An irreversible shift in the chemical makeup of the Arctic Ocean driven by climate change is disrupting the region's food chain, a study suggests. Widespread loss of Arctic sea ice has led to a sharp fall in levels of a key ...

Most major crops, such as wheat and corn, require expensive nitrogen fertilizer to flourish. But what if bacteria could help those plants draw nitrogen from the atmosphere, as peas and beans do?

When doctors and scientists want to see inside a body, magnetic resonance imaging (MRI) is a powerful tool. MRI can noninvasively capture detailed images of the body's muscles, organs, and bones. It can monitor blood flow ...

Researchers have found surprising links that show that Neanderthal ancestry influences our immune system today in ways more nuanced than previously recognized. Their work is published in the journal Genome Biology and Evolution.

NASA's Nancy Grace Roman Space Telescope is poised to make a major leap in the hunt for worlds outside our solar system, known as exoplanets. Scientists expect the mission to reveal around 100,000 worlds—a staggering leap ...

Wild pigs are generally considered among the world's most problematic invasive mammals. But a major new study from Aarhus Universitet shows that the introduced animals may actually have beneficial effects in North American ...

Chemical bonding is one of the central organizing principles of the microscopic world. It determines how atoms combine and thereby governs a wide range of physical and chemical properties of quantum systems across many length ...

While society often assumes that finding a romantic partner is the ultimate key to happiness, tracking relationship changes over time reveals a distinctly different reality. A massive longitudinal study proves that individuals ...

The origin of turtles has always been a bit of a puzzle for scientists who study the evolution of animals. To this day, where they fit in the tree of life remains a highly debated topic.

Astronomers have found some of the strongest evidence yet that stars can swallow their own planets. A new study, published in Monthly Notices of the Royal Astronomical Society, supports the long-held belief that young stars ...

While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have contributed to these shifts.

Using finely tuned nanoscale building blocks, researchers from Brown University and the University of Michigan College of Engineering have stabilized a fleeting structural phase of matter that had been predicted theoretically ...
