Neuroscape Lab
Neuroscape Lab visualizes live brain functions using dramatic images March 17, 2014 [image: GlassBrain (credit: UCSF)] UC San Francisco neuroscientist Adam Gazzaley, MD, PhD, is hoping to paint a fuller picture of what is happening in the minds and bodies of those suffering from brain disease with his new lab, Neuroscape, which bridges the worlds of neuroscience and high-tech. Gazzaley aims to eliminate the need to immobilize subjects inside big, noisy … more…
one trillion odors
Humans can distinguish at least one trillion different odorsMarch 25, 2014 *[+]*[image: Discriminable sensory qualities] Howard Hughes Medical Institute(HHMI) scientists have tested the olfactory capacity of human volunteers and found that humans are capable of discriminating at least one trillion different odors — not just 10,000 different odors, a number first proposed decades ago and not backed by data. HHMI investigator Leslie Vosshall, who studies olfaction at the Rockefeller University, and Andreas Keller, a senior… read more *Topics:* Biotech

A zoomable 360-degree view of our galaxyMarch 25, 2014 *[+]*[image: Milky-Way---featured] NASA’s new zoomable, 360-degree mosaic, presented Thursday at the TED 2014 Conference in Vancouver, allows for exploring the Milky Way interactively. The panorama of our galaxy is constructed from more than 2 million infrared snapshots taken over the past 10 years by NASA’s Spitzer Space Telescope. The 20-gigapixel mosaic uses Microsoft’s WorldWide Telescope visualization platform. It captures about three percent of our sky, but because it… read more *Topics:* Physics/Cosmology
Genes' roles
MRI technique reveals genes’ roles in learning and memory Viewing brain activity at the molecule level March 26, 2014 *[+]*[image: mri_contrast_protein] MIT bioengineers have adapted MRI to visualize gene activity inside the brains of living animals. Tracking these genes with MRI would enable scientists to learn more about how the genes control processes such as forming memories and learning new skills, saysAlan Jasanoff, an MIT associate professor of biological engineering and leader of the research team. “The dream of molecular imaging is to provide…read more *Topics:* Biotech | Cogni... mais »

Genoma atlas
First comprehensive atlas of human gene activity releasedMarch 28, 2014 *[+]* Samples profiled in FANTOM5 (credit: Alistair R. R. Forrest et al./*Nature*) A large international consortium of researchers has produced the first comprehensive, detailed map of the way genes work across the major cells and tissues of the human body. The findings describe the complex networks that govern gene activity, and the new information could play a crucial role in identifying the genes involved with disease. “Now, for the first time, we are able to pinpoint the regions of the genome that can be active... mais »
