This week's science stories reveal disturbing trends in human intelligence and technology that could reshape society in uncomfortable ways. The Flynn Effect, which saw global IQ scores steadily rising for over a century, has suddenly plateaued and may be reversing - meaning our species might have hit peak intelligence and is now sliding backwards. Meanwhile, AI companies are capitalising on human loneliness by selling virtual girlfriends that promise "non-judgmental love" for a monthly subscription fee, raising serious questions about whether we're filling genuine connection needs or creating a generation incapable of real relationships.

The intersection of technology and inequality takes a dark turn with Russian immortality research that could extend human lifespans indefinitely - but likely only for those who can afford it. This prospect of immortal billionaires ruling over mortal peasants represents the ultimate dystopian future, where death becomes a luxury only poor people experience. Adding to the apocalyptic themes, climate change could potentially trigger a fungal pandemic similar to "The Last of Us," where parasitic fungi hijack human brains and turn people into spore-spreading zombies.

Perhaps most bizarrely, nature continues to defy our understanding of basic biology with animals that can survive decapitation and keep functioning mostly normally. Cockroaches, praying mantises and even chickens have proven that losing your head isn't necessarily fatal, treating decapitation as merely an inconvenience rather than a death sentence. These stories collectively paint a picture of a world where human intelligence is declining, artificial relationships are replacing real ones, death is becoming optional for the wealthy, fungal apocalypses loom on the horizon, and some creatures have evolved beyond the need for heads - making 2025 feel like the opening chapter of several dystopian novels rolled into one.
