# s-brain-behav: audiovisual cues vs increased risky choice in rats during gambling

<<  We used a rodent analog of the Iowa Gambling Task to determine whether the addition of audiovisual cues would affect choice preferences. Adding reward-concurrent cues significantly increased risky choice. This is the first clear demonstration that reward-paired cues can bias cost/ benefit decision making against a subject's best interests in a manner concordant with elevated addiction susceptibility >>

<< Mimicker Alarm. A Microsoft Garage Project. Wake up, Stay up. Set your alarm.Act when you hear it.Play a game to dismiss >>

<< Mimicker Alarm is a morning alarm clock app that helps you get up and stay up by playing a simple game, called a "Mimic". To dismiss your alarm, we might ask you to snap a selfie, speak a phrase, or even get out of bed! The Mimics require you to be alert, smart, and use yourself and your surroundings. Watch out - if you don't finish the game in time, we'll assume you've fallen back asleep and your alarm will start ringing again >>

# s-acad: more 'soft' sci res, more stat positive (true H1 alternative hypothesis) results

<< This study analysed 2434 papers published in all disciplines and that declared to have tested a hypothesis. It was determined how many papers reported a “positive” (full or partial) or “negative” support for the tested hypothesis. If the hierarchy hypothesis is correct, then researchers in “softer” sciences should have fewer constraints to their conscious and unconscious biases, and therefore report more positive outcomes. Results confirmed the predictions at all levels considered: discipline, domain and methodology broadly defined >>

<< If you've ever blown up a balloon or pulled at a pair of pantyhose, you may have noticed that the more the material stretches, the more transparent it becomes. It's a simple enough observation: the thinner a material, the more light shines through >>

<< For buildings and windows that automatically react to light, you don't have to spend as much on heating and air conditioning (..) The problem is, these materials are too expensive to produce for every window in a building. Our idea was to look for a simpler and cheaper way to let through more or less light, by stretching a very simple material: a transparent polymer that is readily available >>

# s-gst: periodic stripes: spacing and orientation

<< Patterning of periodic stripes during development requires mechanisms to control both stripe spacing and orientation. A number of models can explain how stripe spacing is controlled, including molecular mechanisms, such as Turing’s reaction-diffusion model, as well as cell-based and mechanical mechanisms >>

The Hiscock and Megason's  master model << predicts three main perturbations that can affect how stripes orient: one is a change in "production gradient," which would be a substance that amplifies stripe pattern density; second is a change in "parameter gradient," a substance that changes one of the parameters involved in forming the stripe; and the last is a physical change in the direction of the molecular, cellular, or mechanical origin of the stripe >>
