BOSTON MARATHON-NATION'S PSYCHE
WASHINGTON — A Virginia woman makes a point to get out and go jogging. A Texas mom stays in and snuggles her toddler a little closer. Strains of defiance, tenderness and wariness are woven together as Americans once again do some post-9/11 balancing in the aftermath of the Boston bombings and tainted letters sent to the government. It's more unease for an already bruised American psyche. By Nancy Benac.
BOSTON MARATHON-WAR INJURIES
The bombs that made Boston a war zone also brought battlefield medicine to the victims. A decade of war in Iraq and Afghanistan has sharpened skills and scalpels, leading to dramatic advances that are now being used to treat the 13 amputees and nearly a dozen other patients still fighting to keep damaged limbs. Prosthetics honed from battlefield lessons are now so good that surgeons are choosing them over trying to save a badly mangled leg. By Medical Writer Marilynn Marchione.

WASHINGTON — Senate Republicans backed by a small band of rural-state Democrats scuttle the most far-reaching gun control legislation in two decades, refusing to tighten background checks on firearms buyers or ban assault weapons as they spurn the personal pleas of families of the victims of last winter's elementary school shootings in Newtown, Conn. Critics of the legislation, backed by the political muscle of the NRA, say it infringes on the constitutional right to bear arms. By David Espo.
WASHINGTON — In a capital city on edge, letters sent to President Barack Obama and a Mississippi senator test positive for poisonous ricin in preliminary checks, and authorities chase a stream of reports of other suspicious-looking items sent to senators in Washington and beyond. By Eileen Sullivan and Laurie Kellman.
— RICIN PRIMER — Made from castor beans, the poison ricin causes far more scares than deaths.
BEIRUT — Syria's president accuses the West of backing al-Qaida in Syria and warns it will pay a price "in the heart" of Europe and the United States, suggesting the terror network will be emboldened. Bashar Assad also lashes out at Jordan for allowing thousands of fighters to enter Syria through its borders. The rare TV interview comes as his military fights to reverse rebel advances, with a rocket attack killing at least 12 people in a central village. By Zeina Karam.
DALLAS — American Airlines played catch-up Wednesday, resuming most flights and even adding a handful that weren't on the schedule to help passengers stranded by a massive technology failure that grounded the carrier's entire U.S. fleet a day earlier. As passengers got back in the air, questions lingered about whether the system that runs many of the airline's daily operations will be adequate after American merges with US Airways to form the world's largest airline. By David Koenig.

RAMALLAH, West Bank — The Palestinians are turning to their fledgling high-tech sector as they try to lay the groundwork for an independent state.

