| Posted: 29 May 2019 04:00 AM PDT I am Jamil Zaki, a professor of psychology at Stanford University and the director of the Stanford Social Neuroscience Lab. I wrote a book called The War for Kindness (it comes out next week on June 4), which shares stories and research about how to fight for empathy even when it feels impossible to some days. Empathy is in short supply. Isolation and tribalism are rampant. We struggle to understand people who aren't like us, but find it easy to hate them. Studies show that we are less caring than we were even thirty years ago. In 2006, Barack Obama said that the United States is suffering from an "empathy deficit". Since then, things only seem to have gotten worse. It doesn't have to be this way. In my book, I share my research, including experiments from my own lab, showing that empathy is not a fixed trait - something we're born with or not - but rather a skill that can be strengthened through effort. There are stories of people who embody this new perspective, fighting for kindness in the most difficult of circumstances. We meet a former neo-Nazi who is now helping extract people from hate groups, ex-prisoners discussing novels with the judge who sentenced them, Washington police officers changing their culture to decrease violence among their ranks, and NICU nurses fine-tuning their empathy so that they don't succumb to burnout.

| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 29 May 2019 08:12 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| How does a simple circuit with a cell and a bulb actually work in detail? Posted: 29 May 2019 02:39 AM PDT I want to know the inner workings of a simple electric circuit. I have been getting confused lately regarding charge carriers and what not. [link] [comments]  |
| Why is mars's axial tilt similar to earth's? Posted: 29 May 2019 02:39 AM PDT As I understand it, the spin of mars is similar to earth's because it is derived from the initial spin of the accretion disc. But what factors influence the axial tilt of a planet? As I understand it, for a moonless ( large ones ) planets this varies wildly because nothing keeps it in place. Why are earth's and mars's axial tilts so similar, and if by chance, what are the odds? [link] [comments]  |
| How do protons become converted into neutrons and vice versa? Posted: 29 May 2019 07:40 AM PDT I saw in another thread about the number of protons vs electrons vs neutrons in the universe and someone mentioned that neutrons and protons could be converted into each other through the weak force. How does this process take place? The other thread this came from: https://www.reddit.com/r/askscience/comments/bu7j1j/are_there_more_protons_neutrons_or_electrons_in/ [link] [comments]  |
| How do transformers deal with different input potential differences? Posted: 29 May 2019 07:05 AM PDT I think I have a decent understanding of how a transformer works, that by altering the number of loops on the primary and secondary coils you can step up or step down the output potential difference. One thing I'm not sure about is how the transformers in things such as laptop cables allow an input P.D. range from 110V to 240V and still output the 12V required by the laptop. Can anyone explain this to me please? [link] [comments]  |
| Is the ground getting "taller"? Posted: 28 May 2019 07:08 PM PDT I've been reading about archeology lately and find it interesting that they always have to dig to find things. Are objects on the ground constantly being covered in layer after layer of dirt? Is the ground getting "taller" so to speak? Where is this dirt coming from? I understand, in some cases, humans built new cities on top of the ruins of old cities. Bonus question: Would this slightly offset sea level rise or is it just dirt moving from mountains to valleys?

| How do we measure someone's olfactory response? Posted: 29 May 2019 06:10 AM PDT I know there is variance in the ability to smell between different individuals, such as those with hyperosmia/hyposmia, but how is this determined? Is there a specific scale or measurement that is used? [link] [comments]  |

| Why do some chemicals react differently when added in a different way? Such as Chlorine, and Water. Posted: 29 May 2019 05:42 AM PDT Why do chemical such as Chlorine act differently when added to water, if water is added to it? Chlorine when added to water reacts differently, than if you were to put water onto chlorine, why is this? [link] [comments]  |
| How do genes influence the development of beaks in birds? Posted: 29 May 2019 02:45 AM PDT Is there a major underlying genetic mechanism underneath that shapes the beaks of all birds? I find it fascinating as beaks are so varied and I'm wondering how the genetic mechanism functions to create this diversity amongst bird beaks. If you don't have an answer, are there any resources worth looking at? Any other directions I can head in? [link] [comments]  |
| Do strategic skills transfer between different games? Posted: 28 May 2019 01:34 PM PDT If I play a lot of chess will I be better at go, or if I play a lot of strategy video games will it help (to whatever extent) with board games like Risk etc. or since these games have different rules, would the skills for them be mostly independent from each other? [link] [comments]  |
| Posted: 29 May 2019 02:32 AM PDT In this article there is a good picture showing the single layers of such a "liquid packaging board". Why do the layers not just simply separate where there is AL? As I understand it, Al is vaporized onto a PE - layer, which ist hen merged with another PE layer. But in my experience introduction of an Al-Layer inbetween other layers will prevent any kind of adhesion of those outer layers to each other, meaning you could easily pull those apart. I hope you understand what I'm trying to say... [link] [comments]  |
| Is there a theoretical max diameter for hail? Posted: 28 May 2019 09:58 PM PDT With some of the footage that has been going around of the weather in the mid west, I see a lot of people sharing stories of baseball, from one thread I saw some even telling tall tales of basketball sized hail. This has me wondering, is there a limit to how large an individual piece of hail can get before hitting the ground? If so, what determines that? [link] [comments]  |
| How does 'activated charcoal' work in the body? Are there any ways of amplifying it's powers? Posted: 29 May 2019 12:59 AM PDT |
| On the molecular level, what makes an oil classified that way? Posted: 28 May 2019 06:47 PM PDT I have an add-on question to that if anyone is willing to take a stab: If you had unusual elements that were to reach their liquid state, would that liquid state be classified as an oil? [link] [comments]  |
| Posted: 28 May 2019 11:13 PM PDT EDIT: Also, in a lightning strike, it is said that positive charges travel from the ground up and negative charges travel from the cloud down. When they meet, this causes a lighting bolt. My additional question is: How can "positive charges" move? Aren't positive charges (protons) much less mobile than negative charges (electrons) ? EDIT: Question #3: When a lightning strikes the ground, the negative charges moves from the bottom part of the cloud to the ground. What happens to the top part of the cloud, which is positively charged? [link] [comments]  |

| Can viral vectors used in gene therapy replicate, or do they just deliver their payloads and die? Posted: 28 May 2019 01:59 PM PDT I've read about experiments in curing genetic diseases using viral vectors. From what I understand, they take a virus, put RNA or DNA encoding correct genes, as opposed to faulty ones causing patient's disease, then infect people with that virus, and it injects patient's cells with correct genes. What I want to know is, since viruses use cells to make more viruses, are these viral vectors capable of making more of themselves, or they just deliver their payload and die? Meaning that during therapy, you only get as much viral particles as there is in the shot you're given, or however it's administered? [link] [comments]  |
