A new analysis of 105-year-old data on the effectiveness of 'dazzle' camouflage on battleships in World War I has found that while dazzle had some effect, the 'horizon effect' had far more influence ...

We're all familiar with Pavlovian conditioning, in which a reward-anticipatory behavior follows a reward-predicting stimulus. Perhaps you experience it yourself when passing a cafe or restaurant and ...

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a ...

Researchers show that precisely layering nano-thin materials creates excitons -- essentially, artificial atoms -- that can act as quantum information bits, or qubits.

Researchers have demonstrated a technique for successfully encapsulating bacteria that can then be stored and applied to plants to improve plant growth and protect against pests and pathogens. The ...

Early-life adversity affects more than half of the world's children and is a significant risk factor for cognitive and mental health problems later in life. In an extensive and up-to-the-minute review ...

A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, according to a new study.

Engineers developed a method to grow artificial muscle tissue that twitches and flexes in multiple, coordinated directions. These tissues could be useful for building 'biohybrid' robots powered by ...

The only iguanas outside the Americas, Fiji iguanas are an enigma. A new genetic analysis shows that they are most closely related to the North American desert iguana, having separated about 34 ...

A research team has uncovered new insights into the molecular mechanisms of ADAR1, a protein that regulates ribonucleic acid (RNA) induced immune responses. Their findings could open new pathways for ...

It has long been thought that only nerve and heart cells use electric impulses to communicate, while epithelial cells -- which compose the linings of our skin, organs and body cavities -- are mute, ...

Cells are in constant competition with each other and so eliminate diseased or unwanted cells. Cell competition is therefore a central principle for maintaining the health of tissues and organs.
