Radiação de celulares contribui para morte de insetos, afirma estudo

Redes sem fio dificultam navegação de animais e deterioram células Pixabay

Um estudo mostrou que a radiação de telefones celulares está contribuindo para o rápido declínio de insetos nos últimos anos. A pesquisa, feita pela Nabu (Nature and Biodiversity Conservation Union), analisou outros 190 estudos cientifícos e foi apresentada nesta quinta-feira (17).

Ao menos 72 estudos analisados mostraram que a radiação impactou negativamente espécies como vespas, abelhas e moscas. Os efeitos principais são dificuldades de navegação por causa de perturbações de campos magnéticos e dano ao material genético de larvas.

A pesquisa mostrou que a radiação emitida por smartphones e sinais Wi-Fi causam uma ionização das células dos insetos, o que diminui a capacidade de reprodução e causa declínio das capacidades imunológicas dessas espécies.

A radiação age em conjunto com outros fatores para causar o declínio dramático de populações de insetos, como destruição de habitat e uso descontrolado de pesticidas. O estudo focou nos efeitos no continente europeu, mas cenários parecidos são observados em todos os outros continentes.

“O assunto é incômodo para muitos de nós, porque interfere em nossos hábitos diários e há interesses econômicos poderosos por trás da tecnologia de comunicação móvel”, afirmou Johannes Enssle, diretor regional do NABU, ao site Phys.org.

Um estudo alemão, publicado em 2019 pela revista Nature, afirmou que as populações de artrópodes (o que inclui também aracnídeos, crustáceos e espécies de centopeias) diminuiu cerca de 67% nas pastagens europeias e 41% nas florestas do continente.

O estudo da Nabu ainda precisa ser revisado por especialistas, antes de ser publicado em um periódico científico.

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...
