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.

Study identifies education as a key predictor of hip surgery recovery

Level of education is the socio-economic factor most strongly associated with survival rates after acute hip surgery. This is shown in a Linköping University study of 58,000 people.

Biodegradable 'nanobone' material helps body regrow jawbone

For children born with cleft lip and palate, repairing gaps in the jawbone often means waiting until they are 10 to 12 years old before undergoing invasive bone graft surgery.

Study links popular weight-loss drugs to increased male hair loss

Men already at risk genetically for the most common form of hair loss have a 7 percent added risk of losing their hair if they use drugs like Ozempic, Wegovy, and Zepbound for type 2 diabetes and obesity, a new study shows.

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.

Cancer drug eliminates HIV-infected cells in animal model study

Emory University researchers have provided the first proof-of-concept in a nonhuman primate model for eliminating HIV-infected cells with venetoclax, a clinically approved medication for cancer.

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.

Neural networks reveal how training shapes learning in living brains

A new study has used a type of machine learning called a neural network to reveal how different kinds of training can change how learning happens-both in machines, and in living brains.

Targeting KV7 proteins could help delay preterm labor

Scientists have found that targeting a particular group of proteins in the uterus muscle (myometrium) can suppress human uterine contractions in laboratory studies and delay preterm birth in a preclinical model.

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.

Maternal illness may reshape fetal brain development through epigenetics

Neurodevelopmental conditions, which include autism spectrum disorders, ADHD (attention-deficit/hyperactivity disorder), and more, impact around ten percent of the American population.

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.

Bright light therapy boosts activity and sleep in older adults

Bright light therapy lamps can improve sleep, activity levels and circadian rhythms of older adults in urban areas who have diminished exposure to natural light, a new study from the University of Surrey reports.

Progesterone levels linked to brain patterns underlying mood changes

The influence of the hormone progesterone on mood is well known. Now researchers from the University of Barcelona have shown how higher levels of progesterone during the menstrual cycle are linked to less distinct patterns of activity in areas of the brain involved in controlling emotions.
