Although space travel exposes astronauts to forms of radiation that are uncommon on Earth, and that are linked to cancers and heart problems, a U.S. study suggests this doesn’t significantly shorten their lives.
Researchers compared nearly 60 years of data on U.S. male astronauts and a group of men who are similarly extra-fit, affluent and receive elite health care: pro athletes. They found that neither group has higher rates than the other of death overall or of early deaths. Both groups do tend to outlast the rest of us, however.
Astronauts are generally well-educated, more affluent and more physically fit than the typical American, and some previous research has linked this career to a lower risk of premature death, the study team notes in Occupational & Environmental Medicine.
But much of the previous research on mortality rates in astronauts hasn’t accounted for the mental and physical demands of this career, or the so-called “healthy worker effect” that leads people with employment of any kind to typically have fewer medical issues than individuals who are unable to work, said study co-author Robert Reynolds of Mortality Research & Consulting Inc. in City of Industry, Calif.
Comparable group needed
“The challenge has always been to understand if astronauts are as healthy as they would be had they been otherwise comparably employed but had never gone to space at all,” Reynolds said by email. “To do this, we needed to find a group that is comparable on several important factors, but has never been to space.”
The researchers compared mortality rates for male U.S. astronauts to those of professional athletes from Major League Baseball and the National Basketball Association between 1960 and mid-2018.
Both athletes and astronauts had a lower risk of premature death than the general population, the study found. And there was no meaningful mortality difference between NBA and MLB players.
Astronauts were more likely to die of accidents and other external causes, and less likely to die from heart disease and all other natural causes, the study also found.
“We cannot be sure from the data we have, but we speculate that cardiovascular fitness in particular is the most important factor in astronaut longevity,” Reynolds said.
The results suggest that radiation exposure in space might not lead to a premature death for astronauts due to heart problems or certain cancers, the study authors conclude. In fact, astronauts had a lower rate of death from heart disease than the NBA and MLB players, and had cancer mortality similar to the athletes’ rates.
The study wasn’t designed to prove whether or how space travel may directly impact human health. It also didn’t examine mortality among female astronauts or athletes.
Lower radiation exposure
Radiation exposure may also have been much lower during early missions to the moon and not reflect what would happen with the current generation of astronauts, said Francis Cucinotta, a researcher at the University of Nevada-Las Vegas, who wasn’t involved in the study.
“The missions in the past were low dose, while in the future the dose would be 50 to 100 times higher for a Mars mission,” Cucinotta said by email.
Astronauts have typically never smoked, leading to a lower risk of heart disease than the general population, Cucinotta added.
Diet and exercise also set astronauts and professional athletes apart from the rest of the population, said Michael Delp, a researcher at Florida State University in Tallahassee who wasn’t involved in the study.
“When physical fitness is a requisite part of a job, such as with astronauts and professional athletes, this is a major determinant of the healthy worker effect,” Delp said by email.
Even for the rest of us, “remaining or becoming physically active and maintaining a well-balanced diet greatly improves overall health and well-being, and can enhance successful aging,” Delp said. (VOA)
Ride-hailing major Uber has introduced a new in-app safety feature that will allow drivers as well as riders to record audio during trips.
Initially, the firm announced a feature called Audio Recording in Latin America as a way to make people using Uber there feel more safe. The feature is now available in more than a dozen countries throughout Latin America, including Brazil and Mexico.
"To help protect privacy, the audio file is encrypted and stored on the rider and driver's devices and by default no one can listen to the audio, including Uber. If either user submits a safety report to Uber, they can attach the audio file to their report," the company said in a statement.

Once riders and drivers enable this feature, they can choose to record audio by tapping the shield icon on the map screen and selecting "Record Audio".
Riders and drivers can choose to record individual trips, and drivers will also have the option to leave the feature on while they are online.
Throughout Latin America this feature has been a popular way to promote safe, comfortable interactions while on a trip. For instance, nearly 70 per cent of riders and drivers surveyed in Rio de Janeiro told the brand this feature helped them feel safer when using Uber.
In addition, the company has expanded the capabilities of our RideCheck technology to detect when a trip takes an unexpected route or when a trip ends unexpectedly before the rider's final destination.
Uber first introduced RideCheck in 2019, using GPS data and sensors in the driver's smartphone to detect possible crashes or an unusually long stop during a trip.

Based on feedback from drivers, the firm will soon launch a new proactive, audio seat belt alert that reminds riders to buckle up at the start of a trip.
The audio alert will come from the driver's phone and will be accompanied by a push notification to the rider's phone reminding them to buckle up.
"We believe this new feature, which will be available nationally early next year, will increase seat belt use and help drivers ensure a safe environment while on a trip," the company noted.

Special Powers For The Armed Forces Act Of 1958 is an act to allow personnel of the armed forces in the states of *[Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura] to be granted certain special powers in troubled regions.
In protest, Nagaland has decided to put the Hornbill Festival on hold. Furthermore, the SIT investigating the event has been given a month to finish its inquiry.
The Nagaland administration has decided to petition the Home Ministry to abolish the Armed Forces (Special Powers) Act in the wake of the killing of 14 people by security forces (AFSPA). On Tuesday, the decision was made during a cabinet meeting presided by Chief Minister Neiphiu Rio.

