Baseball food and drink: Healthy chemistry scores a surprise hit

Researchers found that sunflower seeds release a compound that may lower blood pressure, while moderate beer drinking reduces heart attack risk. Sauerkraut contains anti-cancer compounds, and onions help prevent bone loss. Meanwhile, regular hot dogs taste better than low-fat ones due to slower-releasing aroma compounds.

Retina adapts to seek the unexpected, ignore the commonplace

The retina's dynamic adaptation allows it to prioritize unusual features over routine ones, improving predictive coding and enhancing the ability to pick out new information. This process occurs rapidly, often within a few seconds of exposure to a novel environment, and is observed in both salamanders and mammals.

Did humans cause ecosystem collapse in ancient Australia?

Researchers found a sudden shift in plant type after humans arrived in Australia, leading to extinctions of large birds like Genyornis. The study used ancient wombat teeth and bird eggshells to analyze carbon isotopes, showing that human-induced vegetation change was the best explanation for the ecological transition.
