Simple animal model reveals how environment and state are integrated to control behavior

The neuron AWA stretches from the worm’s brain to its nose. Credit: Ian McLachlan/MIT Picower Institute Say you live across from a bakery. Sometimes you are hungry and therefore tempted when odors waft through your window, but other times satiety makes you indifferent. Sometimes popping over for a popover seems trouble-free but sometimes your spiteful … Read more

Melting temperature prediction using a graph neural network model

Credit: Pixabay/CC0 Public Domain If you apply enough heat, at some point, most things melt, just like ice cream on a hot summer day. Knowing exact melting temperatures is critical for building any high-performance material. The building and safety of bridges, gas turbines, jet engines and heat shields on aircraft are dependent on knowing the … Read more

Ancient megalodon super-predators could swallow a great white shark whole, new model reveals

The reconstructed megadolon was 16 meters long and weighed over 61 tons. Credit: JJ Giraldo In a new 3D modeling study published this week in Science Advances, we show that the giant extinct shark, Otodus megalodonwas a true globetrotting super-predator. It was capable of covering vast distances in short order, and could eat the largest … Read more

Transportation recovery after disasters: A collaborative university/community model

Credit: Unsplash/CC0 Public Domain Transportation systems play a critical role in maintaining supply chains for effective post-disaster recovery. The March 2020 COVID-19 lockdowns coincided with a 5.7 magnitude earthquake in Salt Lake City, Utah, resulting in supply chain disruptions throughout the region. A team of researchers collaborated with local agencies and transportation organizations to use … Read more

Complex coacervate droplets as a model material for studying the electrodynamic response of biological materials

Alamgir Karim, Dow Chair and Welch Foundation Professor of Chemical and Biomolecular Engineering, led the research team. Credit: University of Houston Manipulating solid particles of a few micrometers in size using an electric field has been of great interest to physicists. These controllable particles can be assembled into dynamic chains that can effectively control the … Read more

Stressed teachers find hope in peer-support model used by frontline health workers

Credit: Shutterstock Teachers are burning out and leaving the profession in numbers. Classrooms and workloads are challenging, made worse by staff shortages, and teachers are stressed. Student welfare needs to be prioritised, but the educators supporting them need support too. A model of peer support used by front-line health workers could provide a way forward. … Read more

New 3D model will help guide exploration for rare earth element deposits in alkaline igneous systems

A world map showing rare earth element-high field strength element (REE-HFSE) deposits and alkaline-silicate complexes mentioned in the main text. Alkaline-silicate complexes with and without carbonatite are shown in white, and systems containing major carbonatite-associated REE deposits are shown in gray. The crustal basement thickness map is an inversion of satellite gravity data (Alvey et … Read more

NASA’s solar forecast is turning out to be wrong. This team’s model is still on track.

Solar cycle 25 kicked off last year. Forecasters thought it would be a mild one, but it’s turning out to be quite the opposite. From its onset, this solar cycle has been steadily outpacing predictions, producing more sunspots and spinning way more solar wind, flares and eruptions than the world’s leading experts predicted. But while … Read more
