    Readers respond to Lyme disease, fossil teeth and a Tesseract look-alike

    Lyme light

    Lyme disease is hard to detect, but scientists are investigating new diagnostic approaches that could help people get treated for the tickborne illness sooner, Laura Beil reported in “New approaches may help solve the Lyme disease diagnosis dilemma” (SN: 6/22/19, p. 22).

    “I found the info in a recent issue about better ways to detect Lyme disease to be very interesting,”...

    Ancient Maya warfare flared up surprisingly early

    In 697, flames engulfed the Maya city of Witzna. Attackers from a nearby kingdom in what’s now Guatemala set fires that scorched stone buildings and destroyed wooden structures. Many residents fled the scene and never returned.       

    This surprisingly early instance of highly destructive Maya warfare has come to light thanks to a combination of sediment core data, site excavations and...

    Satellites are transforming how archaeologists study the past

    Archaeology from SpaceSarah ParcakHenry Holt and Co., $30

    The term “space archaeology” may conjure up images of astronauts hunting for artifacts from little green men, but the field is much more down to Earth. Space archaeologists use satellite imagery and other remote-sensing techniques to look for ancient sites on our planet. As archaeologist Sarah Parcak explains in her new book...

    Readers inquire about measles, vaccine hesitancy and more

    Tough choices

    Discussing shared health goals with vaccine-hesitant parents may help doctors get those parents on board, Aimee Cunningham reported in “Finding common ground can reduce parents’ hesitation about vaccines” (SN: 6/8/19, p. 16).

    Reader Dona Chilcoat objected to a photo in the story that showed a crying baby getting a shot. She thought the image might help reinforce anti-­...

    A Greek skull may belong to the oldest human found outside of Africa

    A skull found in a cliffside cave on Greece’s southern coast in 1978 represents the oldest Homo sapiens fossil outside Africa, scientists say.  

    That skull, from an individual who lived at least 210,000 years ago, was encased in rock that also held a Neandertal skull dating to at least 170,000 years ago, contends a team led by paleoanthropologist Katerina Harvati of the University of...

    Ancient humans used the moon as a calendar in the sky

    The sun’s rhythm may have set the pace of each day, but when early humans needed a way to keep time beyond a single day and night, they looked to a second light in the sky. The moon was one of humankind’s first timepieces long before the first written language, before the earliest organized cities and well before structured religions. The moon’s face changes nightly and with the regularity of...

    Ancient DNA reveals the origins of the Philistines

    Hard-won genetic clues from the bones of Philistines, a people known from the Old Testament for their battles with Israelites, have taken some of the mystery out of their hazy origins.

    DNA extracted from the remains of 10 individuals buried at Ashkelon, an ancient Philistine port city in Israel, displays molecular links to ancient and modern populations in the eastern Mediterranean,...

    East Asians may have been reshaping their skulls 12,000 years ago

    Ancient tombs in China have produced what may be some of the oldest known human skulls to be intentionally reshaped.

    At a site called Houtaomuga, scientists unearthed 25 skeletons dating to between around 12,000 years ago and 5,000 years ago. Of those, 11 featured skulls with artificially elongated braincases and flattened bones at the front and back of the head, says a team led by...

    Hominids may have been cutting-edge tool makers 2.6 million years ago

    Discoveries in East Africa of what may be the oldest expertly sharpened stone implements suggest that early members of the human genus, Homo, invented these tools by around 2.6 million years ago, researchers say. But their conclusions are controversial.

    New finds at a site in Ethiopia called Ledi-Geraru fit a scenario in which various early Homo groups devised ways to sharpen handheld...

    Africa’s first herders spread pastoralism by mating with foragers

    Ancient sheep, goat and cattle herders made Africa their home by hooking up with the continent’s native hunter-gatherers, a study suggests.

    DNA analysis shows that African herders and foragers mated with each other in two phases, says a team led by archaeologist Mary Prendergast of Saint Louis University in Madrid. After entering northeastern Africa from the Middle East around 8,000...
