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......»»
Discovery of ancient rock impression suggests ability to form cornified skin goes back to early evolution of tetrapods
A team of geologists, paleontologists and archaeologists affiliated with several institutions in Poland, Czechia and Germany has found evidence suggesting that the ability to form cornified skin appendages is not unique to terrestrial vertebrates, bu.....»»
Global activity of seafloor biodiversity mapped for the first time
A team of scientists from the U.S. and the U.K. has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world......»»
New molecule found to suppress bacterial antibiotic resistance evolution
Researchers from the University of Oxford have developed a new small molecule that can suppress the evolution of antibiotic resistance in bacteria and make resistant bacteria more susceptible to antibiotics. The paper, "Development of an inhibitor of.....»»
Salty soil sensitizes plants to an unconventional mode of bacterial toxicity
A collaborative study between researchers from the Max Planck Institute for Plant Breeding Research and the Fraunhofer Institute for Molecular Biology and Applied Ecology has shown how a single metabolite can render bacteria toxic to plants under hig.....»»
Bacterial model helps reveal how our bodies prevent population explosions—and cancer
For the size of any population to remain stable over time, its birth and death rates must be balanced. If the birthrate is too high, there could be a population explosion; if it is too low, the population will shrink. This kind of balance exists, for.....»»
The evolution of security metrics for NIST CSF 2.0
CISOs have long been spreadsheet aficionados, soaking up metrics and using them as KPIs for security progress. These metrics have traditionally measured specific systems or single indicators — vulnerabilities detected, percentage of vulnerabilities.....»»
Could Martian atmospheric samples teach us more about the red planet than surface samples?
NASA is actively working to return surface samples from Mars in the next few years, which they hope will help us better understand whether ancient life once existed on the red planet's surface billions of years ago. But what about atmospheric samples.....»»
How to get Ancient Seeds in Stardew Valley
Ancient Seeds are one of the most illusive items in Stardew Valley, but there are ways to find them. Here are the best methods to find these old seeds to grow......»»
Saturday Citations: The cheapness horizon of electric batteries; the battle-worthiness of ancient armor; scared animals
Sometimes, science requires traveling into hazardous environments; sometimes it requires a vast influx of state capital and an army of researchers and technicians. But sometimes, science has to call in the Marines. We reported on that this week, alon.....»»
Earth"s mysterious D" layer: A relic of ancient oceans and planetary collisions
Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid mantle......»»
Historical signs in the landscape: Investigating the practice of pollarding in Western Norway
In the lush landscapes of Western Norway, pollarded trees bridge the past with modern environmental concerns. In a recent study, researchers investigated what motivates farmers to continue this ancient tree pruning practice......»»
On repeat: Biologists observe recurring evolutionary changes, over time, in stick insects
A long-standing debate among evolutionary scientists goes something like this: Does evolution happen in a predictable pattern or does it depend on chance events and contingency? That is, if you could turn back the clock, as celebrated scientist Steph.....»»
Researchers reveal evolutionary origins of appetite by studying simple nervous system of Hydra
Over the course of evolution, living organisms have gradually developed more complex nervous systems in order to coordinate increasingly complex sensory, motor and cognitive functions and to control the associated behavior......»»
A rare find in ancient Timorese mud may rewrite the history of human settlement in Australasia
Humans arrived in Australia at least 65,000 years ago, according to archaeological evidence. These pioneers were part of an early wave of people traveling eastwards from Africa, through Eurasia, and ultimately into Australia and New Guinea......»»
Study sheds light on how antibiotic "Velcro" kills bacteria
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface, similar to how both sides of Velcro form a bond......»»
Study: Grocery shopping habits prove credit worthiness, aiding those without credit history
Recent advances in artificial intelligence and machine learning, coupled with the evolution of large-scale data storage, access and processing technologies, have fueled interest among financial institutions in new data sources for credit scoring......»»
Researchers discover distinct life cycle stages of the ectosymbiotic DPANN archaeon Nanobdella aerobiophila
Archaea are ubiquitous microorganisms whose evolution shaped the biosphere of Earth. Their evolutionary paths are truly fascinating. A great example is an ectosymbiotic lifestyle which is found among DPANN archaea......»»
Ancient Mycenaean armor tested by Marines and pronounced suitable for extended combat
A famous Mycenaean suit of armor was not just ceremonial, but suitable for extended combat, according to a study published May 22 in the open-access journal PLOS ONE by Andreas Flouris of the University of Thessaly, Greece and colleagues......»»
Ancient people hunted now extinct elephants at Tagua Tagua Lake in Chile 12,000 years ago, study finds
Thousands of years ago, early hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephants and take advantage of other local resources, according to a study published May 22 in the open-access journal PLOS ONE by Rafael.....»»
Exploring diversity in cell division: Study investigates the process of evolution that supports diverse life cycles
New research by EMBL scientists shows how different modes of cell division used by animals and fungi might have evolved to support diverse life cycles......»»
