Zuckerberg asks Harvard graduates to fight isolationism, nationalism

May 26, 2017

San Francisco, May 26: Facebook Inc. chief executive officer Mark Zuckerberg told Harvard graduates that they need to help others find purpose in a world where machines are taking away some of the steady jobs and communities aren"t as stable, leading to isolation and nationalism instead of people coming together globally to solve problems.

“When our parents graduated, purpose reliably came from your job, your church, your community,” Zuckerberg, 33, said in a commencement speech. “But today, technology and automation are eliminating many jobs. Membership in a lot of communities has been declining. Many people feel disconnected and depressed, and are trying to fill a void in their lives.”

The social network Zuckerberg started in his Harvard dorm room now has 1.94 billion users around the world, large enough for the CEO to feel pressure about its impact on society. Zuckerberg has spent this year travelling around the US to understand what people feel about Facebook and how they form connections with each other, after the country"s presidential election revealed deep divides.

Zuckerberg said that on his tour around the states, he met opioid addicts and others who had fallen on hard times with factory closings, who said they might not have suffered if they had something to do. Stress felt by many American communities will increase as tens of millions of jobs are replaced by automation, such as self-driving cars and trucks, Zuckerberg said. Without a sense of purpose, people will turn towards isolationism, nationalism and authoritarianism, instead of openness and global community, he said.

“There"s pressure to turn inwards,” Zuckerberg said. “This is the struggle of our time. This is not a battle of nations, it is a battle of ideas.”

Unless people work together globally, they can"t stop disease pandemics or climate change, he said.

“We have the potential to do so much more together,” Zuckerberg said. He spoke of the achievements of previous generations, such as the moon landing and inventing the polio vaccine. “Now it"s our generation"s turn to do great things. Ideas don"t come out fully formed, they only become clear as you work on them. You just need to get started.”

He suggested stopping climate change by putting people to work manufacturing solar panels, curing disease by getting people to volunteer their health and genome data, and modernizing democracy so people can vote online.

Zuckerberg said that it will cost money to help society, and that people who are rich like him should pay. Zuckerberg, the world"s fifth-richest person, and his wife, Priscilla Chan, have a philanthropic foundation and have pledged to give away virtually all of their considerable wealth in Facebook shares.

He called for affordable childcare and health care that doesn"t just come from an employer, and asked Harvard graduates to volunteer their time, not just their money, to people who don"t have the same opportunity.

The Facebook founder, who dropped out of the university in 2004 to work full-time on the social network, is the youngest person to deliver a commencement speech at Harvard and was given an honorary degree for the effort.

Toronto, May 7: Scientists have uncovered how bats can carry the MERS coronavirus without getting sick, shedding light on what triggers coronaviruses, including the one behind the COVID-19 pandemic, to jump to humans.

According to the study, published in the journal Scientific Reports, coronaviruses like the Middle East respiratory syndrome (MERS) virus, and the COVID19-causing SARS-CoV-2 virus, are thought to have originated in bats.

While these viruses can cause serious, and often fatal disease in people, bats seem unharmed, the researchers, including those from the University of Saskatchewan (USask) in Canada, said.

"The bats don't get rid of the virus and yet don't get sick. We wanted to understand why the MERS virus doesn't shut down the bat immune responses as it does in humans," said USask microbiologist Vikram Misra.

In the study, the scientists demonstrated that cells from an insect-eating brown bat can be persistently infected with MERS coronavirus for months, due to important adaptations from both the bat and the virus working together.

"Instead of killing bat cells as the virus does with human cells, the MERS coronavirus enters a long-term relationship with the host, maintained by the bat's unique 'super' immune system," said Misra, one of the study's co-authors.

"SARS-CoV-2 is thought to operate in the same way," he added.

Stresses on bats, such as wet markets, other diseases, and habitat loss, may have a role in coronavirus spilling over to other species, the study noted.

"When a bat experiences stress to their immune system, it disrupts this immune system-virus balance and allows the virus to multiply," Misra said.

