For the first time, scientists can distinguish the proportion of bromoform molecules that directly break bonds (dissociate) vs. those that rearrange (isomerize). This is an important step toward understanding the formation of bromoform isomers, which had long been predicted but had not been fully experimentally confirmed.

In this week鈥檚 Physics of Fluids, researchers study how Champatis roll and bounce down inclines. The authors released a heap of the seeds down an inclined plane while a camera recorded their descent to analyze their speed and the dynamics of their movement. The grains start to spread out slowly, then decrease quickly as they move downstream, akin to rock avalanches.

In this week鈥檚 Physics of Fluids, researchers employ machine learning to more accurately model the boundary layer wind field of tropical cyclones. Conventional approaches to storm forecasting involve large numerical simulations run on supercomputers incorporating mountains of observational data, and they still often result in inaccurate or incomplete predictions. In contrast, the author鈥檚 machine learning algorithm is equipped with atmospheric physics equations that can produce more accurate results faster and with less data.

Up until recently, habituation 鈥� a simple form of learning 鈥� was deemed the exclusive domain of complex organisms with brains and nervous systems, such as worms, insects, birds, and mammals. But a new study, published Nov. 19 in Current Biology, offers compelling evidence that even tiny single-cell creatures such as ciliates and amoebae, as well as the cells in our own bodies, could exhibit habituation akin to that seen in more complex organisms with brains.

A few years back, a group of weed scientists showed that soil-applied herbicides are less effective against agricultural weeds in the context of our changing climate. Now, the same research group, led by the USDA Agricultural Research Service and the University of Illinois Urbana-Champaign, has shown the same is true of post-emergence (POST) herbicides.
