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."

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."

New Internet Speed World Record: 178 Terabits a Second

 Big numbers go over our heads. So here's some perspective:

"the research team led by Dr. Lidia Galdino (UCL Electronic & Electrical Engineering), achieved a data transmission rate of 178 terabits a second (178,000,000 megabits a second) – a speed at which it would be possible to download the entire Netflix library in less than a second."

Physicists: Wormholes Large Enough to Travel Through Are Possible

 Intriguing but not what we'd hoped for: "These theoretical wormholes would blink travelers 10,000 lightyears away in a single second, though thanks to the quirks of special relativity an observer from Earth would see the journey take 10,000 years":

Why We Believe Planting 1 Trillion Trees Can Save the Planet

Worth keeping in mind: "This effort could capture an estimated 200 gigatonnes of carbon over the coming decades, an amount equal to two-thirds of the pollution produced since the Industrial Revolution. But it will take time for young trees to capture the same amount of CO2 as mature forests."

Chernobyl fungus could shield astronauts from cosmic radiation

"Extrapolating these results, the researchers estimated that a roughly 8-inch layer of C. sphaerospermum "could largely negate the annual dose-equivalent of the radiation environment on the surface of Mars." That would be a significant benefit to astronauts. After all, an astronaut who is one year into a Mars mission would have been exposed to roughly 66 times more radiation than the average person on Earth."

Learning of Foreign Language Sounds Boosted by Non-invasive Nerve Stimulation

"By the end of the training, those participants were 13% better on average at classifying tones and reached peak performance twice as quickly as control participants who wore the tVNS device but never received stimulation."

Tesla’s Ambitious Plan To Ditch Cobalt

"The electric car supply chain is also heavily dependent on cobalt, a pricey metal that makes electric cars so prohibitively expensive for most consumers, with the battery’s cobalt content accounting for an astonishing 40 percent of the car’s total value. Now, however, it looks like Tesla is poised to disrupt the entire EV market and supply chain with new innovation by taking on both lithium and cobalt. “As Tesla plans next-generation electric vehicle batteries, focus is turning to lithium-iron, not the lithium-ion that has been the fundamental chemical engineering science powering EVs to date."

Parkinson’s Disease Eliminated in Mice by One-Time Genetic Treatment that Generates New Neurons

"Just a single treatment to inhibit PTB in mice converted native astrocytes, star-shaped support cells of the brain, into neurons that produce the neurotransmitter dopamine. As a result, the mice’s Parkinson’s disease symptoms disappeared."

Most Cost Effective Solar Power Systems: Double-Sided Panels That Follow the Sun

"Solar power systems with double-sided (bifacial) solar panels — which collect sunlight from two sides instead of one — and single-axis tracking technology that tilts the panels so they can follow the sun are the most cost-effective to date, researchers report June 3rd in the journal Joule. They determined that this combination of technologies produces almost 35% more energy, on average, than immobile single-panel photovoltaic systems, while reducing the cost of electricity by an average of 16%"

Scientists Create Synthetic Red Blood Cells That Mimic Natural Ones, Plus Have New Abilities

Very cool:

"The researchers loaded the artificial cells with either hemoglobin, an anticancer drug, a toxin sensor or magnetic nanoparticles to demonstrate that they could carry cargoes. The team also showed that the new RBCs could act as decoys for a bacterial toxin. Future studies will explore the potential of the artificial cells in medical applications, such as cancer therapy and toxin biosensing, the researchers say."
