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.....»»
Coinfecting viruses obstruct each other"s cell invasion
The process by which phages—viruses that infect and replicate within bacteria—enter cells has been studied for over 50 years. In a new study, researchers from the University of Illinois Urbana-Champaign and Texas A&M University have used cutting-.....»»
New compound found to be effective against "flesh-eating" bacteria
Researchers at Washington University School of Medicine in St. Louis have developed a novel compound that effectively clears bacterial infections in mice, including those that can result in rare but potentially fatal "flesh-eating" illnesses. The com.....»»
Researchers demonstrate mechanism that may have stabilized the first RNA molecules
The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team at ORIGINS, a Munich-based Cluster of Excellence, has demonstrated a mechanism that could have.....»»
3D terrestrial laser scanner assists in reconstructing glacier"s mass balance sequence
Complex topography of glacier surfaces under accelerating global warming presents unprecedented challenges to traditional methods of glaciological observation due to intense fragmentation and differential melting......»»
Penguin wing fossil shows importance of Zealandia in penguin evolution
Three small fossil penguin bones, collected in South Canterbury in 1987, are now shedding new light on how penguin wings have evolved. A new study, published in the Journal of the Royal Society of New Zealand, describes a new species of penguin that.....»»
Engineered microbes found to repel mosquitoes
Genetically-engineered human skin bacteria can make mice less attractive to mosquitoes for 11 days. Mosquitoes transmit a host of deadly diseases, including malaria, West Nile, dengue, yellow fever, and Zika. Female mosquitoes on the hunt for a blood.....»»
Elusive predicted water structure created in the laboratory
Clathrate hydrates are complex water structures that contain foreign guest molecules inside a host water-molecule shell. A predicted clathrate hydrate phase structure has been stably synthesized in the lab and may play an important role in future mat.....»»
Green synthesis of copper oxide nanoparticles from mangifera indica: A solution for agricultural disease management
A research team has successfully synthesized green copper oxide nanoparticles (CuO.NPs) from Mangifera indica (M. indica) leaf extract. The CuO.NPs showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on p.....»»
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.....»»
Genomewide prediction: A promising approach for improving russet formation in apple breeding programs
A research team has demonstrated that genomewide prediction is a promising approach for targeting russet formation in apple breeding programs. This method effectively predicts the russet trait, which is a complex quantitative trait controlled by many.....»»
Scientists convert bacteria into efficient cellulose producers
Bacteria produce materials that are of interest to humans, such as cellulose, silk and minerals. The advantage of producing bacteria in this way is that it is sustainable, takes place at room temperature and in water. A disadvantage is that the proce.....»»
New research offers insight on modeling belief dynamics
Researchers who study belief dynamics often use analogies to understand and model the complex cognitive–social systems that underlie why we believe the things we do and how those beliefs can change over time. Ideas can be transmitted like a virus,.....»»

Great news for the endangered tiger: A 250% increase in tiger numbers recorded in Thailand
There's phenomenal news for the Endangered tiger: There's been a 250% increase in tiger numbers in Thailand's Western Forest Complex (WEFCOM) over a 15-year period from 2007 to 2023......»»
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......»»
Unlocking carbon"s potential: CRISPR boosts lignocellulose absorption
Lignocellulosic biomass, such as paper mulberry, holds promise for sustainable material production due to its cost-effectiveness and renewability. However, optimizing lignin composition remains challenging due to its complex structure and varied comp.....»»
Researchers develop 3D printed model for targeted antibiotic therapy against follicular infections
Hair follicle infections are often difficult to treat because bacteria settle in the gap between hair and skin, where it is difficult for active substances to reach them......»»
New and improved drug-delivery molecules for skeletal muscle
Researchers from Tokyo Metropolitan University have created a new drug-delivery molecule, a zwitterionic polymer complex that can help get plasmid DNA inside cells when injected into skeletal muscle, a crucial step in the expression of therapeutic RN.....»»
