Research news on Environmental Biomarkers

Environmental biomarkers, as a biological process, encompass the organismal and cellular responses by which living systems detect, transduce, and manifest measurable changes to environmental exposures such as pollutants, radiation, or other stressors. This process involves molecular events including altered gene expression, protein modification, metabolite shifts, and physiological or behavioral changes that collectively encode information about exposure, effect, or susceptibility. These responses generate quantifiable indicators (e.g., specific stress proteins, oxidative damage products, enzyme activities) that integrate dose, duration, and biological impact of environmental factors, thereby serving as mechanistic links between external stressors and ensuing adaptive, toxic, or pathogenic outcomes in organisms and ecosystems.

Even small amounts of ocean plastic can affect petrel chicks

Ocean plastic pollution is accidentally on the menu for southern giant petrel chicks. Even small nibbles of it may affect their physiology during development, according to a study from the University of California, Davis, ...

Honey bees can serve as sentinels for environmental health

Honey bees (Apis mellifera) are widely known as essential pollinators, but researchers using a "One Health" approach have also identified them as biological sentinels of environmental health. Honey bees continuously interact ...

Seawater samples may offer early clues to changing reef health

Doctors can often detect diseases in humans using minimally invasive methods, like blood or urine tests, before symptoms become severe. Now, researchers at the Woods Hole Oceanographic Institution (WHOI) are applying a similar ...

Are we missing the universe's 'noosignatures?'

Astrobiology has long been split into two camps: a search for "biosignatures" and a search for "intelligence." These look for very different things, but they also leave a huge gap in between. It took 3.5 billion years for ...
