| Major barriers to financing a sustainable ocean economy Posted: 08 Jun 2021 05:37 PM PDT Financing a sustainable global ocean economy may require a Paris Agreement type effort, according to a new report. |
| Diverse fossil flora from 400 million year ago Posted: 08 Jun 2021 05:37 PM PDT The analysis of very old plant fossils discovered in South Africa and dating from the Lower Devonian period documents the transition from barren continents to the green planet we know today. |
| The buck stops where? Longest-ever deer distance Posted: 08 Jun 2021 05:37 PM PDT Why did the deer cross the road? According to new research, to keep going and going and going. Researchers have discovered the longest distance ever recorded by an adult male white-tailed deer--300 kilometers, or close to 200 miles, in just over three weeks. The finding has important implications for population management and the transmission of disease, especially chronic wasting disease, a fatal neurological disease. |
| Keeping a closer eye on seabirds with drones and artificial intelligence Posted: 08 Jun 2021 05:37 PM PDT Drones and artificial intelligence can monitor large colonies of seabirds as well as traditional on-the-ground methods, while reducing costs, labor and the risk of human error, a new study finds. Scientists used an AI deep-learning algorithm to analyze more than 10,000 drone images of mixed colonies of seabirds in the Falkland Islands/Malvinas. The algorithm's automated counts closely matched human counts 90% of the time. |
| Peace accord in Colombia has increased deforestation of biologically-diverse rainforest Posted: 08 Jun 2021 12:45 PM PDT Since the end of the long-running conflict in Colombia, large areas of forest have been rapidly converted to agricultural uses, suggesting the peace agreement presents a threat to conservation the country's rainforest. |
| Efficiently 'switching on' bacteria to produce high-value chemicals Posted: 08 Jun 2021 12:44 PM PDT High-value chemicals used in biofuels and pharmaceuticals can be made from bacteria by switching their chemistry to produce novel products. Researchers have found a way to drastically cut the cost of turning on these switches. |
| Archaeology uncovering lost Indigenous NE Florida settlement of Sarabay Posted: 08 Jun 2021 12:44 PM PDT Archaeology team is now fairly confident they have located the lost Indigenous northeast Florida community of Sarabay, a settlement mentioned in both French and Spanish documents dating to the 1560s but had not been discovered until now. |
| Monarchs raised in captivity can orient themselves for migration Posted: 08 Jun 2021 12:44 PM PDT Researchers found monarchs raised in captivity can successfully migrate if given time to orient themselves. They discovered this by equipping the butterflies with tiny radio transmitters and monitoring them for 200 km, debunking previous research that found the butterflies couldn't orient themselves. Monarchs released into the wild flew in the proper direction because they were exposed to natural sunlight cues allowing them to calibrate their internal compasses after being released. |
| Scientists develop the 'evotype' to unlock power of evolution for better engineering biology Posted: 08 Jun 2021 12:44 PM PDT Scientists have pioneered a new approach to help biological engineers both harness and design the evolutionary potential of new biosystems. Their concept of the 'evotype' lays a foundation for the next generation of stable, safe and self-improving biotechnologies. |
| Cleaning up mining pollution in rivers Posted: 08 Jun 2021 12:44 PM PDT Mining involves moving a lot of rock, so some mess is expected. However, mining operations can continue to affect ecosystems long after activity has ended. Heavy metals and corrosive substances leach into the environment, preventing wildlife and vegetation from returning to the area. |
| Preclinical study suggests new approach to reduce COVID-19 death among the elderly Posted: 08 Jun 2021 08:32 AM PDT New research reveals a possible new approach to preventing death and severe disease in elderly people infected with SARS-CoV-2. Researchers demonstrated in a preclinical study that senolytic drugs significantly reduced mortality upon infection from a beta-coronavirus closely related to SARS-CoV-2 in older mice. |
| New population of pygmy blue whales discovered with help of bomb detectors Posted: 08 Jun 2021 08:32 AM PDT Blue whales may be the biggest animals in the world, but they're also some of the hardest to find. A team of scientists are confident they've discovered a new population of pygmy blue whales, the smallest subspecies of blue whales, in the Indian Ocean. And it was the whales' powerful singing -- recorded by underwater bomb detectors -- that gave them away. |
| A drug from resin to combat epileptic seizures Posted: 08 Jun 2021 08:32 AM PDT New molecules have promising properties as possible drugs against epilepsy. A study shows that several of the molecules have antiseizure effects. |
| Porpoises seem to cooperate in surprisingly sophisticated group hunting Posted: 08 Jun 2021 08:32 AM PDT Drone footage shows that porpoises may be more social and cooperative than previously thought. |
| Deforestation darkening the seas above world's second biggest reef Posted: 08 Jun 2021 08:31 AM PDT Converting Central American tropical forests into agricultural land is changing the color and composition of natural material washing into nearby rivers, making it less likely to decompose before it reaches the ocean, a new study has shown. |
| Snowflake morays can feed on land, swallow prey without water Posted: 08 Jun 2021 06:22 AM PDT A new study shows that pharyngeal jaws enable at least one species of moray eel to feed on land. |
| Sugar overload may be a recipe for long-term problems Posted: 08 Jun 2021 06:22 AM PDT Children who consume too much sugar could be at greater risk of becoming obese, hyperactive, and cognitively impaired, as adults, according to the results of a new study. |
| Projected acidification of the Great Barrier Reef could be offset by ten years Posted: 08 Jun 2021 05:39 AM PDT New research has shown that by injecting an alkalinizing agent into the ocean along the length of the Great Barrier Reef, it would be possible, at the present rate of anthropogenic carbon emissions, to offset ten years' worth of ocean acidification. |
| Experiments show natural selection opposes sexual selection Posted: 08 Jun 2021 05:39 AM PDT Natural selection can reverse evolution that occurs through sexual selection and this can lead to better females, new research shows. |
| Super productive 3D bioprinter could help speed up drug development Posted: 08 Jun 2021 05:39 AM PDT A new 3D bioprinter developed by nanoengineers operates at record speed -- it can print a 96-well array of living human tissue samples within 30 minutes. The technology could help accelerate high-throughput preclinical drug screening and make it less costly. |
| Being social generates larger genomes in snapping shrimp Posted: 07 Jun 2021 01:12 PM PDT A team of researchers found that within the same genus of marine snapping shrimp, Synalpheus, genome size and social behavior not only vary widely, but they are also co-evolving over time. |
| Turning off lights can save migrating birds from crashing into buildings Posted: 07 Jun 2021 01:12 PM PDT Forty years of data came together to show just how many birds can be saved by buildings turning their lights off. Using decades' worth of data and birds, researchers found that on nights when half the windows were darkened, there were 11 times fewer bird collisions during spring migration and 6 times fewer collisions during fall migration than when all the windows were lit. |
| 10,000-year-old DNA pens the first tales of the earliest domesticated goats Posted: 07 Jun 2021 01:11 PM PDT New research has revealed the genetic makeup of the earliest goat herds. The findings, assimilated from DNA taken from the remains of 32 goats that died some 10,000 years ago in the Zagros mountains, provide clues to how early agricultural practices shaped the evolution of these animals. |
| The search for mountain snow microalgae Posted: 07 Jun 2021 05:46 AM PDT The life of the microscopic algae that inhabit snow at high elevations is still relatively unknown. Researchers have therefore created the ALPALGA consortium to study this little-known world, threatened by global warming. |
