Indian Researchers Develop a Biodegradable Advanced Wound Healing Bandage With Anti-Bacterial And Anti-Inflammatory Properties

Image
Researchers at the Indian Institute of Technology, Bombay (IITB) have developed an affordable bilayered bandage that has antibacterial and anti-inflammatory properties to prevent infections in wounds, Research Matters reported. The top layer consists of chitosan (a type of sugar found in the outer skeleton of a shellfish) and polycaprolactone (a biodegradable polyester). The bottom layer is built of soluble eggshell membrane protein and polyvinyl alcohol (a water-soluble synthetic polymer) in combination with curcumin nanoparticles (an anti-inflammatory compound found in plants of the turmeric family).

However, wounds such as pressure and venous ulcers, diabetic wounds, and burn wounds are difficult to treat with these dressings. In the case of acute and chronic wounds, the skin doesn't repair due to the poor an

German Scientists Find Tetraneutron: An Elusive And Non-native Matter

Image
Researchers at the Technical University of Munich (TUM), Germany , have found evidence for the existence of a foreign and indistinct type of matter containing four neutrons that bind together. The indications of the presence of such a tetraneutron were first observed in an experiment 20 years ago. But the new approach was more accurate and clearer. Image Credits: Pixabay All matter consists of neutrons, but neutron stars contain matter that is made of particles which are bound together by strong nuclear forces. However, it is still unknown what is the exact structure of this neutron. In 2002, the research team discovered some facts that tetraneutrons are the result of the collision between carbon and beryllium atoms. Many nuclear physicists were amazed by this outcome, but they were unable to give scientific explanations behind the experiments. Researchers performed a different particle collision to find solid evidence of a tetraneutron. “We formed something like the smallest neutron

Vitamin D-producing DNA Molecules Can Treat Cancer, Say A Japanese Study

Image
Researchers at Kanazawa University, Japan , have discovered a novel DNA molecule that can inhibit cancerous growth by preventing the breakdown of Vitamin D. The molecule, Apt-7 – a deoxyribonucleic acid (DNA) can bind to other molecules and show anti-cancerous effects. It inhibits the production of the CYP24 enzyme, a protein involved in Vitamin D3 breakdown. Image Credits: Pixabay Previous research has shown that Vitamin D3 helps in building strong bones, but it also displays anti-cancer properties . High levels of it are associated with vigorous and faster recovery of cancer patients. Additionally, it has been spotted as a significant target for cancer treatment due to its relationship with tumour development and progression. Evidence-based research has shown that cancerous cells use this vitamin differently compared to normal cells. Preventing the breakdown of Vitamin D can reduce tumour growth. Further, low levels of CYP24 enzyme are also significant in killing cancer cells. Inhi

Plant-based Antimicrobial Food Wrap Could Be The Plastic Alternative We Desperately Need

Image
Researchers at Rutgers University, in the U.S., have developed a plant-based biodegradable coating or food wrap that can protect edibles against pathogens. This can reduce the use of plastic packaging materials on food and prevent humans from its harmful effects. Image Credits: Pixabay "We knew we needed to get rid of the petroleum-based food packaging that is out there and replace it with something more sustainable, biodegradable and nontoxic," said Philip Demokritou , director of the Nanoscience and Advanced Materials Research Center. "And we asked ourselves at the same time, 'Can we design food packaging with a functionality to extend shelf life and reduce food waste while enhancing food safety?''' The making of the food wrap Researchers used a new packaging technology, focused rotary jet spinning, that converts polysaccharide/biopolymer-based fibres into a solid wrap. The fibres produced using this process can be degraded in the soil within three day

Prevent Harmful Hospital Infections Without Antibiotics? A New Surface Treatment Could Achieve That

Image
A clinic or hospital is a place where the chances of getting an infection are higher. Evidence suggests that medical instruments like pacemakers, heart valves, catheters and stents get coated with harmful bacterial films. These hospital regulars are the primary source of hospital-based infections , accounting for two-thirds of all cases. Image Credits: Pixabay Researchers at the University of California, Los Angeles (UCLA) have developed a new surface treatment that will enhance the safety of these instruments without increasing any financial strain on the healthcare system. The new method has been tested in both clinical and laboratory settings. In this technique, a thin layer of zwitterionic material (polymer having cations and anions) is deposited on the surface of the instrument and this layer is permanently bonded with it with the help of ultraviolet light irradiation. This layer helps to prevent germs from sticking to the surface. Researchers applied this surface treatment to v

US Scientists Are Unable To Locate California's Bumble Bees

Image
Previous studies have reported that there is a decline in several species of California bumble bees around the globe due to expansion of wild habitat, climate changes and use of bee-killing pesticides. A recent court ruling could save them if they can be found. Image Credits: Pixabay Researchers at the University of California, Riverside (UCR) , have proposed a study that suggests there are changes in the populations of bumble bees across the terrestrial areas in California. Bumble bees are adaptive to cooler temperatures and can fly in lower light levels than other bees. They can perform various types of pollination processes required for plants, including peppers, cranberries and tomatoes. Bumble bees pollinate crops worth $3 billion yearly in the US. For the new data, Hollis Woodard , a UCR Entomologist and her team members collected bees from 17 sites representing six different ecosystems earlier known to host a variety of bumble bees. The research team aimed to gather at four plac

Most People On The Planet Don't Want To Become Rich, Finds British Survey

Image
Researchers at the University of Bath, England, have found that the majority of the world's population doesn't want billions of dollars to live their dream life. However, they have found few people who want to become billionaires- which they feel is good for the world. The team stated that there had been a long-economic belief that unlimited desires motivate people on the planet. This keeps them running on a "consumerist treadmill" to earn more for their families. As society still revolves around this thought, researchers believe this affects the stability and health of the population. A never-ending economic growth may end up in more fortune, but at the cost of natural resource depletion and human health. Image Credits: Pexels About the survey The research team wanted to see whether the population wanted to have things that society wanted them to have. They surveyed approximately 8000 people in 33 countries spanning six continents to know how much money people neede
