Cellular death is a fundamental concept in the biological sciences. Given its significance though, its definition depends on the context in which it takes place, and lacks a general mathematical definition. Researchers propose a new mathematical definition of death based on whether a potentially dead cell can return to a...
Cellular traffic congestion in chronic diseases suggests new therapeutic targets
Chronic diseases such as diabetes are on the rise and are costly and challenging to treat. Scientists have discovered a common denominator driving these diverse diseases, which may prove to be a promising therapeutic target: proteolethargy, or reduced protein mobility, in the presence of oxidative stress.
‘Genetic time machine’ reveals complex chimpanzee cultures
Chimpanzees are known for their remarkable intelligence and use of tools, but could their cultures also evolve over time like human cultures? A new, multidisciplinary study suggests that some of their most advanced behaviors may have been passed down and refined through generations.
It might be wrecking the climate, but carbon dioxide is actually good for your cells
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.
UAF Enhances Seaglider Technology to Measure Carbon Dioxide
Scientists around the world rely on ocean monitoring tools to measure the effects of climate change.
King Salmon Declines Linked to Climate, Smaller Size
King salmon have sustained people in Alaska for at least 12,000 years, but over the past three decades their populations have begun to dwindle.
Unexplained Heat-Wave ‘Hotspots’ Are Popping Up Across the Globe
Earth’s hottest recorded year was 2023, at 2.12 degrees F above the 20th-century average. This surpassed the previous record set in 2016.
