    Historic Plant Remains Found in Kenya Reveal Agricultural Origins

    In a groundbreaking study, ancient plant remains have been discovered near Lake Victoria in Kenya, offering new insights into early farming practices in equatorial eastern Africa. This exciting discovery confirms the long-held belief that this region was crucial for early agriculture, even though there was previously no physical evidence of ancient crops.

    Archaeologists and academics from various institutions collaborated to create the most extensive and well-dated archaeobotanical record from interior East Africa. This region had not previously yielded ancient plant remains. The research clarifies the origins of early plant farming in Kenya, Tanzania, and Uganda, a vast and diverse area.

    “There are many stories about how agriculture began in East Africa, but not much direct evidence of the plants themselves,” said Natalie Mueller, an assistant professor of archaeology at Washington University in St. Louis. At Kakapel Rockshelter, Mueller and her team found an extensive collection of plant remains, including many crops.

    This historical discovery highlights a history of diverse and adaptable farming systems, challenging stereotypes about Africa. Of particular importance are the cowpea remains found at Kakapel, dating back 2,300 years. Cowpea, thought to have originated in West Africa, marks the earliest known arrival of a domesticated crop in eastern Africa.

    “Our findings at Kakapel reveal the earliest evidence of domesticated crops in east Africa, showing the interactions between local herders and incoming Bantu-speaking farmers,” noted Emmanuel Ndiema from the National Museums of Kenya.

    Located near the Kenya-Uganda border, north of Lake Victoria, Kakapel Rockshelter is a nationally recognized archaeological site. Its rich deposits span over 9,000 years of human occupation, offering unique insights into the evolution of human societies.

    “Kakapel Rockshelter is one of the few sites in the region where we can see such a long sequence of occupation by diverse communities,” said Steven T. Goldstein, an anthropological archaeologist at the University of Pittsburgh. The research is significant for various fields, including historical linguistics, plant science, genetics, African history, and domestication studies.

    The Milky Way’s Origins: Advances in Galaxy Formation Research

    Astronomers are using powerful computers to simulate how galaxies formed from the Big Bang until now, 13.8 billion years later. These simulations have some errors. To fix them, a team of researchers from Lund University and other institutions spent eight years and a lot of time.

    Galaxy Formation

    In the past ten years, there have been massive improvements in computer simulations that can show how galaxies form. These simulations are very important for understanding where galaxies, stars, and planets come from. But sometimes, the predictions from these simulations have mistakes because the computers cannot show everything perfectly.

    To make better simulations, 160 researchers from 60 universities worked together. They compared their simulations and looked for mistakes. The leaders of this project are Santi Roca-Fàbrega from Lund University, Ji-hoon Kim from Seoul National University, and Joel R. Primack from the University of California.

    They found out that the gas around galaxies is more important than the number of stars in the galaxy. This is different from what people used to think. This project took eight years and used a lot of computer time. But the researchers are happy with what they found.

    They published three papers in The Astrophysical Journal about their work. They looked at how a galaxy the same size as the Milky Way formed. They used the same ideas about stars, gas, and light as other simulations. Their new results show that galaxies like the Milky Way formed early in the universe’s history. They also solved a problem about small galaxies going around bigger ones.

    They want to keep working to make even better simulations of galaxy formation. With better simulations, they hope to learn more about our galaxy, the Milky Way. This is just the beginning of understanding how galaxies form.

  • Origins of ‘SOS’: From Morse Code to Distress Call

    Origins of ‘SOS’: From Morse Code to Distress Call

    “SOS” is a well-known distress signal, but it doesn’t stand for anything specific, like “save our souls” or “save our ship.” These are actually made-up phrases for the acronym. In reality, “SOS” is a continuous Morse code sequence of three dots, three dashes, and three dots without any spaces (…—…). However, people began using “SOS” because three dots represent the letter S, and three dashes represent the letter O in the International Morse Code.

    SOS

    This Morse code sequence has become a recognized visual distress signal on its own, and people in need of help often spell out “SOS” on the ground to be seen from above. If you break down the Morse code sequence, you can also interpret it as IJS, SMB, or VTB.

    So, why use this specific sequence of dots and dashes if it doesn’t have a meaning? The reason is that it was the best way to communicate distress when wireless radiotelegraph machines were first used on ships around the early 1900s.

    In those early days, sailors needed a way to quickly and clearly signal distress and ask for help. Different organizations and countries had their own distress signals, which caused confusion and language barriers when ships were in trouble in foreign waters. For example, the U.S. Navy used “NC,” the Marconi Company used “CQD,” and Germany used “…—….”

    International regulations for radiotelegraph communications were established in 1906 during the International Wireless Telegraph Convention in Berlin to address this issue and create a universal distress signal. After considering various options, Germany’s “…—…” was chosen as the international distress signal because it could be transmitted rapidly and clearly without confusion. This standard went into effect on July 1, 1908.

    The first recorded use of “SOS” as a distress signal happened in August 1909 when the SS Arapahoe’s wireless operators sent the signal after the ship’s propeller broke off the coast of Cape Hatteras, North Carolina. Not everyone immediately adopted the new standard. The Marconi Company was hesitant to give up “CQD.” In fact, during the sinking of the Titanic, Marconi operators initially sent “CQD” before eventually using “SOS” as well.
