Killer whales, or orcas, are the largest members of the oceanic dolphin family. While the intelligent mammals, which hunt in large pods, are known for their orchestrated attacks on unsuspecting marine animals, they have never posed a threat to humans. However, since late July, the normally social animals have been intentionally attacking sailboats off the coasts of Spain and Portugal. The unusual hostility is puzzling scientists worldwide....

Human hair is about 50 times softer than a razor blade, which is made using heat-hardened stainless steel and often reinforced with diamond-like carbon. Yet, a few wisps of hair are powerful enough to dull a blade's sharpness within a few weeks of use. To understand how this impressive feat occurs, a team of researchers from the Massachusetts Institute of Technology (MIT) decided to take a closer look at what happens when the sharp edge of a blade slices through human hair....

Researchers have long been aware of the presence of rust, or hematite, on Mars caused by the chemical reaction between the iron ore on the planet's surface and water and oxygen from the ancient past. However, they had never expected to find the reddish-brown iron oxide on the Moon, given that our satellite is missing two of the three key components — moisture and oxygen. Now, a new study, based on recent data from India's Chandrayaan-1 Moon-orbiting spacecraft, suggests that the Moon is displaying signs of rust and it may be Earth's fault....

Supreme Court Justice and feminist icon Ruth Bader Ginsburg died at her home in Washington, DC, on September 18, 2020, from complications of metastatic pancreatic cancer. The 87-year-old, who was appointed to the nation's highest court by President Bill Clinton in 1993, was the longest sitting Supreme Court Justice. She was also only the second woman, after Justice Sandra Day O'Connor, to serve in this position....

Most people would shudder at the idea of getting caught up in a 73.5-foot wave. But for Brazilian pro-surfer Maya, it presented the perfect opportunity to break her 2018 world record for the largest wave surfed by a female. The athlete skillfully maneuvered the massive swell earlier this year, at the inaugural World Surf League (WSL) Nazaré Tow Surfing Challenge in Praia do Norte, Portugal. It was the same site where she established her first world record by riding an equally-intimidating 68-foot wave....

September 11, 2020, marks the 19th anniversary of the most brazen and deadly terrorist attacks on American soil. The unprovoked act of violence, planned by Islamic extremist organization Al Qaeda, killed 2,977 innocent people and changed life as we knew it forever....

Marvel fans and movie enthusiasts worldwide are mourning the sudden death of Hollywood star Chadwick Boseman. The 43-year-old actor, best known for his portrayal of T'Challa — the king and protector of the fictional African nation of Wakanda in Black Panther — passed away on August 28, 2020, after a four year battle with colon cancer. The news came as a shock to most people since the intensely private Boseman, who was diagnosed at stage 3 cancer in 2016 — the year King T'Challa debuted in Captain America: Civil War — never spoke publicly about his illness....

Every summer, the Israel Antiquities Authority (IAA) invites teenage volunteers to work alongside archeologists at one of several dig sites across the country. The program, designed to provide the youth with an authentic archeology experience and to help them connect with Israel's history, usually results in the discovery of ancient tools or pottery. However, two teenagers at an excavation site in Yavneh, south of Tel Aviv, struck gold — literally— when they unearthed a clay jar filled with gold coins on August 18, 2020....

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....
