OK- so THIS specific thing is done. I have not seen the data (decibels @ 50') but I do know this... there are many other challenges unsolved (and largely unaddressed) out there.
Dynamic microvilli sculpt bristles at nanometric scale | Nature Communications - 0 views

-
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. (?)
-
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.

Add to the many afterlives of coffee grounds: Toxic cleanup - 0 views
-
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.

Study traces an infectious language epidemic | ScienceDaily - 0 views

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?

How did they figure out what caused the volcanos to erupt? Can you see how a specific volcano erupted based off of that?

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.
-
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.

“The challenge that I see right now on U.S. farms is a virus getting into hogs,” Osterholm says. Pigs carry receptors similar to the ones found in both humans and birds, making swine a hog-heaven for bird flus that have potential to become a pandemic.

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.
