These findings dispute the former theory, suggesting the organic materials come from within the dwarf planet or are “endogenous.”

“The significance of this discovery lies in the fact that, if these are endogenous materials, it would confirm the existence of internal energy sources that could support biological processes,” team leader and Instituto de Astrofísica de Andalucía researcher Juan Luis Rizos said in a statement.

To investigate the organic compounds found on Ceres, the team used a new approach that examined the dwarf planet’s surface and the distribution of organic matter at the highest possible resolution.

World-leading scientists have called for a halt on research to create “mirror life” microbes amid concerns that the synthetic organisms would present an “unprecedented risk” to life on Earth.

The international group of Nobel laureates and other experts warn that mirror bacteria, constructed from mirror images of molecules found in nature, could become established in the environment and slip past the immune defences of natural organisms, putting humans, animals and plants at risk of lethal infections.

NASA’s Synthetic Biology Project is collaborating with the GrabCAD community to create innovative 3D-printable bioreactor designs. These bioreactors aim to reduce the mass and volume of supplies needed for extended space missions by enabling in-situ production of essential nutrients through reusable or recyclable solutions.

The project focuses on enhancing BioNutrient Production Packs, which use bio-engineered microorganisms to generate critical nutrients like beta carotene. Crews activate these microorganisms by adding water and growth media to dormant cultures. The existing bioreactors include early polycarbonate Gen-0 models and lightweight Gen-1 soft packs. Both designs allow gas exchange to prevent over-pressurization while ensuring safe nutrient production.

NASA seeks to address key challenges for long-duration missions, including designing bioreactors that are either reusable or recyclable and can be manufactured aboard spacecraft. The bioreactor must safely handle liquid cultures, support gas exchange, and be compatible with additive manufacturing technologies. Reusability designs must consider sterilization challenges, while recyclable designs should use materials that can be reprocessed into new bioreactors.

New research reveals that centromeres, which are responsible for proper cell division, can rapidly reorganize over short time scales. Biologists at the University of Rochester are calling a discovery they made in a mysterious region of the chromosome known as the centromere a potential game-changer in the field of chromosome biology.

“We’re really excited about this work,” says Amanda Larracuente, the Nathaniel and Helen Wisch Professor of Biology, whose lab oversaw the research that led to the findings, which appear in PLOS Biology.

The discovery involves an intricate and seemingly carefully choreographed genetic tug-of-war between elements in the centromere, which is responsible for proper cell division. Instead of storing genes, centromeres anchor proteins that move chromosomes around the cell as it splits. If a centromere fails to function, cells may divide with too few or too many chromosomes.

Cyanobacteria use an AM radio-like principle to coordinate cell division with circadian rhythms, encoding information through pulse amplitude modulation.

Cyanobacteria, an ancient group of photosynthetic bacteria, have been discovered to regulate their genes using the same physics principle used in AM radio transmission.

New research published in Current Biology has found that cyanobacteria use variations in the amplitude (strength) of a pulse to convey information in single cells. The finding sheds light on how biological rhythms work together to regulate cellular processes.

Early biology may not have been an ocean exclusive.

When the brain is observed through imaging, there is a lot of “noise,” which is spontaneous electrical activity that comes from a resting brain. This appears to be different from brain activity that comes from sensory inputs, but just how similar—or different—the noise is from the signal has been a matter of debate.

New research led by a team at the University of Tokyo further untangles the relationship between internally generated noise and stimulus-related patterns in the brain, and finds that the patterns of spontaneous activity and stimulus-evoked response are similar in lower visual areas of the cerebral cortex, but gradually become independent, or “orthogonal,” as one moves from lower to higher visual areas.

The findings not only enhance our understanding of the mechanism that enables the brain to distinguish between signal and noise, but could also provide clues for developing noise-resistant artificial intelligence incorporating a mechanism similar to that found in the biological brain. The study is published in the journal Nature Communications.
