Between 2018 and 2022, researchers checked in with 705 young adults interviewed as part of a much larger study on the impact of relationships when they were 15 years old. They asked participants about their current relationships with their parents, best friends and romantic partners. They found that early relationships with their mothers predicted future attachment styles with all their primary relationships.    Why this is interesting: Attachment styles suggest how avoidant or anxious people are in their relationships. People with attachment anxiety may have fears of abandonment and need more reassurance, while those with an avoidant style may struggle to rely on or trust people. Those who feel secure in their relationships are comfortable being close to others and can trust them when they need support. This new study suggests that folks who felt closer to their mothers during childhood tended to feel more secure in their adult relationships, which demonstrates the enduring impact of those first relationships, says Keely Dugan, an assistant professor of social personality psychology at the University of Missouri and lead author of the study.     What the experts say: The authors "provide some of the strongest prospective evidence to date supporting a foundational assumption of attachment theory: that early relational experiences shape how adults relate to others"—not just in general but also within specific types of relationships, says Omri Gillath, a social psychologist at the University of Kansas.—Andrea Tamayo, Newsletter Writer Mysterious Burst In July, NASA's Fermi Gamma-Ray Space Telescope spotted an unusual gamma-ray burst (GRB) in a different galaxy, some five billion light-years away. GRBs are extremely energetic explosions that rank among the most powerful astrophysical events in the universe, commonly caused by either a merging pair of neutron stars or a very massive star ending its life in a supernova called a collapsar. They are so luminous they can be seen from billions of light-years away. This one is called GRB 250702B.    Why this is interesting: In the roughly half century of GRB studies, no one has ever seen one of these epic events last more than a few hours at most. Yet this GRB lasted for nearly a full day.   What the experts say: Astronomers aren't quite sure yet what caused the giant burst. The length of the burst cannot fully be explained by the typical star collapsar scenario, nor could it have arisen from something more violent–such as a star being shredded by a black hole. "There are, of course, even wilder possibilities—it may be that this event represents some fantastic and heretofore entirely unwitnessed phenomenon," writes Yvette Cendes, a professor in the department of physics and astronomy at the University of Oregon.

A LOT goes into relationships: yes, some attachment tendencies, but also communication styles, personality compatibility, even genetics.   Let me know what you think by emailing: newsletters@sciam.com.
