DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Cellular reprogramming can lead to better liver tissue regeneration in mice

Mammals can't typically regenerate organs as efficiently as other vertebrates, such as fish and lizards. Now, Salk scientists have found a way to partially reset liver cells to more youthful states - allowing them to heal damaged tissue at a faster rate than previously observed.

Discovery about human cells’ stress response could deepen the understanding of various cancers

The communications line between two critical parts of a human cell could be the key to cell survival under stress - a discovery that could deepen our understanding of various cancers, according to new research from the University of Surrey.

Johns Hopkins scientists receive $7.8 million funding from Break Through Cancer

The Johns Hopkins Kimmel Cancer Center and the Departments of Gynecology/Obstetrics, Neurosurgery and Pathology have been awarded more than $7.8 million for novel, multicenter projects designed to intercept and find cures for several deadly cancers, including pancreatic cancer, ovarian cancer, and the brain cancer known as glioblastoma.

Exploring Populations of B and T Cells in Lymph Nodes of Patients Diagnosed with COVID-19 via Microscopy and Image Analysis

My work is focused on looking at the dynamics of B/T cell populations within lymph nodes from patients that had recovered from COVID-19. My role in this research was developing and implementing microscopy image analysis techniques using methods and instrumentation in part supplied by TissueGnostics.

Disease-causing amoebas that live on organic leafy vegetables could be a threat to public health

New research to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases in Lisbon, Portugal (23-26 April), suggests that disease-causing amoebas that live on organic leafy vegetables can shelter human pathogens like Pseudomonas, Salmonella, and Helicobacter and are a potential risk to public health.

Novel methods for inferring the movement of brain cells during fetal development

The making of a human brain remains a mostly mysterious process that races from an embryonic neural tube to more than 100 billion interconnected neurons in the brain of a newborn. To achieve this marvel of biological engineering, the developing fetal brain must grow, on average, at a rate of roughly 250,000 nerve cells per minute throughout the course of a pregnancy.
