3D-printed tissues using stem cells may offer repair for brain injuries

6.10.2023   |   Press monitoring

Researchers have used human neural stem cells to 3D print functional brain tissue that mimics the architecture of the cerebral cortex, the brain’s outermost layer. The breakthrough technique has the potential to provide individualized repairs to brain injuries. Our brains have a delicate and complex architecture that can be damaged by trauma,...

Graphene oxide nanoflakes reduce the toxicity of Alzheimer\'s proteins, shows study

4.10.2023   |   Press monitoring

A probable early driver of Alzheimer's disease is the accumulation of molecules called amyloid peptides. These cause cell death and are commonly found in the brains of Alzheimer's patients. Researchers at Chalmers University of Technology, Sweden, have now shown that yeast cells that accumulate these misfolded amyloid peptides can recover after...

Transposable elements study reveals potential methods to stop aging

2.10.2023   |   Press monitoring

Researchers Dr. Ádám Sturm and Dr. Tibor Vellai from Eötvös Loránd University, Hungary have made an exciting breakthrough in understanding how we age. They focused on "transposable elements" (TEs), which are parts of DNA that can move around in our genetic code. When these TEs move too much, they destabilize the genetic code and that can be the...

Scientists discover biomimetic macrophage technology to combat antibiotic resistance

29.9.2023   |   Press monitoring

A research team led by Shuilin Wu at Tianjin University, China, has made a discovery in the field of intelligent catalysis. Infections caused by multidrug-resistant (MDR) Gram-negative bacteria, such as MDR Escherichia coli (E. coli), pose a significant challenge to health care professionals worldwide. The lack of safe antibiotics and the high...

Researchers develop minimal nanozymes with carbon dioxide capture capacity

27.9.2023   |   Press monitoring

Autonomous University of Barcelona (UAB) researchers have developed minimal nanozymes with the capacity of capturing carbon dioxide (CO2) emitted in industrial processes – and applicable to other environmental remediation processes – based on artificial molecular structures formed by the peptides of only seven amino acids. These new molecules...

Genetically modifying individual cells in animals

25.9.2023   |   Press monitoring

One proven method for tracking down the genetic causes of diseases is to knock out a single gene in animals and study the consequences this has for the organism. The problem is that for many diseases, the pathology is determined by multiple genes. This makes it extremely difficult for scientists to determine the extent to which any one of the...

Nanoparticles made from plant viruses could be farmers new ally in pest control

22.9.2023   |   Press monitoring

A new form of agricultural pest control could one day take root – one that treats crop infestations deep under the ground in a targeted manner with less pesticide. Engineers at the University of California San Diego have developed nanoparticles, fashioned from plant viruses, that can deliver pesticide molecules to soil depths that were previously...

Bionic silkworms with spider genes spin fibers 6x tougher than Kevlar

20.9.2023   |   Press monitoring

For the first time, scientists have successfully produced full-length spider silk fibers using genetically modified silkworms. With high strength and toughness, this silk has the potential to provide a scalable, sustainable and better-quality alternative to current synthetic fibers like nylon. The fibers that silkworms build their cocoons with...

Dual Trojan Horse strategy to combat superbugs

18.9.2023   |   Press monitoring

In the relentless battle against antibiotic-resistant superbugs, science continues to unveil ingenious strategies to address their vulnerability. Like other bacteria, superbugs have a unique weakness – their dependence on iron for growth and survival. Iron serves as an essential nutrient that bacteria utilize for various cellular processes,...

Phosphorus-based nanotech rips apart superbugs & accelerates healing

15.9.2023   |   Press monitoring

Researchers have found that using nano-sized flakes of black phosphorus on wounds infected with drug-resistant superbugs not only kills the pathogens, but also promotes wound healing. More than a coating, the innovative antimicrobial can be incorporated into common materials such as dressings, gels, and plastics. Black phosphorus has recently...
