MIT, Brigham: Nanoparticles armed to combat cancer

...hicles because they are so small that living cells readily swallow them when they arrive at the cell's surface. Langer said that particles larger than 200 nanometers are less likely to get through a cell's membrane. A nanometer is one-billionth of a meter. The Farokhzad-Langer team created particles that ar...

Biologists estimate the value of services provided by insects

...f forage to cattle, and make nitrogen in dung more readily available to plants. The authors estimate the value of natural control of crop pests attributable to insects at $4.5 billion annually. Native pollinators--almost exclusively bees--seem to be responsible for over $3 billion-worth of fruits and vegetab...

Cellular scale drug delivery from the inside out

... said. "They're also biocompatible so they can be readily absorbed by the cells." But it's the structure of the nanospheres that makes drug delivery possible. The spheres have thousands of parallel channels running completely through them. Through capillary action, the spheres can soak up molecules of the d...

Novel newborn screening can open door to treating rare but devastating diseases

...rticularly early in life when the symptoms are not readily apparent. The new screening method will allow precise diagnosis very early, so newly developed pharmaceutical treatments can be administered in time to repair the break in the lysosome's biochemical chain and stop further damage. After an initial inv...

Getting ACL tears to heal themselves

... was firm enough to be used as a bridge and wasn't readily dissolved by joint fluid. In the future, Murray hopes to extend her technique to other injuries like meniscus and rotator-cuff tears. Her ultimate dream is cartilage regeneration to repair joints damaged by osteoarthritis. No one has yet been able to...

Minimal cocktail for growing human embryonic stem cells established

...sy to grow in an undifferentiated state and can be readily induced to differentiate into all the three basic cell lineages." The final cocktail for HESCO, that actively support hESC self-renewal, contains the growth factor Wnt3, basic fibroblast growth factor, insulin, transferrin, the B-cell activating fact...

New RNAi tools enable systematic studies of gene function

...nds of genes using RNAi allows researchers to more readily pinpoint the genes that control a biological process. Therefore, TRC developed the high-throughput techniques and quality-control measures required for such genome-scale studies. "It is a distinct challenge to achieve consistent and cost-effective RN...

Do plant species really exist? Why, yes, scientists say

... been way over-attracted to the plant species that readily hybridize and where the hybrids perpetuate themselves asexually. While it's true that dandelions and blackberries pose problems, these horror stories only make up 1 percent of the whole." The scientists did find categorization problems with nearly ha...

News tips from the Journal of Neuroscience

...lease by approximately one-half. However, when the readily releasable DA pool was depleted, cocaine still increased DA release, suggesting that cocaine also affects the reserve pool of vesicles. Because synapsins bind to vesicles and segregate them into reserve pools, the authors tested cocaine in a knock-ou...

Novel vaccine approach stimulates protective immunity against listeria

...enuated Listeria strain does not replicate, and is readily killed. Unlike other attenuated Listeria strains that do not replicate in host cells, vaccine studies in animals showed that the new strain provided protection from challenge with a virulent, disease-causing, Listeria strain. "For the first time, a...

Alzheimer's study first to explain death of brain cells

...ch results, Atamna's team showed that amyloid-beta readily binds with heme to form a compound that can be flushed from cells. When there is insufficient heme or too much amyloid-beta, however, the amyloid-beta forms large toxic "clumps" that the cell cannot dissolve and eliminate. Though heme binding with a...

Reining in carbon dioxide levels imperative but possible

...so see widespread use of hybrid engines as another readily deployable technology to help reduce carbon dioxide emissions. All together, a program to keep the Earth's carbon dioxide levels in check could cost less than 1 percent of projected gross world product as of 2050. "Whatever we do, we know we are goin...

Vanderbilt-Ingram Cancer Center receives funding for novel breast cancer and obesity studies

...ing or to identify it early enough when it is more readily treatable," said William Blot, Ph.D., professor of Medicine and project coordinator. According to the American Cancer Society, over 200,000 women in the United States will be diagnosed with breast cancer in 2006. Julie Means-Powell, M.D., a medical o...

New method for identifying microbes

...t are short enough to be sequenced rapidly and can readily distinguish among species. The Brookhaven team has developed just such a technique, which they call "single point genome signature tagging." Using enzymes that recognize specific sequences in the genetic code, they chop the microbial genomes into sma...

Weighting cancer drugs to make them hit tumors harder

...so remain longer in the tumor because they are not readily reabsorbed into the bloodstream, nor can they penetrate the kidneys to be cleared from the body. They must wait for the liver to break them up and dispose of them via the intestines. "Our goal was to increase the tumor dose and lower the systemic dos...

Microbes convert 'Styrofoam' into biodegradable plastic

...have a long shelf life. But unlike polystyrene, it readily breaks down in soil, water, septic systems and backyard composts. Worldwide, more than 14 million metric tons of polystyrene are produced annually, according to the U.S. Environmental Protection Agency. Most of this ends up in landfills. Although pol...

Changes in reef latitude

As they do now, sediments rich in phosphorus historicall...

Detection of DNA on nanotubes offers new sensing, sequencing technologies

"The optical detection of specific DNA sequences through hybridization with a complementary DNA probe has many potential applications in medicine, microbiology and environmental science," said Esther Jeng, a graduate student at Illinois ...

AAAS denounces anti-evolution laws as hundreds of K-12 teachers convene for 'Front Line' event

"The scientific community stands beside teachers as they work to provide students with an appropriate grounding in science and ma...
