Sequencing-based solution can help determine patients’ response to infection therapy

Scientists from the University of Helsinki have created a new sequencing-based strategy for identifying pathogens from complex samples.

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.

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.

New technological development could revolutionize the dairy industry

Might a new technological development of researchers from Tel Aviv University soon revolutionize the dairy products we consume?

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.

Study shows that hemoglobin in several species descends from a single gene

The marine worm Platynereis dumerilii has enabled researchers from CNRS, Université de Paris, Sorbonne Université, University of Saint Petersburg, and the University of Rio de Janeiro to demonstrate that hemoglobin appeared independently in several species and actually evolved from a single gene transmitted to all by their last common ancestor.

Altered sugar composition impacts cell-to-surface adhesion

Biotechnologists measure the forces with which algae cells adhere to surfaces and move on them. How can cells adhere to surfaces and move on them? This is a question that was investigated by an international team of researchers headed by Prof. Michael Hippler from the University of Münster and Prof. Kaiyao Huang from the Institute of Hydrobiology (Chinese Academy of Sciences, Wuhan, China).

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.

Study reveals evolutionary relationship between two different organelles in liverwort cells

Cells, the basic unit of life, are surrounded by a limiting membrane called the plasma membrane. Inside cells, there are various membrane-bounded organelles, each of which has various and distinctive functions.

A protein encourages cell stickiness during development

Tohoku University scientists have, for the first time, provided experimental evidence that cell stickiness helps them stay sorted within correct compartments during development.

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.

New computational tool can segment and analyze cell images of C. elegans

A joint research team co-led by City University of Hong Kong (CityU) has developed a novel computational tool that can reconstruct and visualise three-dimensional (3D) shapes and temporal changes of cells, speeding up the analysing process from hundreds of hours by hand to a few hours by the computer.

New tantalum-laced composite hydrogel controls excessive bleeding in the body

There are many different events that may lead to excessive and uncontrolled bleeding within the body. This can occur as a result of inflammation and ulcerations, abnormalities in the blood vessels or trauma-related injuries.
