Researchers map America’s changing racial diversity

New York, April 22: Researchers in the US have created a digital map to track the changing racial diversity of every neighbourhood in the country.

The map shows which neighbourhoods have become less homogenous over the last two decades and which have not.

Tomasz Stepinski from University of Cincinnati applied NASA mapmaking techniques to 20 years of data collected by the US Census Bureau to build one of the most detailed racial-diversity maps ever created.

The zoomable map, a paper about which was published in the journal PLOS One, shows at a glance how the racial composition of neighbourhoods changed between 1990 and 2010.

“People don’t realise that the United States is a diverse country but at the same time is still very segregated,” Stepinski, who created the map in collaboration with his postdoctoral researcher Anna Dmowska, said.

The researchers think that the map will have broad appeal to journalists, policymakers and researchers.

“The maps can tell us much more about racial composition and can be used by everyone,” Dmowska, who now works at the Institute of Geoecology and Geoinformation of Adam Mickiewicz University in Poland, said.

“They don’t require expert knowledge to understand the results, so I think maps can be used by a broader community,” Dmowska said.

Updating the maps in future census years will be relatively simple, she said.

“Our grids are ready to use for multiyear comparison,” Dmowska added.

The maps allow users to create their own smaller study area and then glean data from it.

In some cities, they tell the story of recent immigration in America. For example, the maps demonstrate the influx of Asian immigrants in San Francisco over the last 20 years.

Many of these newcomers are Southeast Asians who were drawn to the area by the Silicon Valley boom, Stepinski said.

And in Cincinnati, too, the census maps track the changing racial composition of the city.

Neighbourhoods that were predominantly White or Black in 1990 are far more diverse now.

But they also show the way that racial segregation has defined some cities.

For example, in the Detroit neighbourhoods popularised by the movie “8 Mile,” the map from 1990 clearly shows the segregation of Black and White communities on either side of 8 Mile Road.

New Delhi, July 12 : Google recently announced that Assistant would be able to make video and audio calls with WhatsApp.

This means that one can easily access WhatsApp and some of its options by triggering the Google Assistant from the home screen on your smartphone.

The voice calls commenced by Assistant were earlier used to place a network call for the user. While video calls could be set up via Hangouts or Duo only.

If you have set up the Google Assistant app on your Android device, you may directly invoke it by saying OK Google or Hey Google.

One may also wake up the assistant app using the dedicated key, if available or by long-pressing the Home button on your device.

When Google Assistant is open, use one of the two commands, “Make a WhatsApp call to [contact-name]” or “Call [contact-name] on WhatsApp and for video call just say “Make a WhatsApp video call to [contact-name]”.

To make things faster, one should add a nickname to the most frequently called contacts.

Bill Gates warns ‘deadlier pandemic’ if vaccine goes to ‘highest bidders’

There are at least 21 vaccines currently under key trials, according to the World Health Organisation (WHO).

San Francisco, July 12 : Microsoft founder Bill Gates has warned about a deadlier pandemic if successful drugs or a COVID-19 vaccine, when developed, go first to the highest bidders and not reach the common people who need it the most.

Addressing a remote COVID-19 conference hosted by the International AIDS Society on Saturday, Gates said democratizing the vaccine must be the goal, reports CNBC.

“If we just let drugs and vaccines go to the highest bidder, instead of to the people and the places where they are most needed, we”ll have a longer, more unjust deadlier pandemic,” he said.

“We need leaders to make these hard decisions about distributing based on equity, not just on market-driven factors,” Gates added.

There are at least 21 vaccines currently under key trials, according to the World Health Organisation (WHO).

The fear is that once the vaccine is developed, the rich and the powerful people would grab it first.

However, despite encouraging preliminary data coming from some research labs, a Covid-19 vaccine is nowhere near while new corona cases are mounting in several countries including in India.

No vaccines have yet started their large and critical Phase-III trials in the US.

WHO Chief Scientist Soumya Swaminathan has said that AstraZeneca”s coronavirus vaccine candidate is currently the most advanced vaccine in terms of development.

AstraZeneca”s Covid-19 vaccine candidate, developed by researchers from the Oxford University, will likely provide protection against the disease for one year, the British drug maker”s CEO told Belgian radio station Bel RTL recently.

The vaccine developed at the Oxford Jenner Institute is currently on trial in the UK, where over 4,000 participants have enrolled and additional enrollment of 10,000 participants is planned for the clinical trial. The ChAdOx1 nCoV-19 vaccine has been licenced to AstraZeneca.

“Global cooperation, a resolve to invent the tools and get them out where they”re needed most is critical,” said Gates at the virtual event.

Gates in May said the vaccine development may take at least nine months to two years.

“Most of the drug candidates right now are nowhere near that powerful. They could save a lot of lives, but they aren”t enough to get us back to normal,” the Microsoft co-founder wrote in his GatesNotes blog.

In the absence of an “almost perfect drug to treat COVID-19”, it becomes imperative that every person on the planet gets vaccinated against coronavirus.

“Realistically, if we”re going to return to normal, we need to develop a safe, effective vaccine. We need to make billions of doses, we need to get them out to every part of the world, and we need all of this to happen as quickly as possible,” he said.

Google to boost fake news, illegal content monitoring on YouTube

In a blog post, Pichai said that since January, Google has blocked hundreds of thousands of ads attempting to capitalize on the coronavirus pandemic.

Seoul, July 12 : Google’s video-sharing platform YouTube will cooperate with South Korea to closely monitor and prevent the spread of fake news and illegal content.

Google’s Senior Vice President Neal Mohan made the comments during a videoconference with Han Sang-hyuk, chairman of the Korea Communications Commission (KCC).

The remarks came after Han requested such cooperation, considering fake news surrounding Covid-19 and a recent high-profile digital sexual abuse case in South Korea, in which such illegal materials were distributed across social media platforms.

The regulator has kept a close watch over the tech giant this year.

Last month, Google voluntarily corrected subscription practices on its YouTube Premium service in the country, after the KCC found they were unfair for users.

The regulator also imposed a fine of $720,000 on Google for violating local telecom laws, as it did not properly notify users of YouTube Premium’s charged service.

In March this year, Alphabet and Google CEO Sundar Pichai said the company has taken down thousands of videos on YouTube related to dangerous or misleading coronavirus information using its Artificial Intelligence (AI)-based technology.

In a blog post, Pichai said that since January, Google has blocked hundreds of thousands of ads attempting to capitalize on the coronavirus pandemic.
