Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

...nning of the 1970's. A similar trend is found for deeper waters of the Straits, for Indonesian fisheries in the Java Sea, and indeed for most coastal fisheries of South East Asia. WorldFish says governments have recognized that the fishing capacity being rebuilt post-tsunami "should be commensurate with ...

Neurons find their place in the developing nervous system with the help of a sticky molecule

...ining the interfering RNA were stalled in aberrant deeper locations, indicating that loss of MDGA1 protein had stymied their attempt to travel the full distance to layer 2/3 and supporting the original hypothesis. The goal now is to determine how MDGA1 controls neuronal migration and what the long-term cons...

Oceans are 70 percent shark free

... oceans and it had been hoped that as man explores deeper into the abyss and beyond throughout the largest environment on the planet - new species would be discovered. However, 20 years of exploration, combined with analysis of records over the past 150 years, has convinced the team of scientists that t...

The closest look ever at the cell's machines

...s us from the level of the entire cell to the much deeper level of all the molecules and atoms that make it up." Baker's yeast is evolutionary related to the cells of animals and humans, which means that the findings will be more widely applicable. "The same principles discovered here in yeast apply to hu...

Research details how a virus hijacks cell signals to cause infection

...h the CAR. A second signal leads the virus to move deeper into cells where it can release its nucleic acid payload and complete the process of infection. "We showed for the first time that this virus is dependent on signaling pathways to drive invasion," said Dr. Bergelson. Specifically, the coxsackieviru...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...at this public/private initiative will encourage a deeper collective understanding of the genetic factors of disease for major new therapeutic advances." GAIN will be an FNIH-managed partnership that includes NIH, industry, foundations, individuals and advocacy groups. Governance will include an executive ...

Parachuting allows krill to eat and run

Scientists discover new genetic subtypes of common blood cancer

...ict how aggressive the disease would be. For this deeper analysis, the researchers created an algorithm based on a recently developed computational method designed to recognize individuals by facial features. It is called non-negative matrix factorization, or NMF. In the myeloma study, the algorithm was us...

Study reveals how ADHD drugs work in brain

...e future, Berridge and his colleagues plan to look deeper within the PFC to gain more detailed insights into how ADHD meds act on nerves to enhance cognitive ability. Other researchers who contributed to the study include UW-Madison co-authors David Devilbiss, Matthew Andrzejewski, Ann Kelley, Brooke Schme...

Fish virus in Northeast spreading to other fish species

... and heavy winds may have washed up more fish from deeper waters. Groocock added that while more species of fish are dying, absolute numbers of fish mortalities do not appear to be changing. "There is no cure for VHSV in fish in an ecosystem as large as the Great Lakes Basin. Given this, it is likely that ...

A dichotomy in migration patterns found for sea turtles in east Atlantic

Interestingly, while adults compose both groups, the coastal feeding strategy correlates with larger animal size. These new findings revise our understanding of the turtle's ...

Links between DNA damage and breast cancer studied

... that develop into cancer may occur initially in a deeper layer of breast tissue, called the stroma. Genetic changes in this connective tissue that supports the breast's network of glands and ducts have been reported to precede the malignant conversion of tumor cells, but the actual role of stromal cells in...

Choosy females make colourful males

...hese differences evolve? The red species occurs in deeper water than the blue species and therefore experiences different light conditions. Behavioural experiments showed that both species have adapted to this: the red species is more sensitive to red light and the blue species is more sensitive to blue lig...

Massive duplication of genes may solve Darwin's 'abominable mystery' about flowering plants

What controls stickiness of 'smart' chromosomal glue

...ore they can be released. According to Amon, a deeper basic knowledge of the mechanism of cohesin loss during meiosis could ultimately improve understanding of the origins of miscarriages and mental retardation due to mis-segregation of chromosomes. "We first need to understand the key regulatory play...

Ryan, a motivational psychologist at the University and lead investigator in the four new studies about gaming. Players reported feeling best when the games produced positive experiences and challenges...

New biochip helps study living cells, may speed drug development

...ces of data. This additional data allows for a deeper understanding of cellular activity compared to current technology, which measures only one point outside one cell and cannot record simultaneously, Porterfield said. The chip also directly records ion concentrations without harming the cells, whereas...
