Artificial light is a deadly siren song for y | EurekAlert! - 0 views

  • News Release 3-Jul-2024 Artificial light is a deadly siren song for young fish Reports and Proceedings Society for Experimental Biology image: Light pollution at night over aquatic habitats in French Polynesia. view more  Credit: Jules Schligler New research finds that artificial light at night (ALAN) attracts larval fish away from naturally lit habitats, while dramatically lowering their chances of survival in an “ecological trap”, with serious consequences for fish conservation and fishing stock management.

Wear it, then recycle: Designers make dissolvable textiles from gelatin | ScienceDaily - 0 views

  • A T-shirt that you can wear a few times, then, when you get bored with it, dissolve and recycle to make a new shirt.

Does this wolf want to play-or attack? Take a close look at its face | Science | AAAS - 0 views

  • Many contemporary studies have used methods designed to study dogs—a poor proxy, as our furry friends have fewer facial expressions than their ancestors.
  • (These techniques have previously been used to study facial expressions in cats.)
  • These expressions were common to all of the gray, arctic, and Canadian wolf packs the researchers observed.

Odors are encoded in rings in the brain of migratory locusts | ScienceDaily - 0 views

  • However, this coding mechanism is not necessarily transferable to other locust species.

Ants perform life saving operations - the only animal other than humans known to do so ... - 0 views

  • In experiments, they observed that the ants treated their nest members' femur injuries by cleaning the wound with their mouths before amputating the leg by repeatedly biting it, while the tibia wounds were treated with just cleaning.
    • Kylie John
       
      I wonder how the ant functions after this. It mentions that later the survival rate goes up but is the ant still able to do everything it used to? Like how ants can carry a lot more than their body weight, does that change for the ant after it got amputated?
  • The scientists are now extending their research to other ant species that don't possess special antimicrobial glands to see if other ants have the ability to perform surgeries.

A high-fat diet may fuel anxiety | ScienceDaily - 0 views

  • The study found that in animals, a high-fat diet disrupts resident gut bacteria, alters behavior and, through a complex pathway connecting the gut to the brain, influences brain chemicals in ways that fuel anxiety.
  • "To think that just a high-fat diet could alter expression of these genes in the brain is extraordinary," said Lowry. "The high-fat group essentially had the molecular signature of a high anxiety state in their brain."

A new path to new drugs: Finding alternatives to animal testing | Science | AAAS - 0 views

  • For example, researchers studying vitiligo, an autoimmune skin disorder, can directly assess how a potential intervention impacts autoimmune processes in skin tissue derived from people with vitiligo.

Frontiers | Evaluating undesired scratching in domestic cats: a multifactorial approach... - 0 views

  • cratching serves many purposes such as maintaining claw health, provision of safety by marking and social communication
  • This holistic approach ensures a comprehensive understanding and effective management of scratching-related issues in domestic cats.

What causes you to get a 'stitch in your side'? | Live Science - 0 views

  • This theory is supported by the fact that side stitches become more likely if you eat or drink right before exercise.
    • Kylie John
       
      Does this mean that if I don't eat before I run I won't get a side stitch because I would appreciate that

World's largest hummingbird is actually two species | ScienceDaily - 0 views

  • "They are as different from each other as chimpanzees are from bonobos,"
    • Kylie John
       
      The article does not go into any more depth about the behavioural differences the two birds have. I wish it did.

Extreme solar storm generated aurorae-and 'surprise' | Science | AAAS - 0 views

  • Although this weekend’s storm didn’t appear to take out any satellites, it may shorten some of their life spans.

      I just find it interesting that these solar storms effect satellites

Nature's 3D printer: Bristle worms form bristles piece by piece | ScienceDaily - 1 views

  • Nature's 3D printer: Bristle worms form bristles piece by piece
  • The Raible group is currently working on improving the resolution of the observation in order to reveal even more details about bristle biogenesis.

Source reservoir controls on the size, frequency, and composition of large-scale volcan... - 0 views

  • Fig. 1. Source reservoir processes that may supply a large volcanic eruption.

      How did they figure out what caused the volcanos to erupt? Can you see how a specific volcano erupted based off of that?
  • Development of buoyancy overpressure at the top of a magma layer
  • Rayleigh-Taylor instabilities develop naturally whenever buoyant magma layers form.

Dams trigger exponential population declines of migratory fish | Science Advances - 0 views

  • When the GD, the first dam across the mainstream of the Yangtze River, was built in the 1970s, the Chinese government explicitly demanded that the dam consider the conservation of fish.
  • Dams can harm migratory fish by disrupting their life cycles and then causing population extinctions.
    • Kylie John
       
      Is it possible to give the fish a different area to migrate to and from?
  • We divide the species population into spawning stock (spawners), which are sexually mature adults participating in the current year’s breeding, and recruitment stock, which includes larvae, juveniles, and subadults that have not reached the reproductive age and sexually immature adults/post-spawners that do not participate in the current year’s breeding.
  • ...2 more annotations...
  • The sixth misjudgment concerns the assertion that fishways are unnecessary in dams. The 1982 GD-FRP suggested that fishways were not needed for the Chinese sturgeon (14). The TGD, built in 1993, followed this idea and did not include fishways.
  • This study has certain limitations, such as the need for larger sample sizes of fish to improve the accuracy of the precision of fish life cycle models.
