Genomic Prediction launches its embryo selection service: “EPⓖT”
Among the genetic disorders whose phenotype risk can routinely be diagnosed by EPⓖT are:
-
300+ common single-gene disorders, such as Cystic Fibrosis, Thalassemia, BRCA, Sickle Cell Anemia, and Gaucher Disease
-
Polygenic Disease Risk, such as risk for Type 1 and Type 2 diabetes, Dwarfism, Hypothyroidism, Mental Disability, Atrial Fibrillation and other Cardiovascular Diseases like CAD, Inflammatory Bowel Disease, and Breast Cancer.

AI:
-
ALE progress:
-
“R2D2: Recurrent Experience Replay in Distributed Reinforcement Learning”, et al 2018 (new ALE/DM Lab-30 SOTA: “exceeds human-level in 52/57 ALE” games; large improvement over Ape-X using a RNN. Just 4 years after DQN, ALE borders on being solved, like ImageNet, with relatively minor tweaks to NNs. Montezuma’s Revenge remains as an exploration problem but is starting to crack under various deep exploration & intrinsic reward approaches, without requiring elaborate memory, hierarchical RL, or transfer learning from humans.)
-
“Multi-task Deep Reinforcement Learning with PopArt”, et al 2018 ( blog; median human performance on 57 ALE tasks w/1 NN using reward normalization+Impala)

-
-
“BigGAN: Large Scale GAN Training for High Fidelity Natural Image Synthesis”, et al 2018 ( source; a new GAN paper for a single 512px GAN scaling to all ImageNet categories & Google’s internal 290m+ image dataset. The samples are hilarious because some of them are astoundingly good—like dogs—but many are bizarre or well into the ‘uncanny valley’: crowdsourced amusing samples, released models & notebook, Ganbreeder for latent-space exploration; Dune-like samples)
-
WBE and DRL: a Middle Way of imitation learning from the human brain (a paradigm to keep an eye on)
-
“Alphabet’s Waymo begins charging passengers for self-driving cars”
Statistics/Meta-Science:
-
“Evaluating replicability of laboratory experiments in economics”, et al 2016 ( “About 40% of economics experiments fail replication survey”)
-
“Communicating uncertainty in official economic statistics”, 2015 (error from systematic bias > error from random sampling error in major economic statistics)

Technology:
-
Two examples of underestimating the Roman technology/economy:
-
The Nemi ships were over 70 meters long, their full scale only discovered in 1928, and used advanced technology like ball-bearings, bilge pumps, indoor plumbing, lead anchor stocks, and hulls indicative of standardized (industrial?) design & production
-
“The second century CE Roman watermills of Barbegal: Unraveling the enigma of one of the oldest industrial complexes”, et al 2018 (amazing what can be inferred from some peeled off lumps of minerals—Roman factories)
-
-
“The Invisible Library: Can digital technology make the Herculaneum scrolls legible after two thousand years?” (how much do we underestimate the Romans’ achievements because so much was lost or destroyed, and what survives is hilariously biased towards some topics like Platonism or an obscure mediocre Epicurean poet, while we assume that the best surviving instances = the best of all Roman instances?)
Economics:
-
“The Relevance of Skills to Innovation during the British Industrial Revolution, 1651–1851”, 2016

Some years ago, a company in Boston began marketing Simulated Presence Therapy, which involved making a prerecorded audiotape to simulate one side of a phone conversation. A relative or someone close to the patient would put together an “asset inventory” of the patient’s cherished memories, anecdotes, and subjects of special interest; a chatty script was developed from the inventory, and a tape was recorded according to the script, with pauses every now and then to allow time for replies. When the tape was ready, the patient was given headphones to listen to it and told that they were talking to the person over the phone. Because patients’ memories were short, they could listen to the same tape over and over, even daily, and find it newly comforting each time. There was a séance-like quality to these sessions: they were designed to simulate the presence of someone who was merely not there, but they could, in principle, continue even after that person was dead.

On “doing enough” (Yoshinori Kitase: “Death comes suddenly and there is no notion of good or bad. It leaves, not a dramatic feeling but great emptiness. When you lose someone you loved very much you feel this big empty space and think, ‘If I had known this was coming I would have done things differently.’”)
