    By trying to tickle(挠痒痒) rats and recording how their nerve cells respond, Shimpei Ishiyama and his adviser are discovering a mystery that has puzzled thinkers since Aristotle expected that humans, given their thin skin and unique ability to laugh, were the only ticklish animals.

    It turns out that Aristotle was wrong. In their study published on Thursday, Ishiyama and his adviser Michael Brecht found that rats squeaked and jumped with pleasure when tickled on their backs and bellies. These signs of joy changed according to their moods. And for the first time, they discovered a special group of nerve cells. These nerve cells made this feeling so powerful that it causes an individual being tickled to lose control.

    To make sure that he had indeed found a place in the brain where tickling was processed, Ishiyama then stimulated that area with electrical currents. The rats began to jump like rabbits and sing like birds.

    “It's truly ground-breaking,” said Jeffrey Burgdorf, a neuroscientist at Northwestern University who reviewed the paper. “It takes the study of emotion to a new level.”

    Burgdorf has played a central role in our understanding of animal tickling. He was part of a team that first noticed, in the late 1990s, that rats made special noises when they were experiencing social pleasure. Others had already noted that rats repeatedly made short and high sounds during meals. But the lab where Burgdorf worked noticed that they emitted similar sounds while playing. And so one day, the senior scientist in the lab said, “Let's go and tickle some rats.” They quickly found that those cries of pleasure doubled.

    “The authors have been very adventurous,” said Daniel O'Connor, a neuroscientist at Johns Hopkins University who studies touch. To him, that finding was very surprising.

    “Why does the world literally feel different when you are stressed out?” he said. “This is the first step towards answering that question. It gives us a way to approach it with experimental rigor(严谨).”

    A qualified doctor who rarely practiced but instead devoted his life to writing.He once said: “Medicine is my lawful wife, and literature is my lover.” Russian writer Anton Pavlovich Chekhov, was a great playwright and one of the masters of the modern short story.

    When Chekhov entered the Moscow University Medical School in 1879, he started to publish hundreds of comic short stories to support his family.After he graduated, he wrote regularly for a local daily newspaper.

    As a writer he was extremely fast, often producing a short story in an hour or less.Chekhov's medical and science experience can be seen through the indifference (冷漠) many of his characters show to tragic events.In 1892, he became a full time writer and published some of his most memorable stories.

    Chekhov often wrote about the sufferings of life in small town Russia.Tragic events control his characters who are filled with feelings of hopelessness and despair.

    It is often said that nothing happens in Chekhov's stories and plays.He made up for this with his exciting technique for developing drama within his characters.Chekhov's work combined the calm attitude of a scientist and doctor with the sensitivity(敏感) of an artist.

    Some of Chekhov's works were translated into Chinese as early as the 1940s.One of his famous stories, The Man in a Shell, about a school teacher's extraordinarily orderly life, was selected as a text for Chinese senior students.

    China will green light Internet medical services conducted by medical institutions as part of a broader push to promote Internet Plus Healthcare, those at a State Council executive meeting chaired by Premier Li Keqiang decided.

    Medical institutions will be allowed to provide online diagnostic services for some common and chronic diseases in patients' follow-up visits to their doctors. The top levels of hospitals will be encouraged to provide online services, including consultations (会诊), reservations and test result inquiries.

    As China joins the ranks of middle-income countries, the demand for health services has increased accordingly. Internet Plus Healthcare can help reduce the problem of inaccessible and expensive public health services that have long been a big concern for the general public.

    One decision coming out of the meeting says the intelligent review for health insurance will be applied and the one-stop settlement will be advanced. The real-time sharing of prescription and drug retail sales will be explored, as well.

    “We must waste no time in pushing forward the measures once the decisions made.” Li said. “In recent years, top-level hospitals in major cities have seen steady increases in the number of patents. Medical bills have become a heavy burden on families and high-end medical resources sill fall short of meeting the growing demand of the public.”

    To solve the problem, a two-pronged (双管齐下的) approach must be taken. One is to establish medical partnerships to strengthen cooperation between major hospitals and community clinics. The other is to bring forward Internet Plus Healthcare to promote the sharing of quality medical resources.

    The government will see to it that long-distance healthcare services cover all county-level hospitals. So more efforts will be made to ensure that high-speed broadband network will be extended to cover medical institutions in urban and rural areas. Dedicated internet access services will be set up to meet the needs for long-distance healthcare services.

    The search engine Google celebrated on Thursday the 110th birthday of the first Native American woman engineer. Google honored Mary Ross with a special Google Doodle on its homepage.

    Ross was born on August 9, 1908, in the state of Oklahoma. She was the great-granddaughter of John Ross, the longest—serving chief of the Cherokee Nation. Her work is considered important to the early stages of the age of space travel.

    Ross showed special abilities in math and science from an early age. As a student, she developed an interest in aviation, or the practice of flying aircraft. She went on to earn a master's degree in mathematics from Colorado State Teachers College, now called the University of Northern Colorado.

    During World War II, Ross began working for the Lockheed Aircraft Corporation as a mathematician. She earned a special certification in the field from the University of California in1949.Ross was later chosen to join Lockheed's top—secret Skunk Works team that worked on aircraft designs. The name refers to a group that is permitted to work independently on advanced projects. She was the only female engineer among the team's 40 members.

    Early on, she researched defense systems. By the late 1950s, her work centered on satellites and a series of space rockets called Agenda. The rockets were extremely important in the 1960s during the Apollo moon program.

    Ross also helped develop early design ideas for space travel between planets, including flyby space flights to study Venus and Mars. Ross retired from Lockheed in 1973.But she continued to give talks at high schools and colleges to encourage more women and Native Americans to study engineering. She died in 2008, a few months before her 100th birthday.

    Many celebrated Ross' life on social media. Twitter user Aaron Perez, for example, wrote: “Mary Ross was an engineer who pioneered in the field of satellites. I never would have known if it wasn't for the doodle. Women engineers deserve more recognition.”

Photographic self-portraits have existed for as long as cameras have been in human hands. But what about selfies in space? On Twitter last year, NASA astronaut Edwin Aldrin, who famously became the second man to walk on the moon in July 1969, laid claim to a spaceflight first: taking the first selfie in space during the Gemini XII mission in 1966.

"For me, it needs to be digital to be selfie," argues Jennifer Levasseur, a director at the Smithsonian National Air and Space Museum. According to Levasseur, the concept of a selfie is directly linked to internet culture. "The thing that makes a selfie is sharing it," she says.

Still, astronauts have been carrying cameras aboard space vehicles since the 1960s. In 1966, Aldrin used a Hasselblad camera designed specifically for space. Hasselblad also painted the first camera in space a matte(磨砂) black to reduce reflections in the orbiter window. But cameras used in space need to survive extreme conditions, like temperature swings from -149° to 248°F, so Hasselblad painted later model silver.

Astronauts visiting the moon then had to take out the film and leave their camera bodies behind when they returned to Earth, because early space missions were limited by a weight limit on the returned trip. Then a big change in space camera technology came after the space shuttle Columbia broke apart on its return to Earth in 2003, Levasseur notes. "Fear that they'd never be able to bring film back from space and lose all that hard work accelerated the push for digital," she says.

Today, astronauts also have access to internet and social platforms in space and can post true space selfies made using digital cameras. Similarly, space robots are participating in selfie culture, capturing remote pictures of themselves in space or on other planets and sending them back to Earth.
