Digging in the dirt for life's biochemical foundations

... this evolutionary bargain for years, but specific details remained fuzzy, especially those related to nitrogen. To learn more about nutrient uptake, MSU researchers led by Shachar-Hill, along with collaborators at New Mexico State University and the U.S. Department of Agriculture research center near Phila...

Newly Discovered Role for Heart Response Enzyme May Yield Better Heart Failure Therapy

... advance online publication. "We've uncovered new details of the first step of heart failure, in which heart receptors that normally allow the heart to adapt in the face of changing conditions are lost, rendering the heart unable to pump enough blood to meet the needs of the body's other organs," said cardi...

Researchers find how some antibiotics kill bacteria

...functioned," Artsimovitch said. "The new molecular details help explain why bacteria that are resistant to one kind of rifamycin antibiotic might still be sensitive to another. "That may help to narrow down the search for new synthetic derivatives to conquer resistance altogether." The study appears in the...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

... due to diffraction. It seemed impossible to image details smaller than a distance where delta d is equal to 200nm using conventional lenses and visible light. For a long time, Abbe's law was regarded as being insurmountable. For higher resolution, the textbook knowledge was that a complicated and costly el...

Researchers discover new tumor defense system

... may give a boost to anti-cancer therapeutics. The details of these findings appear in the September issue of the Journal of Lipid Research, an American Society for Biochemistry and Molecular Biology journal. Several forms of anti-cancer therapy rely on what is known as immunotherapeutic anti-cancer strateg...

Environment, not genes, key in family relationships

...epartment. "But direct evidence of this and of the details of such a process must await appropriate longitudinal studies." "While these findings in themselves have no immediate practical implication," he continued. "But they should help guide future research into the important question of how children's gen...

New discovery blurs distinction between human cells and those of bacteria

UCLA biochemists reveal the first structural details of a family of mysterious objects called microcompartments that seem to be present in a variety of bacteria. The discovery was published Aug. 5 in the journal Science. "This is the first look at how microcompartments are built, and what the pieces l...

Scientists discover new way to look at how molecules twist and turn on water

...environmental challenges Chemists have discovered details about how the tadpole-shaped molecules found in many soaps and detergents bury their heads into the top-most surface of water, an insight expected to yield benefits such as better methods for cleaning up environmental hazards. The findings of a tea...

'License to kill' enables powerful immune attack cells in mice

...ule on the surfaces of other cells. The molecular details of the process were so unusual that Yokoyama and h...ection to the world of cinema spies: the molecular details of the process feature a player who is comparable to a double agent. Scientists have known for some ...

Grasshopper love songs give insight into sensory tuning

... with grasshopper auditory neurons that reveal new details of such sensory coding. Their findings show that "optimal stimulus ensembles" that trigger the neurons differ from those the grasshopper hears in the natural environment but largely overlap with components of natural sounds found in mating and mate-l...

Baby's genes affect mom's cholesterol levels

... by her genes but by her baby's genes as well. The details of their findings appear in the November issue of the Journal of Lipid Research, an American Society for Biochemistry and Molecular Biology journal. The researchers, led by Olivier S. Descamps of the Centre de Recherche Medicale de Jolimont in Haine...

Master regulatory gene found that guides fate of blood-producing stem cells

...-producing stem cells, in bone marrow. Knowing the details of this pathway may one day lead to new treatments for such blood diseases as leukemia, as well as a better understanding of how HSCs work in the context of bone-marrow and peripheral-stem-cell transplantation. The authors published their findings i...
