A study reveals how the tapeworm Anomotaenia brevis extends the lifespan of Temnothorax nylanderi worker ants. The parasite alters the ant's gene expression, making its fat body resemble that of a long-lived queen, while dampening brain activity to reduce work and increase survival for the parasite's life cycle.
A study reveals how the tapeworm Anomotaenia brevis extends the lifespan of Temnothorax nylanderi worker ants in Germany. The parasite alters ant gene expression, making their fat bodies queen-like for longevity, while dampening brain activity for a quieter, lazier existence, aiding its own life cycle.
Science explains why siblings raised in the same home develop distinct personalities. Differences stem from genetics, non-shared environmental experiences, sibling interactions, external influences like friends, birth order, and chance.
荷蘭一項研究發現，特定基因變異可能與人類更健康長壽有關。研究分析了212個長壽家族的基因體資料，找出12種罕見的基因變異，其中涉及CGAS基因的變異尤其引人注目，可能透過降低發炎反應來延長健康壽命。
Tom Hutchins, a 30-year-old business director in Hong Kong, was diagnosed with testicular cancer after noticing a small dot, not a lump. Early detection and his girlfriend's encouragement led to prompt medical attention, mitigating the shock of the diagnosis.
Researchers have created tiny, self-replicating blobs using lab-made DNA. These blobs can feed, grow, and multiply in a dish, marking a significant step towards creating life from non-living matter. The development is discussed by experts in the field.
Rowan Hooper's "Togetherness" challenges Darwin's emphasis on competition, highlighting the crucial role of cooperation and symbiosis in nature. The book argues that understanding these interdependencies is vital for conservation efforts.
Scientists have developed a new non-invasive maternal blood test, NIFS, capable of detecting thousands of serious genetic conditions in a fetus. This advanced sequencing technique identifies fetal DNA fragments in the mother's blood, potentially replacing invasive procedures like amniocentesis and offering earlier diagnosis for a wider range of disorders.
Dutch firm Floricultura uses genetic markers to accelerate orchid breeding, predicting traits like color and disease resistance, reducing wait times from 3 years, while human judgment remains crucial for final selection based on beauty.
Colossal Biosciences, a Dallas-based biotech startup backed by the CIA and Peter Thiel, has announced a new de-extinction project for the bluebuck, an extinct South African antelope. The project represents a strategic shift, with CEO Ben Lamm emphasizing that the reproductive technologies developed will be open-sourced for conservation. However, the company continues to face criticism from ecologists who argue that flashy de-extinction announcements distract from efforts to save critically endangered species that still exist.
