| Lab earthquakes show how grains at fault boundaries lead to major quakes Posted: 07 Jun 2022 01:10 PM PDT In a 'seismological wind tunnel,' engineers demonstrate the impact of rock gouge -- ground-up rock along a fault boundary -- on earthquake propogation. |
| Scientists find new indicators of Alaska permafrost thawing Posted: 07 Jun 2022 09:10 AM PDT More areas of year-round unfrozen ground have begun dotting Interior and Northwest Alaska and will continue to increase in extent due to climate change, according to new research. |
| Nano-sensor detects pesticides on fruit in minutes Posted: 07 Jun 2022 09:10 AM PDT Researchers have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique uses flame-sprayed nanoparticles made from silver to increase the signal of chemicals. While still at an early stage, the researchers hope these nano-sensors could help uncover food pesticides before consumption. |
| Targeted micronutrition ameliorates allergy symptoms Posted: 07 Jun 2022 09:10 AM PDT Micronutrient deficiencies can promote inflammation and render the immune system particularly sensitive to allergenic substances. In particular, iron deficiency signals danger to immune cells and leads to a more pronounced, exaggerated immune response. For the first time, scientists have conducted a placebo-controlled trial and showed that targeted dietary measures can reduce the symptom burden in allergic reactions. The researchers are therefore treading a completely new path in the care of allergy sufferers. |
| Death of bats at wind turbines interrupts natural food chains Posted: 07 Jun 2022 09:10 AM PDT The numerous casualties of bats at wind turbines (WT) have a negative impact on the populations of affected species and potentially far-reaching consequences for the biodiversity in rural areas. Until now, it could only be assumed that the death of bats had further consequences. Now, a team of scientists show that natural food chains are interrupted, which can have far-reaching negative consequences for agriculture and forestry. The study demonstrates the extent to which the functional importance of bats for habitats has been underestimated so far. |
| Intriguing connection between diet, eye health and lifespan uncovered Posted: 07 Jun 2022 09:09 AM PDT Researchers have demonstrated a link between diet, circadian rhythms, eye health and lifespan in Drosophila.

| Low levels of high-risk salmonella evade traditional methods of detection Posted: 07 Jun 2022 09:09 AM PDT Poultry is responsible for more than one out of every five cases of salmonella infection in the U.S. But traditional methods of testing the chicken you grab off the grocery shelf may not be enough to detect all strains of the bacteria, according to new research. |
| Data reveal 20-year transformation of Gulf of Maine Posted: 07 Jun 2022 09:09 AM PDT Two decades of research show a startling transformation of the Gulf of Maine. Many trends point to an overarching pattern: more warm, North Atlantic water is coming in and changing the foundation of the Gulf's food web. |
| Lessons from the past: How cold-water corals respond to global warming Posted: 07 Jun 2022 09:09 AM PDT Corals react to changes in their environment. This is true for tropical as well as cold-water corals and includes, among others, changes in temperature, salinity and pH values. Researchers have now investigated how warmer temperatures occurring as a result of climate change are affecting cold-water corals. For this purpose, they examined in detail how these corals have reacted to environmental changes over the past 20,000 years. |
| Earth-abundant solar pixels found to produce hydrogen for weeks Posted: 07 Jun 2022 09:09 AM PDT Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks -- according to new research.

| Scientists develop novel computational model for aptamer generation, with wide applications Posted: 07 Jun 2022 09:07 AM PDT Aptamers are single-stranded oligonucleotides generated by the systematic evolution of ligands by exponential enrichment (SELEX). They have a wide variety of applications, but computational approaches are necessary to efficiently identify candidate aptamers. A team of researchers has now developed RaptGen, a variational autoencoder that efficiently discovers new aptamers not included in the input SELEX dataset. This novel computational model could one day be the standard method for aptamer generation. |
| Deciphering the migratory pattern of the smallest seabird in the Mediterranean Posted: 07 Jun 2022 09:05 AM PDT It had always been thought that the Mediterranean population of the European storm petrel -- the smallest seabird in the Mediterranean -- spent the year in this sea and that only a small part of the population migrated to the Atlantic during the winter season. Now, a study reveals that most of the European storm petrels that nest in the western Mediterranean move to the Atlantic Ocean as their main wintering area. |
| Bacterial cellulose could enable microbial life on Mars Posted: 06 Jun 2022 03:12 PM PDT An international research team has investigated the chances of survival of kombucha cultures under Mars-like conditions. Kombucha is known as a drink, sometimes called tea fungus or mushroom tea, which is produced by fermenting sugared tea using kombucha cultures -- a symbiotic culture of bacteria and yeast. Although the simulated Martian environment destroyed the microbial ecology of the kombucha cultures, surprisingly, a cellulose-producing bacterial species survived. |
| Warning labels could help customers identify hidden sugar in restaurant menus Posted: 06 Jun 2022 03:12 PM PDT Seeing a warning icon on a restaurant menu may help consumers identify the high amounts of added sugar hidden in menu items -- and it may even convince them to reach for healthier items like water, say researchers. |
| How species form: What the tangled history of polar bear and brown bear relations tells us Posted: 06 Jun 2022 03:12 PM PDT A new study is providing an enhanced look at the intertwined evolutionary histories of polar bears and brown bears. Becoming separate species did not completely stop these animals from mating with each other. Scientists have known this for some time, but the new research draws on an expanded dataset -- including DNA from an ancient polar bear tooth -- to tease out more detail. |
| New evidence about when, where, and how chickens were domesticated Posted: 06 Jun 2022 03:11 PM PDT New research transforms our understanding of the circumstances and timing of the domestication of chickens, their spread across Asia into the west, and reveals the changing way in which they were perceived in societies over the past 3,500 years. |
| Gene variation may be early indicator for gastric cancer Posted: 06 Jun 2022 03:11 PM PDT Researchers are hoping to catch stomach cancer before it develops in at-risk patients.

| Vocal non-native songbird could change Britain's dawn chorus as we know it Posted: 06 Jun 2022 08:15 AM PDT A tiny but loud, brightly colored songbird from subtropical Asia could be emerging as a new invasive species in Britain, threatening to dominate the dawn chorus of native Robins, Blackbirds and warblers. A new study warns the Red-billed Leiothrix could become as familiar in gardens, parks and woodland as Ring-necked Parakeets. |
| Posted: 06 Jun 2022 08:15 AM PDT Over 200 years ago, a Spanish botanist described Artocarpus odoratissimus, a species of fruit-bearing tree found in Borneo and the Philippines. The Iban people, who are Indigenous to Borneo, know the tree to have two different varieties, which they call lumok and pingan, distinguished by their fruit size and shape. Despite this knowledge, Western botanists have long considered the tree as a single species, but a genetic analysis confirms the Iban people were right all along. |
| Including all types of emissions shortens timeline to reach Paris Agreement temperature targets Posted: 06 Jun 2022 08:15 AM PDT Looking beyond carbon dioxide emissions to include other human-generated pollutants, like methane, nitrogen oxide and particulate pollution, changes the picture for how much warming is already 'baked in' to the climate system. Earth will continue to warm even if all emissions cease, and Earth will be committed to reaching peak temperatures about five to 10 years before experiencing them. |
| Molecules found in mucus can thwart fungal infection Posted: 06 Jun 2022 08:15 AM PDT Researchers have identified components of mucus that can specifically interact with the fungus Candida albicans and prevent it from causing infection.
