The brain plays an essential role in how people navigate the world by generating both thought and behavior. Despite being one of the most vital organs of life, it takes up only 2% of human body volume. How can something so small perform such complex tasks? Luckily, modern tools like brain mapping have allowed neuroscientists […]
DISCLAIMER: in no way is this an article to justify not getting vaccinated or not wearing a mask in closed spaces! At this point, I think most of us can agree that a diet rich in vegetables/fruits is good for your health. But what wasn’t entirely clear was the relationship between nutrition and COVID-19 risk […]
Feathery bridge between galaxy’s arms A bridge of gas resembling a feather has been observed between a pair of the Milky Way’s spiral arms. The Gangotri wave, observed using APEX telescope data, reaches from the Norma arm to the 3-kiloparsec arm near the galaxy’s center and features a sine-like wave. Science News How to locate […]
The advent of on-surface chemistry under vacuum has vastly increased our capabilities to synthesize carbon nanomaterials with atomic precision. Among the types of target structures that have been synthesized by these means, one-dimensional graphene nanoribbons (GNRs) have probably attracted the most attention, and for a good reason: the enormous tunability of GNRs’ electronic properties is […]
At a synapse, the plasma membrane of the neuron transmitting the information (the presynaptic neuron) is in close proximity to the membrane of the target cell (postsynaptic) and the two are separated by a space known as the synaptic cleft. Both the presynaptic and postsynaptic sites contain extensive assemblies of molecular machinery that link the […]
We tend to think Antarctica is isolated and far away – biologically speaking, this is true. But the continent is busier than you probably imagine, with many national programs and tourist operators crisscrossing the globe to get there. And each vessel, each cargo item, and each person could be harbouring non-native species, hitchhiking their way […]
Massive simulation suite offers views of universe Astronomers have created AbacusSummit, a simulation suite of the universe that contains roughly 60 trillion particles across more than 160 simulations that model the ways dark matter and visible matter interact in a box-shaped environment. Universe Today Infection-fighting cells found in lungfish cocoons The cocoons that encase African […]
Cromophores are generally groups of atoms having delocalized electrons. Covalent assemblies of conjugated organic chromophores provide the opportunity to engineer new excited states with novel properties. A team of researchers has now used a novel cage architecture for creating them. The properties of organic electronic materials being determined by the interactions between their conjugated subunits […]
The transformation of a bundle of more or less deep insights on a few voting procedures, as we saw in a preceding entry, into something like a general logico-mathematical theory about the aggregation of individual preferences into a collective choice was the work of a single man, Kenneth Arrow, in his 1951 book Social choice […]
The American evolutionary psychologist David Buss contends in his 2005 book The Murderer Next Door: Why the Mind Is Designed to Kill that the evolutionary process humans acquired psychological adaptations to facilitate homicide. Natural selection, it is hypothesized, winnowed and perfected psychological mechanisms that solved certain problems by facilitating homicidal behavior. Of course, to solve […]
