The SDGs and the UN itself have fallen in Gaza. This is a shame!!!!! & It appears that #SDGs can't be applicable equally in the different parts of the world !!!

hello hellsitegenetics. do u know how to stop wanting to eat electrophoresis gel
the craving never stops you just have to get good at eating it when the lab supervisors arent looking
i complain alot when it comes to uni and my course, but not gonna lie, here on my final year i've started to fall in love with it again, the way the fascination started when i was younger and learning new things was exciting.
throughout learning it always felt like i was not built for it, that I just cannot for the life of me focus and dedicate myself on anything. and i was just doubting myself and i should change courses or drop out because I was not meant to do this. and now on my second last semester, things kinda clicked. It may be hard for me to understand and learn, but it's worth it. To see the universe in all of its beauty, its ugliness, its complexity, its charm; it's a struggle but I'll endure it for you.
and I find myself really hoping I get to continue down in the stream of sciences and contribute to something for nature and for humanity as well, or at least deepen my understanding of how this universe works and widen my view of how intricate and special this world we live in actually is, how caring it is, how every single thing is worth something, and nothing from nature is ever truly useless
At the centre of Rosalind Franklin’s tombstone in London’s Willesden Jewish Cemetery is the word “scientist”. This is followed by the inscription, “Her research and discoveries on viruses remain of lasting benefit to mankind.” As one of the twentieth century’s pre-eminent scientists, Franklin’s work has benefited all of humanity. The one-hundredth anniversary of her birth this month is prompting much reflection on her career and research contributions, not least Franklin’s catalytic role in unravelling the structure of DNA.
. . .
But Franklin’s remarkable work on DNA amounts to a fraction of her record and legacy. She was a tireless investigator of nature’s secrets, and worked across biology, chemistry and physics, with a focus on research that mattered to society. She made important advances in the science of coal and carbon, and she became an expert in the study of viruses that cause plant and human diseases. In essence, it is because of Franklin, her collaborators and successors, that today’s researchers are able to use tools such as DNA sequencing and X-ray crystallography to investigate viruses such as SARS-CoV-2.
. . .
Franklin was an inveterate traveller on the global conference circuit and a collaborator with international partners. She won a rare grant (with Klug) from the US National Institutes of Health. She was a global connector in the booming early days of research into virus structures: an expert in pathogenic viruses who had gained an international reputation and cared deeply about putting her research to use. It is a travesty that Franklin is mostly remembered for not receiving full credit for her contributions to the discovery of DNA’s structure. That part of Franklin’s life story must never be forgotten, but she was so much more than the “wronged heroine”, and it’s time to recognize her for the full breadth and depth of her research career.

A quick little note about this bacterium, Nocardia! These are fascinating to me as, although they are a rod-shaped bacteria, they can form beaded, perpendicularly branching filaments that are acid-fast. They can appear morphologically similar to a different bacteria, the anaerobic Actinomyces, however Actinomyces does not exhibit beading like Nocardia does.
This is a Gram-stain of a bacterial embolus within a pulmonary vessel of an Australian marsupial species, and we were lucky enough to know what genus we were dealing with before culture was performed, purely based on the bacteria's morphology!
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 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 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 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.
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.

the slimy green waxcap is an agaric fungus from the family hygrophoraceae. it is found in australia & aotearoa :-) not much else is known about this mushroom.
the big question : can i bite it?? the edibility is unknown.
g./h. graminicolor description :
"the light green cap & stem of this small agaric are covered with a thick, slimy, glutinous coating. a waxy, grey-green, glutinous thread runs along the edges of white waxy gills. the convex cap becomes centrally depressed & ages to brown."

"GREEN BABY !! i couldn't find an exact measurement, but she's *small*. i love this mushroom so so so much<3"
