| Fast, efficient COVID-19 biosensor under development Posted: 21 Jul 2022 11:15 AM PDT Researchers are developing a 'biosensing platform' for COVID-19 that's fast, efficient, accurate and highly sensitive, which could help scientists stay on top of shifting virus variants. |
| Taste sensors keep proteins in order in flies Posted: 21 Jul 2022 11:15 AM PDT A set of genes that promote sweet taste sensation is also crucial for protein management during fly development, according to a new study. The finding expands the understanding of a key process in successful development, and suggests a connection between taste-related genes and disorders of protein aggregation. |
| A novel COVID-19 vaccine using modified bacterial DNA Posted: 21 Jul 2022 11:14 AM PDT Researchers describe a different way to build a COVID-19 vaccine, one that would, in theory, remain effective against new and emerging variants and could be taken as a pill, by inhalation or other delivery methods. |
| The outer limits: Future economic growth in the face of diminishing resource Posted: 21 Jul 2022 10:20 AM PDT University of California San Diego Professor of Physics Thomas Murphy believes that although no one can say with absolute certainty that the planet will reach an unavertable crisis by the end of this century, our current trajectory is unable to continue much longer. |
| Medical face mask membrane that can capture, deactivate SARS-CoV-2 spike protein on contact Posted: 21 Jul 2022 10:20 AM PDT SARS-CoV-2 is covered in spike proteins, which allow the virus to enter host cells once in the body. Researchers have developed a membrane that includes proteolytic enzymes that attach to the protein spikes and deactivate them. |
| Sick animals struggle to problem solve and adapt to changing environments Posted: 21 Jul 2022 10:20 AM PDT Even common infections can come with acute or lingering cognitive symptoms; one of the best-known examples is 'COVID fog.' In a new review article, cognitive and disease ecologists discuss how infection-associated decline in learning, memory, or decision making can affect how well animals, such as birds and bees, adapt to urbanization or climate change. |
| Posted: 21 Jul 2022 10:20 AM PDT Macrophages play a central role in our immune response. They can trap and digest invading pathogens. However, specific bacteria such as Salmonella or Mycobacteria can survive the digestive system of macrophages and escape the control of immune cells. Research reveals how different organelle systems communicate to activate a more effective anti-bacterial defense mechanism. Successful elimination of specific bacteria in the phago-lysosomal system depends on a signal controlling mitochondria. The yet unknown phago-lysosome-mitochondria crosstalk in macrophages leads to a better understanding of how immune cells work and may identify new intervention points for treating infectious diseases. |
| Lonely old deers: Aging red deer become less social as they grow older Posted: 21 Jul 2022 10:19 AM PDT A new social network analysis of female wild red deer on the Isle of Rum in Scotland shows that aging deer tend to adopt a life of solitude in their advancing years. |
| Silk offers an alternative to some microplastics Posted: 21 Jul 2022 10:19 AM PDT Researchers developed a biodegradable system based on silk to replace microplastics added to agricultural products, paints, and cosmetics. The processing method is simple and tunable, so the material could be adapted to work on existing manufacturing equipment. |
| Just 10 financial actors hold the key to climate change Posted: 21 Jul 2022 10:19 AM PDT A new report has identified the 10 financial actors with the most influence on the fossil fuel economy and outlines the decisive role they can play in helping de-carbonize our future. |
| Physiological features of Japanese black cattle with high methane production Posted: 21 Jul 2022 07:15 AM PDT Methane emitted from cows is a significant source of greenhouse emissions. Now, a collaborative project has used biomarkers to tell us more about the metabolic and nutritional characteristics linked to enteric methane emissions in Japanese Black cattle. |
| Electric nanomotor made from DNA material Posted: 21 Jul 2022 07:15 AM PDT A research team has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles and converts electrical energy into kinetic energy. The new nanomotors can be switched on and off, and the researchers can control the rotation speed and rotational direction. |
| New physics law could predict genetic mutations Posted: 21 Jul 2022 07:15 AM PDT Genetic mutations could be predicted before they occur using a new law of physics, according to a new study. |
| 'Sensing system' spots struggling ecosystems Posted: 21 Jul 2022 07:15 AM PDT A new 'resilience sensing system' can identify ecosystems that are in danger of collapse, research shows. |
| The birds and the bees -- and the temperature gauge Posted: 21 Jul 2022 07:15 AM PDT Animals will often put their lives on the line for reproduction, even if it comes at the cost of being the wrong temperature. Thermal biology co-adapts with the traits favored by sexual selection, including things like courtship displays, ornamental coloration and enlarged weapons like horns or claws. |
| Feeding dogs raw meat associated with increased presence of antibiotic-resistant bacteria Posted: 20 Jul 2022 04:37 PM PDT New research has revealed an association between the feeding of raw meat to pet dogs and the presence of bacteria resistant to critically important antibiotics. |
| Cellular protein identified as possible drug target to combat Lassa hemorrhagic fever Posted: 20 Jul 2022 12:06 PM PDT Experimental approach could uncover new treatment options for the virus, which is highly prevalent in Western Africa. |
| Putting the brakes on 'budding' viruses Posted: 20 Jul 2022 12:06 PM PDT Paramyxoviruses have the potential to trigger a devastating pandemic. This family of viruses includes measles, Nipah virus, mumps, Newcastle disease and canine distemper. An international team has examined key stage in the life cycles of measles and Nipah viruses. It reveals how future therapies might stop these viruses in their tracks. |
| Study shows widespread mislabeling of CBD content occurs for over-the-counter products Posted: 20 Jul 2022 09:10 AM PDT Researchers tested more than 100 topical cannabidiol (CBD) products available online and at retail stores, and found significant evidence of inaccurate and misleading labeling of CBD content. |
| Data scientists use new techniques to identify lakes and reservoirs around the world Posted: 19 Jul 2022 06:12 AM PDT Data scientists has published a comprehensive global dataset of the lakes and reservoirs on Earth showing how they have changed over the last 30+ years. |
| Australian vulture emerges from fossil record Posted: 19 Jul 2022 06:11 AM PDT Australia's first fossil vulture has been confirmed more than 100 years after it was first described as an eagle. The discovery highlights the diversity of Australian megafauna and other animals many thousands of years ago in the Pleistocene period. |
