Possible evidence of cell division, differentiation found in oldest known embryo fossils
10-12-2006 · EurekAlert!A group of 15 scientists from five countries has discovered evidence of cell differentiation in fossil embryos that are more than 550 million years old. They also report what appear to be cells about to divide. The discovery will be reported in the Oct. 13 issue of Science, in the article, "Cellular and Subcellular Structure of Neoproterozoic Animal Embryos."

- Treasure trove of fossils found in Kendall County cave
04-12-2007 · EurekAlert!
UIC geologists discovered and excavated fossils from a cave in a Kendall County limestone quarry that has shed new light on living conditions in the area some 310 million years ago. The find includes a fossil of the oldest known conifer in North America.

- Tiny genes may increase cancer susceptibility, Jefferson scientists find
05-23-2007 · EurekAlert!
New evidence indicates that small pieces of noncoding genetic material known as microRNAs (miRNAs), which play various roles in biological regulation, including development and cell differentiation, might influence cancer susceptibility. Researchers found that miRNAs appear to be frequently located near places in the mouse genome that affect such susceptibility, suggesting that differences in certain miRNAs may predispose some individuals to develop cancer.

- 'Carnivorous' Coelophysis Dinosaur Fossil Re-examined -- Last Meal Was Primitive Crocodile
10-02-2006 · ScienceDaily
Four American Museum of Natural History paleontologists have overturned a 1950s claim that a theropod dinosaur called Coelophysis was a cannibal that ate juveniles of its own kind, forcing a revision of a popular story of dinosaur behavior that has been repeated many times in the scientific literature, popular media, and museum exhibits. In order to test the well-known cannibal-Coelophysis hypothesis, the team re-examined the anatomy of the two celebrated Coelophysis fossils said to exhibit cannibalism, as well as the structure of the bone found in the abdominal cavity of one of the specimens.

- Fossil record reveals elusive jellyfish more than 500 million years old
10-30-2007 · EurekAlert!
Using recently discovered 'fossil snapshots' found in rocks more than 500 million years old, three University of Kansas researchers have described the oldest definitive jellyfish ever found. In a paper published in PLoS ONE on Oct. 31, the researchers describe four types of cnidarian fossils preserving traits that allow them to be related to modern orders and families of jellyfish. The specimens are about 200 million years older than the oldest previously discovered jellyfish fossils.

- HIV is a 'double hit' to the brain
08-15-2007 · EurekAlert!
New evidence reported in the August issue of Cell Stem Cell, a publication of Cell Press, offers a novel perspective on how the HIV/AIDS virus leads to learning and memory deficits, a condition known as HIV-associated dementia. A protein found on the surface of the virus not only kills some mature brain cells, as earlier studies had shown, but it also prevents the birth of new brain cells by crippling "adult neural progenitors," the new study finds.

- Researchers find 6,000-year-old fossil evidence
02-15-2007 · EurekAlert!
Researchers, including a paleoethnobotanist at the University of Missouri-Columbia, recently found fossil evidence in seven archaeological sites ranging from the Bahamas to present-day Peru that showed people were eating domesticated chili peppers as long as 6,000 years ago. This makes chili peppers one of the oldest domesticated food sources in the Americas. The study will be published in the Feb. 15 edition of the journal Science.

- How emotionally charged events leave their mark on memory
10-04-2007 · EurekAlert!
Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories. Surges of the stress hormone norepinephrine (also known as noradrenaline) that often accompany strong emotions spark a series of molecular events that ultimately strengthen the connections between neurons, the team reports in the Oct. 5, 2007, issue of the journal Cell, a publication of Cell Press.

- Scientists discover stage at which an embryonic cell is fated to become a stem cell
01-10-2007 · EurekAlert!
Cambridge scientists have discovered the stage at which some of the cells of a fertilized mammalian egg are fated to develop into stem cells and why this occurs. The findings of the study, which overturn the long-held belief that cells are the same until the fourth cleavage (division) of the embryo, are reported in today's edition of Nature.

- Embryo fossils reveal animal complexity 10 million years before Cambrian Explosion
10-12-2006 · EurekAlert!
Fossilized embryos predating the Cambrian Explosion by 10 million years provide evidence that early animals had already begun to adopt some of the structures and processes seen in today's embryos, say researchers from Indiana University Bloomington and nine other institutions in this week's Science.

- Oldest complex organic molecules found in ancient fossils
10-25-2006 · EurekAlert!
Ohio State University geologists have isolated complex organic molecules from 350-million-year-old fossil sea creatures -- the oldest such molecules yet found. The molecules may have functioned as pigments, but the study offers a much bigger finding: An entirely new way to track how species evolved.
