Researchers quantify the way rivers bend, opening up the possibility for identifying origins of channels on other planets
Whether it's rivers cutting through earth, lava melting through rock, or water slicing through ice, channels all twist and bend in a seemingly similar back-and-forth manner. But a new study has discovered that channels carved by rivers actually have curves distinct to those cut by lava or ice.

New study examines how physics students perceive recognition
Experts see peer recognition as important to student success in physics, and a new study gives college-level physics instructors insight into how students perceive the message from their classmates that 'you're good at physics.' Even when women receive similar amounts of recognition from peers as men for excelling in physics classes, they perceive significantly less peer recognition, the researchers found.

Footprints of deep-sea mining
Mining of polymetallic nodules from the seabed might lead to significant and long-lasting ecological changes -- both in the mined area, where surface sediments and the fauna living in and on it are removed along with the nodules, and on the adjacent seafloor, where the sediment suspended by the mining resettles.

A method to purify proteins with light: Gentler and more efficient than previous procedures
Proteins play a key role in the life sciences -- from basic research and biotechnological applications to the development and manufacturing of pharmaceuticals. Scientists have developed a method that relies on physics rather than conventional chemistry to obtain the proteins that are needed for this purpose. Using short-wave, UV light invisible to humans, they have succeeded in purifying proteins from cell extracts or cultures. This technique is more efficient and gentler than previous methods.

Neural network deciphers gravitational waves from merging neutron stars in a second
Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers presents a novel machine learning method that can analyze gravitational waves emitted by neutron star collisions almost instantaneously -- even before the merger is fully observed. A neural network processes the data and enables a fast search for visible light and other electromagnetic signals emitted during the collisions. This new method could be instrumental in preparing the field for the next generation of observatories.

Using computer science to save the bees
Researchers have created a system to help beekeepers monitor and analyze the health of their beehives and take corrective actions to prevent colony collapse -- when a majority of the worker bees abandon the colony and its queen. Beehives use thermoregulation to ensure the hive temperature stays between 33 and 36 degrees Celsius, about 91 to 97 degrees Fahrenheit. For example, bees might cluster to create insulation when it's cold or fan their wings when it's hot. But when beehives experience external stressors, such as pesticides or unexpected weather events, they lose the ability to regulate the hive temperature.
