Is evolution predictable?

RNA molecules are one of the key biomolecules of life as they appear in organisms as catalysts, building blocks, and information carriers. RNA is made up of sequences of chemical `letters’ called nucleotides, similar to the chemicals that make up DNA sequences. RNA sequences can... click to read more

Solving A Decade-Long Mystery: Neurons Hold The Key To Rare Neurological Diseases

While humans are 99.999% the same at the DNA level, there are small variations in our DNAs known as alleles. Most differences in our alleles are harmless, but some alleles make us more susceptible to get diseases like cancer or dementia. Understanding how these alleles... click to read more

Algae Living in Salamanders, Friend or foe?

Roughly speaking, our bodies use energy from the sun, but we can't use sunlight directly. Instead, plants and algae collect sunlight and store it as chemical energy through the process of photosynthesis. We can access that fuel directly when we eat plants, or indirectly when... click to read more
