Everywhere and nowhere: Metaverse leaders plan for data centers on a whole new scale

Posted by in categories: computing, internet

This article is part of a VB special issue. Read the full series here: Data centers in 2023: How to do more with less.

The metaverse was once pure science fiction, an idea of a sprawling online universe born 30 years ago in Neal Stephenson’s Snow Crash novel. But now it’s gone through a rebirth as a realistic destination for many industries. And so I asked some people how the metaverse will change data centers in the future.

10M Shenzhen People Social Security Pensions Disappeared; Medical Insurance Owes Hospitals 350B

Posted by in categories: biotech/medical, government

On May 8, Shenzhen citizens found a significant reduction in their social security pension balances. Some people’s accounts even shrunk a third, the most loss reached 120,000 RMB, around 17,000 USD. A wave of public outcry ensued, with aggrieved parties accusing the government of arbitrarily “pooling” their hard-earned social security funds. The controversy grew to such an extent that the balance inquiry function of the Shenzhen social security system was promptly suspended.

Following in the footsteps of Shanghai, Shenzhen has become the second major city to execute a social security coordination. Between midnight on April 24th, 2023, and 9 am on May 8th, the Shenzhen Social Insurance Information System was suspended to integrate into Guangdong Province’s system, thereby linking to the National Pension Insurance Coordinated Information System for Enterprise Employees. Upon the system’s restoration, however, a considerable number of Shenzhen residents were shocked to find that their social security account balances suddenly decreased, with some accounts seeing a drastic 30–40% plunge. The whereabouts of these diverted funds remains a mystery.

We Finally Know How Photosynthesis Starts: It Takes Just a Single Photon

Posted by in categories: biological, chemistry, quantum physics

During photosynthesis, a symphony of chemicals transforms light into the energy required for plant, algal, and some bacterial life. Scientists now know that this remarkable reaction requires the smallest possible amount of light – just one single photon – to begin.

A US team of researchers in quantum optics and biology showed that a lone photon can start photosynthesis in the purple bacterium Rhodobacter sphaeroides, and they are confident it works in plants and algae since all photosynthetic organisms share an evolutionary ancestor and similar processes.

The team says their findings bolster our knowledge of photosynthesis and will lead to a better understanding of the intersection of quantum physics in a wide range of complex biological, chemical, and physical systems, including renewable fuels.

Aging Is the Real Population Bomb

Posted by in categories: biotech/medical, food, life extension, policy

Population aging is the top global demographic trend; the pandemic can teach us how to prepare for it.

Total world population passed the 8 billion milestone on November 15, 2022. The progression from 7 to 8 billion people took a mere 12 years, conjuring up long-standing fears associated with rapid population growth, including food shortages, rampant unemployment, the depletion of natural resources, and unchecked environmental degradation.

But the most formidable demographic challenge facing the world is no longer rapid population growth, but population aging. Thoughtful preparedness—combining behavioral changes, investment in human capital and infrastructure, policy and institutional reforms, and technological innovations—can enable countries to meet the challenge and take advantage of the opportunities presented by demographic change.
