WHO concerned over increasing antibiotic resistance in human infections

GENEVA, Dec. 9 (Xinhua) -- High levels of antibiotic resistance in bacteria are causing life-threatening bloodstream infections, according to the latest report released by the World Health Organization (WHO) on Friday.For the first time, the Global Antimicrobial Resistance and Use Surveillance System (GLASS) report provides analyses of antimicrobial resistance (AMR) rates in national testing coverage, AMR trends since 2017, and data on antimicrobial consumption in humans in 27 countries.The report shows over 50 percent resistance in bacteria, which frequently causes bloodstream infections that require treatment with last-resort antibiotics. Meanwhile, common bacterial infections are becoming increasingly resistant to treatments. Over 60 percent of Neisseria gonorrhoea isolates, a common sexually transmitted disease, have shown resistance to the common oral antibacterial ciprofloxacin.WHOs Essential Medicines List (EML) divides antibiotics into three categories: access, watch and reserve. Medicines in the access group are available at all times as treatments for a wide range of common infections; the watch group lists antibiotics that are recommended as first or second choice treatments for a small number of infections, while the reserve group is for antibiotics which should only be used as a last resort in the most severe circumstances.The report shows that bloodstream infections due to resistant E. coli, Salmonella and gonorrhoea increased by at least 15 percent compared to 2017. More research is required to identify how this is related to increased hospitalizations and antibiotic treatments during the COVID-19 pandemic, the WHO says.Also, countries with lower rates of testing, mostly low- and middle-income countries, are more likely to report significantly higher AMR rates."Antimicrobial resistance undermines modern medicine and puts millions of lives at risk," said WHO Director-General Tedros Adhanom Ghebreyesus. "To truly understand the exten...

EU court: Google must delete inaccurate search info if asked

In this photo taken on Oct. 5, 2015 a woman walks by the entrance to the European Court of Justice in Luxembourg. (Photo: AP)Google has to delete search results about people in Europe if they can prove that the information is clearly wrong, the European Unions top court said Thursday.The European Court of Justice ruled that search engines must “dereference information" if the person making the request can demonstrate that the material is “manifestly inaccurate."People in Europe have the right to ask Google and other search engines to delete links to outdated or embarrassing information about themselves, even if it is true, under a principle known as “right to be forgotten."Strict data protection rules in the 27-nation bloc give people the right to control what appears when their name is searched online, but the regulations frequently pit data privacy concerns against the public’s right to know.Google said it welcomed the decision.“Since 2014, we’ve worked hard to implement the right to be forgotten in Europe, and to strike a sensible balance between people’s rights of access to information and privacy,” the company said in a statement.The case stems from a complaint filed in Germanys highest court by two managers at a group of investment companies who asked Google to remove search results based on their names that linked to articles criticizing the group’s investment model.They said the articles made false claims. Neither the managers nor the company were identified.The pair also asked Google to remove thumbnail photos of them that came up in image searches without any context.Google refused because it didnt know whether the articles were accurate or not, according to a press summary of the ruling.The court disagreed, saying that if someone submits relevant and sufficient evidence proving the “manifest inaccuracy" of the information, the search engine must grant the request.The judges said the right to freedom of expression and inf...

China launches new remote sensing satellite

Photo provided to Peoples DailyTAIYUAN, Dec. 9 (Xinhua) -- China sent a new remote sensing satellite into space from the Taiyuan Satellite Launch Center in north Chinas Shanxi Province at 2:31 a.m. Friday.The satellite, named Gaofen-5 01A, was launched aboard a Long March-2D rocket and entered its planned orbit successfully.It is a hyperspectral satellite that will be used for remote sensing and applications in diverse fields, such as pollution reduction, environmental monitoring, natural resource surveys, and climate change studies.The satellite will help improve the countrys hyperspectral observation capacity in areas such as environmental protection, land, weather, agriculture, and disaster alleviation.The satellite, sent to an orbit 705 kilometers above Earth, carries payloads such as a visible-short-wave infrared hyperspectral camera and a wide-range thermal infrared imaging device, which will provide data support for China to actively respond to global climate change, according to the China National Space Administration (CNSA).The satellite is an important part of Chinas Gaofen project, and will further improve the self-sufficiency rate of hyperspectral satellite remote sensing data in China, said the CNSA.Fridays successful launch marked the completion of the space-segment construction of Chinas Gaofen project.Launched in 2010, the Gaofen project has become the backbone network of Chinas high-resolution Earth observation system. It has promoted the construction of a national space infrastructure system integrating satellite communication, satellite remote sensing and satellite navigation.The launch was the 453rd flight mission involving use of the Long March carrier rocket series.

