Cancer-fighting T cells need small amounts of ROS to attack tumors, study finds

New research reveals a promising new target for treating cancer by harnessing a type of molecule previously thought to do more harm than good.

Microscopic peptide droplets reduce colorectal tumor growth in mice

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth of hard-to-treat colorectal tumours by about 67 per cent in mice.

Increasing Canadian wildfires jeopardize critical care for dialysis patients

In the midst of another intense wildfire season, a new study sheds light on the risks they pose to life-sustaining dialysis care for thousands of Canadians.

Cerebral palsy may be a trait rather than a disease

Historically, cerebral palsy (CP) was linked largely to events at birth, including prematurity or temporary loss of oxygen to the brain, but research over the past decade has suggested that genetic factors contribute to CP in many children.

IBD patients with family cancer history more likely to develop colorectal cancer

People with inflammatory bowel disease (IBD) who have several close relatives with colorectal cancer are significantly more likely to develop the disease themselves.

Brain-protecting immune cells may actually drive Alzheimer's disease

Immune cells that normally protect the body from damage by attacking foreign or infected cells are found in the brains of patients with Alzheimer's disease and related disorders at much higher levels than in healthy brains.

Too little or too much testosterone may matter for heart rhythm

A review of clinical trials, observational studies, genetic analyses, and mechanistic research suggests that atrial fibrillation risk may follow a U-shaped relationship with testosterone, increasing at both low and high levels. Evidence on testosterone replacement therapy remains mixed, with researchers calling for prospective studies to determine whether mid-physiological testosterone targets and treatment formulation influence AF risk.

Immigrants face longer ICU stays after stroke in Canada

Among people who have a stroke in Canada, immigrants were admitted to the intensive care unit (ICU) at similar rates as long-term residents or people who were born in Canada, but they were more likely to have longer stays in the ICU, according to a study published September 2, 2026, in Neurology, the medical journal of the American Academy of Neurology.

High-dose folic acid appears safe from formaldehyde toxicity

Folic acid – an essential vitamin added to flour and cereals and prescribed at high doses for cancer patients and people with blood disorders – does not elevate toxic formaldehyde in the body, according to a new Cornell University study on mice and human cancer patients who consumed high doses.

Daraxonrasib shows durable responses in RAS-mutant lung cancer

Daraxonrasib, an oral RAS inhibitor therapy, achieved durable responses in pretreated patients with RAS-mutant non-small cell lung cancer (NSCLC) in a Phase 1/2 trial led by The University of Texas MD Anderson Cancer Center.

Newly diagnosed AML patients benefit from less-intensive combination treatment

Investigators from the Mass General Brigham Cancer Institute have found that adults with newly diagnosed acute myeloid leukemia (AML) receiving a less-intensive combination of azacitidine and venetoclax had more than twice as much time before treatment failed, the leukemia returned or worsened, or they died, compared with patients receiving intensive chemotherapy.

Daily steps may match aerobic training for asthma control

For people with moderate to severe asthma, increasing the number of daily steps may be as effective as structured aerobic training sessions for managing the disease.

Shared biological pathways may explain chronic fatigue across diseases

A shared biological secret that helps explain chronic exhaustion in conditions including long Covid and PTSD has been discovered by researchers at the University of East Anglia and Oxford BioDynamics.

Alcohol-linked cancer deaths doubled over three decades in America

Alcohol-attributable cancer deaths in the U.S. doubled between 1990 and 2023, a new study found. The study also revealed that alcohol-linked cancer deaths are not limited to older adults or liver cancer.

Why addiction researchers are paying closer attention to GLP-1 drugs

A Journal of Clinical Investigation Viewpoint highlights growing evidence that GLP-1 receptor agonists, particularly semaglutide, may reduce alcohol consumption and some other substance-related outcomes by acting on brain systems involved in reward, motivation, stress, and emotion. However, the authors caution that efficacy for substance use disorders is not yet firmly established and call for further research into optimal dosing, treatment duration, patient selection, mechanisms, and effects across different addictions.
