The risks of exposure to “forever chemicals” start even before birth, a new study confirms, potentially setting up children for future health issues.

Exposure to per- and polyfluoroalkyl substances (PFAS) during pregnancy was linked to slightly higher body mass indices and an increased risk of obesity in children, according to a new Environmental Health Perspectives study led by Brown University researchers.

While this link has been suggested in previous research, the data has been inconclusive. The new study involves a much broader data set with research sites across the country, said lead author Yun “Jamie” Liu, a postdoctoral research associate in epidemiology at the Brown University School of Public Health.

“The findings were based on eight research cohorts located in dif...

Fatigue is the symptom that most significantly impacts the daily lives of long COVID patients, and can affect quality of life more than some cancers, finds a new study led by researchers at UCL and the University of Exeter.

The research, published in BMJ Open , examines the impact of long COVID on the lives of over 3,750 patients who were referred to a long COVID clinic and used a digital app as part of their NHS treatment for the condition.

Patients were asked to complete questionnaires on the app about how long COVID was affecting them—considering the impact of long COVID on their day-to-day activities, levels of fatigue, depression, anxiety, breathlessness, brain fog, and their quality of life.

The researchers found that many long COVID p...

NASA’s Parker Solar Probe (PSP) has flown close enough to the sun to detect the fine structure of the solar wind close to where it is generated at the sun’s surface, revealing details that are lost as the wind exits the corona as a uniform blast of charged particles.

It’s like seeing jets of water emanating from a showerhead through the blast of water hitting you in the face.

In a paper to be published in the journal Nature, a team of scientists led by Stuart D...
