Scientists find seven new leech species that live inside freshwater mussels

Scientists find seven new leech species that live inside freshwater mussels

Science
Nov. 11 (UPI) -- If you eat freshwater mussels, you might open a shell to find one of seven newly named leech species. Yummy. Between 2002 and 2018, Arthur Bogan, research curator of mollusks at the North Carolina Museum of Natural Sciences, recruited collaborators from all over the globe to collect freshwater mussels, sample DNA and document what they found inside. The project revealed seven new species of leeches. According to Ivan N. Bolotov, scientist of the Federal Center for Integrated Arctic Research of the Russian Academy of Sciences and one of Bogan's collaborators, at least two of the species should be classified as obligate inhabitants of the freshwater mussel's mantle cavity. These species cannot complete their life cycle without their bivalve host. "It has been suggested tha...

Oct. 22 (UPI) -- South Korean boy band Monsta X is back with a new music video. The K-pop group released an emotional video Tuesday for the song "Find You." The "Find You" video opens at the scene of a car crash. Flashbacks show Hyungwon enjoying karaoke with the other members of Monsta X before getting into a car with his parents. In the present, an injured Hyungwon is rushed to the hospital, and wakes up to learn his parents died. The members of Monsta X attempt to cheer Hyungwon up, but the singer is later seen sinking in water. "Find You" appears on Monsta X's EP Follow: Find You, which debuts Oct. 28. The EP is the group's first Korean release since the album Take.2 We Are Here, released in February. Monsta X released a music video for the song "Someone's Someone," which does not ap...
Scientists find two new species of giant parasitic wasps in Uganda

Scientists find two new species of giant parasitic wasps in Uganda

Science
Oct. 9 (UPI) -- Finnish researchers conducting field studies in Africa have discovered two new species of giant parasitic wasps. The discovery, described this week in the journal ZooKeys, suggests the group of insects known as Afrotropical rhyssine wasps is more diverse than previously thought. The largest rhyssine wasp species can grow to lengths of 10 centimeters -- nearly 4 inches. The parasitic species lay their eggs inside the larvae of other wasps and beetles that harvest rotting wood. Until now, everything that scientists knew about the group of insects in the Afrotropical region was based on just 30 specimens. "A good example of how poorly tropical rhyssines are known is the species Epirhyssa overlaeti, which is the largest African rhyssine," lead researcher Tapani Hopkins, a do...
Astronomers find star recently ripped apart by black hole

Astronomers find star recently ripped apart by black hole

Science
Sept. 26 (UPI) -- NASA's Transiting Exoplanet Survey Satellite has spotted the remnants of a star that was recently shredded by a supermassive black hole -- a first. Astrophysicists and cosmologists estimate supermassive black holes are located at the center of most galaxies. When stars wander too close, a black hole's tremendous gravitational pull can rip it apart. The violent interaction is known as a tidal disruption event, or TDE. Scientists can come to better understand the dynamics of black holes by studying the spectral signatures of TDEs. The tidal disruption event ASASSN-19bt was first spotted by an international network of telescopes called the All-Sky Automated Survey for Supernovae. TESS was able to observe the TDE, as well, providing complementary images of the event. When ...
