We’re still learning about how trees grow

Coniferous forest in Northern California. Credit: Antoine Capone What will happen to the world’s forests in light of rising global temperatures? Will an increase in carbon dioxide in the atmosphere help trees grow? Or will extreme fluctuations in temperature and precipitation hinder growth? It all depends on whether the tree’s growth is further restricted by … Read more

The digital twin of the fruit fly

A digital model of Drosophila melanogaster called NeuroMechFly. Credit: Pavan Ramdia (EPFL) EPFL scientists have developed a digital model of the fruit fly, Drosophila melanogaster, that realistically simulates the animal’s movements. The twins are a big step toward reverse engineering the neural control of animal behavior, and the development of biologically inspired robots. “We used … Read more

MIT’s Sun-in-a-Box technology uses light as an efficient form of energy

The photovoltaic thermal cell, also called a “heat engine,” measures just one square centimeter, but the research team behind it is looking to expand it. picture: Phyllis Frankl MIT researchers have built a highly efficient thermophotovoltaic cell that when combined with renewable resources, it efficiently converts incoming photons – particles of light – into electricity. … Read more

Researchers find a way to form diodes from superconductors

Credit: Unsplash/CC0 Public Domain A group of researchers from Pisa, Jyväskylä, San Sebastian and MIT have shown how a heterogeneous structure consisting of superconductors and magnets can be used to generate unidirectional current such as that found in semiconductor diodes. However, these new superconducting diodes work very efficiently low temperatures than their semiconductor counterparts, and … Read more

Laser blasts drive the fastest logic gates ever

Simultaneous laser pulses (red and blue) generate a burst of real and virtual charge carriers in graphene that is absorbed by gold metal to produce a net current. “We demonstrated the role of virtual and real charge carriers in laser-induced currents, and this opened the way for the creation of ultrafast logic gates,” says Ignacio … Read more

New research reveals how liars are exposed through distraction

Credit: Pixabay/CC0 Public Domain A new method of lie detection shows that it is easier to identify lie detectors who are given multiple tasks during interviews. It is well documented that lying during interviews consumes more cognitive energy than telling the truth. A new study by the University of Portsmouth found that investigators who used … Read more

A 10-minute meditation can help de-polarize Brexit
