Question 2

What was the 2026 Nobel Prize in Physiology or Medicine awarded for?

A. The discovery of microRNA
B. The development of mRNA vaccines
C. Discoveries concerning light-gated ion channels and optogenetics
D. Discoveries concerning peripheral immune tolerance

Answer: C. Discoveries concerning light-gated ion channels and optogenetics

Explanation: An ion channel is a tiny passage in a cell’s outer membrane. It lets charged particles called ions move in or out. Some ion channels respond to light. The laureates’ discoveries helped researchers use light-sensitive channels to control cell activity. The other choices describe research recognised by earlier Medicine Prizes.

Question 3

What does optogenetics allow researchers to do?

A. Control selected cells using light
B. Detect neutrinos using Antarctic ice
C. Estimate inflation from consumer prices alone
D. Produce one form of a molecule using a catalyst

Answer: A. Control selected cells using light

Explanation: Optogenetics gives researchers a way to influence certain cells with light. In a simplified example, a light-sensitive protein is introduced into selected cells. Researchers then use light to affect those cells and study what they do. This is a research technique; it does not mean optogenetics is a routine treatment for brain conditions.

Question 4

Which Medicine laureate is affiliated with Stanford University?

A. Peter Hegemann
B. All three
C. Georg Nagel
D. Karl Deisseroth

Answer: D. Karl Deisseroth

Explanation: Karl Deisseroth is affiliated with Stanford University. His work helped researchers use light-sensitive proteins to study nerve cells. Peter Hegemann and Georg Nagel made key discoveries about light-sensitive channels that helped provide the tools for this research.

Question 5

Who received the 2026 Nobel Prize in Physics?

A. Michael Woodford
B. Francis Halzen
C. Henri B. Kagan
D. Georg Nagel

Answer: B. Francis Halzen

Explanation: Physicist Francis Halzen received the 2026 Physics Prize for his contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos from cosmic sources. IceCube helps scientists study the universe using particles that are very difficult to detect.

Question 6

Where is the IceCube Neutrino Observatory located?

A. In the Atacama Desert
B. In the Swiss Alps
C. At the South Pole
D. In the Arctic Ocean

Answer: C. At the South Pole

Explanation: IceCube is built into Antarctic ice near the South Pole. Its sensors are placed deep below the surface. When a neutrino interacts with matter, it can produce a faint flash of light. The sensors record those flashes for scientists to study.

Question 7

What kind of particles does the IceCube observatory detect?

A. Neutrinos
B. Gravitational waves
C. Protons only
D. Sound waves from distant galaxies

Answer: A. Neutrinos

Explanation: Neutrinos are tiny particles that rarely interact with matter, so they are difficult to detect. IceCube looks for the rare flashes of light produced when a neutrino interacts in the ice. That makes it a neutrino observatory.

Question 8

What did Francis Halzen’s work help establish as a way to study the universe?

A. X-ray crystallography
B. Deep-sea sonar mapping
C. Radio astronomy only
D. Neutrino astronomy

Answer: D. Neutrino astronomy

Explanation: Astronomers often study space by observing light, including visible light and radio waves. Neutrino astronomy gives them another way to investigate cosmic events. Neutrinos can carry information from places that may be difficult to study using light alone.

Question 9

Who shared the 2026 Nobel Prize in Chemistry?

A. Henri B. Kagan and Francis Halzen
B. Henri B. Kagan and Kenso Soai
C. Anne Carson and Henri B. Kagan
D. Kenso Soai and Michael Woodford

Explanation: The two chemists shared the 2026 Chemistry Prize for research involving asymmetric catalysis, non-linear effects and autocatalysis. Their work addressed how a chemical reaction can favour one mirror-image form of a molecule over the other.

Question 10

What is the central field of research recognised by the 2026 Nobel Prize in Chemistry?

A. Macroeconomic stabilisation
B. Neutrino astronomy
C. Asymmetric catalysis
D. Optogenetics

Answer: C. Asymmetric catalysis

Explanation: Some molecules come in two forms that are mirror images of each other, like left and right hands. Asymmetric catalysis helps a chemical reaction produce more of one form than the other. Kagan and Soai’s work advanced this field.

Question 11

In chemistry, what does “autocatalysis” broadly mean?

A. A reaction product helps catalyse the reaction that produces it
B. Light is used to control a nerve cell
C. A catalyst is removed before a reaction begins
D. A molecule is separated using Antarctic ice

Answer: A. A reaction product helps catalyse the reaction that produces it

Explanation: A catalyst helps a chemical reaction happen more easily or quickly. In autocatalysis, one of the reaction’s products helps that same reaction continue or speed up. Kenso Soai’s research showed how this process could help produce more of a particular mirror-image form of a molecule.

Question 12

Kenso Soai is associated with which country?

A. Belgium
B. France
C. Canada
D. Japan

Answer: D. Japan

Explanation: Kenso Soai was born in Hiroshima, Japan, and was affiliated with Tokyo University of Science at the time of the award. His co-laureate, Henri B. Kagan, is French.
