In an important step toward bringing transparent solar cells to home windows, researchers at the University of Michigan have developed a way to manufacture their highly efficient and semitransparent solar cells.

“In principle, we can now scale semitransparent organic solar cells to two meters by two meters, which brings our windows much closer to reality,” said Stephen Forrest, the Peter A. Franken Distinguished University Professor of Electrical Engineering and corresponding author of a study published in Joule.

A team of researchers with affiliations to multiple institutions in the U.S. has found that the metal content of Fermi bubble high-velocity clouds does not match with material in the Milky Way’s galactic center, suggesting that at least some of the material comes from somewhere else. In their paper published in the journal Nature Astronomy, the group describes their analysis of the makeup of the clouds and their conclusions.

Prior research has shown that massive lobes of plasma extend above and below the center of the galactic plane that forms the Milky Way galaxy. Prior research has also suggested that the lobes are globular gas formations which has led to their nickname—Fermi bubbles...

Yale scientists have developed a novel omicron-specific mRNA vaccine that offers superior immune protection against two viral subvariants than standard mRNA vaccines.

The new vaccine, called Omnivax, increased neutralizing antibody response against the BA.1 and BA.2.12.1 omicron subvariants in pre-immunized mice 19-fold and eight-fold, respectively, compared with standard mRNA vaccines. The improved response against the BA.1 subvariant was reported June 6 in the journal Nature Communications. The results of the study involving the BA.2 subvariant were published July 19 in the journal Cell Discovery.

“While standard mRNA vaccines still offer protection against infection from new variants, their effectiveness wanes over time and was compromised due...

Passive day cooling is a promising technology for the sustainable reduction of energy consumption. It avoids the heating up of buildings by solar radiation and dissipates accumulated heat without external energy consumption. Researchers at the University of Bayreuth have now created a test system with which the materials used for passive cooling can be reliably characterised and compared — regardless of weather conditions and environmental conditions...
