Agriculture needs fresh approach to tackle insect resistance to biopesticides, new analysis finds
Publicado em
Insect pests which attack crops have extraordinary powers to develop resistance to greener pesticides and a new way to manage resistance risks is needed, according to analysis by University of Stirling scientists.
For more than 70 years, agriculture’s response to pesticide resistance has been to seek new pesticides in an endless race to keep up with evolving pests.
Researchers now propose a new way to step off this treadmill as farmers embrace the ongoing green revolution in pest [...]

Findings may represent promising strategies for promoting muscle function during aging
Publicado em 08 janeiro 2023Proven to protect against a wide array of diseases, exercise may be the most powerful anti-aging intervention known to science. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship among exercise, fitness and aging remain poorly understood. In a paper published in the Proceedings of the National Academy of Sciences, researchers at Joslin Diabetes Center investigated the role of one [...]ver notícia -
Snake venom complexity is driven by prey diet
Publicado em 20 abril 2021Diversity in diet plays a role in the complexity of venom in pit vipers such as rattlesnakes, copperheads and cottonmouths. But new collaborative research by Clemson University scientists found the number of prey species a snake ate did not drive venom complexity. Rather, it was how far apart the prey species were from each other evolutionarily. “It’s not just diet that drives the variation in venom across snakes. It’s the breadth of diet,” said Christopher Parkinson, [...]ver notícia -
Scientists also find two new, nearly 2-million-year-old specimens–likely the earliest pieces of the H. erectus skeleton yet discovered — ScienceDaily
Publicado em 13 abril 2021A new study verifies the age and origin of one of the oldest specimens of Homo erectus — a very successful early human who roamed the world for nearly 2 million years. In doing so, the researchers also found two new specimens at the site — likely the earliest pieces of the Homo erectus skeleton yet discovered. Details are published today in the journal Nature Communications. “Homo erectus is the first hominin that we know about that has a body plan more like our own and [...]ver notícia -
New Ethylene Sensor to Prevent Spoilage of Fruits and Vegetables
Publicado emFlowers and fruits emit a colorless and sweet-smelling gas, known as ethylene, as they bloom and ripen. To test the new sensor’s capabilities, the researchers deposited the carbon nanotubes and other sensor components onto a glass slide. They then used it to monitor ethylene production in two types of flowers—red carnations and purple lisianthus. Image Credit: Stock imagery edited by MIT News. Chemists at Massachusetts Institute of Technology (MIT) have developed a miniature [...]ver notícia -
Novel techniques for mining patented gene therapies offer promising treatment options
Publicado em 10 fevereiro 2020The global gene therapy market is expected to reach $13 billion by 2024 as new treatment options target cancers and other diseases. Now, a team of scientists from Purdue University and other research institutions around the world have come together to better understand the growing number of worldwide patented innovations available for gene therapy treatment. They specifically focus on nonviral methods, which use synthetic or natural compounds or physical forces to deliver materials generally [...]ver notícia -
New compound can inhibit malaria parasite growth: Study
Publicado em 05 novembro 2019An international team of researchers have found that a novel compound can halt the growth of the parasite Plasmodium falciparum known to cause malaria — the deadly mosquito-borne disease which kills nearly 500,000 people every year across the world. The study, published in the journal Science, noted that the compound called TCMDC-135051 developed by the multinational pharmaceutical company GlaxoSmithKline can eliminate the mosquito-borne parasite in all the stages of its lifecycle. The [...]ver notícia
