Scientists from the University of Texas at Austin have finally solved the mystery of a massive fossil that has been sitting unlabeled and unidentified at a Chilean museum for almost a decade. The relic, which resembles a deflated football, is the largest-known soft-shelled egg from a marine reptile that inhabited Earth over 66 million years ago — about the time of the mass animal extinction event. Measuring more than 11 by 7 inches it is also the second-largest egg belonging to any known animal, behind only the now-extinct elephant bird....

To the novice baker, the classic teardrop-shaped baking chip, created by Nestle in 1941, may appear like the perfect mechanism to introduce specks of chocolate to cookies and other treats. However, experts assert that the chip's dense bottom, which blocks the oven heat to retain some shape, prevents the consumer from fully experiencing the luxurious feel and taste of the melted chocolate. Now, Tesla engineer Remy Labesque has rectified the decades-old design flaw with a stylish, pyramid-shaped version that purportedly melts in your mouth, instead of sticking to the teeth like traditional chocolate chips....

North America's relatively calm summer weather ended last week when a powerful derecho swept across the Midwest — from South Dakota to Ohio — on August 10, 2020, and a rare firenado struck Northern California on August 15, 2020. If you are like most people, you have probably never heard of either of the rare natural phenomena. Here is a brief explanation of the incredible extreme weather events....

While astronomers have discovered evidence of thousands of exoplanets, obtaining direct images of the distant worlds has always been a challenge. That's because the planets tend to huddle close to the star they orbit and often get concealed by their star's dazzling light. Of the handful of images captured, most are of a single planet orbiting a Sun-like star. The only two multi-planet systems photographed feature brown dwarfs, or "failed stars," which are radically different in nature from the Sun. Now, an international team of scientists may have finally captured a young, Sun-like star with two giant Jupiter and Saturn-like planets in orbit....

On August 11, 2020, presumptive Democratic presidential nominee Joe Biden made history by announcing California Senator Kamala Harris as his running mate for the upcoming election. Harris, who is the daughter of immigrants from Jamaica and India, is the first African American woman on a major party ticket and only the fourth woman in US history to run for vice president. She is also the first person of Asian descent to appear on a presidential ticket....

Over the years, researchers have made numerous attempts to make Harry Potter's invisibility cloak a reality. While each version has been slightly better, none have come close to the one donned by the young wizard. Now, scientists may be able to get some tips from an unlikely source — ultra-black deep-sea fish that have evolved the capability to hide in plain sight to avoid detection....

Summer 2020 has been exciting for stargazers. They have been treated to a once-in-a-lifetime visit from comet NEOWISE and had the rare opportunity to observe five planets and a full moon simultaneously, among other celestial events. Now, to top it all off, come the Perseids — the biggest and most spectacular meteor showers of the year....

SpaceX's first-ever passenger flight to the International Space Station (ISS) ended successfully on August 2, 2020, when Crew Dragon Endeavour splashed into the Gulf of Mexico off the coast of Pensacola, Florida. After a series of safety checks, the recovery teams unlocked the capsule's hatch and quickly whisked the spacecraft's precious cargo — NASA astronauts Bob Behnken and Doug Hurley — to shore. During their total 64 days in space, the astronaut duo completed 1,024 orbits around Earth and traveled 27,147,284 miles....

Male birds typically sing the same tunes as the rest of their species because an unrecognizable song defeats the two primary reasons for their crooning — to establish and defend their territory and to attract mates. While the songs, which are passed down from generation to generation, may vary slightly by region, any new compositions are typically limited to the local environment. However, for reasons unknown to scientists, white-throated sparrows across Canada are abandoning their classic song for a catchy new tune "written" by their peers in British Columbia....
