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.

Prehistoric mining in the Pyrenees

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.

SpaceX, China set for busy launch week

What’s launching this week Early this morning, Monday, June 1, the state owned China Aerospace Science and Technology Corporation (CASC) successfully completed the maiden flight of the reusable Long March 12B — a two-stage, 236-foot (72-meter) rocket powered by nine liquid oxygen and kerosene engines with a 44,000-pound (20,000 kilogram) payload capacity. The mission launchedContinue reading "SpaceX, China set for busy launch week"

Microsoft's Surface Laptop Ultra looks like its first true MacBook Pro competitor

Dell, Asus, Lenovo, HP, MSI, Acer, and Gigabyte are among the PC makers that are designing systems around Nvidia's RTX Spark, Nvidia's new Arm-based chip for Windows PCs. But the flagship RTX Spark PC may be from the same company that makes Windows: the new Microsoft Surface Laptop Ultra is a high-end RTX Spark system that will offer up to 128GB of unified memory for "creators, developers, and AI builders."

Microsoft says the Laptop Ultra will be available "later this year" but didn't discuss any specific pricing or configuration options.

The Laptop Ultra will slot in above the regular Qualcomm Snapdragon-based Surface Laptops in Microsoft's lineup. Microsoft has made high-end Surface devices with more powerful CPUs and GPUs before, but to date, they've also come with convertible designs that may have limited their appeal. The first was the old Surface Book, with its fully detachable screen and bendy-straw hinge that didn't close all the way; the second was the Surface Laptop Studio, with its chunky design and sliding screen. The Laptop Ultra is Microsoft's first attempt to follow the MacBook Pro formula: it's like the other Surface Laptops, just with more power.

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.

Dozens of Red Hat packages backdoored through its official NPM channel

Official Red Hat NPM accounts have been compromised and used to push a malicious worm that spreads from machine to machine, where it pilfers sensitive credentials in hopes of stealing yet more confidential data, researchers said.

The supply-chain attack began Monday and remained active at the time this post went live, according to researchers at security firm Aikido. It’s the result of the threat actor responsible for the hack taking control of @redhat-cloud-services, a legitimate channel in the npm repository that’s reserved for official Red Hat packages. As such, the channel is widely trusted by developers who rely on Red Hat cloud services.

The vicious cycle of today’s supply-chain attacks

It’s unclear precisely how the threat actor took control of the namespace, but it almost certainly involved the compromise of credentials required to access it, possibly through a previous supply-chain attack. More than 30 packages seem to be affected.

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 [...]
