The humble neutrino, an elusive subatomic particle that passes effortlessly through normal matter, plays an outsized role among the particles that comprise our universe. To fully explain how our universe came to be, we need to know its mass. But, like so many of us, it avoids being weighed.

Now, an international team of researchers from the United States and Germany leading an ambitious quest called Project 8 reports that their distinctive strategy is a realistic contender to be the first to measure the neutrino mass. Once fully scaled up, Project 8 could help reveal how neutrinos influenced the early evolution of the universe as we know it.

In 2022, the KATRIN research team set an upper bound for how heavy the neutrino could possibly be. That milestone was a tour-de-force accomplishment that has been decades in the making. But these results simply narrow the search window. KATRIN will soon reach and may one day even exceed its targeted detection limits, but the featherweight neutrino might be lighter still, begging the question: “What’s next?”

Following your gut. Losing your appetite. A gutsy move. Though we often consider the gut as merely a digestive tool, these common expressions reflect the central role the gut plays in a much wider range of essential functions.

The entire digestive tract is lined by the enteric nervous system (ENS), a vast network of millions of neurons and glial cells—the two primary cell types also found in the central nervous system. While often called the second brain, the ENS not only generates the same neurotransmitters but actually predates the evolution of the central nervous system in the brain.

The functions of the ENS are crucial to life and extend far beyond digestion, as it regulates immunity, gut secretions, and enables complex, bi-directional communication between the gut and the brain. This is why a happy gut co-exists with a happy brain, and why digestive issues can lead to changes in mood and behavior.

We may have become the most complex living creature in part by accident and replication of error.

AAV development for cell and gene therapy in 2023 is being impacted by manufacturing and regulation challenges, however advancing technologies offer opportunity, according to leaders in the field.

As proven by recent regulatory approvals sweeping the cell and gene therapy industry, particularly within Europe and the US, these pioneering treatments have demonstrated great capacity in helping to resolve hard-to-treat diseases.

Astronomers have observed the outer edge of a disk of matter surrounding a feeding supermassive black hole for the first time.

These observations could help scientists better measure the structures that surround these cosmic monsters, understand how black holes feed on those structures and put together how this feeding influences the evolution of galaxies that house such phenomena.

Mathematicians delight in the beauty of math that so many of us don’t see. But nature is a wonderful realm in which to observe beauty born out of mathematical relationships.

The natural world provides seemingly endless patterns underpinned by numbers – if we can recognize them.

Luckily for us, a motley team of researchers has just uncovered another striking connection between math and nature; between one of the purest forms of mathematics, number theory, and the mechanisms governing the evolution of life on molecular scales, genetics.

An international team of scientists has found a crucial link between the chemistry of Earth’s deep mantle and its early atmosphere. The study uncovers new insights into the evolution of life on our planet and the surge of atmospheric oxygen.

The scientists focused their investigation on magmas formed in ancient subduction zones, areas where portions of Earth’s crust sink back into the mantle.

The experts examined a critical juncture in Earth’s history known as the Great Oxidation Event (GOE), which occurred between 2.1 and 2.4 billion years ago.
