...So then what exactly is causing the recent spate of pet illnesses and deaths? As a scientist I must initially conclude that there is not enough data to come to a firm conclusion. However, that does not mean that we cannot make well educated assumptions. Because melamine is not particularly toxic and is not known to cause kidney failure, it is logical to assume that there are other contaminants in pet food in addition to the melamine.
Obviously, Chinese farmers, chemical producers, and food additive distributors have no compunction against putting harmful or even toxic compounds into products that are to be consumed by either animals or humans. China has a history recently of putting business interests far ahead of human interests. Manufacturers in China have few restrictions on how they operate and whether or not they are permitted to pollute the air and water. Cancer rates have soared in many parts of China that have become industrialized. It has been noted by Western journalists that the smog is so thick in some Chinese cities in that you can stare at the sun without worry because it looks like a dim orange ball in the sky.
Another assumption that we can make based on what is known about toxicology is that it is not uncommon for two mildly toxic compounds to have a cumulative effect that is far more toxic than either compound alone. As such, it seems quite likely that other chemical contaminants originating in China, which have not yet been identified, are also present in Chinese food products. Melamine would almost certainly put a strain on the kidneys because it contains a great deal of nitrogen, and one of the major functions of the kidneys is to clear excess nitrogen from the body in the form of urea (present at high levels in the urine). If Chinese farmers and food product distributors have been putting other toxic compounds into their products for similar, nefarious reasons as they have been using melamine, then it seems quite possible that two or more mildly toxic compounds are having a synergistic effect in causing kidney damage, and eventually failure. ... more »

You may perhaps recall a lot of attention paid to methane from plants back in January 2006. A team of scientists (mostly from the Max Planck Institute for Nuclear Physics) reported in Nature that they had found evidence that plants release huge amounts of the gas--perhaps accounting for ten to thirty percent of all the methane found in the atmosphere. ...
Fast-forward eighteen months. A group of Dutch researchers put the Max Planck team's conclusions to the test by tracing radioactive carbon isotopes through plants. Their conclusion: "There is no evidence for substantial aerobic methane emission by terrestrial plants." ... more » Thursday, April 26

More than a quarter of the country’s 2.4 million bee colonies have been lost — tens of billions of bees, according to an estimate from the Apiary Inspectors of America, a national group that tracks beekeeping. So far, no one can say what is causing the bees to become disoriented and fail to return to their hives.
As with any great mystery, a number of theories have been posed, and many seem to researchers to be more science fiction than science. People have blamed genetically modified crops, cellular phone towers and high-voltage transmission lines for the disappearances. ... more » Wednesday, April 25

World-famous physicist Stephen Hawking experienced eight rounds of weightlessness during a better-than-expected airplane flight that he saw as the first step toward a trip in space.
"It was amazing," Hawking told reporters afterward, using his well-known computerized voice. "The zero-G part was wonderful, and the high-G part was no problem. I could have gone on and on. -- "Space, here I come," he said.Hawking's host, Zero Gravity Corp. co-founder and chief executive officer Peter Diamandis, said before the flight that he'd claim success if Hawking had just a single half-minute float in weightlessness aboard the company's specially modified Boeing 727 jet. Afterward, Diamandis and other fliers said Hawking took eight turns with ease. -- "He would have flown more if we let him," said Noah McMahon, one of Hawking's coaches as well as Zero Gravity's chief marketing officer. "He was all smiles all the time." ... more » Tuesday, April 24

Mysterious invisible "ghost spirals" observed in a nearby galaxy appear to be gigantic super-hot shockwaves, say astrophysicists. -- The ghostly spiral arms of galaxy M106 were first detected in radio waves, contain no stars, and do not match up with the curved starry arms of the galaxy as seen by telescopes in visible light.
But new observations of M106's "anomalous arms" confirm they are the result of two gigantic jets blasting at a strange angle from the galaxy's central supermassive black hole. -- "All you see is gas that is heated by shock waves," said astrophysicist Andrew Wilson of University of Maryland, referring to what the ghost arms are made of. ... more » Saturday, April 21

I will limit my concern to the interesting, provocative, and sometimes mystifying "semiotic turn" in some of the most recent science studies. Specifically, I have in mind the papers of Bruno Latour and Madaleine Akrich presenting what they call a "semiotics of human and nonhuman assemblies";[2] Donna Haraway's papers on what she calls "material-semiotic actors," notably her "Promises of Monsters,"[3] "Situated Knowledges," [4] and "Cyborg Manifesto";[5] and N. Katherine Hayles's proposal for enrolling these hybrids in a semiotically inspired program of "constrained constructivism."[6] By tracing the versions of semiotics presented in these papers to their source, I seek an answer to this question: was that last turn the right turn? ... more »

