Digging ancient signals out of modern human genomes

A recent study in Molecular Biology and Evolution reconstructed artificial genomes with the analyses of 565 contemporary South Asian individuals to extract ancient DNA signals. The researchers found valuable genetic components that allow them to elucidate the genetic composition of ancient populations in the region. Additionally, they ...

Defining the responsibility to recontact research participants with new genetic findings

The American Society of Human Genetics has issued a position statement outlining the responsibility to recontact research participants with new genetic findings. The statement recommends that researchers make reasonable attempts to recontact participants if the reinterpretation is expected to affect medical management, but not strongly...

Great white shark genome decoded

The study found that the great white shark's genome contains a plethora of genetic changes indicating molecular adaptation in genes with important roles in maintaining genome stability, DNA repair, and DNA damage tolerance. These adaptations could be behind the evolutionary success of large-bodied and long-lived sharks.

Elevated hormone flags liver problems in mice with methylmalonic acidemia

Researchers have discovered a hormone, fibroblast growth factor 21 (FGF21), is extremely elevated in mice with liver disease mimicking methylmalonic acidemia. FGF21 levels can predict liver severity and inform treatment decisions. The study may also shed light on common disorders like fatty liver disease and obesity.

Getting a grip on the slow but unique evolution of sharks

Researchers analyzed two shark species' genomes and compared them to those of vertebrate species to understand their evolution. They found that sharks have massive insertions of repetitive elements in their genomes, which may contribute to their slow evolution.

An international team led by the CNIO reveals that human genome could contain up to 20 percent fewer genes

A new international collaboration led by the CNIO reveals that up to 20% of human genes may not be coding genes, but rather non-coding or pseudogenes, which could have significant effects on biomedicine. The study analyzed gene catalogs and found that many genes were more likely to be non-coding than previously thought.

How gene hunting changed the culture of science

Researchers report cross-disciplinary work as key factor in HGP's success, leading to more successful careers and impactful publications. The consortium model, which incorporated collaboration between biologists, computer scientists, and other disciplines, changed science's cultural norms.

Improved ape genome assemblies provide new insights into human evolution

New, high-quality ape genome assemblies have been generated without the guidance of the human reference genome, providing a clearer view of genetic differences that arose as humans diverged from other primates. The research team also studied brain organoids to understand how differences in gene expression during brain development might...

Blueprint for the skull

A study published in Cell Reports has mapped the genetic regulators of facial development, revealing thousands of previously unknown enhancers linked to craniofacial abnormalities. The researchers found that these enhancers contribute to many cases of cleft palate and provide new insights into the causes of this birth defect.
