In February 2023, the family of actor Bruce Willis made an announcement about his health. The previous year, Willis had been diagnosed with aphasia, a disorder that prevents a person from speaking or understanding speech. As his condition worsened, physicians identified Bruce Willis has frontotemporal dementia. Frontotemporal dementia is one of four main types of dementia. About 50 million people worldwide are living with dementia, and epidemiologists expect that number to triple by 2050. Ab ...read more
Yes, there is a hypothetical particle, called the tachyon, that could travel back in time. One catch: It almost certainly doesn’t exist. Time and Speed of Light Before we start talking about time travel, we first must talk about the speed of light. All objects in our universe are constrained to go no faster than the speed of light. The only particles capable of achieving light speed are massless particles, like light itself. Anything with even a tiny amount of mass will find it impossible to a ...read more
Archaeologists working in a seafront cave in Portugal have discovered the remains of various shellfish, including numerous brown crabs, where Neanderthals lived around 90,000 years ago. The finding suggests that Neanderthals were cooking and eating crab and shellfish meat. More specifically, according to the new study published in Frontiers in Environmental Archaeology, the Neanderthals living on the Iberian Peninsula hunted and ate mostly larger adult crabs. This suggests Neanderthals knew larg ...read more
Exploring inside of our planet like we explore the solar system is a frontier that may be reached. The intense pressure and temperature in the Earth makes it nearly impossible to even conceive of how we could explore much of our planet with our own eyes. That doesn't mean we don't know a lot about the inner workings of Earth, but it takes some circumstantial evidence to pull it off. If we were to travel from the surface of the Earth to the very middle, we'd travel nearly 4,000 miles. Although th ...read more
Ancient tools, buried for millions of years in Kenya, may be the oldest example yet of our ancestors’ technological prowess. The tools, recently discvered on the Homa Peninsula in Lake Victoria, are now the earliest known examples of Oldowan technology — stretching its known start date back by as many as 400,000 years. The Oldowan Toolkit “[Oldowan] is a real benchmark of our technology,” says paleontologist Rick Potts, the director of the Human Origins Program at the Smithsonian Nationa ...read more
