New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
Tuberculosis under the sea: A marine sponge microbe provides insights into the bacterium"s evolution
The surprising discovery of a bacterium in a marine sponge from the Great Barrier Reef with striking similarity to Mycobacterium tuberculosis, the pathogen responsible for tuberculosis (TB), could unlock and inform future TB research and treatment st.....»»
Spectroscopy study reveals electrons in cocatalyst periphery drive photocatalytic hydrogen evolution
Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT–IR spectroscopy, researchers led by Toshiki Sugimoto succeeded in observing and identifying the reactive electron species for photocatalytic hydroge.....»»
Larger ant colonies drive the evolution of worker castes: Division of labor is key to life"s complexity, says study
Just like human societies, ant societies have a division of labor. Within a colony, some individuals feed the young while others are soldiers who protect the colony from intruders. New research across 794 ant species, published in Nature Ecology & Ev.....»»
Land-sea "tag-team" devastated ocean life millions of years ago, reveal scientists
Scientists have revealed how a "tag-team" between the oceans and continents millions of years ago devastated marine life—and altered the course of evolution on Earth......»»
From rhino horn snuff to pangolin livestock feed: A half-century of patents reveals the wildlife trade"s evolution
The bright blue blood of the horseshoe crab is used around the world to detect bacterial contamination in vaccines. Synonymous with luxury, sturgeon caviar has been patented as an antidote to impotency in China. Rhino horn is used in traditional Asia.....»»
Scientists use evolution to bioengineer new pathways to sustainable energy and pharmaceuticals
Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucos.....»»
Vernicia montana"s genome unearths new breeding horizons
A study has unveiled the genetic blueprint of Vernicia montana, a plant renowned for its high-value tung oil and ornamental beauty. The research decodes its chromosome-level genome, providing unparalleled insights into its evolution and setting the s.....»»
Survival tactics: AI-driven insights into chromatin changes for winter dormancy in axillary buds
Evolution has enabled plants to survive under adverse conditions. The winter bud of a plant is a crucial structure that establishes adaptability. Depending on environmental and intrinsic conditions, buds can transition between growth and dormancy. Th.....»»
The disappearing mountains and hungry volcano: Researching the evolution of the Teton Range
Once upon a time, the Teton Range, a 40-mile-long mountain range in the northern Rocky Mountains, may have extended much longer than it does now......»»
Ancient microbes linked to evolution of human immune proteins
When you become infected with a virus, some of the first weapons your body deploys to fight it are those passed down to us from our microbial ancestors billions of years ago. According to new research from The University of Texas at Austin, two key e.....»»
What the unique shape of the human heart tells us about our evolution
Mammals, from the mighty blue whale to the tiny shrew, inhabit nearly every corner of our planet. Their remarkable adaptability to different environments has long fascinated scientists, with each species developing unique traits to survive and thrive.....»»
The evolution of the Trappist-1 planetary system
Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around them, such as asteroids and moons......»»
