Study shows DNA damage causes cells to reprogram themselves into stem cells

Researchers have discovered that when DNA in the moss Physcomitrella patens is damaged, it causes cells to reprogram on their own to change into stem cells.

Scientists identify complex enzyme that protects cells from constant DNA damage

A team of researchers have revealed the mechanism and 3D structure of a complex enzyme that guards cells against persistent DNA damage.

Researchers detect robust T cell response in patients with mild COVID-19 infection

Mild cases of COVID-19 pandemic can activate strong responses from memory T cells, even when detectable virus-specific antibody responses are absent.

'Survival of the fittest': How meiotic drivers shape the evolution of gamete formation

It can be hard to dispute the common adage 'survival of the fittest'. After all, "most of the genes in the genome are there because they're doing something good," says Sarah Zanders, PhD, assistant investigator at the Stowers Institute for Medical Research

Study shows how mitochondrial defects lead to neurodevelopmental diseases

The tiny organelles mitochondria supply the energy crucial for all cells in the human body, specifically in the brain that consumes an excessive amount of fuel.

Study shows how proteins act as a defense mechanism to protect their own DNA

Viruses usually inject their DNA into a host cell to multiply. As soon as this foreign material penetrates the intracellular fluid, it activates a defense mechanism called the cGAS-STING pathway.

Study shows how viruses escape the immune system

Scientists from the University of Otago have gained a deeper understanding of how viruses work and escape the immune system. The team is presently using this finding to find out more about the COVID-19 pandemic.

Ultra-low voltage electricity effectively damages and kills bacteria

Ultra-low voltage electricity is effective at killing bacteria because it causes membranes that surround bacteria to leak, according to a new study by University of Arkansas researchers. The research advances work to fight drug-resistant bacteria.

New discovery offers hope for people at risk of antibiotic-resistant infections

There is new hope for approximately 700,000 people who die each year from antibiotic resistant infections, with University of Queensland researchers discovering how bacteria share antibiotic-resistance genes.

High-speed AFM enables real-time visualization of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

Extrachromosomal DNA with potential to cause cancer drives poor patient outcomes

The multiplication of genes located in extrachromosomal DNA that have the potential to cause cancer drives poor patient outcomes across many cancer types, according to a Nature Genetics study published Aug. 17, 2020 by a team of researchers including Professors Vineet Bafna and Dr.Paul Mischel of the University of California San Diego and Professor Roel Verhaak of Jackson Laboratories.

Regulating cancer stemness using combination of nanotechnology and genetic engineering

The development of chemotherapeutic agents with selective anti-cancer activities is increasingly unattractive due to the emergence of resistance, poor targeting of cancer tissues, and subsequent metastasis.

Rotating microscope can track and measure behavior of ocean organisms

Like spirits passing between worlds, billions of invisible beings rise to meet the starlight, then descend into darkness at sunrise. Microscopic plankton's daily journey between the ocean's depths and surface holds the key to understanding crucial planetary processes, but has remained largely a mystery until now.

Novel receptor protein can be a promising treatment for COVID-19

A novel receptor protein that binds to the SARS-CoV-2 virus and prevents it from entering cells may hold promise for treating COVID-19 and other coronavirus-related diseases, according to research published online Aug. 4 in the journal SCIENCE.

Researchers show how two X chromosomes communicate during embryo development

Researchers at Massachusetts General Hospital (MGH) have solved a mystery that has long puzzled scientists: How do the bodies of female humans and all other mammals decide which of the two X chromosomes it carries in each cell should be active and which one should be silent?

SIDT1 in the mammalian stomach mediates absorption of dietary miRNAs

In a new study published in Cell Research, Chen-Yu Zhang's group at Nanjing University School of Life Sciences, China, reports that SIDT1 in the mammalian stomach mediates host uptake of dietary and orally administered microRNAs (miRNAs), thus exerting biological functions in the host.
