⁣When the Soviet Union collapsed in 1990, Cuba's economy went into a tailspin. With imports of oil cut by more than half – and food by 80 percent – people were desperate. This film tells of the hardships and struggles as well as the community and creativity of the Cuban people during this difficult time. Cubans share how they transitioned from a highly mechanized, industrial agricultural system to one using organic methods of farming and local, urban gardens. It is an unusual look into the Cuban culture during this economic crisis, which they call "The Special Period." The film opens with a short history of Peak Oil, a term for the time in our history when world oil production will reach its all-time peak and begin to decline forever. Cuba, the only country that has faced such a crisis – the massive reduction of fossil fuels – is an example of options and hope.

What might seem as waste to Africa’s many herbivores is gold to the Dung Beetle who needs animals dung for its species survival. Not only do these dung beetles gather and roll as much dung as possible but they will even resort to high jacking another’s ball, which it has spent many hours perfecting. But not without a fight.

Driver ants have a gruesome reputation for killing everything in their path, from defenseless worms to a full-size scorpion.

Superswarm (2009)
When animals swarm they create a super-organism of incredible power. They can attack our food supplies, immobilise our transport systems, undermine our cities and even attack our energy supplies. They can stop us in our tracks. Using state-of-the-art photography, Superswarms reveals the collective intelligence behind the animal invasions, and how man fights back.

Virtual Plant Cell: Into Aquaporins highlights the important role that aquaporin proteins play in shuttling water, carbon dioxide and other molecules vital to good plant health, into and out of plant cells.

See https://plantenergy.edu.au/outreach/resources for materials to support classroom use of VPC: Into Aquaporins. This is a curriculum-aligned resource that addresses topics including diffusion across membranes, transcription and translation. This video can also be used with the lesson plan resource: Planting Science: Classifying Systems in Cells (year 7-10), developed by the ARC Centre of Excellence for Translational Photosynthesis: http://photosynthesis.org.au/years7-10/

TRANSCRIPT:
Plants are amazing. They create energy from sunlight and they use this energy to create what we use for our food, fuel and fibre, and this takes us on a journey deep into the inner world of a plant cell.

Plant cells collect sunlight and use it to convert water and carbon dioxide into sugar. This process is called photosynthesis. Photosynthesis happens inside the many green chloroplasts found around a plant cell.

The movement of water, carbon dioxide and other molecules like nitrogen, sugars and salts are vital for good plant health.

But how do water and other solutes get into the cell? Aquaporins are here to help. Aquaporins are tiny protein channels that are created in plant cells. They facilitate diffusion, the movement of important solutes, across cell membranes.
Aquaporins can be found in different membranes of the cell.

Water, carbon dioxide, and more is moved across these membranes, via aquaporin channels, as required.

Let’s see how plant cells create aquaporins when needed.

Proteins like aquaporins are coded for by genes. This is a sequence of information within a cell’s DNA. A message, called RNA, is first created from a gene through a process called transcription.

Messages move out of the nucleus to the ribosome. Here, the RNA message is “read” to create an aquaporin protein. This process of building a protein from an RNA message is called translation.

Aquaporins, like all proteins in a cell, have a unique structure. An aquaporin’s main function is to act as a channel that sits in a membrane. The aquaporin’s structure reflects this role.

Through research we can come to understand how aquaporins work, and how they work best. We can apply this knowledge to produce higher yielding crop plants by maximising their photosynthesis, improving their salt tolerance and enhancing their ability to survive challenging environmental conditions. And more efficient and resilient crops will ensure a secure food future.

This animation by Nucleus shows you the function of plant and animal cells for middle school and high school biology, including organelles like the nucleus, nucleolus, DNA (chromosomes), ribosomes, mitochondria, etc. Also included are ATP molecules, cytoskeleton, cytoplasm, microtubules, proteins, chloroplasts, chlorophyll, cell walls, cell membrane, cilia, flagellae, etc.

Why China keeps Running To Africa by PLO Lumumba

Phoenix, Arizona is home to an unusual kind of resident: the Rosy-faced lovebird. The small, brightly colored parrots are popular cage birds, but here in Phoenix they’ve escaped captivity. Over 25 years, they’ve colonized the desert, with a few useful tricks up their sleeves . . . 🌵 ↠Subscribe: https://www.youtube.com/c/Terr....aMaterOfficial?sub_c

Miles away from their natural African habitat, lovebirds have learned to survive with the aid of cacti, water sprinklers, and a couple of helping hands (and beaks). Take a look at the incredible success story of this plucky little escapee.
