【推荐1】Planning a visit to the UK? Here we help with ways to cut your costs.
AVOID BIG EVENTS Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy Festival (19 Oct.) cost £169.15 at Booking.com. A week later, the same room cost £l18.15.
If you can be flexible and want to know dates to avoid-or you’re looking for a big event to pass your time—check out sites such as Whatsonwhen.com, which allow you to search for events in the UK by city, date and category.
STAY AWAY FROM THE STATION If traveling to your destination by train, you may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday.
Don’t be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge’s Central Euston hotel in London for Saturday 22 September was £95.95. A room just a tube journey away at its Covent Garden hotel was £75.75. And at Farringdon, a double room cost just £62.95.
GET ON A BIKE London’s ‘Boris bikes’ have attracted the most attention but other cities also have similar programmes that let you rent a bicycle and explore at your own pace, saving you on public transport or car parking costs.
Among the smaller cities with their own programmes are Newcastle (casual members pay around £1.50 for two hours) and Cardiff (free for up to 30 minutes, or £5 per day).

【推荐3】Floods
Basic safety Tips
● Turn around and don’t drown!
● Avoid walking or driving through flood waters.
● If there is a chance of flash floods, try to move to a higher place. Flash floods are the No. 1 cause of weather-related deaths.
If floodwaters rise around your car but the water is not moving, give up the car and move to higher ground. Do not leave the car enter moving water.
Avoid camping or parking along streams, rivers during heavy rainfall. These areas can flood quickly with little warning.
Flood Watch
Steps to Take
● Turn on your TV/radio. You will receive the latest weather forecast and emergency instructions.
● Know where to go. You may need to reach higher ground quickly.
● Build or fill your emergency kit with something new. Include a flashlight, batteries, cash, and
first-aid supplies.
● Bring in outdoor, furniture and move important indoor items to the highest possible floor. This is help protect them from flood damage.

【推荐1】Since 50 years ago, scientists have been searching for ways to link the brain with computers. Brain Computer Interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michelle Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person’s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says, “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.” He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

【推荐2】Amazon is opening its 12th high-tech convenience store Tuesday in New York. The spot will be the first of the chain to allow customers to pay with cash. The move comes with growing resistance against cashless stores, which critics say refuse to serve people who don’t have bank accounts.
At other locations of the store, shoppers enter by scanning the Amazon Go app. That's still the case for customers paying with a credit card, but people paying with cash will have an “entry associate” scan them through the turnstiles (旋转栅门). Once they’re finished, those shoppers will check out with an Amazon Go employee and receive a paper receipt. Cashless customers can still walk out by scanning a phone that has the Amazon Go app at the turnstiles. Customers using the Go app can exit without waiting and get a digitized receipt.
The 1,300-square-foot New York store-the first Amazon Go store on the East Coast-will offer prepared foods, such as sandwiches and salads, It will also have Amazon Meal Kits and locally made options.
Amazon says it will begin accepting cash at its other Go stores “over time.” A number of retailers (零售商) and restaurants, such as Sweetgreen and Dos Toros Taqueria, are facing roadblocks to their cashless recommendations.
New Jersey Governor Phil Murphy recently signed a law banning cashless stores in that state. Philadelphia also passed a law to prohibit cashless stores earlier this month, and officials in New York City, Washington and San Francisco are considering similar moves. The federal government does not require retailers to accept cash.
“While card-only may be convenient for some businesses, it can actually be discriminatory against poor communities that don’t have as much access to banks or lines of credit,” said New Jersey State Senator Nellie Pou, who sponsored the state’s new law. Not accepting cash could also be bad for business. Americans use it in 30% of all business deals, according to a 2017 report from the Federal Reserve Bank of San Francisco.

【推荐3】PhoneSoap: Charge and Clean Your Phone
You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won’t surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them—specifically, the bacteria called E. coli.
The research on bacteria and viruses led to the invention of PhoneSoap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges.
“There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones,” says Wes Barnes, the PhoneSoap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. “He realized he got the idea of getting rid of bacteria and viruses on the phones,” said Barnes. “In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines.”
PhoneSoap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you’d plug it into the PhoneSoap charger box. The process only takes a few minutes but, Barnes says, “The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully.”
The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week’s International Consumer Electronics Show in Las Vegas, PhoneSoap was all grown-up. Both co-founders have left their previous jobs and are selling PhoneSoap nonstop. “We’re shipping almost more than we can handle each day,” Barnes says. “It’s been a great adventure.”

【推荐3】You’ re in your car, heading for a crossroads. The light turns yellow, so you decide to step on the gas. Then you see a police car. Almost instantly, you know that stepping on the accelerator (油门) is a mistake. But there’s a good chance that you’ll do it anyway, says Susan Courtney, a professor in the Department of Psychological& Brain Sciences at Johns Hopkins University.
Thar’s because as one area of your brain is recognizing that police car, other areas have already begun carrying out your original plan to speed up. "Even if you haven’t actually started moving your your brain has already started that plan, Courtney says. And stopping a plan requires a lot of brainpower, Courtney and a team of researchers report in the journal Neuron
The team monitored the brain activity of 21 people as they met with a situation that was a bit like approaching a crossroads when the night turns yellow. Participants were asked to focus on a central point on a screen and wait for a target to appear somewhere else. Sometimes they were allowed to do the natural thing and shift their gaze to the target when it appeared. However, most of the time, they got a visual order to resist the wish to move their gaze. In other words, they had to cancel an action the brain was already planning to carry out.
The study found that changing an action required three key brain areas to communicate with eight other areas. Previous research had suggested fewer areas were required. The team also found that all the communication had to occur when participants got the order not to move their eyes.
This lag (落后) is why we experience that awful moment when our brain knows we shouldn’t step on the accelerator, but our foot does it anyway. "If the signal has already been sent, you can only watch it happen without being able to stop it, "Courtney says. The brain’s stop system appears to be involved in a lot more than just controlling our bodies. "It’s not just about stopping your foot or your eyes;it’s about changing your plan, "Courtney says.
