Dinosaur hearing, listening to muscle noise, quieter cubicles

...and scanner operators. Acoustical researchers are devising various approaches to making the machines quieter. A UK team (including Deborah Hall, MRC Institute of Hearing Research, Nottingham, d.hall@ihr.mrc.ac.uk ) will present an active noise control system that cancels out some of the sound from the mach...

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

...s and ages. The team's research is a major step in devising a therapy to reverse permanent hearing loss because it may lead to the activation of cochlear stem cells in the inner ear to regenerate new hair cells. “Clearly we have miles to go before we reach our end goal, but the exciting part is now we can te...

3-D ultrasound identifies women at risk for impending preterm birth

...al adrenal gland volume can assist clinicians with devising better therapeutic and preventive interventions for preterm birth....

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

...the way for improved study of hepatitis C virus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines. The related report by Lázaro et al, "Hepatitis C virus replication in t...

Weighty viruses

...echniques and a miniaturized ion trap of their own devising to accurately analyze the masses of individual, intact viruses. Previous methods for determining the masses of viruses had a margin of error of ±15%, which made them too inaccurate to ensure the resolution of small differences in mass. A team led by...

Striking the right balance between excitation and inhibition

Combination therapy with a monocloncal antibody and a vaccine leads to tumor rejection

... cell population. Researchers continue to work on devising ways to mobilize anti-tumor Teff cells in order to better shape the immune response to tumors. Previously, James Allison and colleagues from Memorial Sloan-Kettering Cancer Center, New York, demonstrated that an anti–CTLA4 monocloncal antibody used i...

Honeybee decision-making ability rivals any department committee

...er Kevin Passino have been observing, videotaping, devising experiments and mathematically modeling honeybee swarms. "The bees' method, which is a product of disagreement and contest rather than consensus or compromise, consistently yields excellent collective decisions," said Seeley. When a hive gets to...

Picking particles faster than one at a time

...ion. Understanding structure is often the key to devising antibiotics and other therapies that can interfere with unwanted biological activity -- for example, the ability of infectious bacteria to synthesize proteins can be wrecked by jamming their ribosomes, if the ribosome structure is known in detail. Si...

Brains response to visual stimuli helps us to focus on what we should see, rather than all there is to see

...sted the prevailing notion of columnar function by devising an experimental method that used glass microelectrodes to "listen" to two neurons at a time. They used rats, whose brain organization mirrors that of a human, and dissected tiny vertical slices to preserve the circuitry. With fine glass pipettes, the...

U-M scientists say fused genes trigger the development of prostate cancer

...tational biologists around the world who have been devising ways to infer or extrapolate these haplotypes from the flood of genotype data produced by DNA sequencing efforts. Eskin and Ph.D. candidates Noah Zaitlen and Hyun Min Kang at UCSD, and research scientist Eran Halperin at ICSI, worked with NCBI scient...

California computer scientists double volume of data in NIH biotech repository

Scientists create digital bacteria to forge advances in biomedical research

...ting to Cluzel's lab, Emonet worked with Rosner in devising simulations to understand how the sun reverses its magnetic field every 11 years. Each digital cell in AgentCell is a virtual Escherichia coli, a single-celled bacterium, which is equipped with all the virtual components necessary to search for food...

Immune system's distress signal tells bacteria when to strike back

... of years, Alverdy said, with each side constantly devising novel measures, countermeasures, and counter-countermeasures, including sophisticated mutual espionage. The discovery of antibiotics gave human hosts a temporary advantage, "but that seems to be waning a bit," he added. "We need to learn new ways to...

NYU and MSKCC research provides model for understanding chemically induced cancer initiation

...dded NYU's Broyde. "Such information is needed for devising novel preventive and therapeutic strategies for addressing the problem of cancer induction by environmental chemical carcinogens." The researchers added that the finding opens new horizons, at the molecular level, for understanding the effects of me...
