Mapping how the 100 billion cells in the brain all fit together is the brave new world of neuroscience

Mapping how the 100 billion cells in the brain all fit together is the brave new world of neuroscience

Neuroscience

By Invited Researcher

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 […]

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 […]

Increased density of synapses in autism spectrum disorders

NeurobiologyNeuroscience

By José Ramón Alonso

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 […]

Invasive species are threatening Antarctica’s fragile ecosystems

Invasive species are threatening Antarctica’s fragile ecosystems

BiologyEcology

By Invited Researcher

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 […]

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 Evolution of Murder

The Evolution of Murder

Prepared to kill

By Invited Researcher

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 […]
