Simulation suggests warm Jupiter exoplanets can be pushed closer to their star by another planet
Old textbook knowledge reconfirmed: Decay rates of radioactive substances are constant
Physikalisch-Technische Bundesanstalt (PTB) researchers refute the assumption that the decay rate of some radioactive nuclides depends on the distance between the Earth and the Sun.
Possible mechanism for the early enrichment of heavy elements in the universe
One of the big mysteries in cosmology is how supermassive black holes formed in the centers of galaxies. Did they form directly from large concentrations of matter and dark matter, or did they form when early ...
Electrically conductive plastics promising for batteries, solar cells
(Phys.org) —An emerging class of electrically conductive plastics called "radical polymers" may bring low-cost, transparent solar cells, flexible and lightweight batteries and ultrathin antistatic coatings ...
Hybrid materials could smash the solar efficiency ceiling
(Phys.org) —A new method for transferring energy from organic to inorganic semiconductors could boost the efficiency of widely used inorganic solar cells.
California solar tower that can kill birds dropped
A solar-energy company has dropped a proposal to build a 75-story tower in California that uses a new kind of technology that can cause some birds to ignite in midair.
Mangroves protecting corals from climate change
Certain types of corals, invertebrates of the sea that have been on Earth for millions of years, appear to have found a way to survive some of their most destructive threats by attaching to and growing under ...
Creating low-cost solar energy
Work by PhD student Alex Barker, under the supervision of Dr Justin Hodgkiss, a senior lecturer in the School of Chemical and Physical Sciences, is helping to improve the efficiency of next generation solar ...
SolarCity loan deal could propel rooftop market
SolarCity will begin offering loans to homeowners for solar systems, a move that industry analysts say could reshape the market for rooftop solar and propel its rapid adoption.
What is the upper limit for massive stars?
Yesterday I mentioned that hypernovae (super-supernovae) are the result of the explosion of a star that's about as massive as a star can be (about 150-200 solar masses). But how exactly do we know that t ...
Study shows most water in lunar soil generated by solar wind, not result of comet or meteorite impacts
Variable glass coatings to stop condensation on windows
Thin-film coatings impart new properties to glass in applications as diverse as window glazing, solar cells and touchscreens. With the Megatron sputtering system, it is now possible for the first time to ...
New mechanism of photoconduction could lead to next-generation excitonic devices
It's a well-known phenomenon in electronics: Shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. But now researchers have discovered ...
