Researchers studied human colon cancer tissue samples and animal models and found that exposure to salmonella was linked with colon cancers that developed earlier and grew larger.
Climate change likely to uproot more Amazon trees
Tropical forests are crucial for sucking up carbon dioxide from the atmosphere. But they're also subject to intense storms that can cause 'windthrow' -- the uprooting or breaking of trees. A new study finds that more extreme thunderstorms from climate change will likely cause a greater number of large windthrow...
Probiotic markedly reduces S. Aureus colonization in phase 2 trial
A promising approach to control Staphylococcus aureus bacterial colonization in people -- using a probiotic instead of antibiotics -- was safe and highly effective in a Phase 2 clinical trial. The new study found that the probiotic Bacillus subtilis markedly reduced S. aureus colonization in trial participants without harming the...
Unusual compound found in Rembrandt’s The Night Watch
Scientists have discovered a rare lead compound (named lead formate) in Rembrandt's masterpiece The Night Watch. This rare discovery provides new insight into 17th-century painting technique and the conservation history of the painting.
Bees exposed to common weedkiller via wildflower nectar
Bees may be at risk from exposure to glyphosate -- an active ingredient in some of the EU's most commonly used weedkillers -- via contaminated wildflower nectar, according to new research. Residues of glyphosate have previously been found in nectar and pollen collected by bees foraging on plants that have...
Glassy and reactive: Plants are more dynamic than you think
Is the inside of a plant cell more like a liquid or a solid? While this may sound like an odd question, new research demonstrates it can be either, depending on how much light you shine on it. Chloroplasts within plant cells constitute an active form of matter that undergoes...
Marriage in Minoan Crete
An international team of researchers achieves completely new insights into Bronze Age marriage rules and family structures in Greece. Analyses of ancient genomes show that the choice of marriage partners was determined by one's own kinship.
Climate conundrum: Study finds ants aren’t altering behavior in rising temperatures
A new study finds that ants are not adjusting their behavior in response to warming temperatures, persisting in sub-optimal microhabitats even when optimal ones were present. The finding suggests ants may not be able to adjust their behavior in response to warming ecosystems.
Genetically modified rice could be key to tackling food shortages caused by climate change
Reducing the number of stomata that rice have makes them more tolerant to salt water, according to researchers.
20,000 premature US deaths caused by human-ignited fires each year
A new study shows that smoke particles from human-lit fires are responsible for over 80% of smoke-related deaths each year. The study shows that smoke pollution is on the rise, reducing air quality, and leading to increased illness and premature deaths.
