Esqueleto bem preservado de mamute é encontrado na Rússia

Cientistas russos estão debruçados sobre os ossos espantosamente bem preservados de um mamute adulto que percorria a Terra há pelo menos 10.000 anos, depois que habitantes locais descobriram seus restos mortais nas águas rasas de um lago na Sibéria.

Parte do crânio, várias costelas e ossos da parte dianteira, alguns com tecidos moles ainda presos a eles, foram recuperados da remota península russa de Yamal, acima do círculo Ártico, em 23 de julho. Os cientistas ainda estão procurando outros ossos no local.

Achados semelhantes na vasta região da Sibéria, região da Rússia, acontecem com regularidade cada vez maior, pois as mudanças climáticas aquecem o Ártico a um ritmo mais rápido do que o restante do mundo derrete o solo em algumas áreas há muito tempo bloqueadas pelo permafrost.

Cientistas divulgaram imagens em dezembro de um filhote de cachorro pré-histórico, que teria 18.000 anos, encontrado na região do permafrost do Extremo Oriente da Rússia em 2018.

Os restos de mamute têm pelo menos 10.000 anos, embora os pesquisadores ainda não saibam exatamente quando andou na Terra ou quantos anos tinha quando morreu, disse Dmitry Frolov, diretor do Centro Científico para Estudos do Ártico.

Pesquisadores descobriram fósseis de mamutes datados de até 30.000 anos atrás na Rússia, afirmou ele.

Yevgeniya Khozyainova, cientista de um museu local, disse que é incomum encontrar tantos ossos pertencentes a uma única espécie e saber de onde eles vieram.

“É claro que gostaríamos de encontrar as partes restantes, para entender o quão completo é esse achado. Sempre que resta tecido mole, é um material valioso para estudar”, declarou ela.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
