Fungus Cell Looks Like The 405 Freeway

UCLA [ Watch the Video Nuclear dynamics in a fungal chimera ] No, those are not cars darting along a busy highway. The glowing specks you're seeing in this video are millions of nuclei flowing through the tube-like filaments, or hyphae, of a single fungus cell. The video was produced as part of a study by UCLA mathematician Marcus Roper's research group that was the first to measure and explain this dynamic movement of nuclei in the cells of a fungus. "It's complex, beautiful and...

Organisms In 33.6 Million Year Old Ice Pack Evolved To Survive

Lawrence LeBlond for redOrbit.com - Your Universe Online Researchers publishing a paper in the latest issue of the journal Science have found through Antarctic planktonic ice core examinations that the continental ice cap formed more than 33 million years ago. Scientists from the Andalusian Institute of Earth Sciences (IACT), a joint collaboration between the University of Granada and the Spanish National Research Council (CSIC), said the seasonal primary productivity of planktonic...

Evolution Of Multicellular Life Sparked By Bacteria
2012-10-24 13:36:16

Bacteria have a bad rap as agents of disease, but scientists are increasingly discovering their many benefits, such as maintaining a healthy gut. A new study now suggests that bacteria may also have helped kick off one of the key events in evolution: the leap from one-celled organisms to many-celled organisms, a development that eventually led to all animals, including humans. Published this month in the inaugural edition of the new online journal eLife, the study by University of...

This classification conveys important information about the biochemistry and metabolism of disease-causing organisms. Here are three examples. 1) Pneumocystis, an opportunistic pathogen causing mortality in AIDS patients and immunocompromised individuals, is now known to be a fungus, indicating a different treatment regimen is needed. 2) Phytophtora, an organism causing potato blight, such as the one that caused the Irish famine in the 19th century, is now known not to be a fungus, which...

WASHINGTON -- A one-celled creature found on a sandy beach may be in the process of kidnapping and incorporating an even tinier plant to use as a living energy source, Japanese researchers reported on Thursday. They said the newly discovered organism seems to be in the process of endosymbiosis -- in which one creature incorporates another, creating a new form of life. Scientists believe this is how many modern plants and animals evolved. They believe the chloroplasts, the green solar power...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
