Scientists have identified a critical breakdown in the cellular machinery that produces proteins in aging brains. Aging and neurodegenerative disease can interfere with a cell’s ability to produce properly functioning proteins. This process, known as “proteostasis,” or protein homeostasis, keeps مزید پڑھیں
Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown. The surface of Earth has a measurable size. Scientists can calculate its total area, and if the planet were مزید پڑھیں
Ancient DNA from Ajvide graves shows Stone Age burials often grouped extended relatives, highlighting the importance of wider kinship networks. One grave contained a young woman buried beside two small children who were not her own. In another burial, two مزید پڑھیں
A potential new mineral on Mars forms when iron sulfates are heated above 100°C. Data from Valles Marineris regions suggest geothermal processes altered ancient sulfate deposits. A study published in Nature Communications reports the discovery of an iron sulfate on مزید پڑھیں
Global warming may be speeding up—scientists say the planet is heating nearly twice as fast as before, putting the 1.5°C limit at risk before 2030. Global warming has been speeding up since around 2015, according to a new analysis from مزید پڑھیں
Regional wind patterns on Venus may stabilize mountain temperatures while generating dust storms that future landers must withstand. For decades, the surface of Venus has remained one of the least understood environments in the solar system. With only a handful مزید پڑھیں
A new study provides the first direct biological evidence explaining why some people continue to experience taste loss long after recovering from COVID-19. Researchers have uncovered specific biological changes in taste buds that could help explain why a small number مزید پڑھیں
Deep beneath Antarctica’s ice, scientists have uncovered a geological archive that could reshape predictions of future sea-level rise. Working roughly 700 kilometers from the closest Antarctic research stations, the team drilled through 523 meters of solid ice at Crary Ice مزید پڑھیں
Stepping into chilly air or tasting a mint sets off a specialized sensor in your body that signals the brain that something feels cold. Researchers have now obtained the first high-resolution images showing how this sensor works, revealing how it مزید پڑھیں
Why do some anti-glutamine therapies fail? A new study uncovers a hidden metabolic workaround involving pyruvate, biotin, and mutations in the FBXW7 gene. Scientists at the University of Lausanne have uncovered a cellular mechanism that reveals a hidden weakness in مزید پڑھیں
