Smart homes are here to stay. Many of us now have an Amazon Echo or Google Home and are adding video doorbells, automatic door locks and other automation features.But how can you make sure you are keeping your family safe and not sharing your most private moments with the world?Digital assistants doing more and moreIt all started with Amazon's Echo digital assistant, which in the beginning played music and answered our basic questions.Then along came Google Home, and soon we were using voice assistants to ask who's at the front door, open up the garage and adjust the lights.Now, almost two years later, digital assistants are flying off the shelves at Best Buy, loved by busy moms like Amanda Compton, who we found shopping with her toddler at a Best Buy store."It does a lot of work for you when you have kids," she said. "It kind of helps out a lot."Google vs AmazonThe first thing you'll notice when you are looking at smart home devices is that there are two different universes. You have the option of purchasing Google Home or Amazon's Echo, each selling for around 0 (though simplified models cost less.)Apple recently launched the Home Pod, though is it a bit late to the game and at 0 is much more expensive than the competition. Like the Apple Watch, it appears aimed at a more upscale audience.Each works with its own set of apps and devices, though in the end they are pretty much the same, according to Best Buy's Brian Gibson.Which is better? Gibson says its really just personal choice. All of them will control cameras, your thermostat, smart lights, even smart door locks.How vulnerable are you?But some security experts are sounding the alarm.IT security consultant David Hatter says a vulnerability in one of your devices can let a hacker watch your video cameras, maybe even access your bank account, if they are all on the same WiFi network."If someone can break into your washing machine," Hatter explained, "and then into your door lock, they can potentially break into your house or your bank account."He says many people set up smart devices leaving the default password, which is often as simple as 1-2-3-4."If you just buy a smart thermostat and don't change any of the settings, you're ripe for hacking," he said.He says Echo and Google home units themselves are fairly secure, but it is the peripherals that are more vulnerable.Hatter says to protect yourself: 2435
Sixteen of the largest wildfires burning in California have scorched 320,000 acres — an area larger than the entire city of Los Angeles.The Carr Fire, which has left six people dead and burned 121,000 acres by itself, is now considered the sixth most destructive fire in California history, according to the California Department of Forestry and Fire Protection, also known as Cal Fire.Forecasters said winds, high temperatures and low humidity don't bode well for containing the blazes.PHOTOS: Carr Fire rages in California"California can expect to see hot, dry and breezy conditions through the end of the week," CNN meteorologist Gene Norman said.Temperatures will soar into the lower 100s in many places, Norman said, and whipping winds will be "wildly fluctuating as the fires generate their own localized wind." 825
Some workers have saved a ton of money during the pandemic thanks to many not having to commute. In fact, it’s reported that the total savings by Americans not having to commute is upwards of billion.On average, workers across the country usually have a work commute of about 50 minutes.“I don’t miss the commute at all,” said Raymond Kelly, who is now working from home. "It was a little drive on both sides and a boat in the middle.”Kelly is an engineer in Washington state, and for eight years, his commute was far longer than the average workers’.Every day, he commuted from Poulsbo, Washington to Muckilteo. First, he drove 30 minutes to park and catch a ferry in Kingston, Washington. After the 30 minutes ferry ride, he got into his second car parked on that side of the Puget Sound and then drove another 30 minutes to finally get to his job. In total, his commute was about three to four hours a day. However, since his company began allowing people to work from home in March, his commute is now just two or three minutes. It’s the walk from his bed to a small office he created in his home.“I think it has been huge. It is almost like getting a piece of life back,” said Kelly.Kelly is saving at least 0 a month not commuting to work, and most Americans are seeing a similar savings. A survey done by a company called Upwork shows the average American has saved about ,000 since March by also not commuting to work.“The total savings since March comes out to billion,” said Adam Ozimek, the chief economist at Upwork.“In the long run, the money you save on this is the money you spend elsewhere,” added Ozimek. "What we know from the survey is it consumers are generally spending more online. They are spending more at grocery stores. They are spending more those way and also are saving more."A new poll by the National Opinion Research Center shows 45 percent of Americans are putting the money saved on commuting into their personal savings, while 26 percent are paying down debt at a faster rate than Americans did pre-pandemic.Long term, as more employers signal remote work as a more permanent way to work, economists believe the money saved commuting will be put towards things like people eating out more and traveling. Both would help struggling sectors of the economy and industries struggling the most right now.As for Kelly, he’s been spending his commute savings on home-improvement projects. 2437
Senate Majority Leader Mitch McConnell said Thursday he is not sending senators home until there is a coronavirus stimulus bill that has been approved by the chamber.“The Senate is not going anywhere until we have COVID relief out the door. We're staying right here until COVID relief is out the door,” McConnell said.As far as the status of negotiations?“Conversations are still underway and making progress on the major pandemic relief package we've all been seeking for the American people. As I've been saying, families across the nation have waited far too long already for another significant dose of assistance. We must not slide into treating these talks like routine negotiations to be conducted at Congress' routine pace,” McConnell said.McConnell’s view is one shared by Minority Leader Chuck Schumer.“We have a responsibility to get this right. People's lives depend upon it,” he said.Last week, House Speaker Nancy Pelosi said that the House will not break for the holidays until pandemic relief is passed.There is added pressure on Congress as the government runs out of funding Friday night.But both sides have been working on economic relief for months, but have failed to come to any sort of compromise.Two weeks ago, a bipartisan group of legislators proposed a 0 billion stimulus plan that would extend funds for additional unemployment benefits for up to 18 weeks per worker. The legislation also would replenish funds for the Paycheck Protection Program, which helped companies affected by the pandemic make payroll.In recent days, members of Congress have pushed for 0 stimulus checks to be added to the comprehensive package. The checks would be sent to Americans in a similar fashion as the stimulus checks most Americans received in the spring. 1783
