Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis of the "5-second rule" — the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the ‘5-second rule', until now it was unclear whether it actually helped.

    The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor floor types as carpet, cement floor to toast, pasta, biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: time is a significant factor in the transfer of bacteria from a floor surface to a piece of food, and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said, "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time."

    The Aston team also carried out a survey of the number of people who employ the ‘five-second rule'. The survey showed that: 87% of the people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those that would, or have eaten food dropped on the floor are women. 81% of the women who would eat food from the floor would follow the ‘5-second rule'. Professor Hilton added, "Our study showed that a surprisingly large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the ‘5-second rule, which our research has shown to be much than an old wives' tale."

    Just a few years out of law school, I decided that I wanted to write fictions. The only thing I had ever published before was a law-review article. I had made great efforts to write when I came home at night after work, but I was too tired. I decided to quit my job.

    I began my new life on a February morning. I sat down at my kitchen table at 7:30 am and made a resolution. Every day I would write until lunchtime. Then I would lie down on the floor for 20 minutes to rest my mind. After that, I would return to work for a few more hours.

    In my first year, I sold two stories. Then I wrote a novel, but I thought it wasn't good enough, so I ended up putting it in a drawer. My second novel, Billy Lynn's Long Halftime Walk, was published to glowing reviews and received the National Book Critics Circle Award for fiction.

    My success sounds like a familiar story, but actually it was far from sudden. I quit my job, and for every story I published in those years, I had at least 30 rejections. The novel that I put away in the drawer took my four years. My breakthrough came in 2006, 18 years after I first sat down to write at my kitchen table.

    Sometimes genius (天才) is just the thing that comes out after 20 years of working at your kitchen. Also, doing something truly creative requires the energy of youth. Orson Welles made his masterpiece, Citizen Kan, at 25. T. S. Eliot wrote The Love Song of J. Afred Prufrock at 23.

    Everyone should be so lucky as to have a friend like Francia Raisa. On Thursday, singer and actress Selena Gomez, 25, used Instagram to explain why she was "laying low" this summer. She posted a photo of herself in a hospital bed with her friend Francia Raisa holding hands. She said she recently received a kidney transplant from her best friend because of complications(并发症) from lupus(狼疮), an autoimmune disease, which means it is the result of the immune system attacking normal tissue, including the kidneys, brain, heart and lungs.

    People with lupus may first experience tiredness, joint pain or a little bit of rash(皮疹) on their bodies and can go for a long time before their doctors realize it is more serious. Many people see two or four doctors before the real problem is picked up. According to Dr. Kyriakos Kirou, roughly a third to one-half of people with lupus develop kidney disease, and up to one in five of them will eventually need a transplant, sometimes because they weren't treated with effective drugs to prevent the immune system from attacking the kidneys. Though Gomez said that she was "very well now," she warned about the dangers of not taking medical diagnoses seriously, like she initially did.

    Her Instagram post also called attention to two major health topics: the need for living organ donators and the fact that Gomez represents three groups more likely to be diagnosed with lupus and lupus-related kidney disease. Nine out of 10 people diagnosed with lupus are women, and most develop the disease between the ages of 15 to 44. And lupus is two to three times more common among women of color, including Hispanic women, according to the Lupus Foundation.

    Raisa is Latina, and Gomez's father is of Mexican origin. While it's not essential that the organ donator and receiver be of the same ethnicity, people who share a similar background sometimes are better matched, according to data from the United Network for Organ Sharing.

    Shot in more than 40 locations in L.A., the musical La La Land is "a love letter to the city". To coincide with UK release, we asked a local writer to pick some of the film's amazing settings.

    Judge Harry Pregerson Interchange

    La La Land's opening scene is a six-minute dance that plays out in L.A.'s bad traffic. It is also where the film's leading roles, struggling actress Mia and jazz pianist Sebastian, first encounter each other—in a road anger incident. The scene is said to have been filmed over two hot days in south L.A.

