North & South American researchers find architectural abnormalities in T. cruzi ribosome

...e evolution of more complex organisms. "Ribosomes perform the translation of genetic information into protein in all organisms," Frank said. "The principle is always the same in plants, bacteria, and humans. It's a fundamental property of life on Earth." Another HHMI investigator, Thomas A. Steitz of Yale ...

NHGRI expands effort to revolutionize sequencing technologies

...idic electro-wetting technology can be modified to perform sequencing by synthesis reaction chemistry. This method allows for smaller volumes of materials to be used as well as the decoupling of synthesis and detection steps, resulting in more efficient automation. M. Reza Ghadiri, Ph.D., The Scripps Resear...

New technology shows our ancestors ate…everything!

...cope is programmed to step down at fine intervals, perform its series of scans, and collect 3D coordinates for each data point," said Teaford. The result is like a map of the earth that shows mountains, valleys and plains in full relief, only at a microscopic scale. As anticipated from traditional examinati...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

... DNA molecule at the UV damage site temporarily to perform repairs. They also report something that was unexpected: Water plays a key role in the process, by regulating how long the donated electron stays inside the damage site before returning to the photolyase molecule. Scientists believe that all placen...

New research puts a fresh spin on current thinking of speech evolution in humans

... that this area of the brain evolved originally to perform high-order control over the mouth and the jaw, and that as humans evolved this area came to control the movements necessary for speech. "Our study shows that nonlinguistic monkeys possess an area comparable to Broca's area ?it is located in the same...

K-State professors discover enzyme responsible for creation of a beetle's hard shell

...he mechanical properties of insect cuticles and to perform cuticle protein cross-linking experiments that are catalyzed by insect laccase, Kramer said. KU scientists will test the strength of the synthetic cross-linked biopolymers that are created. This could be used for the development of strong, lightweigh...

Displaced songbirds navigate in the high Arctic

... migrating birds that breed in northern Canada and perform long migrations covering a few thousand kilometers to winter in the southern United States. In the study, young and adult white-crowned sparrows were captured with mistnets near Inuvik, NW Territories, Canada, during mid-July to mid-August--the end o...

Biotechnology's newest chemical tool

... evolution, the opposable thumb, so the device can perform different grasping actions. Taking inspiration from the real hand, where a muscle pulls a tendon inside a synovial sheath, CYBERHAND's finger cables run through a Teflon sheath pulled by a DC motor. So the proximal, medial and distal phalanges, tho...

Plants reveal a secret and bring researchers nearer a cleaner future

...very intense and stable X-ray beam is necessary to perform this study on such a complex, highly diluted protein present in the investigated spinach sample", explains Pieter Glatzel, head of beamline ID26, where the experiments were carried out. The researchers measured the fluorescence from the sample that ...

Research Permits First-Ever Visualization of Psychological Stress in the Human Brain

...ntal cortex is also associated with the ability to perform executive functions -- such as working memory and goal-oriented behavior -- that permit humans to adapt to environmental challenges and threats. "The message from this study is that while stress may be useful in increasing focus, chronic stress could...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...rkers for other cancers. They are also planning to perform animal studies, examining the sensitivity of the antibody-nanotube system in detecting cancer cells in the blood and in detecting specific types of cancer cells shed in the blood from tumors.

Genetic testing still smart choice, despite uncertainties

...ided a third time, typically the time when doctors perform preimplantation genetic diagnosis. This is where the problem with diagnosis occurs, researchers say. "Our pathway concept may help to explain the observed outcomes during preimplantation diagnosis," said Kenneth Drury, Ph.D., director of the UF IVF ...

Mining biotech's data mother lode

...elevant to the topic. Finally, the researcher must perform a search of academic journals to find relevant journal papers. Currently PubMed, the most important public literature database available, has 15,000,000 entries, and the number is growing every day. Finding relevant data there is again not a trivial ...

Penn Surgeons Use Completely Robotic Surgery to Successfully Treat Prostate Cancer
