    Plants and memory... Wow!

    A small team of researchers with Australian National University Canberra, has found evidence that suggests that plants are able to reset a memory that has not been proven to be useful, in essence, forgetting things after they have been stored.

    how we know things

    Leslie Lemke and Alonzo Clemons are mentioned in the first article but I hadn't heard of either so I looked them up and was stunned. If I hadn't read the the first article I would never have understood the implications of Lemke and Clemons. Here's two 20~ minute reads from Scientific American, the first is about what all of our minds seem to know from the beginning. In the case of Lemke the author argues he did not learn music, he already knew it because it was factory installed. The same with Clemons and his ability to quickly and accurately sculpt a 3D animal in clay after just a few seconds of looking at a 2 dimensional picture, the genius was already there. The second article is about how behaviors may be passed down a family line genetically.

    Genetic Memory: How We Know Things We Never Learned ...
    The baby does not learn trigonometry, but knows it; does not learn how to distinguish figure from ground, but knows it; does not need to learn, but knows, that when one object with mass hits another, it will move the object … ... As soon as the brain is built, it starts to express what it knows, what it comes with from the factory. And the brain comes loaded.

    Fearful Memories Passed Down to Mouse Descendants

    Kerry Ressler, a neurobiologist and psychiatrist at Emory University in Atlanta, Georgia, and a co-author of the latest study, became interested in epigenetic inheritance after working with poor people living in inner cities, where cycles of drug addiction, neuropsychiatric illness and other problems often seem to recur in parents and their children. “There are a lot of anecdotes to suggest that there’s intergenerational transfer of risk, and that it’s hard to break that cycle,” he says.

      this makes some sense to me....especially the second article on inherited transfer of risk, smells avoidance etc. after all most all of us are born with a sense of smell and taste, that we like certain smells, dislike other is born into us, and therefore must come from genetic transfer in some manner. I also believe that certain actions or ways of dealing with outside stress can and is transferred via genetic routes. That though can be broken, as most of these inborn things can be...changed. it is a matter of desire and force of will.

        It's something that plant lovers have long suspected, but now Australian scientists have found evidence that plants really can feel when we're touching them.
        Not only that, but different sensations trigger a cascade of physiological and genetic changes, depending on the stimulation the plants are receiving, whether it's a few drops of rain, or a little soft pat.

          July 2016 Was Officially The Hottest Month Ever On Record

          We have been reporting that the rising global temperature is breaking records month on month for almost a year now, but July 2016 has just taken the crown. Not only is it the warmest July since records began, it is the absolute warmest month ever recorded since 1880. And the record-smashing trend currently shows no sign of slowing.

          The latest figures to have been released by NASA show that the month of July was a full 0.84°C (1.51°F) above average for the month, but more concerning than that is that last month was also the hottest ever on record, shattering the last record by a toasty 0.11°C (0.2°F). This warming has continued despite the recent El Niño – which is thought to have boosted the past year's average temperatures on top of the rise caused by man-made climate change – having already passed its peak.

            That is odd. Yeah was warm here in July but far from records here..1980 was a record breaker HOT summer in Texas. The last few days here we have been rainy and mostly 10 degrees Fahrenheit below normal..forecast is for below normal Temps by 10 degrees for next 10 days.

            I believe world climate changes on large scale over big hunks of ages, and reverses

              Yeah.. we also have had a quite shitty summer this year.. rain rain and rain, kinda like the monsun.

                Physicists confirm possible discovery of fifth force of nature

                Recent findings indicating the possible discovery of a previously unknown subatomic particle may be evidence of a fifth fundamental force of nature, according to a paper published in the journal Physical Review Letters by theoretical physicists at the University of California, Irvine.

                "If true, it's revolutionary," said Jonathan Feng, professor of physics & astronomy. "For decades, we've known of four fundamental forces: gravitation, electromagnetism, and the strong and weak nuclear forces. If confirmed by further experiments, this discovery of a possible fifth force would completely change our understanding of the universe, with consequences for the unification of forces and dark matter."

                The UCI researchers came upon a mid-2015 study by experimental nuclear physicists at the Hungarian Academy of Sciences who were searching for "dark photons," particles that would signify unseen dark matter, which physicists say makes up about 85 percent of the universe's mass. The Hungarians' work uncovered a radioactive decay anomaly that points to the existence of a light particle just 30 times heavier than an electron.

                  Finnish genome has been known into something extraordinary, but until now it is known that the Finnish population in Europe is a totally unique case. The Finns are genetically so different from other Europeans that they need to be classified as their own people, the sum of the University of Eastern Finland Research Newsletter.
                  - It is quite correct to say that the Finns are not Europeans, when they do not resemble genetically other Europeans. But the Finns are not Asian either, they do not resemble any of them. Finns do not genetically resemble anyone.

                      Yes.. they are strange.

                        And add to it the ice age. We have a genetically unique people, who appeared to Finland earliest in 9000BC, ex nihilo. Weird shit.

                          When i was a university we did a ecology subject and assignment where i selected the hypothesis that Casuarina trees (i think it was them) in the forest around the univsersity had seeds which only sprouted after fire. I thought that was pretty stupid, but given typical growth rates there was a clear distinction between the tree heights and years since fire.

                          I wonder if the research above would apply to trees which only germinate after fire.

                            It is fascinating, that there is a whole range of species in the very specialized evolutional niche of taking advantage of the naturally occuring fire.

                              Scientists to Resurrect Woolly Mammoths.......


                              The idea of de-extinction or resurrecting extinct animals have been classified to be fiction in the previous years. However, the high-paced advancement of science and technology is now making the once-thought-to-be-impossible feat to be within reach.

                              University research labs and non-governmental have already started on projects that could bring back extinct animals. Furthermore, the International Conservation of Nature has also issued its first set of guidelines on resurrecting extinct species.
