Massive Blackouts Have Hit Iran. The Government is Blaming Bitcoin Mining.

Massive blackouts and smog have hit cities across Iran. It’s a toxic mix as the country, already under economic duress and suffocating U.S. sanctions, simultaneously battles the region’s worst coronavirus outbreak. Blackouts are not new in Iran, where an aging and subsidized electricity sector is plagued by alleged mismanagement. But this time, government officials say that bitcoin mining at cryptocurrency farms…

Could Nuclear Power Be Used For Carbon Capture?

Forbes reports:
Nuclear advocates see a vast market for reactors in carbon capture and carbon-based products, not only for the next generation of reactors in development, but also for the aging dinosaurs they evolved from… The Diablo Canyon Nuclear Power Plant in San Luis Obispo, California, for example, is slated to shut down in 2024 and 2025. “If the waste heat from…

Biomarker of Alzheimer’s Found To Be Regulated By Sleep Cycles

Following a 2018 study demonstrating how disrupted sleep can accelerate the buildup of toxic plaques associated with the disease, scientists from Washington University School of Medicine (WUSM) in St. Louis have now identified a protein implicated in the progression of the disease that appears highly regulated by the circadian rhythm, helping them join the dots and providing a potential new therapeutic…

Drug Reverses Age-Related Mental Decline Within Days

The University of California San Francisco issued this glowing announcement of some new research: 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…

Reversal of Biological Clock Restores Vision In Old Mice

John Trumpian shares a report from SciTechDaily: Harvard Medical School scientists have successfully restored vision in mice by turning back the clock on aged eye cells in the retina to recapture youthful gene function. The team’s work, described today in Nature, represents the first demonstration that it may be possible to safely reprogram complex tissues, such as the nerve cells of…

Cable failures endanger renowned Puerto Rico radio telescope

Giant, aging cables that support one of the world’s largest single-dish radio telescopes are slowly unraveling in this U.S. territory, pushing an observatory renowned for its key role in astronomical discoveries to the brink of collapse.

Tesla Project To Install Another Giant Battery In Australia

An anonymous reader quotes a report from Bloomberg: France’s Neoen SA will partner with Tesla Inc. to install one of the world’s biggest lithium-ion batteries in Australia after reaching a grid connection deal with the power market operator. The 300-megawatt Victorian Big Battery will be located in the southeastern city of Geelong and use Tesla’s Megapack technology. It will be double…

The human heart in space: What can we learn from mathematical modeling

Human spaceflight has been fascinating man for centuries, representing the intangible need to explore the unknown, challenge new frontiers, advance technology and push scientific boundaries further. A key aspect of long-term human spaceflight is the physiological response and consequent microgravity (0G) adaptation, which has all the features of accelerated aging involving almost every body system: muscle atrophy and bone loss, onset…

Astronomers capture stellar winds in unprecedented detail

Astronomers have presented an explanation for the shapes of planetary nebulae. The discovery is based on a set of observations of stellar winds around aging stars. Contrary to common consensus, the team found that stellar winds are not spherical, but have a shape similar to that of planetary nebulae. The team concludes that interaction with an accompanying star or exoplanet shapes…
