New study sheds light on citrus greening disease

Huanglongbing (HLB), also called citrus greening disease, is detrimental to the citrus industry and causes unparalleled levels of destruction around the world. But despite this fact, there is no proven treatment for this.

SARS-CoV-2 virus may enter and replicate in human cells by targeting cellular processes

The SARS-CoV-2 virus may enter and replicate in human cells by exploiting newly-identified sequences within cell receptors, according to work from two teams of scientists.

Researchers identify a new way to stop COVID-19 virus

While the world awaits broad distribution of COVID-19 vaccines, researchers at Ohio University just published highly significant and timely results in the search for another way to stop the virus -- by disrupting its RNA and its ability to reproduce.

Immunity of COVID-19 patients may rely on antibodies from previous coronavirus infections

The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.

Antibiotic resistance may be spreading much faster than expected

Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic transfer between bacteria in our ecosystems and to humans. This work has also led to new tools for resistance researchers.

New technique helps detect dangerous histamine levels in fish samples

For people buying food products, there is no way to determine the safety and quality of food that is delivered to their plates by existing distribution systems.

Viral relatives of SARS-CoV-2 can evolve to evade the human immune system

Scientists have shown that two species of seasonal human coronavirus related to SARS-CoV-2 can evolve in certain proteins to escape recognition by the immune system, according to a study published today in eLife.

Fecal microbiome differs in healthy and food-allergic twins

A new study out of the University of Chicago and Stanford University on pairs of twins with and without food allergies has identified potential microbial players in this condition. The results were published on Jan. 19 in the Journal of Clinical Investigation.

Scientists identify the sensor in human lungs that detects SARS-CoV-2

Scientists at Sanford Burnham Prebys Medical Discovery Institute have identified the sensor in human lungs that detects SARS-CoV-2 and signals that it's time to mount an antiviral response.

Nanobodies can prevent entry of SARS-CoV-2 coronavirus into human cells

Researchers at Karolinska Institutet in Sweden have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells.

Researchers develop novel nanobodies against SARS coronavirus-2

An international research team led by the University of Bonn has identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are much smaller than the classic antibodies used to treat US President Donald Trump, for example.

Research uncovers gut microbes associated with lower risks of common conditions

Diets rich in healthy and plant-based foods encourage the presence of gut microbes that are linked to a lower risk of common illnesses including heart disease, research has found.

New discovery helps explain how COVID-19 suppresses the body’s immune response

Seeking to understand why COVID-19 is able to suppress the body's immune response, new research from the USC Leonard Davis School of Gerontology suggests that mitochondria are one of the first lines of defense against COVID-19 and identifies key differences in how SARS-CoV-2, the virus that causes COVID-19, interacts with mitochondrial genes when compared to other viruses.

Study unravels the mystery of infectious virion formation

Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus 'package up' their genetic code, allowing them to infect cells.

Advanced nanomaterial-based biosensing platform detects COVID-19 antibodies within seconds

Researchers at Carnegie Mellon University report findings on an advanced nanomaterial-based biosensing platform that detects, within seconds, antibodies specific to SARS-CoV-2, the virus responsible for the COVID-19 pandemic.

Sequencing-based solution can help determine patients’ response to infection therapy

Scientists from the University of Helsinki have created a new sequencing-based strategy for identifying pathogens from complex samples.

Scientists trace back evolutionary history of antibiotic resistance genes

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.
