Penguin Poop Turns Snow Green

In Antarctica, some snow isn't white. It's red, or even bright green. The color comes from tiny algae living in the snow, and a new study says penguins help keep it green. Here's how. Penguins eat fish and krill at sea, then waddle back to land and leave plenty of poop, called guano, all over the snow. That guano is packed with a nutrient called phosphate, which works like fertilizer. Scientists sailed along the Antarctic Peninsula and scooped up colored snow near penguin colonies and far from them. Where the algae was green, there was far more phosphate. When food runs low, the algae turns red to protect itself from the sun. Why it matters: green snow soaks up about forty percent more sunlight than clean white snow, so it melts faster. The researchers say melt forecasts don't include this effect yet. Even penguin poop shapes the planet.

Why Prices Jumped in September

If filling up the car felt pricier last month, you weren't imagining it. The Bureau of Labor Statistics says prices for everyday goods and services rose 3.7 percent over the past year, up from 3.4 percent the month before. That measure is called the Consumer Price Index, a giant shopping basket the government prices every month. The big driver this time was gasoline. Gas prices jumped about nine percent in September alone, and that one item made up more than half of the whole increase. Over the year, gas is up about a third. There was some good news at the grocery store: food prices overall didn't change in September, and milk and beef actually got cheaper. Leave out gas and food, which bounce around a lot, and prices rose 2.6 percent over the year. Economists watch that number to see whether price increases are spreading.

Flu Season Starts Early

Flu season usually takes off around November. This year it's getting an early start. The CDC's latest weekly flu report says flu is still low across the country, but it has been climbing since late summer, higher than usual for this time of year. The West Coast is seeing the most. Nationally, about three and a half percent of lab tests came back positive for flu, and in one western region it was close to ten percent. Almost all the flu A virus scientists checked was one type, called H1N1. So what can you do? The CDC recommends a flu shot every year for everyone six months and older, ideally by the end of October, since protection takes about two weeks to build. Wash your hands, cover your coughs, and stay home when you're sick. And if you do get flu, call your doctor early, because flu medicines work best in the first couple of days.

NASA's Moon Base Takes Shape

NASA wants to do more than visit the Moon again. It wants to stay. The agency is building what it calls humanity's first lunar outpost, a Moon Base near the Moon's South Pole. Why there? Scientists think some craters there hold ice that has stayed frozen in shadow for a very long time, and ice could someday mean water, air and even rocket fuel. The plan goes step by step. Phase One runs from now through 2029, and robots go first: more than twenty robotic landings from companies like Blue Origin, Firefly, Intuitive Machines and Voyager. The very first lander, called Endurance, will aim for a ridge near Shackleton Crater. Its NASA cameras will record how rocket exhaust blasts the moon dust, because future landers will need to set down next to real buildings without sandblasting them. Robots scout and build first. Astronauts move in later.

Big Chill Sweeps the U.S.

Fall just showed up all at once. A strong cold front is sweeping across the country. Ahead of it, warm, wet air from the Gulf of Mexico is getting pushed up and squeezed out as heavy rain. NOAA's Weather Prediction Center has parts of the Southern Plains, including west Texas, at a level three of four risk for flooding rain. That means flash floods could pop up quickly, especially in cities and near creeks. Farther east, forecasters see a chance of strong storms in the Ohio Valley today and the Mid-Atlantic on Friday, with lightning, gusty winds and maybe a few tornadoes. Behind the front, temperatures drop fast. Some places could fall twenty to thirty degrees, and the higher hills of the Northeast may even see wet snow Saturday morning. The simple rule for flooded roads? Turn around, don't drown. Even shallow moving water can sweep a car away. Check your local National Weather Service office for updates.
