A teeny device can measure subtle shifts in Earth's gravitational field - 0 views

  • Called gravimeters, such devices can detect tectonic plates shifting, sense the movement of underground water, reveal hidden oil and gas reserves, and track magma within volcanoes to provide data for predicting eruptions, along with many other applications.

      How is a Gravimeter able to detect the movement of tectonic plates shifting, does it detect sound waves or vibrations?

Model Organisms - HSR 2025 - Google Docs - 3 views

  •  
    This is a crowd-sourced document I created for a session with high school research teachers in Washington D.C. in 2022. SAVE this document and use it to explore some of the more commonly-used model organisms for all sorts of biological research. There is a TON to explore here!

Model Organisms for Research - HSRTC - 2022 - Google Slides - 4 views

  •  
    This is a slide deck I used for a presentation to research teachers in Washington D.C. last year. I will also save a link to the crowd-sourced document we created in this session where teachers too our suggested model organisms, and then added in their suggestions as well.

Do Invertebrates Have Emotions? | The Scientist Magazine® - 1 views

  • He adds that he doubts that the findings are applicable to other insect species, which still might act purely on instinct.
  • Invertebrate nervous systems, physiology, and sensory experiences are dissimilar to ours, and designing experiments to measure their emotions has been challenging. 
  • If the responses weren’t purely reflexive, it would open up the possibility that the animals could feel pain.

  • After placing acetic acid—a mild irritant—on the crabs’ antennae, they found that the crabs rubbed their antennae against the glass of their aquarium, seemingly in an attempt to take the acid off.

      The use of an invisible irritant rather than a notable injury shows that they can feel the pain, instead of just noticing an injury to their body.

Stony coral tissue loss disease indirectly alters reef communities | Science Advances - 2 views

  • Butterflyfishes, which are facultative corallivores in this region, have even been found to prefer SCTLD-infected coral

      Some species like the infected coral Maybe it has different properties or something
  •  
    You know, there are repositories of publicly available image/video data from coral reef surveys.... somewhere online. They make them available for people to devise creative ways of pulling data out of such raw material. Might be something to look into.

Control of behavioral decisions is similar in insects and mammals | ScienceDaily - 2 views

  •  
    I wonder what sort of electronics were needed to accomplish this. I also wonder how difficult it would be to attach those to a living insect without sacrificing it.

Bumblebees use Lego blocks to build science and recognise the value of teamwork | Unive... - 1 views

  •  
    Interesting. The video clips are especially valuable for understanding their methods. So, these tests have been done... but what other sorts of learning tests might be possible? Are there any that might even show value in this species beyond just "what is possible for the bee nervous system to accomplish?"

What the Heck Is Seaweed Mining? | Hakai Magazine - 6 views

  • “It’s pure chemistry,” Umanzor says. “Positive with negative, and then it just collects.”

      For those interested in chamistry topics, this looks really interesting.
