Archaeologists uncovered the body of a wealthy 40-year old man and his young slave in Pompeii, 2,000 years after the eruption of Mount Vesuvius.
Excavations at the suburban villa Civita Giuliana, a suburb outside Pompeii, discovered the bodies covered in a bed of 6.5-foot ash.
Researchers believe that the two men survived the initial eruption from Mount Vesuvius, only to succumb to a massive and more destructive cloud of scorching ash while seeking shelter in a cryptoporticus.
The skeletal remains follow last year’s discovery of another Ancient Roman man crushed by a flying rock during Mount Vesuvius’s eruption in 79 A.D.
Did you know that we shed different types of tears based on our emotions?
Each tear type is composed of unique chemicals — mainly salt, water, and lysozyme — that give them their variable structure.
Emotional tears contain a natural painkiller
According to scientist Claire Phillips, tears of grief contain the neurotransmitter leucine enkephalin which helps relieve the body in times of stress. In such a way, our tear ducts can act as a natural painkiller.
There’s a biological and evolutionary reason we feel better shedding tears after experiencing a traumatic event.
Lake Hillier in the Recherche Archipelago of Western Australia off the coast of Cape Arid National Park is known for its pink color.
The lake’s solid bubble-gum color continues to be debated but scientists indicate that the pink body of water is the result of the intermixing of Halobacteria and a salt-tolerant algae species called Dunaliella Salina.
The Halobacteria is known to produce red pigments which when mixed with salt-tolerant Dunaliella Salina, creates a stunning strawberry milkshake color.
The chemical reactions between the salt and the microorganisms make the lake ten times saltier than the ocean nearby.
Unlike other pink lakes that morph into colors, Lake Hillier retains its pink hue all year round. It’s also safe to swim in.
When viewed from above, the contrast between the pink and dark blue ocean is also striking. You can learn more about the bubblegum lake here.
Did you know that you can blow up soap bubbles and instantly freeze them into ice orbs?
If you’re searching for a fun cold-weather activity, this is worth trying out.
Popular Science explains the science behind bubble freeze, in addition to instructions on how to make one.
There’s some interesting science at play here. Every bubble is made up of three individual layers: a thin layer of water molecules squished between two layers of soap. It might look like the entire surface of the bubble is freezing, but what you’re actually seeing is the innermost layer of water—which freezes at warmer temperatures than soapy water—turning to ice within the film.
As the soapy water turns into ice crystals, the inside of the bubble appears to swirl around to create a beautiful effect of a snowglobe — very photographic!
But the ice bubbles don’t last forever, notes bubble photographer Chris Ratzlaff: “Bubbles are such ephemeral things,” he says. “To be able to literally freeze them in time is such a rare experience.”
MesoSPIMs are open-source light-sheet microscopes for imaging cleared tissue.
The custom-built microscopes enable scientists to look at individual neurons using sheets of light rather than cutting a brain into slices.
The mesoSPIM Initiative paves the way for the future discovery and understanding of the brain’s complex organization. The studies may one day reveal vital information on the neuronal networks that drive mental illnesses and addictions.
