| What a Martian meteorite can teach us about Earth's origins Posted: 12 Jul 2022 04:05 PM PDT What do Mars and Iceland have in common? These days, not so much. But more than 4.5 billion years ago, it's possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest martian fragments found on Earth, could provide information about our planet that was lost over billions of years of geological movement and could help explain why the Earth developed into a planet that sustains a broad diversity of life and Mars did not. |
| Efficient, stable, and eco-friendly thermoelectric material discovered Posted: 12 Jul 2022 11:14 AM PDT A thermoelectric metal oxide film with a thermoelectric figure of merit of ~0.55 at 600°C has been discovered, opening new avenues towards the widespread use of thermoelectric converters. |
| Nutrient imbalance in flathead lake Posted: 12 Jul 2022 11:14 AM PDT New research has found a sustained imbalance between nitrogen and phosphorus that likely has significant ecological consequences for lakes worldwide. |
| Research links national-level greenhouse gas emissions, warming and resulting economic damage Posted: 12 Jul 2022 11:13 AM PDT Study provides data on gains and losses attributable to individual countries, including the finding that a group from the world's leading national emitters of GHGs have caused $6 trillion in global economic losses through warming caused by their emissions from 1990 to 2014. |
| Soil quality critical to help some U.S. crops weather heat stress from climate change Posted: 12 Jul 2022 11:13 AM PDT The results singled out growing-degree days as the most important climatic factor and water holding capacity as the most influential soil property for crop-yield variability. |
| Posted: 12 Jul 2022 11:12 AM PDT Purple sea urchins are munching their way through California's kelp forests at a speed and scale that have stunned scientists, fishermen and divers alike. But the kelp forests have long been home to red and purple urchins, so it's clear the three species can get along. Researchers sought to determine what factors disrupt this harmony. |
| Haiti's 1860 Jour de Pâques earthquakes may have released strain in key fault zone Posted: 12 Jul 2022 11:11 AM PDT Using details from historical newspaper accounts and letters, seismologists have learned more about Haiti's 1860 Jour de Pâques (Easter Sunday) earthquake sequence, and how it might have impacted the country's most recent devastating earthquakes. |
| Scientists identify mechanism responsible for fruit and seed development in flowering plants Posted: 12 Jul 2022 07:27 AM PDT Scientists identified a gene responsible for triggering plants to develop fruits and seeds. This finding may help agriculturists bypass pollination altogether for food production, which will be beneficial in these times of rising global temperatures and dwindling pollinator populations. |
| How do cells react to micro- and nanoplastics? Posted: 12 Jul 2022 07:27 AM PDT The smaller plastic particles are, the more easily they can be taken up by cells. In addition, the shape, surface and chemical properties play an important role in answering the question of how the particles could affect human tissue, according to new research. |
| Evolve... innovate... repeat: Scientists peel back the layers of virus-host evolution and innovation Posted: 12 Jul 2022 07:27 AM PDT Scientists have uncovered an intriguing new understanding of how viruses and the hosts they infect evolve new innovations to outcompete each other. Culminating a 10-year research effort, the researchers tracked the way fitness landscapes constantly change in the ongoing struggle for survival. |
| How stressed-out plants produce their own aspirin Posted: 12 Jul 2022 07:26 AM PDT Plants protect themselves from environmental hazards like insects, drought and heat by producing salicylic acid, also known as aspirin. A new understanding of this process may help plants survive increasing stress caused by climate change. |
| Rare deep-sea brine pools discovered in Red Sea Posted: 12 Jul 2022 07:26 AM PDT Researchers recently discovered rare deep-sea brine pools in the Gulf of Aqaba, a northern extension to the Red Sea. These salty underwater lakes hold secrets into the way oceans on Earth formed millions of years ago, and offer clues to life on other planets. |
| How environmentally responsible is lithium brine mining? It depends on how old the water is Posted: 12 Jul 2022 07:26 AM PDT A groundbreaking new study comprehensively accounts for the hydrological impact of lithium mining. Since lithium is the key component of the lithium-ion batteries that are crucial for the transition away from fossil fuels and towards green energy, it is critical to fully understand how to responsibly obtain the precious element. |
| The best offense is a great defense for some carnivorous plants Posted: 11 Jul 2022 01:31 PM PDT Insect-eating plants have fascinated biologists for more than a century, but how plants evolved the ability to capture and consume live prey has largely remained a mystery. Now,scientists have investigated the molecular basis of plant carnivory and found evidence that it evolved from mechanisms plants use to defend themselves. |
| Posted: 11 Jul 2022 01:31 PM PDT The amount of carbon stored by microscopic plankton will increase in the coming century, predict researchers. |
| Bomb detectors picking up more blue whale songs in Indian Ocean Posted: 11 Jul 2022 08:18 AM PDT The good news is, pygmy blue whales appear to be thriving in the Indian Ocean. But not-so-good is that climate change may be threatening their food sources. |
| Prenatal exposure to certain phthalates associated with slightly earlier onset of puberty Posted: 11 Jul 2022 08:18 AM PDT A study provides new evidence on the possible effects of these endocrine-disrupting chemicals on sexual development. |
| Stronger overturning circulation in the Pacific during the last glacial period Posted: 11 Jul 2022 08:18 AM PDT Coral data indicate that the upper layers of Pacific Ocean were more mixed during the last Ice Age than they are today. New research shows that the Tasman Sea in the South Pacific was an important component of the global conveyor belt at that time. |
| Pocket gophers are underground root 'farmers' Posted: 11 Jul 2022 08:18 AM PDT Pocket gophers are known for living solitary, underground lives, eating roots in North and Central American grasslands. Now, researchers have found that pocket gophers keep up with the high energy demands of their burrowing lifestyle by 'farming' roots that grow into their tunnels. They calculate that these roots supply 20 to 60 percent of the gophers' need for daily calories. |
| Massive genomic study of California's biodiversity Posted: 06 Jul 2022 06:28 AM PDT The California Conservation Genomics Project (CCGP) is a state-funded initiative with a single goal: to produce the most comprehensive, multispecies, genomic dataset ever assembled to help manage regional biodiversity. The project is now in phase two, producing a series of papers that will both advance the state-of-the-art understanding of species integral to California's biodiversity and, in later phases of the CCGP, inform conservation policy. |
