A team of scientists has discovered the youngest dinosaur preserved in the fossil record before the catastrophic meteor impact 65 million years ago. The finding indicates that dinosaurs did not go extinct prior to the impact and provides further evidence as to whether the impact was in fact the cause of their extinction. (more…)
EAST LANSING, Mich. — By honing in on the mysterious potato genome and its tuber – its edible portion – researchers are unveiling the secrets of the world’s most-important nongrain food crop.
Robin Buell, Michigan State University plant biologist, is part of an international research team that is mapping the genome of the potato. In the current issue of Nature, the team revealed that it accomplished its goal, thus quickly closing the gap on improving the food source’s elusive genome. (more…)
ANN ARBOR, Mich.—Physicists and astronomers have long believed that the universe has mirror symmetry, like a basketball. But recent findings from the University of Michigan suggest that the shape of the Big Bang might be more complicated than previously thought, and that the early universe spun on an axis. (more…)
*Looking in vivo at virus-bacterium associations sets stage for better understanding of such interactions in human health*
Viruses are the most abundant parasites on Earth. Well known viruses, such as the flu virus, attack human hosts, while viruses such as the tobacco mosaic virus infect plant hosts.
More common, but less understood, are cases of viruses infecting bacteria known as bacteriophages, or phages. In part, this is due to the difficulty of culturing bacteria and viruses that have been cut off from their usual biological surroundings in a process called in vitro. (more…)
PASADENA, Calif. — Scientists analyzing data from NASA’s Cassini spacecraft now have the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth.
On Dec. 5, 2010, Cassini first detected the storm that has been raging ever since. It appears approximately 35 degrees north latitude of Saturn. Pictures from Cassini’s imaging cameras show the storm wrapping around the entire planet covering approximately 2 billion square miles (4 billion square kilometers). (more…)
GAINESVILLE, Fla. — A new study co-authored by University of Florida researchers provides details on the first cookiecutter shark attack on a live human, a concern as warm summer waters attract more people to the ocean. (more…)
Woods Hole Oceanographic Institution (WHOI) researchers have filled an important gap in the study of tunicate evolution by genetically sequencing 40 new specimens of thaliaceans, gelatinous, free-swimming types of tunicates. Their study was featured on the cover of the June issue of the Journal of Plankton Research.
Tunicates are a phylum of animals closely related to vertebrates, with a firm, rubbery outer covering called a tunic, from which the name derives. (more…)
The sun and the solar system’s rocky inner planets, including the Earth, may have formed differently than previously thought, according to UCLA scientists and colleagues analyzing samples returned by NASA’s Genesis mission. (more…)
