CLIMATEWIRE | The drought-driven wedge of salt water creeping up the Mississippi River is deepening a mystery about one of the world’s mightiest waterways. How will climate change affect the river? There are relatively few scientific studies on how warming is reshaping the Mississippi, and even fewer on saltwater intrusion from the Gulf of Mexico. The… Continue reading Here’s Why Salt Water Is Invading the Mississippi and Whether It Will Happen More Often
How to Watch the Northern Lights and Other Awesome Auroras
Imagine standing under the starry vault, bundled against the cold, when the sky erupts overhead. Rippling curtains, ribbons and streamers of colors across the rainbow light up the night, shimmering and majestic and all eerily silent. That’s what it’s like to see a vivid auroral display, and being able to witness one for yourself is… Continue reading How to Watch the Northern Lights and Other Awesome Auroras
The AI Boom Could Use a Shocking Amount of Electricity
Every online interaction relies on a scaffolding of information stored in remote servers—and those machines, stacked together in data centers worldwide, require a lot of energy. Around the globe, data centers currently account for about 1 to 1.5 percent of global electricity use, according to the International Energy Agency. And the world’s still-exploding boom in… Continue reading The AI Boom Could Use a Shocking Amount of Electricity

Icy Oceans Exist on Far-Off Moons. Why Aren’t They Frozen Solid?
They’d based their prediction on the orbital dance of Jupiter’s largest moons. For every four orbits that Io completes, Europa makes two and Ganymede one. This orbital configuration, known as a resonance, causes Io to wobble back and forth, making its orbit elliptical. When Io is closer to Jupiter, the planet’s gravity yanks on it… Continue reading Icy Oceans Exist on Far-Off Moons. Why Aren’t They Frozen Solid?
The Mathematician Who Shaped String Theory
Eugenio Calabi was known to his colleagues as an inventive mathematician — “transformatively original,” as his former student Xiuxiong Chen put it. In 1953, Calabi began to contemplate a class of shapes that nobody had ever envisioned before. Other mathematicians thought their existence was impossible. But a couple of decades later, these same shapes became… Continue reading The Mathematician Who Shaped String Theory
Untested Legal Imagination’s the Mother of Trump and Jan. 6 Prosecutions
Above, President Trump speaks to supporters from the Ellipse, near the White House, on Jan. 6, 2021, ahead of that day’s mayhem. He never set foot on the Capitol grounds. By Julie Kelly, RealClearInvestigationsNovember 1, 2023 Donald Trump doesn’t know Thomas Robertson. But the former president’s fate appears inextricably tied to that of the former… Continue reading Untested Legal Imagination’s the Mother of Trump and Jan. 6 Prosecutions
Thirty Years Later, a Speed Boost for Quantum Factoring
Finding Factors Quantum computers derive their power from the peculiar way they process information. Classical computers use bits, each of which must always be in one of two states, labeled 0 and 1. Quantum bits, or “qubits,” can additionally be in combinations of their 0 and 1 states — a phenomenon called superposition. It’s also… Continue reading Thirty Years Later, a Speed Boost for Quantum Factoring
More Terror Suspects Reaching the U.S.: Here Are the Known Unknowns of the Biden Border Crisis
Above, migrants heading for the U.S. border on Monday from Tapachula, Mexico. How many could be terrorists? Experts think it’s a virtual certainty that more are coming. By James Varney, RealClearInvestigationsOctober 31, 2023 Hundreds of people on the FBI’s terrorist watchlist have almost certainly slipped into the United States amid millions of other illegal immigrants… Continue reading More Terror Suspects Reaching the U.S.: Here Are the Known Unknowns of the Biden Border Crisis
These Cells Spark Electricity in the Brain. They’re Not Neurons.
A brain is nothing if not communicative. Neurons are the chatterboxes of this conversational organ, and they speak with one another by exchanging pulses of electricity using chemical messengers called neurotransmitters. By repeating this process billions of times per second, a brain converts clusters of chemicals into coordinated actions, memories and thoughts. Researchers study how… Continue reading These Cells Spark Electricity in the Brain. They’re Not Neurons.
