Paragraph: Hyperemesis gravidarum is estimated to affect about one to three percent of pregnant women and can result in nausea and vomiting so acute that hospitalization is required. It is thought to be caused by pregnancy hormones, but doctors aren't sure why some women experience worse symptoms than others. The condition usually begins in the early weeks of pregnancy and in many cases, subsides by about 20 weeks. But for some women, the effects may persist until the baby is born. The condition can be "absolutely devastating," said Dr. Roger Gadsby of Warwick University, who has studied the issue for decades. "Your life is on hold while the symptoms are present," he said, noting that some pregnant women may vomit dozens of times per day and be restricted to bed rest. Kensington Palace made the pregnancy announcement Monday, saying the duchess was not feeling well enough to attend an official engagement later in the day. Kate is being cared for at her Kensington Palace home in London. There was no word of when the baby is due. She and Prince William already have two children: Prince George, 4 and Princess Charlotte, 2. In 2012, Kate was hospitalized for several days when she was believed to be suffering from dehydration. There is no evidence that the nausea and vomiting from severe morning sickness will affect the baby's future health. Women with the condition actually have a slightly lower risk of miscarriage, according to Britain's Royal College of Obstetricians and Gynaecologists. In severe cases, however, babies can be born with lower than expected birthweight. Women with the condition are advised to eat small meals often, to avoid any foods or smells that trigger symptoms and to consult their midwife or doctor if their symptoms do not subside. If treatment requires hospitalization, women are typically given vitamins, steroids and anti-nausea drugs intravenously. Patients are also sometimes treated with shots of heparin, to thin their blood: pregnant women are at increased risk of developing blood clots in their legs, and being dehydrated further elevates the risk. Gadsby said he would expect doctors to be able to treat the duchess at Kensington Palace and that there shouldn't be any lasting effects. She would likely have to cut back on her royal schedule, though. "As long as the mom receives adequate treatment, the mom is usually fine and the baby is fine," he said. ___ This Associated Press series was produced in partnership with the Howard Hughes Medical Institute's Department of Science Education.

Prince William and his wife, the Duchess of Cambridge, are expecting their third child. And for the third time as with her previous two pregnancies the former Kate Middleton is suffering from hyperemesis gravidarum, or severe morning sickness.

Paragraph: A deadly fungal disease devastated amphibians in Central America more than a decade ago, quieting some mountain streams. But new research shows evolution may have saved the day and the frogs. In El Cope, Panama, at least four species disappeared including the red-striped Rio San Juan robber frog. Four other species lost at least 88 percent of their population from a disease-causing fungus that hit Panama hard from 2004 to 2007. The fungus has also been blamed for wiping out amphibian populations in California's Sierra Nevada and parts of Australia. In the last few years, croaks have been heard in once quiet Panama streams. The critters are by no means recovered since they are still infected with the fungus, but they are alive and growing in numbers, according to a new study in Thursday's journal Science . "It's so easy to lose hope when you've walked the same stretch of stream year after year, hoping to see a hint of the amazing diversity you once saw there," study co-author Corinne Richards-Zawacki, a University of Pittsburgh biologist, said in an email. "So you can imagine how good it feels to be able to report some good news from the field." The recovery is not everywhere and it's at best modest, cautioned lead author Jamie Voyles, a disease ecologist at the University of Nevada, Reno. One of the frogs making the most noticeable comeback is the hard-to-catch rocket frog, named because it is so quick, she said. Voyles and Richards-Zawacki wanted to find out why the amphibians survived. They initially figured the disease weakened. But after testing old and new disease samples on frogs, they found the disease was as dangerous as ever. To their surprise, the frogs and toads were fighting back better. The fungal disease attacks their skin secretions and recently the frogs showed a two- to five-fold improvement in the amphibians' ability to limit the fungus' growth. The disease is still there, but it does less damage, Voyles said. While this research is important, the findings aren't too surprising because past studies have shown that as bad as disease outbreaks get, they play a tiny role in species extinction, said Andrew Blaustein at Oregon State University, who wasn't part of the study. Evolution allows species to resist completely succumbing to the nastiest diseases. "So, yes there is hope," Blaustein said in an email. ___ Follow Seth Borenstein on Twitter at @borenbears .

After years of silence, the rhythmic dee-dee-deeps of frogs and toads are returning in parts of Panama.

Paragraph: Under her leadership, the organization gained in membership, donor support and political clout but found itself in constant conflict with social conservatives for its role as the leading abortion provider in the United States. The organization provides a range of health services at clinics nationwide, including birth control, cancer screenings and tests for sexually transmitted diseases. Republicans in Congress tried repeatedly to cut off federal funding that helps subsidize Planned Parenthood's services to some patients, and several congressional committees investigated the organization's role in providing post-abortion fetal tissue to researchers. In a statement Friday, Richards said she would remain engaged in political activism ahead of the November elections. "There has never been a better moment to be an activist," said Richards, who was a featured speaker in Las Vegas at one of last weekend's largest women's marches. Richards, 60, is the daughter of former Texas Gov. Ann Richards. Before joining Planned Parenthood, she was a union organizer and deputy chief of staff to U.S. Rep. Nancy Pelosi, among other roles. Reaction to Richards' announcement reflected the divisive nature of the debate over Planned Parenthood's role. Pelosi, the House minority leader, hailed her as "a portrait of energy, intellect, and determination" whose impact transcended reproductive rights. "As an organizer, activist, and leader, Cecile has helped launch a nationwide movement to defend and advance women's rights, and in doing so, she has inspired countless women to march, vote, run, and win." Pelosi said. Anti-abortion activists seized the occasion to demonize Richards. Her legacy "is one of death and destruction," said Kristin Hawkins, president of Students for Life of America. "She leaves broken lives in her wake." Many of the key battles for Richards and Planned Parenthood were waged in Congress, where Republicans repeatedly, though unsuccessfully, sought ways to cut off its federal funding. GOP lawmakers also organized multiple investigative committees after anti-abortion activists released secretly recorded videos in 2015 that they said showed Planned Parenthood employees illegally selling fetal tissue for profit. Planned Parenthood emphatically denied that claim. Thus far there's been no formal finding by Congress of wrongdoing by the organization, but the dispute over the allegations is not settled. Justice Department officials confirmed in December that the department was considering investigations related to the transfer of fetal tissue. There was no immediate word of a possible successor to Richards. Planned Parenthood said it would be announcing future plans after a meeting of its board of directors next week. Planned Parenthood said Richards helped grow its base of supporters from 3 million to 11 million and build its donor base to its largest ever. She oversaw a notable expansion of services to LGBT people, including sharp increases in HIV testing and the provision of hormone therapy for transgender patients. Richards' resignation precedes the scheduled publication of her memoir, "Make Trouble," in April. Claim: Cecile Richards stepping down as Planned Parenthood leader.
Cecile Richards, who led Planned Parenthood through 12 tumultuous years, is stepping down as its president.
