Phys.org / How soil and human antibiotic resistance are connected

A study led by researchers at the Department of Civil Engineering at The University of Hong Kong (HKU) has uncovered alarming evidence that soil worldwide is emerging as a significant reservoir and amplifier of high-risk ...

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 / Ancient sea anemone sheds light on animal cell type evolution

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A neuron doesn't look nor behave ...

Phys.org / Deepest gas hydrate cold seep ever discovered in the Arctic at 3,640 m depth

A multinational scientific team led by UiT has uncovered the deepest known gas hydrate cold seep on the planet. The discovery was made during the Ocean Census Arctic Deep–EXTREME24 expedition and reveals a previously unknown ...

Phys.org / The dual impact of stellar bars on star formation in galaxy pairs

Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its neighboring galaxy, it ...

Phys.org / An ecosystem never forgets: Extreme heat and drought responses linked to hydrological memory

The low-latitude highlands region of southwestern China experienced two major climate events in recent years: a severe drought in 2009–2010 and an extreme heat wave in 2019. Though both sprang from similar large-scale atmospheric ...

Phys.org / The sound of droplets striking water: How cowbirds control two sound sources in the syrinx to create 'liquid notes'

Cowbirds are special among songbirds for the "watery" timbre of their singing, which resembles the sound of falling droplets striking water, a quick burst followed by a fading ripple.

Phys.org / Capturing the moment a cell shuts the door on free radicals

For the first time, researchers have been able to show how a cell closes the door to free radicals—small oxygen molecules that are sometimes needed, but that can also damage our cells. The study is published in Nature Communications ...

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 ...

Phys.org / Warming may make tropical cyclone 'seeds' riskier for Africa

An existing body of research indicates that climate change is making tropical cyclones wetter and more powerful. Now, a new study is indicating the same thing may be happening to the precursors of these storms: the wet weather ...
