Abstracts open today for the ISSCR 2022 Annual Meeting, the most comprehensive gathering of scientists in stem cell research and regenerative medicine in the world. Taking place 15-18 June 2022 in San Francisco, USA, the event offers in person and virtual opportunities share knowledge, collaborate, network, and discover the year’s most compelling stem cell science.

Ocean predators cannot survive on average concentrations of food found in the water. Instead, they survive by exploiting small patches of food-rich areas peppered throughout the world's waterways. Using active acoustics, researchers found the ocean is widely populated with narrow hotspots of activity. Traditionally, these hotspots are missed with conventional sampling tools, but locating them can provide dynamic layered maps of ocean life. The findings signify ocean food and biota as patchy, varying with depth and location, suggesting animals must find and exploit small-scale aggregations of resources.

Scientists now have a deeper understanding of how a fungus develops a symbiotic lifestyle inside grass leaf and why the grass leaf fails to defend itself against the intruder, thanks to research coming from Massey University in New Zealand and the University of Münster in Germany.

Biomedical engineers at Duke University have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The new “dual-axis” approach opens new possibilities for OCT to be used in applications such as spotting skin cancer, assessing burn damage and healing progress, and guiding surgical procedures.

Coral sperm require a specific pH to move, according to research from the School of Arts & Sciences, which identified a signaling pathway that is shared by organisms including humans. The results have implications for how corals may fare in shifting marine conditions due to climate change.

The Norwegian wolf died out in the wild a long time ago. The wolves in Norwegian forests today are Finnish. Inbreeding is making them prone to extinction as well.
