Switching Up: Marine Bacteria Shift Between Lifestyles to Get the Best Resources

Researchers have found that marine bacteria exploit resource patches efficiently by switching between attached and planktonic lifestyles, and ...

Genome of Alexander Fleming's Original Penicillin-Producing Mold Sequenced

Researchers have sequenced the genome of Alexander Fleming's penicillin mould for the first time and compared it to later ...

Mystery of Giant Proton Pump Solved

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a ...

Customizable Synthetic Antibiotic Outmaneuvers Resistant Bacteria

Antibiotic resistance is one of the world's most urgent public health threats. In the United States alone, tens of thousands of deaths result each year from drug-resistant strains of common bacteria ...

Color-Coded Biosensor Illuminates in Real Time How Viruses Attack Hosts

All viruses can only do damage by replicating inside the cells of another organism, their host. Researchers have now shown an important mechanism in this host-attacking process, at the ...

Mechanism That Causes Cell Nuclei to Grow

Researchers discover a mechanism that causes cell nuclei to ...

Chemists Make Cellular Forces Visible at the Molecular Scale

Scientists have developed a new technique using tools made of luminescent DNA, lit up like fireflies, to visualize the mechanical forces of cells at the molecular ...

Researchers Find New Way to Protect Plants from Fungal Infection

Widespread fungal disease in plants can be controlled with a commercially available chemical that has been primarily used in medicine until now. In a comprehensive experiment scientists have ...

New Drug Candidate Found for Hand, Foot and Mouth Disease

Researchers have identified a potential drug candidate against enterovirus 71, a common cause of hand, foot and mouth disease in infants and young children. The compound of interest is a small ...

E. Coli Bacteria Offer Path to Improving Photosynthesis

Scientists have engineered a key plant enzyme and introduced it in Escherichia coli bacteria in order to create an optimal experimental environment for studying how to speed up photosynthesis, a holy ...

Technique Permits Convenient, Precise Optical Imaging of Individual Proteins

In a new study, researchers describe a method for examining proteins in keen detail. To do this, his group makes clever use of a phenomenon known as surface plasmon resonance (SPR), incorporating it ...

Your Cells Look Young for Their Age, Compared to a Chimp's

Many humans live to see their 80s, some even reach 100. But chimpanzees rarely make it past 50, despite sharing 99% of our genetic code. While modern medicine has added years to human lifespans, a ...

Biologists Create New Genetic Systems to Neutralize Gene Drives

Addressing concerns about gene drive releases in the wild, scientists have developed two new genetic systems that halt or eliminate gene drives after release. Created in fruit flies, the e-CHACRs and ...

New High-Speed Test Shows How Antibiotics Combine to Kill Bacteria

Researchers have developed a new method to determine - rapidly, easily and cheaply - how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for ...

Invasive Shrimp-Sucking Parasite Continues Northward Pacific Expansion

Researchers have identified an invasive blood-sucking parasite on mud shrimp in the waters of British Columbia's Calvert Island. The discovery represents the northern-most record of the parasite ...

'Cellular Compass' Guides Stem Cell Division in Plants

Biologists observing the formation of leaves noticed the nuclei moved in bewildering ways. Further investigation uncovered proteins that act as compasses and motors, guiding the divisions of ...

Genetic Adaptation to Climate Change Is Swift in Crop Pests

By comparing genetic variants differing in the two fly populations, researchers found that polygenic traits led to the quickness of adaptation; many genes, each with very small effects, worked ...

Engineered Bacteria Churn out Cancer Biomarkers

Pity the glycan. A lab has created these very tools by commandeering simple, single-celled microorganisms - namely E. coli bacteria - and engineering them to explore the complex process of ...

Plant Nutrient Delivery Breakthrough

The collaboration revealed that the symbiotic relationship between plants and fungi provides nitrates to plants, which could lead to reduced fertilizer ...

Discovery of Microbes With Mixed Membranes Sheds New Light on Early Evolution of Life

Current research suggests that more complex life-forms, including humans, evolved from a symbiosis event between bacteria and another single-celled organism known as archaea. However, evidence of a ...

Researchers Discover How Worms Pass Down Knowledge Through the Generations

Researchers have discovered that the microscopic roundworm Caenorhabditis elegans recognizes a small RNA made by a pathogenic bacterium, and uses that RNA to convey learned avoidance of the bacterium ...

Social Distancing and Microbial Health

Social distancing is a key component of the expert-recommended strategy to reduce the spread of COVID-19. Avoiding contact with others, however, may have repercussions in a person's gut ...

Scientists Explaining How Diverse Species Coexist in Microbial Communities

Researchers use mathematical modeling to explore how species diversity in a bacterial community is affected when the nutrients the microbes depend upon are only seasonally ...

Scientists Identify Gene Family Key to Unlocking Vertebrate Evolution

New research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode ...
