The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

...-dimensional films of the inner workings of living organisms at a much higher level of detail than ever before. One innovation of SPIM is the illumination of a sample from the side rather than along the traditional view of the microscope lens. This eliminates a problem that has plagued three-dimensional micro...

Learning to fight an adversary that won't stay down

... "superbugs," so that we can put the role of these organisms in the proper evolutionary perspective. This subject, and antibiotic resistance in particular, has fascinated Davies since he began postdoctoral work on antibiotics and resistance mechanisms at Harvard Medical School in the early 1960s. "The microbe...

Researchers identify target for cancer drugs

...rocess occurs not only in human cells but in other organisms such as the fruit fly. Finding this complex conserved in species as diverse as flies and humans supports the claim that the mTOR/rictor complex is indeed a missing piece of the puzzle. According to Sarbassov, "If we find a molecule that can block th...

Scientists identify genetic pathways essential to RNA interference

...abidopsis thaliana, both of which are common model organisms for biological research. The process interrupts the usual transfer of instructions from double-stranded DNA, through single-stranded messenger RNA and finally into proteins. Short, double-stranded pieces of RNA bind to the complementary messenger RNA...

Same mutation aided evolution in many fish species, Stanford study finds

...f evolution has other tricks up its sleeve to push organisms towards an optimal form for their environment. Other Stanford researchers who participated in the study include graduate students Pamela Colosimo, PhD, first author on the study, and Kim Hosemann; technician Sarita Balabhadra; undergraduate Guadalup...

New SARS Protein Linked To Important Cell Doorway

...equences of protein-building instructions that the organisms never use, and the researchers had no proof yet that SARS actually made use of the sequence their analysis identified. Geneticists call such sequences of genetic information open reading frames, and the SARS sequence therefore came to be known as ope...

Circles Of DNA Might Help Predict Success Of Stem Cell Transplantation

...inst their designated target. Specific infectious organisms or other foreign substances stimulate T cells to divide and multiply in order to form an attacking army. However, the sjTRECs don't multiply when the original T cells divide and multiply. Instead, the more T cells that are produced in the blood as th...

Researchers can use these structures, which are determined experimentally, to build computer models of the structures of other proteins with related amino acid sequences. Although the main focus of the second phase o...

Plants defy Mendel's inheritance laws, may prompt textbook changes
