Chemists unravel how bicarbonate can protect cells from oxidative stress in a study that challenges how cell damage has been studied for decades.
Simple lab-free test to detect bacteria in fluids from water to urine
Engineers and biochemists have brought their skills together to make it possible for untrained users to confirm contamination in fluids using a biogel test that changes color in the presence of such bacteria as E. coli, listeria and other frequent testing targets.
Improved catalyst turns harmful greenhouse gases into cleaner fuels, chemical feedstocks
A chemical reaction can convert two polluting greenhouse gases into valuable building blocks for cleaner fuels and feedstocks, but the high temperature required for the reaction also deactivates the catalyst. A team has found a way to thwart deactivation. The strategy may apply broadly to other catalysts.
Cellular ‘power plants’ control inflammation
Researchers discover how mitochondria not only produce energy but also influence inflammation.
Fighting aging by staying compact
The secret to cellular youth may depend on keeping the nucleolus -- a condensed structure inside the nucleus of a cell -- small, according to nvestigators. The findings were elucidated in yeast, a model organism famous for making bread and beer and yet surprisingly similar to humans on the cellular...
How climate change threatens this iconic Florida bird
A new analysis of data from a long-term study finds that warmer winters driven by climate change reduced the number of offspring raised annually by the federally threatened Florida scrub-jay by 25% since 1981.
‘Biodiversity is not a luxury’: Connection between wealth and ecosystem health
This study examines the positive correlation between an area's wealth and biodiversity, known as the 'luxury effect.' The authors present an alternative framework for understanding links between socio-economic factors and ecosystem health which emphasizes the agency of less-wealthy communities in promoting healthy ecosystems where they live.
Prehistoric hunter-gatherers heard the elks painted on rocks ‘talking’
Researchers performed acoustic impulse response measurements in front of 37 rock painting site and found that the same vertical rock surfaces that have the painted elks, humans and boats, are also effective sound reflectors.
Focaccia: A Neolithic culinary tradition dating back 9,000 years ago
A new study indicates that during the Late Neolithic, between 7000 and 5000 BCE, the fully agricultural communities in the Fertile Crescent region of the Near East, developed a complex culinary tradition that included the baking of large loaves of bread and 'focaccias' with different flavors on special trays known...
Bats’ amazing plan B for when they can’t hear
When bats can't hear, new research finds that these hearing-dependent animals employ a remarkable compensation strategy.
