The Psychology of Why Consumer Rewards Programs Suck You In

By   /  July 25, 2021  /  Science  /  No Comments

If the urge to punch the final hole in your coffee shop rewards card has you rerouting your walks, you’ve fallen for a loyalty program. The drive to reach a small “gift” — a free latte, a seat upgrade on a flight — is why businesses offer rewards programs in the first place. Luring people […]

Asteroids: What They Are and Where They Come From

By   /  July 25, 2021  /  Science  /  No Comments

When we think of the solar system, we tend to think of the Sun and the nine planets that orbit it. But there’s a lot more orbiting the Sun than just planets (and dwarf planets — we see you, Pluto!) Take asteroids, for example. Asteroids are the debris left over from the formation of the […]

Quantum Mechanics, Plato’s Cave and the Blind Piranha

By   /  July 25, 2021  /  Science  /  No Comments

My quantum experiment, which has consumed me for more than a year now, has dredged up a creepy, long-buried memory. It dates back to the late 1970s, when I was a housepainter living in Denver. One day I found myself in a grungy saloon on Denver’s dusty eastern outskirts. Behind the bar was an aquarium […]

Mysteries of the Oort Cloud at the Edge of Our Solar System

By   /  July 24, 2021  /  Science  /  Comments Off on Mysteries of the Oort Cloud at the Edge of Our Solar System

The Oort cloud represents the very edges of our solar system. The thinly dispersed collection of icy material starts roughly 200 times farther away from the sun than Pluto and stretches halfway to our sun’s nearest starry neighbor, Alpha Centauri. We know so little about it that its very existence is theoretical — the material […]

A molecular sensor for cholesterol in the human serotonin1A receptor

By   /  July 24, 2021  /  Science  /  Comments Off on A molecular sensor for cholesterol in the human serotonin1A receptor

Abstract The function of several G protein–coupled receptors (GPCRs) exhibits cholesterol sensitivity. Cholesterol sensitivity of GPCRs could be attributed to specific sequence and structural features, such as the cholesterol recognition/interaction amino acid consensus (CRAC) motif, that facilitate their cholesterol-receptor interaction. In this work, we explored the molecular basis of cholesterol sensitivity exhibited by the serotonin1A […]

A variable-gain stochastic pooling motif mediates information transfer from receptor assemblies into NF-κB

By   /  July 24, 2021  /  Science  /  Comments Off on A variable-gain stochastic pooling motif mediates information transfer from receptor assemblies into NF-κB

INTRODUCTION A limited number of transmembrane receptors expressed on the cell surface mediate crucial transmission of information between extracellular and intracellular signaling molecules. Key questions are understanding the mechanisms and limitations that underlie signal transmission, in particular for cytokine receptor signaling that is often deregulated in disease. The nuclear factor κB (NF-κB) signaling pathway is […]
