Why eukaryotes, not bacteria, evolved complex multicellularity
Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around 1–1.5 billion years la.....»»
Rhythmic gene expression in plants is crucial for symbiosis with nutrient-providing bacteria, study finds
Legumes thrive in low-nitrogen environments by partnering with rhizobia, soil bacteria that convert atmospheric nitrogen into ammonium, a usable form for the plants. These beneficial bacteria are housed in root nodules formed on legume roots......»»
Global chaos erupts as Windows security update goes bad
The vast majority of corporate IT worldwide is struggling on Friday morning, with things as mundane as point-of-purchase, and as complex as flight management not working because of a bad Windows security patch by security firm CrowdStrike.An unknown.....»»
GenAI network acceleration requires prior WAN optimization
As GenAI models used for natural language processing, image generation, and other complex tasks often rely on large datasets that must be transmitted between distributed locations, including data centers and edge devices, WAN optimization is essentia.....»»
New AI approach accelerates targeted materials discovery and sets the stage for self-driving experiments
Scientists have developed an AI-based method that helps gather data more efficiently in the search for new materials, allowing researchers to navigate complex design challenges with greater precision and speed......»»
Of ants and trees: "Evolutionary déjà vu" in the tropical rainforest
Ants are famous for their regimented and complex social behaviors. In the tropics, they are also famous for forming mutualisms with plants. Certain species of trees have conspicuous hollow swellings that house ants, often feeding the ants with specia.....»»
Nature"s gender reveal: Key gene controls female flowers in Cucurbita pepo
Sex determination in cucurbits such as squash is influenced by a complex interplay of environmental, hormonal, and genetic factors, with ethylene being the primary hormone promoting female flower development......»»
Ginseng"s full genome sequenced
Ginseng's role in traditional medicine is underscored by its complex genetic structure due to its allotetraploid nature. A recent study delves into this complexity, revealing key evolutionary insights into its subgenomes that govern saponin biosynthe.....»»
Study shows small animals use "stolen" genes from bacteria to protect against infection
Certain small, freshwater animals protect themselves from infections using antibiotic recipes "stolen" from bacteria, according to new research by a team from the University of Oxford, the University of Stirling and the Marine Biological Laboratory (.....»»
Crown-of-thorns starfish larvae feast on toxic cyanobacteria, study finds
Researchers have uncovered an under-the-sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as "sea sawdust.".....»»
Microbial structures in Antarctic lake could reveal more about how life evolved
In the depths of remote Antarctic lakes, communities of microorganisms are thriving where few life forms can survive. Scientists are studying structures formed by these communities to understand more about microscopic life in these extreme environmen.....»»
Scientists add the human element to long-term flood predictions
To better predict long-term flooding risk, scientists at the Department of Energy's Oak Ridge National Laboratory developed a 3D modeling framework that captures the complex dynamics of water as it flows across the landscape. The framework seeks to p.....»»
Modular design: New insights into protein factories in human mitochondria
The "power plants" of living cells, the mitochondria, probably evolved through endosymbiosis: A bacterium migrated into a primordial cell and eventually developed into an organelle that provides the cell with energy, among other things. Mitochondria.....»»
Study identifies rhizobacteria to combat Striga and boost sorghum yields in Ethiopia
A research team has identified potential Striga-suppressing rhizobacteria associated with sorghum, which have been shown to significantly reduce Striga seed germination rates. This study highlights the value of soil-borne bacteria as bioherbicides to.....»»
Ancient microbes offer clues to how complex life evolved
A new study published in Science Advances reveals a surprising twist in the evolutionary history of complex life. Researchers at Queen Mary University of London have discovered that a single-celled organism, a close relative of animals, harbors the r.....»»
Harmonic Protect helps security teams secure sensitive data
Harmonic Security launched Harmonic Protect which empowers security teams with the tools to protect sensitive data without the headaches of labeling and complex rules. CISOs using Harmonic have coined it “zero-touch data protection” for its uniqu.....»»
Paris 2024 Olympics to face complex cyber threats
While previous Olympic games have faced cybersecurity threats, the Games of the XXXIII Olympiad, also known as Paris 2024, will see the largest number of threats, the most complex threat landscape, the largest ecosystem of threat actors, and the high.....»»
Researchers directly simulate the fusion of oxygen and carbon nuclei
The fusion of two nuclei is a complex process influenced by many factors. These factors include not only the relative energy and angular momentum of the two nuclei, but also how their structures evolve as they collide. The outcome of the collisions i.....»»
Interdisciplinary approach provides new insights into molecular mechanisms of cholera infection
Cholera infections caused by Vibrio cholerae bacteria can be life-threatening and the trigger is the cholera toxin produced by the bacteria. It binds to the surface of intestinal cells—more precisely, to certain "sugar lipids" (GM1 gangliosides, GM.....»»
Study unveils complexity of zoonotic transmission chains
Researchers from the Complexity Science Hub and the University of Veterinary Medicine Vienna have dissected the complex interactions involved in zoonoses, which annually affect over two billion people worldwide. They introduce the concept of a "zoono.....»»
Scientists demonstrate chemical reservoir computation using the formose reaction
Researchers from the Institute for Molecules and Materials at Radboud University, Netherlands, have demonstrated that a complex self-organizing chemical reaction network can perform various computational tasks, such as nonlinear classification and co.....»»
