Non-genetic theories of cancer address inconsistencies in current paradigm
It’s time for researchers to reconsider the current paradigm of cancer as a genetic disease, argued Sui Huang from the Institute for Systems Biology, USA, and colleagues in a new essay published March 18 in the open-access journal PLOS Biology.
The prevailing theory on the origin of cancer is that an otherwise normal cell accumulates genetic mutations that allow it to grow and reproduce unchecked. This paradigm has driven large-scale cancer genome sequencing projects, such as The Cancer…

Blood pressure patterns during pregnancy predict later hypertension risk, study finds
Women with blood pressure levels in a range considered clinically normal during pregnancy but no mid-pregnancy drop in blood pressure face an increased risk of developing hypertension in the five years after giving birth. These women — about 12% of the population studied — would not be flagged as high-risk by current medical guidelines, but the new findings could help identify them as candidates for early intervention. The findings were just published in the Journal of the American College…

Latest Alzheimer’s drug shown less effective in females than males
Since becoming only the second Alzheimer’s-modifying drug to gain American Federal Drug Administration approval in 2023, sales of lecanemab, known by its brand name Leqembi, have risen steadily, reaching $87-million USD in the last quarter of 2024.
In its Phase 3 clinical trial, lecanemab slowed cognitive decline by 27 per cent overall, yet one subset of data suggested little to no benefit in females, though the cause of the difference was not clear. An FDA committee voted unanimously that…

Vaccine may improve breast cancer treatment outcomes
Moffitt Cancer Center researchers have discovered a promising new vaccine strategy for treating a specific type of breast cancer. The innovative approach targets human epidermal growth factor receptor 2-positive, estrogen receptor-negative (HER2-positive, ER-negative) breast cancer and has shown encouraging results in a recent pilot study. Published in npj Breast Cancer, the study combined the HER2-targeting dendritic cell vaccines with standard chemotherapy, demonstrating both safety and…

Whose air quality are we monitoring?
U.S. Environmental Protection Agency (EPA) air quality monitors are disproportionally located in predominately white neighborhoods, according to University of Utah research. The EPA’s network consistently failed to capture air quality in communities of color across six major pollutants, particularly lead and sulfur dioxide, followed by ozone and carbon monoxide.
EPA regulatory monitors are the key data source driving decisions about pollution reduction, urban planning and public health…

Researchers find missing link in autoimmune disorder
Autoimmune diseases, which are estimated to affect more than 15 million people in the U.S., occur when the body responds to immune-system false alarms, and infection-fighting first responders are sent out to attack threats that aren’t there. Scientists have long understood how the false alarms get triggered, but the second step of dispatching the immune response has been a mystery.
Now, scientists at Washington University School of Medicine in St. Louis and the Perelman School of Medicine at…

Cannabis users face substantially higher risk of heart attack
Marijuana is now legal in many places, but is it safe? Two new studies add to mounting evidence that people who use cannabis are more likely to suffer a heart attack than people who do not use the drug, even among younger and otherwise healthy adults. The findings are from a retrospective study of over 4.6 million people published in JACC Advances and a meta-analysis of 12 previously published studies being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).

Lifestyle risks weigh heavier on women’s hearts
Lifestyle and health factors that are linked with heart disease appear to have a greater impact on cardiovascular risk in women than men, according to a study being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).
While factors such as diet, exercise, smoking and blood pressure have long been linked with heart disease risk, the new study is the first to show that these associations are collectively stronger in women than men. According to the researchers,…

AI food scanner turns phone photos into nutritional analysis
Snap a photo of your meal, and artificial intelligence instantly tells you its calorie count, fat content, and nutritional value — no more food diaries or guesswork.
This futuristic scenario is now much closer to reality, thanks to an AI system developed by NYU Tandon School of Engineering researchers that promises a new tool for the millions of people who want to manage their weight, diabetes and other diet-related health conditions.
The technology, detailed in a paper presented at the 6th…
