Everyone knows that exercise is good for you, but what type of training helps most, especially when you’re older - say over 65? A Mayo Clinic study says it’s high-intensity aerobic exercise, which can reverse some cellular aspects of aging. The findings appear in Cell Metabolism.

Mayo researchers compared high-intensity interval training, resistance training and combined training. All training types improved lean body mass and insulin sensitivity, but only high-intensity and combined training improved aerobic capacity and mitochondrial function for skeletal muscle. Decline in mitochondrial content and function are common in older adults.

The 2011 Fukushima catastrophe is an ongoing disaster whose end only gets more remote as time passes. The government is desperate to get evacuees back into their homes for the 2020 Tokyo Olympics, but the problems on the ground, and in the breached reactor vessels, are only getting more serious and costly, as unbelievable volumes of radiation contaminate land, air and ocean.

Temporary episodes of dizziness or light-headedness when standing could reduce blood flow to the brain with lasting impacts.

Defined as the loss of memory due to brain injury, shock, fatigue, repression or illness, amnesia can be short- or long-term, full or partial. Renowned expert in the cognitive neuroscience of memory, York Research Chair Shayna Rosenbaum, a professor of psychology in the Faculty of Health, has spent her professional life investigating, among other things, the mystery of amnesia.

Babies in prams accompanying older siblings on the school run are twice as likely to be exposed to harmful air pollution in the morning than in the afternoon, a new study has found.

Confidence in doctors, therapists and nursing staff leads to an improvement in subjectively perceived complaints, satisfaction and quality of life in patients. This is the conclusion of a meta-analysis by psychologists at the University of Basel, published in the journal PLOS ONE.

You are what you eat, as the saying goes, and while good dietary choices boost your own health, they also could improve the health care system and even benefit the planet. Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care.

As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.

Portland State University scientists have found that significant levels of cancer-causing benzene in e-cigarette vapors can form when the devices are operated at high power. 

The finding by a research team headed by chemistry professor James F. Pankow were published March 8 in the online journal PLOS ONE.   

A study published in the journal Health Communications shows that women at high risk for breast cancer who received a letter informing them of their options for additional imaging with contrast-enhanced MRI of the breast (in addition to a letter sent to their primary care physician) were more likely to return to the center for additional screening with MRI. The letter, which is included in the published paper, may help breast imaging centers navigate the complex legal, ethical and institutional landscapes in a way that increases the likelihood that women will follow through with American Cancer Society breast cancer screening recommendations for adjunct breast screening in women at elevated risk. 

The United States has managed to reduce the amount of air pollution it produces, but you wouldn’t know it from looking at and breathing in the air. That’s because pollution created in Asia is gradually making its way across the Pacific Ocean to the western hemisphere.

According to research published in the Atmospheric Chemistry and Physics journal, up to 65 percent of the newly created smog in the U.S. has actually drifted over from Asia. The country’s western states are most vulnerable to the increase in ozone due to their proximity to the continent.
