'Redesigned' Antibodies May Neutralize HIV

May 20, 2015 7:00 am | by Vanderbilt Univ. | News | Comments

With the help of a computer program called "Rosetta," researchers have "redesigned" an antibody that has increased potency and can neutralize more strains of the AIDS-causing human immunodeficiency virus (HIV) than can any known natural antibody. The find suggests that computer-redesigned antibodies may speed the search for an effective therapy or vaccine for a virus that so far has eluded all attempts to eradicate it.

Cancer Drugs May Treat Down Syndrome, Brain Disorders

May 20, 2015 7:00 am | by Univ. of Michigan | Videos | Comments

A class of FDA-approved cancer drugs may be able to prevent problems with brain cell development associated with disorders including Down syndrome and Fragile X syndrome, researchers have found. They showed that giving the leukemia drugs nilotinib or bafetinib to fly larvae with the equivalent of Fragile X prevented the wild overgrowth of neuron endings associated with the disorder.

Nanosponges Clean Up MRSA Infections

May 18, 2015 3:00 pm | by UC San Diego | News | Comments

Nanoengineers have developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA, an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA— without the use of antibiotics.

Sugar Could Make Synthetic Opium

May 18, 2015 3:00 pm | by Concordia Univ. | News | Comments

Moonshiners and home-brewers have long used yeast to convert sugar into alcohol. Those methods could also be adapted for something more significant: the production of drugs including opiates, antibiotics and anti-cancer therapeutics. According to new studies yeast can be engineered to convert sugar to alkaloids— plant-derived compounds such as codeine and morphine, naturally produced in the opium poppy.
