How did life come about? The answer to this question goes to the very heart of our existence on planet Earth. Did life simply arise from chemical reactions among organic compounds in a primordial soup ...
Samples from the asteroid Ryugu collected by the Hayabusa2 mission contain nitrogenous organic compounds, including the nucleobase uracil, which is a part of RNA. Samples from the asteroid Ryugu ...
After encountering foreign antigen, B cells diversify their immunoglobulin genes by somatic hypermutation (SHM), gene conversion (GC) and class-switch recombination (CSR). SHM introduces mutations ...

Between October 1996 and April 2001, a total of 733 patients were randomly assigned to receive either treatment. The median follow-up time was 6.2 years. The RFS rates at 5 years were 88.0% in the CMF ...
Back in 2010, Japan’s space agency JAXA completed one of the biggest milestones in the history of space exploration: It collected samples from an asteroid and brought them back to Earth. A decade ...
Preoperative Therapy With Trastuzumab and Paclitaxel Followed by Sequential Adjuvant Doxorubicin/Cyclophosphamide for HER2 Overexpressing Stage II or III Breast ...
Tohoku University scientists have found that human editing enzymes are likely behind a type of mutation in the COVID-19 virus that stimulates the release of pro-inflammatory molecules called cytokines ...
In a recent study published in PLOS Pathogens, researchers reviewed the existing knowledge on the mechanisms through which deoxyribonucleic acid (DNA) tumor viruses (DTVs) evade the antiviral immunity ...
Uracil, a key molecule found in all living organisms, has been detected in a near-Earth asteroid. An international team of experts, led by Professor Yasuhiro Oba in Japan analysed samples from Ryugu, ...
This discovery by an international team, led by Associate Professor Yasuhiro Oba at Hokkaido University, adds to the evidence that important building blocks for life are created in space and could ...
