A new breakthrough in understanding regeneration in a marine worm | ScienceDaily - 0 views
-
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.
-
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

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,"

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,"

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.

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.
-
start producing defensive compounds that help the plants fight off insect pests.
-
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.

Electrified charcoal sponge soaks up CO2 from the air - 0 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.
-
"You can save a lot of cooling, electricity and energy costs because this is a passive process," Sui said.

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.
-
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.
-
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!

Regeneron ISEF 2023 - Finalist Project Portal - 0 views
-
Choose a category to begin
-
This is a really good way to dive into specific categories and explore the projects that made it to this year's ISEF. What I would do is start with what immediately interests you for now... and pick up some tips. You might get ideas for areas/topics to research. You might see creative methods used in various studies. Pay particular attention to the fact that some utilize equipment only available at a university or corporate lab, but... many also feature creative methods done by students at home or in school labs as well! Once you get inside projects that you get ideas from, feel free to save them in Diigo for later, or share really interesting ones with others you think might benefit from seeing it. One final thing: you might also get some tips for elements of their presentation that appeal to you.

Microwaving an insecticide restores its mosquito-killing power - 1 views
-
Heating an insecticide can give it new life.
-
Microwaving the insecticide deltamethrin rearranges its crystal structure but doesn’t change its chemical composition. The rearrangement renews deltamethrin’s ability to kill mosquitoes that have become resistant to the insecticide, researchers report April 21 in Malaria Journal.
-
The microwave worked just as well, but Kahr cautions that people shouldn’t use the same microwave for heating food and insecticides.
