Scientists discover trigger that turns strep infections into devastating disease

Houston Methodist infectious disease scientists have discovered a previously unknown trigger that turns a relatively run-of-the-mill infection into a devastatingly ravenous, flesh-eating disease.

Columbia researchers unravel why some glioblastomas respond to immunotherapy

Columbia researchers have learned why some glioblastomas--the most common type of brain cancer--respond to immunotherapy. The findings could help identify patients who are most likely to benefit from treatment with immunotherapy drugs and lead to the development of more broadly effective treatments.

Whole-genome sequencing and sharing real-time data could limit spread of foodborne bacteria

Employing advanced genetic-tracing techniques and sharing the data produced in real time could limit the spread of bacteria -- Bacillus cereus -- which cause foodborne illness, according to researchers who implemented whole-genome sequencing of a pathogen-outbreak investigation.

Photoacoustic imaging accurately measures the temperature of deep tissues

Measuring a fever is usually pretty simple: place a thermometer under a patient's tongue and get an accurate temperature reading within 30 seconds. But that simplicity does not translate when it comes to measuring the temperatures of specific tissues deep inside the body.

Novel approach uses small amounts of tissue to quantify PD-L1 expression levels in tumors

Immune checkpoint inhibitors, such as the anti-PD-1 antibody pembrolizumab, have become important tools for managing non-small-cell lung cancer.

Increased activity of EHMT2 gene deficient neurons could cause autism in humans

A novel investigation into the impacts of neuronal mutations on autism-related characteristics in humans has been described in the open-access journal eLife.

Relapse dreams more common in people with severe alcohol, drug addiction history

Vivid dreams involving drinking and drug use are common among individuals in recovery. A study from the Massachusetts General Hospital Recovery Research Institute, published in the January issue of the Journal of Substance Abuse Treatment after online release in October 2018, finds these relapse dreams are more common in those with more severe clinical histories of alcohol and other drug problems.

Mountain chickadee research shows link between natural selection and spatial memory

Chickadees with better learning and memory skills, needed to find numerous food caches, are more likely to survive their first winter, a long-term study of mountain chickadees has found.

New process efficiently reprograms stem cells in one step using measles virus vector

Induced pluripotent stem cells, the workhorse of many regenerative medicine projects, start out as differentiated cells that are reprogrammed to pluripotent stem cells by exposure to a complex set of genetic cocktails.

Comparison of cancer genes across species helps prioritize targets for new cancer therapies

Cancer genes in mucosal melanoma, a rare and poorly understood subtype of melanoma, have been compared in humans, dogs and horses for the first time by scientists at the Wellcome Sanger Institute and their collaborators.

NIH scientists zero in on genes associated with AMD

National Eye Institute scientists led a collaborative study and zeroed in on genes associated with age-related macular degeneration, a leading cause of vision loss and blindness among people age 65 and older.

MGH researchers identify brain cells that modulate behavioral response to threats

A team of investigators from the Massachusetts General Hospital (MGH) Center for Regenerative Medicine has identified a population of brain cells that appears to play a role in calibrating behavioral responses to potentially threatening situations.

Research reveals critical immunological axis that triggers cancer-promoting chronic inflammation

A Massachusetts General Hospital research team has identified interaction between two elements of the immune system as critical for the transformation of a protective immune response into chronic, cancer-promoting inflammation.

Scientists develop machine-learning approach to identify source of Salmonella

A team of scientists led by researchers at the University of Georgia Center for Food Safety in Griffin has developed a machine-learning approach that could lead to quicker identification of the animal source of certain Salmonella outbreaks.

Individualized diets more effective in controlling blood glucose levels, study finds

An individualized diet based on a person's genetics, microbiome and lifestyle is more effective in controlling blood glucose (sugar) levels than one that considers only nutritional composition of food, Mayo Clinic researchers have confirmed.

When genomic sequencing fails to diagnose a rare disease

Routine sequencing has given unprecedented insight into the genetics of rare diseases, but genomics fails to diagnose up to half of patients who are tested. That's the problem German scientists tackled in a recent study in the journal Molecular & Cellular Proteomics.

Scientists develop novel way with genome sequences to study widespread form of malaria

Scientists at the Institute of Genome Sciences at the University of Maryland School of Medicine have developed a novel way with genome sequences to study and better understand transmission, treat and ultimately eradicate Plasmodium vivax, the most widespread form of malaria. P. vivax is a single-celled transmitted by mosquitoes.

RNAs are involved in protein aggregation and neurodegenerative diseases, research reveals

New research reveals RNAs, which are crucial for cells to produce proteins, are also involved in protein aggregation, where proteins do not fold properly and 'clump' together into aggregates. If cells cannot clear these away, they become toxic and prevent cells working properly.

Increase in vocal-cord cancers among young adults appears to be the result of HPV infection

A remarkable recent increase in the diagnosis of vocal-cord cancer in young adults appears to be the result of infection with strains of human papilloma virus that also cause cervical cancer and other malignancies.

Cloning-free Nested CRISPR uses long DNA fragments for efficient gene editing

CRISPR is a technique that is revolutionizing biomedical research through high-precision genome editing. However, even though it allows the creation or correction of mutations consisting of a single or few nucleotides with relative ease, it still possesses limitations upon introducing larger fragments of DNA in the genome.
