Researchers show how the genetic material travels from cell to cell

The genetic material of plants, animals, and humans is well protected in the nucleus of each cell and stores all the information that forms an organism. For example, information about the size or color of flowers, hair or fur is predefined here.

Researchers discover new way to control natural killer cells in immune system

UC San Francisco scientists have discovered a new way to control the immune system's "natural killer" (NK) cells, a finding with implications for novel cell therapies and tissue implants that can evade immune rejection.

Proteogenomic study may lead to more effective treatments for head and neck squamous cell carcinoma

Proteogenomic studies may provide a better understanding of how to match cancer patients with an effective treatment for their specific cancer.

Scientists trace back evolutionary history of antibiotic resistance genes

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.

Study uncovers unusual sex chromosomes of Australian iconic animals

The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually, appear as one pair of morphologically different chromosomes between sexes.

New technique to detect gene doping in human plasma

All athletes wish to be at the top of their game while competing, yet some turn to corrupt strategies to achieve peak speed, agility, and muscle growth. Latest advancements in gene editing technology could lure athletes to change their DNA to gain an upper hand.

Scientists identify gene that helps rice adapt to low soil nitrogen

Chinese researchers from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) have identified a gene that plays a significant role in helping rice adjust to low nitrogen levels in soil.

Study may lead to new treatments for autoimmune diseases

According to a research team, headed by Decio L. Eizirik, MD, PhD, a Scientific Director from the Indiana Biosciences Research Institute Diabetes Center, new treatments for autoimmune disorders can be identified by studying both target tissues and the immune system together.

Researchers map platypus genome to understand its bizarre characteristics

Often considered the world's oddest mammal, Australia's beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes.

Study explores why Shiga toxin-producing E. coli infections are so dangerous

E. coli food poisoning is one of the worst food poisonings, causing bloody diarrhea and kidney damage. But all the carnage might be just an unintended side effect, researchers from UConn Health report in the 27 November issue of Science Immunology. Their findings might lead to more effective treatments for this potentially deadly disease.

Study addresses mystery of how chromosomes are inherited during cell division

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.

DNA-editing technique used to extend lifespan of mice with progeria

Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy.

Longitudinal study identifies many genetic markers linked to bone mineral accrual

A multidisciplinary team of researchers led by Children's Hospital of Philadelphia has discovered several genetic markers associated with bone mineral accrual, which could ultimately help identify causes of eventual osteoporosis earlier in life through genetic testing.

Scientists resolve long-standing debate over key mechanism involved in gene silencing

Scientists from Massachusetts General Hospital (MGH) have resolved a long-standing debate over how crucial gene-silencing protein detects its targets.

New study explores the role of genetics in prostate cancer

When compared to other groups, certain ethnic and racial groups tend to suffer more often, and fare worse, from common ailments.

New project on self-deleting gene technology takes aim at mosquito populations

To control mosquito populations and prevent them from transmitting diseases such as malaria, many researchers are pursuing strategies in mosquito genetic engineering. A new Texas A&M AgriLife Research project aims to enable temporary "test runs" of proposed genetic changes in mosquitoes, after which the changes remove themselves from the mosquitoes' genetic code.

Genomic study of weedy seadragons reveals significantly distinct populations

Charismatic, iconic and Instagram-friendly, the weedy seadragon is a favourite with divers and snorkellers. The first genomic study of east coast Australian seadragon populations can now reveal "weedies" from NSW, Victoria and Tasmania are significantly different.

Study uncovers how shattered chromosomes make cancer cells more aggressive

Cancer is one of the world's greatest health afflictions because, unlike some diseases, it is a moving target, constantly evolving to evade and resist treatment.

Researchers use different colors of light to control gut bacteria genes

Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her lab by as much as 50%, but her collaboration with Rice University synthetic biologist Jeffrey Tabor is providing tools to answer the bigger question of how the metabolite imparts longer life.

Scientists find master switch that adjusts gene activity to match nutrient levels in roundworms

Transforming a fertilized egg into a fully functional adult is a complicated task. Cells must divide, move, and mature at specific times. Developmental genes control that process, turning on and off in a choreographed way.
