Footage of a mob storming the Capitol on Jan. 6, 2021, in an effort to subvert the legal and peaceful transfer of power, filled many of us with horror. Underlying that response was our indignation at the brazen violation of central democratic institutions and values. We respond similarly to news of hate crimes, mass shootings,… Continue reading Are We Cut Out for Universal Morality? – Issue 100: Outsiders

I can’t see them. Therefore they’re not real.” From which century was this quote drawn? Not a medieval one. The utterance emerged in February 2019 from Fox & Friends presenter Pete Hegseth, who was referring to … germs. The former Princeton University undergraduate and Afghanistan counterinsurgency instructor said, to the mirth of his co-hosts, that… Continue reading Why Misinformation Is About Who You Trust, Not What You Think – Issue 100: Outsiders

These and other surprising examples made it clear that mathematicians needed to prove that dimension is a real notion and that, for instance, n- and m-dimension Euclidean spaces are different in some fundamental way when n ≠ m. This objective became known as the “invariance of dimension” problem. Finally, in 1912, almost half a century after Cantor’s… Continue reading The Journey to Define Dimension

Ford Motor Co. nearly tripled its electric vehicle sales last month, according to a company report. The auto giant increased its EV and hybrid sales this May by 184% compared to May 2020, marking a record number of 10,364 EVs sold in a given month, the sales report found. The significant increase is due in part to… Continue reading Electric Vehicle Orders Are Zooming at Ford

Imagine you’re a general in ancient times and you want to keep your troop counts secret from your enemies. But you also need to know this information yourself. So you turn to a math trick that allows you to achieve both aims. In a morning drill you ask your soldiers to line up in rows… Continue reading How Ancient War Trickery Is Alive in Math Today

After four years of an agenda that favored polluters, a new day is dawning at the Department of the Interior. In March, communities across the country rejoiced in Secretary Deb Haaland’s historic confirmation to lead the biggest and most powerful land management agency in the country. Now, she’s taking the opportunity to pursue real reforms… Continue reading Any Reform of Federal Oil and Gas Leasing Must Include Environmental Justice

But seismology is not omniscient. Seismic waves can detect structures within the mantle, but they cannot reveal every characteristic of those structures. “You can slow down a seismic wave by heating a material up,” said Harriet Lau, a geophysicist at the University of California, Berkeley. But a change in the rock’s mineral makeup can achieve… Continue reading A Massive Subterranean ‘Tree’ Is Moving Magma to Earth’s Surface

Instead of reaching for a cup of coffee during a graveyard shift, workers might one day hold an electric-razor-sized device to their necks. After a couple of minutes they would emerge refreshed and awake from this experience, which could come to be known as a “vagus nerve break.” The device, called gammaCore, sends a series… Continue reading Neck-Zapping Gadget Reduced All-Nighter Fatigue in New Study

The emerging picture does more than reconfigure our view of what biomolecules in our cells are up to as they build an organism — what logic they follow to create complex life. It might also help us understand why living things are able to survive at all in the face of an unpredictable environment, and… Continue reading Biologists Rethink the Logic Behind Cells’ Molecular Signals

A concentration of one part per billion is like a pinch of salt in 10 tons of potato chips—and scientists can now find radioactive particles at concentrations millions of times smaller. In the Journal of Analytical Atomic Spectrometry, researchers describe successfully detecting radioactive uranium and thorium hiding among something like a million billion other atoms.… Continue reading New Radioactivity Measurement Could Boost Precision of Dark Matter Experiments
