Researchers Discover How Common Bacteria can Accelerate Wound Closure in Diabetics

There are many important reasons for keeping cuts and sores clean, but new research from the Perelman School of Medicine at the University of Pennsylvania shows that a certain bug, Alcaligenes faecalis (A. faecalis), can facilitate healing of hard-to-treat wounds among people with diabetes.

Ultrasound-Triggered Nanodroplets for Targeted Drug Delivery

Conventional drug delivery is often like cracking a nut with a sledgehammer. Whether the drug is swallowed, injected, inhaled, or absorbed through the skin, it ultimately diffuses to most parts of the body, including those where it isn’t needed – or where it even might cause harm.

Germ Cells Found to Drive Sex-Dependent Lifespan Differences in Vertebrates

Women live longer than men. This isn't unique to humans, either; we see this trend in a wide range of other animals. Biologists have theorized that the discrepancy in life expectancy between sexes might be partly related to reproduction, but how?

Columbia Studies Uncover Misidentification of Gut Stem Cells

Two independent studies by Columbia scientists suggest that research into the gut's stem cells over the past 15 years has been marred by a case of mistaken identity: Scientists have been studying the wrong cell.

Herpes Gene Therapy Achieves 90% Viral Reduction in Pre-Clinical Studies

Researchers at Fred Hutch Cancer Center have found in pre-clinical studies that an experimental gene therapy for genital and oral herpes removed 90% or more of the infection and suppressed how much virus can be released from an infected individual, which suggests that the therapy would also reduce the spread of the virus.

Transcriptomic Analysis Reveals Age-Dependent Gene Expression Patterns in Mouse Sweat Glands

A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 8, entitled, "Characterization of age-associated gene expression changes in mouse sweat glands."

Rice University Develops AI-Powered Tools for Unraveling Microbial Genomes

Since the first microbial genome was sequenced in 1995, scientists have reconstructed the genomic makeup of hundreds of thousands of microorganisms and have even devised methods to take a census of bacterial communities on the skin, in the gut, or in soil, water and elsewhere based on bulk samples, leading to the emergence of a relatively new field of study known as metagenomics.
