Theobroma cacao is the most economically important species within the genus Theobroma. Despite its importance, the intraspecific relationships of this species has not been fully elucidated due to insufficient molecular information. To facilitate a better understanding of the intraspecific evolutionary relationships of T. cacao, Sequencing technology has been to decode the plastid genomes, with the objective of…

Evolution has equipped us with a triage mechanism (from the French verb 'trier' meaning to sort out): When there is a deficiency of micronutrients in our bodies, they are reserved for short-term survival and reproduction at the expense of disabling DNA repair, which increases the risk of developing chronic disease in the long-term.

Researchers have identified a range of genetic alterations that may lead to resistance to KRAS G12C inhibitors in patients with KRAS G12C–mutant colorectal and pancreatic cancers.

But more diverse studies have found more genomic links to seizure conditions

Increased BMI contributed to a higher risk for PCOS, and conversely, the severity of PCOS affected the BMI in an analysis of genome-wide association data.

A study published in Genome Biology opens new possibilities to improve production efficiency in the cattle industry and potentially animal agriculture more broadly. A team of researchers at Baylor College of Medicine, Cornell University and the USDA discovered that, like humans, cattle have CoRSIVs.

Men have taste receptors on the testicles in their scrotums.

In spring 2023, Peyton Robb realized an infection might cost him his leg -- or his life. Now, he's trying to win an NCAA title.

An international team of paleontologists from The Netherlands, the UK, Argentina, Germany and Belgium applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phylogenetic analysis, discriminant analysis as well as machine learning.

Scientists have identified five cryptic species of the venomous viper genus Bothriechis living in the jungles and cloud forests of Colombia and Ecuador.

What kind of cancer does HPV cause? Cervical cancer rates are rising among women in their 30s and early 40s, a new report finds.

Extending the limit could help uncover causes of recurrent miscarriage and congenital conditions, experts say

Today, thanks to new artifacts and technologies, findings about our closest relatives are coming thick and fast

A study published in Diversity provides new insight into how toothed whales and dolphins came to navigate the underwater world using sound waves.

Traditional fermented milks are produced by the inoculating technique, which selects well-adapted microorganisms that have been passed on through generations. Few reports have used naturally fermented milks as model ecosystems to investigate the mechanism of formation of intra-species microbial diversity.

True altruism is rare behavior in animals, but a new study by Penn State researchers has found that honey bees display this trait. Additionally, they found that an evolutionary battle of genetics may determine the parent from whom they inherit it.

Scientists in Japan are leaders in the development of new technology that could make sperm and eggs from practically any cell in the body. The results could transform human reproduction.

After the attack in Jupiter, Florida, animal control picked up the otter and it tested positive for rabies, a disease that can be fatal. Here's how it is handled.

The US Centers for Disease Control and Prevention estimates that 97% of people in the U.S. have some immunity to COVID-19 through vaccination, infection or both.

Africa-specific genetic variation on chromosome 1 near CHD1L is associated with HIV replication in vivo.
