Implants made of your blood could repair broken bone
9.12.2024 | Press monitoring
The body has a remarkable ability to heal itself when injured, but of course it has its limits. Now scientists at the University of Nottingham have developed a way to improve on the natural process, making implants created from a patient’s own blood to regenerate injuries, even repairing bone. Bodily tissues can heal small cuts or fractures...
Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry
6.12.2024 | Press monitoring
A tiny, four-fingered hand folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, University of Illinois Urbana-Champaign researchers report. Dubbed the NanoGripper, the nanorobotic hand also could be programmed to...

Engineered enzymes may help plants adapt to higher temperatures
4.12.2024 | Press monitoring
As global temperatures rise, it's imperative that plants can adapt to new and changing conditions. Michigan State University researchers from the Walker lab are looking at ways to give plants an assist. More specifically, their research aims to help plants adapt to changing temperatures by introducing engineered enzymes that will increase...
Newly designed nanocrystals can kill bacteria under visible light
2.12.2024 | Press monitoring
Newly developed halide perovskite nanocrystals (HPNCs) show potential as antimicrobial agents that are stable, effective and easy to produce. After almost three years, Rice University scientist Yifan Zhu and colleagues have developed a new HPNC that is effective at killing bacteria in a biofluid under visible light without experiencing light- and...

Using a parasite pest to create bioluminescent wood
29.11.2024 | Press monitoring
In order to defy climate change and the bark beetle, more deciduous trees are being planted in Swiss forests. If possible, their wood should be used several times before it ends up as firewood, thus releasing the previously bound CO? back into the atmosphere. At present, however, hardwood is still too often used directly for heating. One...
Molecular morphers: DNA-powered gels shape-shift on command
27.11.2024 | Press monitoring
Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These "gel automata," measuring just centimeters, can grow or shrink, transforming from one letter or number to another when triggered by specific DNA molecules. This breakthrough opens possibilities for shape-shifting...

Using gas bubbles to precisely deliver nanomedicines shows promise for lung cancer treatment
25.11.2024 | Press monitoring
The delivery of nanomedicines using gas bubbles has shown itself to be a unique way of transporting cytotoxins to the lungs of cancer patients. The method enables precise and focused treatments, and the local action of the drugs also prevents a range of side-effects. Results from SINTEF's experiments with mice have shown that the impact of this...

This spaghetti is so thin it can\'t be photographed with a regular camera
22.11.2024 | Press monitoring
No, you can't eat the world's thinnest spaghetti. It's 200 times thinner than a human hair, which means you'd have a hard time spotting it on a plate and an even harder time cooking it. So why make it? Researchers at University College London (UCL) developed nanoscale threads from a mixture of flour and liquid in an effort to create porous...

Nanofibers made of copper-binding peptides disrupt cancer cells
20.11.2024 | Press monitoring
While toxic in high concentrations, copper is essential to life as a trace element. Many tumors require significantly more copper than healthy cells for growth – a possible new point of attack for cancer treatment. Research team from the Max Planck Institute for Polymer Research has now introduced a novel method by which copper is effectively...

Antarctic bacteria show promise as biocontrol agents for combating banana wilt
18.11.2024 | Press monitoring
A recent study conducted by scientists at ESPOL has unveiled the biotechnological potential of microorganisms from Antarctica. In this remote continent, where life thrives under extreme conditions, researchers isolated 77 microbial strains from 162 cultures, identifying 49 species, predominantly actinomycetes (66.23%). Sampling conducted at the...
