Sleep enforces the temporal sequence in memory

...sode that otherwise might be blurred to a timeless puzzle of experiences. ...

Inflammation may play role in metastasis of prostate cancer

...al Transduction, and colleagues may help solve the puzzle of why it takes so long for cancer to metastasize, as well as what causes it to do so. Furthermore, this new work may lead to development of anti-metastatic therapies. A major hypothesis in cancer research has been that whether the cancer metastis...

UBC researchers reveal dwarf aquatic plants' hidden ancestry

...ia, Davis. "This provides a major piece in the puzzle of flowering-plant origins ?something Charles Darwin once termed an ‘abominable mystery??by revealing that some of the earliest evolutionary branches were more diverse then we once thought." ...

Mutation improves memory, may lead to memory-enhancing pill

...nada. "It's a small, but important part of the big puzzle of how memory works.? "The next step, which is inevitable, is to look for small molecules that mimic this memory-enhancing effect," he continued. "If such a pill could be generated, it might provide a new method for treating people with memory-r...

Rare cell prevents rampant brain activity

...librium. Just how the brain manages this feat is a puzzle to scientists. Scientists at Karolinska Institutet and the Brain Mind Institute in Switzerland have now discovered a mechanism that might explain how the most common type of neuron in the cerebral cortex ?the pyramid cell ?is prevented from becom...

Discovery of new cave millipedes casts light on Arizona cave ecology

... and provide researchers with another piece of the puzzle needed to better understand cave ecosystems. He explained that during the last Ice Age, when northern Arizona was warmer and wetter, millipedes lived in leaf litter. As the climate warmed, they sought refuge in caves, where the subterranean real...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...er the coming decades through global warming, this puzzle piece has become more pressing for plant scientists, who hope that understanding the stress responses of plants will, in time, lead to new generations of plants that are, among other things, more drought- and stress-tolerant. That is why a study th...

Left-right wiring determined by neural communication in the embryonic worm

...rcent of the time. "What makes this an interesting puzzle to solve is understanding how the left and the right side become different from each other, and how they coordinate their activity so that every worm still has exactly one of each type of cell," says the paper's senior author Cori Bargmann, Torsten N...

DOE JGI sets 'gold standard' for metagenomic data analysis

...ate the identity of an organism from the scattered puzzle pieces of DNA. "One of the problems in assembling metagenomes," said Mavrommatis, "is that you end up with large fragments of unknown accuracy and a substantial number of sequences that fail to fit onto those larger fragments. On many occasions,...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...just one of the major pieces to this long-standing puzzle for biologists." "Assimilation of atmospheric CO2 by marine phytoplankton is a global-scale process that is responsible for about half of the biosphere net primary production," said collaborator and co-author Hervé Moreau of the Pierre & Marie...

St. Jude study shows genes play an unexpected role in their own activation

... gene. This finding adds an important piece to the puzzle of how cells use CREB to activate specific genes in response to cAMP signals. It also suggests that the current model scientists use to explain how CREB works is too simple, said Paul Brindle, Ph.D., associate member of the Department of Biochemi...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...r cells have estrogen receptors. As pieces of a puzzle come together, Dr. Song notes scientists already a...se on transplant lists today, another piece of the puzzle is developing techniques for growing organs. In fact, he is collaborating with scientists at Yale Un...
