Here are news highlights from the business world.
Strap on your computer, wearable tech taking off
SAN FRANCISCO - The digital domain is creeping off our desktops and onto our bodies, from music players that match your tunes to your heart beat, to mood sweaters that change color depending on your emotional state - blue for calm, red for angry. There are vacuum shoes that clean the floor while you walk and fitness bracelets, anklets and necklaces to track your calorie burning.
"Everyone agrees the race is just beginning, and I think we're going to see some very, very big leaps in just the next year," said tech entrepreneur Manish Chandra at a wearable technology conference and fashion show in San Francisco that was buzzing with hundreds of developers, engineers and designers.
Wearable technologies have long been a sideshow to mainstream laptop and smartphones, but this year Google's glasses and rumors of Apple's iWatch are popularizing the field. Analysts forecast swift growth. The market for wearable technology - encompassing everything from hearing aids to wristband pedometers - totaled almost $9 billion last year. That should climb to $30 billion by 2018, said analyst Shane Walker at IHS Global Insights.

US government shutdown closes parks, monuments
PHILADELPHIA - Visitors arrived to find "CLOSED" signs at the Statue of Liberty, the Smithsonian and other parks and historic sites across the country. Callers looking for help from the government reached only voicemail. And federal employees were left to wonder when they would return to work.
The first government shutdown in 17 years took hold in ways large and small.
About 800,000 federal employees were sent home - a number greater than the combined U.S. workforces of Target, General Motors, Exxon and Google.

Utilities, solar companies in fight over rates
ATLANTA - Sunlight is free, but if you use it to make electricity your power company wants you to pay.
Utilities in many states say solar-friendly rate plans, conceived to promote alternative energy sources, are too generous and allow solar customers to avoid paying for the grid even though they use it.
Some power companies are proposing an extra fee for solar customers. Others are trying to roll back or block programs that allow those customers to trade the solar power they generate during sunny days for power they need from the grid during other times.
As rooftop solar expands from a niche product to a mainstream way to save money on power bills, utilities are afraid they will lose so many customers - and revenue - that they won't be able to afford to build and maintain the grid.

US manufacturing expands at best pace in 2 1/2 years
WASHINGTON - U.S. factory activity expanded last month at the fastest pace in 2 1/2 years, an encouraging sign that manufacturing could lift economic growth and hiring in the coming months.
The Institute for Supply Management, a trade group of purchasing managers, said its manufacturing index rose in September to 56.2, the highest since April 2011. That's up from 55.7 in August and the fourth straight increase in the index. A reading above 50 indicates growth.
Manufacturers added jobs last month at the fastest pace in more than a year and ramped up production, the survey showed. They also received new orders at a healthy pace, though slower than in August.

Sept. US sales falter, but automakers see rebound
DETROIT - Automakers expect little impact from the federal government shutdown, and they predict a fourth-quarter rebound after a rare sales decline in September.
Auto sales dropped 4 percent from a year ago to just over 1.1 million, mainly due to a calendar quirk that pulled Labor Day weekend transactions into August's numbers. The drop ended a 27-month streak of gains for the industry.
General Motors, Honda and Volkswagen reported double-digit declines for last month. Toyota, Nissan and Hyundai posted smaller decreases. Only Ford and Chrysler reported gains among the bigger automakers.

Merck to cut 8,500 more jobs
Merck & Co. plans to cut another 8,500 jobs as the drugmaker continues its struggle with competition from cheaper generic medications that have squeezed the pharmaceutical industry for several quarters now.
The New Jersey-based company said the reductions are in addition to a total of 7,500 cuts it had previously announced but hasn't carried out. That means it is slashing about 20 percent of its workforce, currently at about 81,000 people.
Merck, the world's third-largest drugmaker, said the restructuring will cost a total of between $2.5 billion and $3 billion before taxes, mainly due to employee severance costs. But it expects the moves to help generate annual savings of about $2.5 billion by the end of 2015.
