"Because previous studies suggested an affinity between Cerataspis and penaeoid shrimp, and more specifically the family Aristeidae, we sampled heavily within these groups," Crandall explained. His lab had been collecting crustacean DNA informatio
This video by NASA’s Solar Dynamics Observatory captures a dramatic filament eruption on Aug. 31. Shown in the video in extreme ultraviolet light, the filament collapsed and exploded in spectacular fashion. The segment shown in red covers nearly 3 ho
This scenario represents an incomparably more challenging task, since most techniques for studying life were developed using examples existing on Earth. Did the entity use DNA, RNA and proteins to store and utilize genetic information? How can one be
Dubbed the Phoenix Cluster by the scientists that studied its properties, the incredible stellar mass, officially listed as Cluster SPT-CLJ2344-4243, spews out more than 700 new stars a year and is one of the most intense X-ray producing clusters in

his happened night after night. Then I noticed the sounds of something dropping out of the trees and an animal or being of some kind scraping on the bark a bit as it descended. I tried looking for movement but saw nothing, like an animal or anything.
Aerographite has a density of less than 0.2 milligrams per cubic centimeter, which allows it be compressed by a factor of 1,000, then subsequently spring back to its original state. Despite its extremely low density, it is black and optically-opaque
They are looking at the concept of moving the space instead of the spacecraft-that is to say, contracting space-time in front of the ship, with a commensurate expansion of the space-time behind it. NASA's Breakthrough Propulsion Physics Project is l
The job of the conscious mind is to form a story out of all our sensations and reflections. Life as we experience it is not just a series of unconnected thoughts and events; it's a coherent narrative unfolding in an orderly universe. But sometimes w
around 950 to 1250 C.E. While this time period is known as being a "dry period," the Pitt researchers have discovered an unexpected complexity to the patterns of drought.

The researchers looked instead for signs of a chemical drilling strategy, testing for the presence of acid-secreting enzymes in different tissues of the worm. One of the enzymes, a proton pump, was abundant in the roots, the part of the worm that pen
After a quest spanning nearly half a century, physicists on Wednesday said they had found a new sub-atomic particle consistent with the elusive Higgs boson which is believed to confer mass. Rousing cheers and a standing ovation erupted at the Euro
As physicists at Europe’s Large Hadron Collider prepare topresent their latest update in the hunt for the Higgs boson — the strange particle that exists everywhere in space and interacts with all other elementary particles, giving them their mass — o
Though the principle is identical to that used by a police speed gun, the technology that comprises the high-resolution radar is rather more powerful. The 3 MW radar emits microwaves with a 0.22-degree beam-width, which allows it to interrogate a 14
ASA's Lunar Reconnaissance Orbiter essentially illuminated the crater's interior with infrared laser light, measuring how reflective it was. The crater's floor is more reflective than that of other nearby craters, suggesting it had ic
Sonia Barrett is globally recognized for her unique, in-depth and humorous style of explaining the nature of reality as not only a virtual reality but ultimately a game. In 1992, a newly divorced single mother of two sons, Sonia Barrett set out to pr
The radiation burst, which seems to have hit between ad 774 and ad 775, was detected by looking at the amounts of the radioactive isotope carbon-14 in tree rings that formed during the ad 775 growing season in the Northern Hemisphere. The increase in
Although the fibers are present only inside the bone, mycologists were consulted in an attempt to identify them as a fungus or other organism. They reported that it did not appear to be a biological contamination. Nothing like this has ever been seen
An international team of researchers discovered that the body's copying machine for DNA works in the same way for manmade, artificial building blocks of DNA as it does for the natural kind. If scientists find artificial DNA building blocks wo

White Americans' heads are getting bigger. That's according to research by forensic anthropologists at the University of Tennessee, Knoxville. Lee Jantz, coordinator of UT's Forensic Anthropology Center (FAC); Richard Jantz, professor emeritus and
Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, whi
The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage and kill stately pine, spruce and other trees.
The research, published in the journal Nature Communications, has a range of fundamental implications for global ecology and allows researchers to estimate original leaf sizes from just a fragment of a leaf. This will improve scientists' prediction
scientists estimate there has been as much as a 60 per cent reduction in the volume of Antarctic Bottom Water, the cold dense water that drives global ocean currents.
In “a dramatic demonstration of mind reading, neuroscientists have created videos of what a cat sees by using electrodes implanted in the animal’s brain. ‘Trying to understand how the brain codes information leads to the possibility of re
The ancient Egyptians wrote calendars that marked lucky and unlucky days. These predictions were based on astronomical and mythological events thought of as influential for everyday life. The best preserved of these calendars is the Cairo Calendar
Geologists have long known that Earth’s core, some 1,800 miles beneath our feet, is a dense, chemically doped ball of iron roughly the size of Mars and every bit as alien. It’s a place where pressures bear down with the weight of 3.5 million atmosphe
