Roger Penrose and Stuart Hameroff have long pursued a concept – not exactly a model – of consciousness that’s based on a notion that quantum effects take place along tiny rods called microtubules that are vital structural elements inside most living cells. These rods are everywhere, but especially in neurons, and some experiments suggest that perhaps a kind of entanglement might happen along their length.
It's not laughable! Much stronger evidence supports the existence of quantum activity in the chlorophyll molecule that plants use to convert sunlight into stored chemical energy. This article offers details on the Penrose-Hameroff notion. (I watched-heard them both at a Consciousness Debate, held at the home of Irwin Jacobs, three months ago. I spoke with Penrose, several times, about his clever re-scaling explanation for how Big Bangs fit into a cyclical cosmos.)
I suspect they are about half-right about there being some quantum effects inside neurons. Even that much would be amazing, and would imply that it may take a lot more than a Moore's Law doubling of flip-flops to emulate human consciousness. See also their latest book Consciousness and the Universe: Quantum Physics, Evolution, Brain and Mind.

Might genetic meddling in actual humans be a little harder than to recent hopeful/terrifying press reports led us to believe? Our immune systems may be formidable.
“The CRISPR–Cas9 system, which functions as a genetic scissors and tape for editing DNA, is generally derived from either Staphylococcus aureusor Streptococcus pyogenes bacteria. Most people have been exposed to staph or strep by the time they reach adulthood, which their bodies are likely to remember and may mount an immune attack when re-exposed to them…. Or worse, it could trigger the kind of immune storm that killed a young gene therapy patient named Jesse Gelsinger in 1999, derailing the field for more than a decade.”

A new study showed that it is possible to recreate DNA using information from living descendants. Which may empower fellows like George Church to give us back mammoths... then dinosaurs... then maybe (as in Existence)... Neandethals?
The Food and Drug Administration has approved the very first algorithm that monitors patient vitals to predict potentially lethal events hours before they could have occurred.
If You Had a Human Head Transplant, Would You Still Be You? A topic actually explored in The Organ Bank Farm, a novel by the under-rated science fiction author John Boyd. Jim Cheetham has an answer that’s +1. 'It's a body transplant. Does that make it an easier question?'

If true, this is… wow. “In the first recorded instance of fire being used by animals other than humans, three Australian birds of prey species have been seen carrying burning twigs to set new blazes…” offering “…evidence that birds are very good at “generating innovative solutions to foraging problems.”
A fascinating and erudite article asks whether humans have some in-built morality, an ancient question with light shed by recent science.
Why Males Are Biology's Riskier Sex: This article explains some of the fantastic amounts that reproductive biologists have learned lately about sperm, eggs, mutations and how those mutations are contributed vs. age by mothers and fathers.
Fascinating. Vertebrate animals apparently use a basic information-processing system that derives from genes that infected some ancestor via a virus. That transmission and retention isn’t unusual – large fractions of our genome apparently come from viruses. But this article describes one of a myriad info-processing functions that we never knew about, till recently. When a synapse fires, it apparently triggers an RNA messenger to enfold itself into a protective capsid and travel to some adjacent neuron, where… well, this is way complicated and not easily emulated via binary flipflops and Moore’s Law.
Adding this blue dye to standard malaria treatments seems to reduce the chance new mosquitoes will pick up and vector the disease.

Alas, sometime SciFi gets it too right: Remember the lurid sci fi flick THE DAY AFTER TOMORROW? Its frenzied-fun premise was based on a real fear... now apparently coming true, as ocean circulation in the Atlantic has plunged to its lowest level in 1600 years.
Meanwhile... Coral bleaching has accelerated to a clip at which established reefs can no longer keep up. Part of it comes from pollution and warming waters, but also ocean acidification.
And the last of those three has special significance. Oh, talk about ocean acidification. Speak the phase aloud... because you’ll find that members of the Climate Denialist Cult always shout “squirrel!” or run away, when they hear those two words. Because:
(1) anyone can go to the shore and measure it for themselves; it’s happening, and serious. And...
(2) there are no possible alternative excuses – the way the cultists try to blame the sun for global warming. Ocean acidification comes from increased carbon dioxide in the atmosphere, put there by humans. Period. And those who are aiding the villains waging war on science are now as culpable – and should be as financially liable – as the Koch Brothers and their petro-sheik and oil-boyar allies.
But then... the fact people keep coming up with... hope!

A thin membrane made of graphene, called “Graphair,” which can make dirty water clean enough to drink after just a single pass through. Consumption of contaminated drinking water can transmit a number of diarrheal diseases, such as cholera, dysentery, typhoid, and polio, as well as many parasites, like giardia. In water-stressed areas that also have limited access to medical care, diarrheal illnesses can be life-threatening. The next steps for the team will be to connect with industry partners who can help them scale Graphair up for practical use.
A DARPA-funded prosthetic neural system has made progress toward improving memory by writing codes into the hippocampus of human subjects via electrodes implanted in the brain.
MIT's Media Lab has severed ties to startup Nectome which offered digital immortality to individuals through brain uploading - seeking to embalm brains while preserving the neural connections.

A new approach to 3D imagery that’s different – using lasers to push a speck of dust around to form genuine three-dimensional object views. I doubt you can apply the term "hologram."
Elon Musk's latest venture: Solar Roof tiles - made of tempered glass, promise to be durable and cost effective (with an "infinity" warranty) and power generation lasting 30 years.
Even more advance is a concept that uses the heat of solar panels to distill and purify water, while cooling the cells to make them more efficient. Built-in batteries store power for night and outages. (Something lacking in the million solar homes we have, today.)
Need more memory? Next generation optical disc storage offers 10 terabyte capacity and six century lifespan. Gimme! Seriously. Send me a sample and (if it works) I'll tout it loudly!
And finally...Lasers so powerful they might rip apart raw vacuum? It’s actually quite plausible. Hey, didn't I predict that in....
