Our brains use internet search engine strategies to remember words and memories of past experiences.

In a recent study of epilepsy patients and healthy volunteers, National Institutes of Health researchers found that our brains may withdraw some common words, like “pig,” “tank,” and “door,” much more often than others, including “cat,” “street,” and “stair.” By combining memory tests, brain wave recordings, and surveys of billions of words published in books, news articles and internet encyclopedia pages, the researchers not only showed how our brains may recall words but also memories of our past experiences.

“We found that some wo...

Scientists have made a pivotal breakthrough in the important, emerging field of spintronics—which could lead to a new high speed energy efficient data technology.

An international team of researchers, including the University of Exeter, has made a revolutionary discovery that has the potential to provide high speed, low power-usage for some of the world’s most well-used electronic devices.

While today’s information technology relies on electronics that consumes a huge amount of energy, the electrons within electric currents can also transfer a form of angular momentum called spin.

‘Spin-based electronics or ‘spintronics’, that exploits spin current, has the potential to be not just significantly faster, but also more energy efficient.

Scientists have recently discovered ...

The fastest-growing black hole in the universe is 34 billion times the mass of our sun and feasts on a meal the equivalent of our sun each day, according to a new study.

This massive, hungry black hole was first identified and studied by researchers in May 2018. Previously, they believed it consumed the mass equivalent to our sun every two days. Now, they have a better understanding of this monster black hole and its gluttonous behavior.

The black hole is known as J2157 and exists more than 12 billion light-years back in the distant universe. Astronomers are trying to understand how such massive black holes could evolve during the early days of the universe. The researchers continue to search for more massive black holes like this one to understand how they have grown.

Standard semiconductor technology is reaching its limit in miniaturization, but the demand for smaller electrical devices with higher performance continues to grow. The research group introduced the widest graphene nanoribbon.

With literally the thickness of one carbon atom and electrical properties that can surpass those of standard semiconductor technologies, graphene nanoribbons promise a new generation of miniaturized electronic devices. The theory, however, remains far ahead of reality, with current graphene nanoribbons falling short of their potential...
