Gaming hardware is not often known for the tastefulness of its design, but the $150 Logitech G Pro Wireless Gaming Mouse bucks that trend—you could use this in public without drawing any undue attention to yourself.

The new mouse has been designed with the feedback of more than 50 pro gamers—including a pro Overwatch team that used it when it won the first Overwatch League—to ensure a comfortable size and shape. The gaming cred shows in a few places: it has a new 16,000 dpi sensor that can track movement at over 400 inches per second to enable quick, precise motion, and it can report its motion up to 1,000 times per second to ensure low latencies. Its low weight (80 grams) and lack of cable mean that it can be thrown around effortlessly, enabling the fastest reactions.

Though the new sensor boasts a high resolution, Logitech claims it uses one-tenth the power of its previous optical sensor. The result is that the mouse can last 60 hours on a single charge. This is enough to go many games—even a whole tournament—without having to worry about power.

In rodents fed high-fat diets, gut microbes boost hunger, trigger obesity

After several hints that gut microbes may be key players in the obesity epidemic, a new study provides a mechanistic explanation of how the intestinal inhabitants directly induce hunger, insulin resistance, and ultimately obesity in rodents.

After mice and rats were fed a high-fat diet, their gut microbes produced more acetate, a short-chain fatty acid made during bacterial fermentation. That acetate spread throughout the rodents’ bodies and into their brains where it activated the parasympathetic nervous system. This system, largely involving the vagus nerve, controls the body’s unconscious actions, such as digestion, excretion, and sexual arousal. By activating the parasympathetic nervous system, the microbe-made acetate spurred the rodents to produce more insulin, a hormone made by pancreatic β-cells that promotes calorie storage, as well as ghrelin, a hormone involved in hunger. The result was rodents that ate more developed insulin resistance—a precursor to diabetes—and became obese, the researchers report in Nature.

“This generates a positive feedback loop,” the authors conclude—which makes sense for foraging animals, they add. If a foraging animal stumbles upon a calorie-dense food in the wild, it would be advantageous if their gut signaled their brain to keep eating and store some energy, stocking up to survive leaner times. “However, in the setting of chronic exposure to calorically dense, abundant food, this gut microbiota–brain–β-cell axis promotes obesity and its related sequelae of hyperlipidaemia [high levels of lipids in the blood], fatty liver disease and insulin resistance,” the authors write.
