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).

Analysis of Complex Genome Interactions Using “GAM”

Eesearchers at the Max Delbrück Center’s Berlin Institute of Medical Systems Biology (MDC-BIMSB) have created a method called Genome Architecture Mapping (“GAM”) to see within the genome and see it in dazzling technicolor.

New Method Provides Near-Perfect Control Over the Manipulation of Individual Molecules

Aleksandra Radenovic, Head of the School of Engineering’s Laboratory of Nanoscale Biology, has spent years working to enhance nanopore technology, which primarily involves a molecule like DNA through a tiny pore in a membrane to quantify an ionic current.

Microglial Cells Serve as a Stable Viral Reservoir for Latent HIV

Human immunodeficiency virus-1 (HIV) introduces a copy of its DNA into human immune cells as part of its life cycle. Some of these newly infected immune cells can subsequently enter an inactive, latent state for an extended length of time, which is known as HIV latency.

Study Offers a New Perspective on the Evolution of Fibonacci Spirals in Plants

Leaf arrangements in the earliest plants differ from most modern plants, overturning a long-held theory regarding the origins of a famous mathematical pattern found in nature, research shows.

Understanding How Genes Predispose Humans to Allergies

New research is expanding the scientific understanding of why some people are more allergic than others. Researchers at the University of Pennsylvania’s Perelman School of Medicine discovered how genetic changes that modify a specific protein called ETS1 can affect our body’s response to allergens.

New Mechanism to Maintain Astrocyte-Neuron Communication

Neurons and astrocytes are the two types of cells required by the brain to enjoy the scent of morning coffee and freshly baked cookies or to discern the warning smell of something burning.

cBAF Protein Complex Controls the Fate of T Cells

The immune system protects the body from intruders, like bacteria, viruses, or tumors, with its intricate network of proteins, cells, and organs. Cytotoxic T cells are specialized immune cells that can grow into short-lived effector cells that destroy infected or malignant cells in human bodies.

Reengineering the Cellular Synthetic Machinery to Produce Never-Before-Seen Polymers

Synthetic biologists have become increasingly creative in engineering yeast or bacteria to churn out useful chemicals -; from fuels to fabrics and drugs -; beyond the normal repertoire of microbes.

Heat-Damaged DNA in Food Linked to Possible Genetic Risks

Researchers have newly discovered a surprising and potentially significant reason why eating foods frequently cooked at high temperatures, such as red meat and deep-fried fare, elevates cancer risk. The alleged culprit: DNA within the food that's been damaged by the cooking process.

Study Provides Evidence for Involvement of p53/p16/RB-E2F-DREAM Repressional Targets in Cellular Senescence

A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 10, entitled, "Key elements of cellular senescence involve transcriptional repression of mitotic and DNA repair genes through the p53-p16/RB-E2F-DREAM complex."

Study Links Timing of Childhood Adversity With Epigenetic Patterns in Adolescents

Childhood adversity-;circumstances that threaten to a child's physical or psychological well-being--has long been associated with poorer physical and mental health throughout life, such as greater risks of developing cardiac disease, cancer, or depression.

Dual CRISPR Gene Drive Systems Target a Specific Gene

According to recent research from North Carolina State University, scientists have created a “homing gene drive system” based on CRISPR/Cas9 that could be used to suppress populations of Drosophila suzukii vinegar flies—so-called “spotted-wing Drosophila” that severely damage soft-skinned fruit in North America, Europe, and parts of South America.

Exploring the Regulatory Mechanism and Physiological Significance of P62 Phosphorylation

Nuclear factor erythroid 2-related factor 2 (NRF2) is a master transcription factor with a role in maintaining oxidative stress response. It can be triggered by both redox-dependent and redox-independent pathways.

A New Method to Escape from Metastability

Prof. Haojun Liang of the Chinese Academy of Sciences’ (CAS) University of Science and Technology of China (USTC) suggested a new way to escape from metastability for self-assembly in a far-from-equilibrium system. The study was published in the journal PNAS.
