Paragraph: Fitness experts say users of the fitness machine, which is a favorite among Army Rangers, Navy Seals, and "The Biggest Loser" television series, reap total body, calorie-busting rewards. "It's a great and tough cardio piece," said Neal Pire, an exercise physiologist with the American College of Sports Medicine. "Picture a step mill that combines the lower and upper body, and you have Jacobs Ladder. Except instead of steps, you have rungs." Because the user climbs with arms as well as legs more muscles are working and more calories are burned. "As a rule the more muscle mass you utilize during any activity, the greater the oxygen consumed, which is directly correlated to the calories you consumed," said Pire, president of Inspire Training Systems, in New Jersey. "Unlike stair climbers, you can't hold on to the sides." Jacobs Ladder was invented by Steve Nichols, a fitness champion who injured his knees and back, according to Bob Palka, president of Jacobs Ladder, LLC. "He wanted to come up with a good workout that didn't impact back and knees." said Palka, who bought the patent and assets from Nichols in 1994. "Effectively it's just climbing a ladder," Palka said. People using the machine are placed at a 40-degree angle to put the spine in a more neutral position, relieve the back of stress and engage core muscles. Palka said on Jacobs Ladder the person's body weight is lifted over a 12-inch (30.5-centemeter) step for fuller range of motion than the eight-inches of a step mill. "You control the speed," he said." The faster you go the faster the runners (on the ladder) come." Palka said about 50 to 60 percent of his Jacobs Ladders go to health clubs; some 10 to 15 percent go to the military and physical therapy facilities, respectively. Jacobs Ladder landed a recurring role on the TV show "The Biggest Loser" after trainer Jillian Michaels fell in love with it. "It tends to get your heart rate up," said Palka, adding that other users, such as the FBI and the Army Rangers, are drawn to the intensity of the workout. John Trail, general manager of a Fitness First health club in Arlington, Virginia, uses Jacobs Ladder in functional circuit and interval training. "You can go for time or you can go for feet," said Trail. "It's not a fast-moving piece, but the fact that you're using every muscle group means you can do 100 feet, rest, jump off, do 10 kettlebell swings, 10 short interval sprints, and burn a lot more calories than you would on an elliptical." Trail said a rock climbing buddy likes to climb Jacobs Ladder wearing a back pack for an endurance workout. A self-described competitive person, Trail has even raced with it. "We have two machines side-by-side, so we'll go for 1,000 feet as fast as possible," he said. "In under 10 minutes you can get a really good workout." He also uses it on clients with joint issues to get their heart rates up quickly. But despite its virtues, Pire said it's unlikely Jacobs Ladder will supplant the treadmill anytime soon. "The tougher the machine, the more seldom you see it," he said. "I haven't seen many seniors hop on. The older population is concerned about balance and falling. And there's some skill involved in climbing a ladder. But fans are ardent. "Those who use it are almost religious," he said. Claim: Jacobs Ladder climbers reap tough fitness rewards.
Jacobs Ladder, a moving, angled, climbing machine, may be named after the Biblical stairway to heaven, but it packs such a challenging workout people have dubbed it the stairway to hell.

