Chemists create 'Superbowl' molecule; May lead to better health

...things to pass in and out. This is ideal if you're trying to capture certain molecules and hold them until they're ready for release, the researcher says. Superbowl molecules are similar in function to buckyballs, the experimental soccer-ball shaped molecules also known as fullerenes (C60), which also show...

Wisconsin scientists grow critical nerve cells

...se they provide critical guideposts for scientists trying to repair damaged or diseased nervous systems. Motor neurons transmit messages from the brain and spinal cord, dictating almost every movement in the body from the wiggling of a toe to the rolling of an eyeball. The new development could one day he...

UAB scientists discover the origin of a mysterious physical force

Ever since the 1970s, scientists have been trying to establish the cause of a repulsive force occurring between different electrostatically charged molecules, such as DNA and other biomolecules, when they are very close to each other in aqueous media. This force became know as hydration force. Jord...

Growth in the sea comes down to a struggle for iron

...sically chemical warfare by the bacteria in soils, trying to get the iron. They specifically target iron with these molecules. Siderophores don't complex other metals very well. The idea is that it (the molecule) is like a magic bullet. They release it, it binds iron, and then only they have the key to unlo...

Mouse brain cells rapidly recover after Alzheimer's plaques are cleared

...rendza wondering if the nerve cells are constantly trying torestore their normal structure. If so, that recuperative effort mustsomehow be countered on an ongoing basis by the effects of the plaques.More research is needed to determine if similar effects will occur inhumans. Abeta antibodies are currently b...

Gene therapy converts dead bone graft to new, living tissue

...The Musculoskeletal Transplant Foundation has been trying for two decades to conquer the issues complicating bone transplants, and the group has pledged to continue supporting Schwarz's research. Schwarz hopes to begin early human trials with the procedure soon. "This technology looks like it will have a d...

Enzyme shown to help protect genomic stability

...as they move beyond sequencing the human genome to trying to better understand how DNA is managed and its activity regulated. Histones are small proteins around which DNA is coiled to create structures called nucleosomes. Compact strings of nucleosomes, then, form into chromatin, the substructure of chromos...

BRCA1 causes ovarian cancer through indirect, biochemical route

...s actually good news for scientists and physicians trying to figure out new ways to treat ovarian cancer. If the cancer had arisen in the same cells that had the BRCA1 mutation, the only way to interfere would be to correct the mutation. In this case, however, there's a mediator-a biochemical of some sort-t...

Poplar trees redirect resources in response to simulated attack

... vital plant processes." Ferrieri says scientists trying to improve plants' resistance to environmental challenges -- or their ability to perform useful tasks such as carbon sequestration, phytoremediation, or the production of bio-fuels -- could also use functional imaging to help track their progress. I...

Purdue proves concept of using nano-materials for drug discovery

... Engineers and scientists in the Purdue center are trying to find drugs that deactivate the pumps, which would make the chemotherapy drugs more effective. The researchers are developing synthetic cell membranes to mimic the real thing and then plan to use those membranes to create chips containing up to 1 m...

Researchers identify target for cancer drugs

For nearly a decade, scientists have been trying to fully understand a particular communication pathway inside of cells that contributes to many malignant brain and prostate cancers. While scientists have identified elements of this pathway, other key components have remained a mystery. Researchers...

Scientists rid stem cell culture of key animal cells

... in the human body and, in culture, are constantly trying to migrate down different developmental pathways. Maintaining stock cultures in their undifferentiated state is critical. The feeder cell dogma now can be overturned, says lead investigator Ren-He Xu, a senior scientist at WiCell, a private, nonprof...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

... runs quite fast, and in this latest study we were trying to figure out what those speed limits are, especially with regard to varying amounts of clathrin," Dr. Ryan explained. However, they faced one methodological roadblock. As Dr. Ryan explained, scientists have long known how to gauge the importance o...

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...ving these analogues into clinical trials. "We're trying right now to get a company interested in this, especially because the mice used in our trial seemed to experience minimal toxicity -- a good sign that patients might tolerate these compounds, too," Dr. Huang said. "It's all very exciting," he said. ...

Taking Aim With Nanoparticle PEBBLEs

... plan to tinker with the PEBBLEs a bit more before trying them on larger numbers of rats, and PEBBLE-based cancer treatments for people are a long way off. But "there's no doubt," said Kopelman, "that nanoparticles such as PEBBLEs can do a fantastic job for therapy, diagnostics and a combination of the two....

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

...get through the vegetation. It was exhausting just trying to get around on those islands," he said. The researchers found that the density of breeding seabirds on fox-free islands was two orders of magnitude higher than on fox-infested islands. The resulting difference in nutrient inputs was reflected in s...

Development of portable infectious disease detector

...ping theirsystem as simple as possible. Instead of trying to squeeze everythingonto a single chip, Pria designers started with a desktop diagnosticsystem and shrank it down into a device about the size of a coffee cup.One of the cost-saving aspects of the design was to keep thefluid-handling components sepa...
