Cell Aging Can Be Slowed by Oxidants

At high concentrations, reactive oxygen species - known as oxidants - are harmful to cells in all organisms and have been linked to aging. But a new study, has now shown that low levels of the ...

Discovery of Shape of the SARS-CoV-2 Genome After Infection Could Inform New COVID-19 Treatments

Scientists have uncovered how the genome of SARS-CoV-2 -- the coronavirus that causes COVID-19 -- uses genome origami to infect and replicate ...

Model of Multicellular Evolution Overturns Classic Theory

Cells can evolve specialized functions under a much broader range of conditions than previously thought, according to a ...

Ants Swallow Their Own Acid to Protect Themselves from Germs

Ants use their own acid to disinfect themselves and their stomachs. A team has found that formic acid kills harmful bacteria in the animal's food, thereby reducing the risk of disease. At the same ...

A Key Player Behind Parental Chromosome Matching During Meiosis

Researchers have clarified how homologous chromosome pairing -- a process necessary for sperm and egg formation where paternally- and maternally-derived chromosomes match and exchange genetic ...

How Cell Processes Round Up and Dump Damaged Proteins

Reporting unexpected processes, chemists say they have discovered how an enzyme known as UCH37 regulates a cell's waste management ...

Biologists Create 'Atlas' of Gene Expression in Neurons, Documenting Diversity of Brain Cells

Researchers have created a 'developmental atlas' of gene expression in neurons, using gene sequencing and machine learning to categorize more than 250,000 neurons in the brains of fruit ...

Plant Viruses Hijack the Defense System of Plants, but There Might Be a Way to Strike Back

Recently discovered interactions between plant and viral proteins open up new avenues for making plants resistant to viruses, thus safeguarding crop yields in changing climate ...

Microfluidics Helps Engineers Watch Viral Infection in Real Time

Watching a viral infection happen in real time is like a cross between a zombie horror film, paint drying, and a Bollywood epic on repeat. Over a 10-hour span, chemical engineers from Michigan Tech ...

For Plant and Animal Immune Systems the Similarities Go Beyond Sensing

Researchers have discovered that plants have independently evolved a family of immune proteins that are strikingly similar to ...

'BAH-Code' Reader Senses Gene-Silencing Tag in Cells

Researchers have identified an evolutionarily conserved pathway responsible for 'closing down' gene activity in the mammalian cell. The finding is closely related to the Polycomb pathway ...

How the Immune System Remembers Viruses

For a person to acquire immunity to a disease, T cells must develop into memory cells after contact with the pathogen. Until now, the number of cells that do this was believed to depend above all on ...

Researchers Discover Mechanism That Allows SINEUPs to Amplify Protein Production

Scientists have discovered that a pair of proteins play a key role in allowing an important type of functional non-coding RNA, known as SINEUPs, to act to promote their target messenger ...

Criss-Crossing Viruses Give Rise to Peculiar Hybrid Variants

Biologists investigate a recently discovered class of viruses that have taken the characteristic versatility of the viral world to new heights. Referred to as cruciviruses, these minute forms reveal ...

Beetroot Peptide as Potential Drug Candidate for Treating Diseases

Medical researchers isolated a peptide (small protein molecule) from beetroot. The peptide is able to inhibit a particular enzyme that is responsible for the breakdown of messenger molecules in the ...

Tuning Biomolecular Receptors for Affinity and Cooperativity

Our biological processes rely on a system of communications -- cellular signals -- that set off chain reactions in and between target cells to produce a response. The first step in these often ...

Scientists identified a novel family of sensors in the first layer of cells inside the suction cups that have adapted to react and detect molecules that don't dissolve well in water. The ...

Molecular Compass for Cell Orientation

Plants have veins that transport nutrients through their body. These veins are highly organized. The hormone auxin travels directionally from cell-to-cell and provides cells with positional ...

New Gelatin Microcarrier for Cell Production

Researchers developed a novel microcarrier for large-scale cell production and expansion that offers higher yield and cost-effectiveness compared to traditional methods, and reduces steps required in ...

Mouse Studies Link Some Autism to Brain Cells That Guide Sociability and Platonic Love

Researchers report that new experiments with genetically engineered mice have found clear connections among a range of autism types and abnormalities in brain cells whose chemical output forges ...

Scientists Discover New Organic Compounds That Could Have Helped Form the First Cells

Chemists studying how life started often focus on biopolymers like peptides and nucleic acids, but modern biopolymers don't form easily without help from living organisms. A possible solution to ...

Scientists Map Structure of Potent Antibody Against Coronavirus

Scientists have shown that a potent antibody from a COVID-19 survivor interferes with a key feature on the surface of the coronavirus's distinctive spikes and induces critical pieces of those ...

Scientists Uncover Prophage Defense Mechanisms Against Phage Attacks in Mycobacteria

Researchers have uncovered a two-component system of Butters prophage genes that encode proteins that 'collaborate' to block entry and subsequent infection of some phages, but not others. ...

Not All Mutations Are Bad: Researchers Identify Differences Between Benign and Pathogenic Variants

Researchers have performed a wide-scale characterization of missense variants from 1,330 disease-associated genes. The study identifies features associated with pathogenic and benign variants that ...
