The surprising results of a decade-long investigation by Alessandro Vezzosi and Agnese Sabato provide a strong basis for advancing a project researching the DNA of Renaissance master Leonardo da Vinci.
Their extensive study, published by the journal 'Human Evolution, documents with new certainty the continuous male line, from father to son, of the Da Vinci family (later Vinci), from progenitor Michele (born 1331) to grandson Leonardo (sixth generation, born 1452) through to today -- 21 generations in all, including five family branches -- and identifies 14 living descendants.
The work fills the gaps and corrects the errors in the previous genealogical research into Leonardo's family while offering discoveries and family tree updates.
This text deepens and enormously expands the discovery announced in Vinci, Italy, in 2016 by the same Vezzosi and Sabato of numerous living but indirect descendants, including only two males in a direct line, up to the 19th generation, from a single branch of the Vinci family.
It also provides for the first time the documentary data and information sources over seven centuries to the present day registry office, with work on additional family branches ongoing.
Leonardo himself had at least 22 half-brothers but no children; a new unpublished document shows that "Paolo di Leonardo da Vinci da Firenze" was a case of homonymy. The five family branches are traced from Leonardo's father, ser Piero (fifth generation), and half-brother Domenico (sixth).
Since the 15th generation, data have been collected on over 225 individuals. The study, with the collaboration of the living descendants, contributes to the work of the Leonardo Da Vinci Heritage Association.
This extraordinary, authoritative 690-year genealogical investigation is fundamental to affiliated scientific work Vezzosi and Sabato have underway with the international Leonardo da Vinci DNA project, supported by The Richard Lounsbery Foundation.
The project involves the J. Craig Venter Institute of La Jolla, California, and several other high-profile universities and research centres, including the Department of Biology of the University of Florence, directed by David Caramelli.
The Y chromosome, passed on to the male descendants, is known to remain almost unchanged through 25 generations. Comparing the Y chromosome of today's male relatives to that of their ancestors in ancient and modern burial sites would both verify the uninterrupted family line and certify Leonardo's own Y chromosome marker.

Questions potentially probed once Leonardo's DNA is confirmed include reasons behind his genius, information on his parents' geographical origins, his physical prowess, premature ageing, left-handedness, diet, health and any hereditary diseases, and his extraordinary vision, synaesthesia and other sensory perceptions.
Comparison of biological data could also potentially help verify the authenticity of artwork and materials handled by Leonardo, thereby pioneering links between biology and art with broad implications for the world's art market in terms of artistic attribution and materials. (IANS/AD)
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)
