Similar Stem Cells In Insect And Human Gut

... was Anton van Leeuwenhoek who first described the workings of a nano machine. He observed the rapid contraction of a stalk tethering the cell body of a tiny protozoan, Vorticella convallaria, to the surface of a leaf. Little did van Leeuwenhoek imagine that more than 300 years later, the biological spring th...

Scientists crack code for motor neuron wiring

...n. So, the more that is understood about the basic workings of this locomotor circuit, the better chance there is of developing regenerative strategies to restore motor function in a precise way," Jessell continued. "And in motor neuron degenerative diseases, it may not be enough make new motor neurons; they ...

UW scientists unravel critical genetic puzzle for flu virus replication

... But while much is known about the genes and inner workings of flu viruses, how the microbe organizes its genetic contents to seed future generations of viruses has remained an enduring mystery of biology. Now, with the help of a long-studied flu virus, an electron microscope and a novel idea of how the viru...

DNA conclusive yet still controversial, Carnegie Mellon professor says

...cused on using statistical tools to understand the workings of the human genome and the nature of inherited diseases. She is a member of the Bioinformatics and Statistics Genetics Group, which includes researchers in the departments of Statistics and Biological Sciences at Carnegie Mellon, and the departments...

Growing crops to cope with climate change

...UK conditions. " With the new knowledge about the workings of barley researchers and plant breeders will find it easier to select variations that will thrive in the UK environment but will also flower earlier, coping with hotter summers. Dr Laurie commented, "Although our research has been on barley we kno...

Aggression-related gene weakens brain's impulse control circuits

...g power of 'imaging genomics' to study the brain's workings in a way that helps us to understand the circuitry underlying diversity in human temperament," said NIH Director Elias A. Zerhouni, M.D., who conducted MRI studies earlier in his career. "By itself, this gene is likely to contribute only a small a...

Molecule by molecule, new assay shows real-time gene activity

...r level. Furthermore, much of our knowledge on the workings of the molecular machinery involved in gene expression comes from experiments done in vitro, rather than in living cells. Finally, the low sensitivity of current techniques for detecting gene expression has restricted analysis to highly expressed gen...

U of MN researchers develop way to visualize synchronized interactions of nerve cells in the brain

...ime. The measurements they recorded represent the workings of tens of thousands of brain cells. The large amount of data recorded from each sensor was analyzed over time to view how large groups of active brain cells operate and interact simultaneously with each other in different parts of the brain. ...

Mice lacking social memory molecule take bullying in stride

...cial defeat, BDNF and antidepressants revealed the workings of the molecular pathways involved in dopamine regulation of social motivational processes. The results suggest that chronic treatment with antidepressants restores social approach behaviors partly by interfering with the cascade of activity triggere...

Nobelist discovers antidepressant protein in mouse brain

...n Physiology or Medicine for discoveries about the workings of such neuronal signaling systems. He and his colleagues found that p11 appears to help regulate signaling of the brain messenger chemical serotonin, a key target of antidepressants, which has been implicated in psychiatric illnesses such as depress...

Inside rocks, implications for finding life on Mars

...nique, first used by biologists to study the inner workings of living cells, is new to geology. The ancient microorganisms are "pond scum," among the earliest life, much too small to be seen with the naked eye. Schopf's UCLA co-authors include geology graduate students Abhishek Tripathi and Andrew Czaja, an...

Scientists identify protein with a crucial role in cell death

...function, scientists have suspected that the inner workings of a cell depend largely on how the mitochondria function. Therefore, it has been suspected that poorly functioning mitochondria can, among other things, lead to a disturbance in brain cells and thus contribute to Parkinson's disease. A noble stra...

Cutting calories slightly can reduce aging damage

... equivalent to taking a short walk. To reveal the workings of the body's chemical climate when aging-related damage happens, UF researchers tracked levels of biomarkers - chemicals and molecules present in the liver - in groups of rats. The liver, a crucial organ for maintaining good health during aging, cle...

Most widely used organic pesticide requires help to kill

... lethal work. The startling new insight into the workings of one of the most important and environmentally friendly weapons in the human arsenal against insect pests has significant implications not only for the control of insects in agriculture, forestry and human health, but for understanding microbial di...

RNA map provides first comprehensive understanding of alternative splicing

...capacity is believed to be critical to the complex workings of human cells such as those found in the neurons of the brain. The researchers focused on a brain protein that binds to RNA called Nova. Darnell and his colleagues first identified Nova in 1993 as the target protein in a neurodegenerative disease...

NYU scientists identify how development of different species uses same genes with distinct features

...Developmental Genetics, offer new insight into the workings of developmental pathways across species. The study is published in the latest issue of the journal Science. The researchers examined the fruit fly Drosophila and the wasp Nasonia as genetic model systems. Fruit flies?development is well-understood ...

New imaging technique tracks traffic patterns of white blood cells

... the new research displays the migration and inner workings of white blood cells in the small veins and bone marrow of mice. "Intravital micropscopy (IVM) has contributed enormously to the recent mechanistic advances in leukocyte trafficking," wrote Mount Sinai School of Medicine researchers lead author Elai...

Music genes and musical geniuses

...ain enables us to understand many things about the workings of the mind ?adds Maria Majno, Executive Director of the Fondazione Pierfranco e Luisa Mariani. For example, it opens the way to research certain pathologic conditions or track and even modify children’s cognitive development. Also, it leads to imagi...

Common algae helps illustrate mammalian brain electrical circuitry
