Bacterial evolution in ancient sub-seafloor sediments
Micro-organisms persisting deep below the seafloor for millions of years continue to evolve despite living at the energy limit to life......»»
Researchers identify unique phenomenon in Kagome metal
In traditional Japanese basket-weaving, the ancient "Kagome" design seen in many handcrafted creations is characterized by a symmetrical pattern of interlaced triangles with shared corners. In quantum physics, the Kagome name has been borrowed by sci.....»»
New derivative from long pepper shows promise against antibiotic resistance
Antibiotic resistant bacterial pathogens are on the rise, while fewer antibiotics are being developed. Prof. Ariel Kushmaro and his local and international colleagues tackled the need by focusing on the long pepper. Known in traditional medicine for.....»»
How bacteria attach their cloaks of invisibility to immune defenses
Bacteria have different strategies for protecting themselves. Some bacterial pathogens surround themselves with a shell made of many sugar chains that lie close together, also known as capsular polymers. This protects the bacteria from drying out and.....»»
Scientists now know when an ancient lake supported human life in the Namib Sand Sea
Desert regions in northern Africa and the Arabian Peninsula have been well studied by archaeologists as the home of early humans and as routes of migration along "green corridors.".....»»
Has NASA found evidence of ancient life of Mars? An expert examines the latest discovery
NASA has announced the first detection of possible biosignatures in a rock on the surface of Mars. The rock contains the first martian organic matter to be detected by the Perseverance rover, as well as curious discolored spots that could indicate th.....»»
Complex life on Earth began around 1.5 billion years earlier than previously thought, new study claims
Environmental evidence of the very first experiments in the evolution of complex life on Earth, has been uncovered by an international team of scientists......»»
The hidden drivers of evolution: Transposable elements in Rosaceae genomes
Transposable elements are mobile DNA sequences that play a crucial role in plant genome architecture and gene regulation. They drive genome size variation and affect gene expression by altering regulatory networks. Despite their significance, the div.....»»
NASA Mars rover captures rock that could hold fossilized microbes
NASA's Perseverance Mars rover has made what could be its most astonishing discovery to date: possible signs of ancient life on the Red Planet......»»
X-ray microCT unveils ancient pottery techniques
Researchers from Ca' Foscari University of Venice have uncovered insights into ancient pottery forming techniques using X-ray micro-computed tomography (microCT). The study, published in the Journal of Archaeological Science, reveals how advanced 3D.....»»
Invasive, blood-sucking fish "may hold the key to understanding where we came from," say biologists
One of just two vertebrates without a jaw, sea lampreys that are wreaking havoc in Midwestern fisheries are simultaneously helping scientists understand the origins of two important stem cells that drove the evolution of vertebrates......»»
Perseverance rover finds tantalizing hints of possible ancient life on Mars
Perseverance has located some tantalizing indications of possible microbial life on Mars - although it's too early for scientists to be sure......»»
Perseverance rover discovers rock with potential signs of ancient life
A vein-filled rock is catching the eye of the science team of NASA's Perseverance rover. Nicknamed "Cheyava Falls" by the team, the arrowhead-shaped rock contains fascinating traits that may bear on the question of whether Mars was home to microscopi.....»»
Bat evolution study supports gliding-to-flying hypothesis
In new research published in PeerJ, researchers from the University of Washington, University of Texas at Austin and Oregon Institute of Technology, led by undergraduate student Abby Burtner, have advanced our understanding of the evolutionary origin.....»»
Cheesemaking is a complex science—a food chemist explains the process from milk to mozzarella
Cheese is a relatively simple food. It's made with milk, enzymes—these are proteins that can chop up other proteins—bacterial cultures and salt. Lots of complex chemistry goes into the cheesemaking process, which can determine whether the cheese.....»»
"Janus" dual-atom catalyst shows enhanced performance for electrocatalytic oxygen reduction and evolution
A research team led by Prof. Yan Wensheng from the University of Science and Technology of China (USTC) has created the innovative "Janus" dual-atom catalyst (FeCo-N3O3@C) with Fe and Co atoms coordinated synergistically through an N-O bridge, which.....»»
Nude athletes and fights to the death: What really happened at the ancient Olympics
The first recorded victor at the Olympics was Coroebus of Elis. A cook by profession, Coroebus won the event called the "stadion"—a footrace of just under 200 meters, run in a straight line......»»
Scientists assess how large dinosaurs could really get
A new study by Dr. Jordan Mallon of the Canadian Museum of Nature in Ottawa, Canada and Dr. David Hone of Queen Mary University of London, U.K., looks at the maximum possible sizes of dinosaurs. It is published in the journal Ecology and Evolution......»»
Lost lake sheds light on past and future water security
Nestled high in the Eastern Lesotho Highlands, scientists have uncovered fascinating evidence of an ancient mountain lake that flourished thousands of years ago. This discovery, made by Professor Jennifer Fitchett from the University of the Witwaters.....»»
Scientists try to replicate ancient butchering methods to learn how Neanderthals ate birds
It's hard to know what Neanderthals ate: food preparation, especially when it comes to smaller items like birds, can leave few archaeological traces. But understanding their diets is critical to understanding these incredibly adaptable hominins, who.....»»
Boosting plant health: The role of gene exchange with bacteria
A recent study has unveiled how plants and bacteria exchange genes to boost plant health and development. The team discovered 75 genes that were transferred between small, fast-growing plants (Arabidopsis thaliana) and its bacterial companions, influ.....»»
