The Living Planet Index (LPI) is a leading global biodiversity indicator based on vertebrate population time series. Since it was first developed over 25 years ago, the LPI has been widely used to indicate trends in biodiversity globally, primarily reported every two years in the Living Planet Report. Based on relative abundance, a sensitive metric of biodiversity change, the LPI has also been applied as a tool for informing policy and used in assessments for several multilateral conventions and agreements, including the Convention on Biological Diversity 2010 Biodiversity Target and Aichi targets.

Article Synopsis
  • - An on-chip asymmetric directional coupler (DC) is crucial for converting fundamental modes into higher-order modes in mode-division multiplexing (MDM) technology.
  • - The study introduces a method using silicon ion implantation to adjust the effective refractive index of waveguides, achieving significant transmission changes up to 18 dB with just one implantation step.
  • - This innovative tuning technique allows for greater control over mode transmission and may enhance the efficiency and effectiveness of mode converters in integrated photonic systems, potentially benefiting emerging photonic neuromorphic computing applications.

Article Synopsis
  • Outcomes from vagus nerve stimulation (VNS) improve over time in children with drug-resistant epilepsy, but the benefits of deep brain stimulation (DBS) versus continued VNS optimization were unclear.
  • A study involving 18 children aged 8-17 showed that adding DBS after a year of ineffective VNS led to significantly greater seizure reduction (51.9% vs. 12.3%).
  • While DBS resulted in fewer bothersome seizures, it did not improve the overall quality of life, suggesting that earlier consideration of DBS could be beneficial for children not responding to VNS.

The selection and design of charge integration methods remain an outstanding challenge in materials chemistry. In complex materials like electrides, this challenge is amplified by the small charge and complex shape of electride wave functions. For these reasons, popular integration methods, such as the Bader method, usually fail to assign any charge to the bare electrons in an electride.

Lead service lines (LSLs), when present, are the largest source of lead in drinking water, and their removal is necessary to reduce public exposure to lead from drinking water. Unfortunately, the composition of many service lines (SLs) is uncertain. The town of Bennington, Vermont, for example, has unreliable SL records, making it challenging to build an inventory and conduct an LSL replacement program.
