Study reveals that bacteria DNA signals can be read either forward or backward

Bacteria’s DNA signals have symmetry that allows them to be read either backward or forward, challenging the current understanding of gene transcription.

Routine cleaning and sanitation are key to prevent microbial contamination in food products

Spoilage and foodborne illness could be reduced by using specially designed rapid-testing ATP swabs to clean surfaces in commercial food processing facilities.

Research uncovers how antibiotics target bacterial RNA Polymerase to inhibit gene transcription

The emergence and spread of new forms of resistance remains a concern that urgently demand new antibiotics. Transcription is a vital process in bacterial cell, where genetic information in DNA is transcribed to RNA for the translation of proteins that perform cellular function.

High-tech laboratory methods to explain how endophytic bacteria would live within plant cells

Scientists have explained how healthy plants tend to hold bacteria in their cells, opening up a new area of research to enhance potential plant health.

Study finds how SARS-CoV-2 hijacks human cell machinery to disrupt the immune response

SARS-CoV-2 hijacks human cell machinery to disrupt the immune response, enabling it to cause infection, replicate, and cause disease.

Researchers describe the internal anatomy of marine worm

The marine worm Ramisyllis multicaudata, which lives within the internal canals of a sponge, is one of only two such species possessing a branching body, with one head and multiple posterior ends.

Distinctive "spike" proteins of SARS-CoV-2 also play a key role in the disease

Scientists have known for a while that SARS-CoV-2's distinctive "spike" proteins help the virus infect its host by latching on to healthy cells.

Bacterial species in the soil can evolve with climate change

While evolution is normally thought of as occurring over millions of years, researchers at the University of California, Irvine have discovered that bacteria can evolve in response to climate change in 18 months.

Processed diet reduces gut bacteria and promotes encroachment of microbiota into the intestine

Processed diets, which are low in fiber, may initially reduce the incidence of foodborne infectious diseases such as E. coli infections, but might also increase the incidence of diseases characterized by low-grade chronic infection and inflammation such as diabetes, according to researchers in the Institute for Biomedical Sciences at Georgia State University.

SDIR1 enzyme plays a major role in the expression of defense gene in plants

A new study offers evidence that microbes are trying to hijack the plant immune system to induce disease while also offering insights into a new mechanism.

New AI model predicts targets for previously unmapped T cells against coronavirus

A research team has created an AI technique that can bind immune cells to their targets and uncouple the types of white blood cells that identify SARS-CoV-2.

Natural molecule can effectively block the binding of human antibodies to SARS-CoV-2

Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

SARS-CoV-2 infection produces antibodies that can destroy infected cells

Research teams investigated the antibodies generated in people with symptomatic or asymptomatic SARS-CoV-2 infection.

Study identifies mechanism that enables SARS viruses to efficiently replicate in infected cells

Researchers have now identified how SARS viruses improve the production of viral proteins in infected cells such that new copies of the virus can be produced.

Study offers new ways to think about the immune system

Scientists have discovered new methods to interpret the immune system, as part of a new study reported in the Nature journal.

Sampling environmental DNA and RNA could help determine the presence of pathogens

Conventional techniques lack the potential to easily sample wider geographical areas and huge numbers of individuals.

Antibodies may not inhibit SARS-CoV-2 variants from minks

It has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry of the virus into host cells and represents the central point of attack for antibodies.

Supercomputer simulations reveal the behavior of dominant G form SARS-CoV-2 strain

Large-scale supercomputer simulations at the atomic level show that the dominant G form variant of the COVID-19-causing virus is more infectious partly because of its greater ability to readily bind to its target host receptor in the body, compared to other variants.
