The remains of an ancient ape found in a Bavarian clay pit suggest that humans’ ancestors began standing upright millions of years earlier than previously thought, scientists said Wednesday.An international team of researchers says the fossilized partial skeleton of a male ape that lived almost 12 million years ago in the humid forests of what is now southern Germany bears a striking resemblance to modern human bones. In a paper published by the journal Nature, they concluded that the previously unknown species — named Danuvius guggenmosi — could walk on two legs but also climb like an ape.The findings “raise fundamental questions about our previous understanding of the evolution of the great apes and humans,” said Madelaine Boehme of the University of Tuebingen, Germany, who led the research.The question of when apes evolved bipedal motion has fascinated scientists since Charles Darwin first argued that they were the ancestors of humans. Previous fossil records of apes with an upright gait — found in Crete and Kenya — dated only as far back as 6 million years ago.Boehme, along with researchers from Bulgaria, Germany, Canada and the United States, examined more than 15,000 bones recovered from a trove of archaeological remains known as the Hammerschmiede, or Hammer Smithy, about 70 kilometers (44 miles) west of the Germany city of Munich.Among the remains they were able to piece together were primate fossils belonging to four individuals that lived 11.62 million years ago. The most complete, an adult male, likely stood about 1 meter (3 feet, 4 inches) tall, weighed 31 kilograms (68 pounds) and looked similar to modern-day bonobos, a species of chimpanzee.“It was astonishing for us to realize how similar certain bones are to humans, as opposed to great apes,” Boehme said.Thanks to several well-preserved vertebra, limb, finger and toe bones, the scientists were able to reconstruct how Danuvius moved, concluding that while it would have been able to hang from branches by his arms, it could also straighten its legs to walk upright.“This changes our view of early human evolution, which is that it all happened in Africa,” Boehme told The Associated Press in an interview.Like humans, Danuvius had an S-shaped spine to hold its body upright while standing. Unlike humans, though, it had a powerful, opposable big toe that would have allowed it to grab branches with its foot and safely walk through the treetops.Fred Spoor, a paleontologist at the Natural History Museum in London, called the fossil finds “fantastic” but said they would likely be the subject of much debate, not least because they could challenge many existing ideas about evolution.“I can see that there will be a lot of agonizing and re-analysis of what these fossils mean,” said Spoor, who wasn’t involved in the study. 2833

The Trump administration is proposing tariffs on up to .4 billion worth of French imports — including Roquefort cheese, handbags, lipstick and sparkling wine — in retaliation for France’s tax on American tech giants like Google, Amazon and Facebook.The Office of the U.S. Trade Representative charged Monday that France’s new digital services tax discriminates against U.S. companies. The trade office will accept public comments on the tariffs, which could hit 100%, through Jan. 6 and hold a hearing Jan. 7.The French tax is designed to prevent tech companies from dodging taxes by putting headquarters in low-tax European Union countries. It imposes a 3% annual levy on French revenues of digital companies with yearly global sales worth more than 750 million euros (0 million) and French revenue exceeding 25 million euros.The U.S. also criticized the French tax for targeting companies’ revenue, not their profits, and for being retroactive.The decision to pursue tariffs “sends a clear signal that the United States will take action against digital tax regimes that discriminate or otherwise impose undue burdens on U.S. companies,” U.S. Trade Representative Robert Lighthizer said.His agency investigated the French tax under Section 301 of the Trade Act of 1974 — the same provision the Trump administration used last year to probe China’s technology policies, leading to tariffs on more than 0 billion worth of Chinese imports in the biggest trade war since the 1930s.Lighthizer warned that the U.S. is also exploring whether to pursue Section 301 investigations into digital taxes introduced by Austria, Italy and Turkey.The decision to target France got bipartisan endorsement from Iowa Republican Sen. Chuck Grassley and Oregon Democratic Sen. Ron Wyden. In a joint statement, they assailed the French digital tax as “unreasonable, protectionist and discriminatory.”The tech trade group ITI said it welcomed the administration’s decision and urged continued negotiations on international taxes under the auspices of the Organization for Economic Cooperation and Development.The tariff announcement is likely to increase tension between the United States and Europe. The U.S. is already readying tariffs on .5 billion in EU imports over illegal subsidies for the European aircraft giant Airbus. The World Trade Organization on Monday 2367

The statistics around maternal mortality in the United States are startling. America has the highest maternal mortality rate out of any developed country in the world. Today, a woman in the U.S. is 50 percent more likely to die from giving birth to a child than her mother was, and if you are a woman of color you are 3 to 4 times more likely than that.At Rush University Hospital in Chicago, neonatal intensive care nurse and educator Christie Lawrence has dealt with maternal mortality both professionally and personally. “My cousin, Chante, she was a young healthy mother, 18 years old,” Lawrence says. “Actually, she had no risk factors that we knew of.” Ten years ago, Lawrence was at work when her cousin went into labor at another hospital. “I received a call to say, ‘Chante is in labor, we are going to have a baby today.’ Then, a couple of hours later, a turn of events,” she recalls. “Her mom is screaming, ‘I need you to get here quick! Something has gone terribly wrong.’” The healthy 18-year-old mom suddenly went into cardiac arrest while giving birth to her son, and she died. “It was very shocking, very shocking for my family to see that whole turn of events,” said Lawrence. “We were expecting everything to be normal.”Her cousin’s death was caused by medication that was administered to her the wrong way. When Chante went in labor, she was a first-time mom and had no access to transportation to the hospital, so an ambulance was called. The ambulance took her to a hospital that was different than the one she had been going to for care during her pregnancy. Lawrence believes that may have played into the quality of care her cousin received, and ultimately, the mistake that was made at the hospital. It all led to the death of Lawrence’s cousin, which she says was fully preventable. Unfortunately, Chante’s case isn’t unique. These kinds of mistakes are happening at an alarming rate across the country. According to a Center for Disease Control report published this year, 60 percent of all pregnancy-related deaths in this country are fully preventable. Hospitals and healthcare providers around the country are working to implement new procedures to reduce the maternal mortality rate. At Rush University, for example, it’s trying a new program that checks up on babies and new moms just three weeks after leaving the hospital. Typically, in the past, doctors recommended a three-week check-up that focused on the newborn. But with this new program called Rush Family Connect, a nurse will go to the parent’s home and give equal attention to mom. The hope is that any post-pregnancy complication can be caught early, since the top causes of maternal mortality are actually post-delivery complications. Additionally, this year, the Joint Commission has issued a new mandate and standard. By July 1, 2020, all hospitals must have life-saving medications immediately available and must plan rapid release of blood supplies for transfusions. Doctors and nurses at hospital maternity units must have training drills responding to a hemorrhage crisis, which is one of the top cases for fatal deliveries. While hospitals and healthcare providers work to reduce the dangers mothers are facing, Lawrence believes mother have some power over their outcomes. “Just being a great advocate for yourself is one of the biggest things that I would tell any new mom,” said Lawrence. “If you feel like something is not right, if you feel like something is wrong, make people listen to you. And if you feel like that person won’t listen to you, then you have to go up the chain of command in that system or you have to find someone who is willing to listen.”It’s advice Lawrence wishes she could go back in time and tell her cousin. 3754
