Researchers from the University of Navarra analyze new kinds of cancer-fighting antibodies

...s in treatment combinations are as positive as the results on test animals predict. Aside from this, there are another four members of this monoclonal antibiotic family, which stimulate the immune system, currently being developed. Their use in patients began a year and a half ago, and to date no conclusi...

Aspirin discovery may improve cancer treatments

... showed that treating human cells with salicylates results in the phosphorylation of the translation initiation factor eIF2Ą, thus inhibiting protein synthesis," Professor Williams said. "Inhibiting or slowing down protein synthesis reduces the accumulation of incorrectly folded proteins in cells, which ...

Major gene study uncovers secrets of leukemia

...n the March 7 online edition of "Nature." "The results of our study demonstrate that it is possible to significantly speed the identification of the genetic lesions that are the underlying cause of not only ALL, but also many other cancers, including those affecting adults," said James Downing, M.D., sci...

Researchers learn what sparks plant growth

...e shoot for steroid hormones is the epidermis. Our results also show that these hormones act locally. As similar studies are done for other plant hormones and in other organs, such as the root, we will know the major sites of action of each plant hormone and will be able to make models to predict how they wo...

Human's ecological footprint in 2015 and Amazonia revealed

...at the nation-state level. They then utilize their results to project future levels of stressors. Restricting their data to countries of at least one million people, Dietz and colleagues calculated basic forms of consumption, including crops, meat, energy, and living space, using data from the World Wide...

Individual differences in a clock gene predict decline of performance during sleep deprivation

...hers experienced no problems with the task. The results were most pronounced during the early hours of the morning (between 4 and 8 a.m.), during which individuals with the longer variant of the gene performed very poorly on tests for attention and working memory. The authors point out that this early-...

Tracking sperm whales and jumbo squid

...13 dives (3 percent) exceeded 3,200 feet. These results closely mirrored the diving data collected from the squid. "Tagged squid in our study occupied the 100-500 meter [300 to 1,600-foot] zone, the same region to which the whales dove over 90 percent of the time, consistent with the idea that whales were...
