قال الله تعالى

 {  إِنَّ اللَّــهَ لا يُغَيِّــرُ مَـا بِقَــوْمٍ حَتَّــى يُـغَيِّـــرُوا مَــا بِــأَنْــفُسِــــهِـمْ  }

سورة  الرعد  .  الآيـة   :   11

ahlaa

" ليست المشكلة أن نعلم المسلم عقيدة هو يملكها، و إنما المهم أن نرد إلي هذه العقيدة فاعليتها و قوتها الإيجابية و تأثيرها الإجتماعي و في كلمة واحدة : إن مشكلتنا ليست في أن نبرهن للمسلم علي وجود الله بقدر ما هي في أن نشعره بوجوده و نملأ به نفسه، بإعتباره مصدرا للطاقة. "
-  المفكر الجزائري المسلم الراحل الأستاذ مالك بن نبي رحمه الله  -

From the window of a Nasa aircraft flying over the Arctic, looking down on the ice sheet that covers  most of Greenland, it’s easy to see why it is so hard to describe climate change. The scale of polar ice, so dramatic and so clear from a plane flying at 450 metres (1,500ft) – high enough to appreciate the scope of the ice and low enough to sense its mass – is nearly impossible to fathom when you aren’t sitting at that particular vantage point. But it’s different when you are there, cruising over the ice for hours, with Nasa’s monitors…
Background Little information is available about the geo-economic variations in demographics, management, and outcomes of patients with acute respiratory distress syndrome (ARDS). We aimed to characterise the effect of these geo-economic variations in patients enrolled in the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG SAFE). Methods LUNG SAFE was done during 4 consecutive weeks in winter, 2014, in a convenience sample of 459 intensive-care units in 50 countries across six continents. Inclusion criteria were admission to a participating intensive-care unit (including transfers) within the enrolment window and receipt of invasive or non-invasive ventilation.…

10 INCREDIBLE HEALTH BENEFITS OF FASTING

كتبه
Many people observe fasting as a religious obligation but only few know the health benefits it has. Fasting is a good practice, if properly implemented. It promotes elimination of toxins from the body, reduces blood sugar ans fat stores. It promote healthy eating habits and boost immunity. Here are top 10 health benefits you ca derive from fasting. 1. Fasting Promotes detoxification Processed foods contain lots of additives. These additives may become toxins in the body. Some of them promote production of advanced glycation end products (AGEs). Most of these toxins are stored in fats. Fat is burnt during fasting,…
NTRODUCTION Scientists and inventors can combine information from an ever-expanding knowledge base dispersed across documents, experiments, and data (1). The Web of Science (WOS) contains 28.4 million publications, including more than 1.5 million new articles published in 2014 alone, sextupling the 1970 rate. The U.S. Patent and Trademark Office (USPTO) issued 287,831 patents in 2013, quadrupling the 1970 rate. Although more knowledge enables more novel ideas to be combined (2, 3), scientists and inventors have limited time to search through the expanding base (4, 5). As the rate of knowledge expansion grows, but the time to search for new knowledge remains fixed,…

US child-health study rises from ashes of high-profile failure

كتبه
Frederica Perera has stocked a dozen freezers with an unusual biological bounty over the past two decades. Inside are vials of umbilical-cord blood, urine and placentas from more than 700 pregnant women and their children from the Washington Heights, Harlem and South Bronx neighbourhoods of New York City. This biobank has proved invaluable in her efforts to understand how urban environments influence children’s health from birth through childhood. Now, Perera’s team is gearing up for another challenge: developing a tool that can test her bank of umbilical-cord blood samples for common pollutants and use the results to predict later impacts…

Geologists spy an eighth continent: Zealandia

كتبه
Beneath the waves in the southwest Pacific Ocean lies a mostly hidden realm — dubbed Zealandia — that deserves to be called a continent, geologists say. Geophysical data suggest that a region spanning 5 million square kilometres, which includes New Zealand and New Caledonia, is a single, intact piece of continental crust and is geologically separate from Australia, a team of scientists from New Zealand, Australia and New Caledonia argue in the March/April issue of GSA Todayhttp://dx.doi.org/10.1130/GSATG321A.1 (2017)." class="ref-link" style="color:rgb(92, 121, 150);text-decoration:none">1. (see 'Hidden crust') “If you could pull the plug on the world’s oceans, then Zealandia would probably long ago…

Carbon Cache

كتبه
Near a bank of windows overlooking the mighty Klamath River, Yurok tribal leader Susan Masten proudly displays photo after photo of intricate Yurok baskets and ceremonial caps, part of a cache of priceless cultural artifacts the California tribe has recently reclaimed. Assembled over decades by a non-Yurok art collector, the collection had a hefty price tag. But thanks to income from the innovative forest carbon offset program that The Nature Conservancy helped develop in California, the Yuroks were able to bring these treasures home in 2014.“It’s as if you could hear them saying, ‘Take me home, take me home,’” says…

With civilian drone competition, Iran battles against brain drain

كتبه
TEHRAN — The 26 drone-building teams descended on the polished, manicured technology park 15 miles east of Tehran with the overflowing enthusiasm of school kids preparing for the Science Olympiad. Their challenge, in a competition sponsored by the fast-growing Digikala company, Iran’s version of Amazon, was to create the best drone for delivering packages. For the drone builders, the prize that day at Pardis Technology Park, Iran’s purpose-built version of Silicon Valley, was 50 million tomans, or about $14,300. But for Iran, the goal was much greater: a step toward providing the country’s whiz-kid youth with the hope that they have a…
NASA’s Curiosity rover completed its second Martian year - 687 Earth days - on May 11, meaning that its instruments have now tasted the red planet’s tendencies for two full orbits of the sun. This allows scientists to begin separating unique events from those that recur year by year, laying the foundation for an understanding of seasonal variations in a host of different characteristics. The fresh insights come at a time when talk of a manned mission to Mars is edging away from the arena of science fiction and towards the realm of human endeavor. "Curiosity's weather station has made…
It's a strong contender for the geekiest video ever made: a close-up of a smartphone with line upon line of numbers and symbols scrolling down the screen. But when visitors stop by Nicola Marzari's office, which overlooks Lake Geneva, he can hardly wait to show it off. “It's from 2010,” he says, “and this is my cellphone calculating the electronic structure of silicon in real time!” Related stories The chips are down for Moore’s law The super materials that could trump graphene Materials science: The hole story More related stories Even back then, explains Marzari, a physicist at the Swiss…
