Over the next two centuries dinosaur palaeontology would be dominated by numerous British natural scientists.

Key Points: 
  • Over the next two centuries dinosaur palaeontology would be dominated by numerous British natural scientists.
  • We present evidence that the first dinosaur bone may have been discovered in Africa as early as 500 years before Plot’s.
  • Peering through the published and unpublished archaeological, historical and palaeontological literature, we discovered that there has been interest in fossils in Africa for as long as there have been people on the continent.
  • More often than not, the first dinosaur fossils supposedly discovered by scientists were actually brought to their attention by local guides.

Bolahla rock shelter in Lesotho

  • One of the highlights of our paper is the archaeological site of Bolahla, a Later Stone Age rock shelter in Lesotho.
  • This part of Lesotho is particularly well known for delivering the species Massospondylus carinatus, a 4 to 6 metre, long-necked and small-headed dinosaur.
  • In 1990, archaeologists working at Bolahla discovered that a finger bone of Massospondylus, a fossil phalanx, had been transported to the cave.
  • Given the current knowledge, it could have been at any time of occupation of the shelter from the 12th to 18th centuries.

Early knowledge of extinct creatures

  • In Algeria, for example, people referred to some dinosaur footprints as belonging to the legendary “Roc bird”.
  • In North America, cave paintings depicting dinosaur footprints were painted by the Anasazi people between AD 1000 and 1200.

Claiming credit

  • For instance, unlike the people in Europe, the Americas and Asia, indigenous African palaeontologists seem to have seldom used fossils for traditional medicine.

Faith Kipyegon: from walking to school in rural Kenya to setting world athletics alight

All eyes are on Faith Kipyegon at the 2023 World Athletics Championships in Budapest, Hungary.

Key Points: 
  • All eyes are on Faith Kipyegon at the 2023 World Athletics Championships in Budapest, Hungary.
  • That’s because the Kenyan 1,500 metre and 5,000 metre star broke three world records in less than two months on her way to Hungary.
  • As expected, Ethiopia, Uganda and Kenya are spearheading Africa’s hopes for medals, continuing their dominance in middle and distance running events.

World record spree

    • She broke the 1,500m world record in June 2023 and just a week later stunned the stadium – and herself – by smashing the 5,000m world record.
    • Her season has simply been outstanding – also smashing the world record for the mile.

Who is Faith Kipyegon?

    • Like many kids educated in rural areas, she walked and jogged many miles to and from school.
    • Little did she know that this would instil the fundamental locomotion and physical skills that would form the foundation of her athletics career.
    • This walking is enhanced by the physical education and sports activities that children engage in while in school.
    • In the words of Kipyegon, winning that race created an awareness that she could “run fast and be a good athlete”.

Well deserved victories

    • During a recent speech she broke into tears, saying:
      Now I can buy my father a car.
    • I promised him when I was going to break a world record that I’m going to buy a car for him.
    • I promised him when I was going to break a world record that I’m going to buy a car for him.
    • Gold or no gold, world records or not, Kipyegon’s story is worth telling as she heads into the finals in Hungary.

Two of its clouds DR21 and W75N clearly have separate gas velocities, but which cloud is in front of the other, and whether or not the two clouds are colliding, are open questions.

Key Points: 
  • Two of its clouds DR21 and W75N clearly have separate gas velocities, but which cloud is in front of the other, and whether or not the two clouds are colliding, are open questions.
  • Dan Clemens, an astronomer at Boston University, is the principal investigator on a project using SOFIA to examine Cygnus-X and the effects of magnetic fields on its clouds and cloud filaments.
  • Most modern theories of star formation hint that magnetic fields may be channeling gas flows within molecular clouds toward a central hub, where massive star formation occurs.
  • The SOFIA observations will reveal the magnetic fields in filaments within the clouds, helping to verify the idea that fine, weak magnetic fields can control how stars form.
