Gene mutation found for a form of juvenile-onset motor neuron disease

...e damaged in other forms of ALS. "After scientists figure out what protein the normal gene produces and what this protein does in normal cells," Chance said, "they may determine how the mutation disturbs cellular functions in ALS patients. We need to know more about the underlying basis of motor neuron dege...

Imaging the brain solving problems through insight

...ry a zillion different combinations and eventually figure it out. But with insight, you'd experience the usual clueless confusion, until--voil--the fog clears and you get the clue, which suddenly seems obvious. The sudden flash of insight that precedes such "Aha!" moments is characteristic of many types of ...

Scientists question reports of massive ant supercolonies in California and Europe

...r years, Gordon and other scientists have tried to figure out why these tiny invaders are such remarkably successful colonizers, not only in the United States but also in the Mediterranean and other parts of the world. In May 2000, biologist Neil D. Tsutsui and his colleagues from the University of Calif...

Long-forgotten samples may help save species

...example, the information may help conservationists figure out which captive snail populations are best to reintroduce to the wild and which of the remaining wild populations they should focus future conservation efforts on. "The story here, in terms of conservation biology, is a horror story, but it'...

'Crystal engineering' helps scientists solve 3-D protein structures

...engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules, including a key plague protein whose structure has eluded researchers until now. The technique, developed with support from the National Institute of General Medical Science...

Gene with key role in replicating pox viruses also halts inflammation

... for replicating within the host cell, then we can figure out how to inhibit them and halt the viral replication," she said. Post 9-11 fears of bioterrorism by means of the deliberate introduction of smallpox have spawned renewed interest in new, safer vaccines against the deadly disease, which was eradicat...

Scientists develop new cloning technique that dramatically shortens the search for genes

...ousands of genes, and using traditional methods to figure out what each one does is a time-consuming process. "The standard approach used by plant geneticists known as gene cloning involves breaking down the system in a very controlled way, and then hunting down what's broken," Mitra explained. This proce...

New paclitaxel analog kills more cancer cells than natural product

...litaxel is sitting on the microtubule? If we could figure that out, we could design a molecule that would plug in better than paclitaxel for better binding and possibly better activity against cancer. What is the right conformation of the side chain?" One hypothesis was put forward by Jim Snyder of Emory U...

McGill scientists publish detailed picture of how nutrients and other molecules get into cells

...lex machine into its component parts. We can then figure out how it is assembled, how the proteins interact with one another, and what goes wrong in disease. "The study from Dr. McPherson and his colleagues is fundamental to our understanding of the cellular uptake process because it provides a comprehen...

Purdue chemists 'put the twist' on protein building block

...u excited it with a jolt of energy. So we tried to figure out precisely how much of a jolt was necessary to make it assume a particular shape." Zwier's group mixed gaseous tryptamine with helium, which was used to cool the molecules to very low temperatures. They then excited the tryptamine molecules ...

American Society for Investigative Pathology (ASIP) offers sessions on topics including lung injury and repair, free radicals in disease pathogenesis, immune mechanisms of CNS disease, aging and determinants of longevit...

Life in the universe takes orders from space

...s. "There is a fundamental difficulty in trying to figure out how you go from confusion and randomness to functionality and specificity," said Pizzarello. So far, only one trait has been found to be similar, to some extent, between amino acids in meteorites and biopolymers, that of L-"handedness" (chiralit...

UCSF finding advances insight into adult stem cells in human brain

...SF professor of neurological surgery. "We want to figure out what makes the astrocytes in the subventricular zone special," says Sanai. "Are there other astrocytes in the human brain with the potential to function as stem cells? If we identify the necessary molecular signals, can we unlock this potential i...

Three personal ads for physics

...am, Kakalios has found that his students prefer to figure out if Spider Man's webbing could support his weight if it were as strong as a real spider's silk. Once the concepts are introduced, to answer fun questions, Kakalios explains their real-world applications to automobile airbags, cell phones, nanotech...
