Theorists could account for this force by adding a cosmological constant, lambda, to Albert Einstein’s theory of gravity.

In this study, they found that the lambda phage shares this mechanism.

The Greek letter lambda in the cosmic recipe represents one possible explanation, the cosmological constant, which Einstein himself had proposed in 1917.

Not all physicists are convinced that this diquark hypothesis reflects how lambdas really form, however.

With hepatitis treatments in mind, they had previously acquired a drug based on lambda interferons, a lesser-known type of interferon whose receptors are largely restricted to specific areas, like the respiratory tract.
