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).

Researchers identify a novel protein that repairs DNA

Researchers from the University of Seville, in collaboration with colleagues from the Universities of Murcia and Marburg (Germany) have identified a new protein that makes it possible to repair DNA.

Scientists discover new method to retrieve lost single-cell RNA-sequencing information

Sequencing RNA from individual cells can reveal a great deal of information about what those cells are doing in the body. MIT researchers have now greatly boosted the amount of information gleaned from each of those cells, by modifying the commonly used Seq-Well technique.

Modification of DNA structure plays key role in the recovery phase after DNA damage

A research team from Cologne has discovered that a change in the DNA structure - more precisely in the chromatin - plays a decisive role in the recovery phase after DNA damage.

3D structural model of BAF complex modifies DNA architecture, provides clues on cancer

Scientists have created an unprecedented 3-dimensional structural model of a key molecular "machine" known as the BAF complex, which modifies DNA architecture and is frequently mutated in cancer and some other diseases.

AncestryDNA modeling study of 500,000 Americans sheds light on COVID-19 risk factors

Now, a new study by researchers at AncestryDNA, a company that provides DNA testing services that use modern autosomal testing technology, shows that some people are more susceptible to COVID-19 infection, and they may experience more severe outcomes, including males, the elderly, and those with comorbidities.

Scientists combine a chemotherapeutic and photodynamic approach to fight cancer

In their quest to destroy cancer cells, researchers are turning to combinational therapies more and more. Scientists from Germany and China have now combined a chemotherapeutic and photodynamic approach.

Cell-free DNA blood tests may help predict pregnancy complications

UCLA researchers say a blood test commonly used to detect fetal genetic abnormalities may help predict complications associated with pregnancy before symptoms develop.

New study details how Michigan nursing homes limited the spread of coronavirus

Seven months ago, the nation first heard of a surge of COVID-19 deaths in a Washington nursing home – an early warning sign of how the coronavirus could rip through such facilities.

SARS-CoV-2 antibodies and COVID symptoms can last at least 3 months

Recent research published as a preprint on the medRxiv preprint server, Elizabeth T. Cirulli et al., studies the self-reported short and long-term symptoms in a large general adult population cohort.

Dynamic map reveals how cells fight microbes and preserve memory for future infections

Researchers have charted the activity of tens of thousands of genes in mouse immune cells over the course of an infection.

Study elucidates the role of ERβ in growth of skeletal muscle in female mice

Researchers at Kumamoto University, Japan generated mice lacking the estrogen receptor beta (ERβ) gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal muscle in female mice.

Study shows how mutations in VAV1 gene may promote T-cell tumors in experimental mice

Life is an exquisite orchestration of growth and change, with checks and balances that fine-tune complex entwined interactions, both intrinsic and external.

Scientists discern molecular mechanisms underlying plant parasitism, cross-species grafting

Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena.
