Lucid dreaming is a learnable skill, according to new research. Researchers have found that a specific combination of techniques will increase people’s chances of having lucid dreams, in which the dreamer is aware they’re dreaming while it’s still happening and can control the experience.

Researchers compared 20 veterans who had attempted suicide with 20 similar veterans who had not. Those who attempted suicide exhibited different patterns of gene expression, hinting at the existence of biological markers that could predict which patients may attempt suicide.

Research finds that certain small RNA molecules can trigger a mechanism hidden in every cell that forces it to self-destruct. This failsafe may protect us from cancer. The mechanism could potentially become a novel form of cancer therapy, the study authors say.

Plasma technology could hold the key to creating a sustainable oxygen supply on Mars, a new study has found. It suggests that Mars, with its 96% carbon dioxide atmosphere, has nearly ideal conditions for creating oxygen from CO2 through a process known as decomposition.

A significant number of childhood cancer survivors are worried about keeping their health insurance, to the point of letting it affect their career decisions, finds national cancer survey published in JAMA Oncology.

Snakes and spiders evoke fear and disgust in many people. There has been debate about whether this aversion is innate or learnt. Scientists discovered that babies as young as six months old feel stressed when seeing these creatures, long before they could have learnt this reaction.

Migraines may be brain’s way of dealing with oxidative stress. Migraines affect approximately 14 percent of the world's population, or 1.04 billion people. In the United States alone, migraine causes an estimated $36 billion annually in lost productivity, including 113 million lost work days.

Stanford scholars have probed how Americans think about mental life. Most people don’t have answers to the big questions about consciousness or the meaning of life, but they do have a way of thinking about and categorizing mental life. It comes down to three things – body, heart and mind.

Crows share an interesting set of behaviors with humans: they like to play, and they often use tools. Scientists investigate why crows are so playful, and found that the birds who played with tools in an experiment were much better at using those tools in a food-finding task.

Restaurants are reducing sodium in some newer menu items, but when it comes to existing fare and use of sodium overall there has been little change. Experts determined that a 1200mg drop in daily sodium intake could save as many as 92,000 lives and up to $25 million in annual health care costs

Fossil teeth discovery in Germany could re-write human history- "Their characteristics resemble African finds that are four to five million years younger than the fossils excavated in Eppelsheim. This is a tremendous stroke of luck, but also a great mystery."

Dogs really can smell your fear, and then they get scared too - Dogs exposed to sweat from human volunteers who watched videos designed to cause fear showed more signs of stress than those exposed to happy or neutral smells. They also had higher heart rates, and sought reassurance from owners.

The use of electroconvulsive therapy (ECT) to treat serious mental health problems is more prevalent in women and older individuals, researchers have found in an audit of ECT in England from 2011–2015.

Even small amounts of oil made birds near Deepwater Horizon sick. Findings could not be published until now because they were used in the legal settlement that was finalized last year, in which the oil company BP was ordered to pay $8.8 billion for restoration efforts.

Suicide rates are higher in rural areas than urban areas, according to a recent report from the CDC. The same is true for opioid related overdoses and deaths, suggesting rural areas are lacking the support services and treatment needed to curb epidemics.

20 j938920 Are there any firewalls in place if you happen to find dormant microbacterial life on an asteroid?
16 tkoclubs What an exciting time to be alive! I actually have three questions. 1) What are some of the main differences and similarities between the OSIRIS-REx and the past ESA Rosetta mission? Besides sample return. 2) Can you explain how your sample collection device works, and why this design was chosen. 3) If you were to build a cube sat (1U to 3U) today that launches in 2-3 years what type of science mission would you place on it? Thank you for taking time to reach out.
11 Shiderme I understand that Bennu is both a time capsule of sorts, and accessible. But was Bennu chosen because of its relative accessibility, or because what we know about it makes us feel it is more likely than other asteroids to harbor organic material from long ago?
8 gavinozzo If it takes 1 year to reach Bannu and if the OSIRIS-REx will be back on 2023, does it means it collects samples for 4 years?
8 SelectAll_Delete What would be the most exciting or unexpected thing to find on Bennu?
14 asbruckman Thanks for coming to talk with us today! So much of software development in regular business is a 'trial and error' sort of a thing--which is obviously a just terrible idea for a spacecraft. :) . Can you tell us about your software engineering practices? Do you patch code after launch? Have you ever fixed a serious software error after launch?
7 Shock1217 What do you anticipate to be the most challenging part of the planned mission for OSIRIS-REx?
8 LilooWoo I've read that asteroids can be composed of precious metals like gold, silver and platinum. What are the chances that Bennu will be made of precious metals?
8 noobhedz Hey guys! Thank you for taking the time to answer some of our questions. My question to all of you is, as a college student pursuing a degree in computational mathematics what advice do you have regarding getting a job in your field! What types of things should I be doing to improve my chances that a company like nasa would consider hiring me? Thank you in advance!

5 Archer2408 OSIRIS-REx is an interesting name. Is it some sort of acronym? I'd love to hear the origin or inspiration behind naming it.
6 praveerk Is anyone working on the telemetry for this mission actively looking for any signs of the [flyby anomaly] (https://en.m.wikipedia.org/wiki/Flyby_anomaly)that has been observed in some previous Earth flybys?
4 jsf84 Hi All! Super big fan of what you are doing, I was in the NASA Robotics Mining Competition in May of 2016 where our team of engineers had to design a regolith mining robot so I am somewhat familiar with the overall concept of what you are going to achieve. My question is, what method of mining will you use to take samples of the regolith to bring back to earth? At the competition I saw everything from scoops, augers, conveyor belts, etc. and the conveyor belt system appeared to do best during competition. Thank you!!
21 smallatom Be honest, did you guys ever use Kerbal Space Program for anything related to this mission?
3 Skanky How much of an increase in speed are we talking about here?
6 lezkerr What is this thing called "Regolith" ?
6 johnthebutcher Bennu was targeted because of a confluence of various factors (size, composition, Δv/$/time budgets). If you could launch another OSIRIS-REx in the next launch window without worrying about so many of these constraints, what would be the next most interesting target for this sort of investigation in our solar system and why?
