Nowadays, there is a growing demand for new biosensors capable of detecting specific molecules, contaminants or toxic substances in food, drinking water, air, blood and so forth, with a high degree of sensitivity and specificity. Furthermore, we preferably want these biosensors to be inexpensive, easily reproducible and with a rapid and accurate response. This demand […]

Poor Math Skills Make a Mortgage Default More Likely Unprecedented numbers of American subprime mortgage holders began defaulting on their loans in 2006, precipitating two years later the most severe global recession since The Great Depression. Pundits have offered numerous theories about what started the mortgage mayhem, but firm evidence has remained elusive. According to […]

Human brain has about 85 billion neurons. Each neuron forms thousands of chemical and electrical synapses with other neurons. To record the synaptic activity of each neuron in the brain an intracellular probe with a millivolt scale is required. Glass electrodes are widely used, but they are fragile and they have high impedance. An intracellular […]

Saturn is truly a weird place. Apart from having quite a peculiar thermal history and one of the most interesting satellites in the Solar System, this planet displays arguably the most fascinating meteorological phenomenon ever seen. Suppose for a moment that next spring a storm raises in your hometown. Nothing unusual to care about, probably […]

Violence against women at epidemic proportions Three in ten women worldwide have been punched, shoved, dragged, threatened with weapons, raped, or subjected to other violence from a current or former partner. Close to one in ten have been sexually assaulted by someone other than a partner. Of women who are murdered, more than one in […]

Entanglement is a fundamental tool in quantum computing and several quantum information protocols, such as quantum teleportation, quantum cryptography and quantum key distribution. The basic unit of entanglement is the entangled bit ( ebit ), represented by a maximally entangled state of two qubits (quantum bits). Entanglement can also be implemented in a higher dimensional […]

A complex myriad of factors, many of them related with the global economic crisis, have given rise to a large number of social movements in the latest years. From the Occupy movement to the Arab Spring, or the more recent Turkish protests, most of these phenomena share a notorious fact: having the social networking and […]

The mad hatterpillar These caterpillars are native to Australia and eat eucalyptus trees. Why do they build themselves a hat? No one really seems to know why the caterpillars keep their old heads hanging around. Bug Girl’s Blog When Cleaning fMRI Data is a Nuisance A flaw in data processing could be leading to biases […]

Hope springs eternal: “Pandora’s Promise” and the truth about nuclear energy So why would environmentalists of all people support nuclear power? What changed these people’s minds? Two things, primarily. The Curious Wavefuntion Making and Breaking Compulsive Behaviour When scientists have scanned the brains of people with obsessive-compulsive disorder, they’ve seen more neural activity in areas […]

Have you ever observed how a drop of coffee dries? As water evaporates, its suspended particles are deposited in a ring-like fashion in a phenomenon known as the coffee-ring effect. Obviously, this effect is undesirable in the numerous practical applications that require a uniform coating. However, the way to avoid it has remained unknown. The […]
