The origins of money: Researchers found that 70% of certain bronze objects from the early Bronze Age (3000-2100 BC) are indistinguishably the same weight, implying they were created to be interchangeable. Shaped like rings, ax blades, and ribs, they are thought to be the first evidence of currency.
Researchers from the Netherlands may have uncovered the origins of currency using a subfield called "psychophysics."

Surface boulder banding indicates Martian debris-covered glaciers formed over multiple glaciations
Significant debate exists whether the global population of Martian debris-covered glacier deposits formed continuously over the past 300 to 800 Ma, or whether they formed during punctuated episodes of ice accumulation during obliquity maxima (lasting ...

A simple vision test can predict whether a person with Parkinson’s disease will develop cognitive decline or dementia within 18 months.
Zarkali et al. identify two organizational gradients to structural-functional connectivity decoupling in Parkinson’s disease and relate spatial patterns of decoupling to the expression of neurotransmitter receptors. This study provides a framewo ...

Researchers surveyed 312 students found that while some students had concerns about the lack of privacy or their home environment, 41% of the 276 respondents cited their appearance, as their reason not to switch on their cameras on zoom.
Establishing camera use as the norm, explaining the reasons that cameras improve the class and employing active learning techniques could help improve students’ use of cameras during online classes, a new Cornell study suggests.

There's growing evidence that SARS-CoV-2 might cause the body to generate antibodies that attack its own tissues, perhaps explaining why some get so sick or for so long. Self-attacking ‘autoantibodies’ could be the key to understanding some of the worst cases of SARS-CoV-2 infection.
