The sea anemone is an oddball: half-plant and half-animal, at least when it comes to its genetic code, new research suggests.

look more like those of animals, but the regulatory code that determines whether those genes are expressed resembles that in plants, according to a study published Tuesday (March 18) in the journal Genome Research.
Spring dawns on the nothern hemisphere on March 20, 2014. NOAA's GOES-13 satellite caught this image of the first day of spring at 7:45 a.m. Eastern Daylight Time.

Chicken from hell?

A beaky, crested dinosaur nicknamed the "chicken from hell" has been discovered in both North and South Dakota.
This was not a "chicken" you'd want to…Read More »
stumble across in the barnyard: The new dino, dubbed Anzu wyliei, was about 11 feet (3.5 meters) long and about 10 feet (3 m) tall. It boasted a flashy head crest and probably wore feathers. Anzu wylieli lived at the same time as Tyrannosaurus rex, but was more lithe and graceful, said study researcher Emma Schachner.

NASA's Hubble Space Telescope has captured an amazing view of a distant starbirth factory, a nebula known as the "Monkey Head," to help celebrate the…Read More »
upcoming 24th anniversary of the iconic instrument's launch.
The new infrared mosaic from Hubble — which launched on April 24, 1990 — shows knotty curls of dust and gas in the Monkey Head Nebula, a star-forming region that lies about 6,400 light-years away from Earth and is also known as NGC 2174 and Sharpless Sh2-252. Scientists used the Hubble mosaic to create a spectacular video of the Monkey Head Nebula to explain the new cosmic views.

During Earth's last ice age, iron dust dumped into the ocean fertilized the garden of the sea, feeding a plankton bloom that soaked up carbon dioxide…Read More »
from the air, a new study confirms.
But the results deal a blow to some geoengineering schemes that claim that people may be able use iron fertilization to slow global warming. The planet's natural experiment shows it would take at least a thousand years to lower carbon dioxide levels by 40 parts per million — the amount of the drop during the ice age.
Hekla volcano, one of Iceland's most active volcanoes, could be close to erupting, a University of Iceland geoscientist claims.
The most prominent sign…Read More »
of an impending eruption is bulging ground on the northern side of the volcano. This surface swelling indicates magma (molten rock) is rising under the volcano, pushing up the ground as it fills fractures and pipes beneath Hekla. According to GPS monitoring of the expanding surface, there is now more magma underneath Hekla than before the volcano's last eruption in 2000, University of Iceland geophysicist Páll Einarsson said in a report published in the Icelandic newspaper Morgunblaðið on Monday (March 17). Hekla volcano "could erupt soon," Einarsson said.
A new telescope tool for peering into the cosmos and creating three-dimensional views of the universe has passed its first major test at a European observatory…Read More »
in Chile's high desert.
After a decade of design and development, the tool — called the Multi Unit Spectroscopic Explorer (MUSE) — successfully captured its first images of deep space to create 3D views of the early universe. Installed on the European Southern Observatory's Very Large Telescope (VLT) in Chile, MUSE can both study and image the depths of space.
Everyone knows cuckoos are the freeloaders of the animal kingdom, laying their eggs in other birds' nests. But such slackers may not be total parasites.

A study of great spotted cuckoos and the carrion crows that raise the cuckoos' young finds that young cuckoos secrete a noxious substance that repels predators that come to attack the nest. These results suggest cuckoos and crows have a mutually beneficial relationship.
