First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands

...s monk seals, or colorful aquarium fish (until you look under a microscope), they form the complex tapestry that supports the existence of the larger animals, and changes in their abundance or diversity are often the first indicators of environmental impacts or changes. These groups of organisms are also ...

Proteins may behave differently in natural environments

...native GroEL, the finding may indicate the need to look at the chaperone itself more closely. "The expansion was directly related to the function of the assembly. From a more global perspective, this is strong evidence that we need to study how any macromolecule behaves in a solution environment." ...

Taking 'chips' to the next level of gene hunting

...of the picture of mutations in humans because they look only at the meaty parts of genes, but the human ge... hopes that the TIP-chip eventually can be used to look for such mutations in people. The new TIP-chip contains evenly sized fragments of the yeast geno...

Inheritance outside DNA

...netics of cancer. Now Feinberg has taken a new look at genomic imprinting, as a cancer-predisposing factor. Feinberg analyzed a common epigenetic alteration—found in 5?0 percent of the general population—that involves the loss of imprinting on an insulin-like growth factor gene called IGF2. Loss of im...

Evolution and the workaround

... both sturdy and flexible. The Stowers researchers look to these evolved yeast strains for future explanations of how the duplication of genetic information contributes to the robustness and adaptability of all living things. ...

Distinguishing friend from foe in the battle against cancer

... sent by mutant proteins in cancer cells. STIs may look like overnight successes, but they are actually the result of decades of hard work. "We have been working for 35 years looking at mechanisms underlying formation of cancer cells," says Hunter, an American Cancer Society professor in the Molecular a...

First biomarker for human sleepiness identified in fruit flies

... identify a marker for sleep debt, Shaw decided to look in saliva. Easily accessible, saliva contains many...kinds of sleep deprivation and used microarrays to look for changes in activity in many different genes. Amylase levels consistently changed after sleep los...

Nanoparticle assembly enters the fast lane

... National Synchrotron Light Source. The scientists look to further improve the controllability of the system, focusing next on the size of the nanoparticle clusters. ...

Mutant mouse provides insights into breast cancer

.... "It's known that most cancers, by the time you look at them, have genomic instability in some form or another," said John Schimenti, a genetics professor in Cornell's Departments of Biomedical Sciences, and Molecular Biology and Genetics and the paper's senior author. "Our research demonstrated that g...

Shrinking ponds signal warmer, dryer Alaska

...curacy goes down," Riordan said. Cloud shadows can look like water and Alaska rarely experiences a cloudless day, said Verbyla. The most difficult part of the four-year project, said Riordan, was "having the patience to circle 10,000 ponds for each time period." The main study area was the subarctic ...

LSU professor discovers new species

...ethods for finding lizards in the rainforest is to look under logs. We found two individuals of the new species under one log and two more under another." With more than 15 years of fieldwork experience behind him, Austin knew immediately that he had found a new species. After collecting the lizards, he a...

Successful lung cancer surgery not enough to break nicotine dependence in many smokers

...ology Biomarkers & Prevention, is the first to look at smoking relapse among people who were "forced" to quit due to impending surgery. "These patients are all addicted, so you cannot assume they will easily change their behavior simply because they have dodged this particular bullet," said the stu...

High-throughput oncogene mutation detection in human cancers by mass spectrometry-based genotyping

Climate experts search for answers in the oceans

...Because we now have detailed data that allow us to look for correlations, we are learning how to read those messages," said Prof. Ian Robinson at the National Oceanography Centre, Southampton (NOCS) and Medspiration Project Manager. "ESA is making a difference to public awareness of climate change by help...

Hope for major advance in fighting world killer disease

...essor Williams commented: "All cases of diarrhoea look the same to start with, and children are usually given oral rehydration therapy, which is cheap and puts back fluids lost by diarrhoea. But disease caused by EPEC and Shigella does not usually respond to oral rehydration therapy. They are much more ...

Poor athletic performance linked to vitamin deficiency

...here's a lot of pressure on women in particular to look like an 'athlete.' Unfortunately for some people that means skinny and petite, rather than healthy and strong." The B-vitamins are in whole and enriched grains, dark green vegetables, nuts, and many animal and dairy products. Manore suggests athlet...

Chemical tests of cell growth enter third dimension

...uch the cells are growing. Fluorescing cells don't look very bright in the well, because they grow as a thin film layer that is essentially two-dimensional. Researchers get around this problem by removing the cells from the well and counting them one by one under a microscope. It's a long and tedious pro...

Brain regions do not communicate efficiently in adults with autism

A novel look at the brains of adults with autism has provided new evidence that various brain regions of people with the developmental disorder may not communicate with each other as efficiently as they do in other people. Researchers from the University of Wash...

Quantum dots reviewed -- Could these nanoparticles hold the cure to cancer?

...f breast cancer. The paper concludes with a quick look at what the future may hold for Quantum Dots in providing new insights into understanding the pathophysiology of cancer and real time imaging and screening of tumours. The level of details provided in this valuable review paper could easily make ...
