Pure hydrodynamic instabilities in active jets of "puller" microalgae
Active fluids can develop spontaneous flow instabilities and complex patterns. However, spatio-temporal control of active particles has remained challenging, despite its relevance in biological and applied contexts. Here, we harnessed phototaxis to steer millions of swimming ``puller" Chlamydomonas reinhardtii algae to create active jets and control both pearling and buckling instabilities through the preferential orientation of the cells. Our experiments, supported by a full analytical model a…

Climate change driving major algae surge in Canada's lakes, study finds
Algal growth is accelerating in lakes across Canada, including those far from human development, and a new study shows that climate change is the primary driver.

You've likely watched a police procedural where the lab states the drowning was suspicious because of algae. The shells of diatoms have long been used in forensic #limnology because they are made of glass, so preserve very well.

Modal analysis and optimization of swimming active filaments
Active flexible filaments form the classical continuum framework for modelling the locomotion of spermatozoa and algae driven by the periodic oscillation of flagella. This framework also applies to the locomotion of various artificial swimmers. Classical studies have quantified the relationship between internal forcing (localised or distributed internal moments or forces) and external output (filament shape and swimming speed). In this paper, we pose locomotion as a mathematical optimisation pr…

Automated Gating for Flow Cytometry Data Using a Kernel-Smoothed EM Algorithm
Phytoplankton are microscopic algae responsible for roughly half of the world's photosynthesis that play a critical role in global carbon cycles and oxygen production, and measuring the abundance of their subtypes across a wide range of spatiotemporal scales is of great relevance to oceanography. High-frequency flow cytometry is a powerful technique in which oceanographers at sea can rapidly record the optical properties of tens of thousands of individual phytoplankton cells every few minutes. …

A #pandemicpond post.
The bog-barrels that I added last summer have done an absolutely incredible job at keeping the water crystal clear and almost completely algae free this summer.
Only the much warmer stream between the ponds has more algae than I really like.
I also added the bigger pump at the same time which likely helped a little but the added flow also raised the level of the top pond just above the liner in some spots. So yesterday when I topped it up, I took away the flat border stones to inspect where it was leaking. It turns out, almost everywhere!
So I added some handfuls of pebble taken from the #poolpond filter since I know there is extra there..: and stuck it under the liner to raise it an inch or two all the way around.
Here is a before and after. The first pic with the purple lilly
pads is last year with the algae that was common in the summer before the big filters. The second pic is a few weeks ago when the pond was full, clear, but overflowing, notice the water overtop the flat stones. The last two pics are today after raising the liner a little under the stones.
And a pic of the happy dual-barrel bogs (which are just small versions of the giant filter I just finished in the backyard). The marsh marigolds have not bloomed in the bog barrels. Not sure if they will this year. It is quite shady for them.
Oh and a lilly is about to bloom!The fish are also very active and happy.

Excitonic Energy Transfer in Red Algal Photosystem I Reveals an Evolutionary Bridge between Cyanobacteria and Plants
Photosystem I converts light into chemical energy with near-unity quantum efficiency,yet its energy-transfer and charge-separation mechanisms remain debated. Evolution has diversified PSI architectures. The unicellular red algae Cyanidioschyzon merolae represents a key evolutionary intermediate,featuring a cyanobacterial-like monomeric core surrounded by three to five LHCR subunits. This hybrid organization provides a unique system to bridge mechanistic models across lineages. We applied two-di…

Disentangling peri-urban river hypoxia
Episodes of low dissolved oxygen concentration--hypoxia--threaten the functioning of and the services provided by aquatic ecosystems, particularly those of urban rivers. Here, we disentangle oxygen-related processes in the highly modified Elbe River flowing through the major German city of Hamburg, where low oxygen levels are frequently observed. We use a process-based biochemical model that describes particulate and dissolved organic matter, micro-algae, their pathogens, and the key reactions …
