Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed and demonstrated an innovative set of methods to evaluate long-term aging in real-world battery cells. The methods, described in a recent paper, are based on a phenomenon called nuclear magnetic resonance (NMR), commonly used in medical imaging. This is the first-ever NMRspectroscopy capability that can track in fine detail how the chemistry of commercial pouch battery cells evolves over years of operation.

Argonne develops a novel method that uses nuclear magnetic resonance spectroscopy to characterize the chemical evolution inside battery cells over years of operation.

Researchers have documented a rare supernova, 2023ufx, the most metal-poor stellar explosion observed, located in a dwarf galaxy.

This finding is crucial as it mirrors the early universe’s conditions, aiding astronomers in understanding galaxy formation and evolution.

Researchers have discovered that old elliptical galaxies can form from intense star formation in early galaxy cores.

This finding, derived from data analyzed by the Atacama Large Millimeter/submillimeter Array, shows that these spheroidal galaxies, often considered static and inert, were once dynamic regions of intense star formation during the cosmic noon. This transformative view on galaxy evolution helps clarify the processes behind the formation of the universe’s most massive galaxies.

Summary: Human number cognition may be rooted in the putamen, a deep brain structure traditionally associated with movement rather than abstract thought. Neurosurgery patients demonstrated activity in this area while processing numbers as symbols, words, and concepts, suggesting that numerical understanding emerged early in evolution.

Researchers also observed activity in expected areas like the parietal lobe, highlighting how different brain regions collaborate in number processing. These findings could improve surgical outcomes by protecting areas crucial for number cognition and open pathways to enhancing math learning through targeted interventions.

Death might seem like a pure loss, the disappearance of what makes a living thing distinct from everything else on our planet. But zoom in closer, to the cellular level, and it takes on a different, more nuanced meaning. There is a challenge in simply defining what makes an individual cell alive or dead. Scientists today are working to understand the various ways and reasons that cells disappear, and what these processes mean to biological systems. In this episode, cellular biologist Shai Shaham talks to Steven Strogatz about the different forms of cell death, their roles in evolution and disease, and why the right kinds and patterns of cell death are essential to our development and well-being.

“Kepler-51e has an orbit slightly larger than Venus and is just inside the star’s habitable zone, so a lot more could be going on beyond that distance if we take the time to look,” said Dr. Jessica Libby-Roberts.

How many exoplanets are in the cosmos and what can they tell us about planetary formation and evolution? This is what a recent study published in The Astronomical Journal hopes to address as an international team of more than 50 researchers announced the discovery of Kepler-51e, which is the fourth planet residing in the Kepler-51 system. This discovery holds the potential to expand our knowledge of exoplanets, specifically regarding their formation and evolution, as Kepler-51e challenges previous notions about low-density exoplanets, also called “puff planets” or “Super-Puffs”

“Super puff planets are very unusual in that they have very low mass and low density,” said Dr. Jessica Libby-Roberts, who is a Postdoctoral Scholar in the Department of Astronomy and Astrophysics at Penn State University and second author of the study. “The three previously known planets that orbit the star, Kepler-51, are about the size of Saturn but only a few times the mass of Earth, resulting in a density like cotton candy.”

Has human evolution come to a standstill? Advances in technology and medicine have radically changed the way we live, but could they be changing the course of our genetic future? The surprising truth behind how modern progress may be changing our biology — and what it means for our survival.

Thus, when one looks back in time, say by looking at light from a distant galaxy that has traveled billions of years to reach us, this is akin to “zooming out” on the hologram and making its details fuzzier in the process. This zooming out can continue until all the details of the hologram disappear altogether, which in the model of the universe suggested by Hawking and Hertog, would be the origin of time at the Big Bang.

“The crux of our hypothesis is that when you go back in time, to this earliest, violent, unimaginably complicated phase of the universe, in that phase you find a deeper level of evolution, a level in which even the laws of physics co-evolve with the universe that is taking shape,” Hertog said. “And the consequence is that if you push everything even further backward, into the Big Bang, so to speak, even the laws of physics disappear.”
