Musk’s Tesla built the powerpack system,which can provide electricity for more than 30,000 homes, to ease SouthAustralia"s energy woes after the state was hit with a total blackout in 2016following an "unprecedented" storm.

The maverick billionaire earlier this yearoffered on Twitter to build the battery farm, and completed it last week tonarrowly beat his self-imposed deadline of having it ready in 100 days.

The battery farm is expected to help tacklepower shortages, reduce intermittencies and address demands in summer, whenmost of the country experiences its highest energy usage.

In the barely three years since biologistsdiscovered how to create these “brain organoids,” the lentil-sized structureshave taken neuroscience by storm. Starting with a recipe developed byscientists in Austria, researchers from Japan and China to Europe and NorthAmerica are seeding lab dishes with human stem cells, adding special molecules —many labs, like chili chefs, have their own secret blends — that make the stemcells morph into a variety of brain cells. They then put the dishes intospecial chambers called bioreactors that keep them warm and in gentle motionreminiscent of a womb, encouraging the cells to form blobs with working neuronsand many other features of a full-size human brain.

What is particularly remarkable about theiralternative nucleic-acid chemistry is that their new base pair isn’t linkedtogether, like normal DNA bases, by hydrogen bonding. Instead, it incorporatesbulky organic heterocyclic groups which stick to one another in water by the mutualattraction of hydrophobic units. The Scripps group has showed that a bacterialtRNA engineered to have an anticodon with one component of the non-natural paircan recognise and stick to the complementary codon in mRNA transcribed from acorresponding gene within a DNA plasmid added to the cells.

A crucial trick is to use tRNA-loadingenzymes that are not sensitive to their non-natural anticodons, such as the E.coli tRNA synthetase that loads tRNA with the amino acid serine. Theresearchers first used this system to insert serine at a position on a standardprotein – green fluorescent protein (GFP) – coded by the non-natural base pair.

Assuming that the formation of black holesfollows that of stars, the researchers calculate the rate at which black holecollisions should be detected at large redshifts. They find that beyond aredshift of about 40—where observed objects were formed during the first 65million years following the big bang—the rate of collisions should drop to lessthan one per year. This epoch should be within reach of the next generation ofgravitational-wave observatories. If these instruments find that black holeswere bumping together more often than once per year during that period, then atleast some black holes were formed before stars: They are either primordialremnants of the infant Universe or products of unusually dense regions that aremore common than predicted by current models. Finding evidence for primordialblack holes could shed light on the nature of dark matter or on the origin ofcosmic structure in the early Universe.
