For many animals, siblings are a key component of their social environment during early life. Previous research has shown that the early social environment is important, but it has not yet been clear whether the number of ...

At Rice University, a research lab's signature keepsake has helped perfect a method for growing patterned diamond surfaces that could help decrease operating temperatures in electronics by 23 degrees Celsius. The paper is ...

For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA's Chandra X-ray Observatory. The bubble—called an "astrosphere"—completely surrounds ...

A team of scientists led by the German Center for Integrative Biodiversity Research (iDiv), the Helmholtz Center for Environmental Research (UFZ), and Leipzig University has developed a new method to track Earth's greenness—a ...

When the federal government brings its toughest environmental enforcement actions against polluters, they tend to be in communities of greater wealth, not the most polluted places. That's the takeaway from a new paper co-authored ...

Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature. Packed with proteins and fats, it serves as a dense storage reservoir for a developing embryo. Yet the ...

UNSW engineers have tackled a longstanding problem at the heart of global agriculture: how to make urea for fertilizer without the intensity of emissions associated with fossil-fuel-powered factories. The solution is outlined ...

Sometimes, transporting electrons from one cell to another is a team effort. In electroactive bacteria, that team is a group of proteins that shepherds electrons forward, passing them along like a relay baton, so they can ...

Drugs made of mRNA have the potential to transform medicine—if only they could get into cells in one piece. Now, University of Connecticut researchers have shown that packaging mRNA like a virus could smuggle it into cells ...

Digital technologies are widely viewed as drivers of efficiency, growth, and innovation. However, their contribution to climate change is significantly greater than previously understood. A new study published in the journal ...

The deep, murky pigment known as Prussian blue put the "blue" in traditional blueprints, colored Hokusai's "Great Wave off Kanagawa" and today is used for industrial purposes, from laundry to battery components to poison ...

Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
