Perovskite-silicon tandem solar cells are considered a key technology for photovoltaics. Because of their design, they use sunlight more efficiently than conventional silicon cells. While the upper perovskite layer absorbs ...

Researchers have discovered how to design and place single-photon sources at the atomic scale inside ultrathin 2D materials, lighting the path for future quantum innovations.

The axolotl, a type of salamander that stays in the tadpole form throughout its life, is a master of regeneration. Axolotls have been observed to regrow several body parts, including limbs, eyes, and even parts of their brains.

Astronomers have employed NASA's Chandra spacecraft to perform X-ray observations of a massive galaxy cluster known as SPT-CL J0217-5014. Results of the observational campaign, published December 4 on the arXiv preprint server, ...

People who treat others with compassion often feel more at ease themselves. This is the key finding of a new study by Majlinda Zhuniq, Dr. Friedericke Winter, and Professor Corina Aguilar-Raab from the University of Mannheim. ...

A research team has developed novel giant acceptors with an oxygenated linker, enabling the creation of highly efficient nonhalogenated-processed organic solar cells (OSCs), with a power conversion efficiency (PCE) of up ...

A laboratory study out of Roswell Park Comprehensive Cancer Center outlines a new way to boost the effectiveness of chimeric antigen receptor (CAR) T-cell therapy in solid-tumor cancers, resulting in their eradication. Led ...

In the wake of a wildfire, a vital micronutrient can become a toxic heavy metal—and could eventually make its way into groundwater.

For decades, nuclear physicists believed that "Islands of Inversion"—regions where the normal rules of nuclear structure suddenly break down—were found mostly in neutron-rich isotopes. In these unusual pockets of the ...

A blood biomarker yet to be used in cardiac arrest care can give a clearer picture of the extent of brain damage after a cardiac arrest. This has been shown in a large international multicenter study led by researchers at ...

St. Hedwig Hospital and Charité–Universitätsmedizin Berlin researchers report that repeated mornings spent under dim indoor light in healthy young adults raised afternoon and evening cortisol and reshaped sleep in ways ...

Parasitic weeds extract water and nutrients from their host plants. But what makes these parasites so successful? A study led by Prof Susann Wicke from the Institute for Evolution and Biodiversity at the University of Münster ...
