Canberra, Jul 19 (AP/UNB) — A fisherman said on Wednesday he was looking for the author of a message in a bottle found off the southern Australian coast 50 years after it was written.

Paul Elliot told Australian Broadcasting Corp. that he and his son Jyah found the bottle on the west coast of Eyre Peninsula in South Australia state while fishing.

Elliot said he was looking for the author Paul Gibson, who described himself in the note as a 13-year-old English boy traveling in a cruise ship along the southern Australian coast from Fremantle in the west to Melbourne in the east.

Government oceanographer David Griffin said the bottle could not have remained afloat for 50 years off the south coast because "the ocean never stays still."

Griffin suspected that the bottle had been buried on a beach for years then refloated by a storm.

"If it had been dropped in anywhere in the ocean somewhere south of Australia, then there's no way it's going to stay actually at sea moving around for more than a year or two," Griffin said.

The author gave his position as "1000 miles east of Fremantle." However it is not clear whether the author actually meant 1,600 kilometers (1,000 miles) out of Fremantle, which would have included a journey south along the west coast before turning east.

Hundreds of thousands of Britons migrated to Australia in the 1960s with the Australian government subsidizing their fares. Children traveled for free.

But a quarter of them returned to Britain within a few years when life in Australia fell short of their expectations.

Beijing, July 19 (Xinhua/UNB) -- Chinese scientists will begin the second-phase clinical trial of an HIV vaccine on 160 volunteers, Friday's China Daily reported.

The candidate vaccine, DNA-rTV, relies on replication of the DNA of HIV to stimulate effective immunization, according to Shao Yiming, a chief HIV researcher at the Chinese Center for Disease Control and Prevention, adding that it's the first such HIV vaccine to begin a second-phase clinical trial.

This vaccine under development, which contains DNA segments from HIV instead of the full human immunodeficiency virus, will have a stronger and longer-lasting effect. It is also designed to target the HIV strains that are most common in China, Shao was cited by the newspaper as saying.

More than 130 volunteers have been recruited so far, and the initial work is underway at a hospital in Beijing and another in the city of Hangzhou, he added.

"Hopefully the second-phase trial will be completed in the latter half of 2021, and the third-phase clinical trial may start at the end of that year, which will involve thousands of volunteers in a trial to test the effectiveness of the vaccine to protect people against HIV," Shao said.

Springfield, Jul 19 (AP/UNB) — An Illinois woman who recently got a 1993 postcard in her mailbox has tracked down the man who sent it to his children more than two decades ago.

Kim Draper's story about the mysterious Hong Kong postcard was published in The State Journal-Register in Springfield and picked up by The Associated Press.

Masrour Kizilbash sent the postcard to his family while working overseas in 1993. He told the newspaper that he was "fascinated with the area" and wanted to share his experiences. At that time, there were no cell phones or internet and international calls were costly, so he instead opted to send postcards.

Kizilbash's family was living in Springfield at the time. He always figured that they had received the postcard.

U.S. Postal Service officials said the card could've gotten tied up in Hong Kong or might've been stuck in old equipment.

With the help of social media, Draper learned that Kizilbash's son, Mohammad Kizilbash, now lives in suburban Chicago. A reunion with the postcard is planned.

"I thought that was really gracious of her, she went out of her way to track us down," Mohammad said. "I'm looking forward to getting this postcard. This is one to keep."

Draper would ideally like to appear with the Kizilbashes on a TV show to give them the card, but if that can't happen, she'll drive to Chicago and give it to them in person.

"I won't mail it. I don't want it to get back in the mail system, and I really want to meet them," Draper said. "I am surprised about how the story has spread," she said. "But at the same time it's heartwarming. I think it made people want to know the family and it's one of those cool stories that you want to hear the end."

Washington, Jul 19 (AP/UNB) — The Environmental Protection Agency rejected a key legal challenge Thursday to a pesticide linked to brain damage in children, saying environmental groups had failed to prove that a ban was warranted.

The agency's defense of continued use of the widely used bug-killer chlorpyrifos could set the stage for a pivotal federal court decision on whether to overrule the EPA and force the agency to ban it.

"To me, this starts the clock on the use of chlorpyrifos on food crops in the US," said former senior EPA attorney Kevin Minoli.

