Ancient DNA reveals African founders intermingled with southwest Asian people around 1000 CE

While serfs toiled and knights jousted in Europe and samurai and shoguns rose to power in Japan, the medieval peoples of the Swahili civilization on the coast of East Africa lived in multicultural, coral-stone towns and engaged in trade networks spanning the Indian Ocean.

Single monoclonal antibody infusion can strengthen the body's fight against yellow fever

New research from Oregon Health & Science University and collaborators indicates lab-made antibodies may be able to cure people infected with yellow fever, a virus for which there is no treatment.

COVID-19 vaccines boost the levels of T cells in immunocompromised hematology patients

Researchers found that, despite being heavily immunocompromised, hematology patients generate strong cellular immune responses against SARS-CoV-2 after vaccination, on par with that of healthy individuals.

FDA-approved compound promotes photoreceptor survival in lab models of inherited retinal ciliopathy

A National Eye Institute-led team has identified a compound already approved by the U.S. Food and Drug Administration that keeps light-sensitive photoreceptors alive in three models of Leber congenital amaurosis type 10 (LCA 10), an inherited retinal ciliopathy disease that often results in severe visual impairment or blindness in early childhood.

SARS-CoV-2 infection hijacks and damages parts of infected cells' vital RNA machinery

Coronavirus disease (COVID-19) hijacks parts of infected cells' vital RNA machinery, thereby blocking important functions in the cells. These damaging changes in the RNA can likely be reversed, potentially leading to new drugs against COVID-19, University of Gothenburg researchers show.

Study reports a new target to fight against antibiotic-resistant pneumonia

Increases in multidrug-resistance in the bacteria Streptococcus pneumoniae have made it the fourth-leading cause of death associated with antibiotic resistance.

Study expands understanding of PAK1-related IDDMSSD

A recent study from Texas Children's Hospital and Baylor College of Medicine has expanded the clinical spectrum of a new epileptic disorder called Intellectual Developmental Disorder with Macrocephaly, Seizures, and Speech Delay (IDDMSSD) with the identification of the first recurrently affected residue identified in the protein kinase domain of PAK1 protein.

Two subtypes of cells that produce insulin discovered

A team of scientists from the Van Andel Institute and the Max Planck Institute for Immunobiology and Epigenetics uncovered two unique subtypes of insulin-producing beta cells, or ß cells, each having important traits that could potentially be used to better understand and treat Type 1 and Type 2 diabetes.

Artificial cells to serve as the powerhouse of the future

Chloroplasts and mitochondria are responsible for producing energy in nature, which is essential for creating sustainable, artificial cells in the lab. In addition to being “the powerhouses of the cell,” as the adage from middle school biology goes, mitochondria are also one of the most difficult intracellular components to artificially clone.

Epigenetic fingerprinting helps trace the origin of animal products

Food analysis laboratories can provide an answer to questions like “Was the salmon for dinner really caught wild or did it come from aquaculture? What to make of the alleged ‘biolabel quality’ of the shrimp for the seafood salad? And was the chicken for the Sunday roast really allowed to spend its life in the open air?” to a limited extent.

Novel inhibitor, hopeaphenol, blocks HIV expression

In the United States, around 1.2 million people are living with HIV as of 2022. Many of these people can now live productive, symptom-free lives thanks to antiretroviral therapies, but a solution that permanently removes HIV from an infected person’s body is still a long way off.

Genetic welding: Evolutionary meddling with genes

With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations.

Cocklebur fruit shows potential to protect the skin and help enhance collagen production

The fruit of the cocklebur plant, which grows worldwide and is often considered a noxious weed, has antioxidant and anti-inflammatory components that could make it useful as a skin protectant, according to new research.

Using better probiotics to maintain a healthy gut microbiome

Bacteria have thousands of genes and functions that we, the human host, do not have. For instance, bacteria can help us digest fiber, provide support to our immune systems, and absorb important nutrients. But reaping the benefits of "good bacteria" is easier said than done.

Additional therapeutic maneuver may be needed to stop some metastasized tumors Cancer That...

Cancer that has spread to areas like the lungs can apply the brakes to a natural pathway that should recruit killer T cells directly to where it has metastasized, scientists report.
