Hair Whorl Direction Influenced by Multiple Genes

The first gene mapping study on human scalp hair whorls not only demonstrates that hair whorl direction has a genetic basis but also that it is influenced by multiple genes.

Parasites Found in 200-Million-Year-Old Fossilized Feces

Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a study published August 9, 2023 in the open-access journal PLOS ONE by Thanit Nonsrirach of Mahasarakham University, Thailand and colleagues.

The “Unknome” Dataset Contains Protein Sequences That Are Still Unknown

Researchers from the UK anticipate that a new, freely accessible database they have developed will get smaller rather than bigger over time. This is due to the fact that it is a compilation of the many understudied proteins that are encoded by genes in the human genome, whose existence is recognized but whose activities are mostly unknown.

Genetic Analysis of Stone Age Europeans Reveals Complex Intermingling of Groups

A new DNA study has nuanced the picture of how different groups intermingled during the European Stone Age, but also how certain groups of people were actually isolated.

Bacteria Have Complex Circadian Clocks, Study Finds

Bacteria make up more than 10% of all living things but until recently we had little realization that, as in humans, soil bacteria have internal clocks that synchronize their activities with the 24-hour cycles of day and night on Earth.

Malaria Parasite’s Meiosis Could Hold the Key to New Treatments

Researchers from the Universities of Leicester and Nottingham have been awarded nearly £600,000 to investigate how sexual development and gene shuffling inside the malaria parasite can help regulate malaria transmission.

Determining a Network of Cellular Programs Controlling Human Cancers

A Ludwig Cancer Research study has identified a pair of genes whose expression by a type of immune cell within tumors is predictive of outcomes for cancer patients and is linked to a vast network of gene expression programs, engaged by multiple cell types in the tumor microenvironment, that control human cancers.
