Phys.org / When mitochondria grow abnormally long, leaked RNA may activate anti-tumor immune responses
Researchers from the University of Osaka have demonstrated that mitochondrial hyperfusion, when induced by low levels of DRP1 or cellular stress, activates an immune response through the RIG-I–MAVS pathway. Dependent on the ...
Phys.org / There may be 3 times more insect species than previously thought
A new estimate of insect species globally finds that there may be 8 million to 14 million more species than people thought, with few of them discovered.
Tech Xplore / Short training helps people spot AI faces in the battle against deepfake fraud
Humans have been successfully trained to spot AI-generated faces in a study led by researchers at the Australian National University (ANU) Emotions and Faces Lab. The study, "Training Humans to Detect AI-generated Faces," ...
Medical Xpress / Unlocking diabetes' secrets: Pediatric organ donors help map a path to a cure and prevention
The autoimmunity associated with type 1 diabetes often begins in the first years of life, and the diagnosis of type 2 diabetes is rapidly rising among children and teens.
Phys.org / Ultra-faint galaxy discovered near Andromeda may be 12.5 billion years old
A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the galaxy, named And XXXVI, ...
Phys.org / Why Europe's rising plant diversity may signal habitat disruption, not ecological recovery
The number of plant species in many ecosystems in Europe has grown rather than shrunk over the last 100 years. However, this is not necessarily cause for celebration, as this local increase is primarily due to generalists ...
Phys.org / Ozone depletion began decades before discovery of ozone hole, scientists find
The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs), then widely used as ...
Phys.org / A goat's tooth may have solved a 100‑year debate about ancient Greek farming
The agricultural economy was the backbone of wealth in ancient Greece. Food brought people together, whether in smaller groups at a wine-drinking symposium or the entire community in a sacrificial feast of epic proportions. ...
Phys.org / Could AI create a new form of inequality in South Africa?
Generative artificial intelligence (AI), especially large language models deployed as chatbots and digital assistants, are now part of everyday digital life.
Phys.org / NASA launches robot to rescue aging Swift telescope from fiery demise
NASA on Tuesday is set to launch a daring robotic rescue mission, a long-shot bid to prevent one of its aging telescopes from vanishing into dust.
Phys.org / The rise of space AI might explain the Fermi paradox
Artificial intelligence (AI) is continuing to have a disruptive impact on ever more parts of humanity. But what does it mean in the long run? A new paper, available as a preprint on arXiv from Austrian researcher Sergey Ivliev, ...
Phys.org / Synthetic chemical framework can switch magnetic spin states at near ambient temperatures
There is growing demand for smart materials that can change their physical properties in response to various external stimuli such as light, heat, pressure, magnetic fields and electric fields. One such physical property ...
