Unlocking the Mysteries of Celestial Flow Features

Posted by in categories: chemistry, space

“Through our simulated impacts, we found that the pure water froze too quickly in a vacuum to effect meaningful change, but salt and water mixtures, or brines, stayed liquid and flowing for a minimum of one hour,” said Dr. Michael J. Poston.


How does extra salty water, also known as briny water, form and evolve on worlds without atmospheres, such as asteroids and moons? This is what a recent study published in The Planetary Science Journal hopes to address as a team of researchers investigated how briny water could still flow for a period of time on the asteroid Vesta after large impacts resulted in the melting of subsurface ice. This study holds the potential to help researchers better understand the geological and chemical processes on planetary bodies without atmospheres and what this could mean for finding life as we know it.

“We wanted to investigate our previously proposed idea that ice underneath the surface of an airless world could be excavated and melted by an impact and then flow along the walls of the impact crater to form distinct surface features,” said Dr. Jennifer Scully, who is a planetary geologist at NASA’s Jet Propulsion Laboratory (JPL) and a co-author on the study.

‘Visual clutter’ alters information flow in the brain

Posted by in categories: mobile phones, neuroscience


Whether we’re staring at our phones, the page of a book, or the person across the table, the objects of our focus never stand in isolation; there are always other objects or people in our field of vision. How that visual “clutter” affects visual processing in the brain, however, is not well understood.

In a new study published Oct. 22 in the journal Neuron, Yale researchers show that this clutter alters how information flows in the brain, as does the precise location of that clutter within the wider field of vision. The findings help clarify the neural basis of perception and offer a deeper understanding of the visual cortex in the brain.

Octopus arm anatomy, molecular makeup revealed in new maps

Posted by in categories: mapping, neuroscience

Octopus arms may literally have a mind of their own. Each limb contains its own version of a spinal cord, called an axial nerve cord, and these cords collectively harbor most of the animal’s neurons.


The datasets provide “a very nice reference” for future functional studies.

Scientists Propose Shooting $200 Trillion Worth of Pulverized Diamonds Into Atmosphere

Posted by in category: futurism

There are ways of cooling the planet, and then there are cool ways of cooling the planet. Spending decades grinding up something approaching a quadrillion dollars worth of diamonds into dust, and then dispersing the powdered gemstones into our atmosphere? That falls into the latter. Contrary to what you might…

Alight, 3Flash to build 120 MW solar park in Finland

Posted by in categories: solar power, sustainability

Sweden’s Alight and Finland’s 3Flash have entered into a joint development agreement to build a 120 MW solar park in Loviisa, a town in southeastern Finland.

Construction is expected to begin early next year, with commissioning currently scheduled for 2027. Once completed, it is expected to generate 155 GWh, equivalent to the annual electricity needs of 31,000 households.

Effect of a giant meteorite impact on Paleoarchean surface environments and life

Posted by in categories: biological, chemistry

Large meteorite impacts must have strongly affected the habitability of the early Earth. Rocks of the Archean Eon record at least 16 major impact events, involving bolides larger than 10 km in diameter. These impacts probably had severe, albeit temporary, consequences for surface environments. However, their effect on early life is not well understood. Here, we analyze the sedimentology, petrography, and carbon isotope geochemistry of sedimentary rocks across the S2 impact event (37 to 58 km carbonaceous chondrite) forming part of the 3.26 Ga Fig Tree Group, South Africa, to evaluate its environmental effects and biological consequences.
