New Cretaceous Fossil Sheds Light on Avian Reproduction[Mar 20, 2019]

A team of scientists led by Alida Bailleul and Jingmai O’Connor from the Institute of Vertebrate Paleontology and Paleoanthropology reported the first fossil bird ever found with an egg preserved inside its body. The preserved egg allows the specimen to be unequivocally identified as female, allowing scientists to test current hypotheses regarding sexual dimorphism (differences between genders).

A Chinese-American Team Synthesizes Biconcave Carbon Nanodisks for Cancer Therapy[Mar 20, 2019]

A Chinese-American joint research team developed a type of biconcave carbon nanodisk with higher tumor accumulation to enhance the anticancer drug function. In this study, biconcave carbon nanodisk has been synthesized to address the tumor accumulation of nanocarrier.

A New Method Realizes High Performance of Gas Sensor in Wavelength Modulation Spectroscopy[Mar 20, 2019]

A Chinese research group at Anhui Institute of Optics and Fine Mechanics (AIOFM), developed a novel method of laser frequency locking and intensity normalization for wavelength modulation spectroscopy (WMS), which significantly improves the stability and sensitivity of the WMS based gas sensor. The proposed method has a potential application in long-term trace gas measurement.
