AskScience AMA Series: Hey Reddit! We are scientists working with forest and tree height data, including land cover and carbon. Many of us use a combination of satellite and ground measurements in our research with NASA and beyond. AUA about trees and how they can help us regulate climate change. Posted: 06 May 2021 04:00 AM PDT Trees are diverse, and tree height can tell us a lot about Earth's ecosystems. Satellites and ground-based measurements are used to track tree location, growth, monitor how well an ecosystem supports trees, and estimate how much carbon is stored by trees. GLOBE encourages the citizen scientist community to use the GLOBE Observer app to take tree height measurements with their smartphones. These observations are added to a freely available, global inventory of tree height. Tree science experts are standing by. Ask us anything! Nancy Glenn, Remote Sensing Researcher, Forest Ecosystems, Boise State University (NASA ICESat-2 Early Adopter) Erika Podest, Physical Scientist, Carbon Cycle and Ecosystems Group, NASA Jet Propulsion Laboratory Lola Fatoyinbo, Research Physical Scientist, Forest Ecology and Ecosystems, NASA Goddard Space Flight Center Paul Montesano, Physical Researcher, Remote Sensing of Boreal Forest Structure, NASA Goddard Space Flight Center Peder Nelson, Researcher and Instructor, NASA GLOBE Observer Land Cover Science Lead, Oregon State University Brian Campbell, NASA Senior Earth Science Specialist, NASA GLOBE Observer Trees Science Lead, NASA Wallops Flight Facility We'll be online from 2-3 PM ET (6-7 PM UTC) to answer your questions. See you soon! You can download the GLOBE Observer app and start taking tree height measurements today. You can also take part in our current Community Trees Challenge now through May 15. Always follow guidelines from your local officials, and only participate in GLOBE activities or use the GLOBE Observer app if it is safe to do so.

How many cells would you need to start off 'growing' viral vectors for vaccine production? Posted: 06 May 2021 03:47 AM PDT Just thinking about the global need for vaccines and the challenges industry is facing in getting production of the vaccines set up. How expensive are they? submitted by /u/dancingn1nja [link] [comments]

What are the substances in Covid-19 rapid ag test? Posted: 06 May 2021 03:30 AM PDT We recently started taking the COVID 19 ag rapid tests (you know the ones that you put 1-2 cm into your nose and swirl around before putting them in a buffer solution and dripping them onto a test kit) at school. A couple of friends and I started wondering what the substance inside the test that produces the red control line is and what the substance producing the red line in the antigen field is. Can anyone help us out? submitted by /u/H4ns3mand [link] [comments]

Do all objects really fall at the same rate, barring air resistance? Posted: 05 May 2021 03:24 PM PDT Falling questions: I've always been told by instructors that everything falls with the same rate of acceleration. I've always imagined that there would be variations. Assuming that the drag coefficients or shapes of two objects are the same, could mass not have an effect in a non-vacuum environment. I completely understand that in a vacuum, all objects subjected to the same gravity, and only to that force, accelerate at the same rate. However, in an atmosphere doesn't density matter? I don't know if "buoyancy" is the right word to use when speaking of air, but don't objects have different levels of it depending on how their densities compare to that of the air? For example, a balloon filled with air exhaled from the lungs eventually sinks as it is slightly denser than air but it takes a while. Would this effect not apply to all objects. I understand that it would probably be negligible but I am just wondering if it is there. I've always been told that the mass of an object falling is irrelevant to the rate of acceleration. I have seen how it works out mathematically and have always accepted this but have never completed understood why conceptually. All masses have a gravitational acceleration. When I fall to the Earth, it falls to me. Why does it not abide my body's gravitational acceleration. Instructors have always told me that no matter how massive an object is, it will always accelerate to the Earth at 9.81 m/s^2. Why. If something falls to Jupiter it accelerates at 24.79 m/s^2. If Earth falls to Jupiter, and Jupiter to Earth, which constant of acceleration is used. If my instructors were correct, Jupiter, no matter how massive will fall to the Earth at 9.81 m/s^2. How does this work? Thanks Edit: Realized I phrased the title incorrectly. I meant barring variations in air resistance between the objects. submitted by /u/MrNincompoopy [link] [comments]

Statistically, when can we expect another active igneous province on earth? Posted: 05 May 2021 12:02 PM PDT Also, for what percentage of time, over the course of earth's history, have there been active igneous provinces? submitted by /u/transley [link] [comments]
