Positive 100% predicts whether the cancer will come back! A new milestone in ct DNA detection!
As an important method for early cancer screening, liquid biopsy is undoubtedly a hot research field in recent years. Liquid biopsy is different from the detection of solid tumor tissue, the gold standard currently used for tumor diagnosis in clinical practice. Liquid biopsy mainly detects tumor-related substances in the blood to confirm the occurrence and development of tumors.

A second home close at hand? The probe sent back data that the planet is rich in groundwater ice
On the Mauna Loa volcano in Hawaii, USA, there is a habitat and research station HI-SEAS for simulating the environment of the moon and Mars. Here, researchers live and work in this habitat and research station for several days each time. to several months. During the experiment, when researchers leave the research station for "extravehicular" activities, they need to wear heavy simulated space suits to simulate future life and work on the surface of the moon or Mars. Although this research station is only 110 square meters, it can meet the needs of these "astronauts" for living and research work. The reason why these experiments are carried out here is to prepare for future missions to the moon and Mars.
