Caffeine could protect the heart by helping it make energy, mouse study finds

Health
Coffee can do more than just keep people awake for the day -- studies have shown that moderate amounts of caffeine, like what's in coffee, can actually protect the heart. A new study looked at possible reasons for those beneficial effects, by studying the genes of mice. "We wanted to do this study to show people coffee is not as bad for your heart as people thought for a long time," co-author Dr. Judith Haendeler, medical faculty at the HHU Duesseldorf and IUF-Leibniz Research Institute for Environmental Medicine, told ABC News. But why could coffee-like caffeine levels be helpful for the heart? Building on their previous research that showed that caffeine could help with the repair of cells lining blood vessels, called endothelial cells, researchers at the Heinrich-Heine-University a...

Unique microbe could thrive on Mars, help future manned missions

Science
June 18 (UPI) -- New research suggests certain cyanobacteria could thrive on Mars. The microbes could even be used to provide future space colonies with oxygen. "This might sound like science fiction, but space agencies and private companies around the world are actively trying to turn this aspiration into reality in the not-too-distant future," Elmars Krausz, chemistry professor at Australian National University, said in a news release. "Photosynthesis could theoretically be harnessed with these types of organisms to create air for humans to breathe on Mars." Cyanobacteria are the only photosynthetic prokaryotes capable of producing oxygen. They're the most abundant ground of bacteria on the planet and have colonized Earth since as early as 2.5 billion years ago. Several cyanobacteria h...

Emoji might not be your first line of communication in a disaster... But researchers feel they could make a difference during emergencies like earthquakes, where every second counts.Now, an international group of scientists are lobbying for an earthquake emoji to be added to the Unicode set - the standard group of icons available on digital devices worldwide.But can one emoji really make a difference in a crisis?Emoji-quake"Maybe up to one third of the world's population might be exposed to some [seismological] hazard," explains University of Southampton seismologist Dr Stephen Hicks, a founder of the Emoji-quake campaign. "So we really want to be able to communicate to all of those regions, all of those different languages, and an emoji is an amazing way...

It will take more than moving across an ocean to escape the long arm of the IRS. Americans who hold assets in foreign countries are required to report those accounts to the appropriate federal authorities — or else face penalties as high as $ 100,000 or 50 percent of the account balance. Despite the severe punishment for failure to report, Americans abroad still have a lot to learn about their reporting requirements. Those were the findings of a recent survey by Greenback Expat Tax Services. From late March to May 2018, the company polled more t...
