A new study sheds light on how the ancestors of modern land plants survived one of the most challenging aspects of life outside water: exposure to harmful ultraviolet (UV) radiation. By examining a microscopic alga closely related to the earliest land plants, researchers have unc

Sunburn is a serious problem in the Southern Hemisphere, where depleted ozone provides less protection from UVB. Tadpoles are at particular risk because they are growing rapidly, making them vulnerable to UVB DNA damage. Niclas Lundsgaard of The University of Queensland (UQ), Aus

Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. The issue is especially pertinent to the southeastern Un

Scientists have uncovered new evidence that fireworks can pollute both the air and water in ways that extend beyond the visible smoke. The findings show that leftover debris, fine particles, and airborne chemicals may affect ecosystems and increase people's exposure to air pollut

Bumblebees collect up to seven times the amount of toxic heavy metals as honeybees even when foraging in the same environment, new research from the University of Cambridge has found. Exposure to these metals can affect everything from their ability to forage for food to their ab

A next-generation pesticide designed to kill crop pests may also be interfering with the reproductive health of bumblebees. Researchers discovered that low-dose exposure to sulfoxaflor changed gene activity, especially in tissues involved in reproduction, raising concerns about l

Shielding astronauts from the deadly radiation they face is a central challenge for any designer of a deep-space crewed mission. Even relatively low levels of exposure over long periods can lead to everything from central nervous system damage to cancer. But current solutions, su

An unexpected study found that young non-smokers with healthier diets had higher rates of lung cancer, raising questions about whether pesticide exposure from conventionally grown produce could play a role. Researchers stress that the findings are preliminary and require further

Por Théo Costa Por muitos anos, a cibersegurança foi tratada como uma disciplina essencialmente técnica, focada na identificação de vulnerabilidades, implementação de ferramentas e resposta a incidentes. No entanto, o setor está passando por uma transformação estrutural. A segurança digital está se tornando uma área orientada por risco, contexto de negócio e capacidade de tomada de decis&a

As vulnerabilidades passaram a responder cerca de 40% das exposições críticas registradas em ambientes corporativos em 2026, mais que o dobro da proporção observada no ano anterior. Ainda assim, menos de um em cada 12 alertas exigia ação urgente. É o que mostra um levantamento da Check Point Software divulgado nesta quarta-feira (8) ao Canaltech. Segundo a empresa de cibersegurança, a pressão aumenta com ferramentas de ataque assistidas por IA, capazes de testar falhas conhecidas, c

Depois da reformulação do Samsung Health, mais um aplicativo da fabricante sul-coreana deve passar por uma renovação completa. Segundo informações do SammyGuru, o Galaxy Wearable — app para conexão com os relógios, fones de ouvido e outros acessórios inteligentes — receberá uma grande mudança visual, que deve chegar junto com o One UI 9 Watch. As imagens vazadas mostram uma interface reorganizada em três abas fixas na parte inferior da tela: Watch Faces, Home e Configurações do dispo