Oldest DNA reveals life in Greenland 2 million years ago

This illustration provided by researchers depicts Kap Kobenhavn, Greenland, two million years ago, when the temperature was significantly warmer than northernmost Greenland today. Scientists have analyzed 2-million-year-old DNA extracted from dirt samples in the area, revealing an ancient ecosystem unlike anything seen on Earth today, including traces of mastodons and horseshoe crabs roaming the Arctic. (Photo: AP)Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. Today, its a barren Arctic desert, but back then it was a lush landscape of trees and vegetation with an array of animals, even the now extinct mastodon."The study opens the door into a past that has basically been lost," said lead author Kurt Kjær, a geologist and glacier expert at the University of Copenhagen.With animal fossils hard to come by, the researchers extracted environmental DNA, also known as eDNA, from soil samples. This is the genetic material that organisms shed into their surroundings — for example, through hair, waste, spit or decomposing carcasses.Studying really old DNA can be a challenge because the genetic material breaks down over time, leaving scientists with only tiny fragments.But with the latest technology, researchers were able to get genetic information out of the small, damaged bits of DNA, explained senior author Eske Willerslev, a geneticist at the University of Cambridge. In their study, published Wednesday in the journal Nature, they compared the DNA to that of different species, looking for matches.The samples came from a sediment deposit called the Kap København formation in Peary Land. Today, the area is a polar desert, Kjær said.But millions of years ago, this region was undergoing a period of intense climate change that sent temperatures up, Willerslev said. Sediment likely built up for tens of thousands of years at the site before the climate cooled and cemented the ...

Two Chinese achievements among top 10 breakthroughs of 2022 in physics

BEIJING, Dec. 8 (Xinhua) -- Two achievements by Chinese scientists have been ranked among the top 10 physics breakthroughs of the year for 2022, which are selected by a panel of editors of Physics World, a journal in physics and interdisciplinary science.Photo: CFPThe three-atom ultracold gas created by the researchers led by Pan Jianwei, a professor from the University of Science and Technology of China, has been awarded a spot in the top 10, according to the results announced by the science publisher on Thursday.Pans group made a dense, ultracold gas of triple-atomic molecules, achieving an experimental milestone that offers multiple research opportunities for quantum chemistry.Their work, along with a similar effort from Harvard University, has paved the way for new research "in both physics and chemistry, with studies of ultracold chemical reactions, novel forms of quantum simulation, and tests of fundamental science, all closer to being realized thanks to these multi-atom molecular platforms," said the editors.Liu Xinfengs team from the National Center for Nanoscience and Technology in Beijing proposed a new material for next-generation semiconductors. Their findings have also been rewarded with a spot in the annual top 10 rankings.Liu and researchers from the University of Houston confirmed that cubic boron arsenide is one of the best semiconductors known to science.They revealed that small and pure regions of this material have a much higher thermal conductivity and hole mobility than semiconductors such as silicon, thus outperforming the silicon devices in speed and heating control.Lius team and another independent group from the Massachusetts Institute of Technology brought "the practical use of cubic boron arsenide one step closer," according to the editors.Pan and Lius results were published in the journal Science in December and July, respectively.

