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  -

China is expanding its control over the use of genetic data from people in the country, including for scientific research. Researchers say this approach is making it harder for scientists there to collaborate with international peers. A set of draft guidelines, released by China’s Ministry of Science and Technology (MOST) in March, are the latest in a series of government orders on managing genetic resources — including biological samples, such as organs, tissues and blood, that yield DNA, and the data gleaned from sequencing them. The guidelines provide detailed instructions on how to interpret and implement existing regulations. This includes…

Meta is using AI to create low-carbon concrete for its data centres

كتبه
Facebook’s parent company, Meta, has used AI to develop a new way of creating concrete which it claims produces 40 per cent less carbon emissions than standard mixtures, and is already using it in its latest data centre. But experts say that concrete mixtures with similar emissions are already in use across Europe, and that constructing new buildings is incompatible with reducing carbon pollution. Meta is investing heavily in AI research, including building the world’s most powerful AI-specific supercomputer. Its main aims are to develop better speech-recognition tools, automatically translate between different languages and help build a 3D virtual metaverse, but…

Jian-Wei Pan leads China’s quantum computing successes

كتبه
GOVERNMENTS and companies around the world are racing to build a useful quantum computer, and the stakes are as high as the R&D budgets. Such a machine could crack encryption wide open, boost the power of artificial intelligence and help develop unique materials and drugs. A big player in the field is China, which has a centralised and extremely well-funded government project hoovering up talent, all under the oversight of one man: Jian-Wei Pan. The same words crop up repeatedly when you discuss Pan with those who know him: reserved, focused, driven and bright. He is often referred to as…

Deep-sea rockfish that live to be 200 hint at genes for longevity

كتبه
Longevity research often focuses on short-lived lab animals like mice – but a study of long-lived rockfish might offer new genetic clues for extending lifespans Rockfish are among the longest-living animals known to exist, and by studying the natural variation in their lifespans, researchers have discovered key insights into the genetic basis of longevity. Studies into ageing have traditionally focused on laboratory mice because they are easy to work with. However, Peter Sudmant at the University of California, Berkeley, and his colleagues adopted a different approach, studying longevity in creatures with longer lifespans. The researchers performed a genomic analysis of 88 species…

What Went Wrong With Russia’s Sputnik V Vaccine Rollout?

كتبه
In August 2020, Russia was the first country to announce the development of a COVID-19 vaccine. Since then, a relentless publicity blitz has promoted the attributes of the Sputnik V vaccine. However, Sputnik V has struggled to gain mass acceptance inside Russia, let alone in other countries where it is marketed as an alternative to vaccines developed by Western and Chinese pharmaceutical firms. Hovering over the vaccine’s commercial prospects are lingering questions about its safety and efficacy—as well as Moscow’s ability to deliver promised numbers of doses and navigate complicated global supply chains. HOW HAS SPUTNIK V’S ROLLOUT GONE? The developers of Sputnik V at Moscow’s…

Mystery microbes have been lurking unsuspected in most coral species

كتبه
It has long been known that coral polyps harbour algal symbionts that make most of their food. Now it has been shown that corals can also harbour microbes that appear to be parasites but don’t seem to harm their hosts. “The fact that we could go out to a coral reef, which is probably the best studied marine environment, and specifically look at the coral, which is the best studied part of that environment, and find a parasite that infects virtually every species of coral we’ve looked at, that no one had ever really noticed, blows my mind,” says Patrick Keeling at the University…

How fast does Earth spin?

كتبه
To answer the question of how fast Earth spins, you need to know two things: how long it takes to make a full rotation, and Earth’s circumference. The time it takes Earth to rotate so the sun appears in the same position in the sky, known as a solar day, is 24 hours. However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal day. With this information, to work out how fast Earth is spinning we need only our…

Fish are becoming addicted to methamphetamines seeping into rivers

كتبه
Illicit drug use is a growing global health concern that causes a financial burden of hundreds of billions of dollars in the US alone. But hidden beneath the societal costs of this human epidemic is a potential ecological crisis. As methamphetamine levels rise in freshwater streams, fish are increasingly becoming addicted. “Where methamphetamine users are, there is also methamphetamine pollution,” says Pavel Horký at the Czech University of Life Sciences. Humans excrete methamphetamines into wastewater, but treatment plants aren’t designed to deal with such substances. Because of this, as treated wastewater flows into streams, so do methamphetamines and other drugs. In some streams…

What I Know and Don’t Know about SARS-CoV-2 Virus

كتبه
After fifteen months of assiduous reading, study, observation, and research, I have come to some conclusions about what is called COVID-19.  I would like to emphasize that I have done this work obsessively since it seemed so important.  I have consulted information and arguments across all media, corporate and alternative, academic, medical, books, etc.  I have consulted with researchers around the world. I have read the websites of the CDC, the World Health Organization, and government and non-government health organizations.  In other words, I have left no stone unturned, despite the overt or covert political leanings of the sources.  I have…
Due to unanswered questions into the origins of the coronavirus pandemic, both the U.S. government and scientists have called for a deeper examination into the validity of claims that a virus could have escaped from a lab in Wuhan, China. Much of the discussion surrounds “gain-of-function” research. So The Conversation asked David Gillum and Rebecca Moritz, who work closely with virologists on a day-to-day basis to ensure the safety and security of the research, and Sam Weiss Evans and Megan Palmer, who are science and technology policy experts, to explain what this term means and why this kind of research is important. What does gain of function mean? Any organism…
SpaceX put 60 Starlink satellites in space May 23, the first little chunk of an eventual 12,000-satellite-strong "megaconstellation" that the private company plans to place in orbit. Not long after the launch, observers and astronomers noticed something: This train of five dozen objects looked really bright overhead — unusually bright for artificial satellites. And this light show has many astronomers worried. "The Starlink satellites just passed directly overhead," Boulder, Colorado-based astronomer Alex Parker tweeted Saturday (May 25). "They were glinting, some as bright as Polaris. Quite an eerie looking thing. And yes, the stars are out." Parker, an expert in orbital mechanics, caused a stir…
