Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

Discovery of genes lending tolerance to sugarcane from pests, cold, and drought

Saccharum spontaneum, a species of wild sugarcane with exceptional resistance to biotic stresses like nematodes, fungi, bacteria, and other pests and diseases, as well as abiotic stresses like cold, drought, salinity, and nutritionally deficient soil, was the subject of a study at the State University of Campinas (UNICAMP) in Brazil.

World's terrestrial plant, animal life could already be at greater risk from genetic diversity loss

Climate change and habitat destruction may have already caused the loss of more than one-tenth of the world's terrestrial genetic diversity, according to new research led by Carnegie's Moises Exposito-Alonso and published in Science.

Chromosome restructuring suppresses meiotic recombination

The use of CRISPR/Cas (Clustered Regularly Interspaced Short Palindromic Repeats) molecular scissors enables targeted editing, insertion, or suppression of genes in plants.

Common genetic variants associated with beat synchronization identified

The first large-scale genomic study of musicality revealed 69 genetic variations linked with beat synchronization, which denotes the ability to move in time with the beat of the music.

Researchers reveal key developmental difference between the brains of modern humans and Neanderthals

AZoLifesciences speaks to Dr. Anneline Pinson and Prof. Dr. Wieland B. Huttner from The Max Planck Institute of Molecular Cell Biology and Genetics about their latest research which found a greater neuron production in the frontal lobe during brain development in modern humans than Neanderthals, due to the change of a single amino acid in the protein TKTL1.

Research shows how developing sea anemones essentially 'exercise' to build their morphology

As humans, we know that an active lifestyle gives us some control over our form. When we hit the pavement, track our steps, and head to the gym, we can maintain muscle development and reduce body fat.

Researchers analyze how clusters of molecules meet inside cells

A developing area studies how clusters of molecules gather inside of cells, similar to how oil droplets form and separate from the water in a vinaigrette.

Human-specific gene involves in neocortical expansion during evolution

Great ape animal experiments have long been prohibited in Europe due to ethical concerns. An alternative to using animals in investigations is the use of organoids, which are three-dimensional cell structures that can be generated in the lab and are only a few millimeters in size.

Using the genomes of wild tomato relatives to improve tomato

The relatives of the wild tomato, Solanum habrochaites and S. galapagense, are crucial sources of germplasm in contemporary tomato breeding.

Light-sensitive molecule can interpret moonlight to synchronize the reproductive cycles of marine life

How animals are able to interpret natural light sources to adjust their physiology and behaviour is poorly understood.

Researchers propose a way to identify Chlamydia, a deadly bacterial disease

Chlamydia, the most common bacterial infection associated with sexually transmitted diseases, hides inside human cells using a cloaking mechanism to avoid detection and destruction.

Studies on mice reveals the co-existence of gut bacteria and their hosts

According to scientists, the gut microbiome—a colony of bacteria that inhabits the digestive system—can be altered by the host body’s genes in addition to nutrition and environment.

Novel method maps all gene expression patterns to a single reference embryo

Years of work by Trinity College Dublin developmental biologists in collaboration with colleagues at the University of Edinburgh’s MRC Human Genetics Unit has resulted in an unparalleled resource that will help researchers assess how key genes control the differentiation of tissues and organs in developing embryos.

Researchers face challenges with stem cell lines that carry major DNA damage

Stem cells are a type of cell that can be configured to transform into almost any sort of cell in the body. They are presently used in research on organ development as well as in the initial phases of embryo development.
