The Truth About Toilet Swirl

This was a pretty fascinating Youtube experiment that not only debunked the famous Simpsons theory about toilets flushing in certain rotational directions depending on what hemisphere you are on, but also proved the coriolis effect.

Sáfrán Anett: Bangka

Az idei tavaszi kiértékelés egyik nagyon várt eseménye volt a MOME Tárgyalkotó Tanszéke és a VPI betonmanufaktúra együttműködésében tartott kurzus, a My Little Concrete eredményeinek prezentációja. A féléves kísérleteés eredményeként született, izgalmas ötletek egyike Sáfrán Anett elsőéves kerámiatervező hallgató projektje.

A BANGKA köztéri beton “tálca” egy olyan kísérletezési folyamat eredménye, amely a elasztikus textíliába öntött újgenerációs beton anyagkísérletek révén jött létre. Az alkalmazott technológia eltér a hagyományos betonöntési módszerektől és azoktól egy sokkal szabad és költséghatékonyabb formálást eredményez. Az előre létrehozott negatív tér kiöntése helyett a beton súlyánál fogva önmaga alakítja ki a formát. A finom felületű, organikus plasztikák a város zöldterületein kapnak helyet, hozzájárulva a piknikezés élményéhez. A moduláris elemek mélyedéseibe poharak, üvegek, dobozok helyezhetőek, akárcsak egy tálcára, amely körül mindenki kap helyet.

Fish Out Of Water

Researchers raised bichirs, which are fish with functional lungs and strong fins. In a pinch, these qualities allow them to walk on land. For eight months, a group of the primitive fish were raised entirely on land so that researchers could compare their development to specimens that grew up in normal, mostly aquatic conditions. Standen and her colleagues thought that the bichir would develop differently if it grew up on land, giving them hints as to how a fish could go from water to earth as it evolved. 

Watch as the bichir (Polypterus senegalus) uses its fins and body to move across a sandy surface. Fins are planted one after the other to lift the head and anterior body, and the tail and body are used to push the fish forward over the planted fin. (Source: E.M. Standen and T.Y. Du)

Sure enough, the fish raised on land walked with a more effective gait

  • They placed their fins closer to their bodies and raised their heads up higher, which made them slip less than the aquatic walkers. 
  • Their skeletons also developed differently, with the bones that support the fins changing shape to support them in higher gravity. 
  • The researchers also saw the fish acquiring more head and neck mobility, which would be important in a transition to life on land.

Dinosaur-Faced Chicken?

With the discovery of feathers on almost every dinosaur species, scepticism around the relationship between modern birds and prehistoric dinosaurs began to dwindle. Since then, more research has been going into learning more about this topic.

Most recently, researchers have put together a study that almost feels like beginnings of a real-life Jurassic Park. By playing with the genome of a chicken embryo, researchers discovered that by simply silencing the gene for beak structure, the shape of the face reverted back to the ancestral snout (see photo). This experiment also serves to illustrate that very small genomic changes can result in significant morphological changes. Unfortunately these little dino-chickens will never live past the embryonic stage due to ethical restrictions. One of the lead authors Bhart-Anjan Bhullar claims that the chickens would have been perfectly healthy, and says that “These weren’t drastic modifications. They are far less weird than many breeds of chicken developed by chicken hobbyists and breeders.” I guess for now, we’ll never know.
