  • Short-wavelength lasers based on wide-bandgap GaN photonic crystals are promising for high-brightness illumination and materials processing. Here, the authors develop a nano-fabrication method for GaN/air photonic crystals, achieving high lasing operation performance in terms of output power, beam quality, and low threshold current.

  • Southeast Asia’s forests play important roles in the society, but the region is a deforestation hotspot. Here, the authors examined the future changes in the region’s forests under different scenarios and found that by 2050 under a regional rivalry/rocky road scenario, the region’s forests would shrink by 5.2 million ha.

  • Evaluating the heat risk among city dwellers is important. Here, the authors assessed the heat risk in Philippine cities using remote sensing data and social-ecological indicators and found that the cities at high or very high risk are found in Metro Manila, where levels of heat hazard and exposure are high.

  • The notion of chirality in dynamical systems with broken spatial symmetry but preserved time inversion symmetry has led to the concept of truly chiral phonons. These have now been observed in bulk HgS using circularly polarized Raman spectroscopy.

  • Rikako Kato et al. use PET imaging to examine altered brain activity in blindsight macaques that lack visual awareness yet can still perform visuomotor tasks. They report that blindsight macaques exhibit a significant change in activity of the lateral bank of the intraparietal sulcus (lbIPS) bilaterally, and injection of muscimol into this region impairs visuomotor performance. These results suggest a role for the bilateral lbIPS in visuomotor function in blindsight conditions.