The setting wasn't Cambridge. Nor was it Harvard University, the California Institute of Technology or even Princeton, where Albert Einstein once taught. -- It was, instead, a pristine 6,000-acre stand of piney woods northwest of Houston where some of the world's most brilliant scientists — theoretical physicists who ponder the universe's deepest questions — chose to gather. Among them was perhaps the most famous living scientist, Stephen Hawking.
They had come at the behest of George Mitchell, a one-time wildcatter and the developer of The Woodlands, who in the last decade has gained a deep appreciation for cosmology, the science of the universe. -- With his largesse, more than $60 million and counting, Mitchell has begun centering Texas on the map in this most fundamental of scientific fields. more » Thursday, April 19

She's pretty enough to be mistaken for a Hollywood actress... But Seanne Corn's claim to fame is yoga. And for this reason, Hollywood celebs, businessmen, sports personalities, all seek her out.
"Yoga is evolving and growing in the West. So, I wouldn't call it a fad – no fad can last this long. Now, it is attracting younger, aggressive people who want more from their life. The interesting thing is, once they make yoga a part of their lives, they cease to want those things," says Seanne. But what is her connect with this ancient Indian practice? Seanne gets candid, "I was a very troubled teenager, doing drugs and alcohol. A friend told me in jest that yoga might make me more stable and level headed, and I took it seriously. I travelled to Mysore, and enrolled in the Aurobindo Ashram. I'm 40 now, and this happened when I was 19. So, for the past 21 years, yoga has been a way of my life," she says. ... more » Wednesday, April 18

If Albert Einstein were alive, he would have a copy of 'The Road to Reality' on his bookshelf. So would Isaac Newton. This may be the most complete mathematical explanation of the universe yet published, and Roger Penrose richly deserves the accolades he will receive for it. That said, let us be perfectly clear: this is not an easy book to read. The number of people in the world who can understand everything in it could probably take a taxi together to Penrose's next lecture. Still, math-friendly readers looking for a substantial and possibly even thrillingly difficult intellectual experience should pick up a copy (carefully--it's over a thousand pages long and weighs nearly 4 pounds) and start at the beginning, where Penrose sets out his purpose: to describe "the search for the underlying principles that govern the behavior of our universe."
Beginning with the deceptively simple geometry of Pythagoras and the Greeks, Penrose guides readers through the fundamentals--the incontrovertible bricks that hold up the fanciful mathematical structures of later chapters. From such theoretical delights as complex-number calculus, Riemann surfaces, and Clifford bundles, the tour takes us quickly on to the nature of spacetime. The bulk of the book is then devoted to quantum physics, cosmological theories (including Penrose's favored ideas about string theory and universal inflation), and what we know about how the universe is held together. For physicists, mathematicians, and advanced students, 'The Road to Reality' is an essential field guide to the universe. For enthusiastic amateurs, the book is a project to tackle a bit at a time, one with unimaginable intellectual rewards. ... more » Tuesday, April 17

...Esoteric Physics is the discipline that studies the laws of the universe and all the process through which practical magic works. The main applications and studies of esoteric physics regard cosmology, space and time, the structure of the form, human perceptions and sensitivity and, in a certain way, natural medicines. Esoteric physics explores all the correspondences of the universe with the human microcosms and its subtle and spiritual aspects: it’s a real pathway to knowledge and awareness, beyond this universe, towards the Infinite outside and inside of us...
Spirituality is not a theoretic and transcendent concept. It is rather action, experience, behaviour and responsibility. But it is also enchantment, mystic enthusiasm and rapturous contemplation of everything. As we are incarnated into the forms, Spirituality is made of actions, events, choices, imperfect things, not of sublime ideas: there is no space for superstition in a real pathway of research and there is no space for fanaticism since the greatest spiritual realisation is not to reach certainties, but, perhaps, the continuous availability to change, to pose questions, to grow and renew ourselves. ... more » Monday, April 16

Sweltering flight deck crews couldn’t launch Navy jets for extended periods of time. U.S. ground troops would find themselves splitting time between humanitarian relief operations and fighting insurgents bent on winning over desperate third-world peoples. Low-lying logistics hub Diego Garcia would be swallowed up by the Indian Ocean.
Global warming isn’t often thought of as a matter of interest for the U.S. military. But it should be, an advisory board of 11 retired flag officers concluded in a report issued Monday under the auspices of the Center for Naval Analyses, a non-profit national security analysis group. Climate change is happening, the blue-ribbon panel concluded, and is a “serious national security threat.” ... more » Sunday, April 15

