    it's like you said ilan... 'This is huge news!'
    I can imagine the amount of new study and new theroes this will bring now... I was trying to like of a witting comment and comparing this to some other thing (like the invention of the wheel or even the invention of the telescope)... but nothing compares to this.. wow !!
    Einstein is doing great ... lol

    11 Life Lessons from Albert Einstein
    Bobbi Klein, Lifehack

    Albert Einstein offered us more than just the amazing theory of relativity and E=mc2. Through his persistence in his discoveries in science, Einstein shined a light on how each of us can do the impossible by hard work, experiencing failure, and valuing people. Even if you are not a scientist, you can apply these life lessons to your life today.


    Simplicity

    If you can’t explain it to a six year old, you don’t understand it yourself.” – Albert Einstein

    The more complicated you have to make something seem, the more you do not understand the inner workings of it. Think about the best teachers that you have had in your life. Did they make even the most complicated topics full of vocabulary that you did not understand or did they make it easier to understand by simplifying?


    Creativity

    Creativity is contagious, pass it on.” – Albert Einstein

    Inspire others to do what they love. Use your creativity to create new works, and you never know what others will create. It’s time to let your mind create projects and ideas that will have a domino effect throughout the world.


    Hard Work and Failure

    The only sure way to avoid making mistakes is to have no new ideas.” – Albert Einstein

    You never fail until you stop trying.” - Albert Einstein

    Einstein spent most of his life working on physics theories- some never worked out and others we know today. You never know which one will work out, but persistence is key. You have to keep working hard and keep trying to solve your problem. Failure doesn’t exist until you stop trying.


    Live in the Present

    I never think of the future – it comes soon enough.” - Albert Einstein

    You are only guaranteed the moment that you have right now, at this moment. You can try to get yourself worried about the future and make plans that may not work out according to plan. What matters most is living now, today. Do your best right now and do not worry about tomorrow.


    Be Unconventional

    I never made one of my discoveries through the process of rational thinking.” – Albert Einstein

    Everything great took a process of going outside of the box and doing something unconventional. If you continue to do the norm, then you are going to just produce normal, conventional results. Think differently, and you may find your answer.


    Imagination

    Imagination is the highest form of research.” – Albert Einstein

    I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.” – Albert Einstein

    Imagination is key. When you imagine something differently, you begin to share with others. People begin to see the world that you imagine. Together you can create and help each other. Take time today to daydream, imagine, and share your ideas with others.


    Work Towards the Impossible

    Only those who attempt the absurd can achieve the impossible.” – Albert Einstein

    If it seems ridiculous to others and you are willing to take the risk, then you are able to achieve the impossible. When you go beyond what others think is reasonable, an amazing thing starts to happen. You complete what was once an obstacle.


    Value People

    We know from daily life that we exist for other people first of all, for whose smiles and well-being our own happiness depends.” – Albert Einstein

    Life isn’t worth living, unless it is lived for someone else.” – Albert Einstein

    If you put people first, they will value you and look to you as a person who genuinely cares about others. Spend at least a few minutes out of your busy day being fully engaged with people without any distractions. Show them that you value them. Thank them and send compliments their way. It will not only make their day better, but they will appreciate it and remember what you have done for them.


    Sharing

    Student is not a container you have to fill but a torch you have to light up.” – Albert Einstein

    Share your ideas with others. You may light a spark that ignites someone to do what they have always wanted. If you just hold all of your ideas and knowledge to yourself, you are not helping others at all. What if you held the key that would solve someone’s problems, wouldn’t you want to share it?


    Be Open to Learning

    Learning is experience. Everything else is just information.” - Albert Einstein

    It’s the journey as you learn and not just soaking up all of the information. It’s fully diving in and learning that some things work and others do not. Learning is not a one-size-fits-all path, but your own customized journey.


    Do What is Right

    Always do what’s right; this will gratify some and astonish the rest.” – Albert Einstein

    When you come to the fork in the road or if your consciousness is offering you a decision, always do what is right. You may feel that the other option will be easier or offer you more money, but when you know that the other option will allow you more opportunity in the future or is the right thing to do, then you have to do it. It’s not going out and choosing the easiest decision, but taking the time to follow your gut and do the right thing will keep you standing out from the crowd.

    Mercury Below Venus in Morning Sky
    Bruce McClure in TONIGHT | April 14, 2019



    No matter where you live, these next few mornings are a grand time to look for the elusive planet Mercury. For all of us, around the globe, Mercury is now below Venus – the brightest planet – in the sunrise direction, before daytime washes the pair from view. The morning of April 16, 2019, will present the closest pairing of Mercury and Venus in the morning sky for all of 2019. On that morning, these two worlds will be around 4 degrees (width of two fingers at arm’s length) apart on the sky’s dome. They’ll be close enough together to fit (or nearly fit) inside a single binocular field. So if you see Venus, but not Mercury, in the sky before sunrise, try aiming binoculars at Venus to view both planets in a single binocular field.