    Smokehouse Restaurant, Burbank

This is the setting for the scene in which Mia discovers Sebastian's talent for the piano. The fictional Lipton's restaurant—where jazz purist Sebastian was reluctant to play Christmas music—is in reality a place long frequented by actors, producers and other show business types. It has been on this spot, across the street from the Warner Bros studio, since 1949. In the film, the outer wall of Lipton's is the You are the Star mural (壁画), which features Marilyn Monroe, Charlie Chaplin and others, which is on the corner of Hollywood Boulevard and Wicox Avenue in Hollywood in reality.

    Warner Bros Studios, Burbank

    Mia works at the studio's coffee shop, where Sebastian comes to meet her. As they wander the studio's lot, Mia points out "the window that Humphrey Bogart and Ingrid Bergman looked out in Casablanca." It's one of the film's numerous nods to movie history. Warner Brons is still a working studio, with 35 sound stages, 14 exterior sets and visitor tours.

    Cathy's Corner, Mount Hollywood Drive

    This section of the road that winds through Griffth Park is the setting of their dance play. It overlooks the San Fernando Valley and features on the film poster. Cathy's Corner is near famed Mulholland Drive, but prepare for disappointment if you're expecting a park bench and street lamps, which only exist in the movie.

    For the first time, the World Health Organization has included Traditional Chinese Medicine (TCM) in its globally influential medical compendium(手册), according to an international science journal.

    An article published by Nature on Wednesday said that TCM will be included in the latest version of the International Classification of Diseases (ICD)set to be released next year. Starting from the 1800s, the ICD has been improved and published in a series of editions, reflecting the advances in health and medical science over time. It serves as the foundation for the identification of global health trends, and the international standard for diseases and health conditions.

    The latest ICD is based largely on the work of the International Classification of Traditional Medicine (ICTM) project's experts from around the world. These experts had been working on traditional medicine research and practices for years.

    China has been promoting the modernization of TCM and pushing for TCM to gain acceptance worldwide. Tu Youyou, a Chinese expert focusing on the scientific study of drugs and medicines, was awarded the Nobel Prize in Medicine in 2015 for her research in TCM. Her discovery has saved millions of lives in developing countries in South Asia, Africa and South America. TCM is sure to grow in popularity globally.

    Though the application of traditional Chinese medicine, acupuncture(针灸) and other traditional medical practices has been on the rise, there's still a shortage of global classification and terminology(术语) tools for traditional medicine, according to officials of the WHO.

    "The decision is to promote the safe and effective use of traditional medicine by regulating, researching and combining traditional medicine products, practitioners and practice into health systems, where appropriate," the WHO was quoted as saying by Nature.

At a time when industries are under greater pressure to reduce costs and increase efficiencies, more production facilities are turning to digital sensing technology to provide the real-time insights they need for improved performance. What if one digital sensor could measure multiple signals?

Yokogawa's DPharp (差压传送器) digital technology has the unique ability to measure two pressure parameters (参数), delivering reliable and accurate measurement of plant operations. The unique aspect of this digital technology is that it measures two parameters in one sensor module, providing additional insight into a plant's operations. It is the only sensor in the world that does this.

DPharp transmitters (发射器) use silicon (硅) resonant (谐振的) sensor technology to measure both differential (差别) and still pressure. The sensor consists of two H-shaped crystal silicon resonators that shake at a certain frequency and, when pressure is applied, the frequency of one resonator increases while the other decreases. By monitoring these frequencies digitally, both differential and still pressure can be measured at the same time. The frequency output is directly read by the central processing unit of the transmitter.

DPharp can be used in any processing plant across any industry—oil and gas to food and drinks. DPharp's unique digital sensing technology allows engineering firms and plant engineers to create designs that will equate to an average reduction of 40 percent. Where they would typically use five measuring devices, they are using three by using the multi-sensing technology. That is a significant cost reduction in the number of devices installed and the added benefit is that, as there are less devices, the engineering and design is less complex, which means less materials and less equipment to maintain. Furthermore, there are fewer transmitter spares required, which reduces costs. Tony Farah, Product Manager, said that more organisations are seeing the significant benefits of smart devices like DPharp.
