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

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.

Aging Is the Real Population Bomb

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.

Tethering of shattered chromosomal fragments paves way for new cancer therapies

Healthy cells work hard to maintain the integrity of our DNA, but occasionally, a chromosome can get separated from the others and break apart during cell division. The tiny fragments of DNA then get reassembled in random order in the new cell, sometimes producing cancerous gene mutations.

This chromosomal shattering and rearranging is called “chromothripsis” and occurs in the majority of human cancers, especially cancers of the bones, brain and fatty tissue. Chromothripsis was first described just over a decade ago, but scientists did not understand how the floating pieces of DNA were able to be put back together.

In a study published in Nature, researchers at University of California San Diego have answered this question, discovering that the shattered DNA fragments are actually tethered together. This allows them to travel as one during and be re-encapsulated by one of the new daughter cells, where they are reassembled in a different order.

Tiny nanopores can contribute to faster identification of diseases

In a collaboration with Groningen University, Professor Jørgen Kjems and his research group at Aarhus University have achieved a remarkable breakthrough in developing tiny nano-sized pores that can contribute to better possibilities for, among other things, detecting diseases at an earlier stage.

Their work, recently published in the journal ACS Nano, shows a new innovative method for finding specific proteins in complex biological fluids, such as blood, without having to label the proteins chemically. The research is an important milestone in , and could revolutionize medical diagnostics.

Nanopores are tiny channels formed in materials, that can be used as sensors. The researchers, led by Jørgen Kjems and Giovanni Maglia (Groningen Univ.), have taken this a step further by developing a special type of called ClyA with scanner molecules, called nanobodies, attached to it.

Scientists have identified anti-aging drugs using AI technology

Artificial intelligence (AI) and its latest contribution to the development of anti-aging drugs has paved the way for breakthrough discoveries in modern medicine.

Researchers, using AI technology, have successfully identified three chemicals that specifically target malfunctioning cells, believed to be associated with certain cancers and Alzheimer’s disease.

A group of scientists from the University of Edinburgh developed an AI algorithm to screen a collection of over 4,300 chemical compounds.

Bioprinting personalized tissues and organs within the body: A breakthrough in regenerative medicine

In situ bioprinting, which involves 3D printing biocompatible structures and tissues directly within the body, has seen steady progress over the past few years. In a recent study, a team of researchers developed a handheld bioprinter that addresses key limitations of previous designs, i.e., the ability to print multiple materials and control the physicochemical properties of printed tissues. This device will pave the way for a wide variety of applications in regenerative medicine, drug development and testing, and custom orthotics and prosthetics.

The emergence of has resulted in substantial improvements in the lives of patients worldwide through the replacement, repair, or regeneration of damaged tissues and organs. It is a promising solution to challenges such as the lack of organ donors or transplantation-associated risks. One of the major advancements in regenerative medicine is on-site (or “in situ”) bioprinting, an extension of 3D , which is used to directly synthesize tissues and organs within the human body. It shows great potential in facilitating the repair and regeneration of defective tissues and organs.

Although significant progress has been made in this field, currently used in situ bioprinting technologies are not devoid of limitations. For instance, certain devices are only compatible with specific types of bioink, while others can only create small patches of tissue at a time. Moreover, their designs are usually complex, making them unaffordable and restricting their applications.

A Conductive Self-Healing Hydrogel to Create Flexible Sensors

Recent advancements in the field of electronics have enabled the creation of smaller and increasingly sophisticated devices, including wearable technologies, biosensors, medical implants, and soft robots. Most of these technologies are based on stretchy materials with electronic properties.

While material scientists have already introduced a wide range of flexible materials that could be used to create electronics, many of these materials are fragile and can be easily damaged. As damage to materials can result in their failure, while also compromising the overall functioning of the system they are integrated in, several existing soft and conductive materials can end up being unreliable and unsuitable for large-scale implementations.

Researchers at Harbin University of Science and Technology in China recently developed a new conductive and self-healing hydrogel that could be used to create flexible sensors for wearables, robots or other devices. This material and its composition was outlined in the Journal of Science: Advanced Materials and Devices.

‘Concerning’ CT scans may cause unnecessary hospitalization for some pulmonary embolism patients

Of approximately 250,000 Americans diagnosed with acute pulmonary embolism (PE) in emergency departments each year, most are hospitalized.

But new Michigan Medicine research, published in JAMA Network Open, finds that some patients with PE, a blood clot in one or more , may be hospitalized unnecessarily due to computed tomography (CT) imaging results rather than clinical risk factors.

Approximately 40% of the patients in the study had low-risk , as defined by the Pulmonary Embolism Severity Index, or PESI score. Roughly half of the low risk patients had CT imaging features that physicians consider “concerning,” and these patients fared just as well in the hospital as those whose CT scans showed no concerning findings.
