Fluctuations in weight, blood pressure, cholesterol and/or blood sugar levels in otherwise healthy people may be associated with a higher risk of heart attack, stroke and death from any cause compared to people with more stable readings, according to new research in the American Heart Association’s journal Circulation.

Many Americans visit chiropractors to address pain, often without informing their physicians.

Melbourne scientists have revealed a better way to identify which patients should respond to powerful ovarian cancer drugs called PARP inhibitors (PARPi), resolving an important question in ovarian cancer care about why some patients respond to the drugs, while others do not.

People can die simply because they’ve given up, life has beaten them and they feel defeat is inescapable, according to new research.

Rutgers researchers have developed a tool to help neurologists screen for obstructive sleep apnea in people with epilepsy whose seizures can be magnified by sleep disorders.

Since December 2016, Brazil has been grappling with its worst yellow fever outbreak for several decades. To date, there have been 2,043 human cases including 676 fatalities, mainly occurring in ten Brazilian states including Rio de Janeiro and São Paulo. These two states, the most heavily populated in Brazil, had been free of yellow fever for nearly 70 years. Research by scientists at the Institut Pasteur and the Institut Oswaldo Cruz has demonstrated that the yellow fever virus can be transmitted via Aedes albopictus, the tiger mosquito. This opportunistic species is capable of colonizing both urban and forest areas.

A University of Adelaide-led team of researchers has found a link between sudden cardiac death (when the heart suddenly stops beating) and a common heart condition known as mitral valve prolapse that affects around 12 in every 1000 people worldwide.

The Sherpa people of the Himalayas have long been recognized for their unique ability to excel physically in the thin air of higher altitudes. But new research from UBC’s Okanagan campus, published last week in the Journal of Physiology, now suggests that their specially adapted muscles give them up to twice the resistance to muscle fatigue of lowlanders.

An innovation in liquid metal chemistry could help one tenth of the planet’s population get access to clean drinking water at very low cost following breakthrough research.

Outdoor air pollution is a major contributor to indoor air pollution -- but high-efficiency particulate air (HEPA) filters used in the home significantly reduce fine-particulate matter in the air compared with non-HEPA air filters.
