Leopard geckos can grow new brain cells, study finds

Science
July 27 (UPI) -- Many reptiles and amphibians boast impressive tissue regeneration abilities. But only geckos are known to be able to grow new neurons. For the first time, University of Guelph researchers have identified the presence of stem cells responsible for neuron generation in the brains of leopard geckos. Scientists used a chemical tag that was incorporated into the DNA of stem cells that allowed them to track where stem cells traveled and what types of cells they became. Scientists were able to follow the tags to the lizard's medial cortex -- an oft-studied analog to the human brain's hippocampus -- where they witnessed the generation of new brain cells. "The findings indicate that gecko brains are constantly renewing brain cells, something that humans are notoriously bad at doi...
16 killed in Mother's Day marches across Nicaragua as calls for new elections grow

16 killed in Mother's Day marches across Nicaragua as calls for new elections grow

World
MANAGUA, May 31 (UPI) -- At least 16 people died during protest marches on Nicaragua's Mother's Day in several cities across the country hours after business leaders called for new elections. Organizers planned the marches, called "Mothers of April," to protest the more than 70 people allegedly killed by police and pro-government gangs during protests in April against President Daniel Ortega's plan to raise social security taxes and cut benefits, human rights advocates said. That plan was shelved, but the protests grew into a movement against state violence and Ortega himself. Wednesday's marches were a continuation of these protests -- but resulted in more deaths as demonstrators came under attack by armed gunmen. The Nicaraguan Center for Human Rights -- also identified as CENIDH using...
Inditrade Group looks to grow inorganically

Inditrade Group looks to grow inorganically

Finance
Kolkata: Inditrade Group is actively working on the acquisition plans to grow faster and is looking to raise about Rs 200 crore to expand its different business units. The group plans to grow aggressively to raise stakes among the micro and small borrowers. The capital will be raised in a combination of equity and debt, group chairman Sudip Bandyopadhyay told ET. “We will continue to actively look for both organic and inorganic growth to grow rapidly,” Bandyopadhyay said. However, Inditrade Capital’s attempt to acquire a majority stake in microfinance firm Varam Capital has fallen flat as negotiations failed. Inditrade Capital floated Inditrade Microfinance as its wholly owned subsidiary in April last year. Bandyopadhyay said that Inditrade Capital’s non-banking un...
Miniature human brain implants survive, grow inside mice for months

Miniature human brain implants survive, grow inside mice for months

Science
April 16 (UPI) -- Miniature human brains, or human brain organoids, can survive and grow after being implanted in the skulls of mice. It's the first time human cerebral organoids have been installed inside another species.Researchers describe the breakthrough in a new paper published Monday in the journal Nature Biotechnology.Scientists grew the pea-sized brains from stem cells and then placed them inside the skulls of mice. Researchers removed a small amount of tissue to make room for the miniature brains. Tiny, transparent windows in the skulls of the test mice allowed scientists to keep tabs on the brain implants -- the organoids were also designed to express a green fluorescent protein, causing them to glow inside the mice skulls.Roughly 80 percent of the implants were successfully rec...
Researchers grow skin, with hair, from stem cells

Researchers grow skin, with hair, from stem cells

Health
Jan. 5 (UPI) -- In a first, stem cell researchers can grow hair follicles in skin, an Indiana University School of Medicine report said.The research, published this week in the medical journal Cell Reports, is the first demonstration that hair can be grown in laboratory-made skin, a difficult undertaking."The skin is a complex organ that has been difficult to fully recreate and maintain in culture for research purposes," Dr. Karl Koehler, an assistant professor of otolaryngology-head and neck surgery at Indiana, said in a press release. "Our study shows how to encourage hair development from lab grown mouse skin, which has been particularly troublesome for researchers to recreate in culture."The discovery came during development of a technique to make inner ear tissue from stem cells.
