A brain is folded to increase the surface area for neurons. If you present a koala with leaves plucked from a branch, laid on a flat surface, the koala will not recognise it as food. They are too thick to adapt their feeding behaviour to cope with change. In a room full of potential food, they can literally starve to death.

This is not the token of an animal that is winning at life. Speaking of stupidity and food, one of the likely reasons for their primitive brains is the fact that additionally to being poisonous, eucalyptus leaves (the only thing they eat) have almost no nutritional value.

They can't afford the extra energy to think, they sleep more than 80% of their fucking lives. When they are awake all they do is eat, shit and occasionally scream like fucking satan. Because eucalyptus leaves hold such little nutritional value, koalas have to ferment the leaves in their guts for days on end.

Unlike their brains, they have the largest hind gut to body ratio of any mammal. Many herbivorous mammals have adaptations to cope with harsh plant life taking its toll on their teeth, rodents for instance have teeth that never stop growing, some animals only have teeth on their lower jaw, grinding plant matter on bony plates in the tops of their mouths, others have enlarged molars that distribute the wear and break down plant matter more efficiently... Koalas are no exception, when their teeth erode down to nothing, they resolve the situation by starving to death, because they're fucking terrible animals. Being mammals, koalas raise their joeys on milk (admittedly, one of the lowest milk yields to body ratio... There's a trend here). When the young joey needs to transition from rich, nourishing substances like milk, to eucalyptus (a plant that seems to be making it abundantly clear that it doesn't want to be eaten), it finds it does not have the necessary gut flora to digest the leaves.

To remedy this, the young joey begins nuzzling its mother's anus until she leaks a little diarrhoea (actually fecal pap, slightly less digested), which he then proceeds to slurp on. This partially digested plant matter gives him just what he needs to start developing his digestive system. Of course, he may not even have needed to bother nuzzling his mother. She may have been suffering from incontinence. Why? Because koalas are riddled with chlamydia. In some areas the infection rate is 80% or higher. This statistic isn't helped by the fact that one of the few other activities koalas will spend their precious energy on is rape.

Despite being seasonal breeders, males seem to either not know or care, and will simply overpower a female regardless of whether she is ovulating. If she fights back, he may drag them both out of the tree, which brings us full circle back to the brain: Koalas have a higher than average quantity of cerebrospinal fluid in their brains. This is to protect their brains from injury... should they fall from a tree. An animal so thick it has its own little built in special ed helmet. I fucking hate them.

Tldr; Koalas are stupid, leaky, STI riddled sex offenders. But, hey. They look cute. If you ignore the terrifying snake eyes and terrifying feet.

And after a quarter-century of hard work, they have abundant evidence to prove it. Give people a sugar pill, they have shown, and those patients — especially if they have one of the chronic, stress-related conditions that register the strongest placebo effects and if the treatment is delivered by someone in whom they have confidence — will improve. Tell someone a normal milkshake is a diet beverage, and his gut will respond as if the drink were low fat. Take athletes to the top of the Alps, put them on exercise machines and hook them to an oxygen tank, and they will perform better than when they are breathing room air — even if room air is all that’s in the tank. Wake a patient from surgery and tell him you’ve done an arthroscopic repair, and his knee gets better even if all you did was knock him out and put a couple of incisions in his skin. Give a drug a fancy name, and it works better than if you don’t.

Aided by functional magnetic resonance imaging (f.M.R.I.) and other precise surveillance techniques, Kaptchuk and his colleagues have begun to elucidate an ensemble of biochemical processes that may finally account for how placebos work and why they are more effective for some people, and some disorders, than others. The molecules, in other words, appear to be emerging. And their emergence may reveal fundamental flaws in the way we understand the body’s healing mechanisms, and the way we evaluate whether more standard medical interventions in those processes work, or don’t. Long a useful foil for medical science, the placebo effect might soon represent a more fundamental challenge to it.

Spektrum der Wissenschaft hat geschrieben:Placebo wirkt auch ohne Täuschung

Wichtigste Voraussetzung für den Placebo-Effekt ist die Ahnungslosigkeit des Patienten: Er darf nicht wissen, dass er nur ein Scheinmedikament einnimmt – so glaubte man jedenfalls bisher. Nun zeigten Wissenschaftler jedoch, dass Placebos sogar dann wirken, wenn sie als solche gekennzeichnet sind.

Ted Kaptchuk von der Harvard Medical School in Boston und seine Kollegen führten dazu eine dreiwöchige Studie an 80 Patienten durch, die am Reizdarmsyndrom litten. Dabei teilten sie die Probanden in zwei Gruppen auf: Die eine Hälfte bekam keine Behandlung, die andere Hälfte erhielt Placebo-Kapseln, die sie zweimal am Tag einnehmen sollten. Die Mediziner beschrieben diese den Patienten gegenüber ehrlich als "Zuckerpillen" und machten ihnen deutlich, dass diese keine wirksamen Substanzen enthielten. Zusätzlich waren die Packungen mit dem Wort "Placebo" beschriftet. Kaptchuk betont: "Wir erzählten den Patienten, dass sie nicht einmal an den Placeboeffekt glauben müssten. Sie sollten nur die Pillen nehmen."

Nach drei Wochen haben sich bei 59 Prozent der Patienten, die das Placebo nahmen, die Symptome deutlich verbessert. Bei den Beteiligten, die keine Pillen genommen hatten, waren dies hingegen deutlich weniger, nämlich nur 35 Prozent. Die Forscher betonen jedoch, dass es sich um eine sehr kleine Studie handelt und die Ergebnisse noch in umfangreicheren Untersuchungen bestätigt werden müssten. Offen bleibt bei seiner Studie außerdem, ob auf herkömmliche Weise verabreichte Placebos nicht vielleicht noch besser gewirkt hätten. Dennoch: "Die Erkenntnisse deuten darauf hin, dass nicht allein positives Denken, sondern auch die schlichte Durchführung eines medizinischen Rituals einen signifikanten Nutzen haben könnte", meint Kaptchuk.

In our survey, we asked thousands of people around the world about the places they have found their lost remote and some of the answers were surprising:

• 49% found the remote in the couch
• 8% found it in the bathroom
• 8% in a dresser drawer
• 4% in the fridge/freezer
• 2% have found the remote outside or all the way out in the car