    For the Southern Hemisphere, April 2019 showcases Mercury’s best morning apparition for the year. The planet will be easily visible to the eye alone, below Venus before sunup. For the temperate and polar zones in the Northern Hemisphere, the view of Mercury in the morning sky isn’t as good. The planet is closer to the sunrise. Use binoculars to scan for it along the eastern horizon before sunup. Then remove the binoculars and try to see Mercury with the eye alone.

    From anywhere worldwide, it is to your advantage to find an unobstructed horizon in the direction of sunrise for your Mercury search. Look first for Venus – the third-brightest celestial body, after the sun and moon – to blaze mightily in your eastern sky. Then seek for Mercury a short hop below Venus. Keep in mind that Mercury follows Venus into the sky some 15 to 20 minutes after Venus first comes up. So if Venus is sitting very low in your predawn or dawn sky, chances are that Mercury has yet to rise.

    Venus’ rising time varies considerably around the world. At far-northern latitudes (such as Alaska), Venus and the sun rise at nearly the same time. From mid-northern latitudes – like the contiguous U.S., Europe and Japan – Venus rises roughly an hour before sunrise. At the Earth’s equator (0 degrees latitude) Venus rises nearly two hours before the sun; and from temperate latitudes in the Southern Hemisphere, Venus rises a whopping 2 1/2 hours before sunrise. Clearly, the southerly latitudes have the big advantage in catching Mercury.

    It was clear here today in the early morning; it was easy to see both Venus and Mercury in the eastern sky. - ilan

    Does a year in space make you older or younger?
    EarthSky Voices in HUMAN WORLD | April 16, 2019

    The NASA Twins study – featuring astronaut twins Scott and Mark Kelly – was the perfect space experiment. Scott spent a year in space aboard the International Space Station. Mark remained on Earth. The results?


    Are space twin Scott and Earth twin Mark no longer identical? Image via Robert Markowitz/NASA.

    Daily life aboard the International Space Station moves fast. Really fast. Traveling at approximately 17,000 miles per hour, 300 miles above the Earth, astronauts watch 16 sunrises and sunsets every “day” while floating around in a box with a handful of people they depend on for survival.

    One need look no further than Hollywood blockbusters like “The Martian,” “Gravity” and “Interstellar” for futuristic visions of life beyond Earth as we venture longer and deeper into outer space. But what about the human body’s response to real-life spaceflight – what are the health effects? Will space travelers age at different rates than those of us on Earth? Just how adaptable to the space environment are we?

    Certainly these are concerns for NASA. How space travel and long-duration missions might change the human body, and whether those changes are permanent or reversible once astronauts return to Earth, is largely unknown. The opportunity to explore these intriguing questions arose with identical twin astronauts Scott and Mark Kelly.

    In November of 2012, NASA selected astronaut Scott Kelly for its first one-year mission. At a press conference not long thereafter, it was Scott who hinted that that this mission might provide the chance to compare the impact of space living on his body with his Earth-dwelling identical twin brother, Mark Kelly, who had also been an astronaut and former Navy test pilot. Remarkably, the Kelly twins were individuals of similar “nature (genetics) and nurture (environment),” and so the perfect space experiment was conceived – featuring “space twin and Earth twin” as the stars. Scott would spend a year in space aboard the International Space Station, while his identical twin brother, Mark, would remain on Earth.

    The NASA Twins Study represents the most comprehensive view of the human body’s response to space flight ever conducted. Results will guide future studies and personalized approaches for evaluating health effects of individual astronauts for years to come.

    As a cancer biologist at Colorado State University I study the impact of radiation exposure on human cells. As part of the Twins Study, I was particularly interested in evaluating how the ends of the chromosomes, called telomeres, were altered by a year in space.

    Teasing apart health effects of space living

    NASA put out a call and selected 10 peer-reviewed investigations from around the country for the Twins Study. Studies included molecular, physiological and behavioral measures, and for the first time ever in astronauts, “omics”-based studies. Some teams evaluated the impact of space on the genome – the entire complement of DNA in a cell (genomics). Other teams examined which genes were turned on and producing a molecule called mRNA (transcriptomics). Some studies focused on how chemical modifications – which do not alter the DNA code – affected the regulation of the genes (epigenomics). Some researchers explored the proteins produced in the cells (proteomics), whereas others scrutinized the products of metabolism (metabolomics).

    There were also studies examining how the space environment might alter the microbiome – the collection of bacteria, viruses and fungi that live in and on our bodies. One investigation examined the immune response to the flu vaccine. Other teams searched Scott’s biological samples for biomarkers of atherosclerosis and upward fluid shifts in the body due to microgravity, which can affect vision and cause headaches. Cognitive performance was also evaluated using computer-run cognition tests specifically designed for astronauts.

    More than 300 biological samples – stool, urine and blood – were collected from the twins at multiple times before, during and after the one-year mission.