Study finds genetic solution to pre-harvest sprouting in rice, wheat

A new Chinese scientific study has identified a combination of two crop genes that are in charge of controlling seed dormancy and could be used to reduce the costly phenomenon of pre-harvest sprouting (PHS) in crops such as rice and wheat.arvesting rice in Jiangning District, Nanjing City, east Chinas Jiangsu Province, November 26, 2022. (Photo: CFP)Seed dormancy is an important survival tool for plants, allowing them to survive in negative weather conditions. However, excessive dormancy may shorten cultivation time, so many farmers like to plant low-dormancy species of rice and wheat to get a high rate of seed emergence after sowing.This practice can lead to PHS, a worldwide production problem in which grains germinate on the mother plant before harvest time and often during wet weather, severely reducing grain yield and quality.Researchers from the Institute of Genetics and Developmental Biology (IGDB) under the Chinese Academy of Sciences have identified two genes, namely SD6 and ICE2, which act in combination to control seed dormancy and have great potential for reducing PHS in rice and wheat.They found that SD6 and its interaction partner ICE2 can antagonistically control rice seed dormancy by regulating plant hormones. Specifically, SD6 can promote the expression of the catabolic hormones and inhibit the expression of the anabolic hormones, while ICE2 acts in the opposite manner.In the study, when seeds were at room temperature, SD6 was up-regulated to trigger seed germination. However, at low temperatures, SD6 was down-regulated, but ICE2 was up-regulated to keep the seed dormant.The researchers edited SD6 in three rice species and found that editing the gene could be a rapid and useful strategy for improving PHS tolerance in rice. They then edited the genes in a wheat variety, showing that this provided a similar resistance to PHS.The study results were published in the journal Nature Genetics on Monday.Lead researcher Chu Chengcai said the findings wer...

Boeing's last 747 to roll out of Washington state factory

A Boeing 747-8, Boeings passenger plane, takes its first flight at Paine Field in Everett, Washington, the United States, March 20, 2011. (Photo: AP)After more than half a century, Boeing is set to roll its last 747 out of a Washington state factory on Tuesday.The jumbo jet – which has taken on numerous roles as a cargo plane, a commercial aircraft capable of carrying nearly 500 passengers and as the Air Force One presidential aircraft – debuted in 1969. It was the largest commercial aircraft in the world and the first with two aisles, and it still towers over most other planes.The 747s design included a second deck extending from the cockpit back over the first third of the plane, giving it a distinctive hump that made the plane instantly recognizable and inspired a nickname, the Whale. More elegantly, the 747 became known as the Queen of the Skies.It took more than 50,000 Boeing employees less than 16 months to churn out the first 747. The company has completed 1,573 more since then.But over the past 15 years or so, Boeing and its European rival Airbus released new wide-body planes with two engines instead of the 747s four. They were more fuel-efficient and profitable.Delta was the last U.S. airline to use the 747 for passenger flights, which ended in 2017, although some other international carriers continue to fly it, including the German airline Lufthansa.The final customer is the cargo carrier Atlas Air, which ordered four 747-8 freighters earlier this year. The last was scheduled to roll out of Boeings massive factory in Everett, Washington, on Tuesday night.Boeings roots are in the Seattle area, and it has assembly plants in Washington state and South Carolina. The company announced in May that it would move its headquarters from Chicago to Arlington, Virginia.The move to the Washington, D.C., area puts its executives closer to key federal government officials and the Federal Aviation Administration (FAA), which certifies Boeing passe...

How little-known technologies helped Shenzhou-14 crew return to Earth

China innovated an array of technologies to make sure the Shenzhou-14 crewed spaceship returned safely to Earth on Monday.The bottom of the Shenzhou-14 spaceship is seen in the picture after it landed in north Chinas Inner Mongolia Autonomous Region, December 4, 2022. (Photo: CFP)Different from the previous mission, the reentry of the Shenzhou-14 spaceship was scheduled at night, which meant low temperatures and low visibility.Thermal control systemThe temperatures can be tricky.From the moment the spaceship separated from the space station on the way home, it has to activate its own thermal control system to keep the temperature between 17 and 25 degrees Celsius, an ideal condition for the taikonauts.The spaceships thermal coatings and the insulation do not require powered equipment. It is also equipped with radiators and heaters generating power to keep the inside of the spaceship warm."If the reentry capsule landed in a dessert with a temperature of under minus 25 degree Celsius," said Peng Huakang, technical supervisor of the recovery team at the 5th Academy of Aerospace Science and Technology Group, "The temperature inside can be maintained at 15 degree Celsius for over an hour, with the hatch closed and ventilator shut."When the spaceship reenters Earth atmosphere, the friction can cause temperatures of over 1,000 degree Celsius, so the ship has a heat shield installed on its bottom to resist the high temperature.High efficient communicationThe ground teams including control center in Beijing, landing site and rescue teams use the BeiDou Navigation Satellite System to communicate with each other in real time to increase the efficiency of locating the reentry capsule.The rescue helicopters also have a smart system installed to help predict the path of the reentry capsule during landing.The parachutes of the Shenzhou-14 spaceship unfold before it lands safely in north Chinas Inner Mongolia Autonomous Region, December 4, 20...

