7.5 Gravitational lensing theory may explain impossible black hole merger detected by LIGO¶

New research suggests that an anomalous gravitational wave signal from colliding black holes could have been distorted by gravitational lensing, resolving a size paradox but raising new questions.

7 Study Documents Early Onset of Peer Sexual Harassment in School¶

UK Youth Justice Board research shows sexual harassment between peers emerges as early as Grade 4, with proven sexual offences by children rising 47% in 2023–24. Many child perpetrators have themselves experienced abuse or trauma, and school-based prevention programs can reduce harmful conduct.

Proven sexual offences by children rose 47% in 2023–24 and further 6% in latest year
Sexual harassment and image-based abuse widely reported by girls in schools
Many children displaying harmful sexual behavior have experienced abuse or trauma themselves
School prevention programs teach consent, healthy relationships, and challenge harmful gender norms

7 Y chromosome loss in male tissues identified as potential early cancer warning sign¶

University of Arizona researchers found that loss of the Y chromosome in men's body tissue creates a pre-neoplastic field effect—a zone of genetic vulnerability linked to cancer development. Analysis of over 4.3 million cell nuclei from 1,000 tissue samples showed Y chromosome loss increases progressively from normal tissue through abnormal cells into tumors, with highest rates in colon, rectum, esophagus, pancreas, and lung cancers. About 40 percent of men at age 60 show Y loss, rising to 57 percent by age 90.

Analyzed 4.3 million cell nuclei from 1,000 tissue samples
Y loss highest in colon, rectum, esophagus, pancreas, and lung cancers
40% of men age 60 show Y loss; 57% by age 90
Environmental exposures like smoking increase likelihood of Y chromosome loss
