Researchers boost signal amplification in perovskite nanosheets      (via sciencedaily.com)     Original source 

Perovskite nanosheets show distinctive characteristics with significant applications in science and technology. In a recent study, researchers achieved enhanced signal amplification in CsPbBr3 perovskite nanosheets with a unique waveguide pattern, which enhanced both gain and thermal stability. These advancements carry wide-ranging implications for laser, sensor, and solar cell applications, and can potentially influence areas like environmental monitoring, industrial processes, and healthcare.

15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.

Whale-SETI: Groundbreaking encounter with humpback whales reveals potential for nonhuman intelligence communication      (via sciencedaily.com)     Original source 

A team of scientists had a close encounter with a non-human (aquatic) intelligence. The Whale-SETI team has been studying humpback whale communication systems in an effort to develop intelligence filters for the search for extraterrestrial intelligence. In response to a recorded humpback 'contact' call played into the sea via an underwater speaker, a humpback whale named Twain approached and circled the team's boat, while responding in a conversational style to the whale 'greeting signal.' During the 20-minute exchange, Twain responded to each playback call and matched the interval variations between each signal.

This Japanese 'dragon' terrorized ancient seas      (via sciencedaily.com)     Original source 

Researchers have described a Japanese mosasaur the size of a great white shark that terrorized Pacific seas 72 million years ago. The mosasaur was named for the place where it was found, Wakayama Prefecture. Researchers call it the Wakayama Soryu, which means blue dragon.

Adapting to hypoxia: Zooplankton influence the efficiency of the biological carbon pump in the Humboldt Current off Peru      (via sciencedaily.com)     Original source 

Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this process -- the biological carbon pump -- was thought to be particularly efficient in oxygen-poor areas. A new study suggests that the influence of certain zooplankton species on the biological carbon pump has been underestimated.

Feathered friends can become unlikely helpers for tropical coral reefs facing climate change threat      (via sciencedaily.com)     Original source 

Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs. However, there may be hope for some tropical reefs in the form of feathered friends. A new study has found that the presence of seabirds on islands adjacent to tropical coral reefs can boost coral growth rates on those reefs by more than double.