As Musk is learning, content moderation is a messy job

A Twitter logo hangs outside the companys San Francisco offices on Nov. 1, 2022. (Photo: AP)Now that he’s back on Twitter, neo-Nazi Andrew Anglin wants somebody to explain the rules.Anglin, the founder of an infamous neo-Nazi website, was reinstated Thursday, one of many previously banned users to benefit from an amnesty granted by Twitters new owner Elon Musk. The next day, Musk banished Ye, the rapper formerly known as Kanye West, after he posted a swastika with a Star of David in it.“Thats cool," Anglin tweeted Friday. “I mean, whatever the rules are, people will follow them. We just need to know what the rules are.”Ask Musk. Since the world’s richest man paid $44 billion for Twitter, the platform has struggled to define its rules for misinformation and hate speech, issued conflicting and contradictory announcements, and failed to full address what researchers say is a troubling rise in hate speech.As the “ chief twit ” may be learning, running a global platform with nearly 240 million active daily users requires more than good algorithms and often demands imperfect solutions to messy situations — tough choices that must ultimately be made by a human and are sure to displease someone.A self-described free speech absolutist, Musk has said he wants to make Twitter a global digital town square. But he also said he wouldnt make major decisions about content or about restoring banned accounts before setting up a “ content moderation council ” with diverse viewpoints.He soon changed his mind after polling users on Twitter, and offered reinstatement to a long list of formerly banned users including ex-President Donald Trump, Ye, the satire site The Babylon Bee, the comedian Kathy Griffin and Anglin, the neo-Nazi.And while Musks own tweets suggested he would allow all legal content on the platform, Yes banishment shows thats not entirely the case. The swastika image posted by the rapper falls in the “lawful but awful” category that...

US police rarely deploy deadly robots to confront suspects

A police officer uses a robot to investigate a bomb threat in San Francisco, on July 25, 2008. (Photo: AP)The unabashedly liberal city of San Francisco became the unlikely proponent of weaponized police robots last week after supervisors approved limited use of the remote-controlled devices, addressing head-on an evolving technology that has become more widely available even if it is rarely deployed to confront suspects.The San Francisco Board of Supervisors voted 8-3 on Tuesday to permit police to use robots armed with explosives in extreme situations where lives are at stake and no other alternative is available. The authorization comes as police departments across the U.S. face increasing scrutiny for the use of militarized equipment and force amid a years-long reckoning on criminal justice.The vote was prompted by a new California law requiring police to inventory military-grade equipment such as flashbang grenades, assault rifles and armored vehicles, and seek approval from the public for their use.So far, police in just two California cities — San Francisco and Oakland — have publicly discussed the use of robots as part of that process. Around the country, police have used robots over the past decade to communicate with barricaded suspects, enter potentially dangerous spaces and, in rare cases, for deadly force.Dallas police became the first to kill a suspect with a robot in 2016, when they used one to detonate explosives during a standoff with a sniper who had killed five police officers and injured nine others.The recent San Francisco vote, has renewed a fierce debate sparked years ago over the ethics of using robots to kill a suspect and the doors such policies might open. Largely, experts say, the use of such robots remains rare even as the technology advances.Michael White, a professor in the School of Criminology and Criminal Justice at Arizona State University, said even if robotics companies present deadlier options at tradeshows, it doesnt mean p...
