Bronze jewelry sheds light on prehistoric ritual
Excavation at the dried-out lake site of Papowo Biskupie in north-central Poland has revealed more than 550 bronze artifacts, providing the most telling evidence of ritual deposition of metal by the occupants of the region from 1200–450 BC, known a.....»»
Coupling excitons to polaritons for better solar cells and higher intensity LEDs
In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between different processes that lead to loss of energy and thos.....»»
Giant prehistoric flying reptile took off using similar method to bats, study finds
Findings of a study, published in PeerJ, provide new insights into how pterosaurs managed to take flight despite reaching sizes far larger than modern animals. The research sheds new light on the flight initiating jumping ability of these animals, so.....»»

How plants become bushy, or not: New study sheds light on hormone that controls branching
For many plants, more branches means more fruit. But what causes a plant to grow branches? New research from the University of California, Davis shows how plants break down the hormone strigolactone, which suppresses branching, to become more "bushy......»»

First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Retreating Andean rocks signal the world"s glaciers are melting far faster than predicted, report scientists
Rocks recently exposed to the sky after being covered with prehistoric ice show that tropical glaciers have shrunk to their smallest size in more than 11,700 years, revealing the tropics have already warmed past limits last seen earlier in the Holoce.....»»

Penguin wing fossil shows importance of Zealandia in penguin evolution
Three small fossil penguin bones, collected in South Canterbury in 1987, are now shedding new light on how penguin wings have evolved. A new study, published in the Journal of the Royal Society of New Zealand, describes a new species of penguin that.....»»
Polarization and wavelength routers based on diffractive neural network
The concept of deep diffractive neural networks (D2NN) was introduced by Professor Ozcan's research team in 2018. D2NN combines the principles of light diffraction with the functionalities of neural networks. It consists of a series of continuous dif.....»»
