Expanding universe mystery — An important discrepancy in measurements of the universe’s acceleration has theorists wondering whether we’ve gotten something fundamentally wrong in our understanding of the history of the universe.
One currently unexplained cosmological mystery is the ‘Hubble tension,’ where various measurements of the universe’s expansion seem to disagree. As the story surrounding this tension gets murkier, others have begun to come up with new ideas, but these attempts to explain away the difference without new physics don’t seem to hold up to scrutiny.
~ Yes, none of it holds up to mine.
3D-printed moon dust for Mars — Mars is lacking in the vast supply of natural resources we rely on here on Earth, and astronauts attempting to colonise, or even just visit, the red planet can only bring a limited supply of materials with them. The results of the European Space Agency’s latest 3D-printing experiments (main picture, above) prove it isn’t impossible, though. If there’s one thing Mars isn’t lacking, it’s dust. As a stand in for genuine Mars ingredients, researchers have turned to a simulated version of lunar soil, also known as lunar regolith. The ESA 3D-printed a sample of various parts using a light-sensitive binding agent mixed with the regolith (silicon, aluminium, calcium, and iron oxides that have been ground to a very fine dust).

Genetically-altered twins spark outrage — Twin girls born earlier in November had their DNA altered to prevent them from contracting HIV, according to an Associated Press report. If confirmed, the births would signify the first gene-edited babies in human history — a stunning development that’s sparking an outcry from scientists and ethicists.
~ He doesn’t appear to have been kidding. ‘Don’t worry, kids! We’re just going to infect you with HIV and see what happens …’
5 tech innovations that have changed music — Music is one of the fundamental appreciations that sets humans apart from every other living thing we’re currently aware of.
Beyond the artistry we connect with on an emotional level, there is a whole industry filled with gadgets, instruments and software that transforms the production and consumption of music. Read about five innovations that have revolutionised music in the last couple of decades.

Harvard scientists solve age-old lens problem — Chromatic aberration is just a fact of life when it comes to photography. A combination of high-quality gear – lenses in particular – and user skill can minimise the tell-tale purple fringe. But what if a simple layer on your lens could all but eliminate CA? Enter a team of researchers from Harvard’s School of Engineering and Applied Sciences (SEAS), who have accomplished exactly this.

It’s all going to Apocalypticon in a handcart, but here are 5 innovations that can help save the oceans from plastic — The science and tech communities have also been collaborating with governments and big business on innovative solutions to stop the eight million tonnes of plastic that is dumped into oceans every year.
~ Humans work hard to solve ridiculous but terrible problems created by … yeah, humans.
