Human Genome stored on ‘Everlasting’ Memory Crystal

A close-up of a circular transparent disc held between two fingers. The disc contains tiny diagrams and text, displaying information about DNA and human genetic code preservation. The text on the disc reads ’Preserving Human Genetic Code for Eternity: Who Wants to Live Forever?’

University of Southampton scientists have stored the full human genome on a 5D memory crystal—a revolutionary data storage format that can survive for billions of years.

The team hope that the crystal could provide a blueprint to bring humanity back from extinction thousands, millions or even billions of years into the future, should science allow.

The technology could also be used to create an enduring record of the genomes of endangered plant and animal species faced with extinction.

Eternity crystals
The 5D memory crystal was developed by the University of Southampton’s Optoelectronics Research Center (ORC).

Unlike other data storage formats that degrade over time, 5D memory crystals can store up to 360 terabytes of information (in the largest size) without loss for bi...

Weight-maintaining hormone key to brain-signal transmission. A study more closely links obesity to dementia, finding that leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults.

New research is more closely linking obesity to dementia.

Higher levels of leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults, according to a study by The University of Texas Health Science Center at San Antonio (UT Health San Antonio).

“The findings support the known role of leptin variations in late-life d...

Research suggests Neurons Protect and Preserve certain Information through a Dedicated Zone of Stable Synapses

One of the brain’s most celebrated qualities is its adaptability. Changes to neural circuits, whose connections are continually adjusted as we experience and interact with the world, are key to how we learn. But to keep knowledge and memories intact, some parts of the circuitry must be resistant to this constant change.

“Brains have figured out how to navigate this landscape of balancing between stability and flexibility, so that you can have new learning and you can have lifelon...

Gut Microbiome Influences Location of Immune Cells, study finds

Researchers at the Experimental and Clinical Research Center of Max Delbrück Center and Charité — Universitätsmedizin Berlin (ECRC) have found that different anatomical sections of the gastrointestinal tracts of mice carry different compositions of microbial communities. Moreover, the specific makeup of the microbiota can influence the type and abundance of immune cells in any particular region. The study, which was published in Gut Microbes, maps the complex spatial organization of immune cells and microbial communities, providing a tool for studying the interaction between gut microbes and inflammatory diseases.

Previous research has hinted at the existence of “hotspots” along the GI tract where specific immune cells and microbes might interact more intensely.

But no one ha...
