Chaperone protein imbalance initiates toxic accumulation of tau in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

Gaps in understanding kiwi genetics hinder conservation efforts

Kiwi are iconic birds that have been severely impacted by deforestation and predation from invasive mammals since the arrival of humans in New Zealand.

Researchers uncover a key genetic culprit in the development of acute lymphoblastic leukemia

Using a widely known field of mathematics designed mainly to study how digital and other forms of information are measured, stored and shared, scientists at Johns Hopkins Medicine and Johns Hopkins Kimmel Cancer Center say they have uncovered a likely key genetic culprit in the development of acute lymphoblastic leukemia (ALL).

Study shows how tau aggregates promote Alzheimer’s disease

If looked deep into the brain of a patient with Alzheimer’s disease or those suffering from the most types of dementia or the concussion-associated syndrome, called chronic traumatic encephalopathy (CTE), there would be hairball-like tangles of a protein known as tau—a common suspected culprit.

Interferon-stimulating genes control SARS-CoV-2 replication

Researchers have found a set of human genes that combat infection due to SARS-CoV-2, the virus responsible for causing COVID-19.

First-ever global assessment of how climate, land-use change impacts genetic diversity in mammals

Researchers at the University of Copenhagen have made the first ever global assessment map of how future climate and land-use change impacts genetic diversity in mammals. The researchers hope the map will assist policy makers in prioritizing which areas should be preserved first.

New CRISPR technology allows scientists to switch off any gene in human cells

Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.

Study shows how stem cells make specific types of cells

With the help of a novel single-cell technique, researchers from the Walter and Eliza Hall Institute (WEHI) have revealed a new way to interpret the programming behind stem cells and how these cells make specific types of cells.

“Expansion Hunter” approach can detect DNA errors

Researchers from Radboud University Medical Center have successfully detected hidden genetic defects by using an existing technique on existing datasets. The team demonstrated that the “Expansion Hunter” approach can detect DNA errors that cause repeat expansion diseases, like ataxia—a movement disorder.

Researchers use information embedded in microbial genes as a biosensor of ocean health, productivity

Scientists from the University of California, Irvine, analyzed gains and losses in the genes of phytoplankton samples gathered from all major ocean regions to develop the most refined and highest-resolution map that shows where these photosynthetic organisms either survive or are forced to adapt to restricted amounts of main nutrients, nitrogen, iron, and phosphorus.

INRS professor receives $700,000 for research on bacteria of the nasopharynx

Professor Frédéric Veyrier of the Institut national de la recherche scientifique (INRS) has received $711,450 from the Canadian Institutes of Health Research (CIHR) for a project on bacteria of the nasopharynx, including Neisseria.

Study reveals how some antibodies can effectively disable ebolaviruses

Some survivors of ebolavirus outbreaks make antibodies that can broadly neutralize these viruses--and now, scientists at Scripps Research have illuminated how these antibodies can disable the viruses so effectively. The insights may be helpful for developing effective therapies.

Study reveals RNA regulatory mechanisms within transcription-translation couplings

To gain a better understanding of how bacterial RNA gives rise to proteins scientists are now focusing on the special way this process takes place in bacteria.

Ebola virus protein changes shape by using human RNA

The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape--and biologists are taught that defined shape dictates the protein's destined function. Tens of thousands of singular shapes drive the tens of thousands of needed functions.
