NASA links nanobacteria to kidney stones and other diseases

...ronauts. With the potential for future exploratory space missions to the moon and Mars, longer missions, an...a bioreactor chamber which simulates conditions of space travel. In this microgravity environment, NB was found to multiply five times faster compared to nor...

Ophthalmologists implant five patients with artificial silicon retina microchip

...ye. According to Chow, "The use of the subretinal space to hold a device that artificially stimulates the retina seems a logical step in replacing the loss of photoreceptor cells of the retina. If the implant is tolerated well and is able to successfully stimulate the retina, it may open up new opportunit...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...larger than phospholipids, so that there is enough space for the fluorophores, which are larger than the average molecule that is found inside cell membranes," said Hammer, professor and chair of the Department of Bioengineering at Penn's School of Engineering and Applied Sciences. " Another feature that m...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

...said Edwin Waddington, a UW professor of Earth and space sciences. Like water on a hillside, Siple Dome ice flows down into adjacent ice streams, where it continues to the nearby Ross Ice Shelf, a part of a bay on the Ross Sea that is covered with floating glacier ice. "Then the whole thing spreads out l...

Open microfluidic and nanofluidic systems

...s. Other applications include customized chips for space travel in order to monitor microbes inside spacecraft or to detect life on other planets. An obvious prerequisite for such miniaturized labs are appropriate microcompartments for the confinement of very small amounts of liquids and chemical reagents...

New research questions basic tenet of neuron function

... and release them when needed into the synapse, or space between nerve cells, where the chemical signal is transmitted to other neurons. It is known that synaptic vesicles release their neurotransmitters in two different "modes" ?one when the neuron is stimulated and actively relaying a message, and the o...

The secret lives of whales

...inging, he can fix its location and position it in space and time and observe multiple animals that are 100’s of miles apart—cohorts of humpback singers moving coherently?and watch the collective migration of species over large portions of an ocean basin. “So if I am a whale off Newfoundland, I can hear a ...
