Lightning, Gamma-Ray Flash Link Discovered in Japan
Researchers in Japan linked a lightning strike to a terrestrial gamma-ray flash using ground-based sensors, revealing details of the collision of lightning leaders and electron acceleration.
Cosmic Rays: Supernova Explosions & Powerful Energies
Cosmic rays, mainly protons, are accelerated by supernova explosions. These high-energy particles, sometimes exceeding PeV, interact with Earth's atmosphere and surface. Supernova remnants are key PeVatron candidates.
CJD: Growth Hormone Therapy Link & Prion Disease
Case study links growth hormone therapy to Creutzfeldt-Jakob Disease (CJD). Prions from cadaver-derived hormones caused a fatal neurological condition. Long latency period is a concern.
Adam Kovalčík: Cheaper Antivirals & RNA Virus Breakthrough
Adam Kovalčík pioneers a lower-cost method to produce antivirals like galidesivir, targeting RNA viruses (Ebola, Zika). Using corn husks, his process simplifies drug creation, potentially saving lives. COVID-19 impacts.
Orcas & Pilot Whales: Unusual Interactions in Iceland
Orcas and infant pilot whales interact annually off Iceland (2021-2023). Possible explanations include parenting, predation, or play. Researchers observed unique echelon positioning & temporary encounters. Environment change might also play a role.
Ancient Tsunamis: Amber as Evidence of Past Tidal Waves
Researchers explore amber deposits to uncover evidence of ancient tsunamis dating back 12,000 years. Amber 'fire structures' suggest rapid sediment deposition, potentially caused by tidal waves.
Orange Cat Genetics: Scientists Solve the Mystery!
Scientists have cracked the genetic code behind orange cats! A mutation in the ARHGAP36 gene, located on the X chromosome, determines if a cat will have orange fur and explains why most orange cats are male.
Ancient Mars: Water Sea, Coastline & Ferrihydrite Mineral
Evidence suggests Mars may have had a water sea 3.6 billion years ago. The Zhurong rover found a possible ancient coastline. Ferrihydrite mineral required cold, wet conditions, influencing Mars' rusty color.
Longevity Genes: Immunity, DNA Repair & Lifespan in Mammals
Study links longevity in mammals to immunity genes & DNA repair. Gene duplication plays a role in lifespan variation. Research on resistance genes might lead to anti-aging therapies.
Mono, Genes & MS Risk: New Insights
Study links HLA-E gene, mono & MS risk. Individuals with HLA-E * 01:01 gene & mono history show higher MS likelihood. Early detection & treatment implications are crucial for long-term health.
Identifying Stone Tools: A Flintknapper’s Guide
Learn how to identify hominin stone tools by understanding flake marks, flintknapping techniques, rock context, and fracture patterns. Essential insights from a seasoned archaeologist.
Surveillance & Mental Health: How Being Watched Affects Our Brains
Constant surveillance, even subconscious, affects our brains, impacting attention, memory, and social processing. Studies show being watched can trigger fight-or-flight responses and cognitive exhaustion. Mental health concerns arise.
