The selective breeding of dogs

...DNA letters in at least three genes: some FGF5 variants cause silky long hair in dogs such as cocker spaniels, pomeranians and long-haired chihuahuas; variants in the KRT71 can lead to curly hair and the RSP02 gene influences the formation of wiry hair, such as that seen in terriers and schnauzers. In combination, the effect when all three are found together is a coat...

Is there life on Europa?

...DNA), and ammonium cyanide (NH4CN) is a precursor for the formation of amino acids (the building blocks of proteins). For these reactions to take place, the molecules need to reach certain concentrations, and it is proposed that this might occur when they are frozen in the ice shell: as water freezes, molecules are excluded from the growing ice crystals, concentrating...

If Infinity Wars had peer review instead of script editors

...DNA. Anger should incontrovertibly trigger the Hulk stress response. Given her knowledge of the location of the Soul Stone, it is illogical for Gamora to risk going to Knowhere rather than to Nidavellir. The Avengers had multiple opportunities to kill Thanos, and it is disquieting to watch them make so many stupid mistakes. First, just as his superhero colleagues were...

Influenza: A case study

...DNA, the genomes of viruses can be constituted from either DNA or RNA and may be double- or single-stranded molecules. Usually, DNA is a double-stranded molecule with paired, complementary strands (dsDNA) and RNA is a single stranded molecule (ssRNA). However, some viruses have single-stranded DNA genomes (ssDNA) and some have double-stranded RNA genomes (dsRNA). The type...

How afraid of death are we?

...DNA. When asked, we do not seem, perhaps not even to ourselves, to fear death. Nor would we guess that thinking about death has such widespread effects on our social attitudes. But there are limits to our introspective powers. We are notoriously bad at predicting how we will feel or behave in some future scenario, and we are similarly bad at working out why we feel the...

Sperm counts

...DNA - packaged into twenty three chromosomes. At the tip of the sperm's head is a package that contains enzymes that break down protective layers on the egg's surface. Not all human sperm cells look the same. Some have two heads or no heads, some have huge heads, some have small tails or no tails, others may be bent at right angles, or have spiral tails. Many of the...

Becoming a superhero: what are the limits of human performance?

...DNA, part spider. Frighteningly, we are on the edge of genetic engineering in sport being a practical if completely undesirable possibility. In 2008 Professor Wells warned in the BMJ that “some commentators have raised concerns that genetic modification or “gene doping” will be the next step in the search for enhanced performance”. Although this still exists...
