Examining urban design for past, present and future cities

Increasingly, more people worldwide are living in cities. By the year 2050, it is projected that two-thirds of the global population will reside in urban areas. Living closely together in relatively small spaces offers advantages ...

Molecular cooperation at the threshold of life

Protein-like aggregates known as amyloids can bind to molecules of genetic material. It is possible that these two types of molecules stabilized each other during the development of life—and that this might even have paved ...

Scientists reveal how RNA gets spliced correctly

To carry out all of life's functions, proteins must be produced from instructions carried by genes within DNA and delivered to the cell's protein-making machinery by messenger RNA.

Conducting change: Why copper is key to a renewable future

Copper was discovered in the Neolithic Age about 9,000 years ago. It was the first metal used by humans. And we've continued to value copper ever since. The average family home contains more than 90 kilograms of copper. Every ...

Fossil footprint discoveries and what they tell us

Footprints on a sandy surface don't usually last long: they're washed away by water, wiped out by wind or covered over by new tracks. At certain sites in southern Africa, though, some traces of animals have lasted for many ...

Study identifies characteristics specific to human brains

Researchers led by a team at UT Southwestern Medical Center have identified cellular and molecular features of the brain that set modern humans apart from their closest primate relatives and ancient human ancestors. The findings, ...