The Special Inquiry Team (SIT) that has been formed to investigate the event, would conclude its investigation within a month, according to the meeting. In response to the innocent fatalities, the government has decided to cancel the current Hornbill Festival. The venue's stalls will stay open, and the tourist bureau will stage a brief closing ceremony.
The 10-day Hornbill Festival, the state's major tourist event, was set to culminate on December 10 at Naga Heritage Village in Kisama, near the state capital. The day's event at the location had been cancelled by the state authorities on Monday.
Following the deaths in Mon district, several tribes from eastern Nagaland and other areas of the state halted all activity at their respective Morungs.
Security forces were in the middle of an ambush when the vehicle approached the location and tried to flee when signaled to stop by the forces. It being suspected of carrying insurgents, the security forces opened fire. Later on it came into light it was a case of mistaken identity and they were civilians who worked as coal mine workers and were coming home in a car. Out of the eight individuals in the vehicle, six died instantly. This sparked additional violence in the region, which resulted in the deaths of eight more individuals (seven on Saturday and one on Sunday) and one security personnel.
Union Home Minister Amit Shah expressed remorse to Parliament on Monday, saying that on December 4 evening, "a squad of 21 para-commandos of the Indian Army planned an ambush" for terrorists in Mon area, but that it "turned out to be a case of mistaken identification." "The Government of India offers its profound condolences to the families of those who have lost their lives," he continued.
The officer in-charge of the Tizit police station in Mon district filed a suo-motu FIR on Sunday alleging that the security forces' "intention" was "to murder and hurt people."
On December 4, the coal mine laborers who were from Oting village had been returning home from Tiru in a Bolero when, "on reaching Longkhao, between Upper Tiru and Oting villages, security forces blankly open fired at the vehicle without any provocation, resulting in the death of many Oting villagers and seriously injuring many others," according to a FIR filed by Ubi Posehu Kezo, the officer in charge of the Tizit police station.
According to the FIR, there was no police guide present at the time of the event, and security personnel did not "submit a demand to the police station to supply police guide for their operation." As a result, it is clear that the security forces' goal is to kill and hurt people."

The Army has expressed great remorse for the occurrence and has convened a Court of Inquiry into it. "The reason for the tragic loss of lives is being probed at the highest level by a Court of Inquiry, and necessary action will be taken in accordance with the law," it stated.
Rio had joined a rising chorus of demands for the repeal of AFSPA, which provides security personnel exceptional powers in "disturbed regions," when attending the funeral of the 14 people in Mon town on Monday.
Meanwhile, the Konyak Union (KU), Nagaland's main tribal organisation, declared a day-long bandh in the Mon district on Tuesday to condemn the deaths, and a seven-day mourning period began the next day.
The KU has advised security troops to refrain from patrolling the Konyak region during the seven-day mourning period, warning that if they do not, they would be held accountable for "any unpleasant occurrence that may occur."
In a letter sent on Monday, the union asked President Ramnath Kovind to form a Special Investigation Team (SIT) "also comprising two members of the Eastern Nagaland People's Organisation (ENPO) in it" to identify the Army personnel involved in the incident and make public the actions taken against them within 30 days.
It asked that the 27 Assam Rifles leave Mon immediately for failing to safeguard residents, as well as the removal of the Armed Forces (Special Powers) Act from the whole Northeast.
"On Tuesday, we declared a day-long bandh in Mon district. It is proceeding in a calm manner. We've also declared a seven-day mourning period beginning on Wednesday," Howing Konyak, head of the Konyak Union, told PTI.

Samsung Electronics on Tuesday replaced all three CEOs in a surprise move that, the company said, was intended to enhance competitiveness and promote future growth.
Han Jong-hee was promoted to vice chairman and CEO and will be in charge of the newly created SET division, which merged the consumer electronics and IT and mobile communications divisions, previously led by Kim Hyun-suk and Koh Dong-jin, respectively.

An expert in TV research and development, Han played a key role in bringing the company's TV business to the top position. Samsung said he is expected to "strengthen the synergies among the different businesses in the SET division and help drive new businesses and technologies." The device solutions (DS) division will be led by Kyung Kye-hyun, who has been Samsung Electro-Mechanics CEO.
Kyung is a semiconductor design expert, having previously led the company's flash product and technology team. Samsung said he is expected to "help maintain the company's semiconductor leadership and lead innovation in the components business."

Kim Ki-nam, vice chairman and head of the DS division, was named chairman of Samsung Advanced Institute of Technology, reports Yonhap news agency.
The tech giant said in a statement the new appointments were made "for the next phase of the company's future growth and to strengthen its business competitiveness."
The reshuffle came as a surprise as it had been widely expected that the tech giant would keep its current division heads to ensure a stable management environment amid fierce global competition and potential risks associated with the ongoing trial of Samsung Electronics Vice Chairman Lee Jae-yong over his role in controversial merger and accounting fraud allegations.

The three CEOs had been considered successful in leading the company to post stellar performances since 2018 and were endorsed to keep their posts during the annual shareholders meeting in Suwon, south of Seoul, in March.
But Lee, the de facto leader of the country's biggest conglomerate, Samsung Group, has hinted at making a sizable change to the company to "create a better Samsung." He also warned of the "harsh reality of the market" amid the global supply crunch and chip shortages.
The management reshuffle came a week after the company overhauled its position system and abolished the seniority-based top-down approach to nurture young talent and create a more flexible corporate culture. It scrapped mandatory years of working at certain positions, a precondition for possible promotion, and incorporated ranks to make the company structure more simplified and nimble.
Lee did not get promoted to chairman of Samsung Electronics -- the crown jewel of Samsung Group. He assumed the vice chairman position in December 2012. The chairman position has been left vacant since his father, Lee Kun-hee, died in October last year. (IANS/SP)
