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.

The government’s actions prompted sharp rebuke. Many people criticised the authorities for appropriating funds without prior consent or notification, especially for a matter as important as social security funds. As the public searched for the reason behind this, some people pointed out the precarious state of the existing pension and medical insurance funds, which are very low, and underscored the severe challenges confronting the nation. To mitigate this crisis, the CCP is reportedly exploring various reform measures, including the integration of Shenzhen’s social security system with that of Guangdong Province, to pool and coordinate the two funds together.

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.

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.

Superfast, subatomic-sized particles called muons have been used to wirelessly navigate underground for the first time. By using muon-detecting ground stations synchronized with an underground muon-detecting receiver, researchers at the University of Tokyo were able to calculate the receiver’s position in the basement of a six-story building.

As GPS cannot penetrate rock or water, this new technology could be used in future search and rescue efforts, to monitor undersea volcanoes, and guide autonomous vehicles underground and underwater. The findings are published in the journal iScience.

GPS, the , is a well-established navigation tool and offers an extensive list of positive applications, from safer air travel to real-time location mapping. However, it has some limitations. GPS signals are weaker at and can be jammed or spoofed (where a counterfeit signal replaces an authentic one). Signals can also be reflected off surfaces like walls, interfered with by trees, and can’t pass through buildings, rock or water.

IBM in collaboration with UC Berkeley researchers announced a recent breakthrough experiment which indicates that quantum computers will soon surpass classical computers in practical tasks.

Now, the company is taking another major step that has never been done before by it. The company is making the 127-qubit quantum computer publicly available over IBM Cloud.

The IBM researchers measured the noise in each qubit and extrapolated their measurements to predict the system’s behaviour without noise. They successfully ran calculations involving all 127 qubits of the Eagle processor, marking the largest reported experiment of its kind.
