Drone captures narwhals using their tusks to explore, forage and play
Using drones, 17 distinct behaviors of narwhals were captured in the wild. Findings reveal complex behaviors of the Arctic's iconic whale never seen before. This highly gregarious whale uses its tusk to investigate, manipulate and influence the behavior of a fish, the Arctic char. The study also provides the first evidence of play, specifically exploratory-object play, and the first reports of kleptoparasitism, a 'food thief' situation, among narwhals and glaucous gulls.

A framework helps rail system operators or other planners identify the best joint infrastructure projects to collaborate on with other firms. Their tool can tell an operator how much to invest, the proper time to collaborate, and how the shared profits should be distributed.
Can we find floating vegetation on ocean planets?
Recent advances in astronomical observations have found a significant number of extrasolar planets that can sustain surface water, and the search for extraterrestrial life on such planets is gaining momentum. A team of astrobiologists has proposed a novel approach for detecting life on ocean planets. By conducting laboratory measurements and satellite remote sensing analyses, they have demonstrated that the reflectance spectrum of floating vegetation could serve as a promising biosignature. Seasonal variations in floating vegetation may provide a particularly effective means for remote detection.
Young star clusters give birth to rogue planetary-mass objects
How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic objects are linked to the chaotic dynamics of young star clusters.
Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. A new study suggests that these issues could be due to the excessively sterile nature of spacecraft. The study showed that the International Space Station (ISS) has a much lower diversity of microbes compared to human-built environments on Earth, and the microbes that are present are mostly species carried by humans onto the ISS, suggesting that the presence of more microbes from nature could help improve human health in the space station.
When birds lose the ability to fly, their bodies change faster than their feathers
Researchers examined dozens of bird species in museum collections looking for differences in the feathers and bodies between birds that can fly and birds that can't. They found that when birds evolve from a flying ancestor to a new flightless form, the birds' bodies, including the ratio of their wings and tails, change before the feathers do. Insights from this research could help scientists trying to determine whether a fossil bird, or a feathered dinosaur that isn't part of the bird family, was able to fly.
NASA's Hubble provides bird's-eye view of Andromeda galaxy's ecosystem
Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don't see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive.
'Fluorescent phoenix' discovered with persistence rivaling Marie Curie's
