Study Notes

Florida Carpenter Ants: Life-Saving Surgeries

  • Florida carpenter ants exhibit a unique social behavior of performing life-saving "surgeries" on injured nestmates.
  • This behavior is unprecedented in non-human species.
  • These ants, native to the southern United States, often get injured defending their homes inside rotting wood.
  • Unlike other ant species, they lack antimicrobial substances to treat infected nestmates.
  • Researchers injured the legs of around 100 ants to study their response to battle-related injuries.
  • Injuries included cuts on the femur (upper leg) and tibia (lower leg), exposed to a common soil germ.
  • Injured ants in the nest received immediate attention from their mates, who cleaned the wounds.
  • Ants with femur injuries had their legs bitten off by their "doctors" in a 40-minute amputation process involving multiple ants.
  • Femur amputation resulted in a 90% survival rate, compared to 40% for isolated ants with femur injuries.
  • Tibia wounds were treated with a simple lick, resulting in a 75% survival rate, compared to 10% for isolated ants with tibia injuries.
  • Scientists believe treatment is linked to hemolymph flow; femur has more muscle tissue, slowing "blood" flow and allowing time for amputation.
  • Tibia has less muscle tissue, so infections spread faster, making cleaning the wound the preferred treatment.
  • According to Dr. Erik Frank, the ant's medical system can diagnose a wound and treat it accordingly.
  • Findings were published in Current Biology on July 2, 2024, with plans to explore similar behaviors in other ant species.

Elephants and Unique "Names"

  • Elephants possess exceptional intelligence, empathy, and communication skills.
  • Elephants assign individual "names" to each other, making them the first non-human species to exhibit this trait.
  • Elephants do not rely on imitation of calls to address one another like dolphins and parrots.
  • Dr. Joyce Poole observed elephants responding to specific calls while others ignored, suggesting names were being used.
  • Researchers analyzed over 600 recorded elephant calls collected over 30 years in Kenya's National Parks.
  • Machine learning tools correctly identified the receiving elephant's identity 28% of the time.
  • Elephants likely use names selectively, not in every interaction.
  • Playback experiments confirmed elephants reacted only to calls meant for them.
  • Elephants were more likely to use names over long distances or when calling to their calves.
  • The study was published in Nature Ecology and Evolution on June 10, 2024.
  • Dr. Pardo's team plans to investigate whether elephants also "name" other elements like food, water, and locations.

Charred Herculaneum Scrolls

  • Mount Vesuvius' eruption in 79 AD buried Pompeii and Herculaneum.
  • In 1752, over 1,800 charred papyrus scrolls were found in a Herculaneum mansion's library.
  • Scrolls' interiors were preserved due to a lack of oxygen during the charring process.
  • Researchers attempted to unfold the scrolls to gain insights into ancient life.
  • Mechanical unrolling led to the scrolls crumbling.
  • In 2009, Brent Seales developed X-ray technology to image the scrolls' interior non-invasively.
  • Scans revealed letters and some words, but visibility was limited by carbon-based ink blending with the papyrus.
  • Seales' team created an AI program to identify letters and symbols.
  • In March 2023, the "Vesuvius Challenge" invited students worldwide to help decode the scrolls using the AI program and 3D X-ray images.
  • Luke Farritor identified "porphyras," the Greek word for purple, becoming the first word decoded from the scrolls.
  • Youssef Nader independently found the same word, with the two sharing the "First Letters Prize".
  • Farritor, Nader, and Julian Schillinger teamed up to compete for the top prize.
  • The trio decoded 85% of the characters in four passages, and 15 partial columns (about 5% of the scroll).
  • The decoded passages were attributed to philosopher Philodemus, discussing the impact of abundant goods on joy.
  • Seales is challenging contestants to decode an entire scroll by the end of 2024, offering a $100,000 prize.

Description

Florida carpenter ants perform life-saving "surgeries" on injured nestmates. This behavior is unique as these ants amputate the legs of nestmates with femur injuries, leading to a 90% survival rate. This is compared to a 40% survival rate for isolated ants with femur injuries. They lack antimicrobial substances to treat infected nestmates.
