Phys.org / Vast freshwater reserves found beneath salinity-stressed coastal Bangladesh

Despite its tropical climate and floodplain location, Bangladesh—one of the world's most densely populated nations—seasonally does not have enough freshwater, especially in coastal areas. Shallow groundwater is often ...

Phys.org / PFAS concentrations can double with every step up the food chain

A new UNSW-led global meta-analysis shows that PFAS concentrations can double at every step up the food chain, leaving top predators—and humans—potentially exposed to higher chemical loads.

Phys.org / Nanoplastics have diet-dependent impacts on digestive system health, study finds

Plastics are not inert: they gradually break into fragments over time, forming micro- and then nanoplastics (i.e., particles

Phys.org / Predictive 'mismatch' leads to novel carbon capture method

When experimental results don't match scientists' predictions, it's usually assumed that the predictions were wrong. But new research into materials that pull carbon dioxide directly from the air shows how such mismatches ...

Phys.org / Leaves' pores explain longstanding mystery of uneven tree growth in a carbon-enriched world

The basics of photosynthesis are something that every student learns in school: carbon dioxide, water and light in; oxygen and sugar for growth out. In a world where atmospheric carbon dioxide levels are rising, it is plausible ...

Phys.org / East Antarctic Ice Sheet's history tells a relevant story for today and beyond

Though ice sheet melting is widely talked of and debated, there is limited knowledge about what happens after the period of melting. Researchers dig into this "after" period and see how it relates to previous patterns.

Phys.org / Smile and the world will trust you: How mimicry shapes first impressions

How does mimicry affect the way we judge other people? Whose behavior do we imitate, and in what situations? It turns out that we are more likely to mimic people who express joy, and we perceive those people as more attractive ...

Phys.org / Cells reveal 'survival of the fittest' through ribosome competition

Ribosomes—the tiny factories that build proteins in our cells—don't all work with the same efficiency. Researchers from Japan have discovered that ribosomes actually compete with one another, and those that perform poorly ...
