous studies that tracked the health of 29, 615 adults for about 18 years on average. After gathering results from the various studies, they concluded that 300 milligrams of cholesterol (胆固醇) per day slightly raised a person’s risk of heart disease. One egg contains about 186 milligrams of cholesterol.
“These participants weren’t given periodic questionnaires, they were given one questionnaire,” says Lauren Slayton, a nutritionist. “That’s like drawing conclusions about someone’s fashion sense by what they wore 20 years ago.” No one followed up to see if the diet reports were accurate or to find out whether people changed their diet.
Frank Hu, a professor of nutrition at the Harvard T. H. Chan School of Public Health, told NPR: “So much data have already been published on this topic, which generally show that low-to-moderate egg consumption (no more than one egg per day) is not associated with increased risk of heart attack.” Plus, there are also many other risk factors that contribute to heart disease.
Before you quit your breakfast favorite, you should know that this research is far from the last word on eggs. In other words, don’t feel like you have to drop eggs from your diet based on one study. If you’re concerned about your cholesterol, discuss your diet with your doctor—and consider your exercise routine and other health factors, too. If your heart risk is rising, you may want to check out the best—and worst—diets for your heart.

8 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放)more than doubling during the 1992 to 2007 window.
So what's the solution(解决方案)? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
