| Switching from Western diet to a balanced diet may reduce skin, joint inflammation Posted: 22 Jun 2021 01:10 PM PDT Diet rich in sugar and fat leads to disruption in the gut's microbial culture and contributes to inflammatory skin diseases such as psoriasis. Research shows that switching to a more balanced diet restores the gut's health and suppresses inflammation. |
| Antelope's fate shrouded by social, political forces Posted: 22 Jun 2021 12:43 PM PDT The story of efforts to conserve the endangered oribi in South Africa represent a diaspora of issues as varied as the people who live there. |
| Some seafloor microbes can take the heat: And here's what they eat Posted: 22 Jun 2021 12:43 PM PDT In two new studies on life in the seafloor of the Guaymas Basin, in the Gulf of California, scientists show that distinct regions within the Basin harbor specially adapted microorganisms; discover new microbial inhabitants of this deep-sea community; and suggest how the community may be dramatically influencing carbon cycling in the hot seafloor sediments. |
| Posted: 22 Jun 2021 11:28 AM PDT The nucleus is much more than a storage compartment for chromosomes: It also contains the complex machinery producing transcripts of the genes that are currently needed and releases them into the cell body. Some of the proteins involved herein are not evenly distributed in the nucleus, but cluster at specific sites. A study now shows how these 'flash mobs' are regulated. |
| Ready, set, go - how stem cells synchronize to repair the spinal cord in axolotls Posted: 22 Jun 2021 09:53 AM PDT Few animals can regenerate their spinal cord after an injury. The axolotl can mobilize stem cells in its spinal cord to regrow the lost tissue. An international team of scientists have investigated the early stages of this process. |
| Did the ancient Maya have parks? Posted: 22 Jun 2021 09:53 AM PDT Researchers developed a novel system to analyze ancient plant DNA in the sediment of Tikal's temple and palace reservoirs to identify more than 30 species of trees, grasses, vines and flowering plants that lived along its banks more than 1,000 years ago. Their findings paint a picture of a lush, wild oasis in the ancient Maya city. |
| Salt marsh plants may signal carbon capture capacity Posted: 22 Jun 2021 09:33 AM PDT Coastal wetlands like seagrass meadows, mangroves, and salt marshes play vital roles along the shoreline, from providing a buffer against storm surges, to providing critical habitat for animals, to capturing atmospheric carbon. We are still just beginning to comprehend the intricate workings of these highly productive ecosystems and their role in mitigating the climate crisis, but researchers are one step closer to understanding how salt marsh vegetation, their bacterial communities, and vegetation can help predict a marsh's potential to be a blue carbon reservoir. |

| Crab species found to have asymmetrical male and female reproductive structures Posted: 22 Jun 2021 09:33 AM PDT Researchers have recently identified and described a new genus and species of xanthid crab found in Okinawa Island, Ryukyu Islands, Japan. Named Mabui calculus, it is the first among the 7,800 species of known crabs to have strongly asymmetrical male and female reproductive structures. |
| Mushroom growing out of fossilized ant reveals new genus and species of fungal parasite Posted: 22 Jun 2021 09:33 AM PDT Oregon State University research has identified the oldest known specimen of a fungus parasitizing an ant, and the fossil also represents a new fungal genus and species. |
| Cohesin opens up for cell division Posted: 22 Jun 2021 09:33 AM PDT Scientists have uncovered a mechanism that allows a protein complex to bind to DNA without impeding some of the important processes of cell division. Their findings could further understandings of developmental disorders arising from mutations in the gene that codes for the complex. |
| Boost for mouse genetic analysis Posted: 22 Jun 2021 09:33 AM PDT To understand what role an individual gene plays, biologists have, for 100 years, been using a trick of nature: While in principle, the genome in all cells of an organism is the same, mutations arise in individual cells. These mutations differentiate a cell from its neighbors, forming a 'genetic mosaic.' Now, researchers have advanced genetic mosaic analysis, making almost all genes in the mouse genome accessible to single-cell genetic mosaic analysis. |
| Illuminating the mechanism behind how plants regulate starch synthesis Posted: 22 Jun 2021 09:33 AM PDT Biologists have used rice to successfully illuminate the mechanism by which plants regulate the amount of starch produced via photosynthesis. This knowledge could contribute towards improving the quality and yield of agricultural crops. |
| Venomous caterpillar has strange biology Posted: 22 Jun 2021 09:33 AM PDT The venom of a caterpillar, native to South East Queensland, shows promise for use in medicines and pest control, researchers say. |
| Producing hydrogen using less energy Posted: 22 Jun 2021 09:32 AM PDT The way in which a compound inspired by nature produces hydrogen has now been described in detail. These findings are the foundation for the energy-efficient production of hydrogen as a sustainable energy source. |
| The humidity of flowers acts as an invisible attractor for bumblebees Posted: 22 Jun 2021 09:32 AM PDT As well as bright colors and subtle scents, flowers possess many invisible ways of attracting their pollinators, and a new study shows that bumblebees may use the humidity of a flower to tell them about the presence of nectar. |
