Big black holes in little galaxies, rogue black holes and other behemoths could offer clues to cosmic evolution.

A new study unexpectedly reveals that cells thrive on chaos.

Advanced observations by the JWST indicate that early galaxies matured faster and were less chaotic, challenging previous theories of galaxy evolution.

New research has revealed that the Universe’s early galaxies were less turbulent and developed more rapidly than previously believed. This research, led by an international team from Durham University, utilized the James Webb Space Telescope (JWST) to find evidence of bar formation when the Universe was only a few billion years old.

Ever since Darwin introduced his groundbreaking theory of evolution, biologists have been captivated by the complex processes that enable species to evolve.

Can mechanisms responsible for the evolution of a species over a few generations, called microevolution, also explain how species evolve over periods of time extending to thousands or millions of generations, also called macroevolution?

A new paper, just published in Science, shows that the ability of populations to evolve and adapt over a few generations, called evolvability, effectively helps us understand how evolution works on much longer timescales.

In March, the United States reported its first detection of the highly pathogenic H5N1 avian influenza in dairy cattle, with outbreaks spreading to nine states by May. The transmission method among cattle remains unclear. However, a study published in the journal Nature Communications revealed that a similar H5N1 strain, subtype clade 2.3.4.4b, which previously caused an outbreak in farmed mink in 2022, was capable of airborne transmission to a small group of ferrets.

This is the first time that a member of the group of H5N1 clade 2.3.4.4b viruses has been shown to exhibit this ability. According to the Penn State researchers who led the study, the findings suggest these viruses are evolving to infect mammals and with potentially increased risk to humans.

“While there is no evidence that the strain of H5N1 that is presently affecting dairy cattle is capable of airborne transmission, our study suggests that another member of this family of viruses has evolved some degree of airborne transmissibility,” said Troy Sutton, associate professor of veterinary and biomedical sciences, Penn State, and corresponding author on the paper. “This finding underscores the importance of continued surveillance to monitor the evolution of these viruses and their spillover into other mammals, including humans.”

“The planet has a hot core, and that heat source is changing the chemistry of the gases deeper down, but it’s also driving this strong, convective mixing bubbling up from the interior,” said Zafar Rustamkulov.

Gas giant planets within our solar system and exoplanets outside our solar system are known to possess large amounts of gas and small cores, but what if an exoplanet was found to exhibit opposite characteristics? This is what a study published today in Nature hopes to address as a team of international researchers investigated the physical and atmospheric characteristics of WASP-107 b, which is located just over 200 light-years from Earth and has been found to have unique interior characteristics compared to previously discovered exoplanets. These unique findings hold the potential to challenge our understanding of the formation and evolution of gas giant exoplanets, which continue to demonstrate stark contrasts to planets within our solar system.

For the study, the researchers used NASA’s powerful James Webb Space Telescope (JWST) to observe WASP-107 b, discovering that while its radius is slightly less than Jupiter, its mass is only 10 percent of the largest planet in our solar system. Additionally, WASP-107 b possesses methane levels that are one thousand times less than what astronomers anticipated finding, along with having a core whose mass is 12 times larger than the Earth.

Humans are arguably the most peculiar species that has ever existed.

Acknowledging the unique aspects of human evolution underscores our extraordinary place in the grander scheme—a species with one foot in the natural world and the other in a realm of conscious self-awareness and purpose. This dual heritage suggests„.

The discovery could help better understand the origin and evolution of magnetic fields in the cosmos, a mystery that has baffled astronomers for decades.
