Genome of marine organism tells of humans' unicellular ancestors
02-14-2008 · EurekAlert!A ubiquitous but little-known marine organism, the choanoflagellate, is the last one-celled ancestor of humans and provides insight into how cells learned to assemble into multicelled organisms. The genome of the choanoflagellate Monisiga brevicollis has now been sequenced and, according to UC Berkeley's Nicole King, offers clues to the origin of the glue that holds many-celled animals together and how cells learned to communicate.

- Sea anemone genome provides new view of our multi-celled ancestors
07-05-2007 · EurekAlert!
The genome of the starlet sea anemone is nearly as complex as the human genome, according to UC Berkeley and Joint Genome Institute researchers who have completed the first analysis of the animal's genes. Because of this similarity, it is providing major insights into the common ancestor of eumetazoans, a group that includes not only humans and sea anemones, but nearly all multi-celled animals.

- A prickly subject: The sea urchin genome is sequenced
11-09-2006 · EurekAlert!
The sea urchin revealed a number of surprising details about its genetic makeup and its similarity to humans in a paper announcing the completed sequencing of the organism's genome in today's issue of Science. Maine scientists will use the genome to further research in human development and disease. The genome will also provide important biological data that may assist marine biologists in re-establishing the New England urchin population.

- Cancer cures could work for canines and humans
07-12-2007 · EurekAlert!
One of the major issues associated with longer life expectancy in man and his best friend is an increase in the incidence of cancer. Even though they cannot talk, it seems dogs might be able to tell us why and how certain cancers develop. In turn that could lead to better treatments for both canine and human cancer patients.

- Scientists reveal first-ever global map of total human effects on oceans
02-14-2008 · EurekAlert!
More than 40 percent of the world's oceans are heavily affected by human activities, and few if any areas remain untouched, according to the first global-scale study of human influence on marine ecosystems. By overlaying maps of 17 different activities such as fishing, climate change, and pollution, the researchers have produced a composite map of the toll that humans have exacted on the seas.

- The 'MIP-MAP' game: Indian bug is the ancestor of Crohn's disease pathogen
10-02-2007 · EurekAlert!
An Indian team of researchers led by Seyed E. Hasnain of the Institute of Life Sciences, University of Hyderabad, India has found that a seemingly unknown mycobacterial organism Mycobacterium indicus pranii could be the earliest ancestor of the 'generalist' branch of mycobacterial pathogens. The 'generalist' bacteria infect anything from cockroaches to human and are capable of surviving in soil and water as against human adapted 'specialists' such as tubercle and leprosy bacilli.

- Phoenix rising: Scientists resuscitate a 5 million-year-old retrovirus
10-30-2006 · EurekAlert!
A team of scientists has reconstructed the DNA sequence of a 5-million-year-old retrovirus and shown that it is able to produce infectious particles. The retrovirus -- named Phoenix -- is the ancestor of a large family of mobile DNA elements, some of which may play a role in cancer. The study is the first to generate an infectious retrovirus from a mobile element in the human genome. The findings are reported in Genome Research.

- Neuron cell stickiness may hold key to evolution of the human brain
11-02-2006 · EurekAlert!
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees and other vertebrates, researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules.

- Botulism bug has few genome wrinkles
05-23-2007 · EurekAlert!
The genome of the organism that produces the world's most lethal toxin is revealed today. This toxin is the major weapon in the genome of Clostridium botulinum: less than two kg is enough to kill every person on the planet. The results, reported in Genome Research, show that C. botulinum doesn't have subtle tools to evade our human defences or tricky methods of acquiring resistance to antibiotics, but hits its host with a microbial sledgehammer.

- Stressed-out African naked mole-rats may provide clues about human infertility
07-01-2007 · EurekAlert!
Naked mole-rats could shed light on stress-related infertility in humans, the 23rd annual meeting of the European Society of Human Reproduction and Embryology will hear.Dr Chris Faulkes, a senior lecturer at the School of Biological & Chemical Sciences, Queen Mary, University of London, will tell the conference that the African naked mole-rat is at the extreme end of a continuum of socially-induced reproductive suppression among mammals.
