Cientistas dizem ter descoberto por acaso órgão misterioso no centro da cabeça humana

As novas glândulas ficam atrás do nariz, no encontro com a garganta VALSTAR, ET. AL./RADIOTHERAPY AND ONCOLOGY

Uma equipe de pesquisadores na Holanda acredita que pode ter encontrado um novo conjunto de órgãos no corpo humano.

Eles identificaram o que acreditam ser novas glândulas localizadas atrás do nariz, no encontro com a garganta.

Os pesquisadores dizem que a descoberta provavelmente se trata de um quarto par de glândulas salivares (partes do corpo responsáveis por produzir saliva).

Se o achado for comprovado como verdadeiro, essa glândula oculta seria a primeira identificação desse tipo em cerca de 300 anos. Hoje conhecemos estas três principais glândulas salivares: uma inserida perto das orelhas, outra abaixo da mandíbula e outra sob a língua.

Os pesquisadores encontraram o que pode ser reconhecido como novas glândulas enquanto examinavam imagens em uma máquina capaz de mostrar tecidos corporais em detalhes.

Eles queriam saber mais sobre o que haviam encontrado, então examinaram um pouco de tecido. E descobriram que é muito semelhante às glândulas que temos sob a língua.

As possíveis novas glândulas foram encontradas no topo da garganta VALSTAR, ET. AL./RADIOTHERAPY AND ONCOLOGY

“O local não é muito acessível e você precisa de imagens muito sensíveis para detectá-lo”, disse Wouter Vogel, um dos autores do estudo.

Yvonne Mowery, oncologista de radiação na Duke University, disse que “ficou bastante chocada por estarmos em 2020 e ter uma nova estrutura identificada no corpo humano”.

Quão certos estão os cientistas sobre a descoberta?

A equipe de pesquisadores identificou as glândulas por acaso, já que estava focada em outros tratamentos quando as encontrou.

Na verdade, eles estavam examinando pacientes com câncer de próstata com um tipo avançado de exame, que, combinado com injeções de glicose radioativa, destaca tumores no corpo.

Assim, mais estudos serão feitos para determinar qual é exatamente o papel dessas glândulas — os médicos disseram que é preciso mais pesquisa e uma seleção mais ampla de pessoas.

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...
