      They had to use scanning electron microscopy to figure this out, yes. BUT... in scaling something like this up, we would not need such a thing!
  • The refractive index tomograms of isolated bristles were obtained by Nanolive 3D Cell Explorer, and raw data were deposited at https://doi.org/10.5281/zenodo.10207240.

      This might be the way to dial in the measurement ratios to mimick something like this on a larger scale for some purpose. How do the worms use them? If this doesn't get it, we can ALWAYS email the actual scientists to see if they can send us this data to do what we're trying to do. They are usually VERY helpful in such things for creative and hard-working students.

    I am often thinking about biomimicry. I wonder if something like this process could be 3D printed at a larger scale... for another valuable use of some sort. (?)
  • Sean Nash on 16 May 24
     
    This one is a LOT of chew through, but it is super interesting to figure out how living things bioengineer such structures over millions of years of evolution. Biomimicry is simply us studying (and then mimicking) the most interesting things in nature... to enhance something in the human world. This article is the original journal article linked to and highlighted by one of the ScienceDaily stories from today.

  • The experts selected onion plants to test out this idea, known for their high sensitivity to toxins in the environment. In beakers of water containing bentazone, they grew onion root tissue, called meristems, measuring its cell division and root growth as a sign of health.

      One of the things I want VERY badly for our program... is a set of equipment for histology... where we can take things like onion root tips and lock samples in wax, slice them incredibly thin (microslices), and then be able to mount them onto slides for analysis.

  • Rho's work is grounded in a social science framework called Fuzzy Trace Theory that was pioneered by Valerie Reyna, a Cornell University professor of psychology and a collaborator on this Virginia Tech project. Reyna has shown that individuals learn and recall information better when it is expressed in a cause and effect relationship, and not just as rote information. This holds true even if the information is inaccurate or the implied connection is weak. Reyna calls this cause-and-effect construction a "gist."

      Fuzzy Trace Theory looks interesting for this, and perhaps many other reasons. I want to learn more about this myself, and I'm wondering if this theory could be put to work in other potential behavioral science projects. What do you think?

  • 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.

  • 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.

    Just a SUPER basic overview of phytohormones. The + is that we can obtain ALL of these for use in pure form. The - is that you need to develop a unique question/experimental design.

    Be sure you are tagging articles when you bookmark them. I don't see any tags on this one, and I only see one on the other, "ice." Also... this is a SUPER interesting topic. However, we'd have way more than an uphill climb working with any sort of known pathogens (even potential pathogens) if we could even get our hands on them.

  • fish feed. The wastewater from soybean
  • processing can be converted into a nourishing, protein-rich food for farmed Asian sea bass, a team of scientists has discovered.
  • They worked with a local food processing company to rescue hundreds of liters of soybean wastewater, which they discovered was rich in two types of protein-accumulating microbes in particular, known as Acidipropionibacterium and Propioniciclava.
  • ...3 more annotations...
  • The sea bass that were fed the alternative microbe protein diet did have significantly lower weight to begin with, but that evened out as they grew. And, notably, the group that received the traditional feed diet had greater variability in their weight gain as they grew—whereas those fed the alternative microbe protein diet showed a more even accumulation of weight over the experiment’s course.
  • Meanwhile, the wastewater from other soybean uses goes unused—but according to the recent results, could feasibly tackle both of these sustainability challenges at once. Furthermore it’s not just soybean waste water, the researchers say: several agricultural processes create wastewater side streams that are rich in the combination of carbon, nitrogen, and phosphorus that’s needed to sustain a growing population of hungry, protein-accumulating bacteria.
  • Microbial community‐based protein from soybean‐processing wastewater as a sustainable alternative fish feed ingredient.

    Possible more efficient fish feed to reduce waste and benefit the environment as well as the economy.
