Bees solve complex colour puzzles

...on humans, may enable us to understand the general principles by which any visual system (natural or artificial) can construct useful behaviour from ambiguous sensory information. 'One long-term aim of our research is to exploit this understanding to build seeing robots that, like the bee with its mere one mi...

Guiding principles for facial transplantation unveiled

...ertaking facial transplantation for a patient. The principles address such issues as: appropriate patient selection; medical facility selection; patient informed consent; patient psychological evaluation; proper institutional oversight; and the ethics of the procedure. ...

The closest look ever at the cell's machines

...findings will be more widely applicable. "The same principles discovered here in yeast apply to human cells," says Gitte Neubauer, Vice President at Cellzome. "Drug targets and pathologically relevant proteins are parts of machines and pathways." The collaboration between Cellzome and EMBL has been very succe...

Diverse tropical forests defy metabolic ecology models

...nama at STRI. And the race is on to find the basic principles governing tropical forest community composition and structure based on data from three million trees. Metabolic ecology At a U.S. National Science Foundation supported workshop, CTFS participants examined data from across the forest plot system and...

Researchers unravel DNA tangles and enzyme seamstresses

...ing part is that these seemingly abstract physical principles we work with can be useful some day to tie up DNA ...Chan's research group. "These are the same general principles that can be applied to other areas of science and engineering to address various entanglement proble...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...e rapid research advances, and in keeping with the principles pioneered by the Human Genome Project and increasingly common in such pre-competitive public/private partnerships, all data generated through these initiatives will be placed in the public domain. Background information on whole genome association ...

New test to detect rare proteins in blood

...nted. Greene's laboratory established many of the principles of targeted therapy for Her2/neu tumors and the prototype antibodies that led to the development of Herceptin, a similar antibody molecule that was created by Genentech. The Greene laboratory also previously showed that early treatment of Her2/neu tu...

ASU researchers find link between social behavior, maternal traits in bees

... can build new hypotheses that outline how similar principles might apply to other animals." ...

Life, the remake

...o spread and establish. Vermeij thinks that these principles are universal. "If we had an Earth-like planet, I think we'd see phenotypes and outcomes that parallel those on Earth," he said. ...

Genomatix technology facilitates de novo identification of new renal disease associated genes

...d to find novel interacting molecules. Here, these principles are applied to a set of genes linked to the unique functional unit of the glomerular slit diaphragm. An evolutionarily conserved promoter model was generated. Genome-wide scans using this promoter model effectively predicted a previously unrecognized...

Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species

...y is the hallmark of the living. Understanding the principles underlying the generation and maintenance of diver...irm and quantitative foundation based on the first principles underlying individual metabolism," Marquet said. ...

Researchers map out networks that determine cell fate

...cells, they suspect that the same basic regulatory principles govern cell type determination in other tissues such as skin, brain and intestine. "We see elements of this framework of primary and secondary cell-fate determinants throughout the hematopoietic system," said study author Harinder Singh, the Louis ...

Flick of a protein switches immune response

...as far-reaching implications for understanding the principles of signal transduction and transcriptional networks of living cells," Chen said. The Cell paper, which Chen describes as spanning 14 years of laboratory work, builds on a result his group published in Nature in 1998. ...

Study finds how organs monitor themselves during early development

...insect is helping researchers to grasp fundamental principles of biology and body function, explains Dr. Gilboa....n other fields and they can build on those general principles to further their work," she says. A researcher studying the challenge of infertility in humans could...

Researchers uncover new mechanism of tumor suppressor

...n. "Our findings have established the mechanistic principles by which the inhibitor of growth 2 tumor suppressor recognizes chromatin and regulates cell growth, proliferation, stress responses and aging. We hope this discovery opens up new opportunities to establish novel targets to prevent and treat cancer," ...

Connect the Quantum Dots

...imilliano Tomasulo were able to identify operating principles to probe molecular recognition events with luminescence measurements. These findings demonstrate that mechanisms based on photoinduced electron transfer can be exploited to transduce a recognition event into a significant change in the luminescence ...

New roles for growth factors: Enticing nerve cells to muscles

...but that piece by piece, we are uncovering general principles that ensure that the developing nervous system establishes proper neuronal connections." Understanding how axons find their destinations may help restore movement in people following spinal cord injury, or those with motor neuron diseases such as L...

Drug dials down the energy within cells, UM researchers find

...to function. This is important because it suggests principles that may be useful for targeting other bioenergetic pathways. Now we have some rules that we can apply to be able to modulate the mitochondria in new ways that could be therapeutic." Ultimately, the findings may have applications not only for lupus,...

How nature tinkers with the cellular clock

...e new insights gained have broad implications. The principles discovered might govern also the control of other temporally regulated systems like embryonic development. The fast evolution of temporal regulation also raises the question in how far general conclusions about regulatory systems can be drawn from st...

What animals can tell us about hemorrhage, organ transplants and aging

... they do that?" They uncover general physiological principles that may apply to humans, and may spur future medical advances to benefit people. These scientists exude an enthusiasm for their work and maintain a wonderment of the physiological adaptations in the animal world. Science writers can meet and inter...
