Chemists repurpose blockchain mining for creating a vast network of prebiotic reactions.

A leading scientific journal group will implement AI-based quality control program to screen for doctored images in research submitted for publication.

<p>In work published in the prestigious Cell Press journal <em>Chem</em>, UMaine theoretical physicist R. Dean Astumian and collaborators Ayusman Sen and Niladri Sekhar Mandal at Penn State have published a different mechanism by which single molecules can interact non-reciprocally without hydrodynamic effects. This mechanism invokes the local gradients of reactants and products due to the reactions facilitated by every chemical catalyst, a biological example of which is an enzyme. Because the response of a catalyst to the gradient depends on the catalyst&rsquo;s properti...

<p>Arctic seals have evolved many adaptations to cope with their frosty environment&mdash;one that you might not immediately think of is the bones in their nasal cavity. Arctic seals have more convoluted nasal passages than seal species that live in milder environments, and researchers report December 14 in the <em>Biophysical Journal </em>that these structures help the seals more efficiently retain heat and moisture as they breathe in and out.</p>

<p>While the lithium-ion batteries in disposable electronic cigarettes are discarded after a single use, they can continue to perform at high capacity for hundreds of cycles, according to a study published December 12 in the journal <em>Joule</em>. The analysis, conducted by scientists from University College London and the University of Oxford and supported by The Faraday Institution, highlights a growing environmental threat from these increasingly popular vape pens, which are not designed to be recharged.</p>
