Jewel Wasp Turning a Cockroach into a Zombie … Caught in the Act of Injecting Neuro-Toxins Directly Into the Brain … The neurosurgically altered victim recovers from its paralysis but now lacks the will to flee or fight. The wasp pulls on an antenna and leads the roach, like a dog on a leash, into a burrow. There she glues an egg to the underside of the roach. She leaves the burrow and seals it shut. In the darkness, the roach stands motionless as the wasp larva hatches from its egg and chews a hole into its side. The wasp feeds through the hole for a while, and then slithers inside. Later, it pops out as a full-grown adult.

C8 (Per- and polyfluoroalkyl substances – PFAS) Made up of a chain of carbon atoms, surrounded by fluorine atoms. PFAS is a nearly unbreakable compound.
PFAS exposure has been linked to an increased risk of testicular and kidney cancer, thyroid and immune system issues, and developmental problems in fetuses and newborns. PFAS chemicals can potentially cause male infertility and smaller penis size. The U.S. Environmental Protection Agency’s lifetime healthy advisory number is 70 parts per trillion.

Ichthyosaur. About 26 meters (85 feet) long. (Artist: Nobumichi Tamura)
Ichthyosaurs appeared during the start of the Triassic, some 250 million years ago. Though they initially lived along coasts, they eventually moved to deeper water. At their height, they filled many niches, from ambush predator to suction feeder and were among the most successful animals in the oceans. But about 90 million years ago, almost 25 million years before the dinosaurs disappeared, ichthyosaurs died out.

Naked lizard proves hair, scales and feathers descend from single reptilian ancestor …suggests all of these animals, including humans, descended from a single reptilian ancestor approximately 320 million years ago. … This picture shows (from bottom to top) bearded dragons that are: normal, heterozygous mutant (it received only one copy, either from its mother or from its father, of the mutated EDA gene) and homozygous mutant (it received two copies of the EDA mutation: one from its father and one from its mother). The homozygous mutant lacks all scales, while the heterozygous mutant has scales that are reduced in size. Photo by Michel C. Milinkovitch

The Original Ghostbuster “Apparently the combination of the fan and the geometry of the room had produced a standing sound wave at a frequency of just under 19 Hz. This frequency, part of a region of frequencies dubbed infrasound, is just out of the range of normal human hearing, but is very close to the average resonant frequency of a human eyeball. This caused the lab workers’ eyes to vibrate very slightly, prompting the curious optical illusions.”

Crystal Misorientation Toughens Human Tooth Enamel
The enamel that covers the exposed surface of human teeth is the hardest tissue in the human body. Incredibly, this protective layer enables our teeth to last a lifetime. In contrast, mouse teeth grow continuously as they get worn down. In sharks and parrotfish, a new row of teeth is always ready to move forward and take over for failing ones. In crocodiles, when a tooth falls out, another one erupts. None of this happens with permanent teeth in humans, despite the fact that our teeth must withstand chewing pressures on the order of 1 GPa—comparable to pressures found 30 km underground—applied hundreds of times each day for a lifetime. How does enamel achieve such spectacular performance, despite the tremendous pressures to which it is exposed?

Fluid Identity “When a caterpillar enters the chrysalis stage, it is not merely sprouting wings to become a moth or butterfly. Enzymes inside the chrysalis completely dissolve the entire caterpillar—brain, organs, and all—into a nutrient-rich slurry of protein. Only a few cells remain alive. Once the caterpillar has self-digested, an alternate section of DNA inside the few remaining living cells is expressed, and the cells use the nutrient soup to multiply and develop the new organism. In essence the animal is a chimera; the caterpillar lives and dies, and an entirely new organism emerges from its remains.”

- “Forest trees are interconnected through extensive mycorrhizal fungal networks that can interlink different tree species. Carbon can move from one tree to another through these hyphal networks.”
- “Sixty-seven Douglas fir trees of various ages were found to be intricately connected below ground by ectomychorrhiza from the Rhizopogon genus. Rhizopogon, which means ‘root beard’ in Greek, is commonly found living in a symbiotic relationship with pine and fir trees, and thus is thought to play an important ecological role in coniferous forests. Areas occupied and trees connected by Rhizopogon vesiculosus are shaded blue, or shown with blue lines, while Rhizopogon vinicolor colonies and connections between trees are coloured pink, or shown by pink lines. The most highly connected tree was linked to 47 other trees through eight colonies of R. vesiculosus and three of R. vinicolor.”

Coccolithophores, from whence comes Chalk
Tiny algae called coccolithophores, such as this Discosphaera tubifera, play a major role in the global carbon cycle.
Lith size: 3->8µm; Coccosphere size: 12->20µm; Liths per sphere: 35->70
µ = micrometer, or 1/1,000,000 of one meter, or 1/1,000 of one millimeter
After death of the algae, the chalky shell sinks to the ocean floor and becomes an abundant component of sea-floor carbonates. Over millions of years these shells have accumulated to form thick sediment layers, with the chalk cliff of the German island of Rügen being a prominent example. Due to the incorporation of trace elements from the waters surrounding the cells into the chalk structures, which are produced inside the cells, the chemical composition of these sediments can give information about the climate and environment of the past. https://www.mpikg.mpg.de/5677694/orakel-aus-dem-ozean
Blooms of a tiny algae called coccolithophores near the Falkland Islands are visible from space as bright turquoise swirls. New research shows that coccolithophores are mysteriously scarce in one of the most fertile and productive regions of the Atlantic Ocean.
They bind million tons of carbon dioxide yearly, removing the greenhouse gas from the atmosphere. Each chalky coccolith that ends up on the sea-floor removes carbon from the atmosphere-ocean cycle for thousands of years. The acidification of the oceans due to raising atmospheric carbon dioxide concentrations poses a threat to biological chalk formation and the consequences of this on our climate are poorly understood. https://www.mpikg.mpg.de/5677694/orakel-aus-dem-ozean

Welcome to the Plastisphere Plastics are energy-rich substances, which is why many of them burn so readily. Any organism that could unlock and use that energy would do well in the Anthropocene. Terrestrial bacteria and fungi which can manage this trick are already familiar to experts in the field. Dr Mincer and Dr Amaral-Zettler found evidence of them on their marine plastic, too.
They noticed many of their pieces of debris sported surface pits around two microns across. Such pits are about the size of a bacterial cell. Closer examination showed that some of these pits did, indeed, contain bacteria, and that in several cases these bacteria were dividing and thus, by the perverse arithmetic of biological terminology, multiplying. Though the two researchers have not yet proved the bugs in the pits are actually eating the plastic, that hypothesis seems a good bet. And if they are, it suggests plastic pollution in the ocean may not hang around as long as has often been feared.
Less encouragingly, Dr Mincer and Dr Amaral-Zettler also found cholera-like bacteria in their tiny floating ecosystems. Both fish and seabirds act as vectors for cholera (the former bring it into human settlements when caught by fishermen, the latter when resting ashore or nesting), so anywhere that such creatures might pick up cholera bugs is something worth keeping an eye on.

A bedbug magnified 50 times. (Volker Steger/Photo Researchers)
Bed Bugs: A New Debugger … The new trap could be used both to assess whether a hotel room or apartment is infested and also to kill the insects without dousing everything in insecticide—which is, in any case, an increasingly futile exercise, as many have now evolved resistance.
Body Hair: The Not-So-Naked Ape … When the bug was on a hairy patch it was detected, on average, every four seconds. When it was on a shaved patch, more than ten seconds elapsed between detections. Moreover, the bugs seemed to find it harder to locate a good spot to bite when they were surrounded by hair.
