Fighting antibiotic resistance with ‘molecular drill bits’

Fighting antibiotic resistance with ‘molecular drill bits’

In response to drug-resistant “superbugs” that send millions of people to hospitals around the world, scientists are building tiny, “molecular drill bits” that kill bacteria by bursting through their protective cell walls. Continue reading

Pavlov’s rats? Rodents trained to link rewards to visual cues

Pavlov’s rats? Rodents trained to link rewards to visual cues

Jan. 23, 2013 — In experiments on rats outfitted with tiny goggles, scientists say they have learned that the brain’s initial vision processing center not only relays visual stimuli, but also can “learn” time intervals and create specifically timed expectations of future rewards Continue reading

New hope for lowering cholesterol

New hope for lowering cholesterol

ScienceDaily (Mar. 1, 2011) — A promising new way to inhibit cholesterol production in the body has been discovered, one that may yield treatments as effective as existing medications but with fewer side-effects. In a new study published in the journal Cell Metabolism , a team of researchers from the UNSW School of Biotechnology and Biomolecular Sciences — led by Associate Professor Andrew Brown — report that an enzyme — squalene mono-oxygenase (SM) — plays a previously unrecognized role as a key checkpoint in cholesterol production Continue reading

Prenatal intervention reduces learning deficit in mice

ScienceDaily (Nov. 29, 2012) — Mice with a condition that serves as a laboratory model for Down syndrome perform better on memory and learning tasks as adults if they were treated before birth with neuroprotective peptides, according to researchers at the National Institutes of Health.