Scientists say studies have shown that chlorpyrifos damages the brains of fetuses and children. The pesticide has been used nationally on dozens of food crops, but California — the nation's largest agricultural state — and a handful of other states have recently moved to ban it.

The agency said the environmental groups had failed to prove that the pesticide wasn't safe.

Last summer, a three-judge panel of the 9th Circuit Court of Appeals ordered the EPA to ban all sales of the pesticide. The court decided to reconsider that ruling with a slate of 11 judges, who gave the EPA until this month to respond to the environmental groups' arguments for banning chlorpyrifos.

The EPA under the Obama administration had initiated a ban, but the agency reversed that decision shortly after President Donald Trump took office.

The EPA defense Thursday showed that "as long as the Trump administration is in charge, this EPA will favor the interests of the chemical lobby over children's safety," said Ken Cook, head of the Environmental Working Group environmental advocacy organization.

In a statement, the EPA said it was separately speeding up a regular agency review of the pesticide's continued use, and expected a decision on that well ahead of a 2022 deadline.

The EPA said it also was talking with chlorpyrifos makers about further restrictions on how farmers use the pesticide.

New York, Jul 18 (AP/UNB) — U.S. overdose deaths last year likely fell for the first time in nearly three decades, preliminary numbers suggest.

The Centers for Disease Control and Prevention on Wednesday posted data showing nearly 68,000 drug overdose deaths were reported last year. The number may go up as more investigations are completed, but the agency expects the tally will end up below 69,000.

Overdose deaths had been climbing each year since 1990, topping 70,000 in 2017.

The numbers were celebrated by the U.S. secretary of health and human services. "Lives are being saved, and we're beginning to win the fight against this crisis," Alex Azar wrote in a tweet.

But the overdose death rate is still about seven times higher than it was a generation ago.

"We're still in a pretty sad situation that we need to address," said Rebecca Haffajee, a University of Michigan researcher.

Researchers do not believe this is the start of a dramatic decline. Data from the first months of this year likely will show that the decrease is not gaining steam, said Farida Ahmad of the CDC's National Center for Health Statistics.

The improvement was driven by a drop in deaths from heroin and prescription painkillers. Those falls were offset somewhat by continuing growth in deaths involving a different opioid, fentanyl, as well as other drugs such cocaine and methamphetamines. Overdose deaths often involve more than one drug.

The improvement is not uniform: Some states seem to be making dramatic progress, while deaths continue to rise in others. The preliminary CDC data suggested deaths last year were down by as many as 1,000 or more in Ohio and Pennsylvania — each seeing declines of about 20%. Meanwhile, deaths increased by about 17% in Missouri, which had more than 200 additional deaths.

It can take months for authorities to complete toxicology tests and other elements of a death investigation involving drugs. And some states report faster than others. The CDC is expected to report more complete data later this year.

The current overdose epidemic has killed more people than any other in U.S. history, and it had been on a soaring trajectory. From 2014 to 2017, overdose deaths jumped by 5,000 or more each year.

Experts trace the epidemic's origins to 1995 and the marketing of the prescription painkiller OxyContin. It was meant be safer and more effective than other prescription opioids, but some patients got hooked and found they could crush the tablets and snort or inject them to get high.

Gradually, many turned to cheaper street drugs such as heroin and fentanyl. In 2015, heroin began causing more deaths than prescription painkillers or other drugs. In 2016, fentanyl and its close cousins became the biggest drug killer, and in 2018 they were involved in about 46% of the reported overdose deaths, according to the preliminary CDC data.

Strategies to reduce drug overdose deaths have included tougher policing, treatment program expansions, policies to limit opioid painkiller prescriptions and wider distribution of the overdose-reversing drug naloxone.

Haffajee and other researchers are trying to figure out what measures are most responsible for the slight improvement.

"It's complicated because there are so many policies going on, and as an evaluator it's very hard to separate them out and determine which is working," she said.

Valerie Hardcastle, a Northern Kentucky University administrator who oversees research and other work on local health issues, has seen the overdose epidemic play out in her region, near Cincinnati. She believes a major factor is Narcan, a nasal spray version of naloxone, that has been widely distributed through the efforts of philanthropists and local, state, and federal officials.

"It's fantastic that we have fewer deaths, don't get me wrong," she said. "But I'm not sure it's an indication that the opioid problem per se is diminishing. It's just that we have greater availability of the drugs that will keep us alive."
