Growth in the sea comes down to a struggle for iron

...ent into the Pacific, it may be that phytoplankton closer to the source of that dust may be primed to respond differently. Wells and his colleagues will be studying the possibility that small variations in iron throughout the world's oceans may have important ecological consequences as well. Their results ...

Dinosaur DNA? New Patent Covers Degraded DNA recovery

...when properly applied by our scientists, brings us closer to our goal of reconstructing genetic history. We now have the picture on the outside of the puzzle box, and by stringing together the pieces of aged DNA, we should be able to reconstruct genes from animals such as the wooly mammoth, giant sloth, sab...

Nano-Probes Allow an Inside Look at Cell Nuclei

...y, Chen and Gerion wondered if they could get even closer to the genetic action by transporting quantum dots inside cell nuclei. "We took the tool Paul developed and applied it to a problem faced by biologists every day ?getting inside the nucleus, a desirable target because the cell's genetic information ...

New studies suggest airborne SARS transmission is possible

...peculate that the increased risk of infection with closer proximity to the index SARS case suggests airborne transmission. Although they do not have "direct proof" of airborne transmission, according to Dr. Yu, "no other known routes of infectious diseases transmission could adequately explain the spread of...

NJIT Presidential Award winner takes stem cell research another step

...ringing the promise of stem cell research one step closer to reality. Arinzeh, PhD, assistant professor of biomedical engineering at NJIT, is researching the use of stem cells to induce bone repair. Her research will help diabetics whose impaired bones will not properly heal. She is using adult stem cells,...

LUCA technologies confirms real-time methane generation

...when the hydrocarbon deposits were less mature and closer to the surface of the earth. Luca scientists, employing the tools of modern biotechnology and genomics, have now shown that living methane generating, microbial consortia are present and actively forming methane within some of these hydrocarbon subs...

New lab technique identifies high levels of pathogens in therapy pool

...n a Midwest therapy pool, pointing to the need for closer scrutiny of public hot pools, says a new study. Led by Washington University in St. Louis and involving the University of Colorado at Boulder and San Diego State University, the new study assessed the microbe population in a warm hospital therapy po...

Birds brains reveal source of songs

...e for Brain Research at MIT now have come one step closer to understanding that process. They've shown for the first time how a particular brain region in birds serves as the source of vocal creativity. "It's an extraordinary finding," says Sarah Bottjer of the University of Southern California. "Here's an...

Chemicals in tattoo inks need closer scrutiny

...e world's largest scientific society, suggest that closer regulation of the tattoo industry may be warranted, according to the researchers. Although inks used in tattoos are subject to regulation by the U.S. Food and Drug Administration as cosmetics and color additives, the agency has not traditionally reg...

FDA Works To Speed The Advent Of New, More Effective Personalized Medicines

"This new technology will allow medicines to be uniquely crafted to maximize their therapeutic benefits and minimize their potentia...

The evolutionary triumph of flower power

...ner with recipients smiling, chatting and standing closer together. In the last study, florists delivered bouquets to 113 men and women in a retirement community ?an environment in which memory is often a personal concern. All 113 got flowers, some at the beginning of the study with a follow-up bouquet a f...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

... is what we're trying to understand. We're getting closer to answering this question." The structure reveals a "pseudoknot" that is required for telomerase activity, at whose core three strands of RNA come together to form a triple helix. All vertebrate animals investigated so far have nearly the identical...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

...tly into the brain. "The brain of the cat is much closer in size to the human infant brain compared to mice. Thus we think that it may be possible to achieve similar results in humans with as few as 20 to 30 injections in each of the two hemispheres of the brain," Wolfe said. "We believe, however, we can f...

Cellular Defects in Premature Aging Disease are Reversible

...nline on March 6, 2005, brings scientists one step closer to understanding this devastating childhood disease and might provide insights into the normal aging process. HGPS is a rare inherited disease affecting about one in eight million children. While appearing normal at birth, infants with HGPS age rapi...

The circadian clock: Understanding nature's timepiece

... the University of Calgary is getting a little bit closer to understanding how it ticks. Dr. Michael Antle, a neuroscientist in the U of C's Department of Psychology, has conclusively shown that the 20,000 cells are organized in a complex network of groups that perform different functions ?contrary to the ...

Stem cell research - new cell lines

...olony from a single cell, researchers are one step closer to deriving a homogenous population of cells of a particular type. "There are about 230 different cell types in the body. All these cells are derived from three embryonic layers ?one which forms the brain and spinal cord, another which forms the gut...

Discovery clarifies role of peptide in biological clock

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...d by our findings. This progress moves us one step closer to drugs that work by switching telomerase on permanently and keeping the immune cells young and strong in their fight against infection," said Effros. "These therapies are also easier to develop than gene-therapy drugs." The research was supported ...

Scientists generate patient-specific stem cells, Science study says

...aboratory. The work also moves scientists one step closer to the goal of transplanting healthy cells into humans to replace cells damaged by diseases such as Parkinson's and diabetes. Each of the 11 new human embryonic stem cell lines was created by transferring the nuclear genetic material from a non-repr...
