Imagine if a plant in a farmer’s field could warn a grower that it needs water? Or if a farmer could signal to plants that dry weather lies ahead, thereby prompting the plants to conserve water?

It may sound extraordinary, but researchers at the Center for Research on Programmable Plant Systems (CROPPS) have taken a major step toward advancing such two-way communication with plants.

A new study, published in the Proceedings of the National Academy of Sciences, has solved a century-old conundrum of how plants internally signal stress. By understanding how plant communication systems work, the team may then begin to exploit those signals to create plants that can communicate with people and each other, and be programmed to respond to specific stressors.

Max Karl Ernst Ludwig Planck (/ ˈ p l æ ŋ k / ; ^{[ 2 ]} German: [maks ˈplaŋk] ^ⓘ ; ^{[ 3 ]} 23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918. ^{[ 4 ]}

Planck made many substantial contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of quantum theory and one of the founders of modern physics, ^{[ 5 ] [ 6 ]} which revolutionized understanding of atomic and subatomic processes. He is known for the Planck constant, which is of foundational importance for quantum physics, and which he used to derive a set of units, today called Planck units, expressed only in terms of fundamental physical constants.

Planck was twice president of the German scientific institution Kaiser Wilhelm Society. In 1948, it was renamed the Max Planck Society (Max-Planck-Gesellschaft) and nowadays includes 83 institutions representing a wide range of scientific directions.

Perovskite photovoltaics (PV) are poised at the brink of commercialization, yet stability remains the foremost hurdle to overcome for widespread adoption. While extensive research has addressed the degradation of perovskite PV through accelerated indoor testing, outdoor testing remains relatively underexplored and primarily focused on small cells rather than modules.

This gap underscores the urgent need to comprehensively study outdoor degradation processes. Understanding how perovskite PV modules perform under real-world environmental conditions is crucial for advancing toward commercial viability.

In our work published in ACS Energy Letters, we present a two-year outdoor evaluation of perovskite modules, shedding light on their degradation under real-world conditions. Our findings highlight a significant milestone in perovskite PV research, with the most robust module maintaining 78% of its initial performance after one year. Performance loss rates during the burn-in period were found to be about 7%–8% per month.

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of single cells, simultaneously. Detecting the location of hundreds or thousands of biomolecules—from lipids to metabolites to proteins—in their native environment allows researchers to better understand their functions and interactions. Unfortunately, scientists don’t have great tools to accomplish this task.

Now a multi-institutional research team has developed a tissue expansion method that enables scientists to use mass spectrometry imaging to simultaneously detect hundreds of molecules at the single cell level in their native locations. Their paper is published in the journal Nature Methods.

Imaging methods, including most types of microscopy, provide a view of molecules inside cells. But they can track only a select handful of molecules at one time, and they can’t detect all types of biomolecules, including some lipids. Other methods, like regular mass spectrometry, can detect hundreds of molecules but don’t work on intact samples, so researchers can’t see how the biomolecules are oriented.
