Venice, the "floating city" of romance and gondolas, is slowly sinking into its watery foundations.
A new study using modern satellite data has shown…Read More »
the amount that Venice is sinking with an unprecedented level of resolution, allowing scientists to tease apart the influence of natural causes of the sinking, due to compaction of the sediments on which the city is built, versus man-made ones, such as building restoration.

A newly discovered fish fossil is the earliest known creature with what might be recognized as a face.
Entelognathus primordialis was an ancient fish…Read More »
that lived about 419 million years ago in the Late Silurian seas of China. The finding, detailed today (Sept. 25) in the journal Nature, provides a link between two groups of fishes previously thought to be unrelated, challenging long-held notions of how vertebrate faces evolved.
was taken in Bozeman, Montana, while Kvackay was shooting a series of time-lapse images on a small pond.
"I heard some thunder in the distance and was about to stop shooting when I saw that lightning bolt," Kvackay told LiveScience. "I didn't think much of it, but wanted to get my slider and two tripods back in my car before it started to storm. I checked my camera in the car and found that I caught that shot."
Kvackay caught a lucky break, he said, as he had stopped the time-lapse only a few seconds after the lightning bolt struck.

A new camera on a telescope in the Southern Hemisphere has captured a stunning view of the Cat's Paw Nebula, offering a colorful and detailed view of…Read More »
a star-forming region of the Milky Way.
Released by the European Southern Observatory, the new photo of the Cat's Paw Nebula located about 5,500 light-years from Earth is one of the first shots taken by ArTeMiS — a submillimeter-wavelength camera added to APEX, the Atacama Pathfinder Experiment in Chile. ESO officials also produced a video fly-through of the incredible Cat's Paw Nebula view using the new camera observations.
A perplexing fast-spinning star just might be the "missing link" in a long-standing pulsar mystery, scientists say.
The so-called neutron star — a city-sized…Read More »
stellar remnant born from the explosive death of a larger star — is located about 18,000 light-years from Earth has the never-before-observed ability to change from one kind of pulsar to another and back again. You can watch a video animation of the pulsar here set to the music of rock band Atom Strange.

certainty to emerge in such areas as sea level rise and global temperature increases.
Climate scientists are generally pleased with the evolution of and output of the group, though some would like to see stronger messages from it. Some scientists also want to cut down the timescale of the massive operation, which takes several years and is done on a volunteer basis by scientists.
Anybody wondering what Earth was like 4 billion years ago should cast an eye toward Jupiter's hypervolcanic moon Io, a new study suggests.
Io is the most…Read More »
volcanically active object in the solar system, dissipating its massive stores of internal heat via intense eruptions that cover the entire moon with about 0.4 inches (1 centimeter) of lava every year. Earth probably went through a similar phase in its youth, back before the planet cooled enough for plate tectonics to start up, researchers report today (Sept. 25) in the journal Nature.
In Bering Land Bridge National Preserve, gone are the shockingly bright pinks, yellows and purples of summer. They've been replaced by deeper and darker reds, yellows, greens and the beginnings of brown. The days are a crisp 34 degrees Fahrenheit (1 degree Celsius). With daylight slowly diminishing, visitors to this Alaskan wilderness must enjoy the color while they can, because soon a blanket of white will fall upon the landscape.
The Bering Land Bridge National Preserve is one of the most remote U.S. national parks. It is a wilderness dotted with hot springs, ancient lava flows and the largest maar lakes (caused by a kind of volcanic eruption) in the world.
In rare cases, one of life's important childhood lessons — always chew your food properly — becomes fossilized. And now, anyone can own one of these reminders…Read More »
in rock. A specimen containing the remains of a large, predatory amphibian choking on another creature is up for auction in October.
Nearly 300 million years ago, during the Paleozoic Era, this predator attempted to eat another, smaller amphibian. The larger creature died mid-meal with the smaller one's body half-consumed. This type of fossil, in which a predator chokes on its prey, is known as an aspiration.
Most animals have a circadian clock that helps them distinguish night and day, but now researchers have found coastal animals seem to be equipped with…Read More »
a separate clock to track time via the tides.
The evidence comes from the discovery of internal clock genes that help some marine animals track the ebb and flow of the tides, according to two studies detailed today (Sept. 26) in the journals Current Biology and Cell Reports.
