Twitter made it easier to see quote tweets on iOS on May 12th, and that new functionality is now available on Twitter for Android and for the web, the company announced today.
If you tap or click on the “Retweets” word on a tweet, you’ll be taken to a new page that lets you look at one of two columns: a column showing retweets with comments and a column showing all retweets without comments.
The new feature the latest of many that Twitter has rolled out recently to make it easier to follow and track conversations on the platform. One that I’m a particular fan of is the new interface for threaded conversations, which is available to some iOS and web users. And just yesterday, Twitter began testing a way to let users limit replies to tweets, which could help prevent abuse and harassment on the platform but does have some thorny implications for politicians’ tweets and the spreading of misleading or fake information.

Scientists have tested 14 different types of face-covering and found that one of them actually increases the risk of coronavirus infection.
Researchers at Duke University in North Carolina tested coverings ranging from the kind worn by healthcare professionals to neck fleeces and knitted masks.
The study's authors compared the dispersal of droplets from a participant's breath while they were wearing one of the coverings to the results of a control trial where their mouth was fully exposed.
The least effective face-covering in the study was a neck fleece which was found to actually increase the risk of infection by having a "droplet transmission fraction" of 110%.
Duke University researcher Martin Fischer, who put the test together, told CNN: "We were extremely surprised to find that the number of particles measured with the fleece actually exceeded the number of particles measured without wearing any mask.
"We want to emphasise that we really encourage people to wear masks, but we want them to wear masks that actually work."
A bandana was the second worst-performing face-covering but it did not increase the risk of infection, while a knitted covering was third worst.

Facebook’s VR research division is presenting prototype VR optics smaller than any we’ve seen yet for the annual SIGGRAPH computer graphics conference.
The ideas behind the “holographic near-eye display” could one day enable VR headsets with sunglasses form factor- but for now this is solely research with limitations.
Facebook Reality Labs’ new approach is a thin film where focusing is done by holographic optics instead of by the bulk of the lens. ‘Hologram’ in this context just means a physical “recording” of how light interacts with an object- in this case a lens rather than a scene.
Facebook claims the research may be able “to deliver a field of view comparable to today’s VR headsets using only a thin film for a thickness of less than 9 mm.” The total weight of the display module is claimed as just 18 grams. However, this does not include the actual laser source, and nor do any of the images Facebook provided. “For our green-only sunglasses-like prototype, we measured an overall maximum field of view of approximately 92◦ ×69◦,” according to the research paper.
By using polarization-based optical folding, these ultra-lightweight lenses can be placed directly in front of the display source.

Washington: The global economy, which has plunged into a severe contraction, will shrink by 5.2 per cent this year due to the massive shock of the coronavirus pandemic and the shutdown measures to contain it, the World Bank said on Monday.
The COVID-19 recession is the first since 1870 to be triggered solely by a pandemic, World Bank President David Malpass said in his foreword to the latest edition of the Global Economic Prospect report released on Monday.
The World Bank report said that the global economy has experienced 14 global recessions since 1870: in 1876, 1885, 1893, 1908, 1914, 1917-21, 1930-32, 1938, 1945-46, 1975, 1982, 1991, 2009 and 2020.
Current forecasts suggest that in 2020, the highest share of economies will experience contractions in annual per capita GDP since 1870, it said.
The share of economies in recession will be more than 90 per cent, even higher than the proportion of about 85 per cent of countries in recession at the height of the Great Depression of 1930-32, it added.

Let's take a first look at some of the new features coming to Android 11. We're running the public beta on a Pixel 4 and looking at Android's new bubble messages, changes to notifications, a built-in screen recorder (yay!) and some more flexible media controls.

Earth has proven unique in its ability to host life in the universe so far, leading us to question if we're truly alone.
Maybe we're not.
Scientists have calculated that there could be a minimum of 36 active, communicating intelligent civilizations in our Milky Way galaxy, according to a new study. However, due to time and distance, we may never actually know if they exist or ever existed.
The study published Monday in The Astrophysical Journal.
Previous calculations along these lines have been based on the Drake equation, which was written by astronomer and astrophysicist Frank Drake in 1961.
"Drake developed an equation which in principle can be used to calculate how many Communicating Extra-Terrestrial Intelligent (CETI) civilizations there may be in the Galaxy," the authors wrote in their study. "However, many of its terms are unknowable and other methods must be used to calculate the likely number of communicating civilizations."
So scientists at the University of Nottingham developed their own approach.
"The key difference between our calculation and previous ones based on the Drake equation is that we make very simple assumptions about how life developed," said study coauthor Christopher Conselice, a professor of astrophysics at the University of Nottingham, in an email to CNN.
"One of them is that life forms in a scientific way — that is if the right conditions are met then life will form. This avoids impossible to answer questions such as 'what fraction of planets in a habitable zone of a star will form life?' and 'what fraction of life will evolve into intelligent life?' as these are not answerable until we actually detect life, which we have not yet done."
They developed what they call the Astrobiological Copernican Principle to establish weak and strong limits on life in the galaxy. These equations include the history of star formation in our galaxy and the ages of stars, the metal content of the stars and the likelihood of stars hosting Earth-like planets in their habitable zones where life could form.
The habitable zone is the right distance from a star, not too hot or too cold, where liquid water and life as we know it may be possible on the surface of a planet.
Despite offering the best cameras you can find on a smartphone, Google's Pixel lineup hasn't been able to break the stranglehold Apple and Samsung enjoy on the smartphone market. But a Google survey hints that the phone maker may be looking to compete on price with this year's Google Pixel 5 release.
As spotted by Android Authority, a Reddit user posted a screenshot of a phone price survey Google's apparently been circulating around. If the survey's legitimate — and it does seem like the sort of thing a company to gauge expectations and interest in upcoming releases — then the Pixel 5 might be one of the lowest-priced flagships around this fall.

The survey mentions two Pixel releases — one that's labeled as a "Google Pixel Phone" with a plastic body and 3.5mm headphone jack. That phone is listed at $349, while a second model described as a "Premium Google Pixel Phone" with "best in class camera, wireless charging and water resistance" would cost $699.
