Given that white was one of the first colors used in art in the 15th century, one would think that there is little room left to improve its "whiteness." It turns out that is far from the case. A team of researchers led by Xiulin Ruan, a professor of mechanical engineering at Indiana's Purdue University, recently revealed an "ultra-white" paint that they believe could even help combat climate change.
Since landing on Mars on February 18, 2021, NASA's Perseverance rover has achieved numerous "firsts," including beaming audio sounds from the Red Planet's surface. It also made history as the first spacecraft to record sounds from another spacecraft — the Ingenuity helicopter — on another planet.
On April 22, 2021, for the second consecutive year, the US House of Representatives voted 216-208 to make Washington, DC, the nation's 51st state. Though the symbolically titled H.R. 51 bill is identical to the one passed on June 26, 2020, the legislation was never put to the vote in the then Republican-controlled Senate. However, this time around, the bill — which has the support of both President Joe Biden and Democratic Majority Leader Charles E. Schumer — will get a hearing in the upper house of Congress.
Every April 22, over a billion people around the world celebrate Earth Day by participating in neighborhood clean-up activities and environmental teach-ins. The planet's largest civic event began in 1970 when twenty million Americans poured out onto the streets to urge lawmakers to take action to protect the environment before it was too late. Now boasting over 50,000 partners in 195 countries, the Earth Day Network (EDN) has led to the establishment of numerous environmental policies, including the Clean Air Act, the Clean Water Act, and the Endangered Species Act.
Fifteen US states, including New York, Illinois, Georgia, Virginia, Maryland, New Jersey, as well as Washington D.C., will soon be buzzing with billions, and perhaps even trillions, of cicadas. The noisy, red-eyed members of Brood X, which have been hibernating underground for the past 17 years, will emerge unannounced as soon as the conditions are right: the soil is 64 degrees, and on a night that's humid enough but free of wind and rain.
For the more than a billion Muslims worldwide, there is nothing more sacred than the month of Ramadan, or Ramazan. It was during this ninth month of the Islamic lunar calendar that Jibril (the Archangel Gabriel in the Judeo-Christian faith) revealed the first verses of the Quran — Islam's holy text — to the prophet Muhammad. The auspicious month's start, based on the appearance of the super-slim young crescent Moon, is determined by moon-sighting committees in various Muslim countries, most notably in Saudi Arabia. This year, Ramadan will begin on Monday, April 12th, or Tuesday, April 13th.
When Christie's set out to auction its first-ever digital-only artwork — "Everydays: The First 5000 Days"— on March 1, 2021, they had fully expected it to fetch more than the minimum bid of $100. However, the 255-year-old British auction house had never in its wildest dreams envisioned that the unique masterpiece, minted by Mike Winkelmann, aka Beeple, would fetch a record $60.25 million ($69.3 million with fees).
Easter, which will be observed on April 4, 2021, is the oldest and most important Christian festival. Many adults commemorate the holiday, which celebrates the resurrection of Jesus Christ on the third day after his Crucifixion, with prayers and fasting for 40 days before the event. For children in the US, Easter is largely about fun activities like seeking out candy-filled eggs, meeting the Easter bunny, and participating in spring parades. However, not everyone celebrates this all-important holiday with these traditions.