Smoke masks. Eye drops. No outdoor exercise. This is how Californians are trying to cope with wildfires choking the state, but experts say an increase in serious health problems may be almost inevitable for vulnerable residents as the disasters become more commonplace.Research suggests children, the elderly and those with existing health problems are most at risk.Short-term exposure to wildfire smoke can worsen existing asthma and lung disease, leading to emergency room treatment or hospitalization, studies have shown.Increases in doctor visits or hospital treatment for respiratory infections, bronchitis and pneumonia in otherwise healthy people also have been found during and after wildfires.RELATED: Missing-persons list tops 600 in Camp FireSome studies also have found increases in ER visits for heart attacks and strokes in people with existing heart disease on heavy smoke days during previous California wildfires, echoing research on potential risks from urban air pollution.For most healthy people, exposure to wildfire smoke is just an annoyance, causing burning eyes, scratchy throats or chest discomfort that all disappear when the smoke clears.But doctors, scientists and public health officials are concerned that the changing face of wildfires will pose a much broader health hazard."Wildfire season used to be June to late September. Now it seems to be happening all year round. We need to be adapting to that," Dr. Wayne Cascio, a U.S. Environmental Protection Agency cardiologist, said this week.In an overview published earlier this year, Cascio wrote that the increasing frequency of large wildland fires, urban expansion into wooded areas and an aging population are all increasing the number of people at risk for health problems from fires.Wood smoke contains some of the same toxic chemicals as urban air pollution, along with tiny particles of vapor and soot 30 times thinner than a human hair. These can infiltrate the bloodstream, potentially causing inflammation and blood vessel damage even in healthy people, research on urban air pollution has shown. Studies have linked heart attacks and cancer with long-term exposure to air pollution.Whether exposure to wildfire smoke carries the same risks is uncertain, and determining harm from smog versus wildfire smoke can be tricky, especially with wind-swept California wildfires spreading thick smoke hundreds of miles away into smoggy big cities."That is the big question," said Dr. John Balmes, a University of California, San Francisco, professor of medicine who studies air pollution."Very little is known about the long-term effects of wildfire smoke because it's hard to study populations years after a wildfire," Balmes said.Decreased lung function has been found in healthy firefighters during fire season. They tend to recover but federal legislation signed this year will establish a U.S. registry tracking firefighters and potential risks for various cancers, including lung cancer. Some previous studies suggested a risk.Balmes noted that increased lung cancer rates have been found in women in developing countries who spend every day cooking over wood fires.That kind of extreme exposure doesn't typically happen with wildfires, but experts worry about the kinds of health damage that may emerge for firefighters and residents with these blazes occurring so often.Whether that includes more cancer is unknown. "We're concerned about that," Balmes said.Regular folks breathing in all that smoke worry about the risks too.Smoke from the fire that decimated the Northern California city of Paradise darkened skies this week in San Francisco, nearly 200 miles southwest, and the air smelled "like you were camping," said Michael Northover, a contractor.He and his 14-year-old son have first-time sinus infections that Northover blames on the smoke."We're all kind of feeling it," Northover said.The smoke was so thick in San Francisco, the skyline was barely visible from across the Bay. The city's iconic open-air cable cars that are popular with tourists were pulled off the streets Thursday because of the bad air.An Environmental Protection Agency website said air quality in Sacramento was "hazardous" Thursday and San Francisco's was "very unhealthy." Many people walking around the cities wore face masks.Most schools in San Francisco, Sacramento, Oakland and Folsom said they would be closed Friday. At least six universities in Northern California canceled classes Thursday.At Chico State University, 11 miles (18 kilometers) from Paradise, ash fell this week and classes were canceled until after Thanksgiving."It's kind of freaky to see your whole town wearing air masks and trying to get out of smoke," said freshman Mason West, 18. "You can see the particles. Obviously, it's probably not good to be breathing that stuff in."West returned home this week to Santa Rosa, hard hit by last year's wine country fires, only to find it shrouded in smoke from the Paradise fire 100 miles (160 kilometers) away. West's family had to evacuate last year for a week, but their home was spared."It's as bad here as it was in Chico," West said. "It almost feels like you just can't get away from it."Smoke has been so thick in Santa Rosa that researchers postponed a door-to-door survey there for a study of health effects of last year's fire."We didn't feel we could justify our volunteer interns going knocking on doors when all the air quality alerts were saying stay indoors," said Irva Hertz-Picciotto, a public health researcher at the University of California, Davis. The study includes an online survey of households affected by last year's fire, with responses from about 6,000 people so far.Preliminary data show widespread respiratory problems, eye irritations, anxiety, depression and sleep problems around the time of the fire and months later."Conventional thinking is that these effects related to fires are transient. It's not entirely clear that's the case," Hertz-Picciotto said.Researchers also will be analyzing cord blood and placentas collected from a few dozen women who were pregnant during the fire, seeking evidence of stress markers or exposure to smoke chemicals.They hope to continue the study for years, seeking evidence of long-term physical and emotional harms to fire evacuees and their children.Other studies have linked emotional stress in pregnant women to developmental problems in their children and "this was quite a stress," Hertz-Picciotto said.It's a kind of stress that many people need to prepare for as the climate warms and wildfires proliferate, she said."Any of us could wake up tomorrow and lose everything we own," she said. "It's pretty scary."___Follow AP Medical Writer Lindsey Tanner at https://twitter.com/LindseyTanner .
