Study shows isolation of stem cells may lead to a treatment for hearing loss

...ase Western Reserve University School of Medicine, recently published research findings in Developmental Neuroscience which suggest new ways of treating hearing loss. These researchers have isolated “cochlear stem cells?located in the inner ear and already primed for development into ear-related tissue due t...

Researchers design pulsed mircrojet system to deliver protein drugs without pain or bruising

...ell booster. Needle-free delivery of vaccines has recently been identified as one of the significant emerging challenges in global health. The researchers felt that the pain and bruising caused by previously-developed jet injectors was caused by the deep penetration of jets into the skin, creating negativ...

Mine runoff continues to provide clues to microbial diversification

...nd at Richmond Mine near Redding, Calif., combines recently developed ways to sequence microbial genes with methods to identify the range of proteins from specific microbial members. Researchers from Oak Ridge National Laboratory and UC Berkeley discovered that Leptosprillium group II bacteria in these str...

Nanotextured implant materials: blending in, not fighting back

...to combat this problem, but concerns have surfaced recently about increased clotting. Instead of using chemistry to fight the body's response to such foreign materials, Thomas Webster, an associate professor of engineering, and Karen Haberstroh, an assistant professor of engineering, thought maybe they cou...

OHSU surgeon implants donated tissue allografts

...lready proven valuable. Several OHSU patients have recently benefited directly from the increased availability of fresh tissue for transplantation performed for complex joint cartilage restoration procedures. Patients diagnosed with osteochondral injury, or cartilage injury can ask their physicians about ...

Male reindeer inflate a large air sac in the neck region to emit their hoarse rutting calls

...ductive success. The results of this research have recently been published in Journal of Anatomy. As in other species with harem-like mating systems, the voice organs of reindeer differ according to gender. Adult males have a much larger air sac than females and the young. In early life, growth of the air...

Remote sheep population resists genetic drift

...ance, have published the results of their research recently in the journal Proceedings: Biological Sciences. Haute Island sits in the Kerguelen Archipelago in the southern Indian Ocean and is more than 3,000 kilometres from its nearest port. The French government has used the island as a military outpost ...

When your brain talks, your muscles don't always listen

...nce Laboratory at the University of Massachusetts, recently published the results of a study on motor-unit firing rates in the Journal of Applied Physiology, and Knight is now beginning a new project focusing on motor-control mechanisms in the elderly. Both studies are sponsored by the National Institutes of ...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

..., sawdust, straw and grain hulls. A UWM professor recently helped DOE do just that by analyzing the DNA of a ... the perimeter of the cell. These filaments were recently imaged in collaboration with Sriram Subramaniam and Jun Liu at the National Institutes of Health by ...

Gene elevating breast cancer risk also causes prostate cancer

...results of this international research effort were recently published in Nature. The research first involved comprehensive screening for genetic aberrations in 113 Finnish breast cancer families. The same constitutional mutation in PALB2 was observed in three families. It was later showed that the relevant...

New sucker-footed bat discovered in Madagascar

...n forests of Madagascar, according to new research recently published online in the journal Mammalian Biology. The new species is obviously different from the known species based on pelage coloration, external measurements and cranial characteristics, according to the researchers. Myzopoda are often found in...

Microbes start immune response by sneaking inside cells

...owing body of research revealing the importance of recently discovered receptors such as cryopyrin inside cells, known collectively as NOD-like receptors. Knowledge about NOD-like receptors is moving forward rapidly and will contribute to a fuller understanding of the human immune system, say the U-M research...

Childhood obesity among Quebec Cree raises concerns

...ns, Inuit and Métis children. In a study published recently in the American Journal of Public Health, University of Alberta researchers found that up to 65 per cent of Cree preschoolers in northern Quebec communities were overweight or obese. Dr. Noreen Willows, a community nutritionist at the University of ...

Iowa State University botanists identify new species of North American bamboo

...ndinaria appalachiana. Clark, Triplett and Weakley recently completed the intricate process botanists are obliged to follow to officially name and describe a newfound species. Following rules laid out in the International Code of Botanical Nomenclature, they prepared a short description of the plant in Latin ...

Destructive enzyme shows a benevolent side

Phthalates now linked to fat, related health risks

... been widely used for more than 50 years, but only recently implicated as a possible health risk in people. Animal studies have shown consistently that phthalates depress testosterone levels. Recent human studies have found that phthalates are associated with poor semen quality in men and subtle changes in th...

New molecular pathway could reveal how cells stick together

...published these findings earlier this year and was recently awarded an individual investigator research grant to extend her work from cells in a Petri dish to an organism. The grant, from the National Institute of General Medical Sciences, is for $ 1.4 million over five years. "We're trying to figure out h...

Instruction manual for creating a molecular nose

...earch and the Max Planck Institute of Biochemistry recently revealed a technique for integrating membrane proteins into artificial structures. Membrane proteins have several important functions in the cell, one of which is to act as receptors, passing on signals from molecules in the air, for example, to the ...

Bioluminescence at the service of a novel cerebral imaging technique

... the study of ageing and longevity, because it has recently been shown that flies endowed with a mutation of the insulin receptor live much longer. It is also possible to exploit the powerful genetic tools of the Drosphila to study and compare these maps in flies bearing different mutations, or in flies whic...

World's largest flower evolved from family of much tinier blooms

...esh, and in some cases even emit heat, much like a recently killed animal. These traits help the flower attract the carrion flies that pollinate it. "While it's surprising to find this giant plant evolved from a family typified by much smaller blossoms, rafflesia is unusual enough that it's frankly been dif...
