Scientists say the brief African Humid Period began and ended suddenly, about 5,000 years ago. MIT news D. McGee, P.B. deMenocal, G. Winckler, J.-B. Stuut […]

How good are neuron models?

Neuroscience

By Jorge Mejías

For several decades now, physicists, mathematicians, neurobiologists and other specialists have been joining efforts to build realistic mathematical models of neurons. A typical model consists on one or several differential equations that are able to predict the evolution of the membrane potential of a neuron for a given input. When introduced in a computer, these […]

Scientists use 3D printer to create networks of artificial cells Researchers have developed networks of water droplets that can act like biological tissue cells. The researchers created the networks using a three-dimensional printer. The networks can support up to 35,000 droplets and have the potential to be a scaffold for growing synthetic tissues or a […]

Flowers are the reproductive organs of angiosperms (flowering plants) and flowering is therefore the phenomenon by which the undifferentiated cells from the meristems (similar to animal stem cells) differentiate into a floral meristem that will then produce the different components of the flower (sepals, petals, stamens and carpels). This transition from a plant vegetative to […]
