A team of Carnegie Mellon researchers found that Pittsburgh’s air pollution levels decreased during the stay-at-home order—but the overall impact remains small.

Concentrations of sulphur dioxide in polluted areas in India have decreased by around 40% between April 2019 and April 2020.

New research has identified the specific brain cells that control how much sugar you eat and how much you crave sweet tasting food

Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. A research group from the University of Basel and the University Hospital Basel has now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.

In February 2020, a Covid-19 patient cohort was established at the University and the University Hospital in Basel to prospectively monitor a range of diagnostic means and potential treatments for Covid-19, including the off-label use of hydroxychloroquine and lopinavir/ritonavir.

A research group monitored lopinavir plasma levels in Covid-19 patients. “Considering that substantial inflammation was observed in these patients, and previous studies have shown the inhibition of drug metabolism by systemic inflammation, we had the rationale to investigate the effect of inflammation on lopinavir and hydroxychloroquine plasma levels,” states Professor Catia Marzolini, first author of the study and professor for experimental medicine at the University of Basel.

Move over, murder hornets. There’s a new bee killer in town.

Aquaculture, the relatively young but fast-growing industry of farming of fish and other marine life, now produces around half of all seafood consumed by humans.

While ocean acidification was initially perceived as a threat only to the marine realm, the authors of a new publication argue that it is also an emerging human health issue.

Living close to natural green space can mitigate some of the changes in infant gut bacteria associated with formula feeding, according to new research published in the journal Environment International.

Microparticles offer a promising way to deliver multiple doses of a drug or vaccine at once, because they can be designed to release their payload at specific intervals.

Researchers at Karolinska Institutet have developed a new method that can make it easier for public authorities to assess the health risks of hormone-disrupting chemicals in the environment.
