How Smells Trigger Memories By SciShow

SciShow explains how smells can bring back early memories – even memories that your brain didn’t know you had.

Mammals both produce milk and have hair. Ergo, a coconut is a mammal.

High Current/Amps through metal

Any metal that can conduct low voltage / high amperage electricity acts as a resistor between two electrode wires (as in the case above), which are made out of copper, which has a better conductivity than iron/steel which heats up due to the extreme electrical resistance. 

Copper (Cu):

Resistivity: ρ(Ω·m) at 20ºC = 1.68×10−8

Conductivity: σ (S/m) at 20ºC = 5.96×107 

Temp. Coefficient:  0.003862 (K−1)

Iron (Fe): (although what you see in the gif is steel, iron comes pretty close)

Resistivity: ρ(Ω m) at 20ºC = 1.00×10−7

Conductivity: σ (S/m) at 20ºC = 1.00×107

Temp. Coefficient: 0.005 (K−1)

The Oldest Ancestor of Modern Birds Has Been Found in China

Ever since the birdlike dinosaur Archaeopteryx was first discovered in 1861, paleontologists have tried to decipher the evolutionary origins of modern birds—the only surviving descendants of the dinosaurs.

Now, paleontologists based out of the Chinese Academy of Sciences (CAS) have reached a new milestone in this quest. The CAS team has discovered the oldest fossils from the Ornithuromorpha group of dinosaurs, the common ancestor of all modern bird species.

The two specimens date back 130 million years to the Early Cretaceous period, when pterosaurs still dominated the skies. They belong to a new species named Archaeornithura meemannae, a feathered wading bird that lived in what is now northeastern China. The CAS team, led by paleontologist Min Wang, published a detailed analysis of the new specimens today in Nature Communications.

Giant Centipede - Scolopendra subspinipes

Scolopendra subspinipes (Scolopendromorpha - Scolopendridae) is a really huge and fast growing centipede that can exceed 20 cm in length. They are voracious, strictly carnivores, and also poisonous, feeding mostly on small insects, spiders, earthworms, and other arthropods.

Scolopendra subspinipes is cosmopolitan in tropical and subtropical regions of the world, where these animals serve an ecologically important role as soil and leaf litter predators.

The sting of this centipede reportedly causes intense pain, burning, swelling, and erythema.

Moon Night Mushroom (Tsukiyotake) - Omphalotus japonicus

A spectacular photo of the bioluminescent fruiting bodies of the mushrooms scientifically named Omphalotus japonicus (Marasmiaceae), glowing in the darkness.

The glowing fungi grow on wood and their light is visible at night. Luminous higher fungi emit greenish light with a maximum emission in the range of 520–530 nm. A luminous taxon emits light in only a certain period of its life cycle; before and after that period, it generally does not glow.

Omphalotus japonicus is known from Japan and other sites in East Asia, where it is regarded as a poisonous mushroom. 

Synonymous: Lampteromyces japonicus
