The Genetics Society of America annually honors members who have made outstanding contributions to genetics. The Thomas Hunt Morgan Medal recognizes a lifetime contribution to the science of genetics. The Genetics Society of America Medal recognizes particularly outstanding contributions to the science of genetics within the past 15 years. The George W. Beadle Medal recognizes distinguished ser...

Victor Ambros The 2006 Genetics Society of America Medal

In 1990, Victor Ambros faced a conundrum. The search for the heterochronic gene lin-4 had led him to a 700-bp DNA fragment. This fragment could rescue a lin-4mutant but contained no apparent open reading frame (ORF). The few small ORFs that could be detected were either not conserved in other nematodes or not essential for rescue. Two years and several RNAse protection experiments later, Victor...

Digressions around a medal.

"First-Aid Community Training" (F.A.C.T.) scheme has been floated to teach the general public correct attitudes towards safety in daily life. This scheme should reduce the number of accidents, and save the country millions of pounds. It is surely an intriguing paradox that in an expanding environment of state medical services a private army of trained unpaid volunteers should be flourishing. Th...

(ii) idRn ∈ G, recall idRnT = T = T idRn for any T ∈ G (iii) If T ∈ G, then T is bijective and T−1 ∈ G Proof. (i) and (ii) are fairly easy exercises. For (iii), we have that T ∈ G is surjective by definition, so only need to check one to one. For x,y ∈ R, Tx = Ty =⇒ 0 = ‖Tx−Ty‖ = ‖x−y‖ =⇒ x = y. So T is bijective, and T−1 is surjective. T−1 is an isometry since for x,y ∈ R, ‖T−1x− T−1y‖ = ‖TT−1...
