Although increased cell proliferation is a hallmark of cancerous tissues, in some cases it may actually protect against tumor growth, according to a new study by Caltech researchers. Using mathematical models, the work suggests ...

Cell-communication molecules called kinases play a key role in the growth and spread of many cancers. But exactly which kinases are active in a particular cancer is not always clear—there are 1.8 million sites on human proteins ...

Companies with strong political connections are more likely to escape scrutiny over greenwashing, according to new research from Durham University Business School. Greenwashing occurs when organizations overstate or misrepresent ...

Archaeologists on Tuesday unveiled the skeletal remains of an adult they believe was buried as an offering near the base of Huaca Pucllana, an ancient adobe pyramid in Peru's capital of Lima.

New research from Purdue University demonstrates how organic aerosol molecules can influence one another's behavior in ways that existing atmospheric models do not fully capture.

Proteins form complex three-dimensional shapes and can join together to create larger structures. Researchers want to use these properties to make artificial materials. However, arranging proteins and synthetic molecules ...

Polymers used for light-based 3D printing are very stable because of their chemical structure, but they are typically hard to recycle. A research team led by Professor Dr. Eva Blasco, a researcher at the Institute for Molecular ...

Scientists have found evidence that a colossal cliff stretching thousands of kilometers across ancient North America may have exposed the heart of the Grand Canyon nearly a billion years before it was carved by the Colorado ...

Optical fibers are already the backbone of global communication systems. Recently, however, physicists have started to explore how their functionality could be boosted further by conveying information via entangled quantum ...

A team of researchers reports that they may have found rock containing some of the earliest forms of microbial life on Earth. Their study, published in the Proceedings of the National Academy of Sciences, describes the biosignatures ...

Biologists, zoologists and psychologists have been trying to trace the origins of human language for centuries. One well-known theory, known as the social brain hypothesis, suggests that increasingly complex social lives ...

So far, most of the minerals found on Mars tell a story of lava poured out by ancient volcanoes, followed by long stretches in which water trickled through and slowly reshaped the rock. However, some rocks scattered across ...
