• Lasers can stop lightning from occurring.

In which year did Japanese researchers successfully trigger lightning strikes using lasers?

• 1995

• 2000

• 1999

• 1990

What is the role of laser filamentation in guiding lightning?

• It absorbs the lightning energy.

• It creates a magnetic field.

• It disperses the thunderclouds.

• It ionizes air molecules to form a plasma channel.

What is a potential future application of laser-guided lightning technology?

• To enhance solar panel efficiency.

• To create artificial rain.

• To guide lightning away from planes and rockets.

• To power electric vehicles.

What is the primary benefit of the new DNA-based test developed by Cambridge University?

• It is more expensive than PCR tests.

• It requires a larger sample size.

• It can detect viruses in under an hour.

• It can only detect one virus at a time.

How does the DNA bait in the new test identify viruses?

• By changing color when a virus is present.

• By pairing with matching RNA sequences.

• By emitting a sound signal.

• By dissolving in the presence of a virus.

What is the purpose of passing the sample through a nanopore in the new virus detection test?

• To change the sample's color.

• To sterilize the sample.

• To identify single molecules of nucleic acid.

• To magnify the sample.
