The sea worm Platynereis dumerilii is only a few centimetres long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation.

There are plenty of things about this study that are not so feasible for us at the moment, but... this general area: plant pathology, interactions between native and non-native plants & crops... is a very cool area to explore that would present some feasibility for us.
A new breakthrough in understanding regeneration in a marine worm | ScienceDaily - 0 views

-
Trevor Davids used the California blackworm, Lumbriculus variegatus, to examine the effects of titanium dioxide nanoparticles on regeneration rate. Lumbroculus is a freshwater worm and easy to care for.

-
a research team led by a CNRS scientist1 has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis
-
Even more surprising, the team found that this ability of gut cells to regenerate other tissue varies according to their location: the closer they are to the posterior end of the worm, the greater the variety of cell types they can rebuild

There are elements of this study that connect to what Trevor Davids & Grant Reed were doing last year... but with a different model organism.

Simple new process stores CO2 in concrete without compromising strength - 0 views
-
By using a carbonated -- rather than a still -- water-based solution during the concrete manufacturing process, a Northwestern University-led team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction material.
-
Not only could the new process help sequester CO2 from the ever-warming atmosphere, it also results in concrete with uncompromised strength and durability.

"The cement and concrete industries significantly contribute to human-caused CO2 emissions,"

Know anyone who works with concrete that might let you experiment? I had a student back in the day who did this. They incorporated plastic polymer beads into standard concrete molds for strength testing.
Common plastics could passively cool and heat buildings with the seasons | ScienceDaily - 0 views

Researchers at Princeton and UCLA have developed a passive mechanism to cool buildings in the summer and warm them in the winter.
-
coatings engineered from common materials can achieve energy savings and thermal comfort that goes beyond what traditional building envelopes can achieve

"With the increase in global temperatures, maintaining habitable buildings has become a global challenge,"

Don't know if you're following changes in climate, but... this might be an area for some engineering. What are the other problems involved with this field of study? Interesting to anyone?
New fabric cools people in sweltering cities - 0 views
-
researchers have designed a new wearable fabric to help people beat the heat in urban settings. The material, reported in the journal Science, could find use in clothing, cooling facades for buildings and cars, and for food storage and transport.
-
Existing cooling fabrics reflect sunlight and also wick away sweat to cool a person via evaporation. More recently, researchers have designed cooling fabrics that rely on the principle of radiative cooling: the natural phenomenon in which objects radiate heat through the atmosphere straight into outer space.
-
But radiative cooling fabrics made so far are designed to work when laid horizontally as opposed to vertically, as they would be when worn.

Materials science is certainly a nifty bit of engineering. This is the second time I've seen this study mentioned. Look interesting enough to dig into various materials and how they might be combined to serve a key purpose?
Ignoring Noise Pollution Harms Public Health - 1 views

I think this shows tons of promise for feasibility- especially since we have an international airport nearby, and measuring sound is straightforward. Acquiring the data acquisition probes to do this is certainly feasible. A lot of room for creativity here. If this is interesting, also dig into ARC-GIS as a tool to geographically map out the sound data generated.

Are plants intelligent? It depends on the definition | ScienceDaily - 1 views
-
When leaf beetle larvae eat goldenrod leaves, the plant emits a chemical that informs the insect that the plant is damaged and is a poor source of food. These airborne chemicals, called volatile organic compounds (VOCs), are also picked up by neighboring goldenrod plants, prompting them to produce their own defenses against the beetle larvae. In this way, goldenrod move herbivores on to neighbors, and distribute damage.
-
Are these VOCs (volatile organic compounds) detectable by us? If not detectable, they can we identify them... and then produce or purchase those chemicals to test their effects on plant responses?
-
-
start producing defensive compounds that help the plants fight off insect pests.
-
It seems to me that I remember hydrogen peroxide being one of these signaling chemicals (at least from one part of a plant to another).
-
-
When no neighbors are present, the plants don't resort to accelerated growth when eaten and the chemical responses to herbivores are markedly different, though they still tolerate quite high amounts of herbivory.

"When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby."
Electrified charcoal sponge soaks up CO2 from the air - 1 views
-
With a little bit of electric charge, the sponge-like charcoal material used in household water filters can also capture carbon dioxide from air, researchers report in the journal Nature. The advance could provide a low-cost, efficient route for removing the greenhouse gas from the atmosphere.
-
For the material, the researchers turned to an activated charcoal sponge, a porous substance with a large surface area. The material is commonly found in household purifiers to capture chemicals and toxins from water. Activated charcoal cannot efficiently capture carbon dioxide from air normally. But chemist Alexander Forse and his colleagues proposed that inserting charged, reactive particles into activated charcoal could turn it into a direct air capture sorbent.
-
The researchers charged the activated charcoal cloth in a battery-like setup. They used the cloth like one electrode in a battery, placing it in a solvent solution with an opposite electrode. When they passed electricity through the device, charged hydroxide ions accumulate in the tiny pores of the charcoal cloth.

New fabric makes urban heat islands more bearable | ScienceDaily - 0 views
-
This year has already seen massive heatwaves around the globe, with cities in Mexico, India, Pakistan and Oman hitting temperatures near or past 50 degrees Celsius (122 degrees Fahrenheit).
-
In tests under the Arizona sun, the material kept 2.3 degrees Celsius (4.1 degrees Fahrenheit) cooler than the broadband emitter fabric used for outdoor endurance sports and 8.9 degrees Celsius (16 degrees Fahrenheit) cooler than the commercialized silk commonly used for shirts, dresses and other summer clothing.

Mysterious Underwater Acoustic World of British Ponds Revealed in New Study | Current S... - 1 views
-
The previously hidden and diverse underwater acoustic world in British ponds has been revealed by a team of researchers at the University of Bristol.
-
So... my immediate thought is: How cool would it be to do this here? One thing we DO have: PONDS. See if this *sounds* interesting. Get it? ;)
-
-
Acoustic monitoring has been shown to effectively survey birds and monkeys in rainforests, and marine mammals in the oceans. However, freshwater environments have remained largely unexplored despite their diverse soundscapes.
-
BOOM. Again, "relatively unexplored" is super exciting verbiage to me. Acoustics. Hydrophones. Is this feasible? Is the equipment affordable? If not, could we borrow one? Dig into it. What are the possibilities?
-
-
analysis of the audio files revealed clear daily acoustic activity cycles in each pond
-
Aside from the exploratory surveys you would do just to see "what's out there" and assess what we CAN learn from listening to a pond, you could make it experimental by comparing ponds you've assessed the health of by other means. In other words, do acoustic comparisons between two ponds correlate with what you find by doing a macroinvertebrate sampling? I really LIKE the possibilities in this one!