    The Kelly twins are without a doubt one of the most profiled pairs – on or off our planet. They are also one of the most interviewed. One question often asked is whether Scott will return from space younger than Mark – a situation reminiscent of “Interstellar” or Einstein’s so-called “ target=”_blank”Twin Paradox.” However, because the ISS is not traveling anywhere near the speed of light relative to us, time dilation – or the slowing of time due to motion – is very minimal. So any age difference between the brothers would only be a few milliseconds.

    Even so, the question of spaceflight-associated aging and the accompanying risk of developing age-related diseases like dementia, cardiovascular disease and cancer – during or after a mission – is an important one, and one that we aimed to address directly with our study of telomere length.

    Telomeres are the ends of chromosomes that protect them from damage and from “fraying” – much like the end of a shoestring. Telomeres are critical for maintaining chromosome and genome stability. However, telomeres naturally shorten as our cells divide, and so also as we age. The rate at which telomeres shorten over time is influenced by many factors, including oxidative stress and inflammation, nutrition, physical activity, psychological stresses and environmental exposures like air pollution, UV rays and ionizing radiation. Thus, telomere length reflects an individual’s genetics, experiences and exposures, and so are informative indicators of general health and aging.

    Telomeres and aging

    Our study proposed that the unique stresses and out-of-this-world exposures the astronauts experience during spaceflight – things like isolation, microgravity, high carbon dioxide levels and galactic cosmic rays – would accelerate telomere shortening and aging. To test this, we evaluated telomere length in blood samples received from both twins before, during and after the one-year mission.

    Scott and Mark started the study with relatively similar telomere lengths, which is consistent with a strong genetic component. Also as expected, the length of Earth-bound Mark’s telomeres was relatively stable over the course of the study. But much to our surprise, Scott’s telomeres were significantly longer at every time point and in every sample tested during spaceflight. That was exactly the opposite of what we expected.

    Furthermore, upon Scott’s return to Earth, telomere length shortened rapidly, then stabilized during the following months to near pre-flight averages. However, from the perspective of aging and risk of disease, he had many more short telomeres after spaceflight than he did before. Our challenge now is to figure out how and why such spaceflight specific shifts in telomere length dynamics are occurring.

    Our findings will have relevance to earthlings as well, since we all grow old and develop age-related conditions. These Twins Study results may provide new clues into the processes involved, and thereby improve our understanding of what we might do to avoid them or extend health span.

    The long-term health effects of long duration spaceflight are yet to be determined, but the TWINS Study represents a landmark step in humankind’s journey to the moon, Mars and beyond…and to making science fiction science fact.

    Another asteroid disintegrates over Russia
    Eddie Irizarry in HUMAN WORLD | SPACE | April 16, 2019

    A bright meteor was caught in many dashcam videos – in broad daylight – on April 6, 2019, over the Russian city of Krasnoyarsk. See a video compilation here.


    Once again, a space rock has been seen while disintegrating over Russia, this time over the industrial city of Krasnoyarsk, in the south-central region of that country. The video above, from the American Meteor Society (AMS), is a compilation of many dashcam videos captures of the meteor as it sped across the sky in broad daylight over Krasnoyarsk on April 6, 2019. Although the incoming asteroid that produced the meteor is estimated to have been small – about 3.2 to 6.5 feet wide (1 to 2 meters wide) according to calculations – video captures and reports from the International Meteor Organization (IMO) indicate it was very bright.

    The Siberian Times reported on April 7 that the meteor was:

    Bright and noisy with a long, sparkling green and yellow tail. It was filmed by multiple observers in Krasnoyarsk region … Some residents said the meteor was blindingly bright, akin to the light and sparks created during intense welding work. It split into several parts before disappearing in the sky somewhere over Irkutsk region, east of Krasnoyarsk.

    According to NASA, the small asteroid entered Earth’s atmosphere at 40,489 miles per hour (65,160 km/hour) or 11 miles per second (18.1 km/sec).

    This is the third bright meteor detected in or near Russia in the last few months. According to the IMO:

    Just recently, an asteroid hit the Earth over the Bering Sea (December 18, 2018) and another fireball was visible over the Krasnoyarsk region on March 15, 2019.

    Why so many meteors over Russia? About 70 percent of our planet is covered by water, which means a space rock entering Earth’s atmosphere has a 70 percent probability of disintegrating over an ocean. And indeed most of these events do occur over oceans or unpopulated areas, and thus go unnoticed. When an asteroid’s disintegration occurs over land, it can happen anywhere, but there is more probability over Russia given that it has Earth’s most extensive territory. At more than 6.6 million square miles (17 million square km), Russia is by far the largest country in the world.

    To date, there are no reports that fragments of the April 6, 2019, meteor have been found. However, if any did land, they came down close to the site of the Tunguska Event in 1908 when a meteor exploded in the atmosphere wiping out 80 million trees, with the estimated force of 185 Hiroshima bombs.
