Bay Area storms get wetter in a warming world

Posted: 28 Apr 2022 12:22 PM PDT

Researchers used supercomputers to run high-resolution climate simulations that show how historically-impactful storm events could look in a warmer world. The researchers simulated five of the most powerful storms that have hit the San Francisco Bay Area since 1984, then projected how these historical storms would look in 2050 and 2100. They determined that some of these extreme events would deliver 26-37 percent more rain by 2100.

From seawater to drinking water, with the push of a button

Posted: 28 Apr 2022 12:22 PM PDT

Researchers created a portable desalination unit that can remove particles and salts simultaneously to generate drinking water. The user-friendly unit, which weighs less than 10 kilograms and does not require filters, can be powered by a small, portable solar panel.

Sampling the deep graveyard of Earth's earliest crust

Posted: 28 Apr 2022 11:28 AM PDT

Scientists show that remnants of the roots of Earth's first crust are still present in the terrestrial mantle and contribute to magmas erupted at the surface over Earth's history.

Finding new weapons in nature's battlesites

Posted: 28 Apr 2022 11:28 AM PDT

Interactions between microbes and other organisms are mediated by a plethora of small molecules, also called natural products. Researchers have now performed a systematic analysis of biosynthetic 'dark matter' and biological functions, thus creating a solid basis for future discovery and refinement of natural products.

Research reveals the sex secrets of amphibian singing choruses

Posted: 28 Apr 2022 11:27 AM PDT

Researchers using an 'acoustic camera' discover how individual songs in an amphibian chorus influence mating in wood frogs.

Patagonian sheepdogs are the closest living representative of the ancestor of sheepdog from UK

Posted: 28 Apr 2022 11:27 AM PDT

Modern day Patagonian sheepdogs are the closest living relative to now-extinct varieties of herding dogs of Victorian era Britain, according to a new study.

Scientists call for cap on production to end plastic pollution

Posted: 28 Apr 2022 11:26 AM PDT

An international group of experts says the production of new plastics should be capped to solve the plastic pollution problem. The authors argue that all other measures won't suffice to keep up with the pace of plastic production and releases.

Model pinpoints glaciers at risk of collapse due to climate change

Posted: 28 Apr 2022 09:54 AM PDT

Glaciologists focus on what happens at the front of glaciers that terminate in the ocean as the key to whether a glacier will speed up or slow down. Yet with global warming, meltwater is becoming increasingly important, seeping underneath and lubricating flow. A statistician included this effect in glacier flow models, concluding that the thickest and fastest moving glaciers will respond most rapidly to basal lubrication and are most vulnerable to sudden collapse.

Large bodies helped extinct marine reptiles with long necks swim, new study finds

Posted: 28 Apr 2022 09:54 AM PDT

Scientists have discovered that body size is more important than body shape in determining the energy economy of swimming for aquatic animals.

Accurately monitoring subsurface carbon dioxide storage

Posted: 28 Apr 2022 09:53 AM PDT

Capturing and storing carbon dioxide (CO2) deep underground can help combat climate change, but long-term monitoring of the stored CO2 within a geological storage site is difficult using current physics-based methods.

A prehistoric forest grows in Brunei

Posted: 28 Apr 2022 07:40 AM PDT

A new study of leaf fossils conducted in the nation of Brunei on the island of Borneo has revealed that the current dominant tree group, the dipterocarps, has dominated the rainforests for at least four million years. The findings suggest that the current landscape is similar to what was present during the Pliocene Epoch, 5.3 to 2.6 million years ago, and may provide additional justification for conservation of these forests that support many critically endangered species.

Space-based system using GPS satellites could warn of incoming tsunamis

Posted: 28 Apr 2022 07:40 AM PDT

A new method for detecting tsunamis using existing GPS satellites orbiting Earth could serve as an effective warning system for countries worldwide, according to a new study.

How to balance economic development goals with environmental conservation

Posted: 28 Apr 2022 07:39 AM PDT

An international study gives fast-growing nations a simple, inexpensive guide to inform planning and decision-making to help balance economic development goals with environmental conservation and human well-being.

Decreased genetic diversity in immune system could impact endangered toad survival

Posted: 28 Apr 2022 07:39 AM PDT

A new study examines immune system diversity in the critically endangered Wyoming toad and finds that genetic bottlenecks could impact a species' ability to respond to new pathogens. The findings could inform captive breeding strategies for endangered animal populations.

From blurry to bright: AI tech helps researchers peer into the brains of mice

Posted: 28 Apr 2022 07:39 AM PDT

Biomedical engineers have developed an artificial intelligence (AI) training strategy to capture images of mouse brain cells in action. The researchers say the AI system, in concert with specialized ultra-small microscopes, make it possible to find precisely where and when cells are activated during movement, learning and memory.

Giant marine reptiles at 2,800 meters above sea level

Posted: 28 Apr 2022 05:58 AM PDT

More than 30 years ago, researchers discovered vertebrae, ribs and a tooth in the High Alps of eastern Switzerland. The typical shape indicated that they had to originate from large marine reptiles known as ichthyosaurs, but there was a lack of corresponding comparative material. A new study has now allowed a more precise classification. According to the findings, they belong to three different ichthyosaurs of around 15 to around 20 meters in length. The tooth is particularly unusual: With a root diameter of six centimeters, it is twice as large as the largest aquatic dinosaur tooth found to date.

Bird populations in eastern Canada declining due to forest 'degradation,' research shows

Posted: 28 Apr 2022 05:58 AM PDT

Bird species that live in wooded areas are under stress from human-caused changes to forest composition, according to new research that quantifies the effects of forest 'degradation' on bird habitat.

Climate change could spark the next pandemic, new study finds

Posted: 28 Apr 2022 05:58 AM PDT

As Earth's climate continues to warm, researchers predict wild animals will be forced to relocate their habitats -- likely to regions with large human populations -- dramatically increasing the risk of a viral jump to humans that could lead to the next pandemic.

Earth's atmosphere may be source of some lunar water

Posted: 27 Apr 2022 06:13 PM PDT

Hydrogen and oxygen ions escaping from Earth's upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research.

Living in areas with more greenery may boost cognitive function, study finds

Posted: 27 Apr 2022 08:57 AM PDT

New evidence links residential exposure to greenspace, such as green vegetation, as a potential population-level approach to improve processing speed and attention, and overall cognitive function.
