What Is Light, Anyway?

First you're taught that light is wave. Then you get a little older and your teacher explains that it's actually particles called photons. Wait, which is it then? Particles? Waves? Both? Neither? This video should help explain. More »

Vegan Options Portland State University

Please add more vegan options at PSU!

Dear?

Vegan foods are more popular than ever at schools nationwide, including here at PSU. As a student on campus, I am hoping to see more delicious, cruelty-free foods offered. With schools across the country such as the University of California, San Diego and the University of North Texas opening all-vegan dining halls within the past year, the very least we could do is offer a wide range of vegan meals in every dining hall.

There are so many delicious and eco-friendly foods available nowadays, from faux-beef tacos to vegan pizza, and Portland State could be doing so much more to meet the growing demand. I urge you to work with students to implement these changes.

Sincerely,
[Your Name]

Synaptic molecule works differently than thought; may mean new targets for Alzheimer's

Feb. 19, 2013 ? In a pair of new papers, researchers at the University of California, San Diego School of Medicine and the Royal Netherlands Academy of Arts and Sciences upend a long-held view about the basic functioning of a key receptor molecule involved in signaling between neurons, and describe how a compound linked to Alzheimer's disease impacts that receptor and weakens synaptic connections between brain cells.

The findings are published in the Feb. 18 early edition of the Proceedings of the National Academy of Sciences.

Long the object of study, the NMDA receptor is located at neuronal synapses -- the multitudinous junctions where brain cells trade electrical and chemical messages. In particular, NMDA receptors are ion channels activated by glutamate, a major "excitatory" neurotransmitter associated with cognition, learning and memory.

"NMDA receptors are well known to allow the passage of calcium ions into cells and thereby trigger biochemical signaling," said principal investigator Roberto Malinow, MD, PhD professor of neurosciences at UC San Diego School of Medicine.

The new research, however, indicates that NMDA receptors can also operate independent of calcium ions. "It turns upside down a view held for decades regarding how NMDA receptors function," said Malinow, who holds the Shiley-Marcos Endowed Chair in Alzheimer's Disease Research in Honor of Dr. Leon Thal (a renowned UC San Diego Alzheimer's disease researcher who died in a single-engine airplane crash in 2007).

Specifically, Malinow and colleagues found that glutamate binding to the NMDA receptor caused conformational changes in the receptor that ultimately resulted in a weakened synapse and impaired brain function.

They also found that beta amyloid -- a peptide that comprises the neuron-killing plaques associated with Alzheimer's disease -- causes the NMDA receptor to undergo conformational changes that also lead to the weakening of synapses.

"These new findings overturn commonly held views regarding synapses and potentially identify new targets in the treatment of Alzheimer's disease," said Malinow.

Co-authors on both papers are Helmut W. Kessels, Center for Neural Circuits and Behavior, Departments of Neuroscience and Biology, UCSD and Netherlands Institute for Neuroscience, Royal Academy of Arts and Sciences; and Sadegh Nabavi, Center for Neural Circuits and Behavior, Departments of Neuroscience and Biology, UC San Diego.

The research was funded in part by the National Institutes of Health (grants MH049159 and AG032132), the Shiley-Marcos Foundation, the Cure Alzheimer's Foundation, and the Internationale Stichting Alzheimer Onderzoek.

Israeli Lunatic Sniper Instagrams a Photo of a Child in His Crosshairs

The Israeli Defense Forces has a history of overzealous campaigns on its official social media accounts. So maybe we shouldn't be surprised that an IDF sniper doesn't take his job very seriously. Or that's the impression we get, since he Instagrammed a photo of what appears to be a Palestinian child in the crosshairs of his rifle scope. Real, real messed up. More »

Opera Shrinks In-House Developer Team As It Prepares Shift To WebKit

Opera has been making a lot of headlines of late -- with last week's announcement of its big strategic shift to WebKit. Followed hard on the heels by the news of its $155m purchase of Skyfire. But the Norwegian software maker's decision to abandon its own web-rendering engine in favour of WebKit, has had another, less visible impact: it has reportedly dismantled a core in-house developer team.
