Propagule pressure plays an important role in species invasions (Groom, 2006). Charles Darwin was the first to study specific factors related to invasions of non-native species. In his research he identified that few members of the same genus were present in habitats containing naturalized non-indigenous species (Colautti et al., 2006).
The 3 core sciences namely Biology, Chemistry, and Physics will be updated for first teaching in August 2023, with first examinations in May 2025. The syllabus change was originally scheduled for 2021, though the COVID-19 pandemic caused the IB to delay the syllabus change to 2023. Details of the specific changes can be found on the IBO website.

A 2016 study by Kumar et al. [13] chemically analyzed these secretions, concluding that they may be required in chemosensory mediated communication [14] and mate choice. Similarly, in the less aggressive herb-field mouse, males are observed to groom females for longer durations and even allow females to not reciprocate. [ 15 ]
In drug development and medical device development [1] the Investigator's Brochure (IB) is a comprehensive document summarizing the body of information about an investigational product ("IP" or "study drug") obtained during a drug trial. The IB is a document of critical importance throughout the drug development process and is updated with new ...
In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team.
Amborella trichopoda, the most basal extant angiosperm. The flowering plant family Amborellaceae, restricted to New Caledonia in the southwestern Pacific, [n 9] is a basal clade of extant angiosperms, [13] consisting of the most species, genus, family and order within the group that are sister to all other angiosperms (out of a total of about 250,000 angiosperm species).
IB Film can be taken at either the standard level (SL) or higher level (HL). For both levels of IB Film, the candidate must research and write an Independent Study, do a Practical Project and give an oral presentation, based on the close analysis of a 5-minute extract from a film prescribed by the IBO.
