• Disappearing Y chromosomes may indicate a gradual decline of male characteristics, potentially leading to a future dominated by females.
• The Y chromosome, crucial for male sex determination, is shrinking and has significantly lost active genes over millions of years.
• The degeneration of the Y chromosome is attributed to its repetitive ‘junk DNA’ composition and lack of genetic recombination in males.
• The extinction of men is a possibility, but there may be potential for evolving new sex-determining mechanisms, as seen in certain species like spiny rats.
• Future human evolution could lead to different species with varied sex-determination systems, but current research suggests the human race remains stable for now.

• Dark matter WIMP detector LUX-ZEPLIN, the world’s most sensitive detector, has failed to find evidence of WIMPs after analyzing nine months of data.
• Despite being five times more sensitive than previous detectors, LUX-ZEPLIN has yet to detect any WIMPs, leading researchers to rule out certain mass thresholds for these particles.
• The search for dark matter continues as scientists explore other potential candidates beyond WIMPs, such as axions and primordial black holes.
• Future detectors, like SABRE South in Australia, aim to enhance the search for dark matter by using different target materials, potentially capturing signals that LUX-ZEPLIN missed.
• The ongoing research is crucial for understanding dark matter, even if current efforts to detect WIMPs have not yielded results.
