    Rhode Island state Sen. Rhoda Perry, D-Providence, smiles as she is greeted by a colleague in the Senate Chamber at the Statehouse, in Providence, Tuesday, June 7, 2005, seconds after the Senate passed a bill that would shield medical marijuana users from prosecution. The vote comes a day after the U.S. Supreme Court ruled that people who use marijuana for medical purposes could still be prosecuted under federal law.

    Bose-Einstein Condensates Interfere and Survive

    A Bose-Einstein condensate in a dilute gas is a collective state of atoms that acts like a quantum mechanical wave with a phase. In his Perspective, Javanainen highlights the demonstration by Saba et al. that the phase difference between two condensates can be measured without destroying the condensates. The experiments open up new ways to manipulate condensates, which are macroscopic objects, as if they were quantum mechanical entities. Measurement devices based on matter-wave interferometry are a potential application.

    کره زمین

    حقیقت است، کره زمین عاقبت در آتشی مهیب خواهد سوخت اما نه به دلیلی های که شنیده اید.

    کره زمین، کره نسبتاً جوانی است که نقشش فراهم کردن یک محیط آموزشی برای روح است. مانند انسان، زندگی های زیادی دارد. بعد از هر زندگی به یک خوابی طولانی می رود. در طول آن خواب خود را نو سازی کرده و با معدن های پر و خاکی دوباره حاصلخیز، در استقبال دانش آموزان جدیدش به انتظار می ماند. روح های تازه از راه رسیده را از عصر حجر تا عصر فضا و کوچ، نگهداری می کند. حوادثی مانند؛ بالا رفتن بیش از حد جمعیت در آن واحد، آلوده شدن خاک و معدن های آب از طریق مواد شیمیائی، اتمی و فاضل آب ها، می توانند توازن زمین را به هم زده و اشکال ایجاد کنند. انسان اولین ساکن کره زمین نیست. گروه های دیگری قبل از او در این کره زندگی را از غار نشینی آغاز کرده، به عصر صنعتی و بعداً فضا رسیده و زمین را عاقبت بخاطر کره های بهتر و جوانتری برای همیشه ترک کرده اند.

    در حال حاضر، کره زمین با چندین خطر بزرگ روبرو است. بزرگترینش، افزایش بیش از حد جمعیت است که تمام خطرهای دیگر همه از آن منشاء می گیرند. این افزایش بی معیار باعث قحطی، جنگ، سوء استفاده از منابع طبیعی و آلودگی سریعتر کره زمین شده است.

    یک سالن غذا خوری را در نظر بگیرید، فرض کنید که این سالن گنجایش و توانائی آماده کردن غذا برای هزار نفر را در روز دارد، هفت روز در هفته. حالا مجسم کنید که ناگهان دو هزار نفر در روز تصمیم می گیرند برای غذا خوردن وارد این سالن بشوند. سر جا، نوبت، غذا، جنگ جدال ها براه خواهد افتاد. شلوغی و آشوب باعث از هم پاشیده شدن و کثیف شدن بیش از حد سالن خواهد شد. ذخیره آشپزخانه بسرعت از بین خواهد رفت.

    ازدیاد نامیزان و ناگهانی جمعیت زمین باعث شده است که نیاز برای محصولات کشاورزی، صنعتی و غیره به سرعت بالا برود. شتاب برای افزایش تولید این محصولات از یک سو، طمع مالی، قدرت و اعتبار سیاسی جوئیدن، از سوی دیگر باعث شده است که بسیاری از کشورها روز بروز استفاده از مواد شیمیایی و اتمی را گسترش بدهند. نتیجه، آلوده و سمی شدن منابع آب و خاک. افزایش جمعیت باعث شده است که فاضل آب های وسیع و تصویه نشده فراوانی در گوشه های مختلف دنیا، آب و خاک را آلوده کرده، سلامتی و هستی مردم آن منطقه هارا تهدید کنند. کارخانه های برق اتمی و بمب های اتمی، خطرهایی دیگری هستند که زمین با آن روبرو است. برای از بین بردن زمین، لازم نیست که انسان از بمب های اتمی استفاده کند. انفجارهای امتحانی آنها (حتی در منطقه های خالی ومتروک) به اندازه کافی گرد و غبار مسموم کننده در فضا رها می کند که خاک و آب آن منطقه را تا صدها کیلومتری برای قرن ها آلوده و مسموم خواهد کرد. تا چندین نسل، سرطان، نقص تولد، نازایی و.. هدیه آن منطقه به ساکنانش خواهد بود. اگر به کارخانه های برق اتمی دور دنیا نگاه کنید می بینید که بدون استثناع، در صد سرطان و نقص تولدی مردمی که در آن کارخانه ها کار می کنند و یا در حومه چند صد کیلو متری آن ها زندگی می کنند، مخصوصا کودکان، بسیار بیشتر از منطقه های دیگر است. البته هیچ دولتی این حقیقت را اقرار نخواهد کرد. میله های سوخته شده اتمی (تفاله کارخانه های برق اتمی) تا هزاران سال آلوده و سرطان زا مانده و از بین نمی روند. هیچ کاری هم با آن ها نمی شود کرد. حتی کشورهایی که تکنولوژی برتری دارند، زیر بار این مشکل مانده اند که با این آشغال های اتمی چه کنند. به تصادف اتمی کارخانه برق "چرنوبل" روسیه نگاه کنید، تا هزاران کیلو متری، جز سرطان، حیوان های پنج پا، کودکان سه دست و مزرعه های سمی و مرده چیز دیگری نمی توان یافت.

