| How a large cat deity helps people to share space with leopards in India Posted: 08 Jul 2021 02:03 PM PDT A new study documents how a big cat deity worshipped by Indigenous Peoples facilitates coexistence between humans and leopards. |
| Remotely-piloted sailboats monitor 'cold pools' in tropical environments Posted: 08 Jul 2021 02:03 PM PDT Researchers used remotely-piloted sailboats to gather data on cold air pools, or pockets of cooler air that form when rain evaporates below tropical storm clouds. These hard-to-study phenomena are thought to have broader effects on tropical weather. |
| Scientists show how light therapy treats depression in mice model Posted: 08 Jul 2021 11:39 AM PDT Light therapy can help improve the mood of people with seasonal affective disorder (SAD) during short winter days, but exactly how this therapy works is not well understood. A new study finds that light therapy's beneficial effects come from activating the circadian clock gene Period1 in a part of the brain involved in mood and sleep-wake cycles. |
| Solving the plastic shortage with a new chemical catalyst Posted: 08 Jul 2021 11:38 AM PDT In a year that has already battered manufacturing supply chains, yet another shortage is complicating manufacturers' and consumers' lives: plastics, and the food packaging, automotive components, clothing, medical and lab equipment and countless other items that rely on them. |
| Smaller turtles are nesting on Florida beaches Posted: 08 Jul 2021 10:54 AM PDT A new study indicates that smaller loggerhead and green sea turtles are nesting on Florida beaches than in the past; however, researchers aren't sure why. The findings give clues to the status of the turtles, which is important to researchers who are monitoring the population health of the threatened species. |
| Dealing with global carbon debt Posted: 08 Jul 2021 10:53 AM PDT As atmospheric concentrations of carbon dioxide continue to rise, we are putting future generations at risk of having to deal with a massive carbon debt. Researchers are calling for immediate action to establish responsibility for carbon debt by implementing carbon removal obligations, for example, during the upcoming revision of the EU Emissions Trading Scheme. |
| How fishing communities are responding to climate change Posted: 08 Jul 2021 10:53 AM PDT What happens when climate change affects the abundance and distribution of fish? Fishers and fishing communities in the Northeast United States have adapted to those changes in three specific ways, according to new research. |
| Engineering seeds to resist drought Posted: 08 Jul 2021 08:15 AM PDT Researchers have devised a way to protect seeds from the stress of water shortage during their crucial germination phase, and even provide the plants with extra nutrition. Simple and inexpensive, the process could be deployed in arid regions to facilitate agriculture on drought-stressed land. |
| Seismic monitoring of permafrost uncovers trend likely related to warming Posted: 08 Jul 2021 08:14 AM PDT Seismic waves passing through the ground near Longyearbyen in the Adventdalen valley, Svalbard, Norway have been slowing down steadily over the past three years, most likely due to permafrost warming in the Arctic valley. |
| Ancient ostrich eggshell reveals new evidence of extreme climate change thousands of years ago Posted: 08 Jul 2021 07:36 AM PDT Evidence from an ancient eggshell has revealed important new information about the extreme climate change faced by human early ancestors. |
| Collective battery storage beneficial for decarbonized world Posted: 08 Jul 2021 07:36 AM PDT Batteries are potentially a game-changing technology as we decarbonize our economy, and their benefits are even greater when shared across communities, a new study has found. |
| To predict underwater volcano eruptions, scientist looks at images from space Posted: 08 Jul 2021 07:36 AM PDT A new study monitored satellite images to obtain sea discoloration data as a novel indicator in detecting if an underwater volcano's eruption is imminent. |
| Climate changed the size of our bodies and, to some extent, our brains Posted: 08 Jul 2021 05:39 AM PDT The average body size of humans has fluctuated significantly over the last million years and is strongly linked to temperature. Colder, harsher climates drove the evolution of larger body sizes, while warmer climates led to smaller bodies. Brain size also changed dramatically but did not evolve in tandem with body size. |
| Posted: 07 Jul 2021 03:53 PM PDT If global warming is not curbed, the increase in heat-related deaths will outstrip the decline in cold-related mortality, especially in the Mediterranean Basin, a new study concludes. |
| More EVs could reduce CO2 emissions in Hawaii by 93% in less than 30 years Posted: 07 Jul 2021 03:53 PM PDT By 2050, faster adoption of electric vehicles (EVs) and faster generation of renewable energy will result in 99% less fossil fuel consumed and 93% less CO2 emissions from passenger and freight vehicles on Oahu. |
| Wastewater did not significantly alter seismic stress direction in southern Kansas, study finds Posted: 07 Jul 2021 01:05 PM PDT Although wastewater disposal has been the primary driving force behind increased earthquake activity in southern Kansas since 2013, a new study concludes that the disposal has not significantly changed the orientation of stress in the Earth's crust in the region. |
| What to do with food waste? Well, that depends Posted: 07 Jul 2021 01:05 PM PDT The expected decline in the number of landfills across the United States coupled with bans on disposing large amounts of organic waste in landfills that have been enacted in multiple states has prompted researchers to examine other ways to grapple with the issue of food waste disposal. |
| How plants compensate symbiotic microbes Posted: 07 Jul 2021 01:05 PM PDT Combining economics, psychology and studies of fertilizer application, researchers find that plants nearly follow an 'equal pay for equal work' rule when giving resources to partner microbes - except when those microbes under-perform. |
| Human-driven habitat change leads to physical, behavioral change in mosquitofish Posted: 07 Jul 2021 01:04 PM PDT Bahamian mosquitofish in habitats fragmented by human activity are more willing to explore their environment, more stressed by change and have smaller brain regions associated with fear response than mosquitofish from unaffected habitats. |
| Mapping dengue hot spots pinpoints risk for Zika and chikungunya Posted: 07 Jul 2021 10:30 AM PDT Data from nine cities in Mexico confirms that identifying dengue fever 'hot spots' can provide a predictive map for future outbreaks of Zika and chikungunya. All three of these viral diseases are spread by the Aedes aegypti mosquito. |
