AI Builds a Virus Nobody Has Ever Seen

For the first time, artificial intelligence has designed entirely new viruses in a lab — and the implications are dizzying.

Picture a virus that has never existed anywhere on Earth — not in a rainforest bat, not in a deep-sea vent, not in a frozen mammoth. Now picture a computer dreaming one up from scratch. That is exactly what happened, and it was published in the journal Science. Researchers used an AI model to generate novel viruses that had never been seen before in nature.

The system did not simply copy existing viral blueprints and shuffle the pieces around. Instead, it produced genuinely new viral proteins — structures that fold and function like the real thing, yet belong to no known species. Think of it as the difference between remixing an old song and composing an entirely new one. The laboratory tests confirmed that these AI-designed viruses were biologically plausible: they behaved the way real viruses do.

Why does this matter? Because viruses are not just threats. They are also tools. Scientists on several continents already use viruses to deliver gene therapies, attack tumours, and probe the mechanics of cells.

  • What is the difference between 'discovering' a virus and 'inventing' one, and does it matter?
  • Should there be international laws controlling who can use AI to design new viruses?
  • How might AI-designed viruses change the future of medicine and gene therapy?

Where Is Everybody? Science Still Wonders

In 1950, Enrico Fermi sat down to lunch at Los Alamos and dropped a question that still haunts scientists today: "Where is everybody?" The universe is 13.8 billion years old. It should be teeming with civilisations far more advanced than ours. Yet we have found nothing. Not a signal, not a shadow. Since Copernicus displaced Earth from the centre of the cosmos, science has insisted our planet is statistically ordinary — which means intelligent life should be everywhere.…

When Earthquakes and Heat Waves Collide

In late July, a deadly earthquake struck Kumamoto, Japan, killing at least 38 people. Then something almost crueller arrived: temperatures hit 40°C — a record — trapping nearly 7,000 survivors in sweltering shelters. Scientists call this a "compound event." The earthquake shattered water pipes and cut electricity, eliminating the very cooling systems people needed most. Older adults and infants faced heatstroke. Rescue workers slowed down as fatigue mounted. Neither disaster alone tells the full story.…

2GRAMMAR FOCUS
Wish and if only — expressing regret
Use 'wish' or 'if only' + past simple to express regret about a present situation, or + past perfect to express regret about a past situation. These structures signal that the speaker wants reality to be different.
had · were · knew · could · had controlled · had not shattered · existed
  1. Biosecurity experts wish they who would control AI virus technology before it was published.
  2. If only the earthquake the water pipes — survivors would have had working cooling systems.
  3. Scientists wish intelligent life somewhere else in the universe, but so far the silence continues.
  4. Rescue workers in Kumamoto wish they rest in cooler conditions as fatigue mounted in the 40°C heat.
  5. Emergency planners wish they about the danger of compound events before the earthquake and heatwave struck together.
  6. If only Fermi's question an answer — scientists have wondered for over seventy years where everybody is.
3DEPENDENT PREPOSITIONS
Complete each phrase with the correct preposition. All from today's articles.
  1. Scientists on several continents use viruses to probe the mechanics ___ cells.
  2. The AI model did not belong ___ any known species.
  3. Biosecurity experts are asking harder questions ___ who controls the technology.
  4. Rescue workers slowed down as fatigue mounted, trapping survivors ___ sweltering shelters.
  5. Since Copernicus displaced Earth ___ the centre of the cosmos, science has insisted our planet is ordinary.
4CRITICAL THINKING
The Fermi Paradox and AI-designed viruses are connected by a shared tension: both reveal that the absence of something — alien signals, naturally occurring viral blueprints — no longer means it cannot exist. Does the ability to invent what nature has not yet produced make humanity more powerful, more dangerous, or simply harder to define?
