Nature documentaries increasingly talk about threats to nature, but still don't show them

Researchers analyzing recent BBC and Netflix nature documentaries found that although they increasingly mention threats to nature, visual depictions of these threats remain scarce, potentially misleading audiences on the state of the natural world.

Palmer amaranth's molecular secrets reveal troubling potential

Corn, soybean, and cotton farmers shudder at the thought of Palmer amaranth invading their fields. The aggressive cousin of waterhemp – itself a formidable adversary – grows extremely rapidly, produces hundreds of thousands of seeds per plant, and is resistant to multiple classes of herbicides. New research explains Palmer's evil genius.

Climate change expected to accelerate spread of sometimes-fatal fungal infection

Valley fever is endemic to hot and dry regions like the southwestern United States and California's San Joaquin Valley, but a new study predicts climate change will cause the fungal infection's range to more than double in size this century, reaching previously unaffected areas across the western U.S.

We need more realistic experiments on the impact of climate change on ecosystems

When it comes to the impact of climate change on ecosystems, we still have large knowledge gaps. Most experiments are unrealistic because they do not correspond to projected climate scenarios for a specific region. Thus, we lack reliable data on what ecosystems might look like in the future, as a team of biodiversity researchers show.

Antibiotic resistance surges in dolphins, mirroring humans


Scientists obtained a total of 733 pathogen isolates from 171 individual wild Bottlenose dolphins in Florida and found that the overall prevalence of resistance to at least one antibiotic for the 733 isolates was 88.2%. Resistance was highest to erythromycin, followed by ampicillin. It is likely that these isolates from dolphins originated from a source where antibiotics are regularly used, potentially entering the marine environment through human activities or discharges from terrestrial sources.
