Stem cell therapy successful repairs spinal cord injury

Posted by in category: biotech/medical

The results of the study have been extremely encouraging, with 12 of the 13 patients showing signs of improved neurological functionality shortly after the treatment was administered. More than half of the patients showed significant improvement, including regaining the ability to walk, as well as regaining fine motor control (such as the ability to use their hands).

Unlike many stem cell treatments which have been successful in the past, this approach does not require the patient to have a reserve of stem cells available (such as cord blood cells), and instead relies on stem cells which are obtained directly from the patient. A bone marrow sample was extracted in order to first acquire a sample of stem cells (known as mesenchymal stem cells), which were then grown (expanded) in a laboratory for the number of weeks before being injected into the patient’s bloodstream via intravenous injection. These cells would then migrate to the spinal cord and repair the damaged tissue.

Amazon Web Services says will open data centers in Israel

Posted by in categories: computing, military

Amazon Web Services (AMZN.O) said it will open data centers in Israel, with the announcement coming weeks after Israel signed a deal with AWS and Google for a more than $1 billion project to provide cloud services for its public sector and military.

In April, AWS and Google (GOOGL.O) won a tender for the four phase project known as “Nimbus”. read more

“Today, Amazon Web Services Inc, an Amazon.com company, announced it will open an infrastructure region in Israel in the first half of 2023”, AWS said in a statement on Friday.

These Tiny Creatures Were Revived After 24,000 Years Frozen in The Siberian Permafrost

Posted by in categories: biological, chemistry

For tens of thousands of years, a microscopic creature lay frozen and immobile underground in the Siberian permafrost.

Yet, when scientists thawed it out, the tiny multicellular animal didn’t just revive — it reproduced, suggesting that there is a mechanism whereby multicellular animals can avoid cell damage during the freezing process and wake up ready to rumble.

“Our report is the hardest proof as of today that multicellular animals could withstand tens of thousands of years in cryptobiosis, the state of almost completely arrested metabolism,” said biologist Stas Malavin of the Soil Cryology Laboratory at the Institute of Physicochemical and Biological Problems in Soil Science in Russia.

Say goodbye to your camera bump: Miniaturized optics through new counterpart to lens

Posted by in categories: mobile phones, quantum physics, space

ANOTHER OPTICAL BREAKTHROUGH COMPLEMENTING METALENSES. In addition to the ongoing revolution in optical science brought about by flat metalenses and single-photon image sensors, there is another parallel and complementing new dimension now added to the mix, which, according to this article, will allow telescopes as thin as a piece of paper.


Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone?

In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives.

New connector for sustainable structures on Earth and in space

Posted by in categories: engineering, space, sustainability

As part of his Master’s degree in civil engineering, an EPFL (Ecole Polytechnique Federale de Lausanne) student developed a connector for use in building sustainable structures. His initial project has expanded into an online program for designing bamboo furniture that’s stylish, modular and customizable. And now his connector is being looked at for use by astronauts in outer space.

During his time at EPFL under the Erasmus program, Romain van Wassenhove came up with an idea for a connector that could be used to make modular structures out of sustainable rather than wood, plastic or metal. “I wanted to focus my Master’s on a topic that had meaning to me and that would lead to a concrete application,” he says. “Working with bamboo was something I already had in mind while I was studying in Brussels.” His connectors can be 3D-printed in biosourced plastic and are customizable to the type of material used for the structure.

Van Wassenhove got the idea for his connector during a class at EPFL on composite materials and developed the concept further through his Master’s project, co-directed at EPFL by Senior Scientist Anastasios Vassilopoulos and by associate professor Lars De Laet at Vrije Universiteit Brussel (VUB). In September 2020, soon after graduating, he obtained research funds—through an EPFL Ignition Grant—to enhance the design and operation of his connector and test it on an initial application involving bamboo structures. Today van Wassenhove’s invention is EU patent-protected, and his research has just been published in Composite Structures.

Across China, AI city brains are changing how the government runs

Posted by in categories: biotech/medical, government, robotics/AI, surveillance

It is called the “city brain”, an artificial intelligence system that is now being used across China – only megacities could afford them before – for everything from pandemic contact tracing to monitoring illegal public assemblies and river pollution.


Authorities at all levels are now using AI for everything from pandemic control to monitoring illegal public assemblies.
