Why cats prefer silver vine to catnip and other May highlights

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. May's list includes the discovery of a possible prehistoric mining site in the Pyrenees; a new species of tiny blue octopus; why cats seem to prefer silver vine to catnip; and why political polarization might behave like a phase transition, among other noteworthy stories.

High in the eastern Pyrenees is a prehistoric cave, excavated between 2021 and 2023. Based on analysis of artifacts uncovered at the site, a team of Spanish archaeologists believes this may have served as an ancient copper smelting spot, with far more frequent occupation by humans than previously thought. The researchers described these preliminary findings in a paper published in the journal Frontiers in Environmental Archaeology.

Pigeons May Sense Earth’s Magnetic Field Using Superparamagnetic Immune Cells in Their Livers

Lisowski et al. used physical, morphological, functional, and genomic assays to identify the presence of superparamagnetic macrophages in the liver of homing pigeons (Columba livia domestica). Image credit: Spanishguitar101 / CC BY-SA 4.0.

Scientists have identified supermagnetic macrophages in the livers of homing pigeons (Columba livia domestica) that appear essential for navigation when the Sun is not visible, pointing to an entirely new mechanism for animal magnetoreception.

Stress Can Literally Make You Lose Your Direction, According to New MRI Evidence

Confused Businessman Decision ClosePeople under stress may find it harder to orient themselves in space, and researchers in Bochum have identified a possible reason why. The stress hormone cortisol appears to interfere with the brain system that helps people navigate. It weakens the activity of grid cells, which are important for spatial orientation. Researchers at Ruhr University Bochum [...]

Scientists Uncover a Hidden Alzheimer’s Target and Create the First Tool To Control It

Neurons Damaged by Alzheimer's DiseaseTwo new tool compounds may help scientists study TAOK proteins linked to Alzheimer’s disease and other neurological disorders. Alzheimer’s disease is the leading cause of dementia and affects more than seven million people in the United States. Some treatments can slow the disease, but most address symptoms rather than the root biology, and none can [...]

Could aliens ever visit Earth?

On May 22, 2026, the Pentagon released a second batch of previously classified photos and videos showing what appear to be unexplained flying objects. These file dumps were the culmination of a process that was set in motion back in July 2023, when a group of government whistleblowers testified before Congress that the U.S. government was secretly inContinue reading "Could aliens ever visit Earth?"

Scientists May Have Found a Completely New Way To Treat Depression

Happy Smile Face Depression Breakthrough SuccessScientists may have found a completely new way to treat depression by targeting inflammation instead of brain chemistry. A small clinical trial led by researchers at the University of Bristol suggests that targeting the immune system could help people with depression who do not improve with standard antidepressant medications. The findings, published May 20 in [...]
