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).

CRISPR/Cas9 gene editing can cause greater genetic damage than previously thought

Scientists at the Wellcome Sanger Institute have discovered that CRISPR/Cas9 gene editing can cause greater genetic damage in cells than was previously thought. These results create safety implications for gene therapies using CRISPR/Cas9 in the future as the unexpected damage could lead to dangerous changes in some cells.

Researchers solve mystery of final blood group system

Ever since the blood type was discovered in 1962, no one has been able to explain why some people become Xga positive while others are Xga negative.

Improved methods to measure enterococci concentrations in recreational water

The concentration of enterococci, bacteria that thrive in feces, has long been the federal standard for determining water quality.

A Multi-Modal Approach for the Early Detection of Breast Cancer

Professor Samir Iqbal describes his research in the field of breast cancer detection and how machine learning can improve early diagnosis rates.

Purdue startup to create sensor that provides early detection of mosquito-borne diseases

A startup created by Purdue University professors is developing a sensor that can detect dangerous mosquito-borne tropical diseases faster and at a lower cost than current methods, giving health officials time to take action before the viruses are transmitted to humans.

Researchers reveal massive genome havoc in breast cancer

In cancer cells, genetic errors wreak havoc. Misspelled genes, as well as structural variations -- larger-scale rearrangements of DNA that can encompass large chunks of chromosomes -- disturb carefully balanced mechanisms that have evolved to regulate cell growth.

Scientists identify structural and functional differences in human immune-surveillance protein

The human body is built for survival. Each one of its cells is closely guarded by a set of immune proteins armed with nearly foolproof radars that detect foreign or damaged DNA.

Calcium electrotransfer could be used to target cancer cells, study finds

Several different treatment methods are used against cancer and multiple promising approaches are currently under examination by various institutions around the world.

Researchers develop novel approach to bridge gap in cell-free systems

Engineering cellular biology, minus the actual cell, is a growing area of interest in biotechnology and synthetic biology.

New technique measures how well cancer drugs reach their targets

Scientists have developed a technique that allows them to measure how well cancer drugs reach their targets inside the body.

Study uncovers possible link between iron loading, alcohol intake and mortality

Drinking heavily results in uncontrolled iron absorption into the body, putting strain on vital organs and increasing the risk of death, according to a new study published in the journal Clinical Nutrition.

Scientists support viability of potential way to reduce Alzheimer's disease risk

A new commentary by scientists at the Universities of Manchester and Edinburgh on a study by Taiwanese epidemiologists supports the viability of a potential way to reduce the risk of Alzheimer's disease.

UZH scientists identify enzyme that controls cell division

When a cell divides, its constituents are usually evenly distributed among the daughter cells. UZH researchers have now identified an enzyme that guarantees that cell constituents that are concentrated in organelles without a membrane are properly distributed.

Blood telomeres can help predict risk of disease worsening or death in COPD patients

Some patients with COPD demonstrate signs of accelerated aging. In a new study published in the journal CHEST researchers report that measuring blood telomeres, a marker of aging of cells, can be used to predict future risk of the disease worsening or death.

New study identifies inherited genetic variants that raise risk of clonal hematopoiesis

A new study led by researchers at Harvard Medical School and the Harvard T.H. Chan School of Public Health has identified some of the first known inherited genetic variants that significantly raise a person's likelihood of developing clonal hematopoiesis, an age-related white blood cell condition linked with higher risk of certain blood cancers and cardiovascular disease.

Attempts to reunite separated families should not misuse medical tests, says ACP

In a new policy issued today, the American College of Physicians (ACP) stated that immigrant families who have been separated at the border should be reunited as expeditiously as possible.

New findings refine link between clonal hematopoiesis and blood cancer risk

It's a common occurrence in elderly people: Blood cells carrying mutated DNA explosively increase in number, resulting in genetic "mosaicism": the presence of a population of cells that carries an altered genome.

Study suggests database analysis better predicts toxicity of chemicals than animal testing

Advanced algorithms working from large chemical databases can predict a new chemical's toxicity better than standard animal tests, suggests a study led by scientists at Johns Hopkins Bloomberg School of Public Health.

Growing pains in CRISPR gene editing

In the six years since its inception, CRISPR gene editing has experienced ups and downs, from giddy excitement over the technology's potential to cure genetic diseases to patent disputes, ethical considerations and cancer scares.

Novel informatics tool helps predict genomic features associated with specific drug responses

The rise of genomics, the shift from considering genes singly to collectively, is adding a new dimension to medical care; biomedical researchers hope to use the information contained in human genomes to make better predictions about individual health, including responses to therapeutic drugs.
