| Posted: 25 Jun 2021 02:31 PM PDT Researchers have developed a new machine learning technique to holistically assess water quality data in order to detect groundwater samples likely impacted by recent methane leakage during oil and gas production. Using that model, the team concluded that unconventional drilling methods like hydraulic fracturing do not necessarily incur more environmental problems than conventional oil and gas drilling. |

| 'Dragon man' fossil may replace Neanderthals as our closest relative Posted: 25 Jun 2021 09:04 AM PDT A near-perfectly preserved ancient human fossil known as the Harbin cranium sits in the Geoscience Museum in Hebei GEO University. The largest of Homo skulls, scientists now say this skull represents a newly discovered human species named Homo longi or 'Dragon Man.' Their findings suggest that the Homo longi lineage may be our closest relatives -- and may reshape our understanding of human evolution. |

| Mosquito love songs send mixed message about immunity Posted: 24 Jun 2021 02:08 PM PDT A new study of Aedes aegypti mosquitoes investigates how a mating cue called 'harmonic convergence' might affect immunity against parasites, bacteria and dengue virus in offspring, which has important implications for trade-offs male mosquitoes make between investing energy towards immunity or investing it on traits that impact mating and fitness. |
| Decoding humans' survival from coronaviruses Posted: 24 Jun 2021 11:22 AM PDT Researchers analyzed the genomes of more than 2,500 modern humans from 26 worldwide populations, to better understand how humans have adapted to historical coronavirus outbreaks. |
| Leopard gecko skin tumors traced to cancer gene Posted: 24 Jun 2021 11:15 AM PDT In a rare gecko color variety known as Lemon Frost, scientists have traced an unusual coloring and tendency to form tumors to a gene linked to human melanoma. |
| Scientists can predict and design single atom catalysts for important chemical reactions Posted: 24 Jun 2021 11:15 AM PDT Guided by quantum chemical calculations, scientists design and test a new single atom catalyst that converts propane to propylene with 100% efficiency, with little deactivation by coking. If adopted by industry, the catalyst could save billions of dollars and stop millions of tons of carbon dioxide being emitted into the atmosphere. |
| Glial cells help mitigate neurological damage in Huntington's disease Posted: 24 Jun 2021 10:55 AM PDT Glia affected by Huntington's disease respond by tuning down synapse genes, which has a protective effect. |
| Ethane proxies for methane in oil and gas emissions Posted: 24 Jun 2021 10:55 AM PDT Measuring ethane in the atmosphere shows that the amounts of methane going into the atmosphere from oil and gas wells and contributing to greenhouse warming is higher than suggested by the U.S. Environmental Protection Agency, according to an international team of scientists who spent three years flying over three areas of the U.S. during all four seasons. |
| Cosmic dawn occurred 250 to 350 million years after Big Bang Posted: 24 Jun 2021 10:55 AM PDT A new study suggests that the NASA James Webb Space Telescope (JWST), scheduled to launch in November, will be sensitive enough to observe the birth of galaxies directly. |
| Membrane proteins of bacteria and humans show surprising similarities Posted: 24 Jun 2021 10:55 AM PDT The cells of simple organisms, such as bacteria, as well as human cells are surrounded by a membrane, which fulfills various tasks including protecting the cell from stress. Researchers have now discovered that a membrane protein found in bacteria has a similar structure and function as a group of proteins that are responsible for remodeling and rebuilding the cell membrane in humans. No connection between the two protein groups was known before. |
| Are zebra mussels eating or helping toxic algae? Posted: 24 Jun 2021 10:55 AM PDT While invasive zebra mussels consume small plant-like organisms called phytoplankton, researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as 'blue-green algae' or cyanobacteria, that forms harmful floating blooms. |
| Natural history and conservation importance of Chinese mountain cat Posted: 24 Jun 2021 10:55 AM PDT In a large study of Chinese cats, genetic detectives highlight the evolutionary uniqueness and premier conservation importance of the elusive Chinese mountain cat (Felis silvestris bieti), found only in the Tibetan plateau of China. |
| A 'tasty' protein may lead to new ways to treat metabolic and immune diseases Posted: 24 Jun 2021 10:55 AM PDT The same taste-sensing molecule that helps you enjoy a meal from your favorite restaurant may one day lead to improved ways to treat diabetes and other metabolic and immune diseases. TRPM5 is a specialized protein that is concentrated in the taste buds, where it helps relay messages to and from cells. It has long been of interest to researchers due to its roles in taste perception and blood sugar regulation. |
| New CRISPR 3.0 system for highly efficient gene activation in plants Posted: 24 Jun 2021 10:55 AM PDT Biologists have introduced a new and improved CRISPR 3.0 system in plants, focusing on gene activation.