Paragraph: Bryant's action came despite a federal judge's ruling last year that struck down a less-restrictive law limiting abortions in the state. The New York-based Center for Reproductive Rights called the new measure "cruel and clearly unconstitutional" and said it would sue Mississippi to try to block the law from taking effect on July 1. After a bill signing ceremony at the state Capitol, Bryant told reporters that he's not worried about lawsuits. "They don't have to sue us. It's up to them," Bryant said. "If they do not believe in the sanctity of life, these that are in organizations like Planned Parenthood, we will have to fight that fight. But it is worth it." Mississippi is one of several states that have considered bills this year to ban abortions once a fetal heartbeat is found. Abortion opponents are emboldened by new conservatives on the Supreme Court and are seeking cases to challenge Roe v. Wade, the court's 1973 ruling that legalized abortion nationwide. A federal judge in 2018 struck down a Mississippi law that would ban most abortions after 15 weeks of pregnancy, saying it is unconstitutional. The ruling came in a lawsuit filed by the only remaining abortion clinic in Mississippi. "Lawmakers didn't get the message," Hillary Schneller, staff attorney for the Center for Reproductive Rights, said in a statement Thursday. "They are determined to rob Mississippians of the right to abortion, and they are doing it at the expense of women's health and taxpayer money. This ban just like the 15-week ban the governor signed a year ago is cruel and clearly unconstitutional." The law that Bryant signed Thursday says a physician who performs an abortion after a fetal heartbeat is detected could face revocation of his or her Mississippi medical license. It also says abortions could be allowed after a fetal heartbeat is found if a pregnancy endangers a woman's life or one of her major bodily functions. The House and Senate both rejected efforts to allow exceptions for pregnancies caused by rape or incest. Georgia and Tennessee are among the states considering similar bills. Kentucky's law banning abortion after the detection of a heartbeat was immediately challenged by the American Civil Liberties Union when Republican Gov. Matt Bevin signed it on March 14, and a federal judge temporarily blocked it. A federal judge on Wednesday also blocked another Kentucky law that would ban abortion for women seeking to end their pregnancies because of the gender, race or disability of the fetus. Dr. Leana Wen, a physician who is president of Planned Parenthood Federation of America, said in a statement Thursday that the new Mississippi law "is a dangerous policy that criminalizes a safe, standard medical procedure and will endanger women's lives." "Patients must be empowered to make their own health care decisions, in consultation with their doctor and their family, and doctors must be able to provide health care to our patients without the threat of prison time," Wen said. "We cannot accept a world where the right to abortion care depends on where you live or how much money you make." Jameson Taylor, vice president for policy at the conservative Mississippi Center for Public Policy, praised Bryant for signing the bill. "The heartbeat bill is popular because everyone knows a heartbeat is a sign of life," Taylor said in a statement. "Intellectual and scientific honesty demands a reconsideration of Roe, a 50-year-old decision based on old science. 3-D and 4-D ultrasounds are showing women that their unborn child is alive." ____ Follow Emily Wagster Pettus on Twitter at http://twitter.com/EWagsterPettus . Claim: Mississippi governor signs 'heartbeat' abortion law.
Mississippi Gov. Phil Bryant on Thursday signed one of the strictest abortion laws in the nation a measure that bans most abortions once a fetal heartbeat can be detected, about six weeks into pregnancy.

Paragraph: Scientists at Vienna University medical school's Institute of Hygiene and Applied Immunology came to the conclusion after analyzing the water quality at 21 "holy" springs and 18 fonts at churches and chapels at various times of year. Only 14 percent of the water samples from holy sources showed no fecal contamination, and none of the springs could be recommended as a source of drinking water, the study presented to a conference in Vienna this week found. The springs held not only fecal contamination - likely the result of poor hygiene - but many also had agricultural nitrates and bugs that can cause inflammatory diarrhoea. "We need to warn people against drinking from these sources," microbiologist Alexander Kirschner said in the study. Kirschner said the healing effects ascribed to holy sources arose from the hygienic conditions of the Middle Ages, when water quality in urban areas was generally so poor that people constantly contracted diarrhoea or other conditions. "If they then came across a protected spring in the forest that was not as polluted and drank from it for several days, their symptoms would disappear. So although in those days they were drinking healthier water, given the excellent quality of our drinking water today, the situation is now completely reversed." The study noted some ways to help address the problem, including regularly replacing holy water in church fonts. One Italian priest has invented a holy water dispenser that dispenses drops of holy water rather than having the faithful dip a hand in, it noted. Claim: Holy water in Austria unsafe to drink: researchers.
Holy water at religious shrines and churches in Austria is often contaminated with fecal matter and bacteria, researchers have found, advising the faithful not to drink it, especially in hospital chapels.