| 'Urban green space affects citizens' happiness' Posted: 22 Jun 2021 06:53 AM PDT A recent study revealed that as a city becomes more economically developed, its citizens' happiness becomes more directly related to the area of urban green space. |
| Engineering nanobodies as lifesavers when SARS-CoV-2 variants attack Posted: 22 Jun 2021 06:53 AM PDT Scientists are pursuing a new strategy in the protracted fight against the SARS-CoV-2 virus by engineering nanobodies that can neutralize virus variants in two different ways. |
| A 'bio-refinery': Using the chemistry of willow trees to treat municipal wastewater Posted: 22 Jun 2021 06:53 AM PDT Millions of liters of primary municipal wastewater can be treated sustainably using fast-growing willow trees while also producing renewable bioenergy and 'green' chemicals, researchers find. |
| Worrying insights into the chemicals in plastics Posted: 22 Jun 2021 06:16 AM PDT ETH researchers examined chemicals in plastics worldwide. They found an unexpectedly high number of substances of potential concern intentionally used in everyday plastic products. A lack of transparency limits management of these chemicals. |
| Unchecked climate change will cause severe drying of the Amazon forest Posted: 22 Jun 2021 06:16 AM PDT Amazon rain forests could be at far higher risk of extreme drought than previously thought, according to new research. |
| Bee-impersonating flies show pollinator potential Posted: 22 Jun 2021 06:16 AM PDT An observational study found that out of more than 2,400 pollinator visits to flowers at urban and rural farms in in Western Washington about 35% of were made by flies -- most of which were the black-and-yellow-striped syrphid flies. For a few plants, including peas, kale and lilies, flies were the only pollinators observed. Bees still made the majority, about 61%, of floral visits, but the rest were made by other insects and spiders. |
| Metal catalysts used for environmental sustainability found to degrade and become less effective Posted: 22 Jun 2021 06:16 AM PDT New research is showing that some tiny catalysts being considered for industrial-scaled environmental remediation efforts may be unstable during operation. |
| Analysing volcanoes to predict their awakening Posted: 22 Jun 2021 06:16 AM PDT A team has reviewed the literature on the internal and external mechanisms that lead to a volcanic eruption. Analyzing the thermo-mechanics of deep volcanic processes and magma propagation to the surface, together with magma chemistry, the geologists determined that most of the magma rising from depth actually does not cause a volcanic eruption. They also show that older volcanoes tend to produce less frequent, but larger and more dangerous eruptions. |
| No northern escape route for Florida's coral reefs Posted: 22 Jun 2021 06:16 AM PDT Warming seas are driving many species of marine life to shift their geographic ranges out of the tropics to higher latitudes where the water is cooler. Florida's reefs will not be able to make that northward move, however, as they will be caught between intolerably hot tropical waters and increasingly frequent water-cooling cold snaps, according to new findings. |
| Aviation's contribution to cutting climate change likely to be small Posted: 22 Jun 2021 06:16 AM PDT Although the emissions targets for aviation are in line with the overall goals of the Paris Agreement, there is a high likelihood that the climate impact of aviation will not meet these goals, according to a new study. |
| A warming climate and intensifying land use increase mercury content in fish Posted: 22 Jun 2021 06:16 AM PDT Recent studies show that, in the future, the mercury concentration of fish in Finnish Lapland can shift closer to the level found in lakes located below the Arctic Circle. According to researchers, mercury content should be increasingly carefully investigated and monitored in fish and food webs, as the climate and land use change. |
| Tradition of keeping mementos in memory of loved ones dates back at least 2,000 years, study shows Posted: 21 Jun 2021 05:24 PM PDT A new study suggests that mundane items like spoons and grinding stones were kept by Iron Age people as an emotional reminder and a 'continuing bond' with the deceased -- a practice which is replicated in societies across the globe today. |
| Butterflies regularly cross the Sahara in longest-known insect migration Posted: 21 Jun 2021 02:41 PM PDT Wetter conditions in Sub-Saharan and North Africa at certain times of year can result in hundreds of times more Painted Lady butterflies making the 14,000 km round trip to Europe. Findings improve understanding of how insects move to other countries, including pests that destroy crops and disease-carrying species like mosquitoes. |
| Lead from leaded petrol persists in London air despite '90s ban Posted: 21 Jun 2021 01:05 PM PDT Lead levels in London's atmosphere have dropped drastically since lead additives in petrol were phased out, and currently meet UK air quality targets. However despite this drop, airborne particles in London are still highly lead-enriched compared to natural background levels, according to new research. |
| Females supercharge sperm evolution in animals Posted: 21 Jun 2021 09:38 AM PDT Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job -- to fertilize eggs? Researchers now show that animal sperm evolution become supercharged only when sperm swim inside females. |
