Abstract
Some of last year’s progress made in hypernuclear physics is reviewed as follows: (i) resolving the

He overbinding problem in single-Λ hypernuclei [1]; (ii) arguing that the onset of binding double-Λ hypernuclei is most likely at A=5, with the neutral systems

and

unbound by a large margin [2]; and (iii) revising the calculated value of the loosely bound

lifetime to a level of ∼20% shorter than the free Λ lifetime [3], given recent claims from relativistic heavy ion experiments that τ(

) is shorter than τΛ by as much as ≈(30±8)%. Also discussed briefly in this context is the lifetime expected for the questionable

hypernucleus.
