Scientists engineer plants to speak in color as environmental sensors for dangerous chemicals

30.10.2023   |   Press monitoring

UC Riverside researchers had to solve an engineering puzzle: how to enable a plant to sense and react to a chemical in the environment without damaging its ability to function normally in all other respects. Last year the research team demonstrated that ABA receptor proteins can be trained to bind to chemicals other than ABA. Now the team has...

Finding the genes that help kingfishers dive without hurting their brains

27.10.2023   |   Press monitoring

If you've ever belly-flopped into a pool, then you know: water can be surprisingly hard if you hit it at the wrong angle. But many species of kingfishers dive headfirst into water to catch their fishy prey. In a new study in the journal Communications Biology, researchers compared the DNA of 30 different kingfisher species to zero in on the genes...

International team develops novel DNA nano engine

25.10.2023   |   Press monitoring

An international team of scientists has recently developed a novel type of nano engine made of DNA. It is driven by a clever mechanism and can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a drive in complex nano machines. Petr Šulc, an assistant professor at Arizona State University's...

Material made of live glowing algae could be used in stress sensors

23.10.2023   |   Press monitoring

Whether they're in machines, buildings or aircraft, it's always helpful to know if components are undergoing mechanical stress. A new material could quickly and easily let inspection personnel know, utilizing integrated glowing algae. Developed by scientists at the University of California - San Diego, the experimental substance is made mainly...

Gene-edited chickens in the fight against bird flu

20.10.2023   |   Press monitoring

Scientists have used gene editing techniques to identify and change parts of chicken DNA that could limit the spread of the bird flu virus in the animals. Researchers were able to restrict – but not completely block – the virus from infecting chickens by altering a small section of their DNA. The birds showed no signs that the change in their DNA...

Researchers develop organic nanozymes suitable for agricultural use

18.10.2023   |   Press monitoring

Nanozymes are synthetic materials that mimic the properties of natural enzymes for applications in biomedicine and chemical engineering. Historically, they are generally considered too toxic and expensive for use in agriculture and food science. Now, researchers from the University of Illinois Urbana-Champaign have developed a nanozyme that is...

Bacteria-based cancer therapy reactivates vaccines you\'ve already had

16.10.2023   |   Press monitoring

Vaccines against cancer are somewhat of a holy grail for medicine – but what if you could repurpose a vaccine you’ve already had? Scientists have demonstrated in mice a way to trick the immune system into attacking tumors by mistaking them for a pathogen it’s already developed a response against. Generally, vaccines work by stimulating the immune...

New organ-on-a-chip provides hope to arthritis sufferers

13.10.2023   |   Press monitoring

Researchers have developed a 3D organ-on-a-chip, complete with blood vessels, that mimics the human joint. The discovery will help researchers understand the pathology of joint diseases better and assist with the identification and testing of new treatments for arthritis. Arthritic joint diseases, such as rheumatoid arthritis and osteoarthritis,...

Plasma tech transforms blue-green algae into a wound-healing wonder

11.10.2023   |   Press monitoring

Plasma is formed from gas so superheated that the electrons are ripped away from the atoms, resulting in a soup of positively charged ions and negatively charged electrons. An atmospheric pressure plasma jet (APPJ) provides a plasma discharge at ambient pressure using a noble gas/molecular gas mixture passed through a powerful electric arc...

Study of more than 330,000 genomes indicates 34 genes potentially involved in vegetarianism

9.10.2023   |   Press monitoring

Certain variations in genes involved in lipid metabolism and brain function may be associated with choosing a vegetarian diet, according to a new study led by Nabeel Yaseen of Northwestern University. A small percentage of the population chooses to eat a vegetarian diet for a variety of religious, ethical, environmental, and health-related...
