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 use tiny glass capillaries to sample living cancer cell parts

A new analytical method could improve how cancer treatments are designed - by allowing scientists to track, for the first time, exactly where inside a living cell a drug accumulates. Researchers from the University of Surrey and King's College London developed the method, which detects trace amounts of metal inside individual living cells and their internal compartments without the need to kill the cells first

Study explains the link between NDMA-contaminated water and childhood cancer

A new study from MIT suggests that a carcinogen that has been found in medications and in drinking water contaminated by chemical plants may have a much more severe impact on children than adults.

Why AI is becoming a powerful tool in cancer drug discovery

This Perspective reviews how AI is moving drug discovery from long, costly experimental pipelines toward earlier clinical translation, with an AI-designed TNIK inhibitor trial serving as an important proof-of-feasibility reference point. It argues that precision oncology could benefit from AI-driven integration of multi-omics, federated learning, and adaptive trial design, but only if validation, fairness, interpretability, and regulatory alignment improve.

How the immune system may influence Alzheimer’s, Parkinson’s, and related diseases

This review argues that neurodegeneration is shaped not only by toxic protein buildup but also by immune signaling, with microglia and T cells able to either protect the brain or worsen damage depending on context. It also highlights aging, head injury, and viral infection as major forces that reshape CNS immunity and may influence disease progression and future treatment strategies.

Scientists discover a biological "memory" of breastfeeding in child blood samples

Babies who are exclusively breastfed for at least three months carry markers in their blood that differ from babies who are not breastfed.

Scientists find "hidden" pre-cancer signs in advanced esophageal cancer patients

Scientists have found the strongest evidence to date that a condition known as Barrett's esophagus is the starting point for all cases of esophageal adenocarcinoma – the most common type of esophageal cancer in the developed world – even when telltale signs of this pre-cancerous stage are no longer visible.

New research reveals how bacteria "selflessly" share DNA through GTAs

Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR).

Epigenetic changes allow cancer cells to shift identity and survive drugs

Cancer drugs are designed to shut tumors down. But sometimes, in the very act of attacking a tumor, treatment can also help a small fraction of cancer cells become harder to kill. A new study from researchers at the Institute for Systems Biology (ISB) shows that cancer cells may begin escaping therapy much earlier - as the therapy itself triggers a stress response that drives some cancer cells into a temporary drug-tolerant state.

New lab-grown organoids accurately mimic pediatric brain tumor biology

Efforts to identify and evaluate next-generation therapeutics for pediatric brain tumors are easily stymied by the quality and availability of laboratory models for research. To address this issue, scientists at St. Jude Children's Research Hospital developed patient-derived tumor organoids and tumor organoid xenografts that accurately reflect the biologic underpinnings of embryonal brain tumors.

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.

New RNA sequencing method improves rare disease diagnosis

Researchers from Children's Hospital of Philadelphia (CHOP) developed a new RNA sequencing strategy that can reveal how genetic variants disrupt gene function and improve the diagnosis of rare diseases.

Mitochondrial activity keeps dendritic cells ready to fight disease

Researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) show that active mitochondria maintain dendritic cells, the immune system's sentinels, in a "ready-to-respond" state, linking cellular metabolism to gene regulation and T-cell activation.

Aston University bioscientist receives £125,000 to investigate genetic reasons for neurodegeneration

Aston University bioscientist Dr John Reynolds has won a £125,000 Springboard grant from the Academy of Medical Sciences (AMS) for research into neurodegeneration caused by a rare genetic disease.

New grant funds AI search for genetic targets to treat Alzheimer's

With a new $6.2 million, five-year grant from the National Institute on Aging, researchers at Case Western Reserve University will use artificial intelligence (AI) and machine learning to identify possible genetic targets to treat Alzheimer's disease.

New CRISPR tool selectively cuts tumor DNA while sparing healthy cells

Cancer cells excel at evading detection, but subtle chemical differences set them apart from healthy cells.

Dutch study shows off-label targeted therapies benefit more cancer patients

The largest published prospective evaluation of off-label targeted cancer therapies has shown that more patients could benefit from existing drugs.

AP-1 proteins help cancer cells rewire genes to survive treatment

A long-standing mystery in cancer treatment is how tumor cells so often become resistant to drugs, even ones they have never encountered before.

Brain organoids reveal mutation-specific insights for Rett syndrome

Though many studies approach the developmental disorder Rett syndrome as a single condition arising from general loss of function in the gene MECP2, a new study by neuroscientists in The Picower Institute for Learning and Memory at MIT shows that two different mutations of the gene caused many distinct abnormalities in lab cultures.
