A solar garden will power all the homes and buildings on the site, cutting greenhouse gas emissions and living costs for residents of Pine Tree Park Estates, an affordable living community run by New Dawn...
Butterflies and moths have beautiful wings: The bright flare of an orange monarch, the vivid stripes of a swallowtail, the luminous green of a Luna moth. But some butterflies flutter on even more dramatic wings: Parts of their wing, or sometimes the entire wing itself, are actually transparent.
Approvals for companies to drill for oil and gas on U.S. public lands are on pace this year to reach their highest level since George W. Bush was president, underscoring President Joe Biden's reluctance to more forcefully curb petroleum production in the face of industry and Republican resistance.
Sugarcane is one of the most productive plants on Earth, providing 80 percent of the sugar and 30 percent of the bioethanol produced worldwide. Its size and efficient use of water and light give it tremendous potential for the production of renewable value-added bioproducts and biofuels.
Last autumn, researchers reported finding the gas phosphine in trace amounts in Venus' upper atmosphere, raising the slim possibility of a biological signature. Now scientists say that the phosphine's chemical fingerprints support a different find: evidence of explosive volcanoes.
A study sampled more than 1.5 million people in 269 U.S. counties and 37 European nations. Researchers found that those who grew up in areas with higher levels of atmospheric lead had less adaptive personalities in adulthood -- lower levels of conscientiousness and agreeableness and higher levels of neuroticism.
The 21 proposals include targets for reducing pesticide use, cutting plastic waste and channeling $200 billion US a year toward protecting nature in developing...
By 2100, sea levels are expected to rise by almost seven feet in the Bay Area. New research shows how traditional approaches to combating sea-level rise can create a domino effect of environmental and economic impacts for nearby communities.
Researchers have found that the magnetic field of the MRI scanner decreased the BBB opening volume by 3.3-fold to 11.7-fold, depending on the strength of the magnetic field, in a mouse model.
This pandemic year has restricted international travel for humans. Not so for some microscopic bacteria in the ocean: They partner up with clams living in the sand beneath the shimmering waters of coastal habitats throughout the globe. According to research by scientists from the Max Planck Institute for Marine Microbiology in Bremen and the University of Vienna now published in PNAS, the...
Traces of the gas phosphine point to volcanic activity on Venus, according to new research from Cornell University.
Communities trying to fight sea-level rise could inadvertently make flooding worse for their neighbors, according to a new study from the Stanford Natural Capital Project.
The sensory cells in the inner ear and the touch receptors in the skin actually have a lot in common, according to a new study from the USC Stem Cell laboratory of Neil Segil published in the Proceedings of the National Academy of Sciences (PNAS).
Pure quantum systems can undergo phase transitions analogous to the classical phase transition between the liquid and gaseous states of water. At the quantum level, however, the particle spins in states that emerge from phase transitions display collective entangled behavior. This unexpected observation offers a new avenue for the production of materials with topological properties that are useful...
Jupiter's moon Europa and its global ocean may currently have conditions suitable for life. Scientists are studying processes on the icy surface as they prepare to explore.
North Carolina State University researchers have developed a new technique that can alter plant metabolism. Tested in tobacco plants, the technique showed that it could reduce harmful chemical compounds, including some that are carcinogenic. The findings could be used to improve the health benefits of crops.
The World Health Organization published a slew of recommendations Monday on how to ensure gene editing research is used for the public good and does not get out of hand.
Over the last couple hundred years, the amount of carbon dioxide in our atmosphere has skyrocketed.
Ana Camarasa, professor of physical geography at the University of Valencia, has compared the rainfall registered in the Júcar Hydrographic Confederation between 1989 and 2018. By analyzing more than 800 rainfalls and more than 140 floods in four Valencian boulevards (including the ravines of Poyo and Carraixet, at the south and north of València) the expert concludes that in the final part of...
A study by Nanyang Technological University, Singapore (NTU Singapore) has found that as the type of COVID-19 misinformation rectified by Singapore's mainstream news media evolved over the course of the pandemic, the role played by the media in debunking those myths became increasingly important to citizens in the nation's fight to manage the outbreak.
Snowmelt—the surface runoff from melting snow—is an essential water resource for communities and ecosystems. But extreme snow melt, which occurs when snow melts too rapidly over a short amount of time, can be destructive and deadly, causing floods, landslides and dam failures.
The transportation sector is the largest contributor to greenhouse gas emissions in the United States, and a lot of attention has been devoted to electric passenger vehicles and their potential to help reduce those emissions.
Proteomics produces enormous amounts of data, which can be very complex to analyze and interpret. The free software platform MaxQuant has proven to be invaluable for data analysis of shotgun proteomics over the past decade. Now, Jürgen Cox, group leader at the Max Planck Institute of Biochemistry, and his team present the new version 2.0. It provides an improved computational workflow for...
For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has traveled an hour west of Tokyo to visit the Sagami River and collect algal samples to understand how living things evolved different sexes. Through new analysis of samples collected in 2007 and 2013 from dam lakes along the river, Lake Sagami and Lake Tsukui, researchers identified a species of freshwater algae that evolved...

Ancient sediments from caves have already been proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which confounds the analyses performed with these sequences. A study led by Ron Pinhasi and Pere Gelabert of the University of Vienna and published in Current Biology successfully retrieved three mammalian...
Rather than waiting for certainty in sea-level rise projections, policymakers can plan now for future coastal flooding by addressing existing inequities among the most vulnerable communities in flood zones, according to Stanford research.
North Carolina State University researchers found that a four-week training course made a substantial difference in helping special education teachers anticipate different ways students with learning disabilities might solve math problems. The findings suggest that the training would help instructors more quickly identify and respond to a student's needs.
