Researchers have set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called ‘quantum dots’. The technology has a huge range of potential applications, including the possibility to use it as a flexible, transparent skin to power cars, planes, homes and wearable technology.

The development of next generation solar power technology that has potential to be used as a flexible ‘skin’ over hard surfaces has moved a step closer, thanks to a significant breakthrough at The University of Queensland.

By measuring iron isotopes, researchers have shown that our planet originally formed much faster than previously thought. This finding provides new insights on both planetary formation and the likelihood of water and life elsewhere in the universe.

The precursor of our planet, the proto-Earth, formed within a time span of approximately five million years, shows a new study from the Centre for Star and Planet Formation (StarPlan) at the Globe Institute at the University of Copenhagen.

On an astronomical scale, this is extremely fast, the researchers explain.

If you compare the solar system’s estimated 4...

Antioxidant in Mushrooms may relieve features of ‘Pregnancy Hypertension’

L-( )-Ergothioneine Significantly Improves the Clinical Characteristics of Preeclampsia in the Reduced Uterine Perfusion Pressure Rat Model. Hypertension, 2020; 75 (2): 561 DOI: 10.1161/HYPERTENSIONAHA.119.13929

A new study in rats suggests that the natural antioxidant L-ergothioneine could alleviate the characteristics of pre-eclampsia. Pregnancy hypertension, or Pre-eclampsia, is a complex disorder of pregnancy. Treatment of elevated blood pressure can manage the condition in the mother, but in severe cases delivery is needed, which can present a major problem to the baby if it is born prematurely.

Now, research from the Department of Pharmacology & Therapeutics at University College Cork (UCC), the INFANT Centre at UCC and the University of Liverpool, as well as The Novo Nordis...

‘Flapping Wings’ Powered by the Sun

prototype flexible bio-butterfly-wing, or FBBW

In ancient Greek mythology, Icarus’ wax wings melted when he dared to fly too close to the sun. Now, researchers reporting in ACS Applied Materials & Interfaces have made artificial wings that are actually powered by the sun. The tiny wings, which can flap even faster than those of butterflies, could someday be used in robots or devices for solar energy harvesting, the researchers say.

Light-driven actuators – devices that convert light directly into mechanical work – have attracted attention because they are wireless and easy to control. However, to keep going, they usually require a high-intensity light source that can be turned on and off, or additional hardware...