The Indian Council of Philosophical Research (ICPR) is a unique institution, possibly one of its kind in the world... It started functioning [in]1981, thanks to the foresight and initiative of Smt. Indira Gandhi... The main argument in favor of the ICPR is that among various pursuits and disciplines of knowledge that came to be developed during the course of the long history of India, philosophy stands out as the single most outstanding endeavor. The classical Indian contributions in philosophy rival the very best any where in the world. If there is one single area of Indian excellence which would command respect and attraction from the contemporary world, it would be none other than the profound wisdom that is contained in Indian thought. So, it was felt that philosophy deserved to have a special agency in the country to help move it forward to new heights of excellence... Conceived as a crucible for molding thoughtful minds generating ideas needed for India’s development consistent with its national ethos, funded generously by the Government of India and led effectively by a series of outstanding scholars, today, the ICPR stands out as a beacon of light illuminating the intellectual landscape of the nation...
Dr. Kireet Joshi was the Chairman of ICPR from 2000-06. He was also its Member - Secretary for (1981-1990) 10 years. He was Chairman of Auroville Foundation and vice-Chairman of Maharshi Sandipani Rashtria Veda Vidya Pratisthan. He was formerly Educational Adviser to the Government of India and Special Secretary in the Ministry of HRD during 1976 to 1988. He has authored and edited a number of books in the areas of Value-Oriented Education, Indian Culture, Yoga, Sri Aurobindo and Mother. ... more » Saturday, April 14

This is one chicken I wouldn't like to meet in a dark alley!
________________________ Scientists have managed to extract proteins of collagen 1 from the bones of a 68-million-years-old Tyrannosaurus rex fossil. It was previously thought the protein in bones had a shelf life of around a million years. By comparison, DNA "survives" less than 100,000 years. The collagen protein was discovered in a thighbone unearthed four years ago under 20 yards of rock on a cliff in the Hell Creek Formation, which spans the Wyoming, Montana and the Dakotas in the northwestern U.S. Reporting in two papers in the new issue of Science, the team of researchers announced that a chemical analysis of the T. rex peptides suggests the king of the lizards is most similar to a present-day chicken. ... more » Friday, April 13

Thanks to Yatanti for referring us to this site re "The Works of Rabindranath Tagore" and other sacred texts. ~ ron
_________________ Rabindranath Tagore (1861-1941) was a Bengali poet, philosopher, artist, playwright, composer and novelist. India's first Nobel laureate, Tagore won the 1913 Nobel Prize for Literature. He composed the text of both India's and Bangladesh's respective national anthems. Tagore travelled widely and was friends with many notable 20th century figures such as William Butler Yeats, H.G. Wells, Ezra Pound, and Albert Einstein. While he supported Indian Independence, he often had tactical disagreements with Gandhi (at one point talking him out of a fast to the death). His body of literature is deeply sympathetic for the poor and upholds universal humanistic values. His poetry drew from traditional Vaisnava folk lyrics and was often deeply mystical. more »
LAST night I dreamt that I was the same boy that I had been before my mother died. She sat in a room in a garden house on the bank of the Ganges. I carelessly passed by without paying attention to her, when all of a sudden it flashed through my mind with an unutterable longing that my mother was there. At once I stopped and went back to her and bowing low touched her feet with my head. She held my hand, looked into my face, and said: "You have come!" In this great world we carelessly pass by the room where Mother sits. Her storeroom is open when we want our food, our bed is ready when we must sleep. Only that touch and that voice are wanting. We are moving about, but never coming close to the personal presence, to be held by the hand and greeted: "You have come!" ... Thursday, April 12

...If we define the topic as the relation between the reader's, the character's, and the author's willingness to believe, then the matter is very different in Valis. In Valis the text does not offer the reader the incredible as already labeled incredible — zany or horrifying, extreme or bizarre. The incredible is offered as ordinary, as reportage. Is not this the frisson worked by this novel? Anyone reading a novel such as Ubik has to accept that the novel offers something visionary and phantasmagoric. Whether one then emphasizes the novel's treatment of the deliquescence of commodity in late capitalism, or, with George Slusser, one then emphasizes its rendition of ``historicity'' in relation to an open, Emersonian event horizon, one has to pay attention to that explicit inventiveness which constitutes the shimmering portal... through which any reader gains entrance to that novel and others like it. Valis is different. ...
Many of Dick's values are strongly liberal and humanist. He values the little guy who dissents, resists, and persists, if necessary, alone; he values the single humble act, the individual saved..., the broken pot fixed, the embrace of two strangers in the dark and rain-spattered forecourt of a gas station... And liberal values, and hopes, are subjected to intense torsion, or distortion, in Dick's novels. [Fredrick] Jameson has traced this in Dr. Bloodmoney, whose bizarre cast's weird actions he sees as Dick's response to a threatened "leftist" belief that good and evil in history can be attached to individuals. Dick values that which is unassimilated — unassimilated into the mechanical and collective, into an oppressive society, into a single godhead, into entropy; but the urgency of assertion and defense of that value leads him to break all traditional definitions of the human individual. Liberal humanism, passed through this sieve, emerges as intuition of the potential value in androids, gods, animals, robots: anywhere and wherever life asserts a distinctness, rather than threatening it. The issue must be fraught with danger: vindication of the human, if it is to be achieved, will only be effective if the human has been profoundly jeopardized. ... more » |
