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 […]

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 […]

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 […]

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 […]

Carbon generated by sea-dwelling microbes Microbes living deep in the ocean have been found to produce amorphous carbon, according to findings detailed in Science Advances. Scientists collected and cultured microbes over a number of years, noticing the production of black specks that turned out to be pure carbon. The Scientist Black hole’s plasma jets revealed […]

The San Pedro River winds from rainforests in Guatemala through the Yucatan Peninsula in eastern Mexico. There, this peaceful river widens into a series of slow-flowing lakes. Along a remote 50-mile (80-kilometer) stretch, thousands of red mangroves – trees commonly found along tropical coastlines – line the river’s banks and gentle waterfalls. Unlike mangroves elsewhere […]

  The reason that ibuprofen treats headaches and ice cream tastes sweet is that their chemical components fit perfectly into certain receptors in your body. The better a drug or flavor molecule fits with its matching receptor, the more effective the medicine or tastier the treat. But an interesting quirk of nature is that many […]
