US Scientists Find A New Method To Grow Food Without Sunlight

Image
Photosynthesis is a process in which plants use sunlight's energy to produce their food from water and carbon dioxide. But this process is very ineffective, with only 1 percent of the energy found in sunlight ending up in the plant. Image Credits: Pixabay Researchers at the University of California, Riverside (UCR) and the University of Delaware have improved the natural process of photosynthesis and found a new method of growing plants in darkness using artificial photosynthesis. This artificial photosynthesis could enhance agriculture in areas that don't get receive sufficient sunlight, help feed future space and support humankind to grow plants on Mars, the red planet. The researchers used a two-step electro catalytic process to convert electricity, water and carbon dioxide into acetate, a form of vinegar's main component. This acetate was then consumed by food-producing plants to grow in the dark. Researchers discovered that using solar panels to generate electricity

When will Pluto Complete Its First Orbit Around the Sun Since Discovery?

Image
NASA’s New Horizons spacecraft took this enhanced-colour image of Pluto on July 14, 2015. (Image credit: NASA/JHUAPL/SwRI) It will take some time before astronomers can celebrate Pluto's first complete orbit since its discovery. On February 18, 1930, Pluto was found using the Lowell Observatory in Flagstaff, Arizona. Clyde Tombaugh , an American astronomer, discovered a moving object unmistakably outside Neptune's orbit. Pluto, the lord of the Greek underworld in mythology, was the name given to that item later. Pluto's status as a planet or a dwarf planet has been the subject of a protracted argument. However, scientists believe that since Tombaugh discovered Pluto in images, the planet hasn't made a single round around the sun. Pluto's orbit around the sun takes 248.09 Earth years to complete. When you enter that data and the date of Pluto's discovery into a timeanddate.com calculator, you'll learn that the planet will complete its first complete orbit si

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). Image credits: Pixabay The Problem With Wound Healing And Its Solution Currently, there are 3000 types of wound healing dressings available for numerous types of wounds. 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
