Natural anti-viral enzyme helps keep cancer cells alive, researchers find

...ot essential in normal cells. "This is making us think that there are many other surprises awaiting discovery regarding biological systems that are inappropriately subverted during development of cancer," Dr. White said....

LSD treatment for alcoholism gets new look

... with LSD. "We accept all sorts of drugs, but I think LSD's 'street' popularity ultimately led to its demise," Dyck said. "And that's too bad, because I think the researchers in Saskatchewan, among others, showed the drug is unique and has some intriguing pro...

Train your brain to hear your friends at a party

Gene-bender proteins may sway to DNA

... needed for a tight DNA-protein fit. Scientists think DNA is largely passive in this genetic tango. But new findings by Anjum Ansari, associate professor of biophysics at the University of Illinois at Chicago, suggest DNA may not be the wallflower that many had assumed. To follow in real time the stru...

RNA map provides first comprehensive understanding of alternative splicing

...of complexity to brain processes that enable us to think and learn, exactly how alternative splicing is regulated during these processes -- and in some cases is uncontrolled (or dysregulated) to cause disease -- has remained elusive. The map provides the first comprehensive understanding of how alternative...

Mysterious 'neural noise' actually primes brain for peak performance

Hopkins researchers discover how brain protein might control memory

... like drug addiction, the researchers say. "We think Arc controls how brain cells learn and associate behaviors and remember them over a long period of time," says Paul F. Worley, M.D., professor of neuroscience and neurology at Hopkins and director of both studies. "For example, the person who quits s...

Fast test for low blood flow in dogs detects early heart trouble

...nute to 8 milliliters per gram per minute. "We think this is a natural evolution of the technology and a significant improvement in our ability to diagnose problems with blood flow," says George, who conducted the study from June to September 2006. George adds that larger clinical studies are planned ...

Scientists win grants to develop $1,000 genome sequencing technology

...ly $1,000 is an enormously challenging task, but I think we have as good a chance as any group to get there first." Huang's group was awarded $275,000 for one year with the possibility up to an additional $3 million over three more years if specified milestones are met in the initial experiments. Huang ...

Teenager moves video icons just by imagination

...ic arm or leg by thinking about it. Many gamers think fondly of Atari's Space Invaders, one of the most popular breakthrough video games of the late '70s. The player controls the motions of a movable laser cannon that moves back and forth across the bottom of the video screen. Row upon row of video alie...

Plant-derived molecules, genetic manipulation point to future chemoprevention methods

... only avenues to combat this particular cancer. We think this study shows a promising role for triterpenoids and the drug LG100268 in stopping lung tumor growth." The scientists knew that the compounds had anti-inflammatory properties and that LG100268 in particular could stop certain types of breast ca...

LSU professor discovers new species

An artificial cornea is in sight, thanks to biomimetic hydrogels

...nt material in diapers. "Think of a fishnet, but think of a 3-D fishnet," says Frank, the W. M. Keck, Sr. Professor in Engineering and a professor, by courtesy, of chemistry and of materials science and engineering. "It's a strong, stretchy material." That makes it able to survive suturing during surgery...

Electric jolt triggers release of biomolecules, nanoparticles

...erican Chemical Society in San Francisco. "You can think of the useful biomolecule or nanoparticle as a balloon tethered to a surface," he said. "We use an electrical pulse to cut the tether, and it floats away." This method could be used to control the release of drug molecules; nanoparticles; biopolyme...

Novel regulatory mechanism identified for key tumor suppressor p53

...hey wouldn't be able to divide, and they'd die. We think this new mechanism may be a way for the cell to keep p53 turned off but present, ready to be activated if the DNA should be damaged." In their study, the scientists identified an enzyme called Smyd2 that adds a methyl group to the p53 protein at a ...

Engineer ramps up protein production, develops versatile viral spheres

...otein assemble into a nanoscale soccer ball. "We think these little spheres, 27 nanometers in diameter, will form the basis for a new class of pharmaceuticals and a new class of materials," Swartz says. "For example, to date we've been seriously limited in our ability to both produce and to modify capsid...

New dyslexia theory blames 'noise'

...lexia rivals the confusion of dyslexia. Many still think that to have dyslexia means to mix up your letters (one of many possible symptoms having to do with word recognition, directional ability and decoding of symbols). What is known is that dyslexia affects millions of children, with estimates of its...
