When astronaut Scott Kelly was preparing to head to space for a year-long mission on the International Space Station in 2015, he immediately thought about his brother.“This was going to be unique for NASA,” Scott Kelly says in an interview from Space Center Houston. “The first U.S. crew member spending a year in space… maybe there was some value in taking advantage of the fact that…I had an identical twin brother.”His identical twin happens to be former astronaut Mark Kelly, who would be on earth during the same period of time. Scott saw potential to learn something.“I think as an astronaut we have an obligation to promote science, perform the science, to be engaged in science,” he says.The journal publication Science was very interested in the idea. All they needed now was a team of researchers for what would be known as the 850

Two-month-old Mavis Loan’s main meal consists of milk. But long before she arrived, her parents were thinking about her nutrition. “Once she was pregnant, it was instantly ‘what goes into you goes into her.’ And I know once we do start feeding her solids, it'll be very conscious, yes,” says Mavis’ father, Conor Loan. Loan says he and his wife are proactive in making sure their daughter has a healthy diet. “We want her to be healthy, and we don't want any of the, you know, bad side effects of like childhood obesity,” Loan says. Soon, it will be easier for other parents to follow healthy tips for their children. For the first time, the State Departments of Health and Agriculture (USDA) is providing dietary guidelines and recommendations for pregnant women, infants and young children. Recommendations include what and how much they should eat. Dr. Theodore Stathos, a pediatric gastroenterologist at Rocky Mountain Hospital for Children, says he’s relieved to see health guidelines for pregnant women and young children. “When you read through most of the baby primer books, they talk a little bit about nutrition and choices, but they don't limit the quantities of simple sugars and they don't certainly limit the quantities of fats,” Dr. Stathos says. A 2008 study in the medical journal The Lancet found malnutrition from conception to 24 months was linked to obesity, heart disease and other health problems. Lucy Sullivan, founder of the nonprofit 1000 Days, says "if a child is overweight by age 5, there is a great risk the child will be dealing with obesity his entire life. It can be a life sentence." Dr. Stathos says it can be harder to reverse changes as children get older. That's why although the guidelines won't be issued until next year, he says parents can start now making sure their children have a balanced meal “It's very easy to pick them for them, and if you really want to have a cooperative child, as soon as they are able to point and make choices, you can take them to the grocery store with you and give them choices between two healthy things,” Dr. Stathos suggests. 2118

US tennis star Mike Bryan has been fined ,000 for pretending to shoot an on-court line judge with his racket at the US Open Sunday.The doubles player was initially handed a code violation for unsportsmanlike conduct by chair umpire Mariana Alves during his second-round win with brother Bob against Federico Delbonis and Roberto Carballés Baena.Bryan had successfully challenged the line judge's decision after replays on the big screen showed the ball had landed narrowly behind the baseline.After the call was corrected, Bryan mimicked a rifle with his racket and aimed it at the line judge in question.'Meant to be playful'The incident came on the same day that a series of new firearm laws went into effect in Texas just hours after a shooting left seven people dead in the western part of the state.The new gun laws will further loosen gun restrictions in a state that's had four of the 10 deadliest mass shootings in modern US history, including the El Paso shooting last month, when a gunman stormed a Walmart and killed 22 people.The six-time US Open doubles champion later apologized for his actions, saying it was an honest mistake."We won the point and the gesture was meant to be playful," Bryan said in a statement given to the 1255

WASHINGTON — Hiring jumped in February as employers added 273,000 jobs, evidence that the economy was in strong shape before the coronavirus began to sweep through the U.S. The Labor Department said Friday that the unemployment rate fell to 3.5%, matching a 50-year low, down from 3.6% in the previous month. The job gain comes from a survey of payrolls in the second week of February, so the healthy gains pre-date the viral outbreak. 447

United States senators have a knack for talking a lot, sometimes speaking for hours on end. For instance, Sen. Strom Thurmond once led a 24-hour filibuster in opposition of passage of the 1957 Civil Rights Act. But for the impeachment trial of President Donald Trump, senators are being told to be quiet. On Wednesday, Senate leaders Mitch McConnell, R-Ky., and Chuck Schumer, D-N.Y., issued an official memo concerning decorum during the trial. The decorum guidelines tell senators to not engage in conversation with neighboring senators during the trial. Senators also are being prohibited from using electronic devices, like cellphones, on the Senate floor. Senators were also told that the only reading material allowed will be those relevant to the trial. Other bullet points in the memo state that senators should refer to Chief Justice John Roberts as "Mr. Chief Justice." Also, senators were told to stand quietly when Roberts enters and exits the chamber. The trial is expected to go six days a week, with Sundays being the only day off for senators during the trial. 1089
