As oceans heat up, the ubiquitous noise of snapping shrimp should increase, posing issues for other species and human seagoing ventures.

In an example of how sea noise can harm species, exposed shore crabs changed camouflaging color sluggishly and were slower to flee from simulated predators.

Studies on very old vegetation in the Amazon basin show active management hundreds of years ago on species such as Brazil nut and cocoa trees.

By breaking 900 classical piano compositions into musical chunks, researchers could track Ludwig van Beethoven’s influence on the composers who followed him. Christopher Intagliata reports. 

Here are a few brief reports about science and technology from around the world, including one from off the California coast about the first heart rate measurement done on a blue whale.

Increasing or decreasing the altitude of aircraft by a few thousand feet to avoid thin layers of humidity could make a major reduction to contrails’ contribution to climate change.

Inbreeding in Thoroughbreds has increased significantly in the past 45 years, with the greatest rise occurring in the past 15 or so of them.

Hippos that escaped from drug kingpin Pablo Escobar’s private zoo are reproducing in the wild. And with increasing numbers, they could threaten ecosystems.

Art created by Australian Aboriginal people used organic carbon-free pigments, but wasp nests above or below the art can be used for radiocarbon dating that supplies boundaries for the age of artworks.

Ice cores from a Tibetan glacier reveal the first deposits of industrial revolution pollution, starting in layers dated to about 1780.

A new study in mice concludes stress can cause gray hair—and credits overactive nerves with the change in hue. Karen Hopkin reports. 

A very fine grind can actually hamper espresso brewing, because particles may clump more than larger particles will.

Most feral dogs that did not run away from humans were able to respond to hand cues about the location of food—even without training.

Neandertals ate clams and then modified the hard shells into tools for cutting and scraping.

Whiskeys claimed to be from the 19th century are revealed to be made with much more recently grown barley, thanks to the unique isotopic fingerprint of the nuclear-testing era. 

By outfitting 169 albatrosses with GPS data loggers, scientists were able to track fishing boats apparently trying to hide their location. Christopher Intagliata reports.

Here are a few brief reports about international science and technology from around the world, including one from the Democratic Republic of the Congo about a toad that has evolved coloring that makes it look like a deadly snake’s head.

Groundhogs are less accurate at weather forecasting than are coin flips, but they are nonetheless pretty interesting critters.

One hypothesis says the ability to vocalize arose in nocturnal animals—and a new evolutionary analysis suggests there may be some truth to it. Christopher Intagliata reports. 

Well more than 100 distinct sign languages exist worldwide, with each having features that made it possible for researchers to create an evolutionary tree of their lineages.
