Scripps scientists find potential for catastrophic shifts in Pacific ecosystems

...sical and biological interactions is going to be," say the researchers. "It appears we will never be able to explain these processes in a clean and simple way." Still, there is room for optimism. The authors believe that "with luck and work we may be able to make modestly accurate statistical forecasts o...

Stem cell research - new cell lines

...al lines they have developed. "It is too early to say anything about these clonal lines, but one of them is inclined towards the cells which form the guts and liver," said Dr Sidhu. Dr Sidhu and Professor Bernie Tuch, the Director of DTU have received a grant for US$140,000 for two years from the Juven...

Gene keeps neural cells on correct developmental path

...s an embryonic stem cell into a mature nerve cell, say Howard Hughes Medical Institute (HHMI) researchers. This new study, published in the May 20, 2005, issue of the journal Cell, may be among the first to track a set of genes from stem cell to differentiated neuron. It also reveals fundamental details...

Mother birds increase progesterone to hatch females

... for the poultry industry, Correa and Adkins-Regan say that understanding the basic mechanism of biasing sex ratios in birds could provide the foundation for learning how to manipulate the sex ratio of avian offspring in the future. Research in this area is just beginning, they note, because the molecula...

Cousin of Asian super termite invades Florida

...more than 70 miles north of Miami. The researchers say they're not sure how much farther north the tropical species can move and survive. "Four buildings in a one-square-mile area of Riviera Beach are infested with the termite, and we believe there may be more infestations in the area," Su said. "We are...

15-year hunt finds cause of pseudothalidomide syndrome

...health and disease beyond the rare disease itself, say the researchers. Because of advances in technology and computer analysis, the researchers were able to find the Roberts gene, called ESCO2, by studying samples from just 15 Roberts syndrome families from Colombia, Turkey, Canada and Italy and to pro...

Future diabetes drugs may target new protein interaction

PGC1, which Puigserver isolated and cloned in 1998 as a postdoctoral fellow at Harvard, controls gene expression in the liver and other tissues. In the liver, it triggers the conversion of fats into sugar, particularly whe...

The authors say that their results will provide a basis for developing new molecular diagnostic techniques and, eventually, targeted therapies for patients with skin cancer. PNAS is the multi-disciplinary, peer-reviewed journal of the National Academy of Sciences. ...

Nanobacteria in clouds could spread disease, scientists claim

...ra Wickramasinghe of Cardiff University, UK. They say nanobacteria are now accepted as being widely prevalent in the terrestrial environment and that their evidence is compelling for the existence of these nano-organisms, even in the stratosphere. In humans, nanobacteria have now been identified on four...

Active Vaccine Prevents Mice From Developing Prion Disease

... was conducted in normal mice, the NYU researchers say it will be easier to apply in animals in the wild, which are at risk for developing prion disease. Prion disease is contracted when an animal eats the body parts of other animals contaminated with prions. What makes these infectious particles unusua...
