Posted: 17 Jun 2021 01:37 PM PDT By cleverly combining complementary sequencing techniques, researchers have deepened our understanding of the function of known RNA molecules and discovered thousands of new RNAs. A better understanding of our transcriptome is essential to better understand disease processes and uncover novel genes that may serve as therapeutic targets or biomarkers. |
A new rapid assessment to promote climate-informed conservation and nature-based solutions Posted: 17 Jun 2021 01:37 PM PDT |
Sulfur enhances carbon storage in the Black Sea Posted: 17 Jun 2021 01:36 PM PDT The depths of the Black Sea store comparatively large amounts of organic carbon. A research team has now presented a new hypothesis as to why organic compounds accumulate in this semi-enclosed sea and other oxygen-depleted waters. Reactions with hydrogen sulfide play an important role in stabilizing carbon compounds, the researchers posit. This negative feedback in the climate system could counteract global warming over geological periods. |

Passive rewilding can rapidly expand UK woodland at no cost Posted: 17 Jun 2021 11:58 AM PDT A long-term passive rewilding study has shown that natural woodland regeneration could make a significant contribution to meeting the UK's ambitious tree planting targets - potentially at no cost and within relatively short timescales. The research found natural growth due to seed dispersal by birds, mammals and wind can produce biodiverse and resilient woodland. |

Coelacanths may live nearly a century, five times longer than researchers expected Posted: 17 Jun 2021 11:36 AM PDT |
Long-term Himalayan glacier study Posted: 17 Jun 2021 10:38 AM PDT The glaciers of Nanga Parbat - one of the highest mountains in the world - have been shrinking slightly but continually since the 1930s. This loss in surface area is evidenced by a long-term study. The geographers combined historical photographs, surveys, and topographical maps with current data, which allowed them to show glacial changes for this massif in the north-western Himalaya as far back as the mid-1800s. |

Wild chimpanzee orphans recover from the stress of losing their mother Posted: 17 Jun 2021 10:37 AM PDT Chronic stress could be one reason why some animal orphans have shorter lives and less offspring. Researchers assessed if, as orphan humans, orphan chimpanzees are exposed to chronic stress. They found that maternal loss is stressful but orphans experience little chronic stress since stress hormones return to normal after two years, possibly thanks to care provided by other chimpanzees. |
Historical climate effects of permafrost peatland surprise researchers Posted: 17 Jun 2021 10:37 AM PDT Peatlands are an important ecosystem that contribute to the regulation of the atmospheric carbon cycle. A multidisciplinary group of researchers investigated the climate response of a permafrost peatland located in Russia during the past 3,000 years. Unexpectedly, the group found that a cool climate period, which resulted in the formation of permafrost in northern peatlands, had a positive, or warming, effect on the climate. |
Posted: 17 Jun 2021 08:55 AM PDT Outside the breeding season many parrots live in dynamic social systems in which individuals travel and forage. These flocks are characterized by frequent changes in composition and their dynamic nature entails a unique set of challenges, such as potential increased aggression and competition for resources. Therefore, the ability to selectively choose the right flock members may be essential to maximize individual fitness. |

New method could reveal what genes we might have inherited from Neanderthals Posted: 17 Jun 2021 08:55 AM PDT Using neural networks, researchers have developed a new method to search the human genome for beneficial mutations from Neanderthals and other archaic humans. These humans are known to have interbred with modern humans, but the overall fate of the genetic material inherited from them is still largely unknown. Among others, the researchers found previously unreported mutations involved in core pathways in metabolism, blood-related diseases and immunity. |

Mutant genes can promote genetic transfer across taxonomic kingdoms Posted: 17 Jun 2021 07:12 AM PDT Researchers now have a better understanding of the mechanism underlying how certain bacteria can transfer genetic material across taxonomic kingdoms, including to fungi and protists. Their work could have applications in changing how bacteria perform certain functions or react to changes in their environment. |
Best strategy to reduce human-bear conflict Posted: 17 Jun 2021 07:12 AM PDT Conservationists have long warned of the dangers associated with bears becoming habituated to life in urban areas. Yet, it appears the message hasn't gotten through to everyone. News reports continue to cover seemingly similar situations -- a foraging bear enters a neighbourhood, easily finds high-value food and refuses to leave. The story often ends with conservation officers being forced to euthanize the animal for public safety purposes. |
When tyrannosaurs dominated, medium-sized predators disappeared Posted: 17 Jun 2021 07:12 AM PDT A new study shows that medium-sized predators all but disappeared late in dinosaur history wherever Tyrannosaurus rex and its close relatives rose to dominance. In those areas -- lands that eventually became central Asia and Western North America -- juvenile tyrannosaurs stepped in to fill the missing ecological niche previously held by other carnivores. |
Alpine plant spins its own flavonoid wool Posted: 17 Jun 2021 07:12 AM PDT Like the movie version of Spider-Man who shoots spider webs from holes in his wrists, a little alpine plant has been found to eject cobweb-like threads from tiny holes in specialized cells on its leaves. It's these tiny holes that have taken plant scientists by surprise because puncturing the surface of a plant cell would normally cause it to explode like a water balloon. |
