St. Jude study solves mystery of mammalian ears

... how the body works, and then use those answers to solve medical problems in the future.” The long-standing argument centers around outer hair cells, which are rod-shaped cells that respond to sound waves. Located in the fluid-filled part of the inner ear called the cochlea, these outer hair cells sport ...

Students invent protective pouch to enhance cell therapy

... he and his team members appreciated the chance to solve a real-world engineering challenge while drawing on the expertise of prominent researchers such as Arepally and Bulte. "I don’t think I could have found an opportunity like this anywhere else," he said. "That’s one of the major strengths of Johns Hop...

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

...he 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. Wiesel ...

Man's best friend lends insight into human evolution

... According to Hare, domesticated dogs' ability to solve social problems may have emerged once the brain systems mediating fear were altered ?and the same thing may have occurred in human evolution. Chimps, he says, are constrained in solving cooperative problems by their impulse to fear more dominant indi...

UC Davis researchers use heated nanoprobes to destroy breast cancer cells in mice

...entists from Triton BioSystems in Boston, seeks to solve this problem. The experimental system uses bioprobes created by wedding magnetized iron-oxide nanospheres to radiolabeled monoclonal antibodies. The bioprobes are cloaked in polymers and sugars that render them nearly invisible to the body's immun...

Scientists identify molecular cause for one form of deafness

...n Radiation Laboratory, allowed the researchers to solve the structure of various espin-actin bundles. "As the ability of espin to cross-link F-actin is decreased by using genetically modified 'deafness' mutants with progressively more damaged actin binding sites, the structure changes from a well-ordere...

Bacterial walls come tumbling down

...years for vancomycin. Researchers attempting to solve the structure of this enzyme have struggled to recreate its cellular environment in the laboratory. But after much tinkering with different combinations of detergent, ions, and chemical additives, Strynadka's team was able to crystallize the enzyme s...

Elucidation of the genome for diabetics with DNA chips

...ition to vascular complications of diabetes and to solve the mysteries shrouding childhood obesity and certain cancers linked to obesity . The work of this French-British-Canadian team was financed principally by the Canadian government and by the province of Quebec. The DNA chips were produced at the geno...

Protein discovery targets antibiotic-resistant bacteria

...w drug development. “Our group is the first to solve the structure and to begin to understand the function of this particular protein,?says Dr. Nancy Martin (Microbiology & Immunology), who coordinated the study with Dr. Zongchao Jia (Biochemistry). “It turns out to be a potentially good target in ...

Inflammation may play role in metastasis of prostate cancer

...n and Signal 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 canc...

Can engineered immune cells stop AIDS?

...iciency syndrome (HIV). But scientists have yet to solve a vexing problem: developing an efficient transport system that is capable of delivering therapeutic payloads to specific cells. As challenging as the problem has been, researchers in the USC Viterbi School of Engineering may be turning a corner. ...

Ultrasound upgrade produces images that work like 3-D movies

...ewing a single, flat image. Stereoscopic images solve that problem by taking two "snapshots" of the same object from slightly different angles, mimicking the normal difference between left and right eye views. Special glasses or goggles can then be used to fuse the two images into one, gaining a 3-D ...

Scientists produce neurons from human skin

...research. "Producing neurons from skin cells could solve the problem of human neural cell availability for research," explains Berthod. "Since neurons do not multiply, researchers now have to rely on laboratory animal neurons to perform their experiments." In the longer term, the ability to produce neur...

Magnetic system could be key to surgery without scars

...mally Invasive Surgery. He said the technology may solve the fundamental problem of guiding instruments through the abdomen for natural orifice surgery, which now inserts the instruments through the throat, colon or vagina. “The current state of the art for laparoscopic surgery requires four or five hol...

Ring-around-the-cell

...e demolition site. How does this ring form? To solve the mystery, Prof. Benjamin Geiger, Dean of Biology, and Prof. Lia Addadi of the Structural Biology Department, together with doctoral students Chen Luxenburg and Dafna Geblinger, and with the assistance of Dr. Eugenia Klein (electron microscopy unit...

Researcher examines polymers created with poultry feathers

...ers may add value to the poultry industry and help solve the growing environmental problem of plastic waste. According to the U.S. Environmental Protection Agency, more than 29 million tons of non-biodegradable plastic waste ends up in landfills each year. Justin Barone, associate professor of biological ...

MIT device draws cells close -- but not too close -- together

...l. Bhatia and Hui's first thoughts about how to solve this cellular space and time problem involved another children's game: plastic puzzles with squares that slide around on a grid. They wondered if they could put different cells on each square and then move them around. This idea quickly evolved i...

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

... for Agriculture and the Environment, were able to solve the pathway when they discovered the gene encoding the enzyme L,L-diaminopimelate aminotransferase from the plant Arabdiopsis thaliana. The results of this discovery were published in the journal Plant Physiology in January 2006. The gene that Leu...

UCSD researchers discover internal compass of immune cell

...m bacteria and inflamed tissues. "These findings solve the long-standing puzzle of how neutrophils find their way and move toward sites of injury or infection in the body," said senior author Wolfgang Junger, Ph.D., adjunct professor of surgery at UCSD Medical Center. His team set out to identify the ...

Dinosaurs -- stones did not help with digestion

...ds which have a toothless beak, such as ostriches, solve the problem with what is known as a gastric mill. Their muscular stomach is equipped with a layer of horn and contains stones which help to break up, crush and thereby also to digest food. Giant dinosaurs from the Jurassic and Cretaceous period (2...
