Researchers found that leftovers are likely to end up in the trash, so they advise cooking smaller meals in the first place to avoid food waste. Christopher Intagliata reports.

The finding of a baby dinosaur fossil in the Arctic implies that some dinos nested in the region, which was milder than today but not toasty.

Astronomers observed an odd triple-star system that offers clues about misaligned planetary orbits. Christopher Intagliata reports.

A study estimates that 200 million trees in the tropics are mowed down by lightning annually.

Here are some brief reports about science and technology from all over, including one from Antarctica about how there’s something funny about penguin poop.

Every year, Alaska’s big salmon runs feature smaller salmon. Climate change and competition with hatchery-raised salmon may be to blame. Julia Rosen reports.

That drought may have brought about societal shifts in the region 5,000 years ago. Christopher Intagliata reports.

The finding could potentially help wildlife managers keep better tabs on their herds. Jason G. Goldman reports. 

Researchers found extra bones within a 240-million-year-old ichthyosaur fossil—which they determined to be the ichthyosaur’s last, possibly fatal meal. Christopher Intagliata reports.

Butterflies, fish and frogs sport rear-end eyespots that reduce predation. Painting eye markings on cows similarly seems to ward off predators.

Hermit warblers in California have developed 35 different song dialects, apparently as a result of wildfires temporarily driving them out of certain areas.

Scientists determined that “lava world” exoplanets do not derive their brightness from molten rock but possibly get it from reflective metallic clouds. Christopher Intagliata reports.

Climate change is expected to bring more frequent droughts and heat waves to Africa’s Kalahari Desert. And aardvarks might not be able to cope. Jason G. Goldman reports.

Scientists spotted a mouse at the summit of Llullaillaco, a 22,000-foot-tall volcano on the border of Chile and Argentina. Julia Rosen reports.

A decline in smell was the sense loss most strongly associated with such risk in a recent study. Christopher Intagliata reports.

Rather than undergoing active chameleonlike color changes, glass frogs’ translucency allows light to bounce from their background and go through them—making their apparent color close to their setting. 

Compared with traditional lineup techniques, a series of two-faces-at-a-time choices led to more accurate identification by study witnesses.

An analysis of fox fossils found evidence that they scavenged from wolf and bear kills until Homo sapiens supplied plenty of horse and reindeer remains.

Now submerged caves in the Yucatán Peninsula contain remains of ocher-mining operations that date back at least 10,000 years.

Soap bubbles are sticky enough to carry a pollen payload and delicate enough to land on flowers without harm.
