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.

New protocol identifies mismatch repair deficiency

Researchers have developed a new integrated genetic/epigenetic DNA-sequencing protocol known as MultiMMR that can identify the presence and cause of mismatch repair (MMR) deficiency in a single test from a small sample of DNA in the colon, endometrial, and other cancers.

Cancer cells can exchange and recombine their genetic material, shows study

Evolution within groups of tumor cells follows the principles of natural selection, as evolution in pathogenic microbes.

Study defines the most crucial genes that Increase risk of breast cancer

Genetic inheritance affects the likelihood of developing breast cancer. Some genes are already known to increase cancer risk; other genes are suspected to be involved, but not to what extent. It is crucial to clarify this issue to improve prevention since it opens the way to more personalized follow-up and screening programs.

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.

Venom of Tiger Rattlesnakes may advance genetic science

Among all rattlesnake species, the Tiger Rattlesnake has the simplest yet most lethal venom. Now, a new study performed by a team of researchers can describe the genetics behind the venomous bite of the Tiger Rattlesnake.

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.

Investigational antisense medicine lowers disease burden, reduces myeloma cell abundance in mice

Many patients with multiple myeloma, a type of blood cancer, eventually develop resistance to one treatment after another. That's in part because cancer stem cells drive the disease -- cells that continually self-renew. If a therapy can't completely destroy these malignant stem cells, the cancer is likely to keep coming back.

Researchers discover genetic risk factor for stroke

A research team from Geisinger Health System has detected a common genetic variant as a risk factor for stroke, particularly in patients aged more than 65.

Study reveals genetic variants that increase the risk of nocturnal enuresis

In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.

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.

New computational technique accurately differentiates between normal and cancer cells

Scientists have created a new method to precisely differentiate between data from a wide range of normal cells and cancer cells found inside tumor samples.

New genome resource helps study genetic traits in major crops

Thanks to a new genome resource created for green millet, researchers will be able to study the genetics of crucial traits in crops, like sorghum and maize, in a much better way. The resource was created by three RIKEN scientists.

Gene therapy helps paralyzed mice to walk again

For the first time, scientists have successfully used gene therapy to make mice walk again after these animals suffered a complete cross-sectional injury.

Study shows how specific gene mutations cause different types of diseases

Renowned cancer experts have resolved a query of how different types of mutations in a single gene are responsible for causing various types of diseases.

Researchers make new discovery in the quest for novel antibiotics

Scientists who highlighted the bug-busting properties of bacteria in Northern Irish soil have made another exciting discovery in the quest to discover new antibiotics.

Researchers use heat map data to reverse engineer chromosome models

Genome analysis can provide information on genes and their location on a strand of DNA, but such analysis reveals little about their spatial location in relation to one another within chromosomes -- the highly complex, three-dimensional structures that hold genetic information.

Speciation process takes place in the presence of maximal gene flow, indicates study

Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.