The scientists, involved in the study, had earlier developed a potential treatment for MERS-CoV, and are currently working towards a vaccine against COVID-19.

While camels are the known intermediate hosts of MERS-CoV, they said bats are suspected to be the ancestral host.

There is no vaccine for either SARS-CoV-2 or MERS, the researchers noted.

"We see that the MERS coronavirus can very quickly adapt itself to a particular niche, and although we do not completely understand what is going on, this demonstrates how coronaviruses are able to jump from species to species so effortlessly," said USask scientist Darryl Falzarano, who co-led the study.

According to Misra, coronaviruses rapidly adapt to the species they infect, but little is known on the molecular interactions of these viruses with their natural bat hosts.

An earlier study had shown that bat coronaviruses can persist in their natural bat host for at least four months of hibernation.

When exposed to the MERS virus, the researchers said, bat cells adapt, not by producing inflammation-causing proteins that are hallmarks of getting sick, but instead by maintaining a natural antiviral response.

On the contrary, they said this function shuts down in other species, including humans.

The MERS virus, the researchers said, also adapts to the bat host cells by very rapidly mutating one specific gene.

These adaptations, according to the study, result in the virus remaining long-term in the bat, but being rendered harmless until something like a disease, or other stressors, upsets this balance.

In future experiments, the scientists hope to understand how the bat-borne MERS virus adapts to infection and replication in human cells.

"This information may be critical for predicting the next bat virus that will cause a pandemic," Misra said.

Citing the current dismal aviation scenario, Air India is terminating the services of trainee cabin crew and cabin crew by withdrawing the offer of employment of those who were under training.

As per sources, the new crew and trainee pilots might reduce contracts from five years to one year. Sources said Air India is terminating 1,200 crew and employees who are more than 55-yr-old including 190 trainee pilots.

In a letter reviewed by IANS, Air India has informed an applicant who had been selected as cabin crew in August 2019 subject to successful completion of training.

"On behalf of Air India we would like to thank you for the interest shown by you in joining our organization. However, in view of the current aviation scenario, it would not be possible for Air India to impart any further training to you for engaging your services," the company said.

"In view of the above reasons, which are beyond the control of the company, it has been decided to discontinue your training arrangements and dispense with the offer of engagement with immediate effect. The bank guarantee furnished by you at the time of joining is returned herewith," Air India told the cabin crew.

"Once again on behalf of Air India we thank you for your cooperation and trust that you will appreciate the circumstances under which we are constrained to discontinue the training arrangements," the carrier said.

Google has indexed invite links to private WhatsApp group chats, meaning anyone can join various private chat groups (including several porn-sharing groups) with a simple search.

According to a report in Motherboard, invitations to WhatsApp group chats were being indexed by Google.

The team found private groups using specific Google searches and even joined a group intended for NGOs accredited by the UN and had access to all the participants and their phone numbers.

Journalist Jordan Wildon said on Twitter that he discovered that WhatsApp's "Invite to Group Link" feature lets Google index groups, making them available across the internet since the links are being shared outside of WhatsApp's secure private messaging service.

"Your WhatsApp groups may not be as secure as you think they are," Wildon tweeted on Friday, adding that using particular Google searches, people can discover links to the chats.

According to app reverse-engineer Jane Wong, Google has around 470,000 results for a simple search of "chat.whatsapp.com", part of the URL that makes up invites to WhatsApp groups.

WhatsApp spokesperson Alison Bonny said: "Like all content that is shared in searchable public channels, invite links that are posted publicly on the internet can be found by other WhatsApp users."

"The links that users wish to share privately with people they know and trust should not be posted on a publicly accessible website," Bonny told The Verge.

Danny Sullivan, Google's public search liaison, tweeted: "Search engines like Google & others list pages from the open web. That's what's happening here. It's no different than any case where a site allows URLs to be publicly listed. We do offer tools allowing sites to block content being listed in our results."
