Bacterial Nano-wires

For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric wires, using them to power themselves and transfer electricity to a variety of solid surfaces.

Today, a team led by scientists at USC has turned the study of these bacterial nanowires on its head, discovering that the key features in question are not pili, as previously believed, but rather are extensions of the bacteria’s outer membrane equipped with proteins that transfer electrons, called “cytochromes.”

Scientists had long suspected that bacterial nanowires were pili – Latin for “hair” – which are hair-like features common on other bacteria, allowing them to adhere to surfaces and even connect to one another. Given the similarity of shape, it was easy to believe that nanowires were pili. But Moh El-Naggar, assistant professor at the USC Dornsife College of Letters, Arts and Sciences, says he was always careful to avoid saying that he knew for sure that’s what they were.

“The pili idea was the strongest hypothesis, but we were always cautious because the exact composition and structure were very elusive. Then we solved the experimental challenges and the hard data took us in a completely different direction. I have never been happier about being wrong. In many ways, it turned out to be an even cleverer way for bacteria to power themselves,” said El-Naggar, corresponding author of the study, who was named a Popular Science Brilliant 10 researcher in 2012 for his pioneering work with bacterial nano-wires.

By depriving the bacteria of oxygen, the researchers were able to force the bacteria to stretch out their nanowires on command, allowing the process to be observed in real time. And by staining the bacterial membrane, periplasm, cytoplasm, and specific proteins, researchers were able to take video of the nanowires reaching out – confirming that they were based on membrane, and not pili at all.

Love your muscles!
The love hormone oxytocin helps old mice regenerate muscle tissue as well as young mice do, (in picture, muscle proteins are stained in red, DNA in blue).
UC Berkeley researchers have discovered that the hormone - associated with maternal nurturing, social attachments, childbirth and sex - is indispensable for healthy muscle maintenance and repair, and that in mice it declines with age.
The new study, published in the journal Nature Communications, presents oxytocin as the latest treatment target for age-related muscle wasting, or sarcopenia. A few other biochemical factors in blood have been connected to aging and disease in recent years, but oxytocin is the first anti-aging molecule identified that is approved by the Food and Drug Administration for clinical use in humans, the researchers said.
Pitocin, a synthetic form of oxytocin, is already used to help with labor and to control bleeding after childbirth. Clinical trials of an oxytocin nasal spray are also underway to alleviate symptoms associated with mental disorders such as autism, schizophrenia and dementia. “Unfortunately, most of the molecules discovered so far to boost tissue regeneration are also associated with cancer, limiting their potential as treatments for humans,” said study principal investigator Irina Conboy, associate professor of bioengineering. “Our quest is to find a molecule that not only rejuvenates old muscle and other tissue, but that can do so sustainably long-term without increasing the risk of cancer.”
Conboy and her research team say that oxytocin, secreted into the blood by the brain’s pituitary gland, is a good candidate because it is a broad range hormone that reaches every organ, and it is not known to be associated with tumors or to interfere with the immune system.

BABY CORALS AND FISH SMELL THEIR WAY TO TH BEST HOME

New research suggests that these creatures, baby fish and coral larvae, smell their way to neighborhoods where the living is good. Scents emitted by certain species of adult corals draw fish and coral larvae to healthy reefs, while the noxious odor of out-of-control seaweed drives them away from damaged ecosystems.
Young fish and coral larvae are cast out into the open ocean after they are born, to swim or float away on currents to new ecosystems. Some eventually return to their spawning grounds—especially if their hometown happens to be in a protected marine habitat—while others settle elsewhere. But these days, many fish and coral larvae are finding themselves with limited options: More and more unprotected reefs have been taken over by seaweed, which smothers coral, disrupts food webs, and perhaps even poisons potential settlers.Both fish and coral larvae have been observed navigating away from those degraded reefs and toward healthy ecosystems. A baby coral is “a bag of snot with some cilia around it. How could it go one place and not another?”…… continue reading

Graphene-Based Artificial Retina Sensor Being Developed

Researchers at Germany’s Technical University of Munich are developing graphene sensors like the ones depicted above to serve as artificial retinas. The atom-thick sheet of linked carbon atoms is being used because it is thin, flexible, stronger than steel, transparent and electrically conductive. 

TUM physicists think that all of these characteristics and graphene’s compatibility with the body make it a strong contender to serve as the interface between a retinal prosthetic that converts light to electric impulses and the optic nerve. A graphene-based sensor could help blind people with healthy nerve tissue see, they say.
