Old mice grow young again in study. Can people do the same? - "In Boston labs, old, blind mice have regained their eyesight, developed smarter, younger brains and built healthier muscle and kidney tissue. On the flip side, young mice have prematurely aged, with devastating results to nearly every tissue in their bodies." [more inside]
Cells, is there anything they can't do?
@SCOTTeHENSLEY: "We developed a new multivalent mRNA vaccine against all known influenza virus subtypes. Our study describing the vaccine was just published..." [more inside]
splice/never let me go: I can't wait to see you lace your shoes*
1st synthetic mouse embryos — complete with beating hearts and brains — created with no sperm, eggs or womb - "For the first time, scientists have created mouse embryos in the lab without using any eggs or sperm and watched them grow outside the womb. To achieve this feat, the researchers used only stem cells and a spinning device filled with shiny glass vials." [more inside]
Retron Library Recombineering
Scientists Have Created A New Gene-Editing Tool That Could Outperform CRISPR - "It is faster and simpler than CRISPR, enabling millions of genetic experiments to be performed simultaneously." [more inside]
minimal cells
Scientists Create Simple Synthetic Cell That Grows and Divides Normally - "New findings shed light on mechanisms controlling the most basic processes of life."[1] [more inside]
Skyscrapers for plants: maybe farm/forest arcologies should be things
Wheat yield potential in controlled-environment vertical farms - "Here we show that wheat grown on a single hectare of land in a 10-layer indoor vertical facility could produce ... 220 to 600 times the current world average annual wheat yield of 3.2 t/ha." (via) [more inside]
Higher Steaks
Will 2019 be the year of lab-grown meat? - "After years in the lab, will meats derived from animal cells finally break into the mainstream consumer market? The products could have huge implications for the planet, human health and animal welfare." [more inside]
Nexus 0.1
Chinese scientists are creating CRISPR babies - "A daring effort is under way to create the first children whose DNA has been tailored using gene editing." [more inside]
The Corn of the Future Is Hundreds of Years Old and Makes Its Own Mucus
The Wonder Plant That Could Slash Fertilizer Use - "An indigenous Mexican corn gets its nitrogen from the air."
And the plants and the animals eat each other
Insect farms gear up to feed soaring global protein demand - "Layers of squirming black soldier fly larvae fill large aluminum bins stacked 10-high in a warehouse outside of Vancouver. They are feeding on stale bread, rotting mangoes, overripe cantaloupe and squishy zucchini." [more inside]
When a gene-edited butterfly flaps its wings, evolution evolves
Scientists Can Now Repaint Butterfly Wings - "Thanks to CRISPR, scientists are studying animal evolution in ways that were previously thought to be impossible." [more inside]
GM Mosquitoes: What Could Go Wrong?
Inside the insectary - "These gene drives, they're able to copy themselves. So instead of half of the offspring inheriting the gene drive, almost all of them do. So what happens is that it spreads and it spreads and it spreads. And this is the fantastic thing. Because it allows that gene to be selfish in a population. And in a very short amount of time you can actually transform an entire wild population into a modified population. It's powerful." (previously: 1,2,3)
Genegineering
Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]
Charging toward an era of genetically modified humans
The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]
plant sex in silico
Monsanto Is Going Organic in a Quest for the Perfect Veggie - "The lettuce, peppers, and broccoli—plus a melon and an onion, with a watermelon soon to follow—aren't genetically modified at all. Monsanto created all these veggies using good old-fashioned crossbreeding, the same technology that farmers have been using to optimize crops for millennia. That doesn't mean they are low tech, exactly. Stark's division is drawing on Monsanto's accumulated scientific know-how to create vegetables that have all the advantages of genetically modified organisms without any of the Frankenfoods ick factor." [more inside]
Intelligence Tests
Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g." [more inside]
Ah, science.
New research takes steps towards finding the "gay genes." A study conducted on gay brothers in more than 100 families found several genetic regions of similarity with linkage to sexual orientation. This is kind of dense (scroll to the bottom of the page for the FAQ), but that's because it hasn't been written up in the press so there are only journal doc's and scientific summaries available.
This is the press release, which is clearer (Microsoft Word).
This is the article on the study, as published in the journal Human Genetics (PDF).

Gene Prevents 'Brains Everywhere'
Gene Prevents 'Brains Everywhere' The human version of the gene probably is not involved in keeping the human brain inside the skull, but likely plays some other role in nervous system development in human embryos, says Alejandro Sanchez Alvarado, a developmental biologist at the University of Utah School of Medicine.
Cool.
