Researchers have known since at least 2008 that wildfires can create chromium-6, but a new study, published in the journal Environmental Science and Technology in November, is the first to report details such as how long it might persist in groundwater.
Research shows that summertime conditions can lead to cognitive impairments, particularly in memory and concentration. Factors such as sleep disruption, heat, dehydration, and smoke exposure are significant contributors to these effects.
During this heat wave, "not only are daily temperature records likely to be broken across the region, but even the high temperature records for any day in the entire month of March," the National Weather Service said in a Tuesday morning forecast.
There's a glorious smugness that can only be experienced by exercising outdoors in winter conditions. The fresh air, the endorphins, the reduced risk of heart disease they're all nice bonuses, but nothing beats that knowing nod from another rain-drenched runner, or the horrified faces of nearby dog walkers as you stride confidently into the sea for a winter dip.
A total 5,722 people died as a direct result of the summer heat in 2025, the third hottest summer on record and one which featured two severe extended heatwaves in late June/early July and in the middle of August, a Santé Publique France report shows. Of those fatalities, more than 1,900 were attributed directly to heat exposure - which represented 12 percent of all deaths during the periods of high heat.
"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."
Because the past three years have shattered temperature records, researchers have been exploring whether global warming is accelerating, and if so, why. Many scientists agree that the rate at which it is increasing has picked up. This is mainly because of a reduction in air pollution following the introduction of fuel regulations for international shipping (which has resulted in fewer pollutant particles that reflect sunlight into space and seed insulating clouds).
Being overweight doesn't just make people more susceptible to chronic illnesses such as heart disease and diabetesit might also increase their risk of severe influenza and other infections, a new study confirms. The study, published today in the Lancet, suggests that people with obesity may be more susceptible to death and hospitalization from a variety of infections caused by viruses, fungi, parasites and bacteria.
