> Hurricane Fiona rips through powerless Puerto Rico


Hurricane Fiona struck Puerto Rico’s southwest coast on Sunday as it unleashed landslides, knocked the power grid out, and ripped up asphalt from roads and flung the pieces around.

Hundreds of people were evacuated or rescued across the island as floodwaters rose swiftly.

Rushing rivers of brown water enveloped cars, first floors and even an airport runway in the island’s southern region. “The damages that we are seeing are catastrophic,” said Gov. Pedro Pierluisi.

>US mortgage rates hit 14-year high as inflation soars
美国按揭利率创下14年新高 购房成本大增



The average interest rate on a 30-year mortgage hit 6.02% last week, more than double what it was a year ago.

For families hoping to buy a home, the moves compound affordability problems.

The rise comes as the US central bank aggressively raises rates in an effort to reduce the pressures driving up inflation across the economy.

US consumer prices rose by 8.3% in the year to August, the fastest rate in almost 40 years, the Labor Department said last week.

Mortgage rates have spiked in anticipation of the moves.

"Rates continued to rise alongside hotter-than-expected inflation numbers this week, exceeding 6% for the first time since late 2008," said Sam Khater, chief economist at Freddie Mac, the government-sponsored mortgage firm that released the interest rate data.


> Daily steps to cut risk of dementia
研究:走路可预防痴呆症 步速比步数更重要



Want to reduce your risk of dementia?

Slap on a step counter and start tallying your steps -- you'll need between 3,800 and 9,800 each day to reduce your risk of mental decline, according to a new study.

People between age 40 and 79 who took 9,826 steps per day were 50% less likely to develop dementia within seven years, the study found.

Furthermore, people who walked with "purpose" -- at a pace of over 40 steps a minute -- were able to cut their risk of dementia by 57% with just 6,315 steps a day.

Another editorial published in the JAMA Neurology journal argued that individuals looking to reduce their risk of dementia focus on their walking pace over their distance.

The largest reduction in dementia risk -- 62% -- was achieved by people who walked at a very brisk pace of 112 steps per minute for 30 minutes a day, the study found.


> Bird flu endangers penguin colony in South Africa



Four cases of avian flu, or bird flu, were confirmed among endangered penguins at Boulders Penguin Colony in Cape Town, a local news website reported, citing a clinical veterinarian.

As of Sept 16, there had been four confirmed cases and another seven suspected cases, said Table Mountain National Park (TMNP) management.

Once seabirds show symptoms of bird flu, they usually die soon afterward, News24 reported, quoting Dr David Roberts, a clinical veterinarian at the Southern African Foundation for the Conservation of Coastal Birds.

Now, conservationists worry the same fate could await the endangered penguins, if no quick action is taken.

Roberts said that it could also pose a significant risk to breeding colonies if there is an outbreak in endangered species, like the African Penguin, Cape Cormorant and Cape Gannet.
