A Jurassic Park-inspired method can safely store data in DNA
DNA can store all types of data. An amber-like material can now protect its information long-term — or release it on demand for short-term use.

Predicting and designing protein structures wins a 2024 Nobel Prize
A biochemist and two computer scientists using AI shared the top award in chemistry.

Let’s learn about the Nobel Prize
Nobel Prizes are the highest honors in science. But the prizes are far from perfect measures of scientific impact.

Explainer: How cells use chemistry to make the electricity of life
Charged particles, or ions, constantly move in and out of cells. These migrations produce tiny electric currents, which power your brain, heart and more.

Skin appears to be no barrier for some common ‘forever’ chemicals
These PFAS, which have been linked to health problems, show up in many products that we touch every day — including clothes and food packaging.

‘Percy,’ NASA’s rover, finds its first hint of ancient life on Mars
The robot examined a Mars rock containing organic compounds and “leopard spots.” On Earth, such spots usually come from microbial life.

Metal gives the teeth of Komodo dragons their super strength
Investigating Komodo dragons' ironclad teeth in greater detail could also help solve a dental mystery in dinosaurs.

The periodic table might soon have a new element
A new technique could be used to make the undiscovered element 120.
- Genetics
Scientists Say: Telomere
These protective caps at the ends of chromosomes play a key role in cell replication.
- Materials Science
Scientists Say: Goldene
Making this metallic, two-dimensional (2-D) material is difficult — but super-thin sheets of gold could have uses in electronics and chemistry.

This spice could be the basis of a smart, infection-fighting bandage
Infused with yellow turmeric, the bandage turns red to highlight the pH of an infection. A teen showed that at the 2024 Regeneron ISEF competition.
- Chemistry
Scientists Say: Excitation
Excited electrons are to thank for dazzling fireworks displays, plants harnessing energy, the semiconductors behind modern tech and more.
