Johnson & Johnson’s clinical trial of its COVID-19 vaccine was paused after a volunteer came down with an unexplained illness. The company did not disclose what the illness was, citing the participant’s privacy. The illness is still under investigation.
A new low-cost nanogenerator that can efficiently harvest electrical energy from ambient wind has been created by Ya Yang at the Beijing Institute of Nanoenergy and Nanosystems of the Chinese Academy of Sciences and colleagues.
Researchers at the University of Tokyo and Japan’s National Institute of Radiological Sciences demonstrated that positronium, which forms in tissues due to positron emission from a radiopharmaceutical agent, decays differently depending upon its chemical environment, and is especially sensitive to local oxygen saturation.
American women living in states with less restrictive reproductive rights policies are less likely to give birth to low-birth weight babies, according to a new study in the American Journal of Preventive Medicine, published by Elsevier.
Researchers at Kumamoto University, Japan generated mice lacking the estrogen receptor beta (ERβ) gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal muscle in female mice.
The formation of nanometre-sized crystals can even in low concentrations temporarily change the viscosity of magma and lead to violent volcanic eruptions. That is the conclusion of geophysicists in the UK, Germany and France, who say that their research helps to explain how otherwise calm and predictable volcanoes can turn unexpectedly explosive.
Earth is about to get a temporary mini-moon and this one might be space junk. Researchers are tracking an object that looks like it will be captured by Earth’s gravity for just a few months this winter before safely heading back out into the Solar System. It might be a standard asteroid, but some astronomers say that the mystery object’s path indicates that it could be a part of a 1960s era rocket.
The head of Russia’s space program said that NASA’s plans to send people back to the Moon are “too US-centric” for Russia to participate. He has been critical of the program in the past and now says that Russia would only be open to participating if the Moon plans were more focused on international cooperation.
A new study indicates that women who were diagnosed with cancer as adolescents or young adults can be especially vulnerable to these effects. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society (ACS).
β-1,4-glucanase, a cell wall degrading enzyme, is integral for plant parasitism and cross-species grafting in the plant family Orobanchaceae. Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena.
