New Superconducting Material discovered in Transition-Metal Dichalcogenides Materials

Posted by in categories: chemistry, energy

With the support of electrical transport and magnetic measurement systems of Steady High Magnetic Field Facility (SHMFF), a research team from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), discovered a new superconducting material called (InSe2)xNbSe2, which possesses a unique lattice structure. The superconducting transition temperature of this material reaches 11.6 K, making it the transition metal sulfide superconductor with the highest transition temperature under ambient pressure.

The results were published in Journal of the American Chemical Society.

TMD materials have received lots of attention due to their numerous applications in the fields of catalysis, energy storage, and integrated circuits. However, the relatively low superconducting transition temperatures of TMD superconductors have limited their potential use.

A nanotechnology‐based CRISPR/Cas9 delivery system for genome editing in cancer treatment

Posted by in categories: biotech/medical, nanotechnology

In the presence of protospacer adjacent motif (PAM), sgRNA accurately leads the Cas9 endonuclease to the target regions, where it causes DNA double strand breaks (DSBs), resulting in site‐specific genomic change. Endogenous DNA repair can take place following the creation of a DSB via two primary genome editing pathways: nonhomologous end joining (NHEJ) or homology‐directed repair (HDR).

By using the biological characteristics of Cas9 targeting specific DNA sequences under the guidance of sgRNA, scientists have further developed gene targeting activation and gene targeting inhibition tools based on dCas9, called CRISPRa and CRISPRi respectively.

In the paper, characteristics of three forms of CRISPR/Cas9 cargos are outlined. Three delivery forms of the CRISPR/Cas9 system are plasmids, mRNA/sgRNA, and ribonucleoprotein (RNP) complexes, each of which has its own advantages and disadvantages.

China plans big tech move to rival Elon Musk’s Neuralink by 2025

Posted by in categories: computing, Elon Musk, neuroscience, policy

The recently published tech policy document by the Ministry of Industry and Information Technology reflects their dedication to fostering innovation and development in future industries. The roadmap emphasizes the importance of forward-looking planning, policy guidance, and cultivating new quality productive forces to support the country’s aspirations for global technological leadership.

The race for supremacy in brain-computer interfaces intensifies as the world watches China’s technological journey unfold. With Neuralink marking its milestones, China’s bold ambitions signal a new era of competition in the ever-evolving landscape of cutting-edge technologies.

The question now is not just about who will lead the race but what groundbreaking innovations lie ahead for humanity.

DNA Targeting Drug Shows Efficacy for Colorectal Cancer

Posted by in categories: biotech/medical, genetics

Colorectal cancer (also called bowel cancer) typically develops in the large bowel (colon) or rectum. Recent studies have shown significant rises in the number of colorectal cancer cases, particularly those in young adults. As we discussed earlier, the recently released estimated cancer statistics for 2024 predict colorectal cancer as the leading cause of mortality in men under 50 and the second-leading cause of mortality in women. Additionally, experts predict over 150,000 new cases of colorectal cancers this year.

To combat these troubling figures, ongoing research focused on the prevention and treatment of colorectal cancers remains a high priority and urgent need. This includes data recently published in Science Advances which demonstrates pre-clinical efficacy for a new treatment approach.

The study involves genetic material known as microbial or mislocalized DNA. This type of DNA arrises from cells that become damaged, thus no longer providing the correct genetic instructions. Damaged DNA can elicit various reactions in the body, including activating the immune response. Damaged DNA can therefore influence how the body responds to diseases, including colorectal cancer.

New tandem solar panel achieves world record conversion efficiency, 25%

Posted by in categories: solar power, sustainability

A pivotal achievement has been reached in the realm of energy transition with the development of a cutting-edge tandem solar panel. Interestingly, the solar panel has demonstrated an impressive conversion efficiency rate of 25 percent.

The 25 percent efficiency is a significant improvement above the average 24 percent efficiency found in commercial modules. This makes it the world’s most efficient perovskite silicon tandem solar module in an industrial configuration, as per the release.

This remarkable achievement marks a crucial milestone in the global transition towards sustainable energy sources.

Breakthrough could see robots with ‘fingertips’ as sensitive as humans

Posted by in categories: biotech/medical, cyborgs, food, robotics/AI

Researchers have overcome a major challenge in biomimetic robotics by developing a sensor that, assisted by AI, can slide over braille text, accurately reading it at twice human speed. The tech could be incorporated into robot hands and prosthetics, providing fingertip sensitivity comparable to humans.

Human fingertips are incredibly sensitive. They can communicate details of an object as small as about half the width of a human hair, discern subtle differences in surface textures, and apply the right amount of force to grip an egg or a 20-lb (9 kg) bag of dog food without slipping.
