Lazy predator: A new species of mountain pitviper from China      (via sciencedaily.com)     Original source 

Researchers have discovered a new species of medium-sized venomous snake in Yunnan, China. Ovophis jenkinsi is dark brownish-grey in color with trapezoidal patches on its back. It is endemic to China's Yingjiang County and is not difficult to find in the wild. In the future, researchers plan to collect more information about this new species, including its appearance, distribution, and habits.

Lone Star State: Tracking a low-mass star as it speeds across the Milky Way      (via sciencedaily.com)     Original source 

Astronomers have discovered a rare hypervelocity L subdwarf star racing through the Milky Way. More remarkably, this star may be on a trajectory that causes it to leave the Milky Way altogether.

NASA's Webb opens new window on supernova science      (via sciencedaily.com)     Original source 

Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe's expansion rate.

Hubble finds surprises around a star that erupted 40 years ago      (via sciencedaily.com)     Original source 

Astronomers have used new data from NASA's Hubble Space Telescope and the retired SOFIA (Stratospheric Observatory for Infrared Astronomy) as well as archival data from other missions to revisit one of the strangest binary star systems in our galaxy -- 40 years after it burst onto the scene as a bright and long-lived nova. A nova is a star that suddenly increases its brightness tremendously and then fades away to its former obscurity, usually in a few months or years.

Webb telescope reveals asteroid collision in neighboring star system      (via sciencedaily.com)     Original source 

Astronomers have captured what appears to be a snapshot of a massive collision of giant asteroids in Beta Pictoris, a neighboring star system known for its early age and tumultuous planet-forming activity.

Elephants have names for each other like people do, new study shows      (via sciencedaily.com)     Original source 

Wild African elephants address each other with name-like calls, a rare ability among nonhuman animals, according to a new study. Researchers used machine learning to confirm that elephant calls contained a name-like component identifying the intended recipient, a behavior they suspected based on observation. The study suggests elephants do not imitate the receiver's call to address one another but instead use arbitrary vocal labels like humans.

In a significant first, researchers detect water frost on solar system's tallest volcanoes      (via sciencedaily.com)     Original source 

An international team of planetary scientists has detected patches of water frost sitting atop the Tharsis volcanoes on Mars, which are not only the tallest volcanic mountains on the Red Planet but in the entire solar system.

Galactic bloodlines: Many nearby star clusters originate from only three 'families'      (via sciencedaily.com)     Original source 

Astronomers have deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team reports that most nearby young star clusters belong to only three families, which originate from very massive star-forming regions. This research also provides new insights into the effects of supernovae (violent explosions at the end of the life of very massive stars) on the formation of giant gas structures in galaxies like our Milky Way.

Small, cool and sulfurous exoplanet may help write recipe for planetary formation      (via sciencedaily.com)     Original source 

Astronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide. Astronomers hope the discovery of this exoplanet's sulfurous atmosphere will advance our understanding of how planets forms.

In new experiment, scientists record Earth's radio waves from the moon      (via sciencedaily.com)     Original source 

Odysseus, a tenacious lander built by the company Intuitive Machines, almost didn't make it to the moon. But an experiment aboard the spacecraft managed to capture an image of Earth as it might look to observers on a planet far from our own.

Fish out of water: How killifish embryos adapted their development      (via sciencedaily.com)     Original source 

The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.

Exotic black holes could be a byproduct of dark matter      (via sciencedaily.com)     Original source 

In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain all the dark matter that we can't see today.
