A new study suggests that a father’s COVID-19 infection could do more than make him sick – it may leave epigenetic marks on his sperm that pass anxiety to his offspring, revealing how viral infections can echo across generations.

People with severe chronic pain were far more likely to have elevated levels of eosinophils, a type of white blood cell, a new study found, hinting at an immune link to pain – but the rise in these cells didn’t make treatments any less effective.

What naked mole-rats lack in the looks department they make up for it in longevity, living healthily for nearly four decades. Now, scientists have found just how they repair their DNA – and it has the potential to be harnessed by humans to do the same.

When breathing becomes a daily battle, even the simplest acts can feel exhausting. Now, a new study has found the key to easing chronic breathlessness caused by lung disease: singing.

A new class of weight-loss drug has shown it can significantly boost weight loss when paired with GLP-1 therapy – without adding side effects – in a mid-stage clinical trial, pointing to a powerful new combination approach to tackling obesity.

A first-of-its-kind study has found that recognizing – and using – personal strengths is linked with better physical and psychological wellbeing and fewer mental-health challenges in adults with attention-deficit/hyperactivity disorder.

A large study has found that calcium supplements, long recommended for bone health, particularly in older women, don’t increase dementia risk, offering reassurance for the millions who take them to protect against osteoporosis.

Friendships, community ties and family bonds may apply the brakes to cell aging, providing a simple way to invest in health in older age. In a new study, scientists find that social connections are tied to slower biological aging and less inflammation.

Once confined to Latin America, Chagas disease – a potentially deadly parasitic infection that is spread in a gross way – is now endemic in the United States, threatening both humans and their pets in what experts are calling a silent public health crisis.

Knee and other joint-replacement procedures can be a major improvement to a patient's quality of life – unless infection sets in. A new method of injecting implants with liquid metal aims to take this harmful side effect out of the equation.

In a groundbreaking study, a healthy fatty acid in olive oil has been found to "supercharge" immune cells that fight cancer. Meanwhile, another kind of natural fat undermines the health of the same cells, killing them off and triggering inflammation.

A high-fat, low-carb ketogenic diet may protect the brain from early Alzheimer’s disease changes in people genetically at risk, new research suggests, by rebalancing gut bacteria and restoring brain energy metabolism.

A next-generation cancer vaccine has shown stunning results in mice, preventing up to 88% of aggressive and difficult-to-treat cancers by harnessing dual-pathway nanoparticles that train the immune system to recognize and destroy tumor cells.

Compounds in green tea can reprogram muscle metabolism to boost insulin sensitivity and glucose tolerance, according to new findings that further our understanding of why this ancient drink has long been linked to protect against obesity.

A review of existing research has found that tramadol’s pain relief benefits are minimal and may be outweighed by serious side effects, challenging the drug’s reputation as a “safer” opioid option for treating chronic pain.
