The immune system, the body's defense network against infections and injuries, can sometimes become too active. In these cases, it can produce too many immune mediators, fragments of genetic material or proteins that regulate immune responses.
If you've driven down two-lane highways in rural parts of North Florida recently, you may have noticed a spate of new signs that designate the grassy knolls bordering the asphalt as wildflower areas. The signs likely feel redundant right about now as thousands of milkweeds produce thick umbels packed full of pentagonal buds and fully developed flowers. Many of these flowers and all the monarchs they attract have the same attention-grabbing orange color as the safety vests worn by workers who carefully planted each milkweed by hand months earlier.
More than 2,700 people are estimated to have died from heat-related causes during the record-breaking May and June 2026 heat waves in England and Wales, according to a new rapid analysis report led by researchers from the London School of Hygiene & Tropical Medicine (LSHTM), Imperial College London and the Met Office.
Researchers at Washington State University have discovered a molecular "winter lock" that keeps animals in a less active winter state until favorable conditions return, a discovery that could improve pest control and lead to a better understanding of seasonal health conditions in humans.
People experiencing homelessness, victims of domestic violence and economically vulnerable people are at higher risk of social exclusion. For them, pets are an important source of emotional support. A study by the Affinity Foundation Chair for Animals and Health of the Universitat Autònoma de Barcelona (UAB) and the FAADA Foundation, published in the Frontiers in Psychology journal, highlights the importance of this support from a multidimensional perspective, drawing on the experiences of 100 individuals in vulnerable situations.
In a research lab at the University of Tokyo, scientists have developed a new kind of glue. It's incredibly strong and highly stretchable, yet it washes away completely with a little alcohol.
Ireland's waters continue to provide an important seasonal refuge for the endangered basking shark, according to a new study.
If you want to beat the heat of the summer sun, slowing down and doing less is a good strategy. However, researchers have long asked whether the same occurs at the cellular level. While cellular stress responses have been repeatedly studied, the impact of the environment on these responses remains relatively unknown.
Quantum computers, devices that process information by leveraging the laws of quantum mechanics, have been found to outperform classical computers in some advanced tasks. Instead of storing information in the form of classical binary bits (i.e., 0 or 1), quantum computers rely on quantum bits (i.e., qubits), which can also exist in combinations of 0 and 1 states.
India's first privately built orbital rocket took its maiden flight Saturday, its company said, marking a significant step for the South Asian giant as it eyes a bigger slice of the global space economy.
