• First person diagnosed with Ebola in U.S. dies

WASHINGTON - The first person diagnosed with Ebola in the U.S. died Wednesday despite intense but delayed treatment, and the government announced it was expanding airport examinations to guard against the spread of the deadly disease.

The checks will include taking the temperatures of hundreds of travelers arriving from West Africa at five major American airports.

The new screenings will begin Saturday at New York's JFK International Airport and then expand to Washington Dulles and the international airports in Atlanta, Chicago and Newark. An estimated 150 people per day will be checked, using high-tech thermometers which don't touch the skin.

The White House said the fever checks would reach more than 9 of 10 travelers to the U.S. from the three heaviest-hit countries - Liberia, Sierra Leone and Guinea.

President Barack Obama called the measures "really just belt and suspenders" to support protections already in place. Border Patrol agents now look for people who are obviously ill, as do flight crews, and in those cases the Centers for Disease Control and Prevention is notified.

• Health website contains at least one goof

WASHINGTON - The Obama administration unveiled a new version of HealthCare.gov on Wednesday, with some improvements as well as at least one early mistake and a new challenge.

Officials also said HealthCare.gov won't display premiums for 2015 until the second week of November. Open enrollment season runs Nov. 15 through Feb. 15. Coverage can start as early as Jan. 1.

On the plus side, the health insurance website will feature a streamlined application for most of those signing up for the first time. Seventy-six screens in the online application have been reduced to 16, officials said. The site has been also optimized for mobile devices.

The goof is a mistranslation in large type on the home page of the Spanish-language version of the site. It's the very first word on the page. Trying to translate "get ready," someone came up with the wrong word in Spanish.

The Spanish-language site had lots of problems last year, ranging from technology issues to clunky translations that left some native speakers puzzled. The administration struggled to sign up Hispanics, the nation's largest minority and more likely to be uninsured than other ethnic groups.

• Turkish inaction on Syria frustrates U.S. and allies

ISTANBUL - As U.S. generals and Secretary of State John Kerry warn that a strategic Syrian border town could fall to Islamic State militants, the Turkish military has deployed its tanks on its side of the frontier but only watched the slaughter.

Turkey's inaction despite its supposed participation in a coalition forged to crush the extremist group is frustrating Washington and its NATO allies, and reviving a rebellion by Turkish Kurds.

Amid fears the Kurdish town of Kobani could fall any day, U.S. and NATO officials are traveling to Turkey on Thursday to press negotiations for more robust Turkish involvement in the coalition.

But Turkey is taking a hard line, insisting that it will only consider involvement in military action as part of a broader strategy for ending the rule of Syrian President Bashar Assad. The U.S. and its allies want to keep the focus on the Islamic State group, which they say poses a more global threat.

Emphasizing the U.S. position, Kerry said Wednesday that although the Obama administration is "deeply concerned about the people of Kobani," preventing the town's fall to Islamic State militants was not a strategic objective for the U.S.

• Flight diverted over woman's bomb threat

NEW ORLEANS - The FBI said federal prosecutors won't charge a California woman who was removed from a plane in New Orleans after officials said she made a bomb threat during a SkyWest flight.

Jefferson Parish Sheriff's Office Col. John Fortunato said the 31-year-old from Anaheim is hospitalized under a protective custody order. Fortunato said she made statements other passengers found threatening.

FBI spokeswoman Mary Beth Romig said federal investigators questioned the woman and decided against filing charges. Romig said earlier that the FBI did not consider the threats credible.

SkyWest spokeswoman Marissa Snow said 70 passengers were on Wednesday's Flight 6388 from Houston to Miami.

It was diverted to the New Orleans airport shortly after 9:15 a.m., leaving New Orleans for Miami about 11:15 a.m.

• Three win Nobels for super-zoom microscopes

STOCKHOLM - Three researchers won a Nobel Prize on Wednesday for giving microscopes much sharper vision than was thought possible, letting scientists peer into living cells with unprecedented detail to seek the roots of disease.

The chemistry prize was awarded to U.S. researchers Eric Betzig and William Moerner and German scientist Stefan Hell. They found ways to use molecules that glow on demand to overcome what was considered a fundamental limitation for optical microscopes.

Betzig, 54, works at the Howard Hughes Medical Institute in Ashburn, Virginia. Hell, 51, is director of the Max Planck Institute for Biophysical Chemistry in Goettingen, Germany, and also works at the German Cancer Research Center in Heidelberg. Moerner, 61, is a professor at Stanford University in California.

Their work, done independently and extending back to the 1980s, led to two techniques which were first demonstrated in 2000 and 2006.

Previously, a calculation published in 1873 was thought to define the limit of how tiny a detail could be revealed by optical microscopes.

• N.Y. court hears arguments that chimps have rights

ALBANY, N.Y. - A state appeals court will decide in coming weeks whether chimpanzees are entitled to "legal personhood" in a case that could lead to expanded rights for animals such as gorillas, elephants and dolphins, according to the lawyer advocating for a 26-year-old chimp named Tommy.

Attorney Steven Wise argued before a five-member mid-level appeals court Wednesday on behalf of Tommy, who lives alone in a cage in upstate Fulton County. A trial-level judge has refused a request by Wise and his Nonhuman Rights Project to have Tommy released to join other chimps at a Florida sanctuary that mimics their natural habitat.
