The shape of a fish's caudal tail can tell you a lot about how fast the fish moves! A rounded tail is the slowest and a lunate tail is the fastest! The lunate tail has the most optimal ratio of high thrust and low draw, making it the fastest.

What are Phytoplankton and Why Are They Important?

Breathe deep… and thank phytoplankton.

Why? Like plants on land, these microscopic creatures capture energy from the sun and carbon from the atmosphere to produce oxygen.

Phytoplankton are microscopic organisms that live in watery environments, both salty and fresh. Though tiny, these creatures are the foundation of the aquatic food chain. They not only sustain healthy aquatic ecosystems, they also provide important clues on climate change.

Let’s explore what these creatures are and why they are important for NASA research.

Phytoplankton are diverse

Phytoplankton are an extremely diversified group of organisms, varying from photosynthesizing bacteria, e.g. cyanobacteria, to diatoms, to chalk-coated coccolithophores. Studying this incredibly diverse group is key to understanding the health - and future - of our ocean and life on earth.

Their growth depends on the availability of carbon dioxide, sunlight and nutrients. Like land plants, these creatures require nutrients such as nitrate, phosphate, silicate, and calcium at various levels. When conditions are right, populations can grow explosively, a phenomenon known as a bloom.

Phytoplankton blooms in the South Pacific Ocean with sediment re-suspended from the ocean floor by waves and tides along much of the New Zealand coastline.

Phytoplankton are Foundational

Phytoplankton are the foundation of the aquatic food web, feeding everything from microscopic, animal-like zooplankton to multi-ton whales. Certain species of phytoplankton produce powerful biotoxins that can kill marine life and people who eat contaminated seafood.

Phytoplankton are Part of the Carbon Cycle

Phytoplankton play an important part in the flow of carbon dioxide from the atmosphere into the ocean. Carbon dioxide is consumed during photosynthesis, with carbon being incorporated in the phytoplankton, and as phytoplankton sink a portion of that carbon makes its way into the deep ocean (far away from the atmosphere).

Changes in the growth of phytoplankton may affect atmospheric carbon dioxide concentrations, which impact climate and global surface temperatures. NASA field campaigns like EXPORTS are helping to understand the ocean's impact in terms of storing carbon dioxide.

Phytoplankton are Key to Understanding a Changing Ocean

NASA studies phytoplankton in different ways with satellites, instruments, and ships. Upcoming missions like Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) - set to launch Jan. 2024 - will reveal interactions between the ocean and atmosphere. This includes how they exchange carbon dioxide and how atmospheric aerosols might fuel phytoplankton growth in the ocean.

Information collected by PACE, especially about changes in plankton populations, will be available to researchers all over the world. See how this data will be used.

HORROR WEEK- FOTD #144 : apple bolete! (exsudoporus frostii)

the apple bolete (also frost's bolete) is a mycorrhizal fungus in the family boletaceae >:-) it typically grows near the hardwood trees of the eastern US, southern mexico & costa rica. it was chosen for horror week due to its appearance being reminiscent of muscle tissue !!

the big question : will it kill me?? nope !! however, although they are edible, they are not recommended for consumption as it is quite easy to confuse them with other red boletes. ^^

e. frostii description :

"the shape of the cap of the young fruit body ranges from a half sphere to convex, later becoming broadly convex to flat or shallowly depressed, with a diameter of 5–15 cm (2.0–5.9 in). the edge of the cap is curved inward, although as it ages it can uncurl and turn upward. in moist conditions, the cap surface is sticky as a result of its cuticle, which is made of gelatinized hyphae. if the fruit body has dried out after a rain, the cap is especially shiny, sometimes appearing finely areolate (having a pattern of block-like areas similar to cracked, dried mud). young mushrooms have a whitish bloom on the cap surface.

the colour is bright red initially, but fades with age. the flesh is up to 2.5 cm (1.0 in) thick, & ranges in colour from pallid to pale yellow to lemon yellow. the flesh has a variable staining reaction in response to bruising, so some specimens may turn deep blue almost immediately, while others turn blue weakly & slowly.

the tubes comprising the pore surface (the hymenium) are 9–15 mm deep, yellow to olivaceous yellow (mustard yellow), turning dingy blue when bruised. the pores are small (2 to 3 per mm), circular, & until old age a deep red colour that eventually becomes paler. the pore surface is often beaded with yellowish droplets when young (a distinguishing characteristic), & readily stains blue when bruised. the stipe is 4 to 12 cm (1.6 to 4.7 in) long, & 1 to 2.5 cm (0.4 to 1.0 in) thick at its apex. it is roughly equal in thickness throughout its length, though it may taper somewhat toward the top ; some specimens may appear ventricose (swollen in the middle). the stipe surface is mostly red, or yellowish near the base ; it is reticulate — characterized by ridges arranged in the form of a net-like pattern."

This NPR interview with with Angela Saini about how race science never really left the global scientific consciousness is super interesting! I’m gonna read her book!
