A buffet for early human relatives

...topes or forms of carbon. Plants fall into two broad classes depending on the way in which they use photosynthesis to convert sunlight, water and carbon dioxide into plant matter and oxygen. Carbon isotope ratios reveal the extent to which the relatives of early humans ate so-called C3 plants, which in...

The subtleties of tropical forest demise

...ging threats. "We designed this book for a very broad audience," said Laurance. "It's for anyone interested in the fate and survival of tropical ecosystems. "The book includes syntheses by many world-leading authorities as well as original, data-rich studies. About the Editors William Laurance is a ...

GlycoFi and Dartmouth report full humanization of yeast glycosylation pathway in Science

...have engineered yeast cells capable of producing a broad repertoire of recombinant therapeutic proteins with fully human sugar structures (glycosylation). These sugar structures ensure a glycoprotein's biological activity and half-life and to date, have necessitated the expression of therapeutic glycoprote...

Controlling antibiotics and antibiotic resistance in hospitals

...ce of antibiotic resistance, while simply limiting broad spectrum drugs helped prevent resistance. "We think this may be because wrong decisions are made about which antibiotics are made available. Other studies have shown evidence that restricting formularies to previously effective antibiotics can act...

Supercomputing equipment to advance the frontiers of computational biology

...stem, with the goal of making these available to a broad community of users. The project's principal investigators at Rensselaer are Angel Garcia, senior constellation chaired professor in biocomputation and bioinformatics; Mark Shephard, the Samuel A. and Elisabeth C. Johnson Jr. Professor of Engineeri...

Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

...owth of every polymer chain, all while employing a broad range of monomers. Much of the research progress and commercial success related to ATRP is due to two research consortia Matyjaszewski has initiated and led. These successful consortia have allowed many companies to incorporate ATRP methodologies i...

From a lowly yeast, researchers divine a clue to human disease

...m, the Wisconsin group developed a method to get a broad view of how Sen1 works and what happens when it doesn't work properly. Normally, Sen1 acts like a molecular stop sign, telling another protein called RNA polymerase II when to stop transcribing genetic information from DNA into related threads of R...

Plants give up answers in the war on bacteria

...the mysteries of plant pathologies, but these have broad implications," He said. "We haven't understood very well how plants and bacteria interact, but we're finally seeing the light." ...

A key antibody, IgG, links cells' capture and disposal of germs

...hose handled by IgG." While just one of several broad classes of human antibodies, IgG is by far the most important -- so much so that patients incapable of making their own antibodies to fight off infections are routinely treated with IgG alone. Broadly speaking, the immunological powerhouse manages th...

Regulating the nuclear architecture of the cell

...ey do die." Says Karpen, "These findings have broad implications for genome stability. We plan to investigate whether the H3K9 and RNAi pathways we've identified in Drosophila play the same role in humans; if so, misregulation of heterochromatin could be one cause of the rampant genome instability obs...

Hormone linked to brain's cravings for food and other energy sources

... in the hypothalamus, has now been shown to have a broad influence on various brain functions. "This makes sense because the major driving force of life is seeking energy to survive," he said. "Future studies will explore the relationships between ghrelin and cocaine addiction." ...

New dyslexia theory blames 'noise'

...is quite general and has to do with attention in a broad sense.... "This is a great paper of very high significance... As people like Steve Grossberg [of Boston University] have argued for many years, attention ... is crucial for stable learning of categories." Ziegler called for preventive training...

Patients can report statins' adverse effects on new web site

..." said Golomb. The site will provide access to a broad group of people, facilitating the opportunity for patients to confidentially share information about their experience, said Golomb, who adds that a comprehensive understanding of the impact of cholesterol-lowering medications, including statins, has ...

Genomic comparison of lactic acid bacteria published

...mited range of biosynthetic capabilities promising broad industrial applications. Lactic acid-producing bacteria play a key role in the production of fermented foods and beverages, accounting for tens of billions of dollars in sales annually. Products constituting a fine repast, such as wine, salami, ch...

Effective HIV control may depend on viral protein targeted by immune cells

...?approach, seeking to generate responses against a broad range of viral proteins, but these results challenge that dogma." While many strategies for developing a vaccine to control HIV focus on the activity of the CD8 T lymphocytes that recognize and destroy virus-infected CD4 T cells, the fact that ev...

Advance helps explain stem cell behavior

...cesses of cellular development are understood in a broad sense, the detailed biochemistry that underlies and controls these processes is still poorly defined. The overall process appears to be incredibly complex with many pieces and "combinatorial interactions." Still unknown is exactly what causes certa...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

...cause it may provide a motivational tool that is a broad set of concrete, tangible, and rapid benefits of sobriety: cognition, chemistry and brain volume," wrote the associate professor of diagnostic radiology and psychiatry at Yale University. Prof Mason believed this was a particularly valuable contribu...

Changing length of days reverses how estrogen affects aggressiveness in mice

...s research has just begun, the findings could have broad implications in humans, for issues such as aggression and the role of estrogen in promoting cancer, Trainor said. Nelson and Trainer presented their results Oct. 18 in Atlanta at the annual meeting of the Society for Neuroscience. A major findi...

Novel EGFR ectodomain mutations in glioblastoma

Coral reefs are increasingly vulnerable to angry oceans

...vulnerable corals are "table" corals, which have a broad flat top supported by a narrow stalk, making them more susceptible to strong wave forces than bushy or mounded corals. Vulnerability also depends on whether the coral grows on the front, crest, flat or the back of the reef, where the force of the wav...
