Health survey suggests targeting single men to counter new COVID-19 variants

It is almost three years since the World Health Organization characterized the COVID-19 outbreak as a pandemic. Working at breakneck speed, scientists managed to produce effective vaccinations in record time. The subsequent mass production of vaccines and their rollout by governments have enabled most of us to resume our daily lives, with the pandemic gradually receding in memory.

Researchers develop new material to replace extracted human teeth for dental research

Extracted human teeth have long been used in conducting dental research, such as evaluating dental ceramic materials as a crown restoration on tooth. It is an inexpensive and straightforward process that simulates clinical situations. However, the collection and use of extracted human teeth is becoming increasingly difficult given the concerns about COVID-19, size-standardization issues, and also time constraints. All these factors have prompted a need for dentine analog materials that could potentially substitute extracted human teeth in laboratory-based mechanical and fatigue tests.

New method for image reconstruction in electrical impedance tomography

Recently, a team led by Prof. DU Jiangfeng from the Key Laboratory of Microscale Magnetic Resonance of Chinese Academy of Sciences (CAS) developed a new method for deep electrical impedance tomography reconstruction without training, which paved a new way for applying electrical impedance tomography technology in determining lesion tissue specificity. This work was published in IEEE Transactions on Pattern Analysis and Machine Intelligence.