    ازدیاد جمعیت، طمع، منفعت و اعتبار طلبی کمپانی ها و کشورها، روی هم رفته باعث آهسته کشتن زمین شده اند.

    اگر همان پول و انرژیی را که انسان صرف پژوهش و ساخت نیروی اتمی و بعداً تمیز کردن آلودگی های آن می کند، صرف تحقیق و تولید نیرو از منابع دیگری مانند خورشید، باد و جزر و مد بکند، نه تنها محیط زیست خود را سالم نگه می دارد، بلکه می تواند نیروی برق بسیار بیشتری، با نرخی بسیار ارزانتر تولید نماید.

    باید به خاطر داشت که بسیاری از ذخیره های معدنی زمین محدود و پایان پذیرهستند. نفت خام بعنوان مثال. بسیاری از این مواد ها، فقط یک وسیله ای هستند که انسان بتواند آنرا برای رفتن از یک مرحله تحول یا انقلاب صنعتی اش به مرحله دیگری استفاده کند.

    همه دنیاها وقتیکه انرژی کره هایشان تمام می شود، پایان می یابند. نقشه سیر تکاملی زندگی در داخل یک سیستم ستاره ای همیشه طوری کشیده شده است که از طول زندگی آن کره، طولانی تر نباشد. یعنی اینکه تمام موجودات کره زمین، رشدشان را خیلی زودتر از پایان عمر این کره تکمیل کرده و پایان خواهند داد. در آن هنگام، کره زمین اول به یک توپ مهیب آتش تبدیل خواهد شد و بعداً خاموش شده و جز اثر کوچکی، چیز دیگری از آن باقی نخواهد ماند.

    Schiavo had irreversible brain damage-autopsy

    Terri Schiavo, a Florida woman who died in March after a fierce right-to-die battle that involved the U.S. Congress, was severely brain damaged and had no hope of recovery, said a medical examiner who gave the results of an autopsy on June 15 2005. 'Her brain was profoundly atrophied,' Pinellas County medical examiner Jon Thogmartin told a news conference, adding that her brain weighed about half what a healthy human brain weighs. 'This damage was irreversible.' File photo showing Terri Schiavo with her mother, Mary Schindler in a photograph taken late in 2001.

    But if they have a right to live shouldn't they have a right to die, I mean its kind of reciprocal. Her brain damage was irreversible and you of all ppl Musalmon, who believe in a heaven should think that by letting her die you are releasing her soul and reuniting her with God or whatever. Man migam vakhti ye kasi shoroh kardi be mordan, buyad bezari as in donya bereh ke dombareh ruhesh aroomesh doshtebasheh.

    Cambodian Ministry of Agriculture officials gently release a giant catfish into the Tonle Sap River in Phnom Penh, Cambodia, Wednesday, June 15, 2005. Conservationists in Cambodia on Wednesday released into the Mekong River four endangered giant catfish that had been raised in captivity and kept by a man for good luck for seven years.

    Mexico's Volcano of Fire, also known as the Colima volcano, is seen in a time exposure photograph during an explosion as lava and hot rocks flow down its sides and lightning flashes over its crater late June 1, 2005. The photograph was taken with a four-minute exposure.

    Annelida
    Annelids can be told by their segmented bodies. Polychaetes (meaning "many bristles") have, predictably, many bristles on the body, while earthworms and leeches have fewer bristles. There are about 9000 species of annelid known today.

    In this photo provided by the San Diego Zoo, a six-day-old male Baringo giraffe is nuzzled by his mother Wednesday, June 15, 2005, at the San Diego Zoo's Wild Animal Park in San Diego. The calf, 6 feet tall, is the 94th Baringo giraffe born at the Wild Animal Park and the second this year, according to the zoo. Baringo giraffes, about 18 feet tall as adults, are native to Uganda, but are only found in two national parks in that African country.

