| How much sleep do you really need, and what happens when you don’t get enough? Posted: 01 Mar 2016 02:50 PM PST Every March, we are all faced with the arrival of Daylight Saving Time and its impact on our circadian rhythms, our sleep-wake pattern. The 1-hour shift in time can even temporarily disrupt our ability to fall asleep at night and to wake up in the morning. We not only lose an hour of sleep, but the time change disrupts the body's biological clock and circadian rhythm. The effect is the same as jetlag in plane travel, in which our bodies remain on the prior schedule for a period of time. |
| A new way to stretch DNA Posted: 01 Mar 2016 02:50 PM PST Researchers have recently developed a new way to controllably manipulate materials, in this case biomolecules that are too small to see with the naked eye.

This understanding could shed light on diseases like cancer and ALS. The new technique is called acoustic force spectroscopy (AFS). |

| Why objects in the universe have such a range of sizes: Celestial bodies born like cracking paint Posted: 01 Mar 2016 02:39 PM PST Researchers have explained why objects in the universe come in a wide variety of sizes, from the largest stars to the smallest asteroids -- and it has a lot to do with how paint cracks when it dries. When a volume is under internal tension -- as the early universe was due to gravity -- the most efficient way to relieve that tension is by 'cracking' hierarchically -- few large and many small. |

| Less connectivity improves innovation Posted: 01 Mar 2016 11:48 AM PST Connectivity does not always lead to more complex technology. An individual's propensity to learn from successful cultural models -- a common strategy that allows us to copy efficient solutions from others -- reduces the diversity of solutions. Partially connected groups are more likely to produce diverse solutions, allowing them to innovate by combining different solutions. |
| The evolution of amyloid toxicity in Alzheimer's Posted: 01 Mar 2016 11:47 AM PST Outsized human suffering is linked to 'amyloid beta,' an otherwise tiny, innocuous-looking protein molecule, as it is suspected to be a key player in neurodegenerative mechanisms underlying Alzheimer's disease. The molecules appear to become toxic within our bodies when they make contact with each other and form small bundles. Oddly, they may become less toxic again as the bundles grow and form ordered fibrillary plaque deposits. This begs the question: what's different about these bundles? |
| Eliminating GMOs would take toll on environment, economies Posted: 01 Mar 2016 10:15 AM PST Higher food prices, a significant boost in greenhouse gas emissions due to land use change and major loss of forest and pasture land would be some results if genetically modified organisms in the United States were banned, according to a study. |
