| What the nose doesn't know helps wildlife: Using olfactory cues to protect vulnerable species Posted: 21 Jun 2022 01:33 PM PDT Behavioral ecologists have discovered a way to harness animals' olfactory ability to protect vulnerable plants and endangered animals. |
| SeqScreen can reveal 'concerning' DNA Posted: 21 Jun 2022 11:17 AM PDT Computer scientists have developed a program to screen short DNA sequences, whether synthetic or natural, to determine their toxicity. |
| Genetic mutations enable efficient evolution of TB-causing bacteria Posted: 21 Jun 2022 08:47 AM PDT Researchers have identified how the bacterium that causes tuberculosis (TB) can evolve rapidly in response to new environments. |
| Remote sensing helps track carbon storage in mangroves Posted: 21 Jun 2022 07:56 AM PDT Researchers have developed a model that can estimate the productivity of mangrove forests at large scales. A remote sensing-based productivity model that considered the effects of tidal inundation was developed. Comparisons with carbon measurements from carbon flux towers showed that the model was able to accurately estimate the productivity of mangrove forests in China. The results highlight the potential of this type of model for assessing the capacity of mangrove forests to store carbon. |
| Wildlife--human conflicts could shift with climate change Posted: 21 Jun 2022 07:56 AM PDT Researchers modeled the risk of human -- elephant conflict in Thailand under different climate change scenarios using a risk framework. A spatial shift in the risk of conflict was observed with climate change, with northern areas and higher latitudes showing increasing risk in the future. These results can be used to develop planning strategies in affected communities and increase coexistence awareness. |
| A blueprint for life forms on Mars? Posted: 21 Jun 2022 07:56 AM PDT Microbes taken from surface sediment near Lost Hammer Spring, Canada, about 900 km south of the North Pole, could provide a blueprint for the kind of life forms that may once have existed, or may still exist, on Mars. |
| Vital cell machinery behind the human body's incorporation of selenium observed Posted: 20 Jun 2022 05:49 PM PDT Scientists have determined the process for incorporating selenium -- an essential trace mineral found in soil, water and some foods that increases antioxidant effects in the body -- to 25 specialized proteins, a discovery that could help develop new therapies to treat a multitude of diseases from cancer to diabetes. |
| Posted: 20 Jun 2022 05:49 PM PDT Some people who experience heart failure have less biodiversity in their gut or have elevated gut metabolites, both of which are associated with more hospital visits and greater risk of death, according to a systematic review of research. |
| A rare discovery of long-term memory in wild frog-eating bats Posted: 20 Jun 2022 09:24 AM PDT Frog-eating bats trained by researchers to associate a phone ringtone with a tasty treat were able to remember what they learned for up to four years in the wild, new research has found. |
| Fifth of global food-related emissions due to transport Posted: 20 Jun 2022 09:23 AM PDT Food transport constitutes 19 percent of food emissions, equivalent to 6 percent of emissions from all sources. High-income countries are responsible for nearly half of these emissions, leading researchers to conclude that among the rich, eating locally should be prioritised. |
| Scientists develop antimicrobial, plant-based food wrap designed to replace plastic Posted: 20 Jun 2022 09:21 AM PDT Aiming to produce environmentally friendly alternatives to plastic food wrap and containers, a scientist has developed a biodegradable, plant-based coating that can be sprayed on foods, guarding against pathogenic and spoilage microorganisms and transportation damage. The scalable process could potentially reduce the adverse environmental impact of plastic food packaging as well as protect human health. |
| Posted: 20 Jun 2022 07:08 AM PDT Species have intrinsic value, but also provide ecosystem services of major economic value, for example, bees that pollinate our crops. However, as such values are hard to translate into figures, currently, they remain easy to dismiss altogether. In a new study, a research team conceptualizes a species stock market for unified valuation of all species. By using digitized information from museums, occurrence data, and DNA sequence databases, this market quantifies our knowledge of each species from scientific, societal, and economic points of view. |
| Evolutionary biology: The greening ashore Posted: 20 Jun 2022 07:08 AM PDT A team has been studying the current state of research on the plant colonization of land that occurred some 500 million years ago. |
| Why vaccination against malaria quickly loses its protective effect Posted: 17 Jun 2022 07:18 AM PDT Scientists have studied the human immune response after immunization with the malaria pathogen Plasmodium falciparum. Their findings could explain why natural infections, to which people in endemic areas are constantly exposed, offer little protection against new diseases with other strains, and why the effect of the vaccination available to date lasts only a short time. |
| The benefits of exercise in a pill? Science is closer to that goal Posted: 15 Jun 2022 08:32 AM PDT Researchers have identified a molecule in the blood that is produced during exercise and can effectively reduce food intake and obesity in mice. |
| Urgent action needed on English Bulldog breeding, experts say Posted: 15 Jun 2022 07:29 AM PDT English Bulldogs must be bred with more moderate physical features, experts say, as a new study reports that the breed is significantly less healthy than other dog breeds. English Bulldogs are at increased risk of breathing, eye, and skin conditions due to their extreme physical features, including shortened muzzles, folded skin, and a squat body, reports a recent article. |