    Journey to the centre of Earth

    David Adam in Yokohama
    Saturday June 4, 2005
    The Guardian

    Japanese scientists are to explore the centre of the Earth. Using a giant drill ship launched next month, the researchers aim to be the first to punch a hole through the rocky crust that covers our planet and to reach the mantle below.
    The team wants to retrieve samples from the mantle, six miles down, to learn more about what triggers undersea earthquakes, such as the one off Sumatra that caused the Boxing Day tsunami. They hope to study the deep rocks and mud for records of past climate change and to see if the deepest regions of Earth could harbour life.

    Asahiko Taira, director general of the Centre for Deep Earth Exploration in Yokohama, near Tokyo, said: "One of the main purposes of doing this is finding deep bacteria within the ocean crust and upper mantle. We believe there has to be life there. It's the same mission as searching for life on Mars."

    Rocks in the upper mantle produce compounds essential for life when they react with seawater. "This is a system which we believe created early life. There may be a chance that we can catch the origin of life still taking place today," Prof Taira said.

    The 57,500-tonne drill ship Chikyu (Japanese for Earth) is being prepared in the southern port of Nagasaki. Two-thirds the length of the Titanic, it is fitted with technology borrowed from the oil industry that will allow it to bore through 7,000 metres of crust below the seabed while floating in 2,500 metres of water - requiring a drill pipe 25 times the height of the Empire State building.

    The deepest hole drilled through the seabed so far reached 2,111 metres.

    After final sea trials this year, the scientists will set sail for the deep Pacific where the Earth's crust is thinnest. Drilling is expected to begin next year.

    It could take more than a year to drive through miles of crust and reach the mantle, so the ship is fitted with six rotating thrusters controlled by GPS satellites to keep it directly over the hole. The drill is surrounded by a sleeve that contains a shock-absorbing chemical mud, and a blowout valve will protect it should the team strike oil or superheated rock in the crust.

    The project is part of an international effort called the Integrated Ocean Drilling Programme which also involves the US and Europe.

    Shinichi Kuramoto, one of the Yokohama team, said Chikyu's main objective is to retrieve mantle samples for analysis. "Humans have brought back lunar rocks to understand the universe, yet we have never reached the mantle which accounts for most of earth."

    Previously undiscovered bacteria that can survive the anticipated 100C temperatures of the upper mantle could be useful on the surface. Heatproof enzymes isolated from bugs brought back by earlier Japanese drill missions are now used in washing powders.

    Cores of rock and sediment from the so-called "earthquake nest" where the mantle meets the crust could also help geologists understand seismic events, and to perhaps give more warning.

    "We can estimate how frequently marine sliding or earthquakes occur from learning the history of earth but we still don't know when they will occur in the future.

    "We take cores to better understand the mechanisms involved," Dr Kuramoto said.

    Sensors placed in the borehole could detect changes in strain, tilt and pressure in the ground miles below the surface. "That will be a great advantage in giving us a few days or hours warning before something happens. Current warning systems in Japan only warn us 10 minutes before a large earthquake strikes. We need real-time data from the exact point."

    Parapsychology Club learns all about auras

    An aura can change in the blink of an eye. Imagine learning you have won the lottery. While running across the street to tell your friends, your big toe is run over by a golf cart tire. In a split-second, your aura turns from the yellow shade of happiness to the sulfur shade of pain. Janet Carr knew this scenario was possible. After all, she has witnessed the rapid change in auras through aura photography. A computer whiz who has been into metaphysics for 12 years, Carr recently shared information about auras with members of The Villages Parapsychology Club."There is a lot of good energy in here," Carr told the group last Thursday at Mulberry Grove Center. "I can feel it, but I can't see it."Carr, a Brooksville resident, explained that auras are energy vibrations which surround living things. The vibrations manifest themselves in the form of colors that represent qualities and sentiments.According to Carr, individuals may be trained to see auras with the naked eye. Carr is in the process of learning to read auras.

    "The paranormal world understands all about energy," she said. "If you could see it, you would understand it, too."With a special camera that senses and draws energy, however, auras can be viewed and interpreted. Photographs taken with these cameras depict energy being received on the left side of the body, energy currently influencing one's life at the center, and energy being put out to the world on the right.Though she didn't tote along her camera equipment for the lecture, Carr told the group that she would return this summer to photograph some auras.

    the head of Cairo's upper council of antiquities Zahi Hawas pointing to the mummy of the legendary Pharaoh Tutankhamun before running it under the computer tomography scanner in Luxor 05 January 2005. The council has announced that Egyptian scientists have produced the first digital image of the face of Tutankhamun after scanning his 3,000 year old mummy. The tomb of the pharaoh, who died under mysterious circumstances at about the age of 25, was unearthed by British archaeologists in 1922 in the Valley of the Kings. The scan showed that the cranium was still intact.
