Controlling neurons with light—but without wires or batteries

Posted by in categories: biotech/medical, genetics, neuroscience

University of Arizona biomedical engineering professor Philipp Gutruf is first author on the paper Fully implantable, optoelectronic systems for battery-free, multimodal operation in neuroscience research, published in Nature Electronics.

Optogenetics is a biological technique that uses light to turn specific neuron groups in the on or off. For example, researchers might use to restore movement in case of paralysis or, in the future, to turn off the areas of the brain or spine that cause pain, eliminating the need for—and the increasing dependence on—opioids and other painkillers.

“We’re making these tools to understand how different parts of the brain work,” Gutruf said. “The advantage with optogenetics is that you have cell specificity: You can target specific groups of neurons and investigate their function and relation in the context of the whole brain.”

Looking Back at 2018: A Year in Rejuvenation Biotechnology

Posted by in categories: biotech/medical, life extension

Dear friends of healthy longevity, yet another year has gone by. Hold back the melancholy though, because in this day and age a passing year can be looked at as a year fewer to wait before rejuvenation biotechnologies are available, rather than a year taken from your healthy lifespan. Busy as we are with all the errands of daily life, it is easy to forget all that’s happened and the progress we’ve made in the field in one year. So while we wait for 2019, let’s take a look back at what 2018 has brought us.

Scientists have combined a house plant with a rabbit gene. This is why

Posted by in categories: biotech/medical, habitats, sustainability

Scientists at the University of Washington (UW) may have found an unexpected way to tackle persistent indoor air pollution: a common houseplant modified with rabbit DNA.

Researchers wanted to find a way to remove the toxic compounds chloroform and benzene from the home, a UW press release explained. Chloroform enters the air through chlorinated water and benzene comes from gasoline and enters the home through showers, the boiling of hot water and fumes from cars or other vehicles stored in garages attached to the home. Both have been linked to cancer, but not much has been done to try and remove them. Until now.

“People haven’t really been talking about these hazardous organic compounds in homes, and I think that’s because we couldn’t do anything about them,” senior study author and UW civil and environmental engineering department research professor Stuart Strand said in the release. “Now we’ve engineered houseplants to remove these pollutants for us.”