By Daniela Berretta.
WALAWEYN, Somalia — Abdi Ali and his girlfriend Anisa arrive in a run-down town north of Mogadishu, having pretended not to know each other during the trip. Their secret mission: to elope in defiance of Anisa's parents' wishes for her to marry a cousin in America. Now that Islamic extremists have been pushed out of almost all of Somalia's cities and towns, elopements — banned under the insurgents — are soaring in Somalia. By Abdi Guled.
CENTRAL AFRICAN REPUBLIC-REBEL HOTEL
BANGUI, Central African Republic— Rebel fighters who overthrew the president have set up shop in the capital's sole luxury hotel. Now, rebels armed with rocket-propelled grenades and Kalashnikov rifles walk among businessmen in traditional embroidered robes and diplomats who come to meet with the man who rules mineral-rich Central African Republic. By Krista Larson.
KIROV, Russia — Alexei Navalny, a Russian opposition leader facing trial on charges of embezzlement, shot to prominence through outing public corruption via his blog and Twitter. At the beginning of what his supporters say is a politically motivated trial, the AP looks at his campaigns that have provoked official wrath. By Max Seddon.
PUERTO RICO-DOCTOR EXODUS
SAN JUAN, Puerto Rico — Going to the doctor in Puerto Rico has for years often meant getting in line. Now, it might mean getting on a plane. Doctors and nurses are fleeing for better salaries on the U.S. mainland. Many of their patients are finding they have no other choice but to follow them off the island. One example: The number of cardiologists has fallen from 400 to 150. By Danica Coto.
DISTRICT ATTORNEY DEAD-TEXAS
KAUFMAN, Texas — The wife of a former North Texas justice of the peace implicates her husband in the shooting deaths of a local district attorney, his wife and an assistant prosecutor. An arrest affidavit reveals Kim Lene Williams told investigators that her husband, Eric Lyle Williams, was the triggerman in the slayings. By Danny Robbins.
CHARLESTON, S.C. — Mark Sanford's attempted political comeback hinges on the mostly conservative voters of South Carolina's Lowcountry accepting his contrition and forgiving him for his past infidelity and political mistakes. But will voters be willing to do that after his ex-wife accuses him in court documents of trespassing at her home? And will his opponent for the congressional seat, who has so far avoided discussing the scandal that enveloped him as governor, now try to make hay of it on the campaign trial? By Bruce Smith.
PHOENIX — After the Connecticut school shooting, cities around the country held gun buyback programs where people bring old firearms and get cash and gift cards to get weapons off the street. Arizona, however, is now a step away from essentially doing away with the programs. Lawmakers have approved a bill that would ban cities from destroying the weapons and require them to sell the guns — part of a broader movement among gun-rights lawmakers to limit gun buybacks. By Bob Christie.

GAY THERAPY BAN
SAN FRANCISCO — A federal appeals court grapples with California's first-in-the-nation bid to bar licensed mental health professionals from offering therapies aimed at making gay and lesbian teenagers straight. The ban on so-called reparative therapy was supposed to take effect at the beginning of the year, but has been on hold pending resolution of two lawsuits seeking to overturn it. By Lisa Leff.
ANCHORAGE, Alaska — A soldier and an instructor at the Army's Alaska Northern Warfare Training Center descended 145 feet to a 15-foot space inside an Alaska glacier to extract the body of a 9-year-old boy who fell through the hole on his snowmobile. The men on Sunday shoveled 3,000 pounds of snow into bags lifted out by soldiers at the surface to reach the body of Shjon Brown. By Dan Joling.
HEALTH OVERHAUL ANGST
WASHINGTON — A senior Democratic senator who helped write President Barack Obama's health care law stuns administration officials, saying openly he thinks it's headed for a "train wreck" because of bumbling implementation. Senate Finance Committee Chairman Max Baucus is the first top Democrat to publicly voice fears about the law's rollout. By Ricardo Alonso-Zaldivar.
SUPREME COURT-OVERSEAS ABUSES
WASHINGTON — The Supreme Court rules that foreign victims of human rights abuses cannot use American courts to seek accountability and monetary damages for their suffering. It's a major victory for corporations that have been sued in the U.S. over their alleged role in foreign atrocities, and largely unravels a more than 30-year-old strategy by human rights lawyers. By Mark Sherman.
EUROPE-SINKING AUTO SALES
Europe's auto market is in freefall. Once the motor for Europe's economy, the car industry has fallen victim to the region's widening recession and soaring unemployment. Carmakers have suffered 18 straight months of declining sales as people worried that they might soon be out of a job put off making big purchases. Even in Germany, one of Europe's strongest economies, new car sales plunged 13 percent during the first three months of the year. By Colleen Barry.
Amazon.com is giving viewers a chance to vote on its lineup of new TV shows, scuttling a secretive, money-wasting process once reserved for Hollywood taste-makers. The online retailing giant will let visitors from the U.S, U.K. and Germany watch, rate and critique 14 pilot episodes the company has bankrolled. Viewer comments will help the company decide which ones — if any — get the green light. Amazon's foray into TV production is unique in the way it saves money. Every spring, as part of a rather wasteful Hollywood ritual, networks like ABC, NBC, CBS and Fox order dozens of pilots, only to have a handful made into series. By Ryan Nakashima.
