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  -

How to prevent humanity’s surrender to AI

كتبه
What has baffled humanity today is shocking mechanics built in the AI machines and tools. Altogether they are gradually replacing the work and skills carried out by humans for generations. By 2030, almost 47 per cent of the jobs that face high risks of automation would be taken over by AI. The loss of  man-controlled jobs would add woes to the economic plight  The arrival of Artificial Intelligence (AI) has dramatically changed our lives. Globalisation criss-crossing the globe has pushed human civilisation to new frontiers of change. And one of the most remarkable dynamics heralded by the forces of such…

What US midterm elections mean for climate policy and public health

كتبه
On 8 November, US voters will decide whether Democrats maintain their slim majority in both houses of Congress. This, in turn, will determine whether the administration of President Joe Biden will be able to pursue its agenda for the next two years. The midterm election – which takes place halfway through each presidential term – is also set to change the balance of power in state governments, with races in every state legislature and 36 gubernatorial elections. Here is how the election results could affect three key scientific issues: climate change, reproductive healthcare and covid-19 policy. Climate change The Inflation…
The James Webb Space Telescope has made the first clear detection of carbon dioxide in the atmosphere of a distant world, and there is also an unexpected bump in the data NASA’s James Webb Space Telescope (JWST) has spotted carbon dioxide in the atmosphere of a planet 700 light years away called WASP-39b. This is the first time the compound has been found in any exoplanet, and the observations also revealed hints of a mystery within the distant world. WASP-39b is huge. It has a mass similar to Saturn’s, anda diameter 1.3 times that of Jupiter. It orbits relatively close to its…
How the virus behind covid-19 enters the brain was somewhat of a mystery, but new evidence hints it may build tiny tubes from nose cells to brain cells that it can shuttle through. We may finally know how covid-19 enters the brain: new research suggests the virus responsible stimulates the growth of tiny tubes between nose and brain cells that it can tunnel through. Covid-19 has been linked with a range of neurological symptoms including brain fog and confusion. Autopsy studies have also detected the coronavirus in people’s brains. But how it gets there has been somewhat of a mystery. Previous studies suggest the…

Guardians of the brain: how a special immune system protects our grey matter

كتبه
The nervous and immune systems are tightly intertwined. Deciphering their chatter might help address many brain disorders and diseases. University in St. Louis   The brain is the body’s sovereign, and receives protection in keeping with its high status. Its cells are long-lived and shelter inside a fearsome fortification called the blood–brain barrier. For a long time, scientists thought that the brain was completely cut off from the chaos of the rest of the body — especially its eager defence system, a mass of immune cells that battle infections and whose actions could threaten a ruler caught in the crossfire.…
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…
