Scientists map how cinnamon’s bioactives interact with cancer signaling

This review synthesizes preclinical evidence showing that cinnamon-derived compounds can modulate inflammation, oxidative stress, apoptosis, and angiogenesis through multiple cancer-related signaling pathways. While biologically plausible, the findings are largely limited to cell and animal models, underscoring the need for pharmacokinetic, safety, and clinical validation.

Indoor tanning loads normal skin with mutations linked to melanoma

Indoor tanning is associated with markedly higher mutation burdens and cancer-driving genetic changes in melanocytes taken from normal-appearing skin, including areas usually protected from sunlight. These molecular alterations provide a biological explanation for the higher odds of melanoma and multiple primary tumors seen in heavy tanning bed users.

Circadian control of neutrophils limits heart damage after myocardial infarction

Neutrophils cause time-of-day–dependent collateral tissue damage after sterile injury through an intrinsic circadian program. Activating a CXCL12–CXCR4 checkpoint repositions neutrophils, limiting inflammatory injury without impairing antimicrobial defense.

GDF3 protein sustains harmful inflammation in aging immune cells

As people age, their bodies develop a dysfunctional immune system, which can leave older adults more susceptible to conditions like sepsis.

Chemotherapy may reduce HIV-infected T cells

Advancements in HIV/AIDS research, drug development and clinical practice since the 1980s have made it possible for people living with HIV to lead long, productive lives and keep the virus in check at undetectable levels and nontransmissible as long as therapy is maintained.

Smartwatch alerts help parents manage children's tantrums

Mayo Clinic researchers have developed a smartwatch-based alert system that signals parents at the earliest signs of a tantrum in children with emotional and behavioral disorders - prompting them to intervene before it intensifies.

Air pollution and immune changes could trigger autoimmune conditions

A new study has linked air pollution exposure and immune-system changes that often precede the onset of autoimmune diseases.

New framework tracks response to anti-amyloid therapies in Alzheimer's

In the last few years, progress has been made in the fight against Alzheimer's disease with a class of therapies called anti-amyloid antibodies (anti-Aβ).

Blood test identifies colon cancer patients who benefit from anti-inflammatory medication

A blood test could help doctors decide which patients with colon cancer should receive anti-inflammatory medication along with chemotherapy after surgery, according to new study in JAMA Oncology.

Lipoic acid shows limited benefit in progressive multiple sclerosis

The over-the-counter supplement lipoic acid may have a small beneficial effect in slowing the loss of gray matter in the brains of people with progressive forms of multiple sclerosis, according to new research led by Oregon Health & Science University and the Portland VA Health Care System.

New insights explain the Treg paradox in colorectal cancer

In most solid tumors, high numbers of regulatory T (Treg) cells are associated with poorer outcomes because they dampen the immune system's ability to fight against a tumor.

New insights into alcohol-related DNA damage and cancer risk

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA.

Scientists create light-controlled versions of cholesterol

High levels of cholesterol are linked to heart disease, stroke, and many other health problems. However, this complex and vital fatty, water insoluble molecule-a lipid-is found in every cell of the body and is not all bad news. It also regulates crucial processes that science has yet to map.

Inclusive swimming lessons boost safety and confidence for Black youth

Black youth in the United States disproportionately experience fatal drowning at rates up to five times higher than their White peers.

Novel diagnostic approach enables detection of antibiotic resistance and pathogenicity in Klebsiella strains

Antibiotic resistance is one of the most pressing—and quietly advancing—challenges facing modern medicine. Among the most dangerous bacterial pathogens driving this crisis is Klebsiella pneumoniae, a microorganism capable of causing severe infections while evading both antibiotics and the human immune system.

How brain cells manage long distance genetic instructions

Scientists found that messenger RNA (mRNA) molecules that carry genetic instructions to the far reaches of neurons in the brain tend to cluster together mostly because they are abundant, not because they move in coordinated groups.

Novel AI tool not only identifies genetic mutations but also predicts the type of disease

Scientists at the Icahn School of Medicine at Mount Sinai have developed a novel artificial intelligence tool that not only identifies disease-causing genetic mutations but also predicts the type of disease those mutations may trigger.
