How forests smell -- a risk for the climate?      (via sciencedaily.com)     Original source 

Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.

Saving endangered species: New AI method counts manatee clusters in real time      (via sciencedaily.com)     Original source 

Accurately counting manatee aggregations within a region is crucial yet challenging. Harnessing the power of AI, researchers are using a deep learning-based crowd counting approach to automatically count the number of manatees in a designated region, using images captured from CCTV cameras, which are readily available, as input. The pioneering study not only addresses the technical challenges of counting in complex outdoor environments but also offers potential ways to aid endangered species.

Can AI be too good to use?      (via sciencedaily.com)     Original source 

Much of the discussion around implementing artificial intelligence systems focuses on whether an AI application is 'trustworthy': Does it produce useful, reliable results, free of bias, while ensuring data privacy? But a new article poses a different question: What if an AI is just too good?

Best areas for rewilding European bison      (via sciencedaily.com)     Original source 

Simulations integrate historical records, fossils, and ancient DNA to reveal why the European bison nearly went extinct, and pinpoint optimal areas for conservation.   Since the near-extinction of the European bison, enormous conservation efforts have helped to restore wild populations, and its numbers are on the rise. However, the study authors argue that ensuring the species's long-term protection and recovery requires understanding why they nearly went extinct in the first place.    'Our study also suggests areas where rewilding attempts are most likely to be successful,' said lead author July Pilowsky, currently a disease ecologist at Cary Institute of Ecosystem Studies. Pilowsky completed the research while working on their PhD at University of Adelaide and University of Copenhagen.

A new brew: Evaluating the flavor of roasted, lab-grown coffee cells      (via sciencedaily.com)     Original source 

It may soon be time to wake up and smell the lab-grown coffee made from cultured plant cells. But it's not clear whether drinks from this product replicate coffee beans' complex flavors. Now, a study found that some of the comforting aromas and tastes of a conventional cup of coffee could be reproduced by roasting and brewing coffee cell cultures.

Immersive VR goggles for mice unlock new potential for brain science      (via sciencedaily.com)     Original source 

New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.

World's first logical quantum processor      (via sciencedaily.com)     Original source 

A team has realized a key milestone in the quest for stable, scalable quantum computing. For the first time, the team has created a programmable, logical quantum processor, capable of encoding up to 48 logical qubits, and executing hundreds of logical gate operations. Their system is the first demonstration of large-scale algorithm execution on an error-corrected quantum computer, heralding the advent of early fault-tolerant, or reliably uninterrupted, quantum computation.

Urbanization increases seasonal differences in plant-pollinator networks      (via sciencedaily.com)     Original source 

Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent study shows that the interactions between plants and pollinators, which are important for agricultural production, are surprisingly dynamic. For example, the plant and bee species involved in pollination vary greatly between the seasons.
