Researchers analyzed DNA from hairs in the teeth of the infamous Tsavo man-eating lions, revealing that they consumed a diverse range of animals including giraffes and humans. The analysis indicated that the lions were siblings with a genetic makeup typical of Kenyan or Tanzanian lions. The Terror of Tsavo In 1898, two massive, maneless male...
Nuclear energy is often promoted as a cleaner alternative to fossil fuels because it doesn’t emit carbon dioxide. However, one major obstacle shadows its potential: the management of radioactive waste. With the growing number of nuclear reactors globally, the accumulation of this hazardous byproduct poses a significant environmental and public...
Recent advances in molecular biology have provided unprecedented insights into the structure of amyloid fibrils associated with Huntington’s disease (HD). By integrating experimental methods such as cryogenic electron microscopy (cryo-EM) and solid-state nuclear magnetic resonance (ssNMR), researchers are unraveling the complex architecture of protein aggregates that contribute to neurodegenerative disorders....
Pterosaurs were the first vertebrates to achieve powered flight, but they remain the only major volant group to face extinction. Despite their significance, much about their flight mechanics has been elusive due to the rarity of well-preserved fossils. Recent discoveries in Jordan, however, have shed light on this mystery, offering...
