'Cyborg' bacteria deliver green fuel source from sunlight

Science
Scientists have created bacteria covered in tiny semiconductors that generate a potential fuel source from sunlight, carbon dioxide and water.The so-called "cyborg" bugs produce acetic acid, a chemical that can then be turned into fuel and plastic. In lab experiments, the bacteria proved much more efficient at harvesting sunlight than plants.The work was presented at the American Chemical Society meeting in Washington.Researchers have been attempting to artificially replicate photosynthesis for many years. Solar panel bugsIn nature, the green pigment chlorophyll is key to this process, helping plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose.But despite the fact that it works, scientists say the process is relatively inefficient. This has also been a big ...
Study: People favor products with more reviews, regardless of what reviews say

Study: People favor products with more reviews, regardless of what reviews say

Science
Aug. 21 (UPI) -- New research suggests that consumers use reviews and ratings by other consumers to drive their purchasing decision-making.The study, published today in Psychological Science, found that people favor products that have more reviews, even if they have lower ratings than an alternative product."It's extremely common for websites and apps to display the average score of a product along with the number of reviews. Our research suggests that, in some cases, people might take this information and make systematically bad decisions with it," Derek Powell, a researcher at Stanford University, said in a press release."We found that people were biased toward choosing to purchase more popular products and that this sometimes led them to make very poor decisions."Researchers studied act...

Aug. 17 (UPI) -- Monday's total solar eclipse is expected to break records, with about 220 million people expected to watch.Some believe the event will inspire the largest temporary migration in human history. With camera-equiped smartphones now ubiquitous, it's also likely to become the most documented event ever.When and whereThe moon's shadow will make landfall in Depoe Bay, Ore., at 10:17 a.m. PDT. The eclipse will move west and south across the United States, tracing what's called the path of totality. By 2:47 p.m. EDT, the moon's shadow will move across Charleston, S.C., and out into the Atlantic Ocean.The shadow's trip across the country will last just 90 minutes. The path will intersect 14 states, including Oregon, Idaho, Montana, Wyoming, Nebraska, Kansas, Missouri, Iowa, Illinois...

To teach kids morals, read books with humans not animals

Science
Aug. 18 (UPI) -- Anthropomorphic, or human-like, animals are often the protagonists of children's books. But new research suggests parents who want their kids to pick up on a story's moral lessons should choose books featuring humans, not animals.Researchers in Canada found four to six-year-olds were more likely to share with their peers after being read a story with human characters."Many people believe children find stories with human-like animals captivating and relatable, but what we're finding is that this is not the case," Dr. Patricia Ganea, associate professor of early cognitive development at the University of Toronto, said in a news release. "Overall, children were more likely to act on the moral of the story when it featured a human character."Researchers read stories about shar...
