Clues to breast cancer hidden inside stem cells

...erkeley National Laboratory in California. "We can build up a 3-D breast structure similar to what you have in vivo," says Gudjonsson. "You can analyse cell-cell interactions and signaling pathways in these cells during morphogenesis and in cancer progression." The Icelandic researchers are now focusing ...

Warbling whales speak a language all their own

...les have their own syntax that uses sound units to build phrases that can be combined to form songs that last for hours. Until now, only humans have demonstrated the ability to use such a hierarchical structure of communication. The research, published online in the March 2006 issue of the Journal of the ...

Clock molecule's sensitivity to lithium sheds light on bipolar disorder

...reset clocks that become stuck when Rev-erb levels build up." These results point to Rev-erb as a lithium-sensitive component of the human clock and therefore a possible target for developing new circadian-disorder drugs. Some patients taking lithium have developed kidney toxicity and other problems. Laz...

Lactic acid not athlete's poison, but an energy source - if you know how to use it

...ps people get rid of the lactic acid before it can build to the point where it causes muscle fatigue, and at the cellular level, Brooks said, training means growing the mitochondria in muscle cells. The mitochondria - often called the powerhouse of the cell - is where lactate is burned for energy. "The wo...

NJIT engineer poised to take stem cell research a step forward

...ds spinal cord research. She will use the grant to build a laboratory to test if stem cells taken from adult bone marrow can be made to turn into neurons. If her research shows that the cells can turn into neurons -- the nerve cells in the body that control brain and spinal cord function -- patients with s...

Butterflies lose body fat during metamorphosis

... beings are much in the same category." Hoping to build on these initial findings, Connor and his colleagues are planning on looking at the Monarch butterfly next. Monarch larva feed exclusively on milkweed, and Connor has already started growing milkweed and analyzing it for this purpose. "It has very ...

Honeybee decision-making ability rivals any department committee

...nt signals in relation to site quality, the scouts build up most rapidly at the best site. As soon as 15 or more bees are at any one site, the researchers found, the scouts signal to the waiting bees in the swarm that it's time to warm up their flight muscles in preparation for takeoff. Each scout does s...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

Wisconsin scientists find a way to make human collagen in the lab

...hin extended fibers," says Raines. "We are able to build these molecules up one atom at a time and we can manipulate them in very precise ways." The new Wisconsin study, which was supported by grants from the National Institutes of Health, lays a foundation for bringing human collagen to the clinic, says ...

Illinois pig to make history as source of first complete swine genome

...ence in each piece," Schook said. "We were able to build a map to know what parts of the pig genome were equivalent to the same parts of the human genome. Now we can take those parts and compare them sequence by sequence." Schook, Beever and Bruce Schatz, interim head of the department of medical informat...

Genomics-based vaccine could prevent deadly cattle disease

...irst to take advantage of genomic technologies and build a test vaccine using immune killer T cells as a screening reagent." In addition to TIGR and ILRI, the research team included scientists from: the Ludwig Institute for Cancer Research in Brussels; the Wellcome Trust Center for Human Genetics in Oxford...

NHGRI announces new sequencing targets

...twork "The goal of our sequencing program is to build the most powerful toolbox possible for advancing human health. By identifying and seeking to fill crucial gaps in our knowledge, these new sequencing plans represent yet another important step in that direction," said NHGRI Director Francis S. Collin...

Basic research leads to a novel cancer therapy

...l, this can cause the cell to propagate itself and build certain tissue similar to blood vessels. Worldwide, research into receptors has focused on a special class of proteins, called tyrosine kinases. They are responsible for causing the received signal to be transduced through a long signalling cascade i...

Penguins waddle but they don't fall down, UH researchers say

...en they walk and run. His research can be used to build smaller computers for such robots that will become increasingly more life-like. "There is not much research on this issue, so we're hopeful about the results," Kurz said. To facilitate his study, Kurz has created a special platform that contains...

Unraveling the mysteries of poison

...ly certain ions through the membrane. The channels build an electro-chemical gradient, allowing nerve and heart muscle cell signals to pass. The nerve or heart muscle cell is excited, and the ion channel structure changes, developing pores which let the ions through. Different channels are open to differen...

Insects and mammals share common fat-building pathway, study suggests

...t formation is blocked, lipid deposits may instead build in other parts of the body, such as muscle or liver. "The 'problem' in obesity is energy balance that is out of whack, and not a surfeit of adipocytes (fat cells) per se." Regardless of the study's therapeutic implications, the findings will nonethe...

UF scientists trace origin of shark's electric sense
