A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists. Therapy…

Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it…

Will we domesticate biotechnology in the next 50 years? More than 150 years of spectacular advances in physics, chemistry, and computing have thoroughly transformed the way we live. Yet so far, the…

A new study, published in the August issue of Glycobiology, found that exposing prostate cancer cells to pectin under laboratory conditions reduced the number of cells by up to 40 percent.…

By creating "Teflon" versions of natural antibiotics found in frog skin, a research team led by biological chemist E. Neil Marsh has made the potential drugs better at thwarting bacterial defenses,…

Errors in the genetic code can give rise to cancer and a host of other diseases, but finding these errors can be more difficult than looking for the proverbial needle in the haystack. Now, scientists…

Evidence from laboratory experiments on rats and on human colon cancer cells also suggests that anthocyanins, the compounds that give color to most red, purple and blue fruits and vegetables…

Scientists have determined for the first time the atomic structure of an ancient protein, revealing in unprecedented detail how genes evolved their functions. "Never before have we seen so clearly,…

Individuals with chronic myeloid leukemia (CML) are treated first with a drug known as imatinib (Gleevec), which targets the protein known to cause the cancer (BCR-ABL). If their disease returns,…

    If there is a group of humans who whose fate tracks with that of lab mice, it is that of the Caloric Restriction Society, whose members make a lifestyle out of the long-noted fact…
