【推荐1】Doctors in hospital emergency rooms often see accidental poisonings (中毒). A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a chemical product meant to kill insects. These are common causes of accidental poisoning.

In cases like this, look for medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it.

In the past, some people forced poisoning victims to empty the stomach. They used a liquid, syrup of ipecac (催呕剂), to do this. But an organization of children's doctors no longer advises parents to keep syrup of ipecac. The American Academy of Pediatrics says some poisons can cause additional damage when they come back up the throat.

Millions of people know a way to save a person who is choking on something trapped in the throat. The method is commonly known as the Heimlich Maneuver or abdominal thrusts. The American Red. Cross says a rescuer should first hit the person on the back five times between the shoulder bones. These bac blows may es the choking. If the airway is still blocked, he Red Cross suggests pushing hard five times along he victim’s abdomen. The abdomen is the areas between the chest and the hip (骨)bones.

【推荐2】Researchers found brushing your teeth three or more times per day is linked with lower risk of heart failure and atrial fibrillation (心室颤动) —a heart condition that causes an irregular and often abnormally fast heart rate.

One possible theory behind the discovery is that frequent tooth brushing reduces bacteria living in the pocket between the teeth and gums, preventing them from entering the bloodstream. Existing studies show poor oral hygiene (口腔卫生) leads to bacteria in the blood, causing inflammation (炎症) in the body. Inflammation increases the risks of irregular heartbeat and heart failure, where the heart’s ability to pump blood or relax and fill with blood is weakened.

In their new research, scientists in South Korea examined the connection between oral hygiene and happening of these two conditions in a series of studies of more than 161, 000 participants aged between 40 and 79.

Participants underwent a routine medical examination between 2015 and 2016 and information was collected on height, weight, laboratory tests, illnesses, lifestyle, oral health, and oral hygiene behaviors. During a follow-up of ten and a half years on average, three percent of participants developed atrial fibrillation and around five percent developed heart failure.

The lead investigator of the new study is Tae-Jin Song, a doctor and professor at Mokdong Hospital at Ewha Woman’s University in Seoul, South Korea. He said, “We studied a large group over a long period, which adds strength to our findings.” But he also noted that the analysis was limited to one country and as an observational study it does not prove causation (因果关系).

An accompanying editorial states: “It is certainly too early to recommend tooth brushing for the prevention of atrial fibrillation and congestive (充血的) heart failure. While the role of inflammation in the happening of heart and blood vessels’ disease is becoming more and more evident, further studies are needed to explain strategies of public health importance.”

【推荐1】Students who date (约会）in middle school have significantly worse study skills, are four times more likely to drop out of school and report twice as much alcohol and tobacco use than their single classmates, according to new research from the University             of Georgia.
"Romantic relationships are a trademark of adolescence，but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas，study author and professor in the College of Public Health and head of             the Department of Health Promotion and Behavior.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.
Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires (调查表）about the students* academic             efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased             the frequency of dating in high school.
"At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,'¹ according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters.
"Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "when the couple break up. they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable             to think this could be linked to depression and divert (转移）attention from studying.”
^4tDating should not be considered a ceremony of growth in middle school，”Orpinas concluded.

【推荐2】Technology is changing the way we get our news. Many people get a lot of their news on electronic devices instead of traditional media. They turn to social media for information. Recently, China's news agency Xinhua launched computer-created news readers, the world's first artificial intelligence, or Al news presenters.

I he news readers - created by machine learning technology - are based on two real-life Chinese newsmen. One is able to present newscasts in English; the other, in Mandarin Chinese. Machine teaming was used to examine video images and sounds of the two newsmen. The system then created the Al robotic presenters, which look and sound like real people.

The AI presenters will be a great improvement to the news team because they can work 24 hours a day on its website and on social media. One of the presenters even promised to work tirelessly to keep people informed The Al newsmen were able to read the news as naturally as a human presenter

Some machine learning experts said the system showed off China's latest progress in voice recognition, text-to-speech technology and data analysis. But several experts suggested that the term Al does not correctly describe abilities of the robotic news readers. On social media, many Chinese noted that the Al presenters did not seem real. People criticized them for not being more lifelike. On Weibo, several users wrote that the news readers have no soul.

Some people argued that only low-level jobs requiring heavy labor will he easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines,

A writer for the MIT Technology Review declared Xinhua's news reader announcement as fake news. China's news presenter isn't intelligent at all. the report said. MIT Technology Review said the presenter itself is little more than a digital puppet that reads. It added. “The 'AI' in this case is the software that learns what makes a convincing-looking face and voice." While the demonstration was clearly evidence of improved technology it was a very narrow example of machine learning, the report said. Some businesses have experimented with similar technology for possible use in news operations.

【推荐3】A culture guide named Persephone welcomes travellers to Greece and takes them through a famous cave in the north. The guide moves smoothly around the underground area and can talk about it in 33 languages. It can also answer 33 questions, but only in the Greek language.

Persephone is intelligent and it is a human-sized robot. The robot has been in operation for about a month at the Alistrati Cave. Persephone guides visitors through the first 150 metres of the cave that is open to the public. For the remaining 750 metres, a human guide takes over.

The idea of creating the robot guide was put forward by Nikos Kartalis, who is the scientific director at the Alistrati site. He had this idea when he saw one on television guiding visitors at an art show. Persephone was built by the National Technology and Research Foundation and cost about 139,000 dollars. “People who had visited in the past are coming back to see the robot guide,” said Nikos. “Many foreign visitors couldn’t believe Greece had the ability to build a robot and use it as a guide in the cave.”

The robot, with a white body, black head, and two bright eyes, moves on wheels. It guides visitors to the first three of eight stops along the walkway. It can do two more stops, but it is too slow for the tour. Persephone’s creators are considering ways to increase her speed. The robot begins the tour by saying, “My name is Persephone. I welcome you to the Alistrati Cave. ”

Evdokia Karafera is a human guide who partners with Persephone. “It is helpful, because it speaks many languages,” she said. “There’s just a little delay in the touring. Most find it fascinating, especially the children, and find it interesting that it speaks many languages. Robots, at some point in the future, will take over many jobs. But I believe they cannot take the place of humans everywhere.”
