The secret lives of whales

...umbi. “Ice ages, sea level change and even loss of local food sources did not interrupt their lives. Living in a fluid environment they could move to new areas of productivity and find food even as the climate around them changed.?/p> Palumbi compares the ability to read genes to counting the rings of ...

Essential mangrove forest threatened by cryptic ecological degradation

... ecologically and socio-economically important for local people in tropical countries on all continents. Using biology, geography, hydrology, socio-economic interviews, and 18th-century history, an international team led by Dr. Farid Dahdouh-Guebas has demonstrated that in the recent past an increase in hu...

U-M scientists find genes that control growth of common skin cancer

Same mutation aided evolution in many fish species, Stanford study finds

...reshwater sticklebacks they studied, including one local species the group collected from a stream near Fresno. Perhaps mutations in the two other genes cause problems for the fish in addition to reducing the number of armor plates, Kingsley said. Most of these fish evolved independently from marine ances...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

... transcription factors, but may also influence the local topology of the DNA, thereby controlling access to their associated gene. Several clusters also appear in regions without any known genes—the identification of these clusters might lead to the discovery of new developmentally significant genes. Whil...

Unprecedented water level rise in Somalia

...here by over two meters in 15 hours. It was by all local accounts unprecedented in recent times and indicated that a major surge of water was now passing into Central Somalia. Heavy rain was also expected to continue into next week. In Jowhar, 90 kilometres north of the capital Mogadishu, three villages w...

Genrate: a generative model that finds and scores new genes and exons in genomic microarray data

...nd false-negative rates. The model has a number of local minima that is exponential in the length of the DNA sequence data, so direct application of the EM learning algorithm produces poor results. We describe a novel way of parameterizing the model using examples from the data set, so that good solutions ...

Expression Project for Oncology (expO) completes first phase of standardized gene expression analyses

Scientists then conducted a track survey, in which they attempted to find evidence of the animals in a specific area. This information was used to determine where to set up camera traps, armed with infrared sensors trigger...
