The Hodgkin-Huxley model for the generation of the nerve action potential is one of the most successful mathematical models of a complex biological process that has ever been formulated. Alan Hodgkin and Andrew Huxley described the model in 1952 to explain the ionic mechanisms underlying the initiation and propagation of action potentials in the squid […]

Stronger cyclones could intensify global warming The growing intensity of tropical cyclones in the Pacific may be feeding global warming by speeding up some ocean eddies, suppressing others and carrying more heat via the Kuroshio Current. “The collision of these two giant monsters — tropical cyclones and mesoscale eddies — will probably lead to dramatic […]

When we consider the variety of possible wonder applications of plasmonic nanoparticles we usually forget a key aspect: how these laboratory results can be transformed into something really usable in everyday life. For that to occur some not-that-simple problems must be resolved first. For example, plasmonic nanoparticles exhibit excellent light-harvesting properties in the visible spectral […]

In a new publication led by Dr. Albert Giralt, the researchers discovered the interaction between a transcription factor identified as “Helios” and a protein called “WDFY1” that could help elucidate the link between immunity and schizophrenia . Schizophrenia is an incurable mental illness characterized by relapsing episodes of psychosis. This disorder affects approximately 1% of […]

Miniature robots can carry cancer drug through blood Researchers have created minuscule robots that they say could one day deliver drugs precisely to cancer cells from within patients’ blood streams. The robots, called microrollers, are spherical with a magnetic nanofilm on one half, are coated with the drug doxorubicin on the other half and can […]

High temperatures and strong random interactions need not destroy many-body quantum entanglement

One of the most mysterious features of quantum mechanics is that if two particles (or photons) interact at some point in time then the properties of these particles will remain connected at future times. A consequence of this is that determining the quantum state of one of the particles simultaneously determines the quantum state of […]

Puhahonu shield volcano is Earth’s biggest Scientists say new research shows the Puhahonu volcano, which is about 1,100 kilometers northwest of Honolulu in the Pacific Ocean and contains about 150,000 cubic kilometers of rock, is the world’s largest shield volcano. About a third of it rises above the seafloor, while the rest is buried under […]
