How did students' diets and behavior change after the expiration of a pandemic-era universal free school meal program in 2022? Researchers asked teachers for their observations of the impact on students and found that teachers ...
Phys.org / Small molecular substitutions reshape energy pathways behind aggregation-induced emission
Certain chemical substances, broadly called luminogens, have an inherent ability to emit light. Most fluorescent molecules emit light in solution but lose their emission in the solid state, where the molecules aggregate.
Phys.org / How Mercury formed its graphite crust and core
As the BepiColombo mission prepares to enter the final phase of its journey to Mercury, a series of studies conducted by researchers at the University of Liège and KU Leuven sheds new light on the early stages of the evolution ...

Medical Xpress / Early mitochondrial stress reveals potential mechanism for lasting heart protection
Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do much more—including acting as signaling hubs. Some signals that mitochondria send can reprogram the activity of the entire ...
Phys.org / Virus-like particles enable gene activity tracking over time in the same cells
In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However, these methods rely on killing the cell to ...
Phys.org / Antarctic expedition reveals why Southern Ocean clouds remain one of climate science's greatest challenges
The Southern Ocean plays a pivotal role in regulating Earth's climate, yet the clouds that blanket this remote region remain among the least understood features in atmospheric science. By controlling both incoming sunlight ...
Phys.org / Resin-mounted wallaby teeth reveal rare 1,200-year-old ornaments in Queensland
While sorting through animal bones in a rock shelter in Queensland, Australia, archaeologists came across a tooth where something was "not quite right." Stuck to the tip of its root was a blackish-brown ball of glue-like ...
Medical Xpress / Key path to Alzheimer's-like brain damage starts outside the brain
Immune cells that normally protect the body from damage by attacking foreign or infected cells are found in the brains of patients with Alzheimer's disease and related disorders at much higher levels than in healthy brains. ...
Phys.org / How a plant's refusal to self-pollinate could help India grow more of its own cooking oil
Most people assume plants reproduce through whatever pollen happens to land on them. This is not true. A collaborative research initiative involving the Indian Institute of Technology Gandhinagar (IITGN) has mapped and functionally ...
