Hello again, Cultivators of Curiosity!
Issue 32 of The Point by Modern Sciences is a reminder that science often gets most interesting when it widens the frame.
One piece looks at the Great Pyramid of Giza and asks whether its long life in an earthquake-prone region is part engineering, part geometry, and part luck. Another explores the brilliant and bizarre ways birds use smell to navigate, feed, and defend themselves. A third brings the focus to the future with the world’s first AI-designed vaccine, which could help researchers think beyond one strain at a time. Taken together, these stories show how much can be learned by looking again at what seems familiar, whether it is stone, scent, or a vaccine platform built with machines.
HISTORY
How the Great Pyramid of Giza has survived 4,500 years of Egyptian earthquakes
The Great Pyramid of Giza has survived thousands of Egyptian earthquakes, and engineers are now starting to explain why. A new study suggests its broad base, rigid mass, and frequency mismatch with the surrounding ground may help it resist resonance during shaking, while also cautioning that survival alone does not prove deliberate seismic design. The pyramid’s longevity is impressive, but the story is more nuanced than ancient genius alone.
The Point:
The pyramid has a helpful vibration mismatch: The study found that the Great Pyramid’s natural frequency sits well above the dominant frequency of the surrounding soil, which reduces the chance of resonance during shaking. That does not make the building earthquake-proof, but it does suggest a structural advantage that may have helped it endure for millennia.
The measurements were careful but limited: Researchers used ambient vibration testing at 37 locations because they could not damage the monument with invasive experiments. That method is useful for heritage structures, but it captures only tiny background motions, not the far stronger forces of a real earthquake.
Survival does not prove intention: The pyramid’s stability may reflect excellent empirical building choices, not necessarily a conscious plan for seismic engineering. The piece warns against survivorship bias, reminding readers that the monuments still standing are only part of the ancient architectural record.
NATURE
The brilliant and bizarre ways birds use their sense of smell – from natural cologne to pest control
Birds use their sense of smell in stranger and more useful ways than most people realize. From turkey vultures tracking carrion and kiwi probing soil for prey to seabirds using scent as a map, research shows odor can guide feeding, communication, and even pest control. The hidden world of bird smell is far richer than the old assumption that birds mainly rely on sight and hearing.
The Point:
Bird smell is doing more work than people assumed: The piece shows that odor is not a minor backup sense for birds but a key part of how many species forage, communicate, and navigate. That shifts birds from being mostly visual creatures in the popular imagination to animals living in a much more chemical world.
Examples from many species make the case: Turkey vultures, kiwi, hoopoes, auklets, long-tailed tits, petrels, and shearwaters each use smell in a different way, from finding carrion to identifying kin to creating an olfactory map across the ocean. Together, those cases show that smell can shape behavior in both subtle and dramatic ways.
The same sense can also create risk: Some seabirds mistake plastic-linked odor cues for food, which helps explain why scent-dependent species are more likely to ingest plastic. That makes bird olfaction not just a quirky biological detail, but a conservation issue tied to pollution in the modern world.
TECH
World’s first AI‑designed vaccine explained
The world’s first AI-designed vaccine marks a major step toward broader protection against future virus outbreaks. Researchers at the University of Cambridge say artificial intelligence identified stable viral features and used them to design a DNA vaccine now tested in people for the first time, raising the possibility of a broader response to coronaviruses and related pandemic threats. The results are early, but the direction is striking.
The Point:
AI is being used to target what viruses do not change: The Cambridge team trained its model to look for stable viral features shared across sarbecoviruses, rather than chasing one strain at a time. That strategy matters because viruses mutate, and vaccines that target only a narrow slice of a family can quickly lose effectiveness.
The platform offers practical advantages: DNA vaccines are generally more stable than mRNA shots, which makes them easier to store and transport, especially where cold-chain logistics are weak. The needle-free delivery method could also make mass vaccination easier during outbreaks, if the approach proves durable.
The trial is promising but still early: The first human test showed safety and antibody responses, but the immune response was modest and researchers still do not know how long protection lasts. Larger trials will decide whether this becomes a true universal vaccine platform or just an encouraging prototype.
