| Methane in plumes of Saturn's moon Enceladus: Possible signs of life? Posted: 06 Jul 2021 03:09 PM PDT A study concludes that known geochemical processes can't explain the levels of methane measured by the Cassini spacecraft on Saturn's icy moon. While the paper by no means suggests that life exists on Enceladus, the results would be consistent with microbial activity similar to that known to occur at hydrothermal vents in Earth's oceans. |
| Secret to weathering climate change lies at our feet Posted: 06 Jul 2021 01:38 PM PDT Researchers recently discovered that the ability of agricultural grasses to withstand drought is directly related to the health of the microbial community living on their stems, leaves and seeds. |

| Worms learn how to optimize foraging by switching their response to social cues Posted: 06 Jul 2021 12:30 PM PDT Worms optimize their foraging behavior by learning to associate pheromones with food availability and changing their movements accordingly, new research finds. |
| Bacterial survival kit to endure in soil Posted: 06 Jul 2021 10:31 AM PDT Soil bacteria have amazing strategies to attain energy in order to withstand stressful times. Researchers investigated how acidobacteria, which are widespread in soils, can survive under adverse conditions. |
| Posted: 06 Jul 2021 10:31 AM PDT Researchers have developed an innovative material that is eco-friendly, completely biological and non-toxic, and causes no harm to the body's tissues. The material is as strong as titanium and extremely flexible. The new development will allow for the charging of pacemakers using only the heartbeat, eliminating the need for batteries. The new material will make it possible to produce green energy activated by mechanical force that can be applied to other areas as well. |
| New species of pseudo-horses living 37 million years ago Posted: 06 Jul 2021 10:31 AM PDT Scientists have described two new species of palaeotheriidae mammals that inhabited the subtropical landscape of Zambrana (Álava) about 37 million years ago. Their atypical dental features could point to a difference in environmental conditions between the Iberian and Central European areas. |
| Relationship between chromosomal instability and senescence revealed in the fly Drosophila Posted: 06 Jul 2021 10:31 AM PDT Researchers have revealed the mechanisms by which cells enter senescence because of an imbalance in the number of chromosomes. Chromosomal instability is a common trait in most solid tumors, such as carcinoma, and fully understanding its relationship with cancer can help identify new therapeutic targets. |
| Sexual reproduction without mating Posted: 06 Jul 2021 08:54 AM PDT A type of fungi studied by a team of biologists for their sexual reproduction strategies are commonly known as Sword-belt Mushrooms. In addition to the European Sword-belt Mushroom (Cyclocybe aegerita), its Pacific relative, the so-called Tawaka (Cyclocybe parasitica), also possesses the unusual ability for agarics to single-handedly form complex multicellular structures for sexual reproduction. These fruiting bodies are normally produced as a collaborative effort between two sexual partners. |
| Study finds genes role in immune response of Florida corals to rapidly spreading disease Posted: 06 Jul 2021 08:54 AM PDT A new study has documented what coral genes are doing in response to a disease that is rapidly killing corals throughout Florida and the Caribbean. The findings can help to better understand coral immune system as new diseases emerge as the ocean warm. |
| Next-generation sequencing uncovers what's stressing bumblebees Posted: 06 Jul 2021 08:53 AM PDT Scientists used next-generation sequencing to look inside bumblebees for evidence of pesticide exposure, including neonicotinoids, as well as pathogens, and found both. Using a conservation genomic approach, the researchers studied Bombus terricola or the yellow-banded bumblebee, a native to North America, in agricultural and non-agricultural areas. This new technique allows scientists to probe for invisible stressors affecting bees. |
| The brain's wiring technicians Posted: 06 Jul 2021 08:53 AM PDT Research in mice reveals how a subset of highly specialized immune cells modulate brain wiring by precision-targeting inhibitory synapses. The work deepens understanding of the versatile repertoire of microglia, the brain's immune cells and resident garbage collectors. The results set the stage for the development of therapies for neurodevelopmental and psychiatric conditions marked by defects in synaptic function. |
| New signaling pathway could shed light on damage repair during brain injury Posted: 06 Jul 2021 08:53 AM PDT An observational study conducted using Drosophila fruit flies has uncovered a signaling pathway that causes neural cells to enter divisions after damage. The research is important because the signaling kinases are also seen activated in human Alzheimer's brain neurons post mortem. The next step is to identify whether the pathway happens in the same way in human neurons, and whether it can be stopped. |
| Sharp size reduction in dinosaurs that changed diet to termites Posted: 06 Jul 2021 08:53 AM PDT Dinosaurs were generally huge, but a new study of the unusual alvarezsaurs show that they reduced in size about 100 million years ago when they became specialized ant-eaters. |
| Scientists rejuvenate mouse brains with ketamine or flickering light Posted: 06 Jul 2021 08:53 AM PDT In defining periods of development, the brain re-organizes connections between its neurons more freely than in its adult form. Researchers have now discovered two methods to reopen such plasticity: repeated ketamine anesthesia and non-invasive 60 hertz light flickering. The findings may have the potential to become a therapeutic tool applicable to humans. |
| A protein complex from plant stem cells regulates their division and response to stress Posted: 06 Jul 2021 08:53 AM PDT Researchers have discovered that two proteins, which are involved in the control of stem cells' division in plant roots, need each other for these cells to function properly. The study combines experimental work with plants and mathematical modeling. The mechanism provides knowledge that could be useful, for agriculture and for the design of efficient strategies in medicine and cosmetics that slow down cellular aging. |
| New fossil sheds light on evolution of how dinosaurs breathed Posted: 06 Jul 2021 08:53 AM PDT An international team of scientists has used high-powered X-rays at the European Synchrotron to show how an extinct South African 200-million-year-old dinosaur, Heterodontosaurus tucki, breathed. |
| Vertical greenery can act as a stress buffer Posted: 06 Jul 2021 08:53 AM PDT Vertical greenery 'planted' on the exterior of buildings may help to buffer people against stress, a new study has found. |
| Light pollution has complex effects on animal vision Posted: 06 Jul 2021 07:20 AM PDT Changes in the color and intensity of light pollution over the past few decades result in complex and unpredictable effects on animal vision, new research shows. |
| High-throughput metabolic profiling of single cells Posted: 06 Jul 2021 07:19 AM PDT Scientists have presented a new method for generating metabolic profiles of individual cells. The method, which combines fluorescence microscopy and a specific form of mass spectroscopy, can analyze over a hundred metabolites and lipids from more than a thousand individual cells per hour. Researchers expect the method to better answer a variety of biomedical questions in the future. |
| Male dragonflies lose their 'bling' in hotter climates Posted: 05 Jul 2021 12:21 PM PDT A new study finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates. The research reveals that mating-related traits can be just as important to how organisms adapt to their climates as survival-related traits. |
