Human Body Lesson for Kids. Taste of Cinema. The Zeitgeist Movement Global. Eye Cells Inkjet-Printed for First Time. Using an inkjet printer, researchers have succeeded in printing adult eye cells for the first time.
The demonstration is a step toward producing tissue implants that could cure some types of blindness. Scientists have previously printed embryonic stem cells and other immature cells. But scientists had thought adult cells might be too fragile to print. Now, researchers have printed cells from the optic nerves of rats, finding the cells not only survived, but also retained the ability to grow and develop. Why Can't Humans Regenerate Body Parts? The loss of nerve cells in the retina causes many eye diseases that lead to blindness, said Dr. Martin and his colleagues separated retinal ganglion cells (which transmit signals from the eye to the brain) and glial cells (which provide support and protection for neurons) from the retinal tissue of adult rats. 3-D Printed Body Parts, Finally! Future Rx: Marijuana without the forgetfulness.
Marijuana's negative effects on memory are well known.
But now scientists have pinpointed where in the brain the drug causes this forgetfulness, and it's separate from where pot exerts its medicinal effects. Iain McGilchrist: The divided brain. 7 Scientifically Proven Ways To Grow New Brain Cells, Neurogenesis. Neurogenesis - “The birth of new neurons in the brain; also referred to as the process in which neurons are created.”The growth of new brain cells occurs in the region of the brain called the “hippocampus.”
The ‘hippocampus’ is an area involved with memory, learning, and other cognitive functions. In order to live and become part of our brain, new neurons formed in the hippocampus-region need support from surrounding nutrients from blood and glial cells. Most importantly, they need support from other surrounding neurons – otherwise these new brain cells will die. Though thousands of new brain cells are formed and produced via the hippocampus each and every day, many die quickly after birth.

9 Overlooked Technologies That Could Transform The World. What I've noticed is that most people don't really pay attention to "science" news, unless it's something that they can see immediately.
I think this is at least partially because of the amount of news that comes out daily - whatever we may think about the quality of news, there is just a flood of it, which makes picking out "interesting" items difficult. When I talk about (just for example) the idea of gene therapy, most people think that it is still complete science fiction, as opposed to a very near-term product that will be available. Of course, CSP has been around for years, so it isn't really "new" to the average person.

University of South Carolina researchers convert T-shirt into energy storage medium - Images. The researchers used a standard T-shirt purchased from a local discount store for their work Image Gallery (8 images) As manufacturers of smartphones and mobile devices strive to make their products increasingly portable, they repeatedly come up against the constraints of existing battery technology. However, Xiaodong Li, a professor at the University of South Carolina (USC) believes that we will soon be able to employ the clothes we wear to help overcome such challenges and to this end, Li has transformed T-shirt material into an energy storage medium which could one day be used to power portable devices.

Science In A Scoop: Making Liquid Nitrogen Ice Cream. Hide captionThe Smitten Ice Cream shop in the Hayes Valley of San Francisco serves fresh ice cream with one novel ingredient: liquid nitrogen.
The shop is located inside of a repurposed shipping container. Alan Greenblatt/NPR Robyn Sue Fisher's ice cream shop, Smitten, in San Francisco's Hayes Valley, may at moments resemble a high school chemistry lab, but that's because Fisher uses liquid nitrogen to freeze her product. Nitrogen is "a natural element," she notes. "It's all around us. " What makes it essential to Smitten is the ability to make ice cream fresh to order. Because servings are made on the spot, each one requires just a few ingredients. The mint chip, for example, contains just organic cream and milk, mint and a dash of salt. "This is the best ice cream I ever had," says my son, who is only 7 but already an experienced ice cream taster, as he spoons his way through an order of chocolate.
