All Dark Matter in the Universe Could Be Primordial Black Holes – Formed From the Collapse of Baby Universes Soon After the Big Bang

"The first HSC observations have already reported a very intriguing candidate event consistent with a PBH [primordial black hole] from the “multiverse,” with a black hole mass comparable to the mass of the Moon. Encouraged by this first sign, and guided by the new theoretical understanding, the team is conducting a new round of observations to extend the search and to provide a definitive test of whether PBHs from the multiverse scenario can account for all dark matter."

Shadow Robot: AI Algorithms Bring Robot Hands One Step Closer to Human

This is how you rapidly improve robot performance:

Rapid Mental Rejuvenation: Experimental Drug Reverses Age-Related Cognitive Decline Within Days

Wow, this could be a serious game-changer...if it works in humans:

"Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types of prostate cancer, and even enhance cognition in healthy animals."

Faster, Smaller, Smarter and More Energy-Efficient Chips: World’s Smallest Atom-Memory Unit Created

The nanotech goal for memory size has been achieved, although the manufacturing process still needs to catch up:

"The scientific holy grail for scaling is going down to a level where a single atom controls the memory function, and this is what we accomplished in the new study."

Redesigned Current Conductors Boost Lithium-Ion Battery Efficiency and Safety

 “But in our study, making the collector 80% lighter increased the energy density of lithium-ion batteries – how much energy they can store in a given weight – by 16-26%. That’s a big jump compared to the average 3% increase achieved in recent years.”

Some Planets May Be Better for Life Than Earth: Researchers Identify 24 Superhabitable Exoplanets

 "A study led by Washington State University scientist Dirk Schulze-Makuch recently published in the journal Astrobiology details characteristics of potential “superhabitable” planets, that include those that are older, a little larger, slightly warmer and possibly wetter than Earth. Life could also more easily thrive on planets that circle more slowly changing stars with longer lifespans than our sun."

Science pays off

 "Even under very conservative assumptions, it is difficult to find an average return below $4 per $1 spent. Accounting for health benefits, inflation bias, or international spillovers can bring the social returns to over $20 per $1 spent."

Nano diamond batteries have one company all charged-up

 This sounds like it would blow pretty much all other battery technology out of the water:

Brain-Inspired Electronic System Could Make Artificial Intelligence 1,000 Times More Energy Efficient

 This is a big deal because:

"Existing AI is extremely energy-intensive — training one AI model can generate 284 tonnes of carbon dioxide, equivalent to the lifetime emissions of five cars. Replacing the transistors that make up all digital devices with memristors, a novel electronic device first built in 2008, could reduce this to a fraction of a tonne of carbon dioxide — equivalent to emissions generated in an afternoon’s drive."
