NEW YORK (AP) - Department of Justice lawyers filed court papers Friday again asking a federal appeals court to delay lifting age restrictions and prescription requirements on an emergency contraceptive popularly known as the morning-after pill. The papers seek to delay implementation of a judge's April 5 ruling lifting restrictions on the drugs, including the medications sold under the brand name Plan B, setting the stage for another court showdown between President Barack Obama's administration and women's health activists over access to the contraceptive.

Currently, only people age 17 or older can buy the contraceptive without a prescription, although the Food and Drug Administration announced in late April that it would begin allowing one newer version of the drug, Plan B One-Step, to be sold over the counter to people as young as 15 as long as they present photo ID. That accommodation only further agitated U.S. District Court Judge Edward Korman, who in his opinion on April 5 said that U.S. Secretary of Health and Human Services Kathleen Sebelius had wrongly let politics trump science when she overruled an FDA decision in 2011 that emergency contraception based on the hormone levonorgestrel could be sold safely to people of all ages without a prescription. In a follow-up ruling, the judge said that the contraceptive "would be among the safest drugs available to children and adults on any drugstore shelf." He called the FDA's deal to allow some over-the-counter sales of Plan B One-Step a "sweetheart agreement" for the medication's manufacturer, Teva Pharmaceuticals.

He noted that it would continue to restrict access to cheaper brands of the drug and be a hardship to the many young people who don't have driver's licenses. The 2nd Circuit Court of Appeals, in New York, is scheduled to begin considering on Tuesday whether to allow the judge's ruling to take effect immediately or delay it while further appeals are pending. The Department of Justice, in its motion for a stay, argued that the judge overstepped his authority in ordering the drugs to be made available. It also said that maintaining the status quo while the case is on appeal would prevent market confusion over the status of the drugs. Lawyers for a group of women and parents who have sued to broaden access to the contraceptives said in court papers that any further delay in their availability would harm "countless" women by leaving obstructions in place.

While the case is ostensibly about rules limiting the access of teenagers to the drug, it has a practical impact on older women as well because the age restrictions mean that the contraceptives must be kept behind locked pharmacy counters and therefore aren't always available in the emergencies for which they are intended. The drugs can prevent pregnancy if taken within 72 hours of sex, but they are more effective the sooner they are taken.

LAKELAND, Minn. (AP) - A Minnesota teenager whose farewell song became a YouTube sensation has died after a fight with bone cancer. Zach Sobiech died Monday at his Lakeland home. His mother, Laura, said on the CaringBridge website that he was surrounded by his family and girlfriend.

The 18-year-old was diagnosed with osteosarcoma in November 2009. When he learned last year he didn't have much longer to live, his mother suggested he write farewell notes to his loved ones. Instead, he wrote music. His farewell song, "Clouds," has received more than 4 million views on YouTube in just two weeks. The song is on iTunes, with proceeds going to the Zach Sobiech Osteosarcoma Fund. Zach's family is declining interviews but said in a statement they felt blessed by Zach's "amazing presence" in their lives.

BOSTON (AP) - In a medical first, scientists used plastic particles and a 3-D laser printer to make an artificial airway splint to save the life of a baby boy. The little Ohio boy used to stop breathing every day because of a birth defect that caused his airway to collapse. Now he breathes normally, thanks to the first-of-a-kind implant he received at the University of Michigan last year, when he was 3 months old.

To make the device, doctors use a computer-guided laser printer that stacks and fuses thin sheets of biodegradable plastic to form the airway tube. It's the latest advance in the field of regenerative medicine, making body parts in the lab. The case is described in Thursday's New England Journal of Medicine.

RIYADH, Saudi Arabia (AP) - Saudi Arabia has confirmed four new cases of a deadly new respiratory virus related to SARS that appears centered in the Arabian Peninsula but that has also been reported in Europe. The official Saudi Press Agency said Tuesday that one patient was treated and released from a hospital, while three others remain under medical care.

Saudi authorities have reported nearly 30 cases since the virus was identified last year. Other cases have appeared in France, Germany and Britain, possibly linked to travel in the Gulf region. The novel coronavirus has killed at least 18 people since September 2012. The new virus is related to SARS, which killed some 800 people in a global epidemic in 2003, and belongs to a family of viruses that most often causes the common cold.

NEW DELHI (AP) - The Indian government has announced the successful development of a low-cost vaccine proven effective in preventing the deadly diarrhea-causing rotavirus. Rotavirus is the most lethal cause of childhood diarrhea and is responsible for the deaths of 100,000 Indian children annually.

The Department of Biotechnology said Tuesday that phase III trials of Rotavac showed a 56 percent decline in severe diarrhea caused by the rotavirus. Vaccine producer Bharat Biotech has said it would sell Rotavac for $1 a dose. Health officials said that is a major discount over the current vaccines and could make it possible for many developing countries to start vaccination programs.
