Tracing the origins of organic matter in Martian sediments

Although Mars presents a barren, dusty landscape with no signs of life so far, its geological features such as deltas, lakebeds, and river valleys strongly suggest a past where water once flowed abundantly on its surface. ...

Study may lead to less expensive consumer lasers and LEDs

(Phys.org) -- A recent theoretical study by a University of Waterloo doctoral candidate in nanotechnology engineering suggests that manufacturers may one day make lasers and LEDs out of silicon, with the potential to significantly ...

Study on swirls to optimize contacts between fluids

Physicists who have studied the mixing between two incompatible fluids have found that it is possible to control the undercurrents of one circulating fluid to optimise its exposure to the other. This work, which is about ...

Green photon beams more agile than optical tweezers

Romanian scientists have discovered a novel approach for the optical manipulation of macromolecules and biological cells. Their findings, published in the European Physical Journal B, stem from challenging the idea that visible ...

Earth's inner core may be oxygen-rich

Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it's still unknown whether oxygen is present (and in which form it may exist) in the inner core, which is composed of almost ...
